PART I

Item 1. BUSINESS

COMPANY OVERVIEW

LadRx Corporation (“LadRx” the “Company”, “we”, “us”, or “our”) is a biopharmaceutical research and development company specializing in oncology. The Company’s focus is on the discovery, research and clinical development of novel anti-cancer drug candidates that employ novel technologies that target chemotherapeutic drugs to solid tumors and reduce off-target toxicities. During 2017, LadRx’s discovery laboratory in Freiburg, Germany, synthesized and tested over 75 rationally designed drug conjugates with highly potent anti-cancer payloads, culminating in the creation of two distinct classes of compounds. Four lead candidates (LADR 7 through LADR-10) were selected based on in vitro and animal studies in several different cancer models, stability, and manufacturing feasibility. In addition, a novel companion diagnostic, ACDx™, was developed to identify patients with cancer who are most likely to benefit from treatment with these drug candidates.

On June 1, 2018, the Company launched Centurion BioPharma Corporation (“Centurion”), a wholly-owned private subsidiary, and transferred to Centurion all of its assets, liabilities and personnel associated with the laboratory operations in Freiburg, Germany. In connection with said transfer, the Company and Centurion entered into a Management Services Agreement whereby the Company agreed to render advisory, consulting, financial and administrative services to Centurion, for which Centurion shall reimburse the Company for the cost of such services plus a 5% service charge. On December 21, 2018, LadRx announced that Centurion had concluded the pre-clinical phase of development for its four LADR™ (Linker Activated Drug Release) drug candidates, and for its albumin companion diagnostic (ACDx™). As a result of completing this work, operations taking place at the pre-clinical laboratory in Freiburg, Germany were no longer needed and, accordingly, the lab was closed at the end of January 2019.

On March 9, 2022, Centurion merged with and into LadRx, with LadRx absorbing all of Centurion’s assets and continuing after the merger as the surviving entity (the “Merger”). The Merger was implemented through an agreement and plan of merger pursuant to Section 253 of the General Corporation Law of the State of Delaware (the “DGCL”) and did not require approval from either our or Centurion’s stockholders. The Certificate of Ownership merging Centurion into LadRx was filed with the Secretary of State of Delaware on March 9, 2022.

Effective September 26, 2022, we changed our name from CytRx Corporation to LadRx Corporation pursuant to a Certificate of Amendment to our Restated Certificate of Incorporation (the “Certificate of Incorporation”), as amended, filed with the Secretary of State of Delaware. In accordance with the DGCL, our board of directors (the “Board”) approved the name change and the Certificate of Amendment. Pursuant to Section 242(b)(1) of the DGCL, stockholder approval was not required for the name change or the Certificate of Amendment.

2023 Reverse Stock Split

The Company effected a 1-for-100 reverse stock split (the “Reverse Stock Split”) of its issued and outstanding shares of common stock on May 17, 2023, pursuant to which every 100 shares of the Company’s issued and outstanding shares of common stock were converted into one share of common stock without any change in the par value per share. Any fraction of a share of common stock that would otherwise have resulted from the Reverse Stock Split were rounded up to the nearest whole share. All share and per share amounts in this Annual Report have been adjusted to reflect the reverse stock split as if it had occurred at the beginning of the earliest period presented.

Corporate Information

We are a Delaware corporation, incorporated in 1985. Our corporate offices are located at 11726 San Vicente Boulevard, Suite 650, Los Angeles, California 90049, and our telephone number is (310) 826-5648. Our web site is located at http://www.ladrxcorp.com. We do not incorporate by reference into this Annual Report the information on, or accessible through, our website, and you should not consider it as part of this Annual Report.

LADR Drug Discovery Platform

The LADR™ Technology offers the opportunity for multiple pipeline drugs. The Company’s LADR™ technology platform consists of an organic backbone that is attached to a chemotoxic agent. The purpose of the LADR™ backbone is to first target and deliver the chemotoxic agent to the tumor environment, and then to release the chemotoxic agent within the tumor. By delivering, concentrating, and releasing the chemotoxic agent within the tumor, one expects to reduce the off-target side-effects of the chemotherapeutic, which in turn allows for several-fold higher dosing of the chemotherapeutic to the patient. Being small organic molecules, the Company expects LADR-based drugs to offer the benefits of targeting the tumor without the complexity, side effects, and expense inherent in macromolecules such as antibodies and nanoparticles.

The Company’s LADR-based drugs use circulating albumin as the binding target and as the trojan horse to deliver the LADR™ drugs to the tumor. Albumin is the most abundant protein in plasma and accumulates inside tumors due to the aberrant vascular structure that exists within solid tumors. Tumors use albumin as a nutritional source and for transport of signaling and other molecules that are important to the maintenance and growth of the tumor, which makes albumin an excellent target for drugs that are intended for solid tumors.

The Company’s LADR™ development efforts are focused on two classes of ultra-high potency albumin-binding drugs. These LADR-based drugs, LADRs 7, 8, 9, and 10, combine the proprietary LADR™ backbone with novel derivatives of the auristatin and maytansinoid drug classes. Auristatin and maytansinoid are highly potent chemotoxins, and require targeting to the tumor for safe administration to humans, as is the case for the U.S. Food and Drug Administration (“FDA”)-approved drugs Adcetris (auristatin antibody-drug-conjugate manufactured by Seagen, Inc.) and Kadcyla (maytansine antibody-drug-conjugate manufactured by Genentech, Inc.). We believe that LADR-based drugs offer the benefits of tumor targeting without the disadvantages of antibodies and other macromolecules, which include expense, complexity, and negative side effects. Additionally, albumin is a very well-characterized drug target, which we believe will reduce clinical and regulatory costs and risks.

The Company’s postulated mechanism of action for LADR-based drugs is as follows:

The first-generation LADR-based drug is called Aldoxorubicin. Aldoxorubicin is the well-known drug doxorubicin attached to the first generation LADR™ backbone (LADRs 7-10 employ a next generation LADR™ backbone). Aldoxorubicin has been administered to over 600 human subjects in human clinical trials and has proven the concept of LADR™ in that several-fold more doxorubicin can be safely administered to patients when the doxorubicin is attached to LADR™ than when administered as native doxorubicin. Aldoxorubicin has been licensed to ImmunityBio and is currently in a Phase II trial for pancreatic cancer.

The next generation LADR™ drugs are termed LADR 7, 8, 9, and 10. A great deal of Investigational New Drug (“IND”) enabling work has already been accomplished on LADR 7-10, including in-silico modeling, in-vitro efficacy testing in several different cancer models, in-vivo dosing, safety, and efficacy testing in several different cancer models in animals. We have also developed and proven manufacturability, an important step prior to beginning human clinical trials.

The IND-enabling work that remains prior to applying to the FDA for first-in-human studies for LADR 7-10 is limited due to the extensive experimentation already completed. For example, in the case of LADR 7, a manufacturing run under Good Manufacturing Practices (GMP) has been completed and the GMP LADR 7 currently in hand is sufficient to carry out final toxicology studies, and to initiate Phase IA studies in human subjects.

The final toxicology studies required for the IND for LADR 7 are underway and we expect the toxicology studies to be completed and the IND application for LADR 7 to be filed with the FDA by the end of the third quarter of 2024 or the beginning of the fourth quarter of 2024. Absent a clinical hold from the FDA, this timeline should allow the Company to be ready for first-patient dosing with LADR 7 by the end of 2024 (the period for the FDA review of an IND application is 30 days). If the Company encounters difficulties with the toxicology program or fails to meet the FDA’s requirements for the IND application, the first-patient dosing could be substantially delayed.

Because the LADR™ backbone in future products would be the same as the LADR™ backbone in current product candidates, (i.e. the chemotoxin can be changed without changing the LADR™ backbone), management anticipates that future product candidates beyond LADR 7-10 may enjoy abbreviated pre-clinical pathways to first-in-human. Such abbreviated pathways would be subject to FDA review and agreement.

The Company’s novel companion diagnostic, ACDx™ (albumin companion diagnostic) was developed to identify patients with cancer who are most likely to benefit from treatment with the four LADR™ lead assets. We have not yet determined whether the use of a companion diagnostic will be necessary or helpful, and plan to continue to investigate this question in parallel to the pre-clinical and clinical development of LADRs 7-10.

The LADR™ backbone and drugs that employ LADR™ are protected by domestic and international patents, and additional patents are pending.

Business Strategy for LADR™ Platform

With the non-dilutive financing concluded with XOMA (as defined below) in June 2023, the Company is now focused on completing the work necessary to file an IND application with the FDA for LADR7. For example, the Company recently completed the production of approximately 100 grams of LADR7 under GMP, which is sufficient to carry out final toxicology studies, and to initiate Phase IA studies in human subjects.

The Company has also initiated the Good Laboratory Practices (“GLP”) toxicology program that is expected to form the foundation of the IND application for LADR 7 to the FDA. Management expects the toxicology studies to be completed and the IND application for LADR 7 to be filed with the FDA by the end of the third quarter of 2024 or the beginning of the fourth quarter of 2024. Absent a clinical hold from the FDA, this timeline should allow the Company to be ready for first-patient dosing with LADR 7 by the end of 2024 (the period for the FDA review of an IND application is 30 days). If the Company encounters difficulties with the toxicology program or fails to meet the FDA’s requirements for the IND, the first-patient dosing could be substantially delayed.

Management will continue to explore in parallel both partnered and non-partnered funding and development strategies for LADR™ with a goal of obtaining the least costly capital possible to enable value inflection milestones.

Partnering of Aldoxorubicin

On July 27, 2017, the Company entered into an exclusive worldwide license with ImmunityBio, Inc. (the “2017 License Agreement”) (formerly known as NantCell, Inc., and which merged with NantKwest Inc. in March 2021 (“ImmunityBio”)), granting to ImmunityBio the exclusive rights to develop, manufacture and commercialize aldoxorubicin in all indications. As a result, we are no longer directly working on the development of aldoxorubicin. As part of the 2017 License Agreement, ImmunityBio made a strategic investment of $13 million in LadRx’s common stock at $660.00 per share (adjusted to reflect our reverse stock splits), a premium of 92% to the market price on that date. The Company also issued a warrant to ImmunityBio to purchase up to 5,000 shares of common stock at $660.00 per share, which such warrant expired on January 26, 2019.

ImmunityBio is conducting an open-label, randomized, Phase 2 study of a combination of immunotherapy, aldoxorubicin, and standard-of-care chemotherapy versus standard-of-care chemotherapy alone for the treatment of locally advanced or metastatic pancreatic cancer in patients who have had 1 or 2 lines of treatment (Cohorts A and B) or 3 or greater lines of treatment (cohort C). In June 2022, Immunity Bio presented data at the American Society of Clinical Oncology meeting showing that patients receiving combination immunotherapy with aldoxorubicin plus standard-of-care chemotherapy experienced overall survival of 5.8 months, compared to 3 months for historical control patients that had received only the standard-of-care chemotherapy (n=78, 95% confidence interval of 4 to 6.9 months). An additional 25 patients in the experimental group remain in the study. As of the date of this Annual Report, there have been no treatment-related deaths, and serious adverse events have been uncommon (6%).

Aldoxorubicin has received Orphan Drug Designation (“ODD”) by the FDA for the treatment of soft tissue sarcoma (“STS”). ODD provides several benefits including seven years of market exclusivity after approval, certain R&D related tax credits, and protocol assistance by the FDA. European regulators granted aldoxorubicin Orphan designation for STS which confers ten years of market exclusivity among other benefits.

Royalty Purchase Agreement with XOMA

On June 21, 2023, the Company, entered into (i) a Royalty Purchase Agreement (the “Royalty Agreement”) with XOMA (US) LLC (“XOMA”), for the sale, transfer, assignment and conveyance of the Company’s right, title and interest in and to certain royalty payments and milestone payments with respect to aldoxorubicin, and (ii) an Assignment and Assumption Agreement (the “Assignment Agreement”) with XOMA for the sale, transfer, assignment and conveyance of the Company’s right, title and interest in the Asset Purchase Agreement (the “2011 Arimoclomol Agreement”) between the Company and Orphazyme ApS (“Orphazyme”), dated as of May 13, 2011, and assigned to Zevra Denmark A/S (“Zevra Denmark”), effective as of June 1, 2022, which includes certain royalty and milestone payments with respect to arimoclomol. The combined aggregate purchase price paid to the Company for the sale, transfer, assignment and conveyance of the Company’s right, title and interest in and to aldoxorubicin and arimoclomol was $5 million, less certain transaction fees and expenses.

The Royalty Agreement and the Assignment Agreement also provide for up to an additional $6 million based on regulatory and commercial milestones related to the development of arimoclomol and aldoxorubicin by their respective sponsors, Zevra, Inc. and Immunity Bio. The $6 million in potential post-closing payments is comprised of $1 million upon acceptance by the FDA of the arimoclomol New Drug Application (“NDA”), $1 million upon first commercial sale of arimoclomol, and $4 million upon FDA approval of aldoxorubicin. All royalty and milestone payments made to XOMA will be net of the existing licensing and milestone obligations owed by LadRx related to arimoclomol and aldoxorubicin.

Pursuant to the Royalty Agreement, the Company agreed to sell, transfer, assign and convey to XOMA, among other payments, all royalty payments and regulatory and commercial milestone payments payable to the Company pursuant to the worldwide license agreement, dated July 27, 2017, by and between the Company and Immunity Bio. The Royalty Agreement also provides for the sharing of certain rights with XOMA to bring any action, demand, proceeding or claim as related to receiving such payments.

Management determined that the Royalty Agreement is not considered to be with a customer, and it does not fall within the scope of ASC 606. Instead, the Royalty Agreement represents an in-substance sale of nonfinancial assets, and, therefore, should be accounted for within the scope of ASC 610-20. As such, the Company recognized such net proceeds as other income in the accompanying statement of operations.

Transfer of Rights to Molecular Chaperone Assets (Orphayzme)

On May 13, 2011, pursuant to the Asset Purchase Agreement by and between the Company and Orphazyme A/S (“Orphazyme”, formerly Orphazyme ApS), LadRx sold the rights to arimoclomol and iroxanadine, based on molecular chaperone regulation technology, in exchange for a one-time, upfront payment and the right to receive up to a total of $120 million in milestone payments upon the achievement of certain pre-specified regulatory and business milestones, as well as royalty payments based on a specified percentage of any net sales of products derived from arimoclomol (the “2011 Arimoclomol Agreement”). Orphazyme transferred its rights and obligations under the 2011 Arimoclomol Agreement to KemPharm Denmark A/S (“KemPharm”), a wholly owned subsidiary of KemPharm Inc., in May 2022.

