Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. You should refer to the “ITEM 3. KEY INFORMATION: — 3. Risk factors.” section of this Annual Report for a discussion of important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties. As a result of these factors, we cannot assure you that the forward-looking statements in this Annual Report will prove to be accurate. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise. You should, however, review the factors and risks and other information we describe in the reports we will file from time to time with the Securities and Exchange Commission, or the SEC, after the date of this Annual Report.
ENFORCEMENT OF JUDGMENTS
We are a public company with limited liability (naamloze vennootschap) incorporated under the laws of the Netherlands and our headquarters is located in Germany. Substantially all of our assets are located outside the United States. The majority of our executive officers and directors reside outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon such persons or to enforce against them or us in U.S. courts, including judgments predicated upon the civil liability provisions of the federal securities laws of the United States.
The United States and the Netherlands currently do not have a treaty providing for the reciprocal recognition and enforcement of judgments, other than arbitration awards, in civil and commercial matters. Consequently, a final judgment for payment given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not automatically be recognized or enforceable in the Netherlands. In order to obtain a judgment which is enforceable in the Netherlands, the party in whose favor a final and conclusive judgment of the U.S. court has been rendered will be required to file its claim with a court of competent jurisdiction in the Netherlands.
This court will have discretion to attach such weight to the judgment rendered by the relevant U.S. court as it deems appropriate. Under current practice, the courts of the Netherlands may be expected to render a judgment in accordance with the judgment of the relevant foreign court, provided that such judgment (i) is a final judgment and has been rendered by a court which has established its jurisdiction vis-à-vis the relevant Dutch companies or Dutch company, as the case may be, on the basis of internationally accepted grounds of jurisdiction, (ii) has not been rendered in violation with the principles of proper procedure (behoorlijke rechtspleging), (iii) is not contrary to the public policy of the Netherlands, and (iv) is not incompatible with (a) a prior judgment of a Dutch court rendered in a dispute between the same parties, or (b) a prior judgment of a foreign court rendered in a dispute between the same parties, concerning the same subject matter and based on the same cause of action, provided that such prior judgment is recognizable in the Netherlands. Dutch courts may deny the recognition and enforcement of punitive damages or other awards. Moreover, a Dutch court may reduce the amount of damages granted by a U.S. court and recognize damages only to the extent that they are necessary to compensate actual losses or damages. Enforcement and recognition of judgments of U.S. courts in the Netherlands are solely governed by the provisions of the Dutch Civil Procedure Code. If no leave to enforce is granted, claimants must litigate the claim again before a Dutch competent court.
Dutch civil procedure differs substantially from U.S. civil procedure in a number of respects. Insofar as the production of evidence is concerned, U.S. law and the laws of several other jurisdictions based on common law provide for pre-trial discovery, a process by which parties to the proceedings may prior to trial compel the production of documents by adverse or third parties and the deposition of witnesses. Evidence obtained in this manner may be decisive in the outcome of any proceeding. No such pre-trial discovery process exists under Dutch law.
The United States and Germany currently do not have a treaty providing for the reciprocal recognition and enforcement of judgments, in civil and commercial matters. Consequently, a final judgment for payment or declaratory judgments given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not automatically be recognized or enforceable in Germany. German courts may deny the recognition and enforcement of a judgment rendered by a U.S. court if they consider the U.S. court not to be competent or the decision to be in violation of German public policy principles. For example, judgments awarding punitive damages are generally not enforceable in Germany. A German court may reduce the amount of damages granted by a U.S. court and recognize damages only to the extent that they are necessary to compensate actual losses or damages.
In addition, actions brought in a German court against us, our directors, our senior management and the experts named herein to enforce liabilities based on U.S. federal securities laws may be subject to certain restrictions. In particular, German courts generally do not award punitive damages. Litigation in Germany is also subject to rules of procedure that differ from U.S. rules, including with respect to the taking and admissibility of evidence, the conduct of the proceedings and the allocation of costs. German procedural law does not provide for pre-trial discovery of documents, nor does Germany support pre-trial discovery of documents under the 1970 Hague Evidence Convention. Proceedings in Germany would have to be conducted in the German language and all documents submitted to the court would, in principle, have to be translated into German. For these reasons, it may be difficult for a U.S. investor to bring an original action in a German court predicated upon the civil liability provisions of U.S. federal securities laws against us, our directors, our senior management and the experts named in this Annual Report.

-3-
Risks related to our financial position and need for additional capital
We have a history of significant operating losses and expect to incur significant and increasing losses for the foreseeable future; we may never achieve or maintain profitability and investors may lose their entire investment
We incurred net losses of €42.7 million, €29.5 million and €45.6 million for the years ended December 31, 2023, 2022 and 2021, respectively. In addition, our accumulated deficit as of December 31, 2023, was €286.1 million.
We expect our net losses to increase as we advance vilobelimab and other product candidates into additional clinical trials, as well as larger and later-stage clinical trials. Further, we expect our net losses to increase as we advance the implementation of commercialization of GOHIBIC (vilobelimab) in the United States under the EUA while investing in start-up commercialization and marketing activities. To date, we have not commercialized any products other than for GOHIBIC (vilobelimab) for the treatment of severe COVID-19 or generated any meaningful revenues from the sale of products other than limited initial sales of GOHIBIC (vilobelimab) and absent the realization of sufficient revenues from product sales, we may never attain profitability. We have devoted substantially all of our financial resources and efforts to research and development, including preclinical studies, clinical trials and manufacturing development. Our net losses may fluctuate significantly from quarter to quarter and year to year. Net losses and negative cash flows have had, and will continue to have, an adverse effect on our shareholders’ equity and working capital.
We anticipate that our expenses might increase if and as we:
● | continue to develop and conduct clinical trials with respect to our lead product candidate, vilobelimab; |
● | continue research, preclinical and clinical development efforts for any future product candidates, including IFX002 and INF904; |
● | actively seek to identify additional research programs and additional product candidates; |
● | seek regulatory and marketing approvals for our product candidates that successfully complete clinical trials, if any; |
● | establish sales, marketing, distribution and other commercial infrastructure now and in the future to commercialize various products for which we may obtain marketing authorization or approval, if any; |
● | require the scale-up and validation of the manufacturing process and the manufacturing of larger quantities of product candidates for clinical development and, potentially, commercialization; |
● | collaborate with strategic partners to optimize the manufacturing process for vilobelimab, IFX002, INF904 and other pipeline products; |
● | maintain, expand and protect our intellectual property portfolio; |
● | hire and retain additional personnel, such as commercial, marketing, clinical, quality control and scientific personnel; and |
● | add operational, financial and management information systems and personnel, including personnel to support our product development as well as commercialization and help us comply with our obligations as a public company. |
Our ability to become and remain profitable depends on our ability to generate revenue. We do not expect to generate significant revenue unless and until we are, or any future collaborator is, able to obtain marketing authorization or approval for, and successfully commercialize, one or more of our product candidates. Successful commercialization will require achievement of key milestones, including completing clinical trials of vilobelimab and any other product candidates, obtaining marketing authorization or approval for these product candidates, manufacturing, marketing and selling those products for which we, or any of our future collaborators, may obtain marketing authorization or approval, satisfying any post-marketing requirements and obtaining reimbursement for our products from private insurance or government payors. Because of the uncertainties and risks associated with these activities, we are unable to accurately predict the timing and amount of revenues, and if or when we might achieve profitability. We and any future collaborators may never succeed in these activities and, even if we do, or any future collaborators do, we may never generate revenue that is large enough for us to achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis.
-4-
We expect our financial condition and operating results to continue to fluctuate from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control. In order to succeed, we will need to transition from a company with a research and development focus to a company capable of undertaking commercial activities. We may encounter unforeseen expenses, difficulties, complications and delays, and may not be successful in such a transition.
Our failure to become and remain profitable could depress the market price of our ordinary shares and could impair our ability to raise capital, pay dividends, expand our business, diversify our product offerings or continue our operations. If we continue to suffer losses as we have in the past, investors may not receive any return on their investment and may lose their entire investment.
We will need substantial additional funding, and if we are unable to raise capital when needed, we could be forced to delay, reduce or discontinue our product discovery and development programs or commercialization efforts
Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is a very time-consuming, expensive and uncertain process that takes years to complete. For example, for the years ended December 31, 2023 and December 31, 2022, we used €37.8 million and €33.7 million, respectively, in net cash for our operating activities, most of which were related to research and development activities. We expect our expenses to increase in connection with our ongoing activities, particularly as we initiate new clinical trials of, initiate new research and preclinical development efforts for, establish robust manufacturing processes for, establish comprehensive commercialization and marketing processes and seek marketing authorization or approval for, our current product candidates or any future product candidates, including those that we may acquire. In particular, we will incur significant expenses as we conduct our planned clinical trial program and initiate new research and preclinical development efforts. In addition, after obtaining the EUA for GOHIBIC (vilobelimab) in the United States and if we obtain marketing approval for any of our product candidates, we may incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution to the extent that such sales, marketing, manufacturing and distribution are not the responsibility of a future collaborator. Furthermore, we expect to incur significant additional costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we may be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts.
We plan to use our cash on hand primarily to fund our planned clinical trial programs, to initiate new research and preclinical development efforts, to establish commercial scale manufacturing processes and for working capital and other general corporate purposes. We will be required to expend significant funds in order to advance the development of vilobelimab in later stages of clinical development, as well as other product candidates we may seek to develop, including IFX002 and INF904. We are also evaluating vilobelimab for a number of additional indications. Any future development activities for our pipeline product candidates will depend heavily on the clinical as well as commercialization and marketing success of vilobelimab in any indication.
Our existing cash and cash equivalents will not be sufficient to fund all the efforts that we plan to undertake or to fund the completion of development of any of our product candidates. Accordingly, we will be required to obtain further funding through public or private equity offerings, debt financings, royalty-based financings, collaborations and licensing arrangements or other sources. Currently, we do not have any committed external source of funds. Adequate additional financing may not be available to us on acceptable terms, or at all. If we are unable to raise additional capital in sufficient amounts and on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of vilobelimab or any of our other product candidates or potentially discontinue operations altogether. Our failure to raise capital as and when needed could have a negative impact on our financial condition and our ability to pursue our business strategy.
-5-
We believe that our existing cash, cash equivalents and marketable securities will enable us to fund our operating expenses and capital expenditure requirements under our current business plan for at least the next 24 months. Changing circumstances, some of which may be beyond our control, could cause us to consume capital significantly faster than we anticipate, and we may need to seek additional funds sooner than planned. Our future funding requirements, both short-term and long-term, will depend on many factors, including:
● | the scope, progress, timing, costs and results of clinical trials of, and research and preclinical development efforts for, our current and future product candidates, particularly for vilobelimab; |
● | the number of future product candidates and indications that we pursue and their development requirements; |
● | the outcome, timing and costs of seeking regulatory approvals; |
● | the costs of preparation for and implementation of commercialization and commercialization activities for any of our product candidates that receive marketing authorization approval to the extent such costs are not the responsibility of any future collaborators, including the costs and timing of establishing product sales, marketing, distribution and commercial-scale manufacturing capabilities; |
● | the effect of competing technological and market developments; |
● | subject to receipt of marketing authorization or approval, revenue, if any, received from commercial sales of our current and future product candidates; |
● | our ability to enter into, and the terms and timing of, any collaborations, licensing or other arrangements; |
● | our headcount growth and associated costs as we expand our research, development, manufacturing, regulatory and commercial activities; |
● | the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our intellectual property rights including enforcing and defending intellectual property related claims; and |
● | the costs of operating as a public company. |
We have a limited operating history and history of commercializing pharmaceutical products, which may make it difficult to evaluate the prospects for our future viability
We commenced operations in 2008. Our operations to date have been limited to establishing our Company, raising capital, developing our proprietary anti-C5a and anti-C5aR technologies, identifying and testing potential product candidates and conducting clinical trials of our lead product candidate, vilobelimab and establishing a commercial scale manufacturing process for vilobelimab. In April 2023, we received the EUA for vilobelimab for the treatment of certain critically ill COVID-19 patients by the FDA. We have just started to arrange for third parties to manufacture and distribute our product at small commercial scale on our behalf. However, we have not yet demonstrated an ability to obtain full marketing approvals or conduct sales and marketing activities at large scale as necessary for successful product commercialization. Also, we are still in early stages of clinical development with our other product candidates. Accordingly, you should consider our prospects in light of the costs, uncertainties, delays and difficulties frequently encountered by companies in the early stages of development, especially clinical-stage biopharmaceutical companies such as ours. Any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully developing and commercializing pharmaceutical products.
We may encounter unforeseen expenses, difficulties, complications, delays and other known or unknown factors in achieving our business objectives. We will eventually need to transition from a company with a predominant development focus to a company capable of supporting commercial activities. We may not be successful in such a transition.
We expect our financial condition and operating results to continue to fluctuate significantly from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control. Accordingly, you should not rely upon the results of any quarterly or annual periods as indications of future operating performance.
We may be subject to risks in relation to financial grants received by the German federal government, which may result in the partial repayment of such grants
The clinical Phase III study of vilobelimab in critically ill COVID-19 patients and certain manufacturing development related activities of our product candidate vilobelimab were partly funded by the German federal government through a grant awarded to us in October 2021. The grant was structured as a reimbursement of 80% of certain pre-specified expenses related to the clinical development and manufacturing of vilobelimab. The grant period ended on June 30, 2023, as planned. In total, throughout the duration of the grant period and up to the date hereof, we received a total amount of €33.3 million. We might be subject to future audits by financial oversight authorities of the German federal government or European regulatory bodies and a failure to pass these audits in case the authorities identify non-adherence to all grant conditions could potentially lead to a retroactive revocation of parts of the funds awarded by the grant.