In May 2021, Orphazyme announced that the pivotal phase 3 clinical trial for arimoclomol in Amyotrophic Lateral Sclerosis did not meet its primary and secondary endpoints, reducing the maximum amount that LadRx currently has the right to receive under the 2011 Arimoclomol Agreement to approximately $100 million. Orphazyme also tested arimoclomol in Niemann-Pick disease Type C (“NPC”) and Gaucher disease, and following a Phase II/III trial submitted to the FDA a NDA for the treatment of NPC with arimoclomol. On June 18, 2021, Orphazyme announced it had received a complete response letter (the “Complete Response Letter”) from the FDA indicating the need for additional data. In late October 2021, Orphazyme announced it held a Type A meeting with the FDA, at which the FDA recommended that Orphazyme submit additional data, information and analyses to address certain topics in the Complete Response Letter and engage in further interactions with the FDA to identify a pathway to resubmission. The FDA concurred with Orphazyme’s proposal to remove the cognition domain from the NPC Clinical Severity Scale (“NPCCSS”) endpoint, with the result that the primary endpoint is permitted to be recalculated using the 4- domain NPCCSS, subject to the submission of additional requested information which Orphazyme had publicly indicated that it intended to provide. To bolster the confirmatory evidence already submitted, the FDA affirmed that it would require additional in vivo or pharmacodynamic (PD)/pharmacokinetic (PK) data.

Orphazyme had also submitted a Marketing Authorization Application (“MAA”) with the European Medicines Agency (the “EMA”). In February 2022, Orphazyme announced that although they had received positive feedback from the Committee for Medicinal Products for Human Use (“CHMP”) of the EMA, they were notified by the CHMP of a negative trend vote on the MAA for arimoclomol for NPC following an oral explanation.

On May 31, 2022, Orphazyme announced that it had completed the sale of substantially all of its assets and business activities for cash consideration of $12.8 million and assumption of liabilities estimated to equal approximately $5.2 million to KemPharm (the “KemPharm Transaction”). KemPharm is a specialty biopharmaceutical company focused on the discovery and development of novel treatments for rare CNS diseases. As part of the KemPharm Transaction, all of Orphazyme’s obligations to LadRx under the 2011 Arimoclomol Agreement, including with regard to milestone payments and royalties on sales, were assumed by KemPharm. KemPharm is expected to continue the early access programs with arimoclomol, and to continue to pursue the potential approval of arimoclomol as a treatment option for NPC. KemPharm resubmitted the NDA for arimoclomol in 2023. It is also identifying a regulatory path forward with the EMA. KemPharm re-branded to Zevra Therapeutics, Inc. in February 2023.

Assignment and Assumption Agreement with XOMA

On June 21, 2023, the Company entered into the Assignment Agreement with XOMA, pursuant to which, among others, the Company agreed to sell, transfer and assign to XOMA the Company’s right, title and interest in the arimoclomol pursuant to the 2011 Arimoclomol Agreement, including the right to receive certain milestone, royalty and other payments from Zevra.

Pursuant to the Assignment Agreement, the Company is entitled to receive (i) a one-time payment of $1 million upon acceptance of a re-submission of a NDA to the FDA for arimoclomol, and (ii) a one-time payment of $1 million upon the first invoiced sale in certain territories of a pharmaceutical product derived from arimoclomol as an active pharmaceutical ingredient, subject to the receipt of the applicable regulatory approval required to sell such a product in such countries. In January 2024, Zevra announced the FDA had accepted the NDA for arimoclomol and the Company received the one-time payment of $1 million in February 2024.

Commercialization and Marketing

We currently have no sales, marketing or commercial product distribution capabilities or experience in marketing products.

We are searching for a development and commercialization partner or a financing for our LADR drug candidates and do not currently plan on commercializing them ourselves. Over the past two years, we have been unable to attract either a development and commercial partner or a financing for this endeavor; however, we are continuing to pursue all possibilities.

Patents and Proprietary Technology

We actively seek patent protection for our technologies, processes, uses, and ongoing improvements and consider our patents and other intellectual property to be critical to our business. We regularly evaluate the patentability of new inventions and improvements developed by us or our collaborators, and, whenever appropriate, will endeavor to file U.S. and international patent applications to protect these new inventions and improvements. We cannot be certain that any of the current pending patent applications we have filed or licensed, or any new patent applications we may file or license, will ever be issued in the U.S. or any other country. There also is no assurance that any issued patents will be effective to prevent others from using our products or processes. It is also possible that any patents issued to us, as well as those we have licensed or may license in the future, may be held invalid or unenforceable by a court, or third parties could obtain patents that we would need to either license or to design around, which we may be unable to do. Current and future competitors may have licensed or filed patent applications or received patents and may acquire additional patents and proprietary rights relating to compounds, products or processes that may be competitive with ours.

In addition to patent protection, we attempt to protect our proprietary products, processes and other information by relying on trade secrets and non-disclosure agreements with our employees, consultants and certain other persons who have access to such products, processes and information. Under the agreements, all inventions conceived by employees are our exclusive property, but there is no assurance that these agreements will afford significant protection against misappropriation or unauthorized disclosure of our trade secrets and confidential information.

As of January 31, 2024, we have three granted U.S. patents and fifty granted foreign patents, and two pending U.S. patent applications and twenty-four pending foreign patent applications covering our LADR^TM-related technology including LADR 7, LADR-8, LADR-9 and LADR-10. The un-extended patent term of patents that issue covering our LADR^TM-related technology is between June 2036 and November 2038. We also have one granted foreign patent, one pending US patent application, and thirteen pending foreign patent applications covering our albumin companion diagnostic (ACDx^TM). The un-extended patent term of patents that issue covering our ACDx^TM is July 2039. The patents and patent applications covering our LADR^TM-related technology, and ACDx^TM are assigned to LadRx. In conjunction with the 2017 License Agreement, we granted ImmunityBio an exclusive license to all our aldoxorubicin-related patents, including the rights in three granted U.S. patents, twenty-one granted foreign patents and six pending foreign patent applications covering aldoxorubicin and related technologies. Our intellectual property holdings relating to aldoxorubicin, and related technologies include an exclusive license from Vergell Medical, S.A. or Vergell. Patents and applications that cover pharmaceutical compositions comprising aldoxorubicin and their use in treating cancer (including glioblastoma) have un-extended patent terms expiring between December 2033 and June 2034.

LICENSE AGREEMENTS

Molecular Chaperone Assets

The agreement relating to our worldwide rights to arimoclomol provides for our payment up to an aggregate of $3.65 million upon receipt of milestone payments from Zevra ( formerly KemPharm).

Competition

The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. While we believe that our LADR™ technology platform and ultra-high potency albumin-bind drug conjugates 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 drug candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future.

Many competitors and potential competitors have substantially greater scientific, research and product development capabilities, as well as greater financial, marketing and human resources than we do. In addition, many specialized biotechnology firms have formed collaborations with large, established companies to support the research, development and commercialization of products that may be competitive with ours.

There are many companies developing antibody-drug conjugates (ADC) for the treatment of cancer and some that use the same classes of cytotoxic payloads as we are currently using. These include Takeda Pharmaceutical Co. Ltd. and Seattle Genetics Inc. who market Adcetris®, and F. Hoffmann-LaRoche Ltd./Genentech who market Kadcyla®. According to www.clinicaltrials.gov, many other major pharmaceutical companies, including Celgene Corp. and GlaxoSmithKline are testing an ADC in either on-going or currently enrolling clinical trials. Other companies have created or have programs to create cell-killing agents for attachment to antibodies or other targeting agents. These companies may compete with us for technology out-license arrangements.

In addition to ADCs, we face competition from other nanomedicine platforms developing targeted therapies, including platforms focused on nanoparticles and liposomes. Non-ADC therapies may be in development for the cancer types we or our partners elect to pursue. Further, these companies may also compete with us for technology out-license arrangements.

Continuing development of conventional and targeted cytotoxins by large pharmaceutical companies and biotechnology companies may result in new compounds that may compete with our product candidates. More recently, immuno-oncology therapies that stimulate the body’s own defense system to attack cancers are being developed by certain of these companies and some have been approved for use as cancer therapeutics. In the future, immuno-oncology agents including cell therapies, targeted therapies or cytotoxic treatments may compete with our product candidates. Other companies have created or have programs to create potent cell-killing agents for attachment to tumor targeting agents. These companies may compete with us for technology out-license arrangements.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we obtain approval for ours. In addition, our ability to compete may be affected in many cases by insurers or other third-party payors seeking to encourage the use of generic products. If our drug candidates achieve marketing approval, we expect that they will be priced at a significant premium over competitive generic products.

Many companies, including large pharmaceutical and biotechnology firms with financial resources, research and development staffs, and facilities that may be substantially greater than those of ours or our strategic partners or licensees, are engaged in the research and development of pharmaceutical products that could compete with our potential products. To the extent that we seek to acquire, through license or otherwise, existing or potential new products, we will be competing with numerous other companies, many of which will have substantially greater financial resources, large acquisition and research and development staffs that may give those companies a competitive advantage over us in identifying and evaluating these drug acquisition opportunities. Any products that we acquire will be competing with products marketed by companies that in many cases will have substantially greater marketing resources than we have. The industry is characterized by rapid technological advances and competitors may develop their products more rapidly and such products may be more effective than those currently under development or that may be developed in the future by our strategic partners or licensees. Competitive products for a number of the disease indications that we have targeted are currently being marketed by other parties, and additional competitive products are under development and may also include products currently under development that we are not aware of or products that may be developed in the future.

Government Regulation

Regulation of Pharmaceuticals in the United States

The U.S. and other developed countries extensively regulate the preclinical and clinical testing, manufacturing, labeling, storage, record-keeping, advertising, promotion, export, marketing and distribution of drugs and biologic products. In the United States, the FDA, under the Federal Food, Drug, and Cosmetic Act (“FDCA”), the Public Health Service (“PHS”) Act and other federal statutes and regulations, regulates pharmaceutical and biologic products and product candidates, and the parties engaged in the development, testing, manufacture, distribution, storage, marketing, labeling, advertising, and/or commercialization thereof (in addition to any other related activities) are subject to rigorous pre- and post-market requirements.

To obtain FDA approval for a new drug candidate, we must, among other requirements, submit data supporting the candidate’s safety and efficacy for the intended indication(s), as well as detailed information on the manufacture and composition of the product candidate. In most cases, this will require extensive laboratory tests and preclinical and clinical trials. The collection of these data, as well as the preparation of applications for review by the FDA involve significant time and expense and are inherently complex and uncertain. The FDA may not act quickly or favorably in reviewing these applications, and we (and/or any current or future partners in development) may encounter significant difficulties or costs in our (and/or their) efforts to obtain FDA approvals that could delay or preclude the U.S. commercialization of one or more of our product candidates.

The process required by the FDA before a new drug may be marketed in the U.S. generally involves some or all of the following key steps:

Preclinical Studies

After a therapeutic candidate is identified for development, it enters the preclinical or nonclinical testing stage. Preclinical studies include laboratory evaluation of product chemistry, toxicity and formulation, as well as animal studies to assess potential safety and efficacy. Preclinical tests intended for submission to the FDA to support the safety of a product candidate must be conducted in compliance with GLP regulations and the United States Department of Agriculture’s Animal Welfare Act, if applicable. A drug sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data and any available clinical data or literature, among other things, to the FDA as part of an IND. Some nonclinical testing may continue after the IND is submitted. In addition to including the results of the nonclinical studies, the IND will include one or more clinical protocols detailing, among other things, the objectives of the clinical trial and the safety and effectiveness criteria to be evaluated.

An IND automatically becomes effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions related to one or more proposed clinical trials and places the clinical trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. As a result, submission of an IND may not result in the FDA allowing clinical trials to commence. A clinical hold may occur at any time during the life of an IND and may affect one or more specific studies or all studies conducted under the IND. Occasionally, clinical holds are imposed due to manufacturing issues that may present safety issues for the clinical study subjects.

Human Clinical Trials in Support of an NDA

The clinical investigation of an investigational new drug is divided into three phases that typically are conducted sequentially but may overlap or be combined. The three phases are as follows:

A clinical trial may combine the elements of more than one phase and the FDA often requires more than one Phase 3 trial to support marketing approval of a product candidate. A company’s designation of a clinical trial as being of a particular phase is not necessarily indicative that the study will be sufficient to satisfy the FDA requirements of that phase because this determination cannot be made until the protocol and data have been submitted to and reviewed by the FDA. Human clinical trials are inherently uncertain and Phase 1, Phase 2 and Phase 3 testing may not be successfully completed.

A pivotal trial is a clinical trial that is believed to satisfy FDA requirements for the evaluation of a product candidate’s safety and efficacy such that it can be used, alone or with other pivotal or non-pivotal trials, to support regulatory approval. Generally, pivotal trials are Phase 3 trials, but they may be Phase 2 trials if the design provides a well-controlled and reliable assessment of clinical benefit, particularly in an area of unmet medical need.

Clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with the FDA’s GCP requirements. They must be conducted under protocols detailing the objectives of the trial, dosing procedures, research subject selection and exclusion criteria and the safety and effectiveness criteria to be evaluated. Each protocol, and any subsequent material amendment to the protocol, must be submitted to the FDA as part of the IND, and progress reports detailing the status of the clinical trials must be submitted to the FDA annually. Sponsors also must report to the FDA serious and unexpected adverse reactions in a timely manner, any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigation brochure or any findings from other studies or animal or in vitro testing that suggest a significant risk in humans exposed to the product or therapeutic candidate. The FDA may order the temporary or permanent discontinuation of a clinical trial at any time, via a clinical hold, or impose other sanctions if it believes that the clinical trial is not being conducted in accordance with FDA requirements or that the subjects are being exposed to an unacceptable health risk. An institutional review board (“IRB”), is responsible for ensuring that human subjects in clinical studies are protected from inappropriate study risks. An IRB at each institution participating in the clinical trial must review and approve the protocol before a clinical trial commences at that institution and must also approve the information regarding the trial and the consent form that must be provided to each research subject or the subject’s legal representative, monitor the trial until completed and otherwise comply with IRB regulations. The IRB also may halt a study, either temporarily or permanently, for failure to comply with GCP or the IRB’s requirements, or if the investigational new drug has been associated with unexpected serious harm to patients.

During the development of a new drug product candidate, sponsors are given opportunities to meet with the FDA at certain points; specifically, prior to the submission of an IND, at the end of Phase 2 and before an NDA is submitted. Meetings at other times may be requested. These meetings can provide an opportunity for the sponsor to share information about the data gathered to date and for the FDA to provide advice on the next phase of development. Sponsors typically use the meeting at the end of Phase 2 to discuss their Phase 2 clinical results and present their plans for the pivotal Phase 3 clinical trial that they believe will support the approval of the new therapeutic.

Post-approval trials, sometimes referred to as “Phase 4” clinical trials, may be conducted after initial marketing approval. These trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, FDA may mandate the performance of “Phase 4” clinical trials.

Concurrent with clinical trials, sponsors usually complete additional animal safety studies, develop additional information about the chemistry and physical characteristics of the product candidate and finalize a process for manufacturing commercial quantities of the product candidate in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other criteria, the sponsor must develop methods for testing the identity, strength, quality, and purity of the finished drug product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

Marketing Application Submission and FDA Review

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, detailed information on the product candidate is submitted to the FDA in the form of an NDA requesting approval to market the drug for one or more indications. An NDA includes all relevant data available from pertinent nonclinical studies and clinical trials, including negative or ambiguous results as well as positive findings, together with detailed information on the product candidate’s chemistry, manufacturing, and controls, or CMC, and proposed labeling, among other things. To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and efficacy of the product candidate for its intended use to the satisfaction of the FDA.

Under the Prescription Drug User Fee Act (“PDUFA”), each NDA must be accompanied by a significant user fee. The FDA adjusts the PDUFA user fees on an annual basis. PDUFA also imposes an annual program fee for prescription drug products. Fee waivers or reductions are available in certain circumstances, such as where a waiver is necessary to protect the public health, where the fee would present a significant barrier to innovation, or where the applicant is a small business submitting its first human therapeutic application for review.

Under the goals and policies agreed to by the FDA under PDUFA, the FDA has ten months from receipt in which to complete its initial review of a standard NDA for a drug that is not a new molecular entity, and six months from the receipt date for an application with priority review. The FDA does not always meet its PDUFA goal dates, and the review process is often significantly extended by FDA requests for additional information or clarification and a sponsor’s process to respond to such inquiries. As a result, the NDA review process can be very lengthy. Most innovative drug products (other than biological products) obtain FDA marketing approval pursuant to an NDA submitted under Section 505(b)(1) of the FDCA, commonly referred to as a traditional (or full) NDA.

The FDA conducts a preliminary review of all NDAs it receives to ensure that they are sufficiently complete for substantive review before it accepts them for filing. The FDA may refuse to file any NDA that it deems incomplete or not properly reviewable at the time of submission, and may request additional information rather than accept an NDA for filing. In this event, the application must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing. The FDA has 60 days after submission of an NDA to conduct an initial review to determine whether it is sufficient to accept for filing. If the submission is accepted for filing, the FDA begins an in-depth substantive review of the NDA. The FDA reviews the NDA to determine, among other things, whether the proposed product is safe and effective for its intended use, whether it has an acceptable purity profile and whether the product is being manufactured in accordance with cGMPs. During its review of an NDA, the FDA may refer the application to an advisory committee of independent experts for a recommendation as to whether the application should be approved. An advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendation of an advisory committee, but it typically follows such recommendations. Data from clinical trials are not always conclusive, and the FDA or its advisory committee may interpret data differently than the NDA sponsor interprets the same data. The FDA may also re-analyze the clinical trial data, which could result in extensive discussions between the FDA and the applicant during the review process.

Before approving an NDA, the FDA will typically inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving the NDA, the FDA will typically inspect one or more clinical sites to assure that the clinical trials were conducted in compliance with IND trial requirements and GCP requirements and to assure the integrity of the clinical data submitted to the FDA. To ensure cGMP and GCP compliance by its employees and third-party contractors, an applicant must incur significant expenditure of time, money and effort in the areas of training, record keeping, production and quality control.

The FDA may also require the submission of a risk evaluation and mitigation strategy, or “REMS,” if it determines that a REMS is necessary to ensure that the benefits of the drug outweigh its risks and to assure the safe use of the product. A REMS could include medication guides, physician communication plans, assessment plans and/or elements to assure safe use, such as restricted distribution methods, patient registries or other risk minimization tools. The FDA determines the requirement for a REMS, as well as the specific REMS provisions, on a case-by-case basis. If the FDA concludes a REMS is needed, the sponsor must include a proposed REMS within its NDA submission.

After evaluating the NDA and all related information, including the advisory committee recommendation, if any, and inspection reports regarding the manufacturing facilities where the drug product or its API will be produced and the clinical trial sites, the FDA will either issue an approval letter or, in some cases, a complete response letter (“CRL”) that describes all of the specific deficiencies that the FDA has identified in the NDA. A CRL indicates that the review cycle of the application is complete but that the application will not be approved in its present form. The deficiencies identified may be minor (e.g., requiring labeling changes) or major (e.g., requiring additional clinical trials and/or other time-consuming and expensive measures to generate the requisite safety and/or efficacy data). After receiving a CRL, an applicant may either resubmit the NDA, addressing all of the deficiencies identified in the letter or withdraw the application. FDA will issue a letter within 30 days of an NDA resubmission acknowledging receipt and informing the applicant as follows. For resubmissions deemed to be complete responses to all deficiencies identified in the CRL, such letter will contain FDA’s designation of the resubmission as Class 1 or Class 2 (based on the nature of information received therein) and the corresponding due date by which it will take action (2 months for Class 1 resubmissions and 6 months for Class 2). If FDA does not find the resubmission to be a complete response to all CRL deficiencies, the FDA will inform the applicant, and the FDA’s “review clock” will not start until a complete response is received.

Even if a drug product receives NDA approval, the approval may be significantly limited to specific indications and dosages and/or subject to limitations, specific labeling requirements, and/or other conditions that must be met to lawfully market the product in the United States, any or all of which could restrict the commercial value of the product. For example, the FDA may require that certain contraindications, warnings, and/or precautions be included in the product’s labeling. The FDA may also impose restrictions and conditions on product distribution, prescribing, or dispensing in the form of a REMS, or otherwise limit the scope of any approval. In addition, the FDA may require post marketing clinical trials, sometimes referred to as “Phase 4” clinical trials, designed to further assess a product’s safety and effectiveness, and/or testing and surveillance programs to monitor the safety of approved products that have been commercialized.

Post-Approval Requirements for Prescription Drugs

Following approval of a new drug product, the manufacturer and the approved drug are subject to pervasive and continuing regulation by the FDA, including, among other things, monitoring and recordkeeping activities, reporting of adverse experiences with the product, product sampling and distribution restrictions, and promotion and advertising requirements.

Promotional communications must be carefully crafted to ensure compliance with all applicable FDA regulations pertaining to prescription-drug marketing and labeling. In particular, prescription-drug advertisements must generally (1) not be false or misleading, (2) present a “fair balance” of information describing both the risks and benefits associated with the drug, (3) include facts that are “material” to the product’s advertised uses, and (4) include a “brief summary” that mentions every risk described in the product’s labeling. Further, where the intended use of a prescription drug differs from the intended use approved by FDA, as listed in the product’s approved NDA, FDA has asserted that the product is an unapproved “new drug” and taken enforcement action against sponsors for introducing such unapproved new drugs into interstate commerce in violation of the FDCA. This prohibited practice is also called “off-label” promotion. Although physicians may prescribe legally available products for off-label uses, sponsors may not legally market or promote such uses. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability.

To market an approved drug product for a new indication (i.e., beyond and/or differing from that set forth in the approved NDA), the sponsor must submit a new NDA (or NDA supplement), which, in many cases, will require the completion of adequate and well-controlled clinical trials to demonstrate the product’s safety and efficacy in the new indication. There is no guarantee that FDA will approve an NDA seeking an expansion of an approved drug’s labeling and/or indications for use more quickly than an NDA involving a novel product (i.e., that has never been approved for any indication) or ever. Relatedly, if the sponsor (or a contractor, partner, or other affiliated party) makes any post-market modifications to an approved drug or the production thereof, including changes in labeling or manufacturing processes or facilities, among other things, it may be required to submit and obtain FDA approval of a new NDA or an NDA supplement.

In addition, FDA regulations require that products be manufactured in specific approved facilities and in accordance with cGMPs. The cGMP regulations include requirements relating to organization of personnel, buildings and facilities, equipment, control of components and drug product containers and closures, production and process controls, packaging and labeling controls, holding and distribution, laboratory controls, records and reports and returned or salvaged products. Drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and some state agencies, and are subject to periodic unannounced inspections by the FDA for compliance with cGMPs and other requirements. Changes to the manufacturing process, specifications or container closure system for an approved drug product are strictly regulated and often require prior FDA approval before being implemented. FDA regulations also require, among other things, the investigation and correction of any deviations from cGMPs and the imposition of reporting and documentation requirements upon the NDA sponsor and any third-party manufacturers involved in producing the approved drug product. Accordingly, both sponsors and manufacturers must continue to expend time, money, and effort on systems relating to production and quality control to maintain cGMP compliance and other aspects of quality control and quality assurance, and to ensure ongoing compliance with other statutory requirements of the FDCA. We anticipate that the products we may commercialize in the United States (if any) will be manufactured by our strategic partners (including licensees) or contractors (including any third parties who may be engaged by us or one of our partners to conduct any commercialization activities, as well as downstream subcontractors, as applicable) and we may, thus, be subject to enforcement action for any such third parties’ failures to comply with the applicable post-market regulations or otherwise be adversely affected by any of our partners’ or contractors’ compliance issues.

The FDA may withdraw its approval for a drug product if compliance with regulatory requirements is not maintained or unexpected problems occur after the product reaches the market. Later discovery of previously unknown problems with a drug, including serious and/or unexpected adverse experiences, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies to assess new safety risks; or the imposition of distribution or other restrictions under a REMS.

We and/or our present or future suppliers, contract manufacturers, and/or other affiliates involved in one or more of our current or future U.S. development and/or commercialization activities (if applicable) may not be able to comply with all FDA regulatory requirements. For example, we may believe that all clinical studies are being conducted in accordance with the FDA’s IND regulations and that none of our investigational products are being promoted with claims of safety and/or effectiveness for the intended use(s) for which they are under investigation, but the FDA may determine otherwise, which could subject us to enforcement action and/or delay or prevent the ultimate approval of our applicable product candidate(s). From a post-market perspective, with regard to any products we may commercialize in the United States in the future, we may believe our manufacturing operations (including that of our partners and/or contractors, as applicable) are fully compliant with cGMPs and that all promotional communications disseminated by or on behalf of us are consistent with FDA’s prescription-drug marketing requirements, but the FDA may disagree and take enforcement action against us. Accordingly, we could be subject to a number of adverse enforcement actions and/or penalties in connection with any failure(s) to comply with the FDCA and/or its implementing regulations at any stage in development and/or commercialization (if applicable), including, but not limited to, the following:

We and our manufacturers and other partners in development and/or (future) commercialization, as applicable, also will be subject to regulation under the Occupational Safety and Health Act, the National Environmental Policy Act, the Nuclear Energy and Radiation Control Act, the Toxic Substance Control Act and the Resource Conservation and Recovery Act. We will also be subject to a variety of federal, state and local regulations relating to the use, handling, storage and disposal of hazardous materials, including chemicals and radioactive and biological materials.

We will also be subject to a variety of regulations governing clinical trials and sales of our products outside the U.S. Whether or not FDA approval has been obtained, approval of a product candidate by the comparable regulatory authorities of foreign countries and regions must be obtained prior to the commencement of marketing the product in those countries. The approval process varies from one regulatory authority to another and the time may be longer or shorter than that required for FDA approval. In the European Union, Canada and Australia, regulatory requirements and approval processes are similar, in principle, to those in the U.S.

Other U.S. Healthcare Laws and Regulations

Healthcare Reform Measures

On March 23, 2010, former President Obama signed the “Patient Protection and Affordable Care Act” (P.L. 111-148) (the “ACA”) and on March 30, 2010, he signed the “Health Care and Education Reconciliation Act” (P.L. 111-152), collectively commonly referred to as the “Healthcare Reform Law.” The Healthcare Reform Law included a number of new rules regarding health insurance, the provision of healthcare, conditions to reimbursement for healthcare services provided to Medicare and Medicaid patients, and other healthcare policy reforms. Through the law-making process, substantial changes have been and continue to be made to the current system for paying for healthcare in the U.S., including changes made to extend medical benefits to certain Americans who lacked insurance coverage and to contain or reduce healthcare costs (such as by reducing or conditioning reimbursement amounts for healthcare services and drugs, and imposing additional taxes, fees, and rebate obligations on pharmaceutical and medical device companies). This legislation was one of the most comprehensive and significant reforms ever experienced by the U.S. in the healthcare industry and has significantly changed the way healthcare is financed by both governmental and private insurers. This legislation has impacted the scope of healthcare insurance and incentives for consumers and insurance companies, among others. Additionally, the Healthcare Reform Law’s provisions were designed to encourage providers to find cost savings in their clinical operations. Pharmaceuticals represent a significant portion of the cost of providing care. This environment has caused changes in the purchasing habits of consumers and providers and resulted in specific attention to the pricing negotiation, product selection and utilization review surrounding pharmaceuticals. This attention may result in our current commercial products, products we may commercialize or promote in the future, and our therapeutic candidates, being chosen less frequently or the pricing being substantially lowered. At this stage, it is difficult to estimate the full extent of the direct or indirect impact of the Healthcare Reform Law on us.

These structural changes could entail further modifications to the existing system of private payors and government programs (such as Medicare, Medicaid, and the State Children’s Health Insurance Program), creation of government-sponsored healthcare insurance sources, or some combination of both, as well as other changes. Restructuring the coverage of medical care in the U.S. could impact the reimbursement for prescribed drugs and pharmaceuticals, including our current commercial products, those we and our development or commercialization partners are currently developing or those that we may commercialize or promote in the future. If reimbursement for the products we currently commercialize or promote, any product we may commercialize or promote, or approved therapeutic candidates is substantially reduced or otherwise adversely affected in the future, or rebate obligations associated with them are substantially increased, it could have a material adverse effect on our reputation, business, financial condition or results of operations.