In addition, the German federal government has, in the case of a special public interest, a non-exclusive and transferable right to use intellectual property generated as part of the funded work. Contracts with third parties relating to the exploitation of the results of the funded work must be disclosed to the agency managing the grant on behalf of the German federal government and any such contracts with parties outside of the European Union require the prior consent of the German federal government to the extent they deviate from a commercial exploitation plan previously approved by the German federal government. Additionally, we may be required to grant third parties licenses to use such results under certain conditions. In certain scenarios, including if we come under the decisive influence of foreign investors, the funded results are exclusively or predominantly used outside Germany without the prior consent of the German federal government or if we are in breach of our obligations under the grant, the grant funding, including funding already received, can be revoked.
Exchange rate fluctuations may materially affect our results of operations and financial condition
Potential future expense and revenue may be incurred or derived from outside the European Union, particularly the United States. As a result, our business and our share price may be affected by fluctuations in foreign exchange rates between the euro and other currencies, particularly the U.S. dollar, which may also have a significant impact on our reported results of operations and cash flows from period to period. We currently do not have any exchange rate hedging arrangements in place.
We may face the risk of substantial write-downs of inventory due to the excess or obsolescence of our inventory relating to GOHIBIC (vilobelimab) due to expiration prior to sale or unsuitability for alternative use
Excess purchase of raw materials and production of products or the commitments to purchase or produce such items may result in high inventory levels that might not be commercially viable and could lead to the necessity to partially or fully write-down these items. Excess and obsolescence risks for our inventory could arise from factors such as shelf-life expiration, overstocking, or events like supply chain disruptions, manufacturing mistakes, raw material flaws which can result in errors, wastage, or delays and more. Whether such obsolescence risks materialize, ultimately depends on market demand/penetration and medical need for our products, regulatory factors such as approvals or approval withdrawals by regulatory agencies in the territories in which we intend to commercialize our product, the competitive landscape of the markets in which we operate, including the development of comparable products by our competitors as well as our ability to command prices at which we can be competitive and our own plans regarding alternative use of unfinished or finished products in our inventory for alternative purposes, such as clinical trials in additional indications. Furthermore, changes in currency exchange rates can impact the cost of imported goods and affect inventory valuations. In valuing our inventory, we make assumptions regarding these factors and update these assumptions when applicable.
1. Risks related to the discovery, development, manufacturing and commercialization of our product candidates
We are at a clinical development stage in our development efforts, our approach of targeting C5a or C5aR inhibition is novel and we may not be able to successfully develop and commercialize any product candidates
Vilobelimab is a novel therapeutic antibody and its potential therapeutic benefit is unproven, and C5a or C5aR inhibition to treat complement-mediated autoimmune and inflammatory diseases has only been partly validated. We have not yet succeeded and may never succeed in demonstrating efficacy and safety for vilobelimab in pivotal clinical trials or in obtaining marketing approval thereafter for severe COVID-19 or any other indication. The aforementioned continues to be true, although GOHIBIC(vilobelimab) has been granted the EUA by the FDA for the treatment of coronavirus disease 19, or COVID-19, in hospitalized adults when initiated within 48 hours of receiving invasive mechanical ventilation, or IMV, or extracorporeal membrane oxygenation ECMO. If we are unsuccessful in our development efforts, we may not be able to advance the development of our product candidates, commercialize products, raise capital, expand our business, or continue our operations.
-7-
We depend on the success of our product candidates, including our lead product candidate, vilobelimab, and if we are unable to obtain approval for and commercialize our product candidates for one or more indications in a timely manner, our business will be materially harmed
Our success depends on our ability to timely complete clinical trials and obtain marketing authorization or approval for, and then successfully commercialize, our product candidates, including our lead product candidate, vilobelimab, for one or more indications. Our product candidates will require additional clinical development, preclinical and manufacturing development activities, marketing approval from government regulators, commercial manufacturing, substantial investment, and significant marketing efforts before we generate any revenue from product sales. We are not permitted to market or promote any product candidates in a jurisdiction before receiving marketing authorization or approval from the relevant regulatory authority, including the FDA for marketing in the United States and EMA for marketing in Europe, and we may never receive such marketing approvals or marketing authorizations beyond the EUA for GOHIBIC (vilobelimab) granted by the FDA in April 2023. The success of our product candidates will depend on numerous factors, including:
● | raising additional funds, or entering into collaborations, necessary to complete the clinical development of and to commercialize of our product candidates; |
● | successful and timely completion of our ongoing clinical trials; |
● | initiation of successful patient enrollment and completion of additional clinical trials on a timely basis; |
● | efficacy, safety and tolerability profiles that are satisfactory to the FDA, EMA or any comparable foreign regulatory authority for marketing approval; |
● | timely receipt of marketing authorizations or approvals for our product candidates from applicable regulatory authorities; |
● | the extent of any required post-marketing approval commitments to applicable regulatory authorities; |
● | the maintenance of existing, or the establishment of new, supply arrangements with third-party drug product suppliers and manufacturers; |
● | the maintenance of existing, or the establishment of new, scaled production arrangements with third-party manufacturers to obtain finished products that are appropriately packaged for sale; |
● | obtaining and maintaining patent protection, trade secret protection and regulatory exclusivity, in the United States and elsewhere; |
● | protection of our rights in our intellectual property portfolio, including our licensed intellectual property; |
● | successful launch of commercial sales following any marketing authorization or approval; |
● | a continued acceptable safety profile following any marketing authorization or approval; |
● | commercial acceptance by patients, the medical community and third-party payors; |
● | inclusion of approved or, such as GOHIBIC (vilobelimab), authorized products in guidelines by medical bodies, including but not limited to National Institute of Health, or NIH, guidelines; |
● | inclusion of approved or, such as GOHIBIC (vilobelimab), authorized products on hospitals formulary; and |
● | our ability to compete with other therapies. |
Additionally, we cannot be sure that we can obtain necessary regulatory authorizations or approvals on a timely basis, if at all, for any of the products we are developing or manufacturing or that we can maintain necessary regulatory authorizations or approvals for our existing products, and all of the following could have a material adverse effect on our business:
● | significant delays in obtaining or failing to obtain required authorizations approvals; |
● | loss of, or changes to, previously obtained authorizations or approvals; |
● | failure to comply with existing or future regulatory requirements and; |
● | changes to manufacturing processes or manufacturing process standards following authorization or approval, or changing interpretations of these factors. |
Many of such factors remain outside of our control, and if we are unable to achieve one or more of the objectives set forth above, our business will be materially harmed.
-8-
GOHIBIC (vilobelimab) for which we received the EUA is subject to continuing regulatory oversight, which might lead to a withdrawal or revocation of the granted EUA, if the FDA considers the underlying requirements or conditions for the EUA not to be given anymore. We may incur significant losses including loss of reputation, if we the EUA for GOHIBIC (vilobelimab) is withdrawn or revoked by the FDA.
GOHIBIC (vilobelimab) for which we received the EUA for the treatment of COVID-19 in certain hospitalized adult patients, pursuant to Section 564 of the Federal Food, Drug, and Cosmetic Act (the Act) (21 U.S.C. §360bbb-3) is subject to continuing regulatory oversight, including the determination and verification of underlying requirements such as a public health emergency, or a significant potential for a public health emergency, that affects, or has a significant potential to affect, national security or the health and security of United States citizens living abroad, and that involves the virus that causes COVID-19. The granted EUA will be effective until the declaration that circumstances exist justifying the authorization of the emergency use of drugs and biological products during the COVID-19 pandemic is terminated under Section 564(b)(2) of the Act or the EUA is revoked under Section 564(g) of the Act. If the conditions or requirements for granting the EUA cease to be apparent in the future, or if reported drug safety events lead to a new situation in determining the overall pharmacovigilance of vilobelimab, the FDA may suspend, withdraw or revoke the granted EUA. Any of these events could have a material adverse effect on our business, financial condition, results of operations and prospects.
Clinical failure may occur at any stage of clinical development, and the results of our clinical trials may not support our proposed indications for our product candidates
Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and we cannot be sure that the results of later clinical trials will replicate the results of prior clinical trials and preclinical testing. Moreover, success in clinical trials in a particular indication does not ensure that a product candidate will be successful in other indications, even for the same underlying disease. A number of companies in the pharmaceutical industry, including biotechnology companies, have suffered significant setbacks in clinical trials, even after promising results in earlier preclinical studies or clinical trials or successful later-stage trials in other related indications, including in the context of controlling complement activation through C5 and C5a or C5aR inhibition. For example, while others in our industry have attempted to develop C5a-specific antibodies, there is no approved therapy inhibiting C5a. These setbacks have been caused by, among other things, preclinical findings made while clinical trials were underway and safety or efficacy observations made in clinical trials, including previously unreported adverse events as well as lack of efficacy and patient benefit as reported by clinical trial investigators. In particular, development of antibodies that target C5a rather than C5 to control complement activation is comparatively novel, and there is no approved therapy specifically targeting C5a. As a result, inhibition of C5a rather than C5, which blocks signaling to the two receptors C5aR and C5L2, may have unforeseen consequences or negative results that may lead to clinical failure or withdrawal in later stages of our product candidate development. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical and initial clinical trials for a variety of reasons, including differences in patient populations, changes in trial protocols and complexities of larger, multi-center trials among others. We may fail to complete clinical trials and/or to meet predetermined endpoints in the clinical trials, which may cause us to abandon a product candidate or an indication and may delay development of any other product candidates. Any delay in, or termination of, our clinical trials will delay the submission of the Biologics License Application, or BLA, or the EUA to the FDA, the MAA to the EMA or other similar applications with other relevant foreign regulatory authorities and, ultimately, our ability to commercialize any of our product candidates and generate revenue.
Failure to maintain compliance with FDA requirements and/or remain in alignment with FDA feedback may prevent or delay the development, marketing or manufacturing of vilobelimab for the treatment of critically ill COVID-19 patients and, potentially, of vilobelimab in ulcerative PG
Our manufacturing and laboratory facilities are periodically subject to inspection by the FDA and other governmental agencies to ensure they meet production and quality requirements. Operations at these facilities could be interrupted or halted if the FDA or another governmental agency deems the findings of such inspections unsatisfactory. Further, failure to comply with FDA or other regulatory requirements regarding the development, marketing, promotion, manufacturing and distribution of vilobelimab could result in fines, unanticipated compliance expenditures, recall or seizures of our products, total or partial suspension of production or distribution, restrictions on labeling and promotion, termination of ongoing research, disqualification of data for submission to regulatory authorities, enforcement actions, injunctions and criminal prosecution. If we do not meet applicable regulatory or quality standards, our products may be subject to recall, and under certain circumstances, we may be required to notify applicable regulatory authorities about a recall.
-9-
GOHIBIC (vilobelimab) and any other product candidates for which we receive approval or the EUA are subject to continuing regulatory oversight, and we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. We may be subject to penalties if we fail to comply with regulatory requirements.
GOHIBIC (vilobelimab) and any other product candidates for which we received or might receive approval or the EUA are subject to continuing regulatory oversight, including the review of promotional materials and additional safety information, and the applicable regulatory authority may still impose significant restrictions on the indicated uses or marketing of our product or impose ongoing requirements for potentially costly post-approval studies or post-market surveillance. Advertising and promotional materials must comply with FDA rules and are subject to FDA review, in addition to other potentially applicable federal and state laws. In other countries, advertising and promotional material may be subject to similar rules. If we fail to comply with applicable regulatory requirements following authorization or approval of any of our product candidates, a regulatory agency may:
● | issue a warning letter asserting that we are in violation of the law; |
● | seek an injunction or impose civil or criminal penalties or monetary fines; |
● | suspend or withdraw the granted EUA or regulatory approval or revoke a license; |
● | suspend any ongoing clinical studies; |
● | seize product; or |
● | refuse to allow us to enter into supply contracts, including government contracts. |
Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize any authorized or approved products and generate revenues.
Any of these events could prevent us from achieving or maintaining market acceptance of any products we may identify and develop and could have a material adverse effect on our business, financial condition, results of operations and prospects.
If clinical trials of our product candidates fail to satisfactorily demonstrate safety and efficacy to the FDA and other regulators, we, or any future collaborators, may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of these product candidates
We, and any future collaborators, are not permitted to commercialize, market, promote or sell any product candidate in the United States without obtaining marketing approval or the EUA from the FDA. Foreign regulatory authorities, such as the EMA, impose similar requirements in their respective markets. We, and any future collaborators, must complete extensive preclinical development and clinical trials to demonstrate the safety and efficacy of our product candidates in humans before we will be able to obtain these approvals.
The clinical development of our product candidates is susceptible to the risk of failure inherent at any stage of product development. It is possible that even if one or more of our product candidates has a beneficial effect, that effect will not be detected during clinical evaluation as a result of one or more of a variety of factors, including the size, duration, design, measurements, conduct or analysis of our clinical trials. In addition, many of our product candidates are in early stages of development or clinical testing. As a result, it may be years before any of our product candidates receives regulatory approval, if at all, and additional clinical trials may fail to demonstrate safety, efficacy or tolerability for our targeted indications.
-10-
Any inability to successfully complete preclinical and clinical development could result in additional costs to us or any future collaborators and impair our ability to generate revenue from product sales, regulatory and commercialization milestones and royalties. Moreover, if we or any future collaborators are required to conduct additional clinical trials or other testing of our product candidates beyond the trials and testing that we or they contemplate, if we or they are unable to successfully complete clinical trials of our product candidates or other testing or the results of these trials or tests are unfavorable, uncertain or are only modestly favorable, or there are unacceptable safety concerns associated with our product candidates, we or any future collaborators may:
● | incur additional unplanned costs, including costs relating to additional required clinical trials or preclinical testing; |
● | be delayed in obtaining marketing approval for vilobelimab or any of our other product candidates; |
● | not obtain marketing approval at all or the withdrawal or revocation of the EUA by the FDA; |
● | obtain approval for indications or patient populations that are not as broad as intended or desired; |
● | obtain approval with labeling that includes significant use or distribution restrictions or significant safety warnings, including boxed warnings; |
● | be subject to additional post-marketing testing or other requirements; or |
● | be required to remove the product from the market after obtaining marketing approval or the EUA. |
Our failure to successfully complete clinical trials of our product candidates and to demonstrate the efficacy and safety necessary to obtain regulatory approval to market any of our product candidates would significantly harm our business.
Our product candidates may cause or be perceived to cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any
Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay, denial or withdrawal of regulatory approval by the FDA or comparable foreign regulatory authorities. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. In addition, many of the patients that we enrolled in our clinical trials of vilobelimab suffer from serious pre-existing disorders. While such disorders may lead to serious adverse events, or SAEs, during trial periods that may be found to be unrelated to vilobelimab, such events may create a negative safety perception and adversely impact market acceptance of vilobelimab following any approval.
If unacceptable side effects arise in the development of our product candidates, we, the FDA or comparable foreign regulatory authorities, the Institutional Review Boards, or IRBs, or independent ethics committees at the institutions in which our studies are conducted or elsewhere, or the Data Safety Monitoring Board, or DSMB, could suspend or terminate our clinical trials or the FDA or comparable foreign regulatory authorities could order us to cease clinical trials or deny approval of our product candidates for any or all targeted indications. Side effects, whether treatment-related or not, could also affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. In addition, these side effects may not be appropriately recognized or managed by the treating medical staff. We expect to have to train medical personnel using our product candidates to understand the side effect profiles for our clinical trials and upon any commercialization of any of our product candidates. Inadequate training in recognizing or managing the potential side effects of our product candidates could result in patient injury or death. Any of these occurrences may harm our business, financial condition and prospects significantly.
Moreover, clinical trials of our product candidates are conducted in carefully defined sets of patients who have agreed to enter into clinical trials. Consequently, it is possible that our clinical trials, or those of any future collaborator, may indicate an apparent positive effect of a product candidate that is greater than the actual positive effect, if any, or alternatively fail to identify undesirable side effects. If, following approval of a product candidate, we, or others, discover that the product is less effective than previously believed or causes undesirable side effects that were not previously identified, any of the following adverse events could occur:
● | regulatory authorities may withdraw their authorization or approval of the product or seize the product; |
● | we, or any future collaborators, may need to recall the product, or be required to change the way the product is administered or conduct additional clinical trials; |
-11-
● | additional restrictions may be imposed on the marketing of, or the manufacturing processes for, the particular product; |
● | we may be subject to fines, injunctions or the imposition of civil or criminal penalties; |
● | regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication; |
● | we, or any future collaborators, may be required to create a Medication Guide outlining the risks of the previously unidentified side effects for distribution to patients; |
● | we, or any future collaborators, may be required to implement a REMS that imposes distribution and use restrictions or to conduct post-market studies or clinical trials; |
● | we, or any future collaborators, could be sued and held liable for harm caused to patients; |
● | the product may become less competitive; and |
● | our reputation may suffer. |
Any of these events could harm our business and operations and could negatively impact our share price.
Our most advanced product candidates are either chimeric or humanized antibody proteins that could cause an immune response in patients, resulting in the creation of harmful or neutralizing antibodies against these therapeutic proteins
In addition to the safety, efficacy, manufacturing and regulatory hurdles faced by our product candidates, the administration of proteins such as monoclonal antibodies that are chimeric or humanized, including our product candidates vilobelimab and IFX002, respectively, can cause an immune response, resulting in the creation of antibodies against the therapeutic protein. These anti-drug antibodies, or ADAs, can have no effect or can neutralize the effectiveness of the protein or require that higher doses be used to obtain a therapeutic effect. Whether ADAs will be created and how they react can often not be predicted from preclinical or even clinical studies, and their detection or appearance is often delayed. As a result, neutralizing antibodies may be detected at a later date or upon longer exposure of patients with our product candidates, such as following more chronic administration in longer lasting clinical trials. In some cases, detection of such neutralizing antibodies can even occur after pivotal clinical trials have been completed. Therefore, there can be no assurance that neutralizing antibodies will not be detected in future clinical trials or at a later date upon longer exposure (including after commercialization). If ADAs reduce or neutralize the effectiveness of our product candidates, the continued clinical development or receipt of marketing approval for any of our product candidates could be delayed or prevented and, even if any of our product candidates is approved, their commercial success could be limited, any of which would impair our ability to generate revenue and continue operations. Low levels of ADAs were detected in previously completed clinical studies.
Even if we complete the necessary preclinical studies and clinical trials for vilobelimab and any other product candidates, the marketing approval process including the EUA process is expensive, time consuming and uncertain and may prevent us or any future collaborators from obtaining approvals for the commercialization of some or all of our product candidates. As a result, we cannot predict when or if, and in which territories, we, or any future collaborators, will obtain marketing authorization or approval to commercialize a product candidate
The research, testing, manufacturing, labeling, approval, selling, marketing, promotion and distribution of products are subject to extensive regulation by the FDA and comparable foreign regulatory authorities. We, and any future collaborators, are not permitted to market our product candidates in the United States or in other countries until we, or they, receive approval of a BLA or the EUA from the FDA or marketing approval from applicable regulatory authorities outside the United States. Our product candidates are in various stages of development and are subject to the risks of failure inherent in drug development. We have not submitted an application for or received marketing approval for any product candidate in the United States or in any other jurisdiction. We have limited experience in conducting and managing the clinical trials necessary to obtain marketing approvals, including FDA approval of a BLA or EUA. Further, there is no prior history of regulatory approval for product candidates targeting C5a inhibition.
-12-
The process of obtaining marketing authorizations or approvals, both in the United States and elsewhere is lengthy, expensive and uncertain. It may take many years, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidates involved. Securing marketing approval, including the EUA, requires the submission of extensive preclinical and clinical data and supporting information to regulatory authorities for each therapeutic indication to establish the product candidate’s safety and efficacy. Securing marketing approval, including the EUA, also requires the submission of information about the product manufacturing process to, and inspection of manufacturing facilities by, the regulatory authorities. The FDA or other regulatory authorities may determine that our product candidates are not safe and effective, only moderately effective or have undesirable or unintended side effects, toxicities or other characteristics that preclude our obtaining marketing approval or prevent or limit commercial use. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a drug candidate’s clinical development and may vary among jurisdictions. Any marketing approval, including the EUA, we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable. For example, the EUA for the GOHIBIC (vilobelimab) has been granted for the treatment of COVID-19 in hospitalized adults when initiated within 48 hours of receiving IMV or ECMO. The FDA, EMA or any comparable foreign regulatory authorities may delay, limit or deny approval of vilobelimab for many reasons, including:
● | we may not be able to demonstrate that vilobelimab is safe and effective as a treatment for our targeted indications to the satisfaction of the FDA, the EMA or comparable foreign regulatory agencies; |
● | the FDA, EMA or comparable foreign regulatory authorities may require additional clinical trials or non-clinical studies of vilobelimab in addition to those already performed or planned, either before approval or as a post-approval commitment, which would increase our costs and prolong our development time for vilobelimab; |
● | the results of our clinical trials may not meet the level of statistical or clinical significance required by the FDA, EMA or comparable foreign regulatory authorities to obtain marketing approval; |
● | the FDA, EMA or comparable foreign regulatory authorities may disagree with the number, design, size, conduct or implementation of our clinical trials, including designated clinical endpoints; |
● | the population studied in the clinical program may not be sufficiently broad or representative to assure safety in the full population for which we seek approval; |
● | the contract research organizations, or CROs, that we retain to conduct clinical trials may take actions outside of our control that materially adversely impact our clinical trials; |
● | the FDA, EMA or comparable foreign regulatory authorities may not find the data from preclinical studies and clinical trials sufficient to demonstrate that the clinical and other benefits of vilobelimab and any other product candidates outweigh its safety risks; |
● | the FDA, EMA or comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical studies and clinical trials; |
● | the FDA, EMA or comparable foreign regulatory authorities may not accept data generated at clinical trial sites, including for non-compliance with cGCP; |
● | if our BLA, when submitted, is reviewed by an advisory committee, the FDA may have difficulties scheduling an advisory committee meeting in a timely manner or the advisory committee may recommend against approval of our application or may recommend that the FDA require, as a condition of approval, additional preclinical studies or clinical trials, limitations on approved labeling or distribution and use restrictions; |
● | the FDA, EMA or comparable foreign regulatory authorities may require development of a risk evaluation and mitigation strategy, or REMS, as a condition of approval; |
● | the FDA, EMA or comparable foreign regulatory authorities may identify deficiencies in the manufacturing processes or facilities of our third-party manufacturers, including non-compliance with current Good Manufacturing Practices, or cGMP; or |
● | the FDA, EMA or comparable foreign regulatory authorities may change their respective approval policies or adopt new regulations. |
-13-
Of the large number of drugs in development in the biopharmaceutical industry, only a small percentage result in the submission of a BLA to the FDA and even fewer are approved for commercialization. Furthermore, even if we do receive regulatory approval to market vilobelimab, any such approval may be subject to limitations on the indicated uses or patient populations for which we may market the product. Accordingly, even if we are able to obtain the requisite financing to continue to fund our development programs, we cannot assure you that vilobelimab and/or any other product candidates will be successfully developed or commercialized.
Moreover, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to the FDA or other regulatory authorities. The FDA or other regulatory authorities may conclude that a principal investigator, potentially including because of a financial relationship with us, has a conflict of interest that has affected interpretation of the study. The FDA or other regulatory authorities may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA or other regulatory authorities, as the case may be, and may ultimately lead to the denial of marketing authorization or approval of one or more of our product candidates.
Any delay in obtaining or failure to obtain required approvals could negatively impact our ability or that of any future collaborators to generate revenue from the particular product candidate, which likely would result in significant harm to our financial position and adversely impact our share price.
We depend on enrollment of patients in our clinical studies for our product candidates. If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected
We will also be required to identify and enroll a sufficient number of patients with PG, and potentially other indications, for our planned or ongoing clinical trial of vilobelimab in these indications. Some of these are rare disease indications or indication with a relatively small patient population. Trial participant enrollment could be limited in future trials given that many potential participants may be ineligible because they are already undergoing treatment with approved medications or are participating in other clinical trials.
Patient enrollment is affected by other factors, including:
● | severity of the disease under investigation; |
● | design of the clinical trial protocol; |
● | size and nature of the patient population; |
● | eligibility criteria for the trial in question; |
● | perceived risks and benefits of the product candidate under trial; |
● | perceived safety and tolerability of the product candidate; |
● | proximity and availability of clinical trial sites for prospective patients; |
● | availability of competing therapies and clinical trials; |
● | clinicians’ and patients’ perceptions as to the potential advantages of the drug being studied in relation to other available therapies, including standard-of-care and any new drugs that may be approved for the indications we are investigating; |
● | efforts to facilitate timely enrollment in clinical trials; |
● | patient referral practices of physicians; and |
● | our ability to monitor patients adequately during and after treatment. |
Further, there are only a limited number of specialist physicians who treat patients with these diseases and major clinical centers are concentrated in a few geographic regions. We also may encounter difficulties in identifying and enrolling such patients with a stage of disease appropriate for our ongoing or future clinical trials. In addition, the process of finding and diagnosing patients may prove costly. Our inability to enroll a sufficient number of patients for any of our clinical trials, if any, would result in significant delays or may require us to abandon one or more clinical trials.
We have experienced slower recruitment than anticipated in the clinical trials of vilobelimab in severe COVID-19, PG and cSCC, because of other compounds in clinical development for the same patient population, low disease prevalence, difficulties in diagnosis or due to restrictions at clinical trial sites in light of the COVID-19 pandemic. Further delays in the completion of any clinical trials will increase our costs, slow down our product candidate development and delay or potentially jeopardize our ability to commence marketing and generate revenue. In addition, we may not be able to initiate or continue clinical trials required by the FDA, EMA or other foreign regulatory agencies for vilobelimab or any of our other product candidates that we pursue if we are unable to locate and enroll a sufficient number of eligible patients to participate in these clinical trials.
-14-
Even if one of our product candidates receives marketing approval, including the EUA, it may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success, in which case we may not generate significant revenues or become profitable
Even if our other product candidates are approved by the appropriate regulatory authorities for marketing and sale or receives the EUA, they may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. As a general proposition, physicians are often reluctant to switch their patients from existing therapies, such as for the treatment of cSCC, even when new and potentially more effective or convenient treatments enter the market. Further, patients often acclimate to existing therapies and do not want to switch therapies unless their physicians recommend doing so or they are required to do so due to lack of reimbursement for existing therapies. Further, we may face a lack of acceptance by the physician community of the efficacy of targeting C5a to inhibit terminal complement activation compared to targeting C5, which is well established in clinical practice (such as eculizumab). In addition, vilobelimab may not be accepted by physicians or patients if we cannot demonstrate, or if vilobelimab is perceived as not having, strong duration of effect, including compared to existing treatments. The duration of effect of vilobelimab has only been studied prospectively for durations less than the expected duration of any pivotal Phase III clinical trials. It is possible that the effects seen in shorter term clinical trials will not be replicated at later time points or in larger clinical trials. Further, even if we are able to demonstrate our product candidates’ safety and efficacy to the FDA and other regulators, safety concerns in the medical community may hinder market acceptance.
Efforts to educate the medical community and third-party payors on the benefits of our product candidates may require significant resources, including management time and financial resources, and may not be successful. If any of our product candidates is approved but does not achieve an adequate level of market acceptance, we may not generate significant revenues and we may not become profitable. The degree of market acceptance of our product candidates, if approved for commercial sale, will depend on a number of factors, including:
● | the efficacy and safety of the product; |
● | the potential advantages of the product compared to competitive therapies, notwithstanding success in meeting or exceeding clinical trial endpoints; |
● | the prevalence and severity of any side effects; |
● | whether the product is designated under physician treatment guidelines as a first-, second- or third-line therapy; |
● | our ability, or the ability of any future collaborators, to offer the product for sale at competitive prices; |
● | the product’s convenience and ease of administration compared to alternative treatments; |
● | the willingness of the target patient population to try, and of physicians to prescribe, the product; |
● | limitations or warnings, including distribution or use restrictions contained in the product’s approved labeling; |
● | the strength of sales, marketing and distribution support; |
● | changes in the standard of care for the targeted indications for the product; and |
● | availability and amount of coverage and reimbursement from government payors, managed care plans and other third-party payors. |
The failure of any of our product candidates, if authorized or approved, to find market acceptance would harm our business and could require us to seek additional financing.
-15-
Even if we, or any future collaborators, are able to commercialize any product candidate that we, or they, develop, the product may become subject to unfavorable pricing regulations or third-party payor coverage and reimbursement policies, any of which could harm our business
Patients who are provided medical treatment for their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Therefore, our ability, and the ability of any future collaborators, to commercialize any of our product candidates will depend in part on the extent to which coverage and reimbursement for these products and related treatments will be available from third-party payors including government health administration authorities and public or private health coverage insurers. Third-party payors decide which medications they will cover and establish reimbursement levels. We cannot be certain that reimbursement will be available for vilobelimab or any of our product candidates. Also, we cannot be certain that less fulsome reimbursement policies will not reduce the demand for, or the price we can charge for, our products, if approved. The insurance coverage and reimbursement status of newly approved products for orphan diseases is particularly uncertain and failure to obtain or maintain adequate coverage and reimbursement for vilobelimab or any other product candidates could limit our ability to generate revenue.
If coverage and reimbursement are not available, or reimbursement is available only to limited levels, we, or any future collaborators, may not be able to successfully commercialize our product candidates. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us, or any future collaborators, to establish or maintain pricing sufficient to realize a sufficient return on our or their investments. In the United States, no uniform policy of coverage and reimbursement for products exists among third-party payors and coverage and reimbursement for products can differ significantly from payor to payor. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance.
There is significant uncertainty related to third-party payor coverage and reimbursement of newly approved drugs. Marketing approvals, pricing and reimbursement for new drug products vary widely from country to country. Some countries require approval of the sales price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we, or any future collaborators, might obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay commercial launch of the product, possibly for lengthy time periods, which may negatively impact the revenues we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability or the ability of any future collaborators to recoup our or their investment in one or more product candidates, even if our product candidates obtain marketing approval.
The healthcare industry is acutely focused on cost containment, both in the United States and elsewhere. Government authorities and other third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications, which could affect our ability or that of any future collaborators to sell our product candidates profitably. These payors may not view our products, if any, as cost-effective, and coverage and reimbursement may not be available to our customers, or those of any future collaborators, or may not be sufficient to allow our products, if any, to be marketed on a competitive basis. Cost-control initiatives or other policy measures by government authorities could cause us, or any future collaborators, to decrease the price we, or they, might establish for products, which could result in lower than anticipated product revenues. If the prices for our products, if any, decrease or if governmental and other third-party payors do not provide coverage or adequate reimbursement, our prospects for revenue and profitability will suffer.
There may also be delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the indications for which the drug is authorized or approved by the FDA or comparable foreign regulatory authorities. Moreover, eligibility for reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Reimbursement rates may vary, by way of example, according to the use of the product and the clinical setting in which it is used. Reimbursement rates may also be based on reimbursement levels already set for lower cost drugs or may be incorporated into existing payments for other services.
In addition, increasingly, third-party payors are requiring higher levels of evidence of the benefits and clinical outcomes of new technologies and are challenging the prices charged. We cannot be sure that reimbursement coverage will be available for any product candidate that we, or any future collaborator, commercialize and, if available, that the reimbursement rates will be adequate. Further, the net reimbursement for drug products may be subject to additional reductions if there are changes to laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. An inability to promptly obtain coverage and adequate payment rates from both government-funded and private payors for any of our product candidates for which we, or any future collaborator, obtain marketing authorization or approval could significantly harm our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.
-16-
If we are unable to develop our sales, marketing and distribution capability on our own or through collaborations with marketing partners, we will not be successful in commercializing our product candidates
We have limited marketing, sales or distribution capabilities and experience within our organization. If any of our product candidates is authorized or approved, we either have to establish a sales and marketing organization with technical expertise and supporting distribution capabilities to commercialize any such candidate, or to outsource this function to a third party. These activities were initiated in 2023 regarding the FDA’s EUA for GOHIBIC (vilobelimab) in the United States. Either of these options would be expensive and time consuming. Some or all of these costs may be incurred in advance of any approval of our product candidates, including our lead candidate vilobelimab. In addition, we may not be able to hire a sales force in the United States, Europe or other target market that is sufficient in size or has adequate expertise in the medical markets that we intend to target. These risks may be particularly pronounced due to our focus on severe COVID-19, as well as additional focus on PG, each of which are disease areas with relatively small patient populations. Any failure or delay in the development of our or third parties’ internal sales, marketing and distribution capabilities would adversely impact the commercialization of vilobelimab and other future product candidates.
With respect to our existing and future product candidates, we may choose to collaborate with third parties that have direct sales forces and established distribution systems, either to augment or to serve as an alternative to our own sales force and distribution systems. Our product revenue may be lower than if we directly marketed or sold any approved products. In addition, any revenue we receive will depend in whole or in part upon the efforts of these third parties, which may not be successful and are generally not within our control. If we are unable to enter into these arrangements on acceptable terms or at all, we may not be able to successfully commercialize any authorized or approved products. If we are not successful in commercializing any authorized or approved products, our future product revenue will suffer and we may incur significant additional losses.
We may be subject to risks in relation to shelf-life expiration of drug product for GOHIBIC (vilobelimab), including but not limited to substantial write-offs in the balance sheet
Our finished drug product for GOHIBIC (vilobelimab) for use of commercial purposes under the granted the EUA in the United States is subject to limited shelf-life periods. If we fail to use such finished drug product for the intended use prior to its shelf-life expiration, such drug product will have to be destroyed accordingly, which might cause additional and substantial costs and expense as well as which might lead to substantial write-offs of destroyed drug product.
We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success
We have limited financial and managerial resources, and therefore we intend to focus on developing product candidates for specific indications that we identify as most likely to succeed, in terms of both their potential for marketing authorization, approval and commercialization. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications that may prove to have greater commercial potential.
Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable product candidates. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to the product candidate.
-17-
Clinical development involves a lengthy and expensive process, with an uncertain outcome. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of vilobelimab or any other product candidate we may develop
The risk of failure for vilobelimab and any other product candidates we may develop such as INF904 is high. It is impossible to predict when or if vilobelimab will prove to be effective and safe in humans or will receive full regulatory approval for the treatment of severe COVID-19 or PG indication, or other indications. Additionally, before regulatory authorities grant marketing approval or the EUA for vilobelimab, for any future indications, or any future product candidate that we seek to develop, we will be required to complete our ongoing extensive clinical trials to demonstrate safety and efficacy in humans. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is inherently uncertain as to outcome. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their drugs.
We may experience numerous unforeseen events during or as a result of the regulatory authorization and/or approval process that could delay or prevent our ability to receive marketing approval or the EUA from regulators or commercialize vilobelimab or any future product candidate, including:
● | regulators or institutional review boards may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site; |
● | clinical trials of our product candidates may produce negative or inconclusive results, including failure to demonstrate statistical significance, and we may decide, or regulators may require us, to conduct additional clinical trials or abandon drug development programs; |
● | our product candidates may have undesirable side effects or other unexpected characteristics, causing us or our investigators, regulators, ethics committees or institutional review boards to suspend or terminate the trials; |
● | our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all; and |
● | regulators, ethics committees or institutional review boards may require that we or our investigators suspend or terminate clinical development for various reasons, including noncompliance with regulatory requirements or a finding that the participants are being exposed to unacceptable health risks. |
We could also encounter delays if a clinical trial is suspended or terminated by us, by an overseeing ethics committee, by the institutional review boards of the institutions in which such trials are being conducted, by the data safety monitoring board for such trial or by the FDA or other regulatory authorities. Such authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. If we experience delays in the completion of, or termination of, any clinical trial of our product candidates, the commercial prospects of our product candidates will be harmed, and our ability to generate drug revenues from any of these product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval process and jeopardize our ability to commence drug sales and generate revenues. Any of these occurrences may harm our business, financial condition and prospects significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval.
-18-
Our product development costs will further increase if we experience delays in testing or marketing approvals. Significant clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow our competitors to bring drugs to market before we do and impair our ability to successfully commercialize our product candidates. We are evaluating applications for orphan drug or breakthrough therapy designation for vilobelimab in various indications, but we may be unable to obtain any such designation or to maintain the benefits associated with orphan drug status, including market exclusivity, even if that designation is granted
We are evaluating applications for orphan drug or breakthrough therapy designation for vilobelimab in some indications, and we may seek orphan drug designation for other preclinical product candidates in our pipeline or that we may develop. In the United States and other countries, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and user-fee waivers. After the FDA or other foreign regulatory agency grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the FDA review and approval process. Breakthrough therapy designation is a process designed to expedite the development and review of drugs that are intended to treat a serious condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint. Breakthrough therapy designation may make us eligible for intensive guidance by the FDA on an efficient drug development program and organizational commitment involving senior FDA managers, among others. Although we are evaluating applications for orphan drug or breakthrough therapy designation in some indications, there can be no assurance that we will obtain such designations. Moreover, obtaining orphan drug or breakthrough therapy designation for one indication does not mean we will be able to obtain such designation for another indication.
If a product that has orphan drug designation from the FDA subsequently receives the first FDA approval for a particular active ingredient for the disease for which it has such designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications, including a BLA, to market the same drug for the same indication for seven years, except in limited circumstances such as if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Similarly, the FDA can subsequently approve a drug with the same active moiety for the same condition during the exclusivity period if the FDA concludes that the later drug is clinically superior, meaning the later drug is safer, more effective, or makes a major contribution to patient care. Even if we were to obtain orphan drug designation for vilobelimab from the FDA, we may not be the first to obtain marketing approval for any particular orphan indication due to the uncertainties associated with developing pharmaceutical products, and thus approval of vilobelimab could be blocked for seven years if another company obtains approval and orphan drug exclusivity for the same drug and same condition before us. If we do obtain exclusive marketing rights in the United States, they may be limited if we seek approval for an indication broader than the orphan designated indication and may be lost if the FDA later determines that the request for designation was materially defective or if we are unable to assure sufficient quantities of the product to meet the needs of the relevant patients. Further, exclusivity may not effectively protect the product from competition because different drugs with different active moieties can be approved for the same condition, the same drugs can be approved for different indications and might then be used off-label in our approved indication, and different drugs for the same condition may already be approved and commercially available.
Even if we obtain FDA authorization or approval of vilobelimab or any of our other product candidates, we may never obtain authorization or approval or commercialize our products outside of the United States
In order to market any approved products outside of the United States, we must establish and comply with numerous and varying regulatory requirements of other countries regarding clinical trial design, safety and efficacy. If approved by the relevant governmental authorities, we expect to market vilobelimab for the treatment of COVID-19 and other indications in Europe and jurisdictions outside the United States, in part due to the relatively larger patient population that exists in Europe as compared to that in the United States. Clinical trials conducted in one country may not be accepted by regulatory authorities in other countries, and regulatory approval in one country does not mean that regulatory approval will be obtained in any other country. Approval procedures vary among countries and can involve additional product testing and validation and additional administrative review periods. Seeking foreign regulatory approvals could result in significant delays, difficulties and costs for us and may require additional preclinical studies or clinical trials, which would be costly and time consuming and could delay or prevent introduction of vilobelimab or any of our other product candidates in those countries.
-19-
In addition, we expect to be subject to a variety of risks related to operating in other countries if we obtain the necessary approvals, including:
● | differing regulatory requirements in countries outside the United States; |
● | the potential for so-called parallel importing (i.e., when a local seller, faced with high or higher local prices, opts to import goods from a foreign market (with low or lower prices) rather than buying them locally); |
● | unexpected changes in tariffs, trade barriers, price and exchange controls and other regulatory requirements; |
● | economic weakness, including inflation, or political instability in particular foreign economies and markets; |
● | foreign reimbursement, pricing and insurance regimes; |
● | compliance with tax, employment, immigration and labor laws for employees living or traveling outside the United States; |
● | foreign taxes, including withholding of payroll taxes; |
● | foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incident to doing business in another country; |
● | difficulties staffing and managing foreign operations; |
● | workforce uncertainty in countries where labor unrest is more common than in the United States; |
● | potential liability under the Foreign Corrupt Practices Act of 1977 or comparable foreign regulations; |
● | challenges enforcing our contractual and intellectual property rights, especially in countries that do not protect intellectual property rights to the same extent as in the United States; |
● | production shortages resulting from any events affecting raw material supply or manufacturing capabilities as well as supply chain disruptions outside the United States; and |
● | business interruptions, including as a results of geopolitical uncertainty and instability (including related to the Russia-Ukraine conflict). |
If we or our partners fail to comply with regulatory requirements or to obtain and maintain required approvals, our target market will be reduced, including if we are unable to market vilobelimab in Europe or elsewhere, and our ability to realize the full market potential of our product candidates will be harmed.
We are subject to extensive government regulation and the failure to comply with these regulations may have a material adverse effect on our operations and business
Both before and after approval of any product, we and our suppliers, contract manufacturers and clinical investigators are subject to extensive regulation by governmental authorities in the United States and other countries, covering, among other things, testing, manufacturing, quality control, clinical trials, post-marketing studies, labeling, advertising, promotion, distribution, import and export, governmental pricing, price reporting and rebate requirements. Failure to comply with applicable requirements could result in one or more of the following actions: warning letters; unanticipated expenditures; delays in approval or refusal to approve a product candidate; product recall or seizure; interruption of manufacturing or clinical trials; operating or marketing restrictions; injunctions; criminal prosecution and civil or criminal penalties including fines and other monetary penalties; adverse publicity; and disruptions to our business. Further, government investigations into potential violations of these laws would require us to expend considerable resources and face adverse publicity and the potential disruption of our business even if we are ultimately found not to have committed a violation.
Obtaining FDA, EMA or other regulatory agency authorization or approval of our product candidates requires substantial time, effort and financial resources and may be subject to both expected and unforeseen delays, and there can be no assurance that any approval will be granted on any of our product candidates on a timely basis, if at all. The FDA, EMA or other regulatory agencies may decide that our data are insufficient for authorization or approval of our product candidates and require additional preclinical, clinical or other studies or additional work related to chemistry, manufacturing and controls, or CMC. If we are required to conduct additional trials or to conduct other testing of our product candidates beyond that which we contemplate for regulatory approval, if we are unable to complete successfully our clinical trials or other testing or if the results of these and other trials or tests fail to demonstrate efficacy or raise safety concerns, we may face substantial additional expenses, be delayed in obtaining marketing approval for our product candidates or may never obtain marketing approval.
-20-
We are also required to comply with extensive governmental regulatory requirements after a product has received marketing authorization or approval. Governing regulatory authorities may require post-marketing studies that may negatively impact the commercial viability of a product. Once on the market, a product may become associated with previously undetected adverse effects and/or may develop manufacturing difficulties. As a result of any of these or other problems, a product’s regulatory approval could be withdrawn, which could harm our business and operating results.
Our current and future relationships with third-party payors, health care professionals and customers in the United States and elsewhere may be subject, directly or indirectly, to applicable anti-kickback, fraud and abuse, false claims, physician payment transparency, health information privacy and security and other healthcare laws and regulations, which could expose us to significant penalties
Healthcare providers, physicians and third-party payors in the United States and elsewhere will play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Our current and future arrangements with health care professionals, third-party payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations, including the federal Anti-Kickback Statute and the federal civil False Claims Act, that may constrain the business or financial arrangements and relationships through which we conduct clinical research, sell, market and distribute any drugs for which we obtain marketing approval. In addition, we may be subject to transparency laws and patient privacy regulation in the United States and other jurisdictions in which we conduct our business. The applicable federal, state and foreign healthcare laws and regulations that may affect our ability to operate include the following:
● | the federal Anti-Kickback Statute, which prohibits, among other things, persons and entities from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made under federal and state healthcare programs, such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation. Further, several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the Anti-Kickback Statute has been violated. Moreover, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act; |
● | federal civil and criminal false claims laws, including the federal civil False Claims Act (that can be enforced through civil whistleblower or qui tam actions), and the civil monetary penalties law, which impose criminal and civil penalties against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, including the Medicare and Medicaid programs, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government; |
● | the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability for, among other things, executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it to have committed a violation; |
● | HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their respective implementing regulations, which impose obligations on covered healthcare providers, health plans, and healthcare clearinghouses, as well as their business associates that create, receive, maintain or transmit individually identifiable health information for or on behalf of a covered entity, with respect to safeguarding the privacy, security and transmission of individually identifiable health information; |
-21-
● | the Physician Payments Sunshine Act, created under Section 6002 of Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively the Affordable Care Act, and its implementing regulations, which requires specified manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, to report annually to the Centers for Medicare & Medicaid Services, or CMS, information related to payments or other “transfers of value” made to physicians, which is defined to include doctors, dentists, optometrists, podiatrists and chiropractors, and teaching hospitals and applicable manufacturers to report annually to CMS ownership and investment interests held by physicians and their immediate family members by the 90th day of each calendar year. All such reported information is publicly available; and |
● | analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers; state and foreign laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare providers; state and foreign laws that require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; and state and foreign laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts. |
Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations may involve substantial costs. It is possible that governmental authorities will conclude that our business practices, including our relationships with physicians and other healthcare providers, some of whom may recommend, purchase or prescribe vilobelimab, if approved, may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations.
If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, including damages, fines, disgorgement, individual imprisonment, exclusion from participation in government healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws and the curtailment or restructuring of our operations, which could have a material adverse effect on our business. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found not to be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from participation in government healthcare programs, which could also materially affect our business.
Enacted and future legislation may increase the difficulty and cost for us to obtain marketing authorization or approval of and commercialize vilobelimab and affect the prices we may obtain
In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of vilobelimab, restrict or regulate post-approval activities and affect our ability to profitably sell any product candidates for which we obtain marketing authorization or approval.
Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives such as the Affordable Care Act in 2010, a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. In the coming years, additional legislative and regulatory changes could be made to governmental health programs that could significantly impact pharmaceutical companies and the success of our drug candidate.
In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. These changes included aggregate reductions to Medicare payments to providers of 2% per fiscal year effective April 1, 2013, and, due to subsequent legislative amendments to the statute, will stay in effect through 2025, unless additional congressional action is taken. The American Taxpayer Relief Act of 2012, further reduced, among other things, Medicare payments to several providers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on customers for our drugs, if approved, and, accordingly, our financial operations.
-22-
Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our drugs.
Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for drugs. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of vilobelimab, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent drug labeling and post-marketing testing and other requirements.
Even if we, or any future collaborators, obtain marketing approvals or the EUA for our product candidates, the terms of approvals and ongoing regulation of our products may limit how we manufacture and market our products, which could impair our ability to generate revenue
Once marketing approval or the EUA has been granted, an approved product and its manufacturer and marketer are subject to ongoing review and extensive regulation. We, and any future collaborators, must therefore comply with requirements concerning advertising and promotion for any of our product candidates for which we or they obtain marketing approval. Promotional communications with respect to prescription drugs are subject to a variety of legal and regulatory restrictions and must be consistent with the information in the product’s approved labeling. Thus, we and any future collaborators will not be able to promote any products we develop for indications or uses for which they are not approved.
In addition, manufacturers of authorized and approved products and those manufacturers’ facilities are required to comply with extensive FDA requirements, including ensuring that quality control and manufacturing procedures conform to cGMPs, which include requirements relating to quality control and quality assurance as well as the corresponding maintenance of records and documentation and reporting requirements. We, our contract manufacturers, any future collaborators and their contract manufacturers could be subject to periodic unannounced inspections by the FDA to monitor and ensure compliance with cGMPs.
Accordingly, assuming we, or any future collaborators, receive marketing approval for one or more of our product candidates, we, and any future collaborators, and our and their contract manufacturers will continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production, product surveillance and quality control.
The manufacturing and distribution of GOHIBIC (vilobelimab) is subject to a number of risks that could harm our reputation, business, financial condition and operating results.
The manufacturing processes of GOHIBIC(vilobelimab) is complex. We may encounter manufacturing difficulties, including difficulties related to product storage and shelf-life. Such difficulties could result from the complexities of manufacturing product batches at a larger scale, equipment failure, availability of excipients and other product components/ingredients (including related to choice and quality of raw materials), analytical testing technology and product instability. Specifically, insufficient product stability or shelf-life of GOHIBIC (vilobelimab) or its components could materially limit or delay our or our collaborators’ ability to distribute and commercialize GOHIBIC(vilobelimab) at the current price or at all. Further, if GOHIBIC(vilobelimab) becomes subject to a product recall, including as the result of manufacturing errors, design/labeling defects or other deficiencies, our reputation would be adversely affected.
GOHIBIC (vilobelimab) is a “cold-chain product” that must be shipped and stored at cold temperatures. We could lose supply of GOHIBIC (vilobelimab) due to distribution difficulties, including generally related supply chain management (e.g., shelf-life expiration) and specifically related to shipping and storing GOHBIC(vilobelimab) at cold temperatures. If so, we could incur additional manufacturing costs in order to supply required quantities to U.S. hospitals under the EUA.
Any such manufacturing and distribution difficulties may harm our reputation, business, financial condition and operating results.
-23-
Governments, including those outside the United States, tend to impose strict price controls, which may adversely affect our revenues, if any
In many countries, such as countries of the European Union, the pricing of prescription pharmaceuticals is subject to varying price control mechanisms, often as part of national health systems. Other countries allow companies to fix their own prices for medical products but monitor and control company profits. Pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we, or any future collaborators, may be required to conduct a clinical trial that compares the cost-effectiveness of our product to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be harmed. Additional price controls or other changes in pricing regulation could restrict the amount that we are able to charge for our product candidates, and we believe the increasing emphasis on cost-containment initiatives in the European Union has and will continue to put pressure on the pricing and usage of our product candidates. As a result, given the relatively smaller target markets for severe COVID-19 and PG, any reduced reimbursement for such product candidates may be insufficient for us to generate commercially reasonable revenue and profits and would adversely affect our financial condition and results of operations.
Any of our product candidates for which we, or any future collaborators, obtain marketing approval or the EUA in the future could be subject to post-marketing restrictions or withdrawal from the market and we, or any future collaborators, may be subject to substantial penalties if we, or they, fail to comply with regulatory requirements or if we, or they, experience unanticipated problems with our products following approval or the EUA
Any of our product candidates for which we, or any future collaborators, obtain marketing approval or the EUA, as well as the manufacturing processes, post-approval studies and measures, labeling, advertising and promotional activities for such product, among other things, will be subject to ongoing requirements of and review by the FDA, the EMA and other regulatory authorities. These requirements include submissions of safety and other post-marketing information and reports, registration and listing requirements, requirements relating to manufacturing, quality control, quality assurance and corresponding maintenance of records and documents, requirements regarding the distribution of samples to physicians and recordkeeping. Even if marketing approval or the EUA of a product candidate is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to the conditions of approval, including the requirement to implement a REMS.
The FDA, the EMA and other regulatory authorities may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of a product. The FDA and other agencies, including the Department of Justice, closely regulate and monitor the post-approval marketing and promotion of products to ensure that they are manufactured, marketed and distributed only for the authorized or approved indications and in accordance with the provisions of the approved labeling. The FDA imposes stringent restrictions on manufacturers’ communications regarding off-label use and if we, or any future collaborators, do not market any of our product candidates for which we, or they, receive marketing approval for only their approved indications, we, or they, may be subject to warnings or enforcement action for off-label marketing. Violation of the FDCA and other statutes relating to the promotion and advertising of prescription drugs may lead to investigations or allegations of violations of federal and state health care fraud and abuse laws and state consumer protection laws, including the False Claims Act.
In addition, later discovery of previously unknown adverse events or other problems with our products or their manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may yield various results, including:
● | restrictions on the manufacturing of such products; |
● | restrictions on the labeling or marketing of such products; |
● | restrictions on product distribution or use; |
● | requirements to conduct post-marketing studies or clinical trials; |
● | warning letters or untitled letters; |
-24-
● | withdrawal of the products from the market; |
● | refusal to approve pending applications or supplements to approved applications that we submit; |
● | recall of products; |
● | restrictions on coverage by third-party payors; |
● | fines, restitution or disgorgement of profits or revenues; |
● | suspension or withdrawal of marketing approvals, including the EUA; |
● | refusal to permit the import or export of products; |
● | product seizure; or |
● | injunctions or the imposition of civil or criminal penalties. |
Our ability to successfully commercialize and generate revenue from sales of GOHIBIC (vilobelimab) is subject to a number of risks that could harm our business, financial condition and operating results.
Our ability to successfully commercialize GOHIBIC (vilobelimab) is subject to a number of risks that could impact our business, financial condition and operating results. Specifically, our ability to generate revenue from sales of GOHIBIC (vilobelimab) is uncertain, including due to the market opportunity for, and interest and perception in, GOHIBIC (vilobelimab). In particular, given fluctuations in the number of patients developing severe symptoms from COVID-19 infections, the size of the addressable patient population and, thus, the market opportunity for GOHIBIC (vilobelimab) is uncertain and may shrink over time. In addition, since GOHIBIC (vilobelimab) has the EUA, but not the FDA approval, sales of GOHIBIC (vilobelimab) depend on whether healthcare providers at U.S. hospitals are interested in and receptive to providing GOHIBIC (vilobelimab) as a treatment for COVID-19. Specifically, if GOHIBIC (vilobelimab) is not included in the treatment guidelines issued by medical institutions and other third-party medical/healthcare organizations, such as the NIH, or if such institutions and organizations do not recommend GOHIBIC (vilobelimab), hospitals may not be willing to make GOHIBIC (vilobelimab) available for treatment of patients. For example, the NIH guidelines stipulate that there is insufficient evidence to recommend either for or against the use of GOHIBIC (vilobelimab) for the treatment of critically ill COVID-19 patients. This neutral NIH guideline has negatively affected the commercial adoption of GOHIBIC (vilobelimab) as many healthcare providers, particularly hospitals, rely on NIH treatment guidelines when deciding to include prescription drugs to their formularies allowing for the placement of product orders by hospital staff. Ultimately, if we are unable to successfully commercialize and generate revenue from sales of GOHIBIC (vilobelimab), our business, financial condition and operating results could be adversely affected.
2. Risks related to our dependence on third parties
We rely on third parties to conduct our clinical trials. If they do not perform satisfactorily, our business could be harmed
We do not independently conduct clinical trials of any of our product candidates. We rely on third parties, such as CROs, clinical data management organizations, third-party consultants, medical institutions and clinical investigators, to conduct these clinical trials and expect to rely on these third-parties to conduct clinical trials of any other product candidate that we develop. Any of these third parties may terminate their engagements with us under certain circumstances. We may not be able to enter into alternative arrangements or do so on commercially reasonable terms. In addition, there is a natural transition period when a new CRO begins work. As a result, delays would likely occur, which could negatively impact our ability to meet our expected clinical development timelines and harm our business, financial condition and prospects.
-25-
Further, although our reliance on these third parties for clinical development activities limits our control over these activities, we remain responsible for ensuring that each of our trials is conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards. For example, notwithstanding the obligations of a CRO for a trial of one of our product candidates, we remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA, the EMA and potentially other regulatory agencies of different countries require us to comply with requirements, commonly referred to as current Good Clinical Practices, or cGCP, for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. The FDA and regulatory agencies inside the European Union and other regulatory agencies enforce these cGCP regulations through periodic inspections of trial sponsors, principal investigators, clinical trial sites and IRBs. If we or our third-party contractors fail to comply with applicable cGCP regulations, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or other regulatory agencies may require us to perform additional clinical trials before approving our product candidates, which would delay the marketing approval process. We cannot be certain that, upon inspection, the FDA or other regulatory agencies will determine that any of our clinical trials comply with cGCP. We are also required to register clinical trials and post the results of completed clinical trials on a government-sponsored database, such as ClinicalTrials.gov in the United States, within certain timeframes. The same requirement applies to clinical trials outside the United States, such as EudraCT.ema.europa.eu in Europe. Failure to do so can result in fines, adverse publicity and civil and criminal sanctions.
Furthermore, the third parties conducting clinical trials on our behalf are not our employees, and except for remedies available to us under our agreements with such contractors, we cannot control whether or not they devote sufficient time, skill and resources to our ongoing development programs. These contractors may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials or other drug development activities, which could impede their ability to devote appropriate time to our clinical programs. If these third parties, including clinical investigators, do not successfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, we may not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates. If that occurs, we will not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates. In such an event, our financial results and the commercial prospects for any product candidates that we seek to develop could be harmed, our costs could increase and our ability to generate revenues could be delayed, impaired or foreclosed.
Our reliance on foreign third-party manufacturers and suppliers increases our risk of obtaining adequate, timely and cost-effective product candidates and products
Foreign manufacturing is subject to a number of risks, including political and economic disruptions, the imposition of tariffs, quotas and other import or export controls, changes in governmental policies and geopolitical uncertainty and instability, which have created market volatility. In particular, we rely on third-party manufacturer located in China and elsewhere for supply of vilobelimab. We outsource all manufacturing of our product candidates and products to third parties while conducting certain quality control tests in-house. The supply chain and manufacturing in China may, also as a result of the current global pandemic as well as the global political situation, significantly impact our operations.
We engage a third-party manufacturer located in China for the clinical supply of the final drug product formulation of vilobelimab. There is no assurance that we would be able to timely secure needed alternative supply arrangements on satisfactory terms, or at all, if needed. Our reliance on our manufacturer and our failure to secure alternative supply arrangements as needed could have a material adverse effect on our ability to complete the development of our product candidates or, to commercialize them, if approved. There may be difficulties in scaling up to commercial quantities or optimization of processes and formulation of vilobelimab and the costs of manufacturing could be prohibitive.
Even if we were able to establish and maintain arrangements with other third-party manufacturers, reliance on third-party manufacturers generally entails additional risks beyond our control, including:
● | reliance on third parties for manufacturing process development, regulatory compliance and quality assurance; |
● | reliance on third parties for storage and safeguarding of substantially all inventory; |
● | costs and validation of new equipment and facilities required for additional scale-up or optimization of processes; |
● | failure to comply with cGMP and similar foreign standards; |
● | limitations on supply availability resulting from capacity and scheduling constraints of third parties; |
● | lack of qualified backup suppliers for those components that are purchased from a sole or single source supplier; |
● | closures and restrictions on critical facilities resulting from public health crises; |
-26-
● | the ability to freely import clinical trial material and potentially marketing material manufactured at our third-party manufacturer in China into the countries in which the clinical trials are being conducted or product potentially to be sold; |
● | the possible breach of manufacturing agreements by third parties because of factors beyond our control; and |
● | the possible termination or non-renewal of the manufacturing agreements by the third party, at a time that is costly or inconvenient to us, and our ability to obtain alternative supply. |
If we do not maintain our key manufacturing relationships, we may fail to find replacement manufacturers or develop our own manufacturing capabilities, which could delay or impair our ability to obtain regulatory approval for our products. If we do find replacement manufacturers, we may not be able to enter into agreements with them on terms and conditions favorable to us and there could be a substantial delay before new facilities could be qualified and registered with the FDA and other foreign regulatory authorities. In addition, a change of the manufacturing facility contains inherent risks and is generally viewed as a major change in the manufacturing process such that comparability studies have to be conducted to assure comparability between the before established manufacturing process and the newly established manufacturing process potentially causing delays in the drug product supply or, in case of a non-comparability of the manufactured drug product, warrant further additional pre-clinical and or clinical studies with such non-comparable drug product which may also be imposed by any regulatory agency upon review of the comparability data. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.
The process of manufacturing biologics, such as vilobelimab, is extremely susceptible to product loss
The process of manufacturing our products is complex, highly regulated and subject to several other risks. The process of manufacturing biologics, such as vilobelimab, is extremely susceptible to product loss due to contamination, equipment failure or improper installation or operation of equipment, vendor or operator error, inconsistency in yields, variability in product characteristics and difficulties in scaling the production process. Even minor deviations from normal manufacturing processes could result in reduced production yields, product defects and other supply disruptions. If microbial, viral or other contaminations are discovered in our product candidates or in the manufacturing facilities in which our product candidates are made, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination. Further, our product candidates that have been produced and are stored for later use may degrade, become contaminated or suffer other quality defects, which may cause the affected product candidates to no longer be suitable for their intended use in clinical trials or other development activities. If the defective product candidates cannot be replaced in a timely fashion, we may incur significant delays in our development programs that could adversely affect the value of such product candidates and, thus, adversely affect our business, financial condition, results of operations and prospects.
Our manufacturing process is subject to quality control risks and related regulatory requirements
We participate in the manufacturing process with crucial quality control testing within our own laboratories, and we hold the manufacturer license for, and therefore oversee, the overall manufacturing process, and we are responsible for ensuring that this part of our business also operates according to cGMP standards. Additionally, we hold an importing license. We therefore employ key personnel within the manufacturing process, such as a head of quality assurance, a head of manufacturing and a qualified person.
Thus, our laboratories and our quality control system and related documentation and personnel, are also subject to frequent governmental inspections to assure adherence to cGMP guidelines and to maintain our manufacturing and importing license. Related to these activities, there are risks which could negatively impact our ability to meet our expected clinical development timelines and harm our business, financial condition and prospects, including:
● | a loss of key personnel within the manufacturing activities could result in significant delays in the manufacturing and release testing of our drug candidate and replacement of such personnel could be time consuming and be associated with additional costs for us; |
● | mistakes or misconduct within the release testing could result in false results which could result in both, the wrongfully rejection of a manufactured drug product from being released or the wrongfully acceptance of a dysfunctional drug product, causing data and trial results achieved with such drug product being false and potentially wrongly interpreted; and |
● | an inadequate cGMP compliance could result in a potential temporary or permanent loss of the manufacturing or importing license resulting from an inspection of regulatory agencies. |
-27-
Our third-party manufacturers, or we, may not be able to comply with the cGMP regulatory requirements applicable to vilobelimab and biologics, including applicable provisions of the FDA’s drug cGMP regulations, device cGMP requirements embodied in the Quality System Regulation, or QSR, or similar regulatory requirements outside the United States. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, seizures or voluntary recalls of product candidates, operating restrictions and criminal prosecutions, any of which could significantly affect supplies of our product candidates. In addition, our third-party manufacturers and suppliers and we are subject to FDA and other local regulatory authority inspection from time to time. Failure by our third-party manufacturers and suppliers or us to pass such inspections and otherwise satisfactorily complete the FDA approval regimen with respect to our product candidate may result in regulatory actions such as the issuance of FDA Form 483 notices of observations, warning letters or injunctions or the loss of operating licenses.
In addition, we and our third-party manufacturers and suppliers are subject to numerous environmental, health and safety laws and regulations, including those governing the handling, use, storage, treatment and disposal of waste products, and failure to comply with such laws and regulations could result in significant costs associated with civil or criminal fines and penalties for such third parties. Based on the severity of the regulatory action, our clinical or commercial supply of drug and packaging and other services could be interrupted or limited, which could have a material adverse effect on our business, including our clinical research activities and our ability to develop our product candidates and market our products following approval, if any.
If any third-party manufacturer of our product candidates is unable to increase the scale of its production of our product candidates, and/or increase the product yield of its manufacturing, then our costs to manufacture the product may increase and commercialization may be delayed
In order to produce sufficient quantities to meet the demand for clinical trials and, if approved, subsequent commercialization of vilobelimab or any of our other product candidates in our pipeline or that we may develop, our third-party manufacturers will be required to increase their production and optimize their manufacturing processes while maintaining the quality of the product. The transition to larger scale production could prove difficult or costly. Further, any claims in our manufacturing process as a result of scaling up or optimization of the manufacturing, supply and fill process may result in the need to obtain regulatory approvals. If our third-party manufacturers are not able to optimize manufacturing process to increase the product yield for our product candidates or are unable to produce increased amounts of our product candidates while maintaining the quality of the product, then we may not be able to meet the demands of clinical trials or market demands, which could decrease our ability to generate profits. Difficulty in achieving commercial scale-up production or production optimization or the need for additional regulatory approvals as a result could have a material adverse impact on our business and results of operations.
We expect to seek to establish collaborations and, if we are not able to establish them on commercially reasonable terms, we may have to alter our development and commercialization plans
We expect to seek one or more collaborators for the development and commercialization of one or more of our product candidates. Likely collaborators may include large and mid-size pharmaceutical companies, regional and national pharmaceutical companies and biotechnology companies. In addition, if we obtain marketing authorization or approval for product candidates from foreign regulatory authorities, we may enter into strategic relationships with international biotechnology or pharmaceutical companies for the commercialization of such product candidates outside of the United States.
We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the potential differentiation of our product candidate from competing product candidates, design or results of clinical trials, the likelihood of approval by the FDA, the EMA or comparable foreign regulatory authorities and the regulatory pathway for any such approval, the potential market for the product candidate, the costs and complexities of manufacturing and delivering the product to patients and the potential of competing products. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available for collaboration and whether such a collaboration could be more attractive than the one with us for our product candidate. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate product revenue.
-28-
Collaborations are complex and time-consuming to negotiate and document. Further, there have been a significant number of recent business combinations among large pharmaceutical companies that may have resulted in a reduced number of potential future collaborators. Any collaboration agreements that we enter into in the future may contain restrictions on our ability to enter into potential collaborations or to otherwise develop specified product candidates. We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all.
If we are unable to do so, we may have to curtail the development of the product candidate for which we are seeking to collaborate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense.
If we enter into collaborations with third parties for the development and commercialization of our product candidates, our prospects with respect to those product candidates will depend in significant part on the success of those collaborations
We expect to maintain existing collaborations and enter into additional collaborations for the development and commercialization of certain of our product candidates and in certain geographies. We may have limited control over the amount and timing of resources that our collaborators will dedicate to the development or commercialization of our product candidates. Our ability to generate revenues from these arrangements will depend on any future collaborators’ abilities to successfully perform the functions assigned to them in these arrangements. In addition, any future collaborators may have the right to abandon research or development projects and terminate applicable agreements, including funding obligations, prior to or upon the expiration of the agreed upon terms.
Collaborations involving our product candidates pose a number of risks, including the following:
● | collaborators have significant discretion in determining the efforts and resources that they will apply to these collaborations; |
● | collaborators may not perform their obligations as expected; |
● | collaborators may not pursue development and commercialization of our product candidates or may elect not to continue or renew development or commercialization programs, based on clinical trial results, changes in the collaborators’ strategic focus or available funding or external factors, such as an acquisition, that divert resources or create competing priorities; |
● | collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing; |
● | collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our product candidates; |
● | a collaborator with marketing and distribution rights to one or more products may not commit sufficient resources to the marketing and distribution of such product or products; |
● | disagreements with collaborators, including disagreements over proprietary rights, including trade secrets and other intellectual property, contract interpretation, or the preferred course of research and development might cause delays or termination of the research, development or commercialization of product candidates, might lead to additional responsibilities for us with respect to product candidates, or might result in litigation or arbitration, any of which would be time-consuming and expensive; |
● | collaborators may not properly prosecute, maintain, defend or enforce our intellectual property rights or may use our proprietary information or other intellectual property in such a way as to invite litigation that could jeopardize or invalidate our intellectual property or expose us to potential litigation; |
● | collaborators may infringe, misappropriate or otherwise violate the intellectual property rights of third parties, which may expose us to litigation and potential liability; |
● | collaborations may be terminated and, if terminated, may result in a need for additional capital to pursue further development or commercialization of the applicable product candidates; and |
● | collaboration agreements may not lead to development or commercialization of product candidates in the most efficient manner or at all. If any future collaborator of ours is involved in a business combination, it could decide to delay, diminish or terminate the development or commercialization of any product candidate licensed to it by us. |
-29-
Changes in funding or disruptions at the FDA and other governmental agencies caused by funding shortages or global health concerns could hinder their ability to perform normal business functions on which the operation of our business may rely, which could negatively impact our business
The ability of the FDA to review and clear or approve new product candidates and products can be affected by a variety of factors, including:
● | government budget and funding levels, and statutory, regulatory and policy changes; |
● | the FDA’s ability to hire and retain key personnel and accept the payment of user fees; and |
● | federal government shutdowns and other events that may otherwise affect the FDA’s ability to perform routine functions. |
Average review times at the agency have fluctuated in recent years as a result.
Further, if a prolonged government shutdown occurs, or if global health concerns continue to prevent or delay the FDA or other regulatory authorities from conducting, at all or in a timely manner, their regular inspections, reviews or other regulatory activities, the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions could be significantly impacted, which could have a material adverse effect on our business.
3. Risks related to our intellectual property
Our success depends on our ability to obtain, maintain, protect, defend and enforce patent, trade secret and other intellectual property protection
Our success depends on our ability to obtain, maintain, protect, defend and enforce patent, trade secret and other intellectual property protection in the United States and other countries with respect to vilobelimab and other proprietary product candidates. If we do not adequately protect, maintain, defend and enforce our intellectual property rights, competitors may be able to erode, negate or preempt any competitive advantage we may have, which could adversely affect our business and ability to achieve profitability. To seek to protect our proprietary position, we file patent applications in the United States and in certain other countries related to our novel product candidates and their potential use in different medical indications that are important to our business. The patent application and approval process is expensive and time-consuming and we may not be able to file and prosecute all necessary or desirable patent applications and obtain and maintain issued patents at a reasonable cost or in a timely manner.
If the scope of the patent protection we obtain is not sufficiently broad, we may not be able to prevent others from developing and commercializing technology and products similar or identical to ours. The degree of patent protection we require to successfully compete in the market may be unavailable or severely limited in some cases and may not adequately protect our rights or permit us to gain or keep any competitive advantage. Although we enter into non-disclosure and confidentiality agreements with parties who have access to confidential or patentable aspects of our research and development output, such as our employees, contractors, prospective business collaborators, clinical investigators and other third parties, any of these parties could breach the agreements and disclose such output before a patent application is filed, which could jeopardize our ability to seek and obtain patent protection. In addition, publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot be certain that we were the first to make the inventions claimed in our patents or pending patent applications, or that we were the first to file for patent protection of such inventions.
-30-
The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has been the subject of much litigation in recent years. As a result, the issuance, scope, validity, enforceability, and commercial value of our patent rights may be uncertain. Our pending and future patent applications may not result in patents being issued which protect our technology or product candidates or which effectively prevent others from commercializing competitive technologies and product candidates. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Even if our patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors or other third parties from competing with us, or otherwise provide us with any competitive advantage. For example, there can be no assurance that our issued patents contain and pending patent applications will contain, when granted, claims of sufficient breadth to cover all antibodies alleged to be a biosimilar of our product candidates. Furthermore, there can be no assurance that our issued patents will not be challenged at the United States Patent and Trademark Office, or USPTO, or foreign patent offices or in court proceedings, and if any such challenge were successful, the scope of our issued patent claims could be limited so as to not cover antibodies alleged to be a biosimilar of our product candidates. In addition, changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection. In addition, the laws of other countries may not protect our rights to the same extent or in the same manner as the laws of the United States. For example, patent laws in various jurisdictions, including significant commercial markets, such as Europe, restrict the patentability of methods of treatment of the human body more than patent laws in the United States.
Some of our future patents and patent applications and other intellectual property may be co-owned with third parties. If we are unable to obtain an exclusive license to any such third-party co-owners’ interest in such patents or patent applications or other intellectual property, such co-owners may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and technology. In addition, we would need the cooperation of any such co-owners of our patents in order to enforce such patents against third parties, and such cooperation may not be provided to us. Furthermore, we, or any future partners, collaborators, or licensees, may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent position. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.
Our patents covering our proprietary anti-C5a and anti C5aR technologies may be subject to challenge, narrowing, circumvention and invalidation by third parties
Any of our patents may be challenged, narrowed, circumvented, or invalidated by third parties. The issuance of a patent is not conclusive as to its inventorship, scope, validity, or enforceability, and our patents may be challenged in the courts or patent offices in the United States and elsewhere. We may be subject to a third-party pre-issuance submission of prior art to the USPTO or become involved in opposition, derivation, revocation, reexamination, post-grant and inter partes review, or interference proceedings challenging our patent rights or the patent rights of others. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, enforceability or invalidate, our patent rights, allow third parties to commercialize our technology or products and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights. Moreover, we may have to participate in interference proceedings declared by the USPTO to determine priority of invention or in post-grant challenge proceedings, such as oppositions in a foreign patent office, that challenge priority of invention or other features of patentability. Such challenges may result in loss of patent rights, loss of exclusivity, or in patent claims being narrowed, invalidated, or held unenforceable, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of our technology and product candidates. Such proceedings also may result in substantial cost and require significant time from our scientists and management, even if the eventual outcome is favorable to us.
In addition, our competitors and other third parties may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner. For example, a third party may develop a competitive therapy that provides benefits similar to vilobelimab or other product candidates but that uses a technology that falls outside the scope of our patent protection. Our competitors may also seek approval to market generic versions of any approved products and in connection with seeking such approval may claim that our patents are invalid, unenforceable or not infringed. In these circumstances, we may need to defend or assert our patents, or both, including by filing lawsuits alleging patent infringement. In any of these types of proceedings, a court or other agency with jurisdiction may find our patents invalid or unenforceable, or that our competitors are competing in a non-infringing manner. Thus, even if we have valid and enforceable patents, these patents still may not provide protection against competing products or processes sufficient to achieve our business objectives. If the patent protection provided by the patents and patent applications we hold or pursue with respect to our product candidates is not sufficiently broad to impede such competition, our ability to successfully commercialize our product candidates could be negatively affected, which could have a material adverse effect on our business, financial condition, results of operations and prospects.
-31-
We cannot be sure that we were the first to make the anti-C5a and anti-C5aR technologies claimed in our patents or patent applications or that we were the first to file for patent protection
Assuming the other requirements for patentability are met, currently, the first to file a patent application is generally entitled to the patent. However, prior to March 16, 2013, in the United States, the first to invent was entitled to the patent. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are not published until 18 months after filing, or in some cases not at all. Therefore, we cannot be certain that we were the first to make the inventions claimed in our patents or pending patent applications, or that we were the first to file for patent protection of such inventions. Similarly, we cannot be certain that parties from whom we may license or purchase patent rights were the first to make relevant claimed inventions, or were the first to file for patent protection for them. If third parties have filed patent applications on inventions claimed in our patents or applications on or before March 15, 2013, an interference proceeding in the United States can be initiated by such third parties to determine who was the first to invent the subject matter covered our patent applications. If third parties have filed such applications after March 15, 2013, a derivation proceeding in the United States can be initiated by such third parties to determine whether our invention was derived from theirs.
The patent application process is subject to numerous risks and there can be no assurance that we will be successful in obtaining patents for which we have applied
Pending patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless and until such patent is issued. The patent application process is subject to numerous risks and uncertainties, and there can be no assurance that we or any of our future development partners will be successful in protecting our product candidates by obtaining and defending patents. These risks and uncertainties include the following:
● | the USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other provisions during the patent process. There are situations in which noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have been the case; |
● | the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance; |
● | patent applications may not result in any patents being issued; |
● | patents that may be issued or in-licensed may be challenged, invalidated, modified, revoked, circumvented, narrowed, found to be unenforceable or otherwise may not provide any competitive advantage; |
● | our competitors, many of whom have substantially greater resources and many of whom have made significant investments in competing technologies, may seek or may have already obtained patents that will limit, interfere with or eliminate our ability to make, use, and sell our potential product candidates; |
● | there may be significant pressure on the U.S. government and international governmental bodies to limit the scope of patent protection both inside and outside the United States for disease treatments that prove successful, as a matter of public policy regarding worldwide health concerns; and |
● | countries other than the United States may have patent laws less favorable to patentees than those upheld by U.S. courts, allowing foreign competitors a better opportunity to create, develop and market competing product candidates. |
Any of the foregoing events could have a material adverse effect on our business, financial condition, results of operations and prospects.

It is difficult and costly to protect our intellectual property and our proprietary anti-C5a and anti-C5aR technologies, and we may not be able to ensure their protection
Our commercial success will depend in part on obtaining and maintaining patent protection and trade secret protection for the composition, use and structure of our product candidates, the methods used to manufacture them, the related therapeutic targets and associated methods of treatment as well as on successfully defending these patents against potential third-party challenges. Our ability to protect our product candidates from unauthorized making, using, selling, offering to sell or importing by third parties is dependent on the extent to which we have rights under valid and enforceable patents that cover these activities.
The ultimate determination by the USPTO or by a court or other trier of fact in the United States, or any corresponding foreign patent offices or courts or other triers of fact, on whether a claim meets all requirements of patentability cannot be assured. Although our C5a and C5aR inhibitor portfolio consists of six families of patents and patent applications that we own directed to C5a and C5aR inhibitors and related methods of use, we cannot predict the breadth of claims that may be allowed or enforced in our patents or patent applications, in our future licensed patents or patent applications or in third-party patents.
We cannot provide assurances that any of our patent applications will be found to be patentable, including over our own prior art patents, publications or other disclosures. Furthermore, given the differences in patent laws in the United States, Europe and other foreign countries, for example, the availability of grace periods for filing patent applications and what can be considered as prior art, we cannot make any assurances as to the scope of any claims that may issue from our pending and future patent applications in the United States or in other jurisdictions. Similarly, we cannot make any assurances as to the scope of any claims that may survive a proceeding initiated by a third party challenging the patentability, validity or enforceability of our patents and patent applications in the United States or in other jurisdictions. Any such challenge, if successful, could limit patent protection for our product candidates and/or materially harm our business.
The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:
● | we may not be able to generate sufficient data to support patent applications that protect the entire breadth of developments in one or more of our programs; |
● | it is possible that one or more of our pending patent applications will not become an issued patent or, if issued, that the patent(s) will be insufficient to protect our technology or products, provide us with a basis for commercially viable products or provide us with any competitive advantages; |
● | if our pending patent applications issue as patents, they may be challenged by third parties as not infringed, invalid or unenforceable under United States or foreign laws; or |
● | if issued, the patents under which we hold rights may not be valid or enforceable. |
In addition, to the extent that we are unable to obtain and maintain patent protection for one of our product candidates or in the event that such patent protection expires, it may no longer be cost-effective to extend our portfolio by pursuing additional development of a product or product candidate for follow-on indications. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.
Obtaining and maintaining patent protection of our anti-C5a and anti-C5aR technologies depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements
Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and applications are required to be paid to the USPTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the patents and applications. The USPTO and various non-U.S. governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process and after a patent has issued. There are situations in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. We may enter into certain license agreements where we will not have the ability to maintain or prosecute patents in the portfolio and must therefore rely on third parties to take such actions and comply with certain requirements. Failure by us or our future or any existing licensors to maintain protection of our patent portfolio could have a material adverse effect on our business, financial condition, results of operations and prospects.
-33-
In addition, it is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example with respect to proper priority claims, inventorship, claim scope, or requests for patent term adjustments. If we fail to establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced, eliminated, invalid and/or unenforceable. If any of our present or future partners, collaborators, licensees, or licensors, are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution, or enforcement of our patents or patent applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair our ability to prevent competition from third parties, which may have a material adverse effect on our business, financial condition, results of operations and prospects.
Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time and if we do not obtain protection under the Drug Price Competition and Patent Term Restoration Act of 1984, or Hatch-Waxman Amendments, and similar non-U.S. legislation for extending the term of patents covering each of our product candidates, our business may be materially harmed.
Patents have a limited lifespan. In the United States, the natural expiration of a patent is generally twenty years after it is filed. Various extensions may be available, however, the life of a patent, and the protection it affords, is limited. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with adequate and continuing patent protection sufficient to exclude others from commercializing products similar to our product candidates.
Depending upon the timing, duration and conditions of the FDA marketing approval of our product candidates, one or more of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments and similar legislation in the EU and other jurisdictions. The Hatch-Waxman Amendments permit a patent term extension of up to five years for a patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent may be extended and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended. In Europe, a maximum of five and a half years of supplementary protection can be achieved for an active ingredient or combinations of active ingredients of a medicinal product protected by a basic patent, if a valid marketing authorization exists (which must be the first authorization to place the product on the market as a medicinal product) and if the product has not already been the subject of supplementary protection. However, we may not receive an extension if we fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements. Moreover, the length of the extension could be less than we request. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can enforce our patent rights for that product will be shortened and our competitors may obtain approval to market competing products sooner. As a result, our revenue from applicable products could be reduced and could have a material adverse effect on our business, financial condition, results of operations and prospects.
Others may claim an ownership interest in our intellectual property and proprietary anti-C5a and anti-C5aR technologies which could expose us to litigation and have a significant adverse effect on our prospects
A third party may claim an ownership interest in one or more of our, or our future or any existing licensors’, patents or other proprietary or other intellectual property rights. A third party could bring legal actions against us and seek monetary damages and/or enjoin clinical testing, manufacturing and marketing of the affected product or products. While we are presently unaware of any material claims or assertions by third parties with respect to our patents or other intellectual property, we cannot guarantee that a third party will not assert a claim or an interest in any of such patents or other intellectual property. If we become involved in any litigation, it could consume a substantial portion of our resources, and could cause a significant diversion of effort by our technical and management personnel. If any of these actions are successful, in addition to any potential liability for damages, we could be required to obtain a license to continue to manufacture or market the affected product, in which case we may be required, for example, to pay substantial royalties or grant cross-licenses to our patents. We cannot, however, assure you that any such license will be available on acceptable terms, if at all. Ultimately, we could be prevented from commercializing a product, or be forced to cease some aspect of our business operations as a result of claims of patent infringement or other violations of other intellectual property rights. Further, the outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in advance, including the demeanor and credibility of witnesses and the identity of any adverse party. This is especially true in intellectual property cases that may turn on the testimony of experts as to technical facts upon which experts may reasonably disagree. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.
-34-
If we are sued for infringing, misappropriating, or otherwise violating intellectual property rights of third parties, such litigation could be costly and time consuming and could prevent or delay us from developing or commercializing our product candidates
Our commercial success depends, in part, on our ability to develop, manufacture, market and sell our product candidates without infringing, misappropriating, or otherwise violating the proprietary or any other intellectual property rights of third parties. Third parties may have U.S. and non-U.S. issued patents and pending patent applications relating to compounds, methods of manufacturing compounds and/or methods of use for the treatment of the disease indications for which we are developing our product candidates that may cover our product candidates or approach to complement inhibition. If any third-party patents or patent applications are found to cover our product candidates or their methods of use or manufacture, or our approach to complement inhibition, we may not be free to manufacture or market our product candidates as planned without obtaining a license, which may not be available on commercially reasonable terms or at all.
There is a substantial amount of intellectual property litigation in the biotechnology and pharmaceutical industries, and we may become party to, or threatened with, litigation or other adversarial proceedings regarding intellectual property rights with respect to our product candidates, including interference and post-grant proceedings before the USPTO. There may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment related to the composition, use or manufacture of our product candidates. Because patent applications can take many years to issue, there may be pending patent applications which may later result in issued patents that our product candidates may be accused of infringing. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. Accordingly, third parties may assert infringement claims against us based on intellectual property rights that exist now or arise in the future. The outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in advance. The pharmaceutical and biotechnology industries have produced a significant number of patents, and it may not always be clear to industry participants, including us, which patents cover various types of products or methods of use or manufacture. The scope of protection afforded by a patent is subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we would need to demonstrate that our product candidates, products or methods either do not infringe the patent claims of the relevant patent or that the patent claims are invalid or unenforceable, and we may not be able to do this. Proving invalidity is difficult. For example, in the United States, proving invalidity requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents. Even if we are successful in these proceedings, we may incur substantial costs and the time and attention of our management and scientific personnel could be diverted in pursuing these proceedings, which could significantly harm our business and operating results. In addition, we may not have sufficient resources to bring these actions to a successful conclusion.
If we are found to infringe, misappropriate, or otherwise violate a third party’s intellectual property right, we could be forced, including by court order, to cease developing, manufacturing or commercializing the infringing product candidate or product. Alternatively, we may be required to obtain a license from such third party in order to use the infringing technology and continue developing, manufacturing or commercializing the infringing product candidate or product. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us; alternatively or additionally, it could include terms that impede or destroy our ability to compete successfully in the commercial marketplace. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing our product candidates or force us to cease some of our business operations, which could harm our business. Claims that we have misappropriated the trade secrets or other confidential information of any third parties could have a similar negative impact on our business. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.
-35-
We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property and proprietary anti-C5a and anti-C5aR technologies
Many of our current and former employees and our licensors’ current and former employees, including our senior management, were previously employed at universities or at other biotechnology or pharmaceutical companies, including some which may be competitors or potential competitors. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these employees have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such third party. Litigation may be necessary to defend against such claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel or sustain damages. Such intellectual property rights could be awarded to a third party, and we could be required to obtain a license from such third party to commercialize our technology or products. Such a license may not be available on commercially reasonable terms or at all. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.
In addition, while we typically require our employees, consultants and contractors who are involved in the development of intellectual property for us within the scope of such employees’, consultants’ and contractors’ employment or other engagement by us to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our own, or such agreements may be breached or alleged to be ineffective, which may result in claims by or against us related to the ownership of such intellectual property. If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to our senior management and scientific personnel. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.
We may lose exclusivity to certain of our intellectual property rights to the German federal government
We hold all of our intellectual property through our wholly owned subsidiary InflaRx GmbH in Germany. In the event of a national epidemic or pandemic, the German federal government, and the Federal Ministry of Health and other authorities have the right to order the use of our owned and in-licensed patents in the interest of the public welfare or the security of the Federal Republic of Germany. The German federal government may issue such an order with respect to our owned and in-licensed patents and we may lose exclusivity with respect to the technologies covered by such patents.
Additionally, the research resulting in certain of our patents and technology, including patents and technology relating to our clinical development in severe COVID-19, was funded in part by the German federal government. Results of such government funded research projects must, subject to certain conditions, be made available free of charge for academic research and teaching in Germany and must be published in bi-annual interim reports and a final report following completion of the funded work. Information relating to intellectual property generated, commercial expectations, scientific chances of success, next steps and certain additional information must be disclosed to the German government and to third parties for academic research and teaching upon request under a written confidentiality agreement. The German federal government additionally has, in the case of a special public interest, a non-exclusive and transferable right to use intellectual property generated as part of the funded work.
-36-
Certain of our employees and directors are subject to German law, including as it relates to the ownership of, and compensation for, inventions
A number of our personnel, including some of our directors, work in Germany and may be subject to German employment law. Inventions that may be the subject of a patent or of protection as a utility model as well as technical improvement proposals for other technical innovations that may not be the subject of a patent or of protection as a utility model made by such employees are subject to the provisions of the German Act on Employees’ Inventions (Gesetz über Arbeitnehmererfindungen), which regulates the ownership of, and compensation for, inventions made by employees. We face the risk that disputes may occur between us and our current or past employees pertaining to the sufficiency of compensation paid by us, allocation of rights to inventions under the German Act on Employee’s Inventions or alleged non-adherence to the provisions of this act, any of which may be costly to resolve and take up our management’s time and efforts whether we prevail or fail in such dispute. In addition, under the German Act on Employees’ Inventions, certain employees retain rights to patents they invented or co-invented and disclosed to us prior to October 1, 2009. While we believe that all of our current and past German employee inventors have subsequently assigned to us their interest in patents and inventions they invented or co-invented, there can be no assurance that all such assignments are fully effective. Even if we lawfully own all inventions of our employee inventors who are subject to the German Act on Employees’ Inventions, we are required under German law to reasonably compensate such employees for the use of the patents.
If any of our current or past employees obtain or retain ownership of any inventions or other intellectual property rights that we believe we own, we may lose valuable intellectual property rights and may be required to obtain and maintain licenses from such employees to such inventions or intellectual property rights, which may not be available on commercially reasonable terms or at all, or may be non-exclusive. If we are unable to obtain and maintain a license to any such employee’s interest in such inventions or intellectual property rights, we may need to cease the development, manufacture, and commercialization of one or more of the product candidates we may develop. In addition, any loss of exclusivity of our intellectual property rights could limit our ability to stop others from using or commercializing similar or identical technology and products. Any of the foregoing events could have a material adverse effect on our business, financial condition, results of operations and prospects.
We may not be able to enforce our intellectual property rights throughout the world
Filing, prosecuting, maintaining, enforcing and defending patents on our product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. The requirements for patentability may differ in certain countries, particularly in developing countries; thus, even in countries where we do pursue patent protection, there can be no assurance that any patents will issue with claims that cover our product candidates.
Moreover, our ability to protect and enforce our intellectual property rights may be adversely affected by unforeseen changes in the United States and foreign intellectual property laws. Additionally, laws of some countries outside of the United States and Europe do not afford intellectual property protection to the same extent as the laws of the United States and Europe. Many companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems of some countries, including India, China and other countries, do not favor the enforcement of patents and other intellectual property rights. This could make it difficult for us to stop the infringement of our patents or the misappropriation or other violations of our other intellectual property rights. For example, many countries outside the United States have compulsory licensing laws under which a patent owner must grant licenses to third parties. Consequently, we may not be able to prevent third parties from practicing our inventions in certain countries outside the United States and Europe. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop and market their own products and, further, may export otherwise infringing products to jurisdictions where we have patent protection, if our ability to enforce our patents to stop infringing activities is inadequate. These products may compete with our products, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.
Agreements under which we may be granted a license to any patent rights may not give us sufficient rights to permit us to pursue enforcement of our licensed patents or defense of any claims asserting the invalidity of these patents (or control of enforcement or defense) of such patent rights in all relevant jurisdictions as requirements may vary.
Proceedings to enforce our patent rights in the United States or foreign jurisdictions, whether or not successful, could result in substantial costs and divert our efforts and resources from other aspects of our business. Moreover, such proceedings could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Furthermore, while we intend to seek to protect our intellectual property rights in major markets for our product candidates, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market our product candidates. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.
-37-
We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and unsuccessful
Our competitors and others may infringe, misappropriate or otherwise violate our patents or other intellectual property rights. To counter infringement or unauthorized use, we may be required to file infringement or other claims, which can be expensive and time consuming and divert the time and attention of our management and scientific personnel.
Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their patents, in addition to counterclaims asserting that our patents are invalid or unenforceable, or both. In any patent infringement proceeding, there is a risk that a court will decide that a patent of ours is invalid or unenforceable, in whole or in part, and that we do not have the right to stop the other party from using the invention at issue. There is also a risk that, even if the validity of such patents is upheld, the court will construe the patent’s claims narrowly or decide that we do not have the right to stop the other party from using the invention at issue on the grounds that our patent claims do not cover the invention. An adverse outcome in a litigation or proceeding involving one or more of our patents could limit our ability to assert those patents against those parties or other competitors and may curtail or preclude our ability to exclude third parties from developing, making and selling similar or competitive products. Even if we establish infringement, the court may decide not to grant an injunction against further infringing activity and instead award only monetary damages, which may or may not be an adequate remedy. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could adversely affect the price of our ordinary shares. Moreover, there can be no assurance that we will have sufficient financial or other resources to file and pursue such infringement claims, which typically last for years before they are concluded. Even if we ultimately prevail in such claims, the monetary cost of such litigation and the diversion of the attention of our management and scientific personnel could outweigh any benefit we receive as a result of the proceedings. Any such litigation could have a material adverse effect on our business, financial condition, results of operations and prospects.
If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our marks of interest and our business may be adversely affected
Our trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names or may be forced to stop using these names, which we need for name recognition by potential partners or customers in our markets of interest. During trademark registration proceedings, we may receive rejections that we are unable to overcome, in the USPTO and in comparable agencies in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive such proceedings. If we are unable to establish name recognition based on our trademarks and trade names, we may not be able to compete effectively and our business may be adversely affected.
If we fail to comply with our obligations under any future or other intellectual property licenses with third parties, we could lose license rights that are important to our business
We may be reliant upon licenses to certain patent rights and proprietary anti-C5a and anti-C5aR technologies and other intellectual property from third parties that are important or necessary to the development of our product candidates and the manufacture and other commercialization of our products. These and other licenses may not provide exclusive rights to use such intellectual property and technology in all relevant fields of use and in all territories in which we may wish to develop, manufacture or commercialize our technology and products in the future. As a result, we may not be able to prevent competitors from developing, manufacturing and commercializing competitive products in territories included in all of our licenses. Our licensors may have sublicensed patents and other intellectual property owned by a third party, or relied on third-party consultants or collaborators or funds from third parties that have an ownership or other right, title or interest in or to such in-licensed intellectual property, such that our licensors are not the sole and exclusive owners of the patents and other intellectual property we in-license. This could have a material adverse effect on our competitive position, business, financial conditions, results of operations and prospects.
-38-
In addition, agreements under which we may license patent rights may not give us control over patent filings prosecution or maintenance, so that we may not be able to control which claims or arguments are presented and may not be able to secure, maintain, or successfully enforce and defend necessary or desirable patent protection from those patent rights. We cannot be certain that patent filing prosecution and maintenance activities by our licensors will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents. Even if we are permitted to pursue such enforcement or defense, we will require the cooperation of our future or any existing licensors, and cannot guarantee that we would receive it and on what terms. We cannot be certain that our future licensors will allocate sufficient resources or prioritize their or our enforcement of such patents or defense of such claims to protect our interests in any licensed patents. If we cannot obtain patent protection or enforce existing or future patents against third parties, it could have a material adverse effect on our business, financial condition, results of operations and prospects.
Further, agreements under which we may license technology or any other intellectual property to or from third parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant technology or any other intellectual property, or increase what we believe to be our financial or other obligations under the relevant agreement. Moreover, if disputes over technology or other intellectual property that we may license prevent or impair our ability to maintain our licensing arrangements on commercially acceptable terms, we may be unable to successfully develop manufacture and commercialize the affected product candidates, which could have a material adverse effect on our business, financial conditions, results of operations and prospects.
Disputes may arise regarding intellectual property subject to a licensing agreement, including:
● | the scope of rights that may be granted under license agreements and other interpretation-related issues; |
● | the extent to which our technology and processes infringe on intellectual property rights of the licensor that is not subject to the licensing agreement; |
● | the sublicensing of patent and other rights under current and any future collaborative development relationships; |
● | our diligence obligations under any license agreement and what activities satisfy such obligations; |
● | the inventorship and ownership of inventions and know-how and other intellectual property resulting from the joint creation or use of intellectual property by our license counterparties and us and our partners; and |
● | the priority of invention of patented technology. |
In spite of our best efforts, our license counterparties might conclude that we have materially breached our license agreements and might therefore terminate the license agreements, which may remove our ability to develop manufacture- and commercialize the product candidates and technology covered by these license agreements. If any in-licenses are terminated, competitors may be able to seek regulatory approval of, and to market, products identical to ours. It is possible that we may be unable to obtain any additional licenses that we require at a reasonable cost or on reasonable terms, if at all. In that event, we may be required to expend significant time and resources to redesign our product candidates, technology, or the methods for manufacturing them or to develop or license replacement technology, all of which may not be feasible on a technical or commercial basis. If we are unable to do so, we may be unable to develop, manufacture or commercialize the affected product candidates, which could harm our competitive position, business, financial conditions, results of operations and prospects.
-39-
If we are unable to protect the confidentiality of our trade secrets, the value of our technology could be negatively impacted and our business would be harmed
In addition to the protection afforded by patents, we also rely on trade secret protection for certain aspects of our intellectual property. However, trade secrets are difficult to protect. We seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, consultants, independent contractors, advisors, contract manufacturers, suppliers and other third parties. We also enter into confidentiality and invention or patent assignment agreements with employees and certain consultants and independent contractors. Any party with whom we have executed such an agreement may breach that agreement and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. Additionally, if the steps taken to maintain our trade secrets are deemed inadequate, we may have insufficient recourse against third parties for misappropriating the trade secret. Further, if any of our trade secrets were to be lawfully obtained or independently developed by a competitor or other third party, we would have no right to prevent such third party, or those to whom they communicate such technology or information, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed or otherwise obtained by a competitor or other third party, it could have a material adverse effect on our business, financial condition, results of operations and prospects.
4. | Risks related to employee matters and managing growth |
We only have a limited number of employees to manage and operate our business
As of December 31, 2023, we had 66 full-time or part-time employees. Our focus on the development and commercialization of vilobelimab requires us to optimize cash utilization and to manage and operate our business with limited personnel. We cannot assure you that we will be able to hire additional employees and/or retain adequate staffing levels to develop and commercialize vilobelimab or run our operations or to accomplish all the objectives that we otherwise would seek to accomplish.
We depend heavily on our executive officers and directors, and the loss of their services would materially harm our business
Our success depends, and will likely continue to depend, upon our ability to hire and retain the services of our current executive officers, directors, principal consultants and others. We are highly dependent on the management, development, clinical, financial and business development expertise of Niels Riedemann, our Chief Executive Officer, Renfeng Guo, our Chief Scientific Officer, Thomas Taapken, our Chief Financial Officer, and, since July 2023, Camilla Chong, our Chief Medical Officer. Our ability to compete in the biotechnology and pharmaceuticals industries depends upon our ability to attract and retain highly qualified managerial, scientific and medical personnel.
Our industry has experienced a high rate of turnover of management personnel in recent years. Any of our personnel may terminate their employment at will. If we lose one or more of our executive officers or other key employees, our ability to implement our business strategy successfully could be seriously harmed. Furthermore, replacing executive officers or other key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to develop, gain marketing approval of and commercialize products successfully.
Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these additional key employees on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions.
We rely on consultants and advisors, including scientific, strategic, regulatory and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may be employed by other entities and may have commitments under consulting or advisory contracts with those entities that may limit their availability to us. If we are unable to continue to attract and retain highly qualified personnel, our ability to develop and commercialize our product candidates will be limited.