Extending medical benefits to those who currently lack coverage will likely result in substantial costs to the U.S. federal government, which may force significant additional changes to the healthcare system in the U.S. Much of the funding for expanded healthcare coverage may be sought through cost savings. While some of these savings may come from realizing greater efficiencies in delivering care, improving the effectiveness of preventive care and enhancing the overall quality of care, much of the cost savings may come from reducing the cost of care and increased enforcement activities. Cost of care could be reduced further by decreasing the level of reimbursement for medical services or products (including our current commercial products, our development or commercialization partners or any product we may commercialize or promote, or those therapeutic candidates currently being developed by us), or by restricting coverage (and, thereby, utilization) of medical services or products. In either case, a reduction in the utilization of, or reimbursement for our current commercial products, any product we may commercialize or promote, or any therapeutic candidate, or for which we receive marketing approval in the future, could have a material adverse effect on our reputation, business, financial condition or results of operations.

Several states and private entities initially mounted legal challenges to the Healthcare Reform Law, in particular, the ACA, and they continue to litigate various aspects of the legislation. On July 26, 2012, the U.S. Supreme Court generally upheld the provisions of the ACA at issue as constitutional. However, the U.S. Supreme Court held that the legislation improperly required the states to expand their Medicaid programs to cover more individuals. As a result, states have a choice as to whether they will expand the number of individuals covered by their respective state Medicaid programs. Some states have not expanded their Medicaid programs and have chosen to develop other cost-saving and coverage measures to provide care to currently uninsured individuals. Many of these efforts to date have included the institution of Medicaid-managed care programs. The manner in which these cost-saving and coverage measures are implemented could have a material adverse effect on our reputation, business, financial condition or results of operations, particularly once we and/or any of our partners have products on the U.S. market, if ever.

Further, the healthcare regulatory environment has seen significant changes in recent years and is still in flux. Legislative initiatives to modify, limit, replace, or repeal the ACA and judicial challenges have continued. We cannot predict the extent to which our business may be impacted by legal challenges to the ACA or other aspects of the Healthcare Reform Law or other changes to the current laws and regulations. The financial impact of U.S. healthcare reform legislation over the next few years will depend on a number of factors, including the policies reflected in implementing regulations and guidance and changes in sales volumes for therapeutics affected by the legislation. From time to time, legislation is drafted, introduced and passed in the U.S. Congress that could significantly change the statutory provisions governing coverage, reimbursement, and marketing of pharmaceutical products. In addition, third-party payor coverage and reimbursement policies are often revised or interpreted in ways that may significantly affect our business and any products we or our partners may commercialize in the future, as well as the prospects and/or viability of our product candidates.

During his time in office, former President Trump supported the repeal of all or portions of the ACA. President Trump also issued an executive order in which he stated that it is his administration’s policy to seek the prompt repeal of the ACA and in which he directed executive departments and federal agencies to waive, defer, grant exemptions from, or delay the implementation of the provisions of the ACA to the maximum extent permitted by law. Congress has enacted legislation that repeals certain portions of the ACA, including but not limited to the Tax Cuts and Jobs Act, passed in December 2017, which included a provision that eliminates the penalty under the ACA’s individual mandate, effective January 1, 2019, as well as the Bipartisan Budget Act of 2018, passed in February 2018, which, among other things, repealed the Independent Payment Advisory Board (which was established by the ACA and was intended to reduce the rate of growth in Medicare spending).

Additionally, in December 2018, a district court in Texas held that the individual mandate is unconstitutional and that the rest of the ACA is, therefore, invalid. On appeal, the Fifth Circuit Court of Appeals affirmed the holding on the individual mandate but remanded the case back to the lower court to reassess whether and how such holding affects the validity of the rest of the ACA. The Fifth Circuit’s decision on the individual mandate was appealed to the U.S. Supreme Court. On June 17, 2021, the Supreme Court held that the plaintiffs (comprised of the state of Texas, as well as numerous other states and certain individuals) did not have standing to challenge the constitutionality of the ACA’s individual mandate and, accordingly, vacated the Fifth Circuit’s decision and instructed the district court to dismiss the case. As a result, the ACA will remain in-effect in its current form for the foreseeable future; however, we cannot predict what additional challenges may arise in the future, the outcome thereof, or the impact any such actions may have on our business.

The Biden administration also introduced various measures in 2021 focusing on healthcare and drug pricing, in particular. For example, on January 28, 2021, President Biden issued an executive order that initiated a special enrollment period for purposes of obtaining health insurance coverage through the ACA marketplace, which began on February 15, 2021, and remained open through August 15, 2021. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. On the legislative front, the American Rescue Plan Act of 2021 was signed into law on March 11, 2021, which, in relevant part, eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average manufacturer price, for single source drugs and innovator multiple source drugs, beginning January 1, 2024. And, in July 2021, the Biden administration released an executive order entitled, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response, on September 9, 2021, HHS released a “Comprehensive Plan for Addressing High Drug Prices” that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue as well as potential administrative actions HHS can take to advance these principles. And, in November 2021, President Biden announced the “Prescription Drug Pricing Plan” as part of the Build Back Better Act (H.R. 5376) passed by the House of Representatives on November 19, 2021, which aims to lower prescription drug pricing by, among other things, allowing Medicare to negotiate prices for certain high-cost prescription drugs covered under Medicare Part D and Part B after the drugs have been on the market for a certain number of years and imposing tax penalties on drug manufacturers that refuse to negotiate pricing with Medicare or increase drug prices “faster than inflation.” If enacted, this bill could have a substantial impact on our business. 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 product candidates. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

There is uncertainty as to what healthcare programs and regulations may be implemented or changed at the federal and/or state level in the U.S. or the effect of any future legislation or regulation. Furthermore, we cannot predict what actions the Biden administration will implement in connection with the Health Reform Law. However, it is possible that such initiatives could have an adverse effect on our or our partners’ ability to obtain approval for and/or successfully commercialize products in the U.S. in the future.

Fraud and Abuse, Transparency, and Privacy

In the United States, we may be subject to various federal and state laws and regulations regarding fraud and abuse in the healthcare industry, as well as industry standards and guidance, such as the codes issued by the Pharmaceutical Research and Manufacturers of America (or “PhRMA Codes”), which some states reference or incorporate in their statutes and regulations. These laws, regulations, standards, and guidance may impact, among other things, our sales and marketing activities and our relationships with healthcare providers and patients. In addition, we may be subject to patient privacy regulations by both the federal government and the states in which we conduct our business. The laws that may affect our ability to operate include but are not limited to:

Because of the breadth of these laws and the narrow scope of the statutory or regulatory exceptions and safe harbors available, our current or future activities, policies, and/or arrangements could be challenged under one or more of these laws. In addition, the federal government has identified relationships between drug companies (and other medical-product manufacturers) and healthcare providers as particularly susceptible to fraud and abuse and, thus, our relationships may be subject to heightened regulatory scrutiny, particularly once we have one or more products on the U.S. market, if ever. Further, many of the applicable healthcare laws and regulations are subject to varying and/or evolving interpretations, which makes achieving and maintaining consistent compliance more difficult. We may have to devote substantial costs, resources, and time to compliance efforts, particularly once one or more of our product candidates, or any other products to which we may obtain commercialization rights in the future, is marketed in the United States. If any of our past, current, or future operations and/or arrangements are found to be in violation of If our operations are found to be in violation of any healthcare laws or regulations that may apply to us, we may be subject to significant civil, criminal, and/or administrative penalties; damages; fines; personal imprisonment; exclusion from government-funded programs, such as Medicare and Medicaid; additional reporting requirements and oversight under a corporate integrity (or deferred prosecution or other similar) agreement with the applicable federal or state agency or agencies (such as the U.S. Office of Inspector General (“OIG”), the U.S. Department of Justice (“DOJ”), or state attorneys general); and/or the curtailment or restructuring of our operations. Any adverse enforcement action initiated against us based on actual or alleged violations of one or more of the healthcare laws and regulations could have a material adverse effect on our business, even if we are ultimately successful in defending against such claims.

General Risk Factors:

Risks Associated With Our Business

We have operated at a loss and will likely continue to operate at a loss for the foreseeable future.

We have operated at a loss due to our ongoing expenditures for research and development of our product candidates and for general and administrative purposes, and lack of significant recurring revenues. For the year ended December 31, 2023, we realized a net income of $0.4 million, had a loss from operations of $3.8 million , incurred a net loss of $4.2 million for the year ended December 31, 2022, and had total stockholders’ equity as of December 31, 2023 of $0.1 million. We have had no recurring revenue, and we are likely to continue to incur losses unless and until we conclude a successful strategic partnership or financing for our LADR™ technology. These losses, among other things, have had and will continue to have an adverse effect on our stockholders’ equity and working capital. Because of the numerous risks and uncertainties associated with our product development efforts, we are unable to predict when we may become profitable, if at all. If we do not become profitable or are unable to maintain future profitability, the market value of our common stock will be adversely affected. These factors individually and collectively raise a substantial doubt about our ability to continue as a going concern.

Our independent registered public accounting firm has included an explanatory paragraph in its report as of and for the year ended December 31, 2023 expressing substantial doubt in our ability to continue as a going concern based on our recurring and continuing losses from operations and our need for additional funding to continue operations. Our consolidated financial statements do not include any adjustments that might result from the outcome of this going concern uncertainty and have been prepared under the assumption that we will continue to operate as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. If we are unable to continue as a going concern, we may be forced to liquidate our assets which would have an adverse impact on our business and developmental activities. In such a scenario, the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our financial statements. The reaction of investors to the inclusion of a going concern statement by our independent registered public accounting firm and our potential inability to continue as a going concern may materially adversely affect our stock price and our ability to raise new capital or to enter into strategic alliances.

Because we have no source of significant recurring revenue, we must depend on capital raising to sustain our operations, and our ability to raise capital may be severely limited.

Developing products and conducting clinical trials require substantial amounts of capital. We need to raise additional capital to fund our general and administrative expenses and, if we determine to develop products based on our LADR™ technology platform, we will need to raise additional capital to fund development of product candidates, prepare, file, prosecute, maintain, enforce and defend patent and other proprietary rights, and develop and implement sales, marketing and distribution capabilities. However, capital raising has been significantly challenging.

At December 31, 2023, we had cash and cash equivalents of approximately $2.1 million. The continuation of the Company as a going concern is dependent upon its ability to obtain necessary debt or equity financing to continue operations until it begins generating positive cash flow. No assurance can be given that any future financing will be available or, if available, that it will be on terms that are satisfactory to us. Even if we are able to obtain additional financing, it may contain undue restrictions on our operations, in the case of debt financing or cause substantial dilution for our stockholders, in case of equity financing.

If we raise additional funds by issuing equity securities, dilution to stockholders may result and new investors could have rights superior to current equity holders. In addition, debt financing, if available, may include restrictive covenants. If adequate funds are not available to us, we may have to liquidate some or all of our assets or delay or reduce the scope of or eliminate some portion or all of our development programs. We also may have to license to other companies our product candidates or technologies that we would prefer to develop and commercialize ourselves.

If either Zevra or ImmunityBio fail to successfully develop and commercialize arimoclomol and aldoxorubicin, respectively, our business prospects will be materially adversely affected.

In June 2023, we entered into the Royalty Agreement with XOMA, for the sale, transfer, assignment and conveyance of our right, title and interest in and to certain royalty payments and milestone payments with respect to aldoxorubicin, and the Assignment Agreement with XOMA for the sale, transfer, assignment and conveyance of our right, title and interest in the 2011 Arimoclomol Agreement between us and Orphazyme and assigned to Zevra Denmark, effective as of June 1, 2022, which includes certain royalty and milestone payments with respect to arimoclomol. Under this Royalty Agreement, we are entitled to (i) a one-time payment of $1 million upon acceptance of a re-submission of a NDA to the FDA for arimoclomol, and a one-time payment of $1 million upon first invoiced sale in certain territories of a pharmaceutical product derived from arimoclomol as an active pharmaceutical ingredient, subject to the receipt of the applicable regulatory approval required to sell such a product in such countries. In January 2024, Zevra announced the FDA had accepted the NDA for arimoclomol, and we received the one-time payment of $1 million in February 2024.

Pursuant to the Royalty Agreement, we also agreed to sell, transfer, assign and convey to XOMA, among other payments, all royalty payments and regulatory and commercial milestone payments payable to us pursuant to the 2017 License Agreement. The Royalty Agreement also provides for the sharing of certain rights with XOMA to bring any action, demand, proceeding or claim as related to receiving such payments and $4 million upon FDA approval of aldoxorubicin.

The potential revenue from our arrangement with Zevra and ImmunityBio is based on contingent payments, which will depend upon their ability to achieve regulatory approvals and successfully market and sell products derived from arimoclomol and aldoxorubicin. We will not be involved in this process and will depend entirely on Zevra and ImmunityBio, which may fail to develop or effectively commercialize products derived from arimoclomol and aldoxorubicin, respectively, for many reasons, including if they:

● decide not to devote the necessary resources due to internal constraints, such as limited personnel with the requisite scientific expertise, limited cash resources or specialized equipment limitations, or the belief that other drug development programs may have a higher likelihood of obtaining regulatory approval or may potentially generate a greater return on investment;

● do not have sufficient resources necessary to carry arimoclomol or aldoxorubicin through clinical development, regulatory approval and commercialization;

● cannot obtain the necessary regulatory approvals for arimoclomol or aldoxorubicin; or

● decide to pursue a competitive drug candidate.

If Zevra or ImmunityBio do not obtain the applicable regulatory approvals for arimoclomol or aldoxorubicin that are necessary to trigger the corresponding milestone payments to us under our the Royalty Agreement and the Assignment Agreement, if their research and development or commercialization efforts are, otherwise, unsuccessful, or if they fail to develop or effectively commercialize arimoclomol or aldoxorubicin for any of the other reasons described above, we may not be able to develop and commercialize that drug independently or replace Zevra or ImmunityBio with another suitable partner in a reasonable period of time, and we will not realize the anticipated commercial benefits of the arrangement which could adversely affect our business prospects and financial condition.

Risks Associated With Drug Discovery and Development

If the projected development goals for our product candidates are not achieved in the expected time frames, the commercialization of our products may be delayed and our business prospects may suffer. Our financial projections also may prove to be materially inaccurate.

From time to time, we estimate the timing of the accomplishment of various scientific, clinical, regulatory and other product development goals, which we sometimes refer to as milestones. These milestones may include the commencement or completion of scientific studies and clinical trials and the submission of regulatory filings.

We also may disclose projected expenditures or other forecasts for future periods. These and other financial projections are based on management’s current expectations and do not contain any margin of error or cushion for any specific uncertainties, or for the uncertainties inherent in all financial forecasting.

The actual timing of milestones and actual expenditures or other financial results can vary dramatically compared to our estimates, in some cases for reasons beyond our control or the control of companies that have licensed or purchased our product candidates. If these milestones or financial projections are not met, the development and commercialization of our product candidates may be delayed and our business prospects may suffer. The assumptions management has used to produce these projections may significantly change or prove to be inaccurate. Accordingly, you should not unduly rely on any of these financial projections.

The regulatory approval process is lengthy, time consuming and inherently unpredictable, and if our products or those we have sold or licensed are not successfully developed and approved by the FDA or foreign regulatory authorities, we may be forced to reduce or curtail our operations.

All of our product candidates in development or those licensed or sold must be approved by the FDA or corresponding foreign governmental agencies before they can be marketed. The process for obtaining FDA and foreign government approvals is both time-consuming and costly, with no certainty of a successful outcome. This process typically includes the conduct of extensive pre-clinical and clinical testing, including post-approval testing, which may take longer or cost more than we or our licensees, if any, anticipate, and may prove unsuccessful due to numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions. None of our product candidates in development or licensed or sold to third parties have received regulatory approval.

Numerous factors could affect the timing, cost or outcome of product development efforts, including the following:

It is possible that none of the product candidates we develop or have sold or licensed will obtain the regulatory approvals necessary for us to begin selling them or making us eligible to receive milestone or royalty payments. The time required to obtain FDA and foreign governmental approvals is unpredictable, but often can take years following the commencement of clinical trials, depending upon the complexity of the product candidate. Any analysis performed on data from clinical activities is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. In addition, even if regulatory approval was obtained, regulatory authorities may approve any product candidates for fewer or more limited indications than requested, may not approve the intended price for such products, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate. Any of the foregoing scenarios could materially harm the commercial prospects for the product candidates that we develop, have sold or licensed.

Furthermore, even if regulatory approvals are obtained, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, import, export, advertising, promotion and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with current good manufacturing practices (“cGMPs”), and good clinical practices (“cGCPs”), for any clinical trials that we conduct post-approval. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

The FDA’s policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability, which would adversely affect our business. We will also be subject to periodic inspections and the potential for mandatory post- approval clinical trials required by the FDA and other U.S. and foreign regulatory authorities. Any delay or failure in obtaining required approvals or to comply with post-approval regulatory requirements could have a material adverse effect on our ability to generate revenue from the particular product candidate. The failure to comply with any post-approval regulatory requirements also could result in the rescission of the related regulatory approvals or the suspension of sales of the offending product.

Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results.

Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. The results of preclinical studies and early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. Product candidates in later stages of clinical development may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or safety profiles, notwithstanding promising results in earlier trials. For example, aldoxorubicin has shown encouraging preliminary clinical results in our Phase 2b clinical trial as a treatment for STS. These conclusions may not be reproduced in future clinical trial results. For instance, the Phase 3 pivotal clinical trial testing aldoxorubicin as a treatment for STS narrowly missed statistical significance although it demonstrated a statistically significant improvement in PFS over investigator’s choice in 312 patients treated in North America and Australia. Accordingly, our development partner may ultimately be unable to provide the FDA and/or other U.S. and foreign regulatory authorities with satisfactory data on clinical safety and efficacy sufficient to obtain approval from the FDA of aldoxorubicin for any indication.

Further delays may occur in clinical trials of product candidates. We do not know whether ongoing clinical trials will be completed on schedule or at all, or whether planned clinical trials will begin on time, need to be redesigned, enroll patients on time or be completed on schedule, if at all. Clinical trials can be delayed for a variety of reasons, including delays related to:

We may be unable to protect our intellectual property rights, which could adversely affect our ability to compete effectively.

We will be able to protect our technologies from unauthorized use by third parties only to the extent that we have rights to valid and enforceable patents or other proprietary rights that cover them. Although we have rights to patents and patent applications directed to our product candidates, these patents and applications may not prevent third parties from developing or commercializing similar or identical technologies. In addition, our patents may be held to be invalid if challenged by third parties, and our patent applications may not result in the issuance of patents.

The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. No consistent policy regarding the breadth of claims allowed in biotechnology patents has emerged to date in the United States and in many foreign countries. The application and enforcement of patent laws and regulations in foreign countries is even more uncertain. Accordingly, we may not be able to effectively file, protect or defend our proprietary rights on a consistent basis. Many of the patents and patent applications on which we rely were issued or filed by third parties prior to the time we acquired rights to them. The validity, enforceability and ownership of those patents and patent applications may be challenged, and if a court decides that our patents are not valid, we will not have the right to stop others from using our inventions. There is also the risk that, even if the validity of our patents is upheld, a court may refuse to stop others on the ground that their activities do not infringe our patents.

Any litigation brought by us to protect our intellectual property rights could be costly and have a material adverse effect on our operating results or financial condition, make it more difficult for us to enter into strategic alliances with third parties to develop our products, or discourage our existing licensees from continuing their development work on our potential products. If our patent coverage is insufficient to prevent third parties from developing or commercializing similar or identical technologies, the value of our assets is likely to be materially and adversely affected.

Moreover, we may be subject to a third-party pre-issuance submission of prior art or become involved in opposition, derivation, reexamination, inter partes review, post-grant review or interference proceedings challenging our patent rights or the patent rights of others. The costs of defending our patents or enforcing our proprietary rights in post-issuance administrative proceedings and litigation can be substantial and the outcome can be uncertain. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, 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. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.

We have not pursued or maintained, and may not pursue or maintain in the future, patent protection for our product candidates in every country or territory in which we may sell our products, if approved. The laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from infringing our patents in all countries outside the United States, or from selling or importing products that infringe our patents in and into the United States or other jurisdictions.

Indeed, several companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of some countries do not favor the enforcement of patents and other intellectual property rights, which could make it difficult for us to stop the infringement, misappropriation or other violation of our intellectual property rights generally. Proceedings to enforce our intellectual property rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, 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, 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 abroad. Such challenges may result in 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. 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 intellectual property may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

Moreover, the scope claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Changes in either the patent laws or interpretation of the patent laws may diminish the value of our or our collaborators’ patents or narrow the scope of such patent protection and could increase the uncertainties and costs surrounding the prosecution of our or any future collaborators’ patent applications and the enforcement or defense of any issued patents. Even if the patent applications we license or own do 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. Our competitors or other third parties may be able to circumvent our patents by developing similar or alternative products in a non-infringing manner.

Some of our technologies and processes do not fulfill the requirements for patent or trademark protection or are not protected by patent or trademark rights for other reasons, e.g., secrecy. We therefore also rely on certain proprietary trade secrets and know-how, especially where we believe patent protection is not appropriate or obtainable. Trade secrets and know-how are difficult to protect. Although we have taken measures to protect our unpatented trade secrets and know-how, including the use of confidentiality and invention assignment agreements with our employees, consultants and some of our contractors, it is possible that these persons may disclose our trade secrets or know-how or that our competitors may independently develop or otherwise discover our trade secrets and know-how.

There is no guarantee, however, that such agreements will not be breached, that they will provide sufficient protection for our business secrets and proprietary information or that adequate remedies will be available in the event of an unauthorized use or disclosure of such information. It cannot be excluded that we do not have, or cannot enforce, legal remedies that are effective at economically acceptable costs. Further, the violation of a non-disclosure agreement might be difficult to prove because business secrets and know- how may be developed independently by, or become otherwise known to, third parties. In addition, it may be difficult to quantify the damages which have occurred and to obtain legal remediation, or to undo the damages caused, by legal remedies. Our failure to effectively protect our business secrets and know-how could have material adverse effects on our business, prospects, financial condition and results of operations.

If our product candidates infringe or otherwise violate the rights of others, we could be subject to expensive litigation or be required to obtain licenses from others to develop or market them.

Our commercial success also depends upon our ability, and the ability of any third party with which we may partner, to develop, manufacture, market and sell our product candidates and/or products, if approved, and use our patent-protected technologies without infringing the patents of third parties. There is considerable patent litigation in the biotechnology and pharmaceutical industries. As the biopharmaceutical industry expands and more patents are issued, we face increased risks that there may be patents issued to third parties that relate to our product candidates and technology of which we are not aware or that we must challenge to continue our operations as currently contemplated.

Our competitors or others may have patent rights that they choose to assert against us or our licensees, suppliers, customers or potential collaborators. Moreover, we may not know about patents or patent applications that our products would infringe. For example, because patent applications do not publish for at least 18 months, if at all, and can take many years to issue, there may be currently pending applications unknown to us that may later result in issued patents that our product candidates would infringe. In addition, if third parties file patent applications or obtain patents claiming technology also claimed by us or our licensors in issued patents or pending applications, we may have to participate in interference proceedings in the U.S. Patent and Trademark Office to determine priority of invention. If third parties file oppositions in foreign countries, we may also have to participate in opposition proceedings in foreign tribunals to defend the patentability of our foreign patent applications.

If a third-party claims that we are infringing on its proprietary rights, any of the following may occur:

If any of these events occurs, our business and prospects will suffer and the market price of our common stock will likely decline substantially.

Obtaining and maintaining patent protection depends on compliance with various procedures and other requirements, and our patent protection could be reduced or eliminated in case of non-compliance with these requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to the relevant patent agencies in several stages over the lifetime of the patents and /or applications. The relevant patent agencies require compliance with a number of procedural, documentary, fee payment and other provisions during the patent application process. In many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. However, there are situations in which the failure to comply with the relevant requirements can result in the abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, our competitors might be able to use our technologies and know-how which could have a material adverse effect on our business, prospects, financial condition and results of operation.

If we fail to comply with our obligations under our license agreements, we could lose the rights to intellectual property that is important to our business.

Our current license agreements impose on us various development obligations, payment of royalties and fees based on achieving certain milestones as well as other obligations. If we fail to comply with our obligations under these agreements, the licensor may have the right to terminate the license. In addition, if the licensor fails to enforce its intellectual property, the licensed rights may not be adequately maintained. The termination of any license agreements or failure to adequately protect such license agreements could prevent us from commercializing our product candidates or possible future products covered by the licensed intellectual property. Any of these events could materially adversely affect our business, prospects, financial condition and results of operation.

We may be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

Our employees may have been previously employed at other companies in the industry, including our competitors or potential competitors. Although we are not aware of any claims currently pending against us, we may be subject to claims that these employees or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of the former employers of our employees. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management. If we fail in defending such claims, in addition to paying money claims, we may lose valuable intellectual property rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize product(s), which would materially adversely affect our commercial development efforts.

The results of pre-clinical studies or early clinical trials are not necessarily predictive of future results, and our ultra-high potency albumin-binding drug conjugates may not have favorable results in later clinical trials or receive regulatory approval.

Success in pre-clinical studies and early clinical trials does not ensure that later clinical trials will generate adequate data to demonstrate the efficacy and safety of our ultra-high potency albumin-binding drug conjugates. A number of companies in the pharmaceutical and biotechnology industries, including those with greater resources and experience than we have, have suffered significant setbacks in clinical trials, even after seeing promising results in earlier clinical trials. We do not know whether the clinical trials we may conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market them in any particular jurisdiction. If our clinical trials do not produce favorable results, our ability to achieve regulatory approval for these drug candidates will be adversely impacted and the value of our stock may decline.

The successful commercialization of our product candidates that are approved for marketing in the United States, if any, and/or any other products that we or our partners may commercialize in the future will likely depend, in-part, on the coverage and reimbursement policies of third-party payors, which, if unfavorable, could have a material adverse effect on our business.

The commercial success of our product candidates that are approved for marketing in the United States, if any, as well as any other products that we may or our partners may commercialize in the future, may depend, in significant part, on the extent to such products will be covered and reimbursed by third-party payors, including government healthcare programs, such as Medicare and Medicaid, private insurers, and managed care organizations. Patients for whom prescription drugs are prescribed and prescribing practitioners generally rely on third-party payors to reimburse all or part of the associated healthcare costs. Without adequate coverage and reimbursement, patients and providers are unlikely to use or prescribe any products that we or our partners may commercialize or from which we may, otherwise, generate revenue in connection with commercial sales.

There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products. In the United States, there is no uniform policy of coverage and reimbursement. Accordingly, third-party payors, including private insurers and governmental payors, such as Medicare and Medicaid, play an important role in determining the extent to which new drugs and biologics will be covered and reimbursed. The Medicare program covers certain individuals aged 65 or older, as well as certain people under 65 with disabilities and individuals suffering from end-stage renal disease. The Medicaid program, which varies from state-to-state, covers eligible individuals and families who have limited financial means. The Medicare and Medicaid programs are increasingly used as models for how private payors and other governmental payors develop their coverage and reimbursement policies for drugs and biologics. It is difficult to predict at this time what third-party payors will decide with respect to the coverage and reimbursement for our product candidates and any other products we or our partners may commercialize or to which we may have commercialization rights or interests.

Third-party payors may deny coverage or reimbursement if they determine that a medical product was not used in accordance with cost-effective treatment methods, as determined by the third-party payor, and most, if not all, payors will deny coverage for products used or administered for an unapproved indication. Third-party payors also typically refuse to cover and reimburse for experimental procedures and devices. Furthermore, third-party payors are increasingly challenging the prices charged for medical products and services. And, the U.S. government and state legislatures have shown significant interest in implementing healthcare cost-containment programs, including price controls, restrictions on reimbursement, discount and rebate requirements, and requirements for substitution of generic products. Such measures, and the enactment of any more restrictive updates thereto and/or new measures could further limit our potential profitability and commercial success in connection with any products we or our partners may market in the United States. We cannot predict whether, or the extent to which, government and/or private payors will cover any products we or our partners may commercialize in the future, and there can be no assurances that such coverage and reimbursement levels, as applicable, will be sufficient to allow us to profit from the commercial sale of such product(s) in light of our costs from development and other related activities and any current or future arrangements with our development and/or commercialization partners.