We expect to expand our organization, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations
We expect to expand scope of our operations, particularly in the areas of clinical development and regulatory affairs. To manage such growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Our management may need to devote a significant amount of its attention to managing these growth activities. Moreover, our expected growth could require us to relocate to a different geographic area of the country. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expansion or relocation of our operations, retain key employees, or identify, recruit, attract and train retain human capital. Competition for qualified, motivated, and highly-skilled executives, professionals and other key personnel in biotechnology and pharmaceuticals industries is significant. Our inability to manage the expansion or relocation of our operations effectively may result in weaknesses in our infrastructure, give rise to operational mistakes, loss of business opportunities, loss of employees and reduced productivity among remaining employees. Our expected growth could also require significant capital expenditures and may divert financial resources from other projects, such as the development of additional product candidates. If we are unable to effectively manage our expected growth, our expenses may increase more than expected, our ability to generate revenues could be reduced and we may not be able to implement our business strategy, including the successful development and commercialization of our product candidates.
Our employees, independent contractors, consultants, collaborators and CROs may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements, which could cause significant liability for us and harm our reputation
We are exposed to the risk that our employees, independent contractors, consultants, collaborators and CROs may engage in fraudulent conduct or other illegal activity. Misconduct by those parties could include intentional, reckless or negligent conduct or disclosure of unauthorized activities to us that violates: (i) the FDA regulations or similar regulations of comparable non-U.S. regulatory authorities, including those laws requiring the reporting of true, complete and accurate information to such authorities, (ii) manufacturing and clinical trial conduct standards, (iii) federal and state healthcare fraud and abuse laws and regulations and similar laws and regulations established and enforced by comparable non-U.S. regulatory authorities, and (iv) laws that require the reporting of financial information or data accurately. Activities subject to these laws also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws, standards or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business and results of operations, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could have a material adverse effect on our ability to operate our business and our results of operations.
5. | Risks related to our ordinary shares and our status as a public company |
The trading price of our ordinary shares has been and may in the future be highly volatile, which could result in substantial losses for holders of our ordinary shares, and a decline in our share price and invite securities litigation against our company or our management
Our share price has been and is likely to be highly volatile in the future. The stock market in general and the market for smaller pharmaceutical and biotechnology companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. You should consider an investment in our ordinary shares as risky and invest only if you can withstand a significant loss and wide fluctuations in the market value of your investment. The market price for our ordinary shares may be influenced by many factors, including:
● | the timing, enrollment and results of clinical trials of vilobelimab and any other product candidates; |
● | regulatory actions with respect to vilobelimab, our other product candidates or our competitors’ products and product candidates; |
● | the success of the commercialization of GOHIBIC (vilobelimab); |
-41-
● | the success of existing or new competitive products or technologies; |
● | any delay in our development or regulatory filings for vilobelimab or any future product candidate and any adverse development or perceived adverse development with respect to the applicable regulatory authority’s review of such filings, including the FDA’s issuance of a “refusal to file” letter or a request for additional information; |
● | announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures, collaborations or capital commitments; |
● | commencement or termination of collaborations for our development programs; |
● | failure or discontinuation of any of our development programs; |
● | results of clinical trials of product candidates of our competitors; |
● | regulatory or legal developments in the United States and other countries; |
● | developments or disputes concerning patent applications, issued patents or other proprietary rights; |
● | the recruitment or departure of key personnel; |
● | the level of expenses related to any of our product candidates or clinical development programs; |
● | the results of our efforts to develop additional product candidates or products; |
● | actual or anticipated changes in estimates as to financial results or development timelines; |
● | announcement or expectation of additional financing efforts; |
● | sales of our ordinary shares by us, our insiders or other shareholders; |
● | variations in our financial results or those of companies that are perceived to be similar to us; |
● | changes in estimates or recommendations by securities analysts, if any, that cover our shares; |
● | changes in the structure of healthcare payment systems; |
● | market conditions in the pharmaceutical and biotechnology industries; |
● | general economic, industry, market and political conditions; and |
● | the other factors described in this ‘ITEM 3. KEY INFORMATION — 3. Risk factors’ section. |
In the past, securities class action litigation has often been brought against a company and its management following a decline in the market price of its securities. This risk is especially relevant for biopharmaceutical companies, which have experienced significant stock price volatility in recent years. Such litigation, if instituted against us, could cause us or members of our management to incur substantial costs and divert management’s attention and resources from our business.
Future sales, or the possibility of future sales, of a substantial number of our ordinary shares could adversely affect the price of the shares and dilute shareholders
Future sales of a substantial number of our ordinary shares, or the perception that such sales will occur, could cause a decline in the market price of our ordinary shares. If we or our existing shareholders sell substantial amounts of ordinary shares in the public market, or the market perceives that such sales may occur, the market price of our ordinary shares and our ability to raise capital through an issue of equity securities in the future at attractive terms or at all could be adversely affected.
We have broad discretion in the use of our cash on hand and may invest or spend it in a way with which you do not agree and in ways that may not yield a return on your investment
As of December 31, 2023, we had €12.8 million in cash and cash equivalents and €85.6 million in marketable securities. Our management will have broad discretion in the use of such cash and could spend it in ways that do not improve our results of operations or enhance the value of our ordinary shares. You will not have the opportunity to influence our decisions on how to use our cash on hand. The failure by our management to apply these funds effectively could result in financial losses that could harm our business, cause the price of our ordinary shares to decline and delay the development of our product candidates. Pending its use, we may invest our cash on hand in a manner that does not produce income or that loses value.

We are a foreign private issuer and, as a result, we are not subject to U.S. proxy rules and are subject to Exchange Act reporting obligations that, to some extent, are more lenient and less frequent than those of a U.S. domestic public company
We will report under the Securities Exchange Act of 1934, as amended, or the Exchange Act, as a non-U.S. company with foreign private issuer status. Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, including (i) the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act, (ii) the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time and (iii) the rules under the Exchange Act requiring the filing with the SEC of quarterly reports on Form 10-Q containing unaudited financial and other specified information, or current reports on Form 8-K, upon the occurrence of specified significant events. In addition, foreign private issuers are not required to file their Annual Report on Form 20-F until four months after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their Annual Report on Form 10-K within 75 days after the end of each fiscal year. Foreign private issuers are also exempt from the Regulation Fair Disclosure, aimed at preventing issuers from making selective disclosures of material information. As a result of the above, you may not have the same protections afforded to shareholders of companies that are not foreign private issuers.
As a foreign private issuer and as permitted by the listing requirements of Nasdaq, we follow certain home country governance practices rather than the corporate governance requirements of Nasdaq
We are a foreign private issuer. As a result, in accordance with the listing requirements of Nasdaq we rely on home country governance requirements and certain exemptions thereunder rather than relying on the corporate governance requirements of Nasdaq. In accordance with Dutch law and generally accepted business practices, our Articles of Association do not provide quorum requirements generally applicable to general meetings of shareholders. To this extent, our practice varies from the requirement of Nasdaq Listing Rule 5620(c), which requires an issuer to provide in its bylaws for a generally applicable quorum, and that such quorum may not be less than one-third of the outstanding voting stock. Although we must provide shareholders with an agenda and other relevant documents for the general meeting of shareholders, Dutch law does not have a regulatory regime for the solicitation of proxies and the solicitation of proxies is not a generally accepted business practice in the Netherlands; thus, our practice will vary from the requirement of Nasdaq Listing Rule 5620(b). As permitted by the listing requirements of Nasdaq, we have also opted out of the requirements of Nasdaq Listing Rule 5605(d), which requires, among other things, an issuer to have a compensation committee that consists entirely of independent directors and makes determinations regarding the independence of any compensation consultants, Nasdaq Listing Rule 5605(e), which requires independent director oversight of director nominations, and Nasdaq Listing Rule 5605(b)(2), which requires an issuer to have a majority of independent directors on its board. In addition, we have opted out of shareholder approval requirements, as included in the Nasdaq Listing Rules, for the issuance of securities in connection with certain events such as the acquisition of shares or assets of another company, the establishment of or amendments to equity-based compensation plans for employees, a change of control of us and certain private placements. To this extent, our practice varies from the requirements of Nasdaq Rule 5635, which generally requires an issuer to obtain shareholder approval for the issuance of securities in connection with such events. Accordingly, you may not have the same protections afforded to shareholders of companies that are subject to these Nasdaq requirements.
We do not anticipate paying any cash dividends on our share capital in the foreseeable future. Accordingly, shareholders must rely on capital appreciation, if any, for any return on their investment
We have never declared nor paid cash dividends on our share capital. We plan to retain all of our future earnings, if any, to finance the operation, development and growth of our business. In addition, the terms of any future debt or credit agreements and any restrictions imposed by applicable law may preclude us from paying dividends. As a result, capital appreciation, if any, of our ordinary shares will be your sole source of gain for the foreseeable future. Investors seeking cash dividends should not purchase our ordinary shares.
See “ITEM 7. MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS —1. Major shareholders.” elsewhere in this Annual Report for more information regarding the ownership of our outstanding ordinary shares by our executive officers, directors and principal shareholders and their affiliates.
-43-
If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our share price and trading volume could decline
The trading market for our ordinary shares depends in part on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over such analysts. There can be no assurance that analysts will cover us or provide favorable coverage going forward. Securities or industry analysts may elect not to continue to provide research coverage of our ordinary shares, and such lack of research coverage may negatively impact the market price of our ordinary shares. In the event we do have analyst coverage, if one or more analysts downgrade our ordinary shares, change their opinion of our ordinary shares or publish inaccurate or unfavorable research about our business, our share price would likely decline. In addition, if one or more analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.
Our ability to use our net operating loss carry forwards and other tax attributes may be limited
Our ability to utilize our NOLs, or NOLs, is limited, and may be limited further, under Section 8c of the German Corporation Income Tax Act (Körperschaftsteuergesetz), or KStG, and Section 10a of the German Trade Tax Act (Gewerbesteuergesetz), or GewStG. These limitations apply if a qualified ownership change, as defined by Section 8c KStG, occurs and no exemption is applicable. Generally, a qualified ownership change occurs if more than 50% of the share capital or the voting rights are directly or indirectly transferred to a shareholder or a group of shareholders within a period of five years. A qualified ownership change may also occur in case of a transaction comparable to a transfer of shares or voting rights or in case of an increase in capital leading to a respective change in the shareholding. In the case of such a qualified ownership change tax loss carry forwards expire in full. To the extent that the hidden reserves (stille Reserven) taxable in Germany exceed the tax loss carry forward, they may be further utilized despite a qualified ownership change. In case of a qualified ownership change within a group, tax loss carry forwards will be preserved if certain conditions are satisfied. Alternatively, tax loss carry forwards may be retained upon application under certain conditions, to the extent that the corporation has exclusively maintained the same business operations since its establishment or at least since the beginning of the third year prior to qualified ownership change (fortführungsgebundener Verlustvortrag). If the aforementioned application is made and, after the qualified change of ownership, this business operation is discontinued, the most recently determined tax loss carry forward (fortführungsgebundener Verlustvortrag) would be lost.
An appeal has been filed by the fiscal court of Hamburg dated August 29, 2017 – 2 K 245/17 with regard to Section 8c, paragraph 1, sentence 2 KStG (in its superseded version, now: Section 8c paragraph 1 sentence 1 KStG) that is, the forfeiture of all tax loss carryforwards in case more than 50% of shares/voting rights will be assigned to a new shareholder. The appeal is still pending. It is unclear when the Federal Constitutional Court will decide this case. According to statements in German legal literature, there are good reasons to believe that the Federal Constitutional Court may come to the conclusion that Section 8, paragraph 1, sentence 2 KStG (in its superseded version) is not in line with the German constitution.
As of December 31, 2023, we had NOL carry forwards for German corporate tax purposes of €196.0 million and for trade tax purposes €164 million available. Future changes in share ownership may also trigger an ownership change and, consequently, a Section 8c KStG, or a Section 10a GewStG limitation. Any limitation may result in the expiration of the complete tax operating loss carry forwards before they can be utilized. As a result, if we earn net taxable income, our ability to use our pre-change net operating loss carry forwards to reduce German income tax may be subject to limitations, which could potentially result in increased future cash tax liability to us.
As of December 31, 2023, our U.S. subsidiary, InflaRx Pharmaceuticals, Inc., had €12.96 million or $14.3 million of NOLs for U.S. federal income tax purposes. Transfers or issuances of our equity may impair or reduce the ability of InflaRx Pharmaceuticals, Inc. to utilize U.S. federal net operating loss carryforwards and certain other tax attributes in the future. Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, contains rules that limit the ability of a company that undergoes an “ownership change” to utilize its net operating loss and tax credit carry forwards and certain built-in losses recognized in years after the ownership change. An “ownership change” is generally defined as an increase in ownership of a corporation’s stock by more than 50 percentage points over a rolling three-year period by stockholders that own (directly, indirectly or constructively) 5% or more of the stock of a corporation at any time during the relevant rolling three-year period. If an ownership change occurs, Section 382 imposes an annual limitation on the use of pre-ownership change NOLs, credits and certain other tax attributes to offset taxable income earned after the ownership change. The annual limitation is generally equal to the product of the applicable long-term tax-exempt rate in effect for the month in which the ownership change occurs and the value of the company’s stock immediately before the ownership change (subject to some adjustments). For example, this annual limitation may be adjusted to reflect any unused annual limitation for prior years and certain recognized (or treated as recognized) built-in gains and losses for the year. In addition, Section 383 generally limits the amount of tax liability in any post-ownership change year that can be reduced by pre-ownership change tax credit carryforwards or capital loss carryforwards. No assurance can be given that prior transactions have not resulted in an ownership change for purposes of Section 382 of the Code or that future transactions will not result in an ownership change. Even if a subsequent transaction does not result in an ownership change, it may materially increase the likelihood that we will undergo an ownership change in the future. Sales of our common shares by stockholders, whose interests may differ from our interests, may increase the likelihood that we or one of our subsidiaries undergoes an ownership change. If we or our subsidiaries have or were to undergo an ownership change, it could result in increased future tax liability to us.
-44-
We may become taxable in a jurisdiction other than Germany and this may increase the aggregate tax burden on us
Since incorporation we intend to have, on a continuous basis, our place of effective management in Germany. We will therefore be a tax resident of Germany under German national tax law. By reason of our incorporation under Dutch law, we are also deemed tax resident in the Netherlands under Dutch tax law. However, based on our current management structure and current tax laws of the United States, Germany and the Netherlands, as well as applicable income tax treaties, and current interpretations thereof, we should be tax resident solely in Germany for the purposes of the convention between the Federal Republic of Germany and the Netherlands for the avoidance of double taxation with respect to taxes on income of 2012, or the German-Dutch tax treaty.
Our sole tax residency in Germany for purposes of the German-Dutch tax treaty is subject to the application of the provisions on tax residency as stipulated in the German-Dutch tax treaty as amended from time to time. The Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting or the MLI, Germany and the Netherlands entered into, among other countries, should not, as of this date, affect the German-Dutch tax treaty’s rules regarding tax residency.
The applicable tax laws, tax treaties or interpretations thereof may change, including the MLI choices and reservation. Furthermore, whether we have our place of effective management in Germany and are as such solely tax resident in Germany is largely a question of fact and degree based on all the circumstances, rather than a question of law, which facts and degree may also change. Changes to applicable laws or interpretations thereof and changes to applicable facts and circumstances (for example, a change of board members or the place where board meetings take place), or changes to applicable tax treaties, including a change to the application of the MLI may result in us becoming a tax resident of a jurisdiction other than Germany. As a consequence, our overall effective income tax rate and income tax expense could materially increase, which could have a material adverse effect on our business, results of operations, financial condition and prospects, which could cause our share price and trading volume to decline.
We believe it is likely that we were a PFIC for U.S. federal income tax purposes in 2021, 2022 and 2023, and we may be a PFIC in one or more future taxable years. U.S. shareholders may be subject to adverse U.S. federal income tax consequences in 2023 and in any future taxable year in which we are a PFIC.
We believe it is likely that we are a PFIC for U.S. federal income tax purposes in 2021, 2022 and 2023 and we may be a PFIC in one or more future taxable years. In addition, we may, now or in the future directly or indirectly, hold equity interests in other PFICs. Under the Code, we will be a PFIC for any taxable year in which, after the application of certain look-through rules with respect to subsidiaries, either (i) 75% or more of our gross income consists of passive income or (ii) 50% or more of the average quarterly value of our assets consists of assets that produce, or are held for the production of, passive income. Passive income includes, among other things, dividends, interest, certain non-active rents and royalties, and capital gains. It is possible that we will be a PFIC in any future taxable year because, among other things, (i) we own a substantial amount of passive assets, including cash and securities that may give rise to passive income, (ii) the valuation of our assets that generate non-passive income for PFIC purposes, including our intangible assets, is uncertain and may vary substantially over time and (iii) the composition of our income may vary substantially over time.
If we are a PFIC for any taxable year during which a U.S. investor holds ordinary shares, we would continue to be treated as a PFIC with respect to that U.S. investor for all succeeding years during which the U.S. investor holds ordinary shares, even if we ceased to meet the threshold requirements for PFIC status, unless certain exceptions apply. Such a U.S. investor may be subject to adverse U.S. federal income tax consequences, including (i) the treatment of all or a portion of any gain on disposition as ordinary income, (ii) the application of a deferred interest charge on such gain and the receipt of certain dividends and (iii) compliance with certain reporting requirements.
For further discussion, see “ITEM 10. ADDITIONAL INFORMATION —5. Taxation — Material U.S. Federal Income Tax Considerations for U.S. Holders of Ordinary Shares.”
-45-
We may lose our foreign private issuer status which would then require us to comply with the Exchange Act’s domestic reporting regime and cause us to incur significant legal, accounting and other expenses
We are a foreign private issuer and therefore we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act applicable to U.S. domestic issuers. If in the future we are not a foreign private issuer as of the last day of the second fiscal quarter in any fiscal year, we would be required to comply with all of the periodic disclosure, current reporting requirements and proxy solicitation rules of the Exchange Act applicable to U.S. domestic issuers. In order to maintain our current status as a foreign private issuer, either (a) a majority of our ordinary shares must be either directly or indirectly owned of record by non-residents of the United States or (b)(i) a majority of our directors and executive officers may not be United States citizens or residents, (ii) more than 50% of our assets cannot be located in the United States and (iii) our business must be administered principally outside the United States. If we were to lose this status, we would be required to comply with the Exchange Act reporting and other requirements applicable to U.S. domestic issuers, which are more detailed and extensive than the requirements for foreign private issuers. We may also be required to make changes in our corporate governance practices in accordance with various SEC and stock exchange rules. The regulatory and compliance costs to us if we are required to comply with the reporting requirements applicable to a U.S. domestic issuer may be significantly higher than the costs we would incur as a foreign private issuer. As a result, we expect that a loss of foreign private issuer status would increase our legal and financial compliance costs and would make some activities highly time consuming and costly. These rules and regulations could also make it more difficult for us to attract and retain qualified directors.
If we ever pay dividends, we may need to withhold tax on such dividends payable to holders of our shares in both Germany and the Netherlands
We do not intend to pay any dividends to holders of our shares. However, if we do pay dividends, we may need to withhold tax on such dividends both in Germany and the Netherlands. As an entity incorporated under Dutch law any dividends distributed by us are subject to Dutch dividend withholding tax on the basis of Dutch domestic law. However, on the basis of the double tax treaty between Germany and the Netherlands, the Netherlands will be restricted from imposing dividend withholding tax if we continue to be a tax resident of Germany and our place of effective management is in Germany. However, Dutch dividend withholding tax is still required to be withheld from dividends if and when paid to Dutch resident holders of our shares (and non-Dutch resident holders of our shares that have a permanent establishment in the Netherlands to which their shareholding is attributable). As a result, upon a payment (or deemed payment) of dividends, we will be required to identify our shareholders in order to assess whether there are Dutch residents (or non-Dutch residents with a permanent establishment to which the shares are attributable) in respect of which Dutch dividend tax has to be withheld. Such identification may not always be possible in practice. If the identity of our shareholders cannot be determined, withholding of both German and Dutch dividend tax from such dividend may occur, upon a payment of dividends.
Furthermore, the withholding tax restriction referred to above is based on the current choices and reservation made by Germany under the MLI. If Germany changes its MLI choices and reservation, we may not be entitled to any benefits of the double tax treaty between Germany and the Netherlands, including the withholding tax restriction, as long as Germany and the Netherlands do not reach an agreement on our tax residency for purposes of the double tax treaty between Germany and the Netherlands, except to the extent and in such manner as may be agreed upon by the authorities. As a result, any dividends distributed by us during the period no such agreement has been reached between Germany and the Netherlands, may be subject to withholding tax both in Germany and the Netherlands.
In addition, a proposed law is pending before the Dutch parliament, namely the Emergency Act Conditional Exit Dividend Tax (Spoedwet conditionele eindafrekening dividendbelasting) which would, if enacted, impose, possibly with retroactive effect, a dividend withholding (exit) tax on certain deemed distributions if we cease to be a Dutch tax resident and become a tax resident of a jurisdiction that is not a member of the EU or the EEA, when such jurisdiction does not satisfy certain conditions. In some cases, we would have a right to recover the amount of tax from our shareholders when such shareholder is not entitled to an exemption.
-46-
Dividends distributed on our shares to certain related entities in low-taxed or non-cooperative jurisdictions might in the future become subject to an additional Dutch withholding tax on dividends, as of January 1, 2024
We have no plans to pay regular dividends on our ordinary shares. However, if we do pay dividends, under current Dutch tax law, dividends paid by us to holders of our shares could become subject to Dutch dividend withholding tax at a rate of 15% under the Dutch Dividend Withholding Tax Act (Wet op de dividendbelasting 1965), unless a domestic or treaty exemption or reduction applies; see “ITEM 10. ADDITIONAL INFORMATION — 5. Taxation — Material Dutch Tax Considerations.” As of January 1, 2024, a Dutch conditional withholding tax will be imposed on dividends paid to related entities in jurisdictions that have a corporate income tax rate below 9% (low-tax jurisdiction) or jurisdictions that are included on the EU’s blacklist of non-cooperative jurisdictions (non-cooperative jurisdictions for tax purposes). In addition, the conditional withholding tax on dividends may also apply in situations where artificial structures are put in place with the main purpose or one of the main purposes to avoid the conditional withholding tax or in the event of a hybrid mismatch. The conditional withholding tax will be imposed at the highest Dutch corporate income tax rate in effect at the time of the distribution (currently 25.8%). The conditional withholding tax on dividends will be reduced, but not below zero, by any regular Dutch dividend withholding tax withheld in respect of the same dividend payment. As such, based on the currently applicable rates, the overall effective tax rate of withholding the regular dividend withholding tax and conditional withholding tax will not exceed the highest corporate income tax rate in effect at the time of the distribution (currently 25.8%). As of January 1, 2024, the withholding tax rate on dividends paid to shareholders that are (A) entities related (gelieerd) to us and (B)(i) established in a low-taxing state or non-cooperative jurisdiction for tax purposes, (ii) a hybrid entity or reverse hybrid entity or (iii) interposed to avoid tax otherwise due by another entity, may rise from 15% to the highest corporate tax rate (currently 25.8%).
We are a Dutch public company with limited liability. The rights of our shareholders are different from the rights of shareholders in companies governed by the laws of U.S. jurisdictions and may not protect investors in a similar fashion afforded by incorporation in a U.S. jurisdiction
We are a public company with limited liability (naamloze vennootschap) organized under the laws of the Netherlands. Our corporate affairs are governed by our Articles of Association and by the laws governing companies incorporated in the Netherlands. However, there can be no assurance that Dutch law will not change in the future or that it will serve to protect investors in a similar fashion afforded under corporate law principles in the United States, which could adversely affect the rights of investors.
The rights of shareholders and the responsibilities of directors may be different from the rights and obligations of shareholders and board members in companies governed by U.S. law. In the performance of its duties, our executive officers and board of directors are required by Dutch law to consider the interests of our company, its shareholders, its employees and other stakeholders, in all cases with due observation of the principles of reasonableness and fairness. It is possible that some of these parties will have interests that are different from, or in addition to, your interests as a shareholder.
Provisions of our Articles of Association or Dutch corporate law might deter acquisition bids for us that might be considered favorable and prevent, delay or frustrate any attempt to replace or remove the members of our board of directors
Under Dutch law, various protective measures are possible and permissible within the boundaries set by Dutch law and Dutch case law. Our governance arrangements include several provisions that may have the effect of making a takeover of our company more difficult or less attractive. In this respect, our general meeting of shareholders granted the right to an independent foundation under Dutch law, or protective foundation, to acquire preferred shares pursuant to a call option agreement, or the call option agreement, entered into between us and such foundation. This call option under the call option agreement shall be continuous in nature and can be exercised repeatedly on multiple occasions.
-47-
If the protective foundation exercises the call option pursuant to the call option agreement, an amount of preferred shares up to 100% of our issued capital held by others than the protective foundation, minus one share, will be issued to the protective foundation. These preferred shares will be issued to the protective foundation under the obligation to pay up to 25% of their nominal value upon issuance. In order for the protective foundation to finance the issue price in relation to the preferred shares, the protective foundation is expected to enter into a finance arrangement with a bank. As an alternative to securing financing with a bank, subject to applicable restrictions under Dutch law, the call option agreement provides that the protective foundation may request us to provide, or cause our subsidiaries to provide, sufficient funding to the protective foundation to enable it to satisfy the payment obligation (or part thereof) in cash and/or to charge an amount equal to the payment obligation (or part thereof) against our profits and/or reserves in satisfaction of such payment obligation.
The protective foundation’s articles of association provide that it will promote and protect the interests of the company, the business connected with the company and the company’s stakeholders from time to time, and repressing possible influences which could threaten the strategy, continuity, independence and/or identity of the company or the business connected with it, to such an extent that this could be considered to be damaging to the aforementioned interests. These influences may include a third party acquiring a significant percentage of our ordinary shares, the announcement of an unsolicited public offer for our ordinary shares, shareholder activism, other concentration of control over our ordinary shares or any other form of undue pressure on us to alter our strategic policies. The protective foundation shall be structured to operate independently of us.
If the protective foundation were to exercise its call option, the preferred shares to be issued pursuant thereto would be issued against the obligation to pay up to 25% of their nominal value. The voting rights of our shares are based on nominal value and, as we expect our ordinary shares to trade substantially in excess of nominal value, preferred shares issued at 25% of their nominal value can carry significant voting power for a substantially reduced price compared to the price of our ordinary shares and thus can be used as a defensive measure. These preferred shares will have both a liquidation and dividend preference over our ordinary shares and will accrue cash dividends at a pre-determined rate. The protective foundation would be expected to require us to cancel its preferred shares once the perceived threat to the company and its stakeholders has been removed or sufficiently mitigated or neutralized. However, subject to the same limitations described above, the protective foundation would continue to have the right to exercise the call option in the future in response to a new threat to the interests of us, our business and our stakeholders from time to time.
In addition, certain provisions of our Articles of Association may make it more difficult for a third party to acquire control of us or effect a change in our board of directors. These provisions include: a provision that our directors are appointed on the basis of a binding nomination prepared by our board of directors which can only be overruled by a two-thirds majority of votes cast representing more than 50% of our issued share capital; a provision that our directors may only be removed by the general meeting of shareholders by a two-thirds majority of votes cast representing more than 50% of our issued share capital (unless the removal is proposed by the board in which case a simple majority of the votes can be sufficient); and a requirement that certain matters, including an amendment of our Articles of Association, may only be brought to our shareholders for a vote upon a proposal by our board of directors.
We are not obligated to and do not comply with all the best practice provisions of the DCGC. This may affect your rights as a shareholder
We are a Dutch public company with limited liability (naamloze vennootschap), and we are subject to the DCGC. The DCGC contains both principles and best practice provisions that regulate relations between the board of directors and the shareholders (such as the general meeting of shareholders). The DCGC is based on a “comply or explain” principle. Accordingly, companies are required to disclose in their annual reports, filed in the Netherlands, whether they comply with the provisions of the DCGC. If they do not comply with those provisions (for example, because of a conflicting Nasdaq requirement), the company is required to give the reasons for such non-compliance.
The DCGC applies to all Dutch companies listed on a government-recognized stock exchange, whether in the Netherlands or elsewhere, including Nasdaq. We do not comply with all the best practice provisions of the DCGC. This may affect your rights as a shareholder and you may not have the same level of protection as a shareholder in a Dutch company that fully complies with the DCGC.

Claims of U.S. civil liabilities may not be enforceable against us
We are incorporated under the laws of the Netherlands, and our headquarters are located in Germany. Substantially all of our assets are located outside the United States. The majority of our directors and executive officers reside outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon such persons or to enforce against them or us in U.S. courts, including judgements predicated upon the civil liability provisions of the federal securities laws of the United States.
There is no treaty between the United States and the Netherlands for the mutual recognition and enforcement of judgements (other than arbitration awards) in civil and commercial matters. Therefore, a final judgement for the payment of money rendered by any federal or state court in the United States based on civil liability, whether or not predicated solely upon the U.S. federal securities laws, would not be enforceable in the Netherlands unless the underlying claim is relitigated before a Dutch court of competent jurisdiction. Under current practice, however, a Dutch court will generally, subject to compliance with certain procedural requirements, grant the same judgement without a review of the merits of the underlying claim if such judgement (i) is a final judgement and has been rendered by a court which has established its jurisdiction vis-à-vis the relevant Dutch companies or Dutch company, as the case may be, on the basis of internationally accepted grounds of jurisdiction, (ii) has not been rendered in violation of principles of proper procedure (behoorlijke rechtspleging), (iii) is not contrary to the public policy of the Netherlands, and (iv) is not incompatible with (a) a prior judgement of a Netherlands court rendered in a dispute between the same parties, or (b) a prior judgement of a foreign court rendered in a dispute between the same parties, concerning the same subject matter and based on the same cause of action, provided that such prior judgement is capable of being recognized in the Netherlands. Dutch courts may deny the recognition and enforcement of punitive damages or other awards.
Moreover, a Dutch court may reduce the amount of damages granted by a U.S. court and recognize damages only to the extent that they are necessary to compensate actual losses or damages. Enforcement and recognition of judgements of U.S. courts in the Netherlands are solely governed by the provisions of the Dutch Code of Civil Procedure. Based on the foregoing, there can be no assurance that U.S. investors will be able to enforce any judgements obtained in U.S. courts in civil and commercial matters, including judgements under the U.S. federal securities.
The United States and Germany do not have a treaty providing for the reciprocal recognition and enforcement of judgements in civil and commercial matters. Consequently, a final judgement for payment or declaratory judgements given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not automatically be recognized or enforceable in Germany. German courts may deny the recognition and enforcement of a judgement rendered by a U.S. court if they consider the U.S. court not to be competent or the decision to be in violation of German public policy principles. For example, judgements awarding punitive damages are generally not enforceable in Germany. A German court may reduce the amount of damages granted by a U.S. court and recognize damages only to the extent that they are necessary to compensate actual losses or damages.
In addition, actions brought in a German court against us, our directors, our executive officers and the experts named herein to enforce liabilities based on U.S. federal securities laws may be subject to certain restrictions. In particular, German courts generally do not award punitive damages. Litigation in Germany is also subject to rules of procedure that differ from the U.S. rules, including with respect to the taking and admissibility of evidence, the conduct of the proceedings and the allocation of costs. German procedural law does not provide for pre-trial discovery of documents, nor does Germany support pre-trial discovery of documents under the 1970 Hague Evidence Convention. Proceedings in Germany would have to be conducted in the German language and all documents submitted to the court would, in principle, have to be translated into German. For these reasons, it may be difficult for a U.S. investor to bring an original action in a German court predicated upon the civil liability provisions of the U.S. federal securities laws against us, our directors, our executive officers and the experts named in this Annual Report.
Based on the lack of a treaty as described above, U.S. investors may not be able to enforce against us or directors, executive officers or certain experts named herein who are residents of or possessing assets in the Netherlands, Germany, or other countries other than the United States any judgements obtained in U.S. courts in civil and commercial matters, including judgements under the U.S. federal securities laws.

6. | General Risk Factors |
General economic, political and social conditions.
Our business and results of operations may be adversely affected by disruptions in the financial markets, changes to political and regulatory policies and economic conditions generally
General economic, political and social conditions affect the United States, Europe and other global markets and our business. In particular, U.S., European and other global markets, as well as our access to financing, may be affected by factors, including economic growth or its sustainability, persistent inflation, supply chain disruptions, employment levels, work stoppages, labor shortages and labor disputes, labor costs, wage stagnation, energy prices, oil, gas and fuel prices, fluctuations or other significant changes in both debt and equity capital markets and currencies, liquidity of the global financial markets, the growth of global trade and commerce, trade policies, the availability and cost of capital and credit (including as a result of increased interest rates) and investor sentiment and confidence. Additionally, global markets may be adversely affected by the current or anticipated impact of cyber incidents or campaigns, military conflict, including the Russia-Ukraine conflict as well as the Hamas-Israel conflict and rising tensions between China and Taiwan and the relationship between China and the United States, or other geopolitical uncertainty and instability. The ongoing spread of variants of infectious diseases, such as the COVID-19 virus, may interrupt, or delay, our clinical trial activities, regulatory reviews, manufacturing activities and supply chain. The COVID-19 outbreak delayed enrollment in our clinical trials due to prioritization of hospital resources towards the outbreak or other factors, and some patients may be unwilling to enroll in our trials or be unable to comply with clinical trial protocols if quarantines impede patient movement or interrupt healthcare services, which would delay our ability to conduct clinical trials or release clinical trial results and could delay our ability to obtain regulatory approvals and commercialize our product candidates. Any sudden or prolonged market downturn in the United States or elsewhere could adversely affect our business, results of operations and financial condition, including capital and liquidity levels.
Legal, regulatory or market measures to address environmental and other objectives may negatively affect our business or operations
Regulatory and legislative bodies in the United States, Europe and elsewhere continue to focus on environmental, social and governance, or ESG, matters including increasing attention on relating to climate change, greenhouse gas emissions, carbon taxes, emissions trading schemes, sustainable manufacturing, human rights and equity matters, and disclosure regarding the foregoing, many of which policies may be ambiguous, inconsistent, dynamic or conflicting. We expect to experience increased restrictions, compliance costs, legal costs and expenses related to such new or changing legal or regulatory requirements. Moreover, compliance with any such legal or regulatory requirements would require us to devote substantial time and attention to these matters. In addition, we may still be subject to penalties or potential litigation if such laws and regulations are interpreted or applied in a manner inconsistent with our practices. Additionally, we are subject to increased attention from the media, stockholders, activists and other stakeholders on climate change, social and sustainability matters, which could negatively affect our reputation or investor confidence.
We may not be able to maintain sufficient insurance to cover us for potential litigation or other risks
We may not be able to maintain sufficient insurance on commercially reasonable terms or with adequate coverage levels against potential liabilities we may face in connection with potential claims, which could have a material adverse effect on our business. We may face a risk of loss from a variety of claims, including related to securities, antitrust, contracts, cybersecurity, fraud and various other potential claims, whether or not such claims are valid. Insurance and other safeguards might only partially reimburse us for our losses, if at all, and if a claim is successful and exceeds or is not covered by our insurance policies, we may be required to pay a substantial amount in respect of such successful claim. Certain losses of a catastrophic nature, such as losses arising as a result of wars, earthquakes, typhoons, terrorist attacks or other similar events, may be uninsurable or may only be insurable at rates that are so high that maintaining coverage would cause an adverse impact on our business, our investment funds and their investments. In general, losses related to terrorism are becoming harder and more expensive to insure against. Some insurers are excluding terrorism coverage from their all-risk policies. In some cases, insurers are offering significantly limited coverage against terrorist acts for additional premiums, which can greatly increase the total cost of casualty insurance for a property. As a result, we, our products and their investments may not be insured against terrorism or certain other catastrophic losses.
-50-
Raising additional capital may cause dilution to our shareholders, restrict our operations or require us to relinquish rights to our technologies or product candidates
We expect our expenses may increase in connection with expansion of operations. To the extent that we raise additional capital through the issuance of ordinary shares, convertible securities or other equity securities, your ownership interest may be diluted, and the terms of these securities could include liquidation or other preferences and anti-dilution protections that could adversely affect your rights as an ordinary shareholder. In addition, debt financing, if available, may result in fixed payment obligations and may involve agreements that include restrictive covenants that limit our ability to take specific actions, such as incurring additional debt, making capital expenditures, creating liens, redeeming shares or declaring dividends, that could adversely impact our ability to conduct our business. In addition, securing financing could require a substantial amount of time and attention from our management and may divert a disproportionate amount of their attention away from day-to-day activities, which may adversely affect our management’s ability to oversee the development of our product candidates.
If we raise additional funds through collaborations or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.
We face substantial competition, which may result in others discovering, developing or commercializing products before or more successfully than we do, and reducing or eliminating our commercial opportunity
Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we, or any future collaborators, may develop. Our competitors also may obtain the FDA or other marketing approval for their products before we, or any future collaborators, are able to obtain approval for ours, which could result in our competitors establishing a strong market position before we, or any future collaborators, are able to enter the market.
Many of our existing and potential future competitors have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining marketing approvals and marketing approved products than we do, and may be able to reduce the price at which they sell their products. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly if acquired by, or through collaborative arrangements with, large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, the development of our product candidates.
The development and commercialization of new products is highly competitive. We expect that we, and any future collaborators, will face significant competition from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide with respect to any of our product candidates that we, or any future collaborators, may seek to develop or commercialize in the future. For example, other pharmaceutical companies may commence development efforts for product candidates targeting the same indications as vilobelimab, including PG and severe COVID-19 or any other indications we may target. For a detailed analysis of the competitive environment in which we operate, see “ITEM 4. INFORMATION ON THE COMPANY — 2. Business Overview — Competition.”
-51-
If any product liability lawsuits are successfully brought against us or any of our collaboration partners, we may incur substantial liabilities and may be required to limit commercialization of our product candidates
We face an inherent risk of product liability lawsuits related to the testing of our product candidates in seriously ill patients and will face an even greater risk if our product candidates are approved by regulatory authorities and introduced commercially. Product liability claims may be brought against us or our partners by participants enrolled in our clinical trials, patients, health care providers or others using, administering or selling any of our future approved products. If we cannot successfully defend ourselves against any such claims, we may incur substantial liabilities.
If any of our product candidates are approved for commercial sale, we will be highly dependent upon consumer perceptions of us and the safety and quality of our products. We could be adversely affected if we are subject to negative publicity associated with illness or other adverse effects resulting from patients’ use or misuse of our products or any similar products distributed by other companies.
Although we maintain product liability insurance coverage, this insurance may not fully cover potential liabilities that we may incur. The cost of any product liability litigation or other proceeding, even if resolved in our favor, could be substantial. We will need to increase our insurance coverage if we commercialize any product that receives marketing approval. In addition, insurance coverage is becoming increasingly expensive and difficult to obtain. If we are unable to maintain sufficient insurance coverage at an acceptable cost or to otherwise protect against potential product liability claims, it could prevent or inhibit the development and commercial production and sale of our product candidates, which could harm our business, financial condition, results of operations and prospects.
We may be unsuccessful in evaluating material risks involved in future acquisitions
We may, in the future, acquire companies, products and/or platforms that are complementary to our operational and customer needs. As part of the process, we may conduct business, legal and financial due diligence to identify and evaluate material risks involved in any particular transaction. Despite these efforts, we may be unsuccessful in ascertaining or evaluating all such risks. As a result, the intended advantages of any given acquisition may not be realized. If we fail to identify certain material risks from one or more acquisitions we may be exposed to significant costs and our business could be negatively impacted.
Cyber incidents or other failures in IT systems could result in information theft, data corruption and significant disruption of our business operations
We utilize information technology, or IT, systems and networks to process, transmit and store electronic information in connection with our business activities. As use of digital technologies has increased, cyber incidents, including deliberate cyber-attacks and attempts to gain unauthorized access to computer systems and networks, have increased in frequency and sophistication, both internal and those provided by third-party service provider. These threats pose a risk to the security of our systems and networks, the confidentiality and the availability and integrity of our data. The wars in Europe and in the Middle East, as well as the tensions between China and Taiwan may also result in heightened cybersecurity risk across our networks and platforms. We have implemented processes, procedures and internal control to mitigate cybersecurity risks and cyber intrusions and rely on industry accepted security measures and technology to securely maintain confidential and proprietary information maintained on our information systems. However, these measures, as well as our increased awareness of the nature and extent of a risk of a cyber-incident, do not guarantee that a cyber-incident will not occur or that our financial results, operations or confidential information will not be negatively impacted by such an incident, especially because cyber threats change frequently or are not recognized until launched and because cyber incidents can originate from a wide variety of sources. Similarly, there can be no assurance that our collaborators, CROs, third-party logistics providers, distributors and other contractors and consultants will be successful in protecting our clinical and other data that is stored on their systems.
-52-
If a cyber incident were to occur and cause interruptions in our operations or any destruction or loss, corruption or unavailability of data, it could result in loss or misappropriation of confidential information, including trade secrets, other intellectual property or financial information, and a material disruption of our development programs and business operations, any of which could lead to significant delays or setbacks in our research and other further development and commercialization of our product candidates. For example, the loss of clinical trial data from completed, ongoing or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Finally, there has been significant evolution and developments in the use of artificial intelligence technologies, such as artificial generative chatbots. We cannot fully determine the impact or cybersecurity risk of such evolving technology to our business at this time.
Any such cyber incident or destruction or loss of data could have a material adverse effect on our business and prospects. In addition, we may suffer reputational harm or face litigation or adverse regulatory action as a result of cyber incidents, including cyber-attacks or other data security breaches, and may incur significant additional expense to implement further data protection measures.
The legal and regulatory environment related to data privacy is becoming stricter, which could result in additional costs or changes to the manner in which we handle personal information, and a failure to comply with such laws or regulations, or to otherwise protect personal data in our possession or control, could result in fines, litigation, or other penalties as well as reputational damage
We are subject to laws, regulations, and contractual obligations related to privacy, data protection, information security, including (i) the EU General Data Protection Regulation, which came into effect on May 25, 2018, and which provides for greater penalties for noncompliance than previous European data protection laws, with potential fines of up to the greater of €20 million or 4% of total annual worldwide turnover and (ii) the California Consumer Privacy Act, which came into effect on January 1, 2020, and provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation.
As privacy, data protection and information security laws evolve and are implemented, interpreted and applied, our compliance costs may increase, particularly in the context of ensuring that adequate data protection and data transfer mechanisms are in place. Additionally, compliance with such obligations and regulations could significantly impact our current and planned privacy and information security practices, our collection, use, sharing, retention and safeguarding of personal data, and our current and planned business activities and operations. A failure to comply with such obligations or regulations could result in fines, litigation, or other penalties and adversely impact our reputation.
If our internal controls over financial reporting fail to be effective, such failure could result in material misstatements in our financial statements, cause investors to lose confidence in our reported financial and other public information and have a negative effect on the trading price of our ordinary shares
Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered in their implementation could cause us to fail to meet our reporting obligations. Section 404 of the Sarbanes-Oxley Act of 2002 requires management of public companies to develop and implement internal controls over financial reporting and evaluate the effectiveness thereof. If we fail to design and operate effective internal controls, it could result in material misstatements in our financial statements, impair our ability to raise revenue, result in the loss of investor confidence in the reliability of our financial statements and subject us to regulatory scrutiny and sanctions, which in turn could harm the market value of our ordinary shares.
Banking system risk
We regularly maintain cash balances at third-party financial institutions in excess of the FDIC or other comparable foreign country (i.e., Germany) deposit insurance limits. If any banks or financial institutions at which we maintain cash balances enter receivership or become insolvent in the future in response to financial conditions affecting the banking system and financial markets, our ability to access our existing cash, cash equivalents and investments, or to draw on our existing lines of credit, may be threatened and could have a material adverse effect on our business and financial condition.

ITEM 4. INFORMATION ON THE COMPANY
A. | History and development of the company |
We are a biopharmaceutical company pioneering anti-inflammatory therapeutics by targeting the complement system. We do this by applying our proprietary technologies to discover, develop and commercialize first-in-class, highly potent and specific inhibitors of the complement activation factor known as C5a and its receptor C5aR. The complement system is an integral part of the innate immune system and protects the body, for example by recognizing and removing bacteria, viruses, and other infectious agents, collectively referred to as pathogens. Terminal complement activation, to which the cleavage of C5 by C5-convertases is also referred to, leads to the release of C5a, which acts through its receptor C5aR. In addition, terminal complement activation, i.e., the cleavage of C5a from C5, can also be achieved directly through the extrinsic pathway by naturally occurring enzymes present throughout the body but not considered part of the complement system. With our therapeutic product candidates, we target C5a and its receptor C5aR to selectively inhibit the powerful inflammatory response observed in a wide variety of autoimmune and other inflammatory diseases elicited through C5a/C5aR activation.
Our lead product candidate, vilobelimab, is a novel intravenously delivered first-in-class anti-C5a monoclonal antibody that selectively binds to free C5a and has demonstrated disease-modifying clinical activity and tolerability in multiple clinical settings. We are and have been developing vilobelimab in a wide array of complement-mediated diseases with significant unmet medical need. These include pyoderma gangrenosum, or PG, a chronic inflammatory skin disorder for which we started a Phase III study with the first patient treated in November 2023, the treatment of critically ill COVID-19 patients, for which we concluded a Phase III study in March 2022 and subsequently were granted the EUA by the FDA in April 2023.
Up to November 2023, we were also developing vilobelimab in cutaneous squamous cell carcinoma, or cSCC, in which we were running a Phase II clinical study. We have also previously conducted Phase II studies with vilobelimab in other diseases, including hidradenitis suppurativa, or HS, a chronic debilitating systemic inflammatory skin disease and ANCA-associated vasculitis, or AAV, a rare and life-threatening autoimmune disease.
We are also developing INF904, an orally administered, small-molecule inhibitor of C5aR, for which we have completed Phase I study in healthy volunteers and plan to initiate Phase II clinical studies in the future. INF904 is a promising product candidate for being developed in several disease areas of inflammation, where orally available therapeutics are not available or do not meet the medical need. INF904 development will initially be targeted at chronic spontaneous urticaria, or CSU, and HS.
We are also developing IFX002, a life-cycle management product for vilobelimab, which is currently in advanced pre-clinical stage.
Our legal and commercial name is InflaRx N.V and we were incorporated under the laws of the Netherlands on June 6, 2017, and our headquarters, as registered with the local court of Jena, is located in Jena, Germany. InflaRx was founded in 2007 as InflaRx GmbH by Professor Niels Riedemann and Professor Renfeng Guo in Jena, Germany. Our agent for service of process in the United States is InflaRx Pharmaceuticals, Inc. located at 600 South Wagner Road, Ann Arbor, Michigan 48103. Our principal executive offices and laboratories are located in Winzerlaer Str. 2, 07745 Jena, Germany, telephone: (+49) 3641 508 180. We have additional offices in Planegg-Martinsried (Munich), Germany and in Ann Arbor, Michigan, United States, where we also have laboratories.
We employ a total of 66 employees, 22 of whom have M.D. or Ph.D. degrees. Our management team has extensive experience in the field of complement research, clinical research and the biopharmaceutical industry. Both our Chief Executive Officer and founder, Professor (Dr.) Niels Riedemann, and our Chief Scientific Officer and founder, Professor Renfeng Guo, have over 20 years of complement research experience, having published extensively on the role and function of C5a and its receptors. Our Chief Financial Officer, Dr. Thomas Taapken, has served in executive positions and boards for various private and public European biotechnology companies over the last 19 years and has over 25 years total experience in managerial roles in the biopharmaceutical and venture capital industries. Our Chief Medical Officer, Dr. Camilla Chong, has 25 years of experience in the global pharmaceutical industry in the areas of clinical development, medical affairs, clinical operations, regulatory and pharmacovigilance as well as the launch of new medicines.