Any products that we develop or are sold or licensed may become subject to unfavorable pricing regulations and/or third-party coverage and reimbursement policies, which could have a material adverse effect on our business.

Our product candidates are intended to be marketed primarily to hospitals, which generally receive reimbursement for the health care services they provide to their patients from third-party payors, such as Medicare, Medicaid and other domestic and international government programs, private insurance plans and managed care programs.

Such drugs will likely need to be administered under the supervision of a physician. Under currently applicable law, drugs that are not usually self-administered may be eligible for coverage by the Medicare program if:

There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products. In the United States, third-party payors, including private and governmental payors, such as the Medicare and Medicaid programs, play an important role in determining the extent to which new drugs and biologics will be covered and reimbursed. The Medicare program covers certain individuals aged 65 or older, disabled or suffering from end-stage renal disease. The Medicaid program, which varies from state-to-state, covers certain individuals and families who have limited financial means. The Medicare and Medicaid programs increasingly are used as models for how private payors and other governmental payors develop their coverage and reimbursement policies for drugs and biologics. It is difficult to predict at this time what third-party payors will decide with respect to the coverage and reimbursement for our product candidates.

Most third-party payors may deny coverage or reimbursement if they determine that a medical product was not used in accordance with cost-effective treatment methods, as determined by the third-party payor, or was used for an unapproved indication. Third-party payors also may refuse to cover and reimburse for experimental procedures and devices. Furthermore, because our programs are in the early stages of development, we are unable at this time to determine their cost-effectiveness and the level or method of reimbursement. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices, and are challenging the prices charged for medical products. If the price we are able to charge for any products we develop is inadequate in light of our development and other costs, our profitability could be adversely affected.

Healthcare legislative reform measures could hinder or prevent the commercial success of our products and product candidates.

In the United States, there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the healthcare system that could affect our future revenues and profitability. Federal and state lawmakers regularly propose and, at times, enact legislation that results in significant changes to the healthcare system, some of which are intended to contain or reduce the costs of medical products and services. For example, in March 2010, the Patient Protection and Affordable Care Act (the “ACA”), as amended by the Health Care and Education Reconciliation Act, or collectively, the “Healthcare Reform Law,” became law in the United States. It contains a number of provisions regarding health insurance, the provision of healthcare, conditions to reimbursement for healthcare services provided to Medicare and Medicaid patients, and other healthcare policy reforms. Through the law-making process, substantial changes have been and continue to be made to the current system for paying for healthcare in the United States, including changes made to extend medical benefits to certain Americans who lacked insurance coverage and to contain or reduce healthcare costs (such as by reducing or conditioning reimbursement amounts for healthcare services and drugs, and imposing additional taxes, fees, and rebate obligations on pharmaceutical and medical device companies). This legislation was one of the most comprehensive and significant reforms ever experienced by the United States in the healthcare industry and has significantly changed the way healthcare is financed by both governmental and private insurers. This legislation has impacted the scope of healthcare insurance and incentives for consumers and insurance companies, among others. Additionally, the Healthcare Reform Law’s provisions were designed to encourage providers to find cost savings in their clinical operations. Pharmaceuticals represent a significant portion of the cost of providing care. This environment has caused changes in the purchasing habits of consumers and providers and resulted in specific attention to the pricing negotiation, product selection and utilization review surrounding pharmaceuticals. This attention may result in any products we may commercialize or promote in the future, and/or our therapeutic candidates, as applicable, being chosen less frequently or subject to substantially lowered pricing.

These structural changes could entail further modifications to the existing system of private payors and government programs (such as Medicare, Medicaid, and the State Children’s Health Insurance Program), creation of government-sponsored healthcare insurance sources, or some combination of both, as well as other changes. Restructuring the coverage of medical care in the U.S. could impact the reimbursement for prescribed drugs and pharmaceuticals, including our current commercial products, those we and our development or commercialization partners are currently developing or those that we may commercialize or promote in the future. If reimbursement for the products we currently commercialize or promote, any product we may commercialize or promote, or approved therapeutic candidates is substantially reduced or otherwise adversely affected in the future, or rebate obligations associated with them are substantially increased, it could have a material adverse effect on our reputation, business, financial condition or results of operations.

Further, there has been heightened governmental scrutiny over the manner in which drug manufacturers set prices for their marketed products, which have resulted in several recent Congressional inquiries and proposed and enacted bills designed to, among other things, bring more transparency to prescription drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. In addition, the United States government, state legislatures, and foreign governments have shown significant interest in implementing drug cost containment programs, including price-controls, restrictions on reimbursement and requirements for substitution of generic products for branded prescription drugs to limit the growth of government paid health care costs. For example, the United States government has passed legislation requiring pharmaceutical manufacturers to provide rebates and discounts to certain entities and governmental payors to participate in federal healthcare programs. Further, Congress and the current administration have each indicated that it will continue to seek new legislative and/or administrative measures to control drug costs, and the current administration recently released a “Blueprint”, or plan, to reduce the cost of drugs. The current administration’s Blueprint contains certain measures that the U.S. Department of Health and Human Services is already working to implement. Individual states in the United States have also been increasingly passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

We anticipate there will continue to be proposals by legislators at both the federal and state levels, regulators and commercial payers to reduce prescription drug costs while expanding individual healthcare benefits. Additional changes that may affect our business include those governing enrollment in federal healthcare programs, reimbursement changes, fraud and abuse enforcement, and expansion of new programs, such as Medicare payment for performance initiatives. The ultimate implementation of any healthcare reform legislation and any new laws and regulations, and its impact on us, is impossible to predict. Any significant reforms made to the healthcare system in the United States, or in other jurisdictions, may have an adverse effect on our business, financial condition, results of operations and prospects.

We may also be subject to federal and state healthcare laws and regulations relating to our current and/or future operations, and our failure to comply with those laws could adversely affect our business, operations and financial condition.

If we obtain FDA approval for any of our product candidates and begin commercializing those products in the United States, our operations may be directly, or indirectly through our customers, subject to various federal and state fraud and abuse laws, including, without limitation, the federal Anti-Kickback Statute, the federal False Claims Act, and physician sunshine laws and regulations. These laws may impact, among other things, our proposed sales, marketing, and education programs. In addition, we may be subject to patient privacy regulation by both the federal government and the states in which we conduct our business. The laws that may affect our ability to operate include:

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. In addition, the federal government has identified relationships between drug companies (and other medical-product manufacturers) and healthcare providers as particularly susceptible to fraud and abuse and, thus, our relationships may be subject to heightened regulatory scrutiny, particularly once we have one or more products on the U.S. market, if ever. Further, many of the applicable healthcare laws and regulations are subject to varying and/or evolving interpretations, which makes achieving and maintaining consistent compliance more difficult.

Achieving and sustaining compliance with these laws may prove costly. In addition, any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines, the exclusion from participation in federal and state healthcare programs, imprisonment, or the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results.

We will be required to pay substantial milestone and other payments relating to the commercialization of our products.

The agreement relating to our worldwide rights to arimoclomol provides for our payment of up to an aggregate of $3.65 million upon receipt of milestone payments from Orphayzme A/S. On May 31, 2022, Orphazyme announced that it had completed the sale of substantially all of its assets and business activities for cash consideration of $12.8 million and assumption of liabilities estimated to equal approximately $5.2 million to KemPharm, a specialty biopharmaceutical company focused on the discovery and development of novel treatments for rare CNS diseases. As part of the KemPharm Transaction, all of Orphazyme’s obligations to LadRx under the 2011 Arimoclomol Agreement, including with regard to milestone payments and royalties on sales, were assumed by KemPharm.

As part of the Royalty Purchase Agreement entered into with XOMA in June 2023, XOMA assumes all but $0.4 million of the payment due under the preceding agreement.

The COVID-19 endemic and its ongoing effects could adversely impact our business and prospects, including active and planned clinical trials by ImmunityBio and Zevra.

In May 2023, the World Health Organization determined that COVID-19 no longer fit the definition of a public health emergency and the declaration of a public health emergency associated with COVID-19 subsequently expired on May 11, 2023.

As the COVID-19 endemic and its ongoing effects continue to evolve, the companies which we are working to develop and commercialize our products, ImmunityBio and Zevra, could be materially and adversely affected by the risks, or the public perception of the risks, related to the COVID-19 endemic and its ongoing effects, including but not limited to, reinstatement of government-imposed quarantines, limitations on business activity and shelter-in-place mandates to mitigate or contain the virus, which could cause delays in our potential timing of receipts of milestones and royalties within the disclosed time periods and expected costs. The disruptions to ImmunityBio and Zevra could include:

The extent to which the COVID-19 endemic and its ongoing effects may impact our business and prospects will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the duration of the endemic, new variants of the coronavirus, reinstatement of travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease.

In the event of a dispute regarding our international drug development, it may be necessary for us to resolve the dispute in the foreign country of dispute, where we would be faced with unfamiliar laws and procedures.

The resolution of disputes in foreign countries can be costly and time consuming, similar to the situation in the United States. In a foreign country, we face the additional burden of understanding unfamiliar laws and procedures. We may not be entitled to a jury trial, as we might be in the United States. Further, to litigate in any foreign country, we would be faced with the necessity of hiring lawyers and other professionals who are familiar with the foreign laws. For these reasons, we may incur unforeseen expenses if we are forced to resolve a dispute in a foreign country.

Drug discovery is a complex, time-consuming and expensive process, and we may not succeed in creating new product candidates.

Conducting drug discovery and pre-clinical development of our albumin-binding technology is a complex and expensive process that will take many years. Accordingly, we cannot be sure whether or when our drug discovery and pre-clinical development activities will succeed in developing any new product candidates. In addition, any product candidates that we develop in pre-clinical testing may not demonstrate success in clinical trials required for marketing approval.

Any deficiency in the design, implementation or oversight of our drug discovery and pre-clinical testing programs could cause us to incur significant additional costs, experience significant delays, prevent us from obtaining marketing approval for any product candidate that may result from these programs or abandon development of certain product candidates. If any of these risks materializes, it could harm our business and cause our stock price to decline.

General Risk Factors

We are subject to intense competition, and we may not compete successfully.

Many companies, including large pharmaceutical and biotechnology firms with financial resources, research and development staffs, and facilities that may be substantially greater than those of ours or our strategic partners or licensees, are engaged in the research and development of pharmaceutical products that could compete with our potential products. To the extent that we seek to acquire, through license or otherwise, existing or potential new products, we will be competing with numerous other companies, many of which will have substantially greater financial resources and large acquisition staffs that may give those companies a competitive advantage over us in identifying and evaluating these drug acquisition opportunities. Any products that we acquire will be competing with products marketed by companies that in many cases will have substantially greater marketing resources than we have. The industry is characterized by rapid technological advances and competitors may develop their products more rapidly and such products may be more effective than those currently under development or that may be developed in the future by our strategic partners or licensees. Competitive products for a number of the disease indications that we have targeted are currently being marketed by other parties, and additional competitive products are under development and may also include products currently under development that we are not aware of or products that may be developed in the future.

As a result, these competitors may:

● succeed in developing competitive products sooner than us or our strategic partners or licensees;

● obtain FDA or foreign governmental approvals for their products before we can obtain approval of any of our products;

● obtain patents that block or otherwise inhibit the development and commercialization of our product candidate candidates;

● develop products that are safer or more effective than our products;

● devote greater resources than us to marketing or selling products;

● introduce or adapt more quickly than us to new technologies and other scientific advances;

● introduce products that render our products obsolete;

● withstand price competition more successfully than us or our strategic partners or licensees;

● negotiate third-party strategic alliances or licensing arrangements more effectively than us; and

● take better advantage than us of other opportunities.

We are subject to potential liabilities from clinical testing and future product liability claims.

If any of our products are alleged to be defective, they may expose us to claims for personal injury by patients in clinical trials of our products or, if we obtain marketing approval and commercialize our products, by patients using our commercially marketed products. Even if one or more of our products is approved by the FDA, users may claim that such products caused unintended adverse effects. We maintain clinical trial insurance for our ongoing clinical trials, and we plan to seek to obtain similar insurance for any other clinical trials that we conduct. We also would seek to obtain product liability insurance covering the commercial marketing of our product candidates. We may not be able to obtain additional insurance, however, and any insurance obtained by us may prove inadequate in the event of a claim against us. Any claims asserted against us also may divert management’s attention from our operations, and we may have to incur substantial costs to defend such claims even if they are unsuccessful.

We may be unable to successfully acquire additional technologies or products. If we require additional technologies or products, our product development plans may change and the ownership interests of our shareholders could be diluted.

We may seek to acquire additional technologies by licensing or purchasing such technologies, or through a merger or acquisition of one or more companies that own such technologies. We have no current understanding or agreement to acquire any technologies, however, and we may not be able to identify or successfully acquire any additional technologies. We also may seek to acquire products from third parties that already are being marketed or have been approved for marketing, although we have not currently identified any of these products. We do not have any prior experience in acquiring or marketing products approved for marketing and may need to find third parties to market any products that we might acquire.

We have focused our product development efforts on our oncology and neurodegenerative drug candidates, which we believe have the greatest revenue potential. If we acquire additional technologies or product candidates, we may determine to make further changes to our product development plans and business strategy to capitalize on opportunities presented by the new technologies and product candidates.

We may determine to issue shares of our common stock to acquire additional technologies or products or in connection with a merger or acquisition of another company. To the extent we do so, the ownership interest of our stockholders will be diluted accordingly.

The impact and results of our exploration of any strategic alternatives are uncertain and may not be successful.

From time to time, we may consider strategic alternatives available to us to enhance shareholder value. Strategic alternatives could include acquisition transactions and/or strategic partnerships with one or more parties, the licensing of some of our proprietary technologies, or other possible transactions. Any strategic transaction that is completed ultimately may not deliver the anticipated benefits or enhance shareholder value. Further, we may devote a significant amount of our management resources to such a transaction, which could negatively impact our operations. We may incur significant costs in connection with seeking certain acquisitions or other strategic opportunities regardless of whether the transaction is completed, which could materially and adversely affect our liquidity and capital resources. In the event that we consummate an acquisition or strategic alternative in the future, there is no assurance that we would fully realize the potential benefits of such a transaction. Integration may be difficult and unpredictable, and acquisition-related integration costs, including certain non-recurring charges, could materially and adversely affect our results of operations. Moreover, integrating assets and businesses may significantly burden management and internal resources, including the potential loss or unavailability of key personnel. If we fail to successfully integrate any assets and businesses we acquire, we may not fully realize the potential benefits we expect, and our operating results could be adversely affected. If we pay for an acquisition in cash, it would reduce our cash available for operations or cause us to incur additional debt, and if we pay with our stock it could be dilutive to our stockholders.

We rely significantly on information technology and any failure, inadequacy, interruption or security lapse of that technology, including any cybersecurity incidents, could harm our ability to operate our business effectively.

We rely significantly on information technology and any failure, inadequacy, interruption or security lapse of that technology, including any cybersecurity incidents, could harm our ability to operate our business effectively. We maintain sensitive data pertaining to our Company on our computer networks, including information about our development activities, our intellectual property and other proprietary business information. Our internal computer systems and those of third parties with which we contract may be vulnerable to damage from cyber-attacks, computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures, despite the implementation of security measures. System failures, accidents or security breaches could cause interruptions to our operations, including material disruption of our development activities, result in significant data losses or theft of our intellectual property or proprietary business information, and could require substantial expenditures to remedy. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications or inappropriate disclosure of confidential or proprietary information, we could incur liability and our development programs could be delayed, any of which would harm our business and operations.

Our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Natural disasters could severely disrupt our operations or the operations of manufacturing facilities and have a material adverse effect on our business, financial condition, results of operations and prospects. If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters, that damaged critical infrastructure, such as manufacturing facilities, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. The disaster recovery and business continuity plans we have in place currently are limited and may not prove adequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Global, market and economic conditions may negatively impact our business, financial condition and share price.

Concerns over inflation, geopolitical issues, the U.S. financial markets, foreign exchange rates, capital and exchange controls, unstable global credit markets and financial conditions and the COVID-19 endemic and its ongoing effects, have led to periods of significant economic instability, declines in consumer confidence and discretionary spending, diminished expectations for the global economy and expectations of slower global economic growth going forward, and increased unemployment rates. Our general business strategy may be adversely affected by any such economic downturns, volatile business environments and continued unstable or unpredictable economic and market conditions. If these conditions continue to deteriorate or do not improve, it may make any necessary debt or equity financing more difficult to complete, more costly, and more dilutive. In addition, there is a risk that one or more of our current or future service providers and other partners could be negatively affected by difficult economic times, which could adversely affect our ability to attain our operating goals on schedule and on budget or meet our business and financial objectives.

In addition, we face several risks associated with international business and are subject to global events beyond our control, including war, public health crises, such as endemics and epidemics, trade disputes, economic sanctions, trade wars and their collateral impacts and other international events. Any of these changes could have a material adverse effect on our reputation, business, financial condition or results of operations. There may be changes to our business if there is instability, disruption or destruction in a significant geographic region, regardless of cause, including war, terrorism, riot, civil insurrection or social unrest; and natural or man-made disasters, including famine, flood, fire, earthquake, storm or disease. In February 2022, armed conflict escalated between Russia and Ukraine. The sanctions announced by the United States and other countries, following Russia’s invasion of Ukraine against Russia to date include restrictions on selling or importing goods, services or technology in or from affected regions and travel bans and asset freezes impacting connected individuals and political, military, business and financial organizations in Russia. The United States and other countries could impose wider sanctions and take other actions should the conflict further escalate. It is not possible to predict the broader consequences of this conflict, which could include further sanctions, embargoes, regional instability, geopolitical shifts and adverse effects on macroeconomic conditions, currency exchange rates and financial markets, all of which could impact our business, financial condition and results of operations.

We may be subject to inflationary risk

The Company does not believe that inflation has had a material effect on its operations to date, other than the impact of inflation on the general economy. However, there is a risk that the Company’s operating costs could become subject to inflationary pressures in the future, which would have the effect of increasing the Company’s operating costs, and which would put additional stress on the Company’s working capital resources.

We may not be successful in hiring and retaining key employees, which may harm our business.

Our business is highly dependent upon the continued services of our senior management and key personnel. As such, our future success depends on our ability to identify, attract, hire or engage, retain, and motivate well-qualified personnel. Our operations require qualified personnel with expertise in pharmaceutical development and clinical research. We must compete for qualified individuals with numerous companies, universities, and other research institutions. Competition for such individuals is intense, and, when the need arises, we may not be able to hire the personnel necessary to support our efforts. There can be no assurance that these professionals will be available in the market, or that we will be able to retain existing professionals or to meet or to continue to meet their compensation requirements.

An overall tightening and increasingly competitive labor market in the U.S. employment market generally, especially in response to the COVID-19 endemic, has been observed in the United States. Sustained labor shortage or increased turnover rates within our employee base, caused by the COVID-19 endemic or as a result of general macroeconomic factors, could lead to increased costs, such as increased overtime to meet demand and increased wage rates to attract and retain employees, and could negatively affect our ability to efficiently operate and our overall business. If we are unable to hire and retain employees capable of performing at a high-level, or if mitigation measures we may take to respond to a decrease in labor availability, such as third-party outsourcing have unintended negative effects, our business could be adversely affected. An overall labor shortage, lack of skilled labor, increased turnover or labor inflation, caused by the COVID-19 endemic or as a result of general macroeconomic factors, could have a material adverse impact on our operations, results of operations, liquidity or cash flows.

You may experience future dilution as a result of future equity offerings or other equity issuances.

To raise additional capital, we may in the future offer additional shares of our common stock, preferred stock or other securities convertible into or exchangeable for our common stock. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share that you may have paid for any of such securities that you currently hold. The price per share at which we sell additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future transactions may be higher or lower than the price per share that you may have paid for previously for shares of our common stock. To the extent we raise additional capital by issuing equity securities or obtaining borrowings convertible into equity, ownership dilution to existing stockholders may result and future investors may be granted rights superior to those of existing stockholders.

Our outstanding options, warrants, convertible preferred shares, preferred investment option and the availability for resale of the underlying shares may adversely affect the trading price of our common stock.

As of December 31, 2023, we had outstanding stock options to purchase 14,000 shares of our common stock at a weighted-average exercise price of $501.70 per share and outstanding warrants to purchase up to an aggregate of 42 shares of common stock at a weighted-average exercise price of $3,360.00 per share.

We have registered with the SEC the resale by the holders of some of the shares of our common stock issuable upon exercise or conversion (as applicable) of our outstanding convertible instruments. The availability of these shares for public resale, as well as actual resales of these shares, could adversely affect the trading price of our common stock.

On July 27, 2022, at our 2022 Annual Meeting of Stockholders, the Company’s stockholders approved a proposal to authorize the Board, in its discretion but prior to July 26, 2023, to amend the Company’s Restated Certificate of Incorporation to effect a reverse stock split of all of the outstanding shares of the Company’s Common Stock, at a ratio in the range of 1-for-2 to 1-for-100, with such ratio to be determined by the Board, and all outstanding shares of Series D Preferred Stock were automatically redeemed. As a result, no shares of Series D Preferred Stock remain outstanding.

We cannot assure investors that our internal controls will prevent future material weaknesses.

Section 404 of the Sarbanes-Oxley Act requires, among other things, that we maintain effective internal controls for financial reporting and disclosure controls and procedures. We are required to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting. This assessment needs to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting.

There can be no assurance that we will not suffer from material weaknesses in the future. If we fail to remediate these material weaknesses or fail to otherwise maintain effective internal controls over financial reporting in the future, such failure could result in a material misstatement of our annual or quarterly consolidated financial statements that would not be prevented or detected on a timely basis and which could cause investors and other users to lose confidence in our consolidated financial statements, limit our ability to raise capital and have a negative effect on the trading price of our common stock. Additionally, failure to remediate the material weaknesses or otherwise failing to maintain effective internal controls over financial reporting may also negatively impact our operating results and financial condition, impair our ability to timely file our periodic and other reports with the SEC, subject us to additional litigation and regulatory actions and cause us to incur substantial additional costs in future periods relating to the implementation of remedial measures.

We are subject to legal actions that could adversely affect our financial condition.

From time to time, we may be involved in legal proceedings that arise in the ordinary course of business. Securities-related class action and derivative lawsuits have often been brought against companies, including many biotechnology companies, which experience volatility in the market price of their securities. This risk is especially relevant for biotechnology and biopharmaceutical companies such as ours, which often experience significant stock price volatility in connection with their product development programs.

We must pay the first legal fees and other litigation expenses incurred up to the application retention, or deductible, amounts under our insurance policies, including our director’s and officer’s and other liability insurance policies, and the insurance may not be sufficient to cover all of the liabilities that we may incur in connection with the pending or possible future legal actions. As a result, any future legal actions may adversely affect out financial condition.

Our anti-takeover measures may make it more difficult to change our management, or may discourage others from acquiring us, and thereby adversely affect stockholder value.

We have a stockholder rights plan and provisions in our amended and restated by-laws (the “Bylaws”), as amended, that are intended to protect our stockholders’ interests by encouraging anyone seeking control of our company to negotiate with our Board. These provisions may discourage or prevent a person or group from acquiring us without the approval of our Board, even if the acquisition would be beneficial to our stockholders.

We have a classified Board, which means that at least two stockholder meetings, instead of one, will be required to effect a change in the majority control of our Board. This applies to every election of directors, not just an election occurring after a change in control. The classification of our board increases the amount of time it takes to change majority control of our Board and may cause potential acquirers to lose interest in a potential purchase of us, regardless of whether our purchase would be beneficial to us or our stockholders. The additional time and cost to change a majority of the members of our board of directors makes it more difficult and may discourage our existing stockholders from seeking to change our existing management in order to change the strategic direction or operational performance of our company.

At the 2022 Annual Meeting of Stockholders, a proposal (the “Declassification Proposal”) to declassify the structure of the Board was passed on a precatory basis, which advised the Board that a majority of our stockholders desired to end the classified Board structure in favor of the annual election of directors, in which each director standing for election will only be eligible to be elected for one-year terms.

At the 2023 Annual Meeting of Stockholders, the Board adopted a resolution approving and declaring the advisability of amending our governing documents to the extent necessary to remove provisions that provided for a classified Board. This proposal provides for a rolling declassification of the Board to be completed by the 2026 annual meeting of the stockholders.

Our Bylaws provide that directors may only be removed for cause by the affirmative vote of the holders of at least a majority of the outstanding shares of our capital stock then entitled to vote at an election of directors. This provision prevents stockholders from removing any incumbent director without cause. Our Bylaws also provide that a stockholder must give us not fewer than 120 days but not more than 150 days’ notice of a proposal or director nomination that such stockholder desires to present at any annual meeting or special meeting of our stockholders. Such provision prevents a stockholder from making a proposal or director nomination at a stockholder meeting without us having advance notice of that proposal or director nomination. This could make a change in control more difficult by providing our directors with more time to prepare an opposition to a proposed change in control. By making it more difficult to remove or install new directors, these by-law provisions may also make our existing management less responsive to the views of our stockholders with respect to our operations and other issues such as management selection and management compensation.

We are subject to the anti-takeover provisions of Section 203 of the DGCL, which may also prevent or delay a takeover of us that may be beneficial to our stockholders.

Our Bylaws, as amended, designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or other employees.

Our Bylaws provide that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, or (iv) any action asserting a claim that is governed by the internal affairs doctrine. Any person purchasing or otherwise acquiring any interest in any shares of our capital stock shall be deemed to have notice of and to have consented to this provision of our Bylaws. This choice-of-forum provision may limit our stockholders’ ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits. Alternatively, if a court were to find this provision of our amended and restated by-laws inapplicable or unenforceable with respect to one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business and financial condition.

We may issue additional classes of preferred stock in the future, and the terms of the preferred stock may reduce the value of our common stock.

We are authorized to issue shares of preferred stock in one or more series. In the past, we have issued shares of preferred stock, including shares of our Preferred Stock issued in 2021. Our Board may determine the terms of future preferred stock offerings without further action by our stockholders. If we issue preferred stock, it could affect your rights or reduce the value of our outstanding common stock. In particular, specific rights granted to future holders of preferred stock may include voting rights, preferences as to dividends and liquidation, conversion and redemption rights, sinking fund provisions, and restrictions on our ability to merge with or sell our assets to a third party.

We do not expect to pay any cash dividends on our common stock.

We have not declared or paid any cash dividends on our common stock or other securities, and we currently do not anticipate paying any cash dividends in the foreseeable future. Because we do not anticipate paying cash dividends for the foreseeable future, our stockholders will not realize a return on their investment in our common stock except to the extent of any appreciation in the value of our common stock. Our common stock may not appreciate in value, or it may decline in value.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

Under Section 382 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes (such as research and development tax credits) to offset its post-change income and taxes may be limited. In general, an “ownership change” occurs if there is a cumulative change in our ownership by “5% shareholders” that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. As a result of a previous ownership change, our annual utilization of approximately $59.3 million in federal net operating loss carryforwards became substantially limited. If we experience ownership changes as a result of future transactions in our stock, we may be further limited in our ability to use our net operating loss carryforwards and other tax assets to reduce taxes owed on the net taxable income that we earn. Any such limitations on the ability to use our net operating loss carryforwards and other tax assets could potentially result in increased future tax liability to us on any net income that we may earn in the future.

Item 1B. UNRESOLVED STAFF COMMENTS

None.

Item 1C. CYBERSECURITY

Risk Management and Strategy

In an effort to protect our business against cybersecurity threats, we have implemented a cybersecurity risk management program that is integrated with our internal risk management processes and designed to identify and protect against cyber threats as well as to respond to and recover from cyber incidents, as applicable. Our cybersecurity risk management program is informed by industry standards, such as the National Institute of Standards and Technology (NIST) Cybersecurity Framework, and is supported by periodic internal and external information security assessments and testing.

We have also established incident response policies and procedures, overseen by our Chief Financial Officer, to review and classify cybersecurity incidents and to define roles and responsibilities for response and remediation in the event of a cyber incident.