B. | Business overview |
Overview
C5a is a central mediator of the complement system and therefore a critical component of the innate immune system. The most prominent role of the complement system is to help the body defend itself against invading microorganisms through several mechanisms, including the rapid creation of an inflammatory environment and the production of factors that directly kill pathogens and recruit immune cells to sites of infection. Activation of the complement system ultimately results in the generation of C5a by cleavage from C5. C5a creates an inflammatory environment by attracting and strongly activating neutrophils as well as by causing many different cell types to generate pro-inflammatory molecules. Such inflammation normally benefits the body by helping to fight infection, but excessive or uncontrolled generation of C5a, as it occurs in certain diseases, can cause severe damage to the body’s own tissue, thereby contributing to the pathophysiology of many autoimmune and inflammatory diseases.
While the mode of action of C5a in inflammation has been intensely researched and confirmed, developing a highly specific antibody with the ability to fully block C5a while preserving a critical innate defense mechanism, the formation of the Membrane Attack Complex, or MAC, has been challenging. As such, there are currently no approved drugs that specifically target C5a. We identified antibodies, including our lead product candidate vilobelimab, that potently and selectively bind to a conformational epitope that is formed by C5a upon the cleavage of C5a from C5 that completely blocks C5a without compromising important upstream functions of the complement system, as well as MAC formation.
Unlike its ligand C5a, C5aR can also be pharmacologically inhibited by small molecules. It is generally believed that blockade of C5a using antibodies offers a fast, complete, and safe way to control C5a-induced inflammation. The advantage of a small molecule inhibitor to C5aR is that it can be administered orally, thereby offering broad, long-term ease of administration to patients, especially for the treatment of chronic diseases.
Through our in-house drug discovery efforts, we identified a potent inhibitor of the C5a receptor, INF904, which we believe is a promising candidate for development. We are currently developing INF904, an oral, low molecular weight drug candidate that targets the C5aR receptor. We plan on targeting complement-mediated, chronic auto-immune and inflammatory conditions where an oral small molecule is needed for patients.
Given the different advantages of blocking C5a and C5aR, we believe that the development of both, C5a and C5aR blocking agents is possible and potentially helpful to address a broader range of C5a/C5aR-molecular signaling axis-associated diseases.
Based on the broad anti-inflammatory properties, we are currently developing our lead anti-C5a antibody and our low molecular weight compound INF904 in several diseases. An overview can be found in the pipeline description below.

Vilobelimab for the treatment of PG
We are developing vilobelimab for the treatment of PG. PG is a rare, chronic inflammatory form of neutrophilic dermatosis characterized by accumulation of neutrophils in the affected skin areas. Vilobelimab was granted orphan drug designation for the treatment of PG by both the FDA in the United States and the EMA in Europe as well as fast track designation by the FDA. After a series of interactions with the FDA on the results of our successfully conducted Phase II clinical study and our plans for the further development towards a potential BLA submission, in 2023 we announced the start of a Phase III study with vilobelimab in ulcerative PG. In November 2023, we announced the enrollment of the first patient in the study.
Vilobelimab for the treatment of severe COVID-19
In April 2023, we received an EUA from FDA for GOHIBIC (vilobelimab) for the treatment of critically ill, invasively mechanically ventilated COVID-19 patients. The EUA is supported by the previously announced results of the multicenter Phase III PANAMO trial, which demonstrated a relative reduction in 28-day all-cause mortality by 23.9%. Subsequently, in June 2023, we began the commercialization of GOHIBIC (vilobelimab) in the United States under the EUA. Our MAA application for SARS-CoV-2 induced septic acute respiratory distress syndrome, or ARDS, receiving IMV or ECMO for vilobelimab is under regulatory review by the European Committee for Medicinal Products for Human Use, or CHMP, under the centralized procedure, which applies to all 27 member states of the EU. To support our development, we had received a total of €33.3 million as grant to us awarded by the German Federal Government for the period of October 2021 to June 2023.
Vilobelimab for the treatment of hidradenitis suppurativa, or HS
We have been developing vilobelimab for the treatment of HS. After having failed to meet our primary endpoint in an international Phase IIb study in 2019, in a post-hoc analysis of the study data we showed multiple signals of efficacy for the vilobelimab high dose group compared to the placebo group, demonstrating significant reductions in all combined inflammatory lesions, reductions of draining tunnels, or dTs, and reductions of the IHS4 score. Subsequently, we had several interactions with the FDA with the goal of agreeing on the possible design of a pivotal Phase III program for vilobelimab for the treatment of HS. Following the advice received in a Type A meeting with the FDA, in the fourth quarter of 2021, we submitted a full clinical trial protocol for the planned clinical Phase III trial of vilobelimab in HS and in January 2022 we initiated a randomized, double-blind, placebo-controlled, multi-center pivotal Phase III study to determine efficacy and safety of vilobelimab in patients with moderate to severe HS and active dTs with a modified primary clinical endpoint called m-HiSCR. Subsequently, the FDA provided conflicting advice to us, which was subsequently corrected, but in the meantime, we had halted the Phase III clinical program and are currently evaluating next steps regarding the development of vilobelimab in HS. Based on the logistical and financial effort necessary to successfully complete such a Phase III development program, we are assessing various future possible options to further this development, including collaborations with pharmaceutical partners.
Vilobelimab for the treatment of ANCA-associated vasculitis (AAV)
We have also been developing vilobelimab for the treatment of AAV. Our clinical development strategy for vilobelimab in AAV first focused on acutely ill AAV patients, where we believe vilobelimab has the potential to successfully induce remission and reduce or eliminate the need for high-dose corticosteroid, or HDCS, therapy and providing an improved safety profile. We also intend to focus on speed of induction of remission and reducing the rate of renal replacement and kidney dysfunction. After the successful completion of two Phase II studies in 2021, we are currently evaluating next steps regarding the development of vilobelimab in AAV. Based on the logistical and financial effort necessary to successfully complete a pivotal Phase III development program, we are currently assessing possible options to further this development including collaborations with pharmaceutical partners.
Anti-Ca5R inhibitor INF904
To expand the breadth of our anti-C5a/C5aR technologies, we are also developing INF904, a product candidate that targets the C5aR receptor. In INF904, we discovered a small molecule C5aR inhibitor that in pre-clinical studies has shown potential for superior characteristics to the only approved C5aR inhibitor, avacopan. INF904 has provided higher plasma exposure in animals, including non-human primates, and improved inhibitory activity in a hamster neutropenia model compared to avacopan. Furthermore, in contrast to avacopan, in vitro experiments showed INF904 has substantially less inhibition of the cytochrome P450 enzymes 3A4/5 (CYP3A4/5). INF904 demonstrated potential for anti-inflammatory therapeutic effects in several preclinical disease models. In January 2024, we announced the positive results of a single and multiple ascending dose study with INF904 in healthy volunteers. We plan to initiate Phase II clinical studies in the future. INF904 is a promising product candidate for being developed in several disease areas of inflammation, where orally available therapeutics are not available or a medical need exists despite availability of other therapies.

INF904 for the treatment of CSU
We also intend to pursue development of INF904 for the treatment of CSU. CSU is a debilitating and unpredictable skin disease characterized by intensely itchy hives / wheals and angioedema. The burden of this chronic disease is high and impacts sleep, mental health, quality of life and productivity due to absences from school and work. CSU is estimated to affect around 40 million people worldwide. CSU patients have been reported to show elevated C5a levels, a major activator of mast cells and basophils which are thought to be significant contributors to CSU pathogenesis. In addition, studies suggest that complement activation (including C5a) in CSU can lead to histamine release. Current treatments are limited, and a significant unmet need exists in a sizable proportion of patients.
INF904 for the treatment of HS
We also intend to pursue development of INF904 for the treatment of HS. HS is a chronic, recurrent, debilitating neutrophil-driven inflammatory disease that can persist for years and tremendously impacts quality of life; it is characterized by abscesses, nodules and draining tunnels which can flare and cause scarring. INF904 inhibits the known C5a-induced effects on neutrophil activation and tissue accumulation of immune cells, including generation of tissue damaging mechanisms (enzyme release and oxidative radical formation) as well as induction of NETosis – mechanisms thought to be involved in HS progression and draining tunnel formation. Clinical evidence with existing C5a/C5aR products also supports that blocking this pathway reduces lesion counts. Patients’ responses to treatment with approved anti-TNF-alpha or anti-IL17 drugs are known to wane over time in a significant number of cases; and treatment with new mechanisms are needed for these patients.
Anti-C5a antibody IFX002
We are also developing IFX002 for the treatment of chronic inflammatory diseases. IFX002 is a highly potent anti- C5a antibody, which binds to the same domain of the C5a protein as vilobelimab, but which has a higher humanization grade and altered pharmacokinetic properties compared to vilobelimab. IFX002 is currently in preclinical development. We consider IFX002 to be a life-cycle management product to vilobelimab, given the long remaining patent life of IFX002.
Vilobelimab for the treatment of cutaneous squamous cell carcinoma (cSCC)
We have been developing vilobelimab for the treatment of PD-1 / PD-L1 inhibitor resistant / refractory locally advanced or metastatic cSCC. We have been recruiting patients in two independent arms, vilobelimab as monotherapy and in combination with pembrolizumab. The main objectives of the trial were to assess the safety and antitumor activity of vilobelimab monotherapy and to determine the maximum tolerated or recommended dose, safety and antitumor activity in the combination arm in order to evaluate and establish the safety of vilobelimab in cSCC patients. The initial treatment responses of the study were encouraging. However, in view of the recent emergence of new alternative treatments for cSCC and the recommendation by our U.S. and international clinical experts to change course and to study additional patients with a higher dose of vilobelimab as monotherapy in a larger cohort, we have decided to cease the development in cSCC for the time being to prioritize our efforts and to reallocate our resources towards the development of our orally available C5aR inhibitor INF904. Nonetheless, patients who are currently in treatment will be treated for up to 24 months according to the protocol. However, we will not enroll any new patients in the study and we will close clinical sites in which no patients are being treated. Our decision to wind down this clinical study does not preclude us from considering the development of vilobelimab or INF904 in this or similar oncological indications in the future.

Our technology
C5a is a central mediator of the complement system and therefore a critical component of the innate immune system. The most prominent role of the complement system is to help the body defend itself against invading microorganisms through several mechanisms, including the rapid creation of an inflammatory environment and the production of factors that directly kill pathogens and recruit immune cells to sites of infection. Activation of the complement system ultimately results in the generation of C5a by cleavage from C5. C5a creates an inflammatory environment by attracting and strongly activating neutrophils as well as by causing many different cell types to generate pro-inflammatory molecules.
The complement system and role of the C5a/C5aR axis as critical component in the immune system and the need for control
The complement cascade consists of approximately 30 interacting proteins and forms a critical component of the innate immune system. This system protects the body, for example by recognizing and removing bacteria, viruses and other infectious agents, collectively referred to as pathogens. Activation of the complement system leads to a series of enzyme-like reactions that produce factors that both directly kill pathogens and recruit immune cells to sites of infection. This activation can be triggered via three major pathways: the classical pathway, the mannose binding lectin, or MBL, pathway and the alternative pathway. Activation of any pathway will lead to the cleavage of C3 and formation of C5-convertases. Terminal complement activation, which is also referred to as cleavage of C5, can be achieved by these C5 convertases. In addition, terminal complement activation can also be achieved directly through the extrinsic pathway by naturally occurring enzymes present throughout the body but not considered part of the complement system.
-57-
Cleavage of C5 results in the generation of C5a and C5b, two molecules with distinct biological activities. C5a is a strong inflammatory amplifier that exerts its biological functions by binding to two different receptors, C5aR and C5L2. C5b on the other hand assembles with C6, C7, C8 and many C9 molecules to form the MAC, an important intrinsic defense mechanism that causes the membranes of microorganisms to become permeable, leading to their disintegration, or lysis.
Overview of critical functions of the complement system
The complement system serves many crucial functions within the innate immune response, such as:
● | Rapid creation of an inflammatory environment. Production of pro-inflammatory molecules, such as C5a, optimizes the conditions under which enzymatic and other processes can act against microorganisms. These inflammatory conditions include the onset of a fever or release of aggressive enzymes and oxygen radicals by neutrophils. |
● | Lysis of microorganisms through formation of the MAC. A rapid, first-line defense mechanism resulting in the formation of pores in the cell membranes of invading microorganisms, leading to their disintegration. |
● | Bridge to the adaptive immune system. This function is promoted by an activation product of C3, called C3b, which tags particles and makes them visible and more easily processed by immune stimulatory cells. Such cells then present these particles to B-cells, which in turn generate antibodies against the particles, leading to targeted elimination. This mechanism takes a few weeks to take full effect. |
● | Clearance of dead cell particles. The complement system also serves various other purposes, including the clearance of dead cell particles from the body. This function is especially important because uncleared cell particles are believed to potentially induce generation of antibodies against normal cells and tissues, leading to autoimmune inflammatory responses and diseases. |
Need for control
Complement activation is a double-edged sword: the fast acting and relatively non-specific functions of pro-inflammatory responses driven by C5a and the lysis of microorganisms through MAC formation are usually very tightly controlled. However, inappropriate activation of the system can quickly turn it from a beneficial defense system into an uncontrolled inflammatory response. C5a’s uncontrolled activity in certain disease states can generate an inflammatory environment within the body that results in tissue damage and promotes pro-inflammatory T-cell autoimmune responses. The resulting tissue damage is believed to critically contribute to the disease progression of many acute as well as chronic inflammatory and autoimmune diseases, particularly during flare-up phases. Examples of this include Lupus disease, inflammatory bowel disease and neutrophil-driven diseases.
Despite the MAC’s role as a rapid, first-line defense mechanism, MAC formation can also result in damage to our body’s cells in some diseases. Normally, the body’s cells and tissues are protected from MAC-mediated lysis through surface inhibitors that prevent MAC formation. However, in paroxysmal nocturnal hemoglobinurea, or PNH, the patients’ cells lack the ability to hold MAC inhibitors on their cell surface, resulting in extreme susceptibility to MAC-related cell lysis. In addition, patients with diseases involving the kidney endothelial cells, such as atypical hemolytic uremic syndrome and certain forms of glomerulonephritis, also often appear to be burdened by MAC-related damage. Blockade of MAC formation in these very rare diseases can be lifesaving.
-58-
While blockade of MAC formation can be beneficial in certain circumstances, substantially blocking MAC formation can also result in susceptibility to life-threatening infections. For example, patients dosed with drugs that block MAC formation, such as with the marketed antibody eculizumab, must be immunized against meningococcal disease, which also carries the risk of side effects. Therefore, it is desirable to leave MAC formation intact when blocking complement-mediated damage in the broad variety of diseases in which an uncontrolled inflammatory response, and especially C5a, has been described as key driver of the damage.
We believe that C5a is a key inflammatory mediator driving tissue damage in many inflammatory diseases and thus represents a very meaningful drug target with large therapeutic potential. Therefore, we have conducted substantial research since our inception to generate highly specific antibodies targeting only C5a while leaving MAC formation intact, to deliver an ideal therapeutic approach for this attractive target.
Mechanisms of C5 activation
C5 can be produced by many cells, including epithelial cells of various organs, T-cells and other immune competent cells. Terminal C5 activation does not require activation of the three complement pathways and related formation of C5-convertases. Other enzymes can also directly cleave and activate C5, such that functionally active C5a can be generated in the complete absence of other complement components. For example, in the absence of other complement factors in the cell culture, lung epithelial cells can generate C5 upon stimulation, and lung macrophages can cleave and activate C5, leading to generation of C5a. This example illustrates that C5 can be activated and C5a can be generated independently from the complement pathways.
We further demonstrated that direct enzymatic cleavage of C5 occurs uninhibited in the presence of eculizumab, a known C5 inhibitor that binds to the MG-7 domain of C5 and hinders the C5 convertases from engaging and binding to C5. This research suggests that direct enzymatic cleavage of C5a from C5 works through a mechanism that is not blocked by C5 inhibitors such as eculizumab. Our studies further demonstrate that patients sufficiently dosed with eculizumab may still display elevated plasma C5a levels, implying that C5 inhibitors like eculizumab are not capable of fully blocking and controlling the C5a signaling pathway. Therefore, in diseases in which it plays a key promoting role, we believe targeting C5a directly may yield a meaningful therapeutic benefit.
C5a and its role in disease and inflammation
C5a is a small, 74-amino acid-spanning protein whose biochemical and immunological properties have been well documented in the scientific literature. C5a creates an inflammatory environment by attracting and strongly activating neutrophils as well as by causing many different cell types to generate pro-inflammatory and inflammation-related molecules. While this can help the body to respond strongly and rapidly to infections by optimizing the defense environment, uncontrolled C5a generation can induce damage to the body’s tissues in a broad variety of diseases. As a result, we believe that controlling and limiting C5a generation in the body may prevent the negative effects of an over-activated C5a immune response.
C5a quickly interacts with at least two independent receptors—C5aR and C5L2 (sometimes referred to as C5aR2). C5aR and C5L2 serve as a large signaling pool for effects elicited by C5a. C5aR has been well characterized as a signaling receptor that can be strongly upregulated in almost any cell across a variety of disease settings. Although less understood, C5L2 has also been shown to promote inflammation and negatively affect outcomes in various experimental disease settings by promoting the adverse effects, or AEs, elicited by uncontrolled C5a. Importantly, various other complement activation products (e.g., C3a, C3a-desArg and C4a) have been shown to bind to C5L2 and elicit effects different from those elicited by C5a. Thus, blocking specifically C5a as achieved by use of vilobelimab will eliminate only C5a mediated effects.
Role of C5a in neutrophil-driven inflammatory diseases
In the inflammatory response, C5a is an accelerator or “booster” of inflammation. This role of C5a extends to a broad variety of responses, including the following mechanisms:
● | C5a boosts the generation of many different cytokines such as IL-8, IL-6, IL17, TNF-alpha and others in a variety of cell types as well as within the bloodstream; |
● | C5a induces a complex change in the cell-signaling cascade of immune-competent cells that leads to an altered and often intensified signal transduction of other known signaling stimuli, such as the toll-like receptor signaling; |
● | C5a affects T-cell responses and causes a pro-inflammatory response, leading to the generation of further pro-inflammatory cytokines; and |
● | C5a is capable of inducing adhesion molecule expression on the surfaces of blood vessels, leading to neutrophil adherence to the internal vessel wall and migration through the vessel to the site of infection. |
-59-
When C5a binds to its receptors on neutrophils, they are strongly activated and move to the source of damage or infection, through a process referred to as chemotaxis, generating oxygen radicals and activated enzymes both believed to be major contributors to cellular and tissue damage in the body. In addition, C5a has been suggested to induce neutrophil extracellular trap, or NET, formation and a process in which neutrophils undergo a certain form of cell death while forming NETs called Netosis, which is believed to cause additional inflammation and damage in the tissue. Given this central function, C5a is a powerful tool that, when inappropriately activated, is capable of promoting damage to the body, ultimately leading to organ dysfunction and failure.
Neutrophil activation is assessed by observing the upregulation of the neutrophil surface marker CD11b (an established method to demonstrate neutrophil activation). In studies conducted in 2013 and 2014 as part of an investigative project in collaboration with an investigator from the University of Athens, we found that CD11b, as a marker for neutrophil activation, was greatly enhanced in fresh human whole blood from healthy volunteers when either recombinant human C5a was added or when plasma from hidradenitis suppurativa patients was added. Vilobelimab, our highly specific anti-C5a antibody, completely inhibited neutrophil activation resulting from the addition of the HS plasma, suggesting that C5a may be the key mediator in plasma from patients affected by this disease, leading to neutrophil activation.
Flow cytometry assay in fresh human whole blood demonstrating CD11b increase on blood neutrophils as marker of neutrophil activation: recombinant human C5a strongly activates human neutrophils in whole blood (huPP-ctr + 20 nM rhC5a), which can be fully blocked by addition of vilobelimab (“IFX-1” in the above graph) (huPP-ctr + 20 nM rhC5a + 20 nM vilobelimab) (open white bars). Plasma from two different HS patients (pat088 and pat092) also activates human neutrophils in whole blood and this effect can be fully blocked by the addition of vilobelimab (middle and darker grey bars) thus implying that C5a in HS patient plasma is the key neutrophil activating factor.
Various chronic inflammatory and autoimmune diseases in humans are characterized by flare-up phases during which substantial tissue damage occurs. Given C5a’s numerous inflammatory promoting functions, blocking it in chronic inflammatory diseases may have a positive effect on T-cell function, overall control of the inflammatory status of the disease and a strong anti-inflammatory effect on neutrophils, which may reduce tissue damage during the flare-up phases. Multiple international research groups have demonstrated in various inflammatory animal models that blocking the C5a/C5aR signaling axis leads to reduced inflammation, improved organ performance and favorable outcomes on clinical endpoints, including improved mortality rate, disease severity or damage scores.
C5a also has been described as a potential disturbing factor for a balanced T-cell response by down-regulating regulatory T-cells and promoting pro-inflammatory T-cell responses. Research published in 2013 in Nature Immunology and the Journal of Experimental Medicine demonstrated that blocking the C5a/C5aR signaling axis in mice restored regulatory T-cell function, inhibiting the progression of induced autoimmune diseases. Therefore, C5a is a potential drug target for the treatment of autoimmune and chronic inflammatory diseases associated with T-cell imbalance.
Role of C5a in cancer growth and metastatic disease
Different cancer cells have been found to generate their own C5a when cultured in vitro in the absence of any other complement factors or intact complement pathways. This result is possible because cancer cells produce C5, together with enzymes to directly cleave C5, thereby generating functionally active C5a. Recent research suggests that C5a contributes to cancer growth and metastatic disease, with multiple mechanisms proposed in the literature to explain this phenomenon. C5a appears to be associated with the recruitment and activation of myeloid-derived suppressor cells, or MDSCs, in tumors. Activating MDSCs suppresses the important T-cell-mediated mechanisms that usually inhibit tumor growth. Recently published findings in Cancer Cell in 2018 confirmed this mode of action that has been suggested in earlier published work. In addition, C5a generates a microenvironment favorable for tumor growth by increasing angiogenesis and enhancing the expression of the checkpoint molecule PDL1, as well as other mediators that enable tumor growth. These and other existing data may explain why combined therapy of anti-PD-1/PD-L1 and C5a blockade has been shown to effectively reduce tumor growth and metastasis in a pre-clinical mouse model.

Role of C5aR as potential target for therapeutic intervention
Two C5a receptors, C5aR (also known as C5aR1 or CD88) and C5aR2 (also known as C5L2 or GPR77), mediate the biological activities of C5a. Activation of C5aR has broadly acknowledged proinflammatory effects, while the role of activation of C5aR2 remains less well understood and recent scientific work has suggested a potential regulatory role on C5aR1 activation. In animal models of sepsis, anti-C5a treatment ameliorated the development of inflammatory responses and improved survival. In addition, experimental evidence suggests that blockade of C5aR signaling similarly improves survival in animals with sepsis. Finally, C5aR antagonists have shown excellent therapeutic effects in numerous models of inflammatory diseases involving complement activation.
Unlike its ligand C5a, C5aR can be pharmacologically inhibited by small molecules. In October 2021, avacopan, an oral C5aR antagonist, received market approval in the United States as an adjunctive treatment in adults for severe active ANCA-associated vasculitis (specifically MPA and GPA) in combination with standard therapy including glucocorticoids.
It is generally believed that blockade of C5a using antibodies offers a fast, complete, and safe way to control C5a-induced inflammation. The advantage of a low molecular weight compound inhibitor to C5aR is that it can be administered orally, thereby offering broad, long-term ease of administration to patients.
Our proprietary anti-C5a/C5aR technologies and product candidates
Our anti-C5a technology
Despite C5a’s well-characterized role in promoting inflammation and related tissue and organ damage in different diseases, no marketed drug targeting C5a exists. Based on more than 17 years of research in this field, we believe the challenge in targeting C5a is to fully block the biological functions of C5a in its natural environment and leave MAC formation intact. We believe our proprietary anti-C5a technology enables us to overcome this challenge through our discovery of a novel epitope, or binding site, on C5a. We believe this conformational epitope is formed only after the cleavage of C5a from the C5 molecule, suggesting that the three-dimensional structure of C5a changes upon release from C5, creating new epitopes that are only present on the free C5a molecule. This permits binding to free C5a only after it is cleaved from C5 and thus allows blocking of C5a while keeping MAC formation intact. We believe that this represents a breakthrough in the field of terminal complement C5a inhibition and that this may be particularly valuable when treating diseases that are driven by C5a, such as PG and severe COVID-19, cSCC, HS, AAV and others.
We identified antibodies, including our lead product candidate vilobelimab, that potently and selectively bind to a conformational epitope that is formed by C5a upon the cleavage of C5a from C5 to completely block C5a without compromising important upstream functions of the complement system, as well as MAC formation. We intend to discover and develop treatments leveraging our proprietary anti-C5a technology to address a wide array of complement-mediated diseases with significant unmet needs.
A conformational epitope on the surface of the C5a molecule allows for generation of highly specific blocking antibodies directed against C5a.
-61-
Our anti-C5a monoclonal antibodies are designed to have the following properties:
● | Complete immunological blockade and inhibition of C5a-induced effects: The human body has an abundant capacity to generate C5a, and induce inflammatory effects through its two receptors, C5aR and C5L2. Therefore, our anti-C5a antibodies are designed to: |
o | generate complete immunological blockade of the C5a molecule to achieve potent and effective treatments. Antibodies or inhibitors lacking this quality may leave a “signaling gap” for C5a, which, in a disease setting, will likely be sufficient to allow for strong pro-inflammatory effects. This signaling gap would limit the ability to silence the C5a/C5aR and C5a/C5L2 signaling axis to achieve the desired therapeutic effect; and |
o | bind with high affinity to C5a to counteract the molecule’s rapid interactions with its two receptors, C5aR and C5L2, which are abundantly present on the vast majority of cell types in the human body and that can be upregulated in various disease settings. |
● | Limited effect on MAC formation: C5 blocking molecules that inhibit MAC formation in the blood increase the risk of life-threatening infections caused by encapsulated bacteria such as meningococci. Therefore, leaving MAC formation intact may offer a significant advantage in C5a driven diseases. |
We believe that all these features are necessary for any drug targeting C5a, in order to achieve clinically meaningful pharmacological performance for the treatment of C5a-driven diseases such as PG, severe COVID-19, cSCC or others. Furthermore, we believe that C5a-driven diseases may not be effectively targeted with complement inhibitory approaches that do not specifically and fully block C5a. These approaches such as blocking the complement pathway-driven cleavage of C5 or inhibiting the complement pathways upstream of C5, are characterized by two fundamental shortcomings set forth below.
● | Inability to fully block C5a without targeting it directly: C5a can be generated through C5 activation by various enzymes in the complete absence of the complement pathways. For example, blocking the complement C5-convertase-driven cleavage with the C5 inhibitor eculizumab cannot block direct enzymatic C5 activation and C5a generation in an experimental setting. This may explain why elevated C5a levels remain measurable in patients effectively dosed with eculizumab. Therefore, non-specific approaches that do not bind and inhibit C5a directly may fail to fully block its effects. |
● | Lack of control over C5a’s signaling ability: C5a receptors are abundantly present on the majority of cells in humans and can be strongly and rapidly upregulated in certain disease states. As such, even with low levels of C5a, the receptors create a large “signaling sink” providing an abundant ability for even small amounts of C5a to transmit a signal. Therefore, a fully blocking targeted C5a approach is warranted in order to achieve full control over C5a-induced signaling events that may be especially important in highly acute inflammatory settings. |
Vilobelimab as first-in-class anti-C5a monoclonal antibody
Our lead product candidate, vilobelimab, is an intravenously delivered monoclonal anti-C5a antibody. It is based on our proprietary anti-C5a technology and was the first C5a monoclonal antibody to enter clinical development. Vilobelimab is differentiated by its ability to:
● | fully inhibit C5a-induced signaling and derived biological functions, as evidenced by its ability to completely prevent C5a-induced neutrophil activation in human whole blood; and |
● | leave MAC formation intact, as evidenced by testing the intact complement pathway driven MAC formation on red blood cells, leading to the lysis of these cells. |
-62-
We completed one placebo-controlled, single-center Phase I study of vilobelimab in healthy volunteers and completed two double-blind, placebo-controlled, multi-center Phase IIa studies in two acute care indications, early septic organ dysfunction and complex cardiac surgery. We also completed a Phase IIa and a Phase IIb clinical study in HS, two Phase II studies in AAV, a Phase IIa study in PG and a Phase II/III clinical study in critically ill, mechanically ventilated COVID-19 patients.
In all completed studies, vilobelimab was observed to be well tolerated. The placebo-controlled, multi-center Phase IIa studies in the two acute care indications demonstrated that vilobelimab blocked C5a with high statistical significance (p-values < 0.001) and that MAC formation, as demonstrated by a CH50 assay (as described below), in the groups treated with vilobelimab was not influenced, with mean CH50 values for treatment groups and control groups within the normal range.
To determine whether data is statistically significant, we use a “p-value,” which represents the probability that random chance could explain the results. The FDA utilizes the reported statistical measures when evaluating the results of a clinical trial, including statistical significance as measured by p-value as an evidentiary standard of efficacy, to evaluate the reported evidence of a product candidate’s safety and efficacy. If not otherwise specified, we used a conventional 5% or lower p-value (p < 0.05) to define statistical significance for the clinical trials and studies and data presented in this Annual Report.
Based on our clinical trials completed to date as well as the results from an EpiScreen ex vivo immunogenicity T-cell response assay, we believe that vilobelimab carries a low risk of provoking an immune response following administration. The immunogenicity assay used peripheral blood mononuclear cells from 21 donors and tested how many donors’ cells showed a CD4+ T-cell response following introduction of vilobelimab ex vivo. A response rate of over 10% (or more than three out of 21) means the applicable protein is considered to be high risk for immunogenicity, while a response rate of less than 10% means the protein is considered to be low risk. The results of the assay for vilobelimab showed that zero out of the 21 donors had a T-cell response rate, as compared to a control arm (using the A33 antibody), which showed a 30% response rate. In addition, based on an ADA detection assay conducted in connection with our Phase IIb clinical trial in HS, 10% of patients had ADAs at any time during the study. Only one participant the presence of ADAs was associated with any specific AE pattern indicating symptoms possibly related to the presence or emergence of ADAs leading to an immune reaction.
We are currently evaluating vilobelimab in various disease indications. In all ongoing and completed clinical studies so far, we have never observed effects that would raise doubts on the established safety of vilobelimab as a therapeutic drug candidate.
We will also continue to assess the potential for development of vilobelimab in other disease settings where we believe an anti-C5a antibody could be successfully developed into a marketed therapy.
Development of small molecule inhibitors of C5aR
Two C5a receptors, C5aR (also known as C5aR1 or CD88) and C5aR2 (also known as C5L2 or GPR77), mediate the biological activities of C5a. Activation of C5aR has broadly acknowledged proinflammatory roles, while activation of C5aR2 remains less well understood and recent scientific work has suggested a potential regulatory role on C5aR activation. C5aR is a G-protein-coupled-receptor expressed primarily by granulocytes, and, especially under disease conditions, broadly in various tissues and other immune cell types, which mediates the pathophysiological effects of C5a.
In animal models of sepsis, anti-C5a treatment ameliorated the development of inflammatory responses and improved survival. In addition, experimental evidence suggests that blockade of C5aR signaling similarly improves survival in animals with sepsis. Unlike its ligand C5a, C5aR can also be pharmacologically inhibited by low molecular weight compounds.
-63-
Low molecular weight C5aR antagonists have shown excellent therapeutic effects in numerous in vitro and in vivo animal models of inflammatory diseases involving complement activation. The advantage of a low molecular weight inhibitor of C5aR is that it can be administered orally, thereby offering broad, long-term ease of administration to patients, especially for the treatment of chronic diseases. Through proper clinical investigation of these small molecule C5aR antagonists in diseases induced by the activation of C5a/C5aR axis, the safety and efficacy of these agents can be established.
Avacopan is the first oral C5aR antagonist, which has market approval in the United States as an adjunctive treatment in adults for severe active ANCA-associated vasculitis (specifically MPA and GPA) in combination with standard therapy, including glucocorticoids.
Through our in-house drug discovery efforts, we identified a potent inhibitor of the C5a receptor, INF904, which we believe is a promising candidate for development. We are currently developing INF904, an oral, low molecular weight drug candidate that targets the C5aR receptor. We plan on targeting complement-mediated, chronic auto-immune and inflammatory conditions where an oral small molecule is needed for patients.
Given the different advantages of blocking C5a and C5aR, we believe that the development of both C5a and C5aR blocking agents is possible and potentially helpful to address a broader range of C5a/C5aR-molecular signaling axis-associated diseases.
Our preclinical and clinical development programs
Vilobelimab for the treatment of PG
We are developing vilobelimab for the treatment of PG. PG is a rare, chronic inflammatory form of neutrophilic dermatosis characterized by accumulation of neutrophils in the affected skin areas. The exact pathophysiology is not fully understood, but it is postulated that inflammatory cytokine production as well as neutrophil activation and dysfunction contribute to a sterile inflammation in the skin. PG often presents as painful pustule or papule, mainly on the lower extremities, which can rapidly progress to an extremely painful enlarging ulcer. Associated symptoms include fever, malaise, weight loss and myalgia. PG usually has a devastating effect on a patient’s life due to the severe pain and induction of significant movement impairment depending on lesions’ location. The exact prevalence of PG is not yet known but is estimated that up to 51,000 patients in the United States and Europe are affected by this disease.
There are 4 disease types recognized: ulcerative (the classical variant, which is the focus of our development), bullous (atypical), pustular, and vegetative (superficial, granulomatous). The ulcerative variant is the most frequent and typical form of PG, with lesions predominantly on the lower extremities.
There are currently no drugs approved for the treatment of PG in the US or in Europe. The only locally approved treatment is adalimumab, which has been approved in Japan but in no other country. There is no established standard of care based on controlled studies in PG. However, due to the high medical need associated with the disease, certain drugs are used in medical practice as treatment attempts for affected patients. These include certain orally administered drugs such as immunosuppressants, including cyclosporine or corticosteroids which are sometimes also used concomitantly, as well as topically applied drugs such as tacrolimus and others. Lastly intravenously administered TNF-alpha inhibitors such as infliximab or adalimumab or other biological drugs are also used as treatment attempt, despite the fact that no formal regulatory approvals are in place.
In February 2019, we initiated an open label, multi-center Phase IIa exploratory study enrolling 19 patients with moderate to severe PG in Canada, the United States and Poland. The objectives of this study were to evaluate the safety and efficacy of vilobelimab in this patient population in three different doses and to determine the appropriate dose for the future development of vilobelimab in registrational Phase III studies for the treatment of PG.
-64-
In April 2021, the study reached its enrollment target with 19 patients. In October 2021, we announced preliminary results from the study. In the third dosing cohort at 2400mg biweekly, six of the seven patients achieved clinical remission with a PGA score of ≤ 1, which reflected a closure of the target ulcer. All patients in the third dosing cohort had elevated C5a levels at baseline that were continuously suppressed after initiation of treatment with vilobelimab.
From all three dose cohorts in the study, two patients had related SAEs that were reported: one patient experienced an erysipelas leading to hospitalization (judged as non-drug related by sponsor), another developed a rash due to a delayed hypersensitivity reaction and withdrew from study. No dose-related AEs were found. Overall, the observed AE profile was in line with the underlying disease.
Final results from all patients were presented at the American Academy of Dermatology Association, AAD, Annual Meeting in March 2022 in an oral late-breaker session by Afsaneh Alavi, MD, Associate Professor of Dermatology, Mayo Clinic. The reported final results showed a dose-dependent effect in the highest dose cohort of 2400 mg, confirming the preliminary results with six out of seven patients showing a clinical remission (Physician Global Assessment, or PGA, score ≤ 1) and closure of the target ulcer in this dose cohort. The seventh patient showed a slight improvement (PGA score 4) with a decrease of the target ulcer area of over 50%. During the follow-up period, ulcers remained closed two months after treatment completion in all but one patient, and a sustained suppression of C5a was observed for up to 20 days after the last dosing.
With these results, vilobelimab was granted orphan drug designation for the treatment of PG by both the FDA in the United States and the EMA in Europe as well as fast-track designation be the FDA. Furthermore, we announced that we had a productive end-of-phase II meeting with the FDA related to our plans for a Phase III development program in PG in June 2022. In January 2023, we announced details related to the design of our planned Phase III study with vilobelimab in ulcerative PG.
The Phase III study is designed to enroll patients in the United States, Europe and selected countries in other regions. The study design is based on detailed feedback and recommendations from the FDA Division of Dermatology and Dentistry and was developed in close collaboration with the Company´s advisors from the United States, Europe and other regions. The multi-national, randomized, double-blind, placebo-controlled Phase III trial has two arms: vilobelimab (2,400mg every other week) plus a low dose of corticosteroids and placebo plus the same low dose of corticosteroids. In both arms, corticosteroid treatment will be initiated on day one and will be tapered off within the first eight weeks of the treatment period. The primary endpoint of the study will be complete closure of the target ulcer at any time up to 26 weeks after initiation of treatment. Treatment will be discontinued for patients whose disease progresses or fails to improve at defined time points during the study. The study has an adaptive trial design with an interim analysis blinded for the sponsor and investigators (but unblinded for the independent data safety monitoring committee), which is planned upon enrollment of approximately 30 patients, divided equally between the two arms of the study. The interim analysis with a set of predefined rules will take into account the then-observed difference in complete target ulcer closure between the two arms and will then determine whether the trial sample size will be adapted or whether the trial should be stopped due to futility. The enrollment period is projected to last at least two years, and its overall period will depend on the total trial size after sample size adaptation.
In November 2023, we announced the enrollment of the first patient in the trail.
Vilobelimab for the treatment of critically ill, invasively mechanically ventilated COVID-19 patients
Severe COVID-19 is characterized by severe lung inflammation and activation of coagulation, frequently requiring mechanical ventilation while the patient is in the intensive care unit. Mortality and morbidity rates are high among critically ill, invasively mechanically ventilated patients with COVID-19, despite the established broad use of corticosteroids and other anti-inflammatory agents. Poor disease outcomes have been associated with activation of the complement system, specifically the C5a/C5aR molecular signaling axis. Experimental studies in other viral lung diseases have shown that C5a is a potent anaphylatoxin, attracting neutrophils and monocytes to the site of infection that causes tissue damage, endothelialitis, and micro- thrombosis. Mouse studies also showed that blockade of the C5a/C5aR1 molecular signaling axis limits the infiltration of myeloid cells in damaged organs and prevents excessive lung inflammation and endothelialitis.

Despite wide-spread use of vaccines against SARS-CoV-2 and improvement in disease management, including use of immune modulators like anti-IL6 antibodies or JAK inhibitors, glucocorticosteroids and anti-coagulant therapy during the recent COVID-19 pandemic, mortality rates of critically ill, intubated and mechanically ventilated patients have remained at levels over 50%. With 450 to 3,800 COVID-19 related fatalities per week in the United States throughout 2023, according to the Centers of Disease Control and Prevention, or CDC, (https://covid.cdc.gov/covid-data-tracker/#trends_weeklydeaths_select_00 ) this indicates the still prevailing medical need for effective therapies for the treatment of these patients.
During the COVID-19 pandemic of 2020-2023, it became clear that effective therapies for the treatment of severely or critically ill COVID-19 patients were not available or had not tested for this indication. In an effort to provide a contribution to this medical emergency and based on our existing pre-clinical research on the role of C5a in viral-induced pneumonia, we decided to initiate a clinical development program with vilobelimab in critically ill COVID-19 patients with severely progressed pneumonia.
Clinical development
In March 2020, we initiated a randomized open label multi-center trial Phase II/III clinical development program with vilobelimab in severe COVID-19 patients with severely progressed pneumonia. In the Phase II part of the study, we evaluated vilobelimab treatment plus best supportive care compared to best supportive care alone for up to 28 days. Relative change (%) from baseline to day 5 in oxygenation index (defined as PaO2/FiO2 ratio) was assessed as the primary endpoint along with additional clinical parameters until day 28. In the study, patients were randomized to two treatment arms, either Arm A, best supportive care and vilobelimab or Arm B, best supportive care alone. The primary endpoint was the relative percentage change from baseline to day 5 in the oxygenation index (PaO2 / FiO2).
On June 17, 2020, we announced results from the Phase II part of the study. A total of 30 patients were randomized in the trial, and 15 patients were treated in each arm: vilobelimab plus best supportive care or best supportive care alone. Over a treatment period of 28 days, patients in the vilobelimab arm received a maximum of seven doses of 800 mg vilobelimab intravenously on separate days. At randomization, 18 patients were intubated (60%), and 12 patients (40%) had other oxygen supply. A higher number of patients with two or more comorbidities associated with increased COVID-19 mortality were reported in the vilobelimab treatment group compared to best supportive care group. Relative change in the oxygenation index at day 5 showed no differences between treatment groups. However, vilobelimab treatment was associated with a lower 28-day all-cause mortality when compared to the best supportive care group, along with trends in disease improvement, as evidenced by fewer patients experiencing renal impairment assessed by estimated glomerular filtration rates, more patients showing reversal of blood lymphocytopenia and a greater lowering of lactate dehydrogenase concentrations. In vilobelimab-treated patients, pulmonary embolisms reported as SAEs occurred less compared to the best supportive care arm. Also, a temporary increase of D-dimer levels, as potential expression of induction of blood clot lysis, was detected in the first days after initiation of vilobelimab treatment. Twenty-eight-day all-cause mortality in the vilobelimab treatment group was 13% (2 out of 15) versus 27% (4 out of 15) in the control group. In the best supportive care group, four patients died of COVID-19-induced multi-organ failure, and three of them had pulmonary embolisms reported as a SAE. In the vilobelimab arm, one patient died after an acute ventilator tube complication (leakage) and one patient with a history of severe chronic obstructive pulmonary disease died of pulmonary failure.
SAE rates were comparable between groups, but the rate of pulmonary embolisms reported as SAEs was substantially lower in the vilobelimab treatment group. Upon review of the safety data, the independent data safety monitoring board recommended continuation of the trial into the Phase III part.
In the Phase III part of the study, from September 2020 to October 2021, we enrolled 369 mechanically ventilated patients with COVID-19 across sites in the European Union, South America and other regions. Patients were randomized 1:1 to receive either vilobelimab or placebo; most patients received standard of care (97% glucocorticosteroids, 98% anti-thrombotic agents). The primary endpoint is 28-day all-cause mortality; key secondary endpoints include assessment of organ support and disease improvement.
-66-
In March 2022, we announced that the Phase III part of the Phase II/III PANAMO study with mechanically ventilated COVID-19 patients was successfully completed and showed a relative reduction in 28-day all-cause mortality of 23.9% (p = 0.094). At the recommendation of regulatory authorities during the course of the trial, we changed the statistical analysis method for the primary endpoint. The original protocol specified a non-stratified Cox regression analysis, and the final statistical analysis plan specified a site-stratified analysis intended to account for the site stratification of patients at randomization. The original protocol specified analysis would have resulted in a p-value of 0.027 (statistically significant), whereas the site-stratified Cox regression led to a p-value of 0.094 (not statistically significant). Additionally, pre-specified logistic regression analyses of the 28-day mortality resulted in p-values of <0.05 for three out of the four pre-specified analyses. Furthermore, a pre-specified analysis of patients from Western European countries (n=209) showed a relative reduction in 28-day all-cause mortality of 43% (vilobelimab 21.2% versus placebo 37.2%, hazard ratio: 0.5, p=0.014), suggesting an improvement in mortality in line with the reported Phase II data of the PANAMO Phase II/III study.
Regulatory activities
In September 2022, we announced the submission for EUA following encouraging interactions with the FDA at a Type B meeting held in summer 2022. Additionally, we were granted fast track designation from the FDA for vilobelimab for the treatment of critically ill, intubated, mechanically ventilated COVID-19 patients.
In April 2023, the FDA issued the EUA for GOHIBIC (vilobelimab) for the treatment of COVID-19 in hospitalized adults when initiated within 48 hours of receiving IMV or ECMO.
In July 2023, we submitted a Marketing Authorization Application (MAA) for SARS-CoV-2 induced septic ARDS receiving IMV or ECMO to the EMA. In August 2023, the EMA validated the MAA. This means that the application is now under regulatory review by the CHMP under the centralized procedure, which applies to all 27 member states of the European Union.
To achieve full commercial scale and successfully reach the full market potential of the product in the future, we also aspire to obtain full market approval for Gohibic (vilobelimab). We are therefore planning the submission of the BLA for full approval of Gohibic (vilobelimab) in our COVID-19 indication and potentially, in the future, in similar indications that may apply to other virally induced acute respiratory distress conditions. In October 2023, in furtherance of our continued efforts to obtain a BLA, we had an encouraging Type C meeting with the FDA. In that meeting, the FDA indicated their willingness to collaborate with us in identifying a development pathway towards a BLA for a broader ARDS label. To achieve this, we would need to conduct an additional well-controlled and adequately powered study in a broader ARDS setting that demonstrates the safety and efficacy of vilobelimab. During the meeting, we discussed different options for such a trial, including potential trial designs, patient population and trial power aspects.
We are actively evaluating and working towards next steps to enable such a trial in a broader ARDS setting and are currently exploring different funding options, including government grants as well as collaborations with third parties.
Commercialization
We intend to seek full marketing authorization in major markets, including the United States and Europe. For this we might hire experts in sales and marketing and build the necessary commercial and logistical infrastructure internally and/or with the potential assistance of external service providers. In parallel, we also intend to seek partners to support our commercialization, such as partnerships in select regions and potentially building commercial infrastructure in other regions if EUA is granted.
In June 2023, we began the commercialization of GOHIBIC (vilobelimab) in the United States for the treatment of COVID-19 in hospitalized adults when initiated within 48 hours of receiving IMV or ECMO. We entered into agreements with certain subsidiaries of Cencora Inc., or Cencora (formerly known as AmerisourceBergen Corp.) to act as our U.S. distributor and to make GOHIBIC (vilobelimab) available for order by U.S. hospital customers under the EUA. Cencora provides cold storage, cold-chain distribution services, inventory management and secondary labeling/packaging, among other services. To support our commercial efforts, we have hired and are continuing to hire U.S. experts with relevant experience in the commercialization of medical products in the hospital market, including in the areas of sales, sales operations, marketing, market access, distribution, medical affairs and others. In addition, we are expanding the necessary infrastructure, including IT systems, supply chain, financial reporting systems and inventory management systems both, internally and with the assistance of external service providers.
-67-
As we expand our commercial efforts, we continue to enhance our commercial strategic plan, further expanding our sales force and medical affairs teams, preparing relevant promotional and medical education materials to target healthcare providers and other stakeholders, refining our medical affairs strategy to increase awareness of the EUA among the medical community, and initiating our sales efforts.
In July 2023 and subsequently in October 2023, the NIH published and subsequently updated their guidelines for the treatment of COVID-19 patients. The NIH guidelines stipulate that there is insufficient evidence to recommend either for or against the use of vilobelimab for the treatment of critically ill COVID-19 patients. This neutral NIH guideline recommendation has negatively affected the commercial adoption of GOHIBIC (vilobelimab) as many healthcare providers, particularly hospitals, rely on NIH treatment guidelines when drafting their formularies and placing new orders. We believe that the NIH analysis does not take into account positive factors that the FDA considered in granting the EUA, and we are working to provide as much scientific evidence as possible to the NIH and others in the medical community with the goal of reaching concurrence of the NIH guideline committee position with the detailed published FDA review and thus reconsidering their recommendation for the treatment of critically ill COVID-19 patients with Gohibic (vilobelimab).
Governmental funding
In October 2021, we announced that we received a grant of up to €43.7 million from the German Ministry of Education and Research and the German Ministry of Health to support our development of vilobelimab for the treatment of severe COVID-19 patients. Due to subsequent changes in our research and development plan and fewer costs projected within the timeframe of the grant, we were notified that the amount available to us is €41.4 million. The grant is structured as a reimbursement of 80% of certain pre-specified expenses related to the clinical development and manufacturing of vilobelimab. The grant period ended on June 30, 2023. In total, during the duration of the grant period through December 31, 2023, we received €33.3 million to support our activities regarding the development of vilobelimab as a new therapeutic agent for the treatment of critically ill COVID-19 patients and for the establishment of a commercial scale manufacturing process to ensure the ability of being able to provide such treatment to the broader population.
Vilobelimab for the treatment of cSCC
Cutaneous squamous cell carcinoma, or cSCC, is the second most common skin cancer. The incidence of cSCC increases with increasing sun exposure and age and individuals with fair skin and hair are more often affected. Approximately 200,000 to 400,000 cases of cSCC per year are being reported in the United States reaching up to estimates as high as 1 million per year. Estimates in Europe vary by geographic location from approximately 30 cases in 100,000 people per year in northern Europe to approximately 10 cases in 100,000 people in southern Europe. The incidence of cSCC is increasing around the world. However, advanced and metastatic forms of cSCC are rare. While treatment response rates of advanced and metastatic forms of cSCC with programmed cell death protein-1, or PD-1, / programmed death ligand-1, or PD-L1, inhibitors is believed to be in the range of 50%, patients frequently relapse, and resistant / refractory patients typically have a very poor prognosis.
The potential for local recurrence or metastasis of cSCC varies with the pathologic variant and localization of the primary lesion, and the risk for metastasis in cSCC is approximately 2-5%. Advanced cSCC 10-year survival rates are less than 20% with regional lymph node involvement and less than 10% with distant metastases. Patients with distant metastases have median survival times of less than 2 years.
We are also developing vilobelimab for the treatment of PD-1 / PD-L1 inhibitor resistant / refractory, locally advanced or metastatic cSCC. cSCC is the second most common skin cancer. The incidence of cSCC increases with cumulative sun exposure and age, and individuals with fair skin and hair are more often affected. The potential for local recurrence or metastasis of cSCC varies with the pathologic variant and localization of the primary lesion, and the risk for metastasis in cSCC is approximately 2%-5%. Advanced cSCC 10-year survival rates are less than 20% with regional lymph node involvement and less than 10% with distant metastases.

In the study, which was initiated in April 2021, we recruited patients in two independent arms, vilobelimab alone (Arm A) and vilobelimab in combination with pembrolizumab (Arm B). The main objectives of the trial are to assess the safety and antitumor activity of vilobelimab monotherapy, to determine the maximum tolerated or recommended dose in combination with pembrolizumab, as well as to evaluate the safety and antitumor activity in the combination treatment arm in cSCC patients.
As of the date hereof, 10 patients were enrolled in Arm A, in which they received a run-in dose of 800 mg of vilobelimab on days 1, 4, 8 and 15, followed by a dose of 1,600 mg vilobelimab every two weeks starting on day 22. An interim analysis in Arm A of the 10 patients was conducted in July 2023 and the treatment responses in Arm A were evaluated. The interim efficacy analysis showed that one patient had a complete response (CR) and one patient continued with stable disease according to the protocol and as per “Response Evaluation Criteria In Solid Tumors” (RECIST). The patient with the CR is still on treatment.
After five weeks of treatment with the first three patients in Arm A of the study, a safety assessment was successfully completed, and enrollment in Arm B was also opened.
In Arm B, as of the date hereof, three patients have been treated in the first dosing cohort of the study (400 mg intravenous infusions of vilobelimab on days 1, 4, 8 and 15 and 800 mg from day 22 and every two weeks thereafter, in addition to 400 mg of pembrolizumab on day 8 and every six weeks thereafter). Six patients were treated in the next higher (second) dose cohort (600 mg intravenous infusions of vilobelimab on days 1, 4, 8 and 15 and 1,200 mg from day 22 and every two weeks thereafter, in addition to 400 mg of pembrolizumab on day 8 and every six weeks thereafter). In the third dosing cohort, six patients were treated at the highest planned dose per protocol (800 mg intravenous infusions of vilobelimab on days 1, 4, 8 and 15 and 1,600 mg from day 22 and every two weeks thereafter, in addition to 400 mg of pembrolizumab on day 8 and every six weeks thereafter). Each dose escalation was done per recommendation and after review of the safety data by an independent Steering Committee comprised of external clinical advisors. In total, as of the date hereof, 15 patients were enrolled in Arm B (3+6+6 in the three dosing cohorts). Before proceeding with the second stage of the study in Arm B, the interim efficacy data as assessed in recent discussions with our panel of experts showed one patient with partial response from the second cohort, and one patient with partial response from the third cohort, who are still in treatment.
The treatment responses in the single dose Arm A and the initially observed results in the combination Arm B of the study were encouraging. However, in view of the recent emergence of new alternative treatments for cSCC and the recommendation by our U.S. and international experts to change course and to study additional patients with a higher dose of vilobelimab as monotherapy in a larger cohort, we have decided to cease the development in cSCC for the time being. While we remain interested in further understanding of the potential monotherapeutic effect of vilobelimab in this oncology indication, further research would require substantial resources and significantly extend the timeline of the ongoing clinical program. Therefore, in November 2023, we decided to prioritize our efforts and to reallocate our resources towards the development of our orally available C5aR inhibitor INF904.
Patients who are currently in treatment will be treated for up to 24 months according to the protocol. However, we will not enroll any new patients in the study and we will close clinical sites in which no patients are being treated. Our decision to wind down this clinical study does not preclude us from considering the development of vilobelimab or INF904 in this or similar oncological indications in the future.
Vilobelimab for the treatment of HS
HS is a chronic debilitating systemic skin disease that results in painful inflammation of the hair follicles, most notably in the armpit, groin and genital regions. The clinical hallmarks of this disease include very painful inflammatory nodules, boils or abscesses that typically open and release odorous inflammatory fluids. In the more chronic form of the disease, patients experience dTs (previously referred to as draining fistulas or sinus tracts), which ultimately lead to scarring and related functional disability in certain areas. HS patients suffer primarily from pain and significant discomfort resulting from the constant formation of pus, often requiring the use of bandages and diapers, resulting in social isolation. HS severely adversely affects patients’ quality of life. HS typically presents in the second and third decade of a patient’s life and often develops into a life-long debilitating chronic disease.
The target patient population for vilobelimab is HS patients displaying a moderate to severe form of the disease. In the United States, we estimate that moderate to severe HS has a prevalence of up to 200,000 patients, although recent publications suggest a higher prevalence. In Europe, the number of affected patients is also believed to be greater, with higher prevalence and incidence of HS in countries with warmer climates.
-69-
The accepted (but not approved) standard of care for HS patients includes topical, oral or intravenous antibiotic treatment, as well as surgery, which often provide only temporary symptomatic relief. HS is recognized as a systemic autoimmune disease, for which there are numerous suggested etiological factors, including genetics. Neutrophils are believed to play a potential disease-promoting role as well as certain cytokines and mediators commonly found in autoimmune diseases such as TNF-alpha, IL-17, IL-1 and others. C5a promotes inflammatory mediators and is a strong activator of neutrophils, which was the basis for our investigation of our C5a blocking drug candidate vilobelimab in patients with HS. We established that patients suffering from HS show proof of significant systemic complement activation with elevated plasma concentrations of C5a and other markers.
The only approved drug in the United States and in Europe to treat HS is adalimumab, an inhibitor of tumor necrosis factor-alpha, or TNF-alpha. Although it provides clinical benefit to a portion of moderate to severe HS patients, approximately 50% or more of the patients did not respond to adalimumab treatment. Therefore, a high unmet medical need among HS patients still persists.
The Hidradenitis Suppurativa Clinical Response, or HiSCR, score has been developed to assess the effectiveness of treatments for HS in clinical trials. Patients are defined as HiSCR responders when a ≥ 50% reduction in inflammatory lesion count, including abscesses and inflammatory nodules, or AN, is observed. At the same time, no increase in abscesses or dTs when compared with baseline shall be observed. The HiSCR is the primary endpoint that was used to support regulatory approval by the FDA and EMA of adalimumab for the treatment of HS patients.
In contrast to the dichotomous nature of the HiSCR, the IHS4 score was developed to score severity and track treatment response in a continuous manner as an alternative to HiSCR. However, the IHS4 score has not yet been utilized as primary endpoint in late-stage clinical studies in HS. This composite score weights the most fluctuating inflammatory nodules with one point, abscesses with two points and dTs with four points.
We have been developing vilobelimab for the treatment of HS. Initially we evaluated vilobelimab in a Phase IIa, single center open-label study in 12 patients with severe HS, who had partly failed to respond to prior treatment attempts. Results from the trial demonstrated a HiSCR response in 75% of patients at the end of eight weeks of treatment and in 83% of patients at the end of the 12-week trial observation period, demonstrating initial clinical evidence of the product candidate’s disease-modifying effect. The results also demonstrated that vilobelimab administration was well tolerated, with no drug-related adverse events detected and no infusion-related, allergic or anaphylactic reactions were observed.
Subsequently, we completed a larger multi-center, international Phase IIb study (SHINE) to determine the efficacy and safety of vilobelimab in moderate to severe HS patients. The trial was a randomized, double-blind and placebo-controlled, multi-center study with five dose groups, including one placebo group. After a placebo-controlled double-blind period of 16 weeks, each patient received vilobelimab open label for additional 28 weeks to assess long-term efficacy and safety. The main objective of the study was to evaluate a dose response signal assessed by the HiSCR score at week 16 as the primary endpoint.
In June 2019, we announced the top-line results of the international SHINE Phase IIb study, in which we failed to meet our primary endpoint utilizing HiSCR at week 16. The randomized, double-blind, placebo-controlled, multi-center study enrolled a total of 179 patients in four active dose arms and a placebo arm at over 40 sites in 9 countries in North America and Europe. While the highest dose (1200mg every two weeks) led to a 45.5% reduction in HiSCR, the placebo response amounted to 47.1% on the HiSCR endpoint. No difference could be detected in treatment-emergent AEs between placebo and vilobelimab treatment groups.
In a subsequent post-hoc analysis published in July 2019, we showed multiple signals of efficacy for the vilobelimab high dose group compared to the placebo group, demonstrating significant reductions in all combined inflammatory lesions, reductions of dT counts and reductions of the IHS4 score. For example, at week 16, a statistically significant reduction of dT count relative to baseline in the high dose vilobelimab group when compared to placebo could be observed (mean: -63.3% vs. -18.0%; p=0.0359; all patients with at least one dT at baseline).
-70-
In 2021 we submitted a Special Protocol Assessment, or SPA, to the FDA for the Phase III HS program for vilobelimab HS, suggesting IHS4 as the primary efficacy endpoint, which was subsequently declined by the FDA. The FDA agreed to the dosing regimen in the protocol but did not agree with the assessment of the primary endpoint using IHS4. We later held a Type A meeting with the FDA to align on the Phase III study design and a proposed new primary endpoint instead of IHS4. The discussion focused on reaching consensus on the overall study population and the primary endpoint measure. In September 2021, we announced the outcome of this meeting in which the FDA was supportive of the proposed pivotal study program focusing on patients with active dTs. The FDA also supported a new primary efficacy endpoint that would include measuring the reduction of all three inflammatory lesions associated with HS - inflammatory nodules, abscesses and dTs, called m-HiSCR (modified HiSCR). A m-HISCR responder is defined as, relative to baseline, at least a 50% reduction of ANdT count and at least a 50% reduction of dT count. The FDA provided advice on how to implement, name and validate the meaningfulness of the m-HiSCR for the intended patient population, especially since a reduction in dT count is not adequately captured by the HiSCR. Following the advice received in the Type A meeting, we submitted a full clinical trial protocol for the planned clinical Phase III trial of vilobelimab in HS patients with actively draining disease to the FDA. Upon submission of study protocol for review, we received no comments from FDA within the 30-day and 60-day review periods.
In January 2022, we initiated a randomized, double-blind, placebo-controlled, multi-center pivotal Phase III study to determine efficacy and safety of vilobelimab in patients with moderate to severe HS and active dTs with the m-HiSCR as primary endpoint. In February 2022, we paused the study after we receive an advice letter from the FDA that stated that the FDA recommended using the HiSCR as the primary endpoint in the Phase III trial. The FDA advice was provided nearly three months after our protocol submission and contrasted with the FDA advice provided to us in the Type A meeting held previously. However, the FDA did not issue a clinical hold. In March 2022, the FDA corrected its advice to us. In the corrected advice letter, the FDA stated that, contrary to its February 2022 advice letter, the FDA no longer recommended using the HiSCR as the primary endpoint for the chosen patient population, but gave recommendations related to implementation of the m-HiSCR endpoint. Subsequently, we halted the Phase III clinical program and are currently evaluating next steps regarding the development of vilobelimab in HS.
In February 2022, we also held a virtual research and development event in which we disclosed a post-hoc analysis of the m-HiSCR on the Phase IIb SHINE data (as shown below).
The data is consistent with the fact that in the Phase IIb SHINE study, significant reduction of dT count is only achieved within the high dose group.
Based on the logistical and financial effort necessary to successfully continue and complete a Phase III development program for vilobelimab in HS, we are currently evaluating options to further this development in the future, including with a potential pharmaceutical partner.

Vilobelimab for the treatment of anti-neutrophil cytoplasm antibody (ANCA) associated vasculitis
ANCA associated vasculitis, or AAV is a rare, life-threatening autoimmune disease with a relapsing nature, characterized by necrotizing vasculitis, an inflammation of blood vessels. The disease is characterized by life-threatening flare phases affecting the kidney function and other organs leading to organ dysfunction and failure, a potentially fatal outcome unless treated appropriately. AAV predominantly affects small vessels associated with anti-neutrophil cytoplasmic antibodies, or ANCA. It comprises three disease entities: GPA, or granulomatosis with polyangiitis (known as Wegener’s Granulomatosis); MPA, or microscopic polyangiitis; and EGPA, or eosinophilic granulomatosis with polyangiitis (known as Churg-Strauss syndrome).
AAV is designated as an orphan disease and affects approximately 40,000 and 75,000 patients in the United States and Europe, respectively. In addition, AAV has a reported incidence of 4,000 and 7,500 new patients per year in the United States and Europe, respectively.
Because of the life-threatening character of this disease, it is crucial to induce remission rapidly when a flare presents. The treatment to induce remission differs from maintenance therapy. The current treatment regimen to induce remission uses a combination of High Dose Corticosteroids, or HDCS, together with either rituximab or cyclophosphamide. In addition, avacopan has recently been approved and may be added to these therapies. The long lasting HDCS therapy is associated with significant side effects and additional life-threatening risks for the patients.
The disease promoting role of C5a for AAV is well established. A priming effect of C5a for neutrophils appears to be the essential factor leading to neutrophil-related damage of the endothelial cells in the vessels. In addition, patients with acute AAV disease have significantly elevated complement activation parameters in their plasma when compared to AAV patients in remission. In an experimental AAV disease model in mice, it was shown that while C5aR deficiency leads to reduction in disease activity, C6 deficiency does not lead to such improvement, suggesting that MAC formation might not play a major role in this disease. However, additional research is warranted to confirm this conclusion.
We have also been developing vilobelimab for the treatment of AAV. Our clinical development strategy for vilobelimab in AAV first focused on acutely ill AAV patients, where we believe vilobelimab has the potential to successfully induce remission and reduce or eliminate the need for high-dose corticosteroid, or HDCS, therapy and providing an improved safety profile. We also intended to focus on speed of induction of remission and reducing the rate of renal replacement and kidney dysfunction.
In May 2021, we announced topline results from a randomized, triple blind, placebo-controlled Phase II clinical study with vilobelimab to evaluate the efficacy and safety in patients with moderate to severe AAV, in which 19 patients were enrolled at centers in the United States. Patients in all three groups received the standard of care dosing therapy consisting of rituximab or cyclophosphamide and were randomized to either receive a low dose of vilobelimab in combination with a standard dose of glucocorticoids, a high dose of vilobelimab in combination with a standard dose of glucocorticoids or placebo in combination with a standard dose of glucocorticoids. The primary endpoint of the study was the number and percentage of subjects who experience at least one treatment-emergent AE per treatment group at week 24. The key secondary endpoint of the study is a 50% reduction in Birmingham Vasculitis Activity Score, or BVAS, at week 16, a well-established endpoint that has been used in the previous AAV studies, along with clinical remission. Overall, vilobelimab was safe and well tolerated, as observed treatment-emergent AEs were reflective of the disease and SOC treatment. The proportion of patients achieving a clinical response was defined as a 50% reduction in BVAS at week 16 (and no worsening in any body system) compared to baseline, and clinical remission was defined as BVAS=0. Although the sample size of the trial was small and it is difficult to interpret results not powered to show statistical significance, patients across all three treatment groups demonstrated a strong response at week 16, and more patients treated with SOC plus vilobelimab had clinical remissions at various timepoints throughout the study compared to SOC plus placebo.
In November 2021, we announced topline results from a randomized, double-blind, placebo-controlled Phase II clinical study with vilobelimab to evaluate efficacy and safety in patients with moderate to severe AAV, in which 54 patients were enrolled at centers in Europe. The primary endpoint of the study was a 50% reduction in BVAS at week 16. Secondary efficacy endpoints being analyzed include clinical remission, evaluation of the Vasculitis Damage Index, or VDI, reduction of glucocorticoid toxicity index, or GTI, several relevant biomarkers like glomerular filtration rate, and patient reported outcomes. The study was conducted in two parts. In part 1, patients were randomized to receive either vilobelimab plus a reduced dose of glucocorticoids, or placebo plus a standard dose of glucocorticoids. In part 2 of the study, patients were randomized to receive either vilobelimab plus placebo, glucocorticoids or placebo plus a standard dose of glucocorticoids. Patients in both arms received standard of care immunosuppressive therapy, consisting of rituximab or cyclophosphamide. The study achieved its principal objective, demonstrating comparable clinical response of vilobelimab to standard of care, while significantly reducing the need for glucocorticoid (GC) treatment in this life-threatening indication. Clinical response as well as remission were achieved in comparably high rates in all three arms: clinical response at week 16 was observed in 16 out of 18 (88.9%) evaluable patients in the group receiving vilobelimab alone; in 22 out of 23 (95.7%) patients receiving SDGC; and in 10 out of 13 (76.9%) patients in the vilobelimab + RDGC group. The GTI composite score at week 16 was substantially lowered in the vilobelimab only group (mean value of 0.8) when compared to the SDGC group (mean value of 44.9) and the vilobelimab + RDGC group (mean value of 26.1). Assessment of the VDI at week 16 suggested comparable values between groups with the vilobelimab only group showing the lowest value: vilobelimab only group (1.0), SDGC group (1.5) and vilobelimab + RDGC group (1.9). eGFR, a secondary endpoint of the study, demonstrated no medically meaningful changes in all three arms. The vilobelimab only group had the lowest number of reported treatment-emergent AEs, as well as related treatment-emergent AEs.

We are currently evaluating next steps regarding the development of vilobelimab in AAV and are considering discussing the data from both the U.S. and EU studies with regulatory authorities before determining next steps. Based on the logistical and financial effort necessary to successfully complete a pivotal Phase III development program, we are currently assessing different options to further this development, including with a potential pharmaceutical partner.
Additional clinical and pre-clinical development for vilobelimab
Beyond PG, severe COVID-19, cSCC, HS and AAV, the indications we described in the above sections, we keep exploring the possibility to advance the clinical development of vilobelimab in additional inflammatory and chronic complement-mediated autoimmune disease indications for which a good pre-clinical or clinical proof of concept exists and where C5a has been demonstrated as a critical disease promoting factor or where similar mechanisms, such as neutrophil-driven systemic diseases affecting the skin and or other organs, are identified.
INF904 as orally administered low molecular weight molecule for inhibition of C5aR
Inhibition of the C5a/C5aR axis provides strong anti-inflammatory effects in a variety of diseases. Blockade of C5a using highly specific antibodies, such as vilobelimab, may offer a fast, effective, and safe way to control C5a-induced inflammation. In addition to this approach, inhibition of C5aR by oral small molecules may provide the ease of administration required for effective long-term treatment for more chronic inflammatory diseases. To expand the breadth of our anti-C5a/C5aR technologies, we are also developing INF904, an oral, small molecule drug candidate that targets the C5aR receptor. C5aR, a G-protein-coupled-receptor expressed primarily by granulocytes, mediates the pathophysiological effects of C5a. In INF904, we discovered a small molecule C5aR inhibitor that in pre-clinical studies has shown potential for superior characteristics to the only approved C5aR inhibitor, avacopan. INF904 has provided higher plasma exposure in animals, including non-human primates, and improved inhibitory activity in a hamster neutropenia model compared to avacopan. Furthermore, in contrast to avacopan, in vitro experiments showed INF904 has substantially less inhibition of the cytochrome P450 3A4/5 (CYP3A4/5) enzymes, which play an important role in the metabolism of a variety of drugs, including glucocorticoids. No obvious toxicological findings, even in the highest dose groups tested in required GLP toxicity analyses, were identified. INF904 demonstrated potential for anti-inflammatory therapeutic effects in several preclinical disease models.
All IND-enabling studies, including certain GLP-toxicological studies, have been completed, and we conducted a Phase I single and multiple ascending dose clinical study from November 2022 to January 2024.
In September 2023, we announced the topline results from the single ascending dose, or SAD part of a randomized, double-blind, placebo-controlled Phase I trial with INF904.
The SAD part of the Phase I first-in-human trial enrolled 62 healthy volunteers within six different dosing groups from 3 mg to 240 mg who were randomly assigned to receive INF904 or a placebo. Different drug concentrations were tested for the 60 mg dosing group. The main objectives were to assess safety and tolerability of single ascending doses under fasting conditions. Secondary endpoints included several pharmacokinetic, or PK, parameters, and the effect of INF904 on C5a-induced neutrophil activation in blood samples from treated volunteers ex vivo also was explored.
The results show that INF904 was well tolerated in treated patients and resulted in no safety signals of concern in single doses ranging from 3 mg to 240 mg. The overall percentage of adverse events (AEs) was lower in the INF904 treated patients compared to the placebo group, and no serious or severe AEs were observed at any dosing level. No related AEs were reported in conjunction with INF904 dosing.

Analysis of INF904 PK in subject plasma samples revealed sustained exposure to INF904 with six hours to maximum concentration, or tmax. INF904 plasma levels were dose proportional for systemic exposure (AUClast) and nearly dose proportional for maximum concentration (Cmax) over the dose range used in the study. With the 30 mg dose, INF904 reached a Cmax of 289 ng/ml with an AUClast of 5197 h.ng/ml, which are approximately 3-fold and 10-fold, respectively, higher than the published Phase I data from the only marketed comparator, avacopan.
Single doses of 30 mg or higher of INF904 achieved ≥90% blocking of C5a induced up-regulation of the activation marker CD11b on neutrophils in plasma samples from subjects ex vivo at 24 hours post dosing. This inhibition was achieved when 12.6 nM recombinant C5a was added as stimulus in this assay, a C5a concentration which can be observed in patients with severe inflammatory conditions such as the immuno-dermatological disease, hidradenitis suppurativa, or during life-threatening inflammation (e.g., in critically ill COVID-19 patients or septic patients). Thus, INF904 inhibition of C5a-induced neutrophil activation in human plasma achieved the set goal for effective C5aR control at disease relevant C5a levels.
In January 2024, we announced topline results from the multiple ascending dose, or MAD, part a randomized, double-blind, placebo-controlled Phase I trial for INF904. The PK and pharmacodynamic, or PD parameters confirm the favorable data we observed during the SAD part of the study, which provides support for the best-in-class potential of INF904. INF904 was well tolerated and there were no adverse safety events of concern after repeated dosing in participants over the entire tested dose range.
In the MAD part of the randomized, double-blind, placebo-controlled Phase I trial, 24 participants received multiple doses of INF904 for 14 days of either 30 mg once per day, or QD, 30 mg twice per day, or BID, or 90 mg BID. The study’s primary objective was to evaluate the safety and tolerability of repeated dosing. Several PK parameters were analyzed as secondary endpoints, and the effect of the dosing scheme on C5a-induced neutrophil activation in blood samples from the participants was also explored in an ex vivo assay.
The safety analysis of INF904 in the MAD part of the Phase I study demonstrated that it was well tolerated in participants over the entire dose range and resulted in no safety signals of concern. The overall percentage of AEs in INF904 treated participants was 77.8%, which was lower than the 83.3% observed in the placebo group. There were no serious or severe AEs observed at any dosing level.
Analysis of the PK profile showed that potential target AUC0-12h, Cmax, and trough values were achieved rapidly within 14 days of 30 mg BID dosing. INF904 exposure further increased proportionally with dosing up to 90 mg BID. These results were demonstrated even when participants ingested the drug in a fasted state, suggesting that food is not required to achieve potentially therapeutic drug levels.
Analysis of the PD profile showed that the blocking activity of C5a-induced neutrophil activation by INF904 reached equal to or above 90% over the 14-day dosing period for all tested doses in an ex vivo challenge assay where physiological and disease- relevant levels of C5a were added to blood samples provided by the trial participants.
In parallel, we have progressed with the development of a commercially viable formulation of INF904 which we plan to introduce into Phase II development towards the end of 2024.
We are currently conducting additional required pre-clinical studies, including long-term chronic toxicology studies, to enable longer-term dosing of INF904 for chronic inflammatory diseases. We currently plan to initiate a short-term dosing Phase II study towards the end of 2024, followed by a longer-term dosing Phase II study in 2025. We initially plan to develop INF904 for the treatment of two initial immuno-dermatology indications: HS and CSU.

IFX002 as follow-on anti-C5a monoclonal antibody product candidate
To expand the breadth of our anti-C5a technologies, we are also developing IFX002 for the treatment of chronic inflammatory indications. IFX002 is an advancement of the anti-C5a technology. It is a highly potent anti-C5a antibody with a higher humanization grade and altered pharmacokinetic properties and is currently in pre-clinical development.
IFX002 is an injectable product candidate with a prolonged blood plasma half-life than vilobelimab, making it potentially more amenable for the treatment of chronic inflammatory indications with less severe flares or closer to the onset of the disease. IFX002 shares the same mechanism of action as vilobelimab in its potential to block C5a with high specificity but is designed for a dosing regimen that may be more suitable for chronic therapy. Furthermore, IFX002 binds to the same epitope of free C5a as vilobelimab with comparable selectivity. The pre-clinical development of IFX002 was partly supported by a grant from the German government. IFX002 will keep the performance relevant properties to fully block C5a-induced biological effects while leaving MAC formation intact. We believe that IFX002 holds the potential to treat various chronic inflammatory diseases and could benefit from a dosing regimen more suitable for chronic therapy. We also consider IFX002 to be a life-cycle management product to vilobelimab, given the long remaining patent life of IFX002.
Pipeline
We intend to leverage our expertise within the complement field as well as our proprietary technologies to sustain our lead in the anti-C5a/anti-C5aR space by developing a diverse pipeline focused on complement-mediated autoimmune and inflammatory diseases with high unmet need. Rights to our proprietary anti-C5a/anti-C5aR technologies are currently expected to extend at least up to 2041 on the basis of our latest patents granted.
The figure below summarizes key information about and the development status of our current pipeline of product candidates:
Our strategy
Our goal is to maintain and further advance our leadership position within the anti-C5a/anti-C5aR complement space, delivering first-in-class autoimmune and anti-inflammatory therapies to market. To achieve this goal, we expect to execute the strategies set forth below.
● | Advance vilobelimab in PG. Based on the positively concluded open label Phase IIa study, we are conducting a Phase III pivotal clinical program after having received advice related to the clinical trial design from the FDA. |
-75-
● | Proceed with clinical development of INF904. We have conducted a single and multiple ascending dose study of our C5aR antagonist INF904 and currently are conducting additional required non-clinical studies to proceed to Phase II trials in patients. |
Continue to optimize the manufacturing process for vilobelimab. We established a fully validated manufacturing process for vilobelimab with an established and reputable CDMO with the goal of fulfilling the quality criteria to gain regulatory approval for such process. We are establishing the final manufacturing of the finished pharmaceutical product (i.e., “fill and finish”) in Germany and are considering the transfer of the drug substance manufacturing process from China to Germany or other countries.
Assess development options for vilobelimab in HS, cSCC and AAV. Following our decision to halt these development programs due to the resources required to conduct these on our own, we are currently evaluating options regarding the development of vilobelimab in HS, cSCC and AAV. Based on the logistical and financial effort necessary to successfully complete pivotal Phase III development programs in each of these indications, such options include potential collaborations with a pharmaceutical partner.
● | Pursue the further development of IFX002 to get prepared for potential clinical development. We are developing IFX002 as an injectable with a longer half-life than vilobelimab, making it suitable for chronic inflammatory indications with less severe flares or closer to the onset of disease. Based on a patent lifetime potentially beyond 2040, we see this project as life-cycle management for vilobelimab and are conducting pre-clinical development work to get closer to the possible start of clinical development. |
● | Solidify and continue to expand the breadth of our leadership position in the anti-C5a/anti-C5aR space by leveraging the full potential of our proprietary technologies and expertise in complement and inflammation research. We intend to continue to discover and develop treatments that have the potential to address a broad spectrum of complement-mediated or immune response mediated indications with significant unmet need, either internally or in collaboration with a partner. To accomplish this, we continue to supplement our research and development activities with our discovery unit in Ann Arbor, Michigan and we are further building out our intellectual property portfolio and our business development capabilities. |
Commercialize GOHIBIC (vilobelimab) under the granted EUA either independently or in collaboration with pharmaceutical partners. We are commercializing Gohibic (vilobelimab) for severe COVID-19 in the United States independently, and assessing the options to commercialize the drug in Europe independently or in collaboration with potential partners. We have employed a targeted commercial infrastructure to promote access to vilobelimab through centers-of-excellence that treat patients suffering from the disease in these core markets in US. Outside of the United States and Europe, we may pursue the approval and commercialization of vilobelimab for severe COVID-19 either independently or in collaboration with others. For other indications, we intend to develop and commercialize vilobelimab either independently or through collaborations with other parties.
Advance vilobelimab to market approval for severe COVID-19: continue the approval process of MAA by the EMA and for a full BLA submission to the FDA.
● | Explore the possibility to expand the applications of vilobelimab into related diseases. If we gain regulatory approval in the United States or in Europe for the use of vilobelimab in severe COVID-19, we intend to explore the possibility of expanding the label into other critical care indications for which we have generated pre-clinical data in the past. Most notably, we may consider additional studies, potentially in collaboration with government agencies or commercial partners, to expand the label into a product for virally induced ARDS. |

UPC
Twenty-four member states of the twenty-seven member EU states, with the exception of Poland, Spain and Croatia have acceded to the Agreement on a Unified Patent Court, or UPCA, which provides for a Unitary Patent, or UP, and led to the establishment of a Unified Patent Court, UPC. The UPCA has entered into force on June, 1 2023. Seventeen out of the twenty-four member states have fully ratified the UPCA when it entered into force and participate in the UPCA from the start. The remaining seven EU member states are expected to join within the next years. Since the start of the UPCA, a conventional European patent can be enforced centrally at the UPC but may also face central revocation proceedings in the UPC, unless it is opted-out of the jurisdiction of the new court system.
The UPC has exclusive competence in respect of civil litigation on matters relating to European patents, Unitary Patents, supplementary protection certificates issued for a product covered by such patents and European patent applications (for details see Article 32 of the UPCA). Therefore, the UPC is not only competent to hear cases concerning UPs but also cases concerning traditional European patent applications and patents (hereinafter “European patent(s)”), unless opted-out. The decision of the UPC in one country is binding in all other states participating in the UPCA. The decision, however, does not have any legally binding effect in EU member states not participating in the UPCA as well as in EPC contracting states which are not EU member states (e.g. Great Britain and Switzerland) and, therefore, are not eligible to participate in the new system.
It is generally expected that the UPC will be patent holder friendly both when it comes to assessment of validity of granted patents and infringement and that it may be beneficial for a patent holder to enforce and defend its patent at the UPC rather than at the EPO and/or national nullity court or civil court. Presently, however, there is no case law of the UPC that would allow a prediction of how the UPC may apply the patentability criteria when deciding on a central revocation action or a revocation counterclaim or how it will construe a claim in a central infringement proceeding. In view of these uncertainties, which are immanent to any new system on one hand, and the well-established practice of oppositions at the EPO as well as national invalidity and infringement proceedings on the other, we consider it a cautious and recommendable approach to opt-out all European patent applications and granted European patents from the UPC and to follow the case law of the UPC to determine the pros-and-cons of the UPC system. In case that the UPC appears to come to more favorable decision on validity and/or infringement than the EPO and national courts, it should be reconsidered to opt-in for one or more European patent or patent applications that have been previously opted out.

Our collaboration agreements
Co-development agreement with Staidson (Beijing) BioPharmaceuticals Co., Ltd. (as successor to Beijing Defengrei Biotechnology Co. Ltd (BDB))
In December 2015, we entered into a co-development agreement, or the Co-Development Agreement, with Beijing Defengrei Biotechnology Co. Ltd., or BDB, for the use of the vilobelimab manufacturing cell line in BDB’s development of drug candidates for sale in China. Pursuant to the agreement, we granted BDB an exclusive, non-transferable license to use the vilobelimab cell line and related intellectual property solely to develop and commercialize in China BDB’s drug candidates BDB-001 and BDB-002, as well as molecules that bind or interact with certain specified targets, or target-binding molecules.
Pursuant to the agreement, we are entitled to receive mid-single-digit percentage royalties on net sales of BDB’s products containing BDB-001 or BDB-002. We retain the right to develop and manufacture vilobelimab and IFX002 in China solely for the purpose of commercializing products outside of China and to use the vilobelimab cell line and IFX002 cell line in China for non-commercial purposes. To the extent that we are granted regulatory approval outside of China for commercialization of a product using vilobelimab or IFX002 for an indication, and BDB does not pursue regulatory approval for BDB-001 or BDB-002 in the same or a substantially similar indication in China, by providing written notice to BDB, we may elect to pursue regulatory approval to commercialize such products in the relevant indication in China. Should we exercise such right, we would be required to pay BDB mid-single-digit percentage royalties on our net sales of such products.
Pursuant to the Co-Development Agreement, BDB has the right to use the vilobelimab cell line to manufacture an anti-C5a antibody, namely BDB-001. BDB-001 may only be commercialized in China (PRC) by BDB, and InflaRx is not directly involved in the BDB-001 development, which remains the sole responsibility of BDB. Pursuant to the Co-Development Agreement, InflaRx owns all global commercial rights outside China to any and all discoveries derived from the development of BDB-001. To support BDB’s development of BDB-001, in 2020, InflaRx allowed BDB to conduct clinical studies with BDB-001 in Spain, India, Indonesia and Bangladesh. However, InflaRx remains the sole owner of all commercial rights to BDB-001 outside of China, including in countries in which BDB is conducting clinical trials. BDB has no rights to seek marketing authorization or to commercially exploit BDB-001 outside of China. Vilobelimab is not the product being tested in clinical trials by BDB in China. Rather, it is BDB’s own antibody called BDB-001.
In addition, we reserved the right to commercialize products containing BDB-001 and BDB-002 outside of China in indications for which we elect not to commercialize vilobelimab or IFX002. To the extent that we exercise this right, we would be required to pay BDB low single-digit percentage royalties on our net sales of such products.
BDB must notify us without undue delay of tests it conducts on target-binding molecules. If any such test results in binding or interaction with targets in a satisfactory manner to both BDB and us, BDB must notify us of such results and may, within a six-month period following such notice, exercise an option to commence commercializing the successfully tested target-binding molecules in China. To the extent that BDB exercises such option, BDB would be required to pay us low single-digit percentage royalties on net sales of products containing such target-binding molecules. BDB also grants us the right to exploit any target-binding molecules outside of China or, to the extent that BDB does not pursue regulatory approval in the same or a substantially similar indication, in China. To the extent that we exercise such rights, we would be required to pay BDB low to mid single-digit percentage royalties on our net sales of such products.
In November 2021, we entered into a second addendum to the Co-Development Agreement with BDB and Staidson (Beijing) BioPharmaceuticals Co., Ltd., or Staidson. Under the second addendum, BDB, being a wholly-owned affiliate of Staidson, assigned the Co-Development Agreement to Staidson together with all rights and obligations thereunder.
-79-
In December 2022, we amended our existing co-development agreement with Staidson to support Staidson in its regulatory approval efforts for its proprietary drug candidate BDB-001 for the treatment of COVID-19 in China. Pursuant to the amendment, we will receive increased royalties of 10% on net sales of BDB-001 for the treatment of COVID-19 in China. We granted Staidson an exclusive license for use in China to certain of our clinical, manufacturing and regulatory data regarding vilobelimab in order to support and facilitate the regulatory filing for BDB-001 for the treatment of severely ill COVID-19 patients with the Chinese National Medical Products Administration, or NMPA. Under the existing Co-Development Agreement, BDB-001 is being developed by Staidson for the treatment of severe COVID-19 and other inflammatory diseases in China. The agreement continues to be in force unless earlier terminated. The agreement may be terminated upon the mutual agreement of the parties, or by one party upon a breach by the other party that is not cured within 30 days after receiving notice of such breach. In addition, either party may terminate the agreement if the other party challenges the terminating party’s ownership of any intellectual property licensed to the non-terminating party under the agreement or undergoes certain bankruptcy or insolvency events.
Concomitantly to amending the Co-Development Agreement, we also entered into a share purchase agreement with Staidson Hong Kong Investment Company Limited, an affiliate of Staidson and a limited liability company organized under the law of Hong Kong, pursuant to which Staidson Hong Kong Investment Company Limited purchased ordinary shares from us for an aggregate amount of $2.5 million (€2.3 million) at a price of $5.00 per share, resulting in the sale of 500,000 shares. The share purchase agreement also includes an option pursuant to which Staidson Hong Kong Investment Company Limited may purchase additional ordinary shares, at our discretion, for an aggregate amount of an additional $7.5million. The option for such subsequent purchase will expire on the twelve-month anniversary of Staidson receiving regulatory approval for BDB-001 in China. Such subsequent investment would be made at the greater of $5.00 per share or at a 20% premium to the weighted average share price over the 15 trading days prior to the closing date of such subsequent investment.
Clinical trial collaboration and supply agreement with Merck & Co., Inc.
On March 20, 2020, we entered into a clinical trial collaboration and supply agreement with Merck & Co., Inc. (known as MSD outside the United States and Canada) to evaluate the combination of vilobelimab and Merck’s anti-PD-1 therapy, KEYTRUDA®1 (pembrolizumab) in patients with cSCC. Under the terms of the agreement, we conduct a Phase II clinical study with two vilobelimab arms, including one with pembrolizumab. In November 2023, we announced the development stop of vilobelimab in cSCC to prioritize other programs. Patients who are currently still in treatment will be treated for up to 24 months according to the protocol; however, no new patients will be enrolled in the study and clinical sites in which no patients are currently being treated will be closed down.
Sales and marketing
In June 2023, we began the commercialization of GOHIBIC (vilobelimab) in the United States for the treatment of COVID-19 in hospitalized adults when initiated within 48 hours of receiving IMV or ECMO. In connection with the start of the commercialization, we entered into agreements with certain subsidiaries of Cencora to act as the Group’s U.S. distributor and make GOHIBIC(vilobelimab) available for order by U.S. hospital customers under the EUA. Cencora provides cold storage, cold-chain distribution services, inventory management and secondary labeling/packaging, among other services.
To support our commercial efforts, we have hired and are continuing to hire U.S. experts with relevant experience in the commercialization of medical products in the hospital market, including in the areas of sales, sales operations, marketing, market access, distribution, medical affairs and others. In addition, we are expanding the necessary infrastructure, including IT systems, supply chain, financial reporting systems and inventory management systems both, internally and with the assistance of external service providers.
As we expand our commercial efforts, we continue to enhance our commercial strategic plan, further expanding our sales force and medical affairs teams, preparing relevant promotional and medical education materials to target healthcare providers and other stakeholders, refining our medical affairs strategy to increase awareness of the EUA among the medical community, and furthering our sales efforts.

In 2023, we recognized revenues in the amount of €63,089 from product sales for the first time since our inception. Revenues reported are sales to end customers (hospitals) in the United States.
During the twelve months ended December 31, 2023, the Group incurred €4.0 million of sales and marketing expenses. These expenses are mainly composed of €1.0 million in personnel costs and €1.9 million in external services for distribution of Gohibic. The Group started with its commercialization activities when the EUA was granted in April 2023. Prior to that, no sales and marketing expenses had been incurred.
We also intend to independently pursue the commercialization of vilobelimab for PG in the United States and Europe, if and when approved by the applicable regulators, by employing a targeted commercial infrastructure to promote access to vilobelimab through centers-of-excellence that treat PG in these core markets. We believe that such an organization will be able to address the community of physicians who are key specialists in treating the patient populations for which vilobelimab and any other product candidates are being developed. The responsibilities of the organization would include developing educational initiatives with respect to approved products and establishing relationships with key specialists in PG and any other relevant fields of medicine. The option to collaborate with a larger organization with an established commercial infrastructure will also be evaluated.
We might also consider pursuing the commercialization of vilobelimab in other indications or commercialization of our other development products independently. However, we are also considering potential partnerships with larger companies that have a more established infrastructure and greater financial resources in different areas, including in sales and marketing.
Manufacturing
We do not currently own or operate manufacturing facilities for the production of clinical or commercial quantities of our product candidates. We intend to rely on existing third-party contract manufacturers to produce our products and intend to recruit additional personnel with experience to manage the third-party contract manufacturers producing our product candidates and other product candidates or products that we may develop in the future. In addition, we engaged additional third-party manufacturers in Germany, the United States and other countries for activities related to potential sales, e.g. packaging and labeling of any of our approved products in the United States and elsewhere. We hold a manufacturing and importing license and participate in the drug product release procedure for vilobelimab by running a key immunological release assay in-house, allowing us to release only drug product batches that demonstrate the necessary, pre-specified high biological blocking activity. Thus, we are responsible for overseeing the entire manufacturing process and we release final fill-finished drug product with our qualified person.
Competition
The biopharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. While we believe that our technologies, knowledge, experience and scientific resources provide us with competitive advantages, we face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions and governmental agencies and public and private research institutions. Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future.
Competition in Pyoderma Gangrenosum
There are currently no drugs approved for the treatment of PG in major markets. The only locally approved treatment is adalimumab, which has been approved in Japan but in no other country on the basis of a small, locally conducted clinical trial. However, due to the high medical need associated with the disease, certain drugs are used in regular medical practice as treatment attempts for affected patients. These include certain orally administered drugs such as immunosuppressants, including cyclosporine or corticosteroids or antibiotics such as dapsone. In addition, topically applied tacrolimus is used in certain cases. Lastly intravenously administered TNF-alpha inhibitors such as infliximab or adalimumab or other biological drugs are also used, despite the fact that no formal regulatory approvals are in place.

As of the date hereof, to our knowledge, other treatments in active clinical trials include:
● | Orally administered baricitinib, a janus kinase-1 and janus kinase-2, or JAK1/JAK2, inhibitor is currently being investigated in a proof-of-concept, open label Phase II study |
● | Intravenously injected spesolimab, an interleukin-36 receptor, or IL-36R, monoclonal antibody is currently being investigated in a Phase II open label single-arm study |
● | Orally administered deucravacitinib, a janus kinase-2, or JAK2, inhibitor, is currently being investigated in a Phase I single arm with 10 patients |
● | Subcutaneously administered canakinumab, an anti-interleukin-1 beta, or IL-1 beta, monoclonal antibody in a 24 patients clinical Phase II trial of a subtype of PG, a pyogenic sterile arthritis pyoderma gangrenosum and acne (PAPA) syndrome |
Furthermore, the following developments have been terminated, completed or abandoned and have not advanced to registrational Phase III trials in recent years or failed in previous clinical trials:
● | Subcutaneously administered gevokizumab, an anti-interleukin-1 beta, or IL-1 beta, monoclonal antibody in three clinical Phase III trials enrolling 16, 15 and nine patients and in a Phase II study enrolling eight patients |
● | Intravenously administered bermekimab, an anti-interleukin-1 alpha, or IL-1 alpha, monoclonal antibody in a clinical Phase II study enrolling 10 patients |
● | Subcutaneously administered ixekizumab, an anti-interleukin-17 alpha, or IL-17 alpha, monoclonal antibody in a clinical Phase II trial after enrolling four patients |
● | Orally administered etrasimod, (APD334), a selective sphingosine-1-phosphate, or S1P-1, receptor modulator in a clinical Phase II trial enrolling two patients |
● | Subcutaneously administered ustekinumab, a monoclonal antibody targeting the shared p40 subunit of interleukin-12, or IL-12 and interleukin-23, or IL-23, described as being successfully treated in a patient on chronic immunosuppressive therapy in a single patient case-report study |
● | Subcutaneously administered secukinumab, an anti-interleukin-17 alpha, or IL-17 alpha, monoclonal antibody, described as being successfully treated after failure of other systemic therapies in a single patient case-report study |
If approved for the treatment of PG, vilobelimab would potentially face competition from currently used therapies, such as glucocorticoids, cyclosporin or other immunosuppressive therapies like adalimumab, infliximab or others.