In addition, we collaborate with third-party advisory firms to periodically review and evaluate our security measures, which informs our ongoing strategy and execution of our cybersecurity program. We also leverage third-party providers to augment our internal security resources, including to support our ongoing monitoring and threat detection capabilities. We have a process to evaluate certain critical third-party providers before engagement as well as periodically thereafter, which may include a review of available audit reports, security documentation, operating controls, and industry reputation, as well as contractual requirements, as appropriate.

We have not identified any cybersecurity incidents or threats that have materially affected us or are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition; however, like other companies in our industry, we and our third-party vendors have from time to time experienced threats and security incidents that could affect our information or systems. For more information, please see our Risk Factors.

Item 2. PROPERTIES

We lease our headquarters in Los Angeles, California. The lease covers approximately 2,771 square feet of office and storage space and expires in February 2024. We did not renew this lease. Our monthly rent is $15,361. We also lease additional storage space for approximately 540 square feet. This lease expired in February 2024, and requires us to make monthly payments of $1,475. The Company has signed a renewal for an 18-month term, at the same monthly payment. In March 2022, we entered into a sub-lease for our office space that provides for a monthly rental income of $8,867, subject to an annual increase of 3.5 percent. The sub-lease expires in February 2024.

Item 3. LEGAL PROCEEDINGS

We are occasionally involved in legal proceedings and other matters arising from the normal course of business. On November 30, 2022, Jerald Hammann (“Hammann”) filed a complaint (the “Complaint”) against the Company, Mr. Caloz, and Mr. Kriegsman (together, “Defendants”) in the Court of Chancery of the State of Delaware, alleging various violations of a Cooperation Agreement, dated August 21, 2020, by and between the Company and Hammann. The Complaint alleges breaches of a provision limiting the Board’s ability to effect discretionary compensation and a non-disparagement provision. The Complaint further alleges a breach of a purported implied obligation that the Company disclose various internal records to Hammann. Defendants believe the Complaint is wholly without merit and have moved to dismiss the Complaint in its entirety. Defendants intend to litigate vigorously against Hammann’s claims.

We intend to vigorously defend against any complaint. We have directors’ and officers’ liability insurance, which will be utilized, after the deductible, in the defense of any matter involving our directors or officers.

We evaluate developments in legal proceedings and other matters on a quarterly basis. If an unfavorable outcome becomes probable and reasonably estimable, we could incur charges that could have a material adverse impact on our financial condition and results of operations for the period in which the outcome becomes probable and reasonably estimable.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read together with the discussion under “Selected Financial Data” and our consolidated financial statements included in this Annual Report. This discussion contains forward-looking statements, based on current expectations and related to future events and our future financial performance, that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many important factors, including those set forth under the caption “Risk Factors” and elsewhere in this Annual Report.

Overview

LadRx Corporation is a biopharmaceutical research and development company specializing in oncology. The Company’s focus is on the discovery, research and clinical development of novel anti-cancer drug candidates that employ novel technologies that target chemotherapeutic drugs to solid tumors and reduce off-target toxicities. During 2017, LadRx’s discovery laboratory in Freiburg, Germany, synthesized and tested over 75 rationally designed drug conjugates with highly potent anti-cancer payloads, culminating in the creation of two distinct classes of compounds. Four lead candidates (LADR 7 through LADR-10) were selected based on in vitro and animal studies in several different cancer models, stability, and manufacturing feasibility. In addition, a novel companion diagnostic, ACDx™, was developed to identify patients with cancer who are most likely to benefit from treatment with these drug candidates.

On June 1, 2018, the Company launched Centurion BioPharma Corporation (“Centurion”), a wholly-owned private subsidiary, and transferred to Centurion all of its assets, liabilities and personnel associated with the laboratory operations in Freiburg, Germany. In connection with said transfer, the Company and Centurion entered into a Management Services Agreement whereby the Company agreed to render advisory, consulting, financial and administrative services to Centurion, for which Centurion shall reimburse the Company for the cost of such services plus a 5% service charge. On December 21, 2018, LadRx announced that Centurion had concluded the pre-clinical phase of development for its four LADR™ (Linker Activated Drug Release) drug candidates, and for its albumin companion diagnostic (ACDx™). As a result of completing this work, operations taking place at the pre-clinical laboratory in Freiburg, Germany were no longer needed and, accordingly, the lab was closed at the end of January 2019.

On March 9, 2022, Centurion merged with and into LadRx, with LadRx absorbing all of Centurion’s assets and continuing after the merger as the surviving entity (the “Merger”). The Merger was implemented through an agreement and plan of merger pursuant to Section 253 of the General Corporation Law of the State of Delaware (the “DGCL”) and did not require approval from either our or Centurion’s stockholders. The Certificate of Ownership merging Centurion into LadRx was filed with the Secretary of State of Delaware on March 9, 2022.

Effective September 26, 2022, the Company changed its name from CytRx Corporation to LadRx Corporation pursuant to a Certificate of Amendment to our Restated Certificate of Incorporation (the “Certificate of Incorporation”) filed with the Secretary of State of Delaware. In accordance with the DGCL, its board of directors (the “Board”) approved the name change and the Certificate of Amendment. Pursuant to Section 242(b)(1) of the DGCL, stockholder approval was not required for the name change or the Certificate of Amendment.

2023 Reverse Stock Split

The Company effected a 1-for-100 reverse stock split (the “Reverse Stock Split”) of its issued and outstanding shares of common stock on May 17, 2023, pursuant to which every 100 shares of the Company’s issued and outstanding shares of common stock were converted into one share of common stock without any change in the par value per share. Any fraction of a share of common stock that would otherwise have resulted from the Reverse Stock Split were rounded up to the nearest whole share. All share and per share amounts in this Annual Report have been adjusted to reflect the reverse stock split as if it had occurred at the beginning of the earliest period presented.

LADR Drug Discovery Platform

The LADR™ Technology offers the opportunity for multiple pipeline drugs. The Company’s LADR™ technology platform consists of an organic backbone that is attached to a chemotoxic agent. The purpose of the LADR™ backbone is to first target and deliver the chemotoxic agent to the tumor environment, and then to release the chemotoxic agent within the tumor. By delivering, concentrating, and releasing the chemotoxic agent within the tumor, one expects to reduce the off-target side-effects of the chemotherapeutic, which in turn allows for several-fold higher dosing of the chemotherapeutic to the patient. Being small organic molecules, the Company expects LADR-based drugs to offer the benefits of targeting the tumor without the complexity, side effects, and expense inherent in macromolecules such as antibodies and nanoparticles.

The Company’s LADR-based drugs use circulating albumin as the binding target and as the trojan horse to deliver the LADR™ drugs to the tumor. Albumin is the most abundant protein in plasma and accumulates inside tumors due to the aberrant vascular structure that exists within solid tumors. Tumors use albumin as a nutritional source and for transport of signaling and other molecules that are important to the maintenance and growth of the tumor, which makes albumin an excellent target for drugs that are intended for solid tumors.

The Company’s LADR™ development efforts are focused on two classes of ultra-high potency albumin-binding drugs. These LADR-based drugs, LADRs 7, 8, 9, and 10, combine the proprietary LADR™ backbone with novel derivatives of the auristatin and maytansinoid drug classes. Auristatin and maytansinoid are highly potent chemotoxins, and require targeting to the tumor for safe administration to humans, as is the case for the U.S. Food and Drug Administration (“FDA”)-approved drugs Adcetris (auristatin antibody-drug-conjugate manufactured by Seagen, Inc.) and Kadcyla (maytansine antibody-drug-conjugate manufactured by Genentech, Inc.). We believe that LADR-based drugs offer the benefits of tumor targeting without the disadvantages of antibodies and other macromolecules, which include expense, complexity, and negative side effects. Additionally, albumin is a very well-characterized drug target, which we believe will reduce clinical and regulatory costs and risks.

The Company’s postulated mechanism of action for LADR-based drugs is as follows:

The first-generation LADR-based drug is called Aldoxorubicin. Aldoxorubicin is the well-known drug doxorubicin attached to the first generation LADR™ backbone (LADRs 7-10 employ a next generation LADR™ backbone). Aldoxorubicin has been administered to over 600 human subjects in human clinical trials and has proven the concept of LADR™ in that several-fold more doxorubicin can be safely administered to patients when the doxorubicin is attached to LADR™ than when administered as native doxorubicin. Aldoxorubicin has been licensed to ImmunityBio and is currently in a Phase II trial for pancreatic cancer.

The next generation LADR™ drugs are termed LADR 7, 8, 9, and 10. A great deal of Investigational New Drug (“IND”) enabling work has already been accomplished on LADR 7-10, including in-silico modeling, in-vitro efficacy testing in several different cancer models, in-vivo dosing, safety, and efficacy testing in several different cancer models in animals. We have also developed and proven manufacturability, an important step prior to beginning human clinical trials.

The IND-enabling work that remains prior to applying to the FDA for first-in-human studies for LADR 7-10 is limited due to the extensive experimentation already completed. For example, in the case of LADR 7, a manufacturing run under Good Manufacturing Practices (GMP) has been completed and the GMP LADR 7 currently in hand is sufficient to carry out final toxicology studies, and to initiate Phase IA studies in humans.

We expect the toxicology studies to be completed and the IND application for LADR 7 to be filed with the FDA by the end of the third quarter of 2024 or the beginning of the fourth quarter of 2024. Absent a clinical hold from the FDA, this timeline should allow the Company to be ready for first-patient dosing with LADR 7 by the end of 2024 (the period for the FDA review of an IND application is 30 days). If the Company encounters difficulties with the toxicology program or fails to meet the FDA’s requirements for the IND application, the first-patient dosing could be substantially delayed.

Because the LADR™ backbone in future products would be the same as the LADR™ backbone in current product candidates, (i.e. the chemotoxin can be changed without changing the LADR™ backbone), management anticipates that future product candidates beyond LADR 7-10 may enjoy abbreviated pre-clinical pathways to first-in-human. Such abbreviated pathways would be subject to FDA review and agreement.

The Company’s novel companion diagnostic, ACDx™ (albumin companion diagnostic) was developed to identify patients with cancer who are most likely to benefit from treatment with the four LADR™ lead assets. We have not yet determined whether the use of a companion diagnostic will be necessary or helpful, and plan to continue to investigate this question in parallel to the pre-clinical and clinical development of LADRs 7-10.

The LADR™ backbone and drugs that employ LADR™ are protected by domestic and international patents, and additional patents are pending.

Business Strategy for LADR™ Platform

With the non-dilutive financing concluded with XOMA (as defined below) in June 2023, the Company is now focused on preparing the work necessary to file an IND application with the FDA for LADR7. For example, the Company recently completed the production of approximately 100 grams of LADR7 under GMP, which is sufficient to carry out final toxicology studies, and to initiate Phase IA studies in human subjects.

The Company has also initiated the Good Laboratory Practices (“GLP”) toxicology program that is expected to form the foundation of the IND application for LADR 7 to the FDA. Management expects the toxicology studies to be completed and the IND application for LADR 7 to be filed with the FDA by the end of the third quarter of 2024 or the beginning of the fourth quarter of 2024. Absent a clinical hold from the FDA, this timeline should allow the Company to be ready for first-patient dosing with LADR 7 by the end of 2024 (the period for the FDA review of an IND application is 30 days). If the Company encounters difficulties with the toxicology program or fails to meet the FDA’s requirements for the IND, the first-patient dosing could be substantially delayed.

Management will continue to explore in parallel both partnered and non-partnered funding and development strategies for LADR™ with a goal of obtaining the least costly capital possible to enable value inflection milestones.

Partnering of Aldoxorubicin

On July 27, 2017, the Company entered into an exclusive worldwide license (the “2017 License Agreement”) with ImmunityBio, Inc. (formerly known as NantCell, Inc., and which merged with NantKwest Inc. in March 2021 (“ImmunityBio”)), granting to ImmunityBio the exclusive rights to develop, manufacture and commercialize aldoxorubicin in all indications. As a result, we are no longer directly working on the development of aldoxorubicin. As part of the 2017 License Agreement, ImmunityBio made a strategic investment of $13 million in LadRx’s common stock at $660.00 per share (adjusted to reflect our reverse stock splits), a premium of 92% to the market price on that date. The Company also issued a warrant to ImmunityBio to purchase up to 5,000 shares of common stock at $660.00 per share, which such warrant expired on January 26, 2019.

ImmunityBio is conducting an open-label, randomized, Phase 2 study of a combination of immunotherapy, aldoxorubicin, and standard-of-care chemotherapy versus standard-of-care chemotherapy alone for the treatment of locally advanced or metastatic pancreatic cancer in patients who have had 1 or 2 lines of treatment (Cohorts A and B) or 3 or greater lines of treatment (cohort C). In June 2022, Immunity Bio presented data at the American Society of Clinical Oncology meeting showing that patients receiving combination immunotherapy with aldoxorubicin plus standard-of-care chemotherapy experienced overall survival of 5.8 months, compared to 3 months for historical control patients that had received only the standard-of-care chemotherapy (n=78, 95% confidence interval of 4 to 6.9 months). An additional 25 patients in the experimental group remain in the study. As of the date of this Annual Report, there have been no treatment-related deaths, and serious adverse events have been uncommon (6%).

Aldoxorubicin has received Orphan Drug Designation (“ODD”) by the FDA for the treatment of soft tissue sarcoma (“STS”). ODD provides several benefits including seven years of market exclusivity after approval, certain R&D related tax credits, and protocol assistance by the FDA. European regulators granted aldoxorubicin Orphan designation for STS which confers ten years of market exclusivity among other benefits.

Royalty Purchase Agreement with XOMA

On June 21, 2023, the Company, entered into (i) a Royalty Purchase Agreement (the “Royalty Agreement”) with XOMA (US) LLC (“XOMA”), for the sale, transfer, assignment and conveyance of the Company’s right, title and interest in and to certain royalty payments and milestone payments with respect to aldoxorubicin, and (ii) an Assignment and Assumption Agreement (the “Assignment Agreement”) with XOMA for the sale, transfer, assignment and conveyance of the Company’s right, title and interest in the Asset Purchase Agreement (the “2011 Arimoclomol Agreement”) between the Company and Orphazyme ApS (“Orphazyme”), dated as of May 13, 2011, and assigned to Zevra Denmark A/S (“Zevra Denmark”), effective as of June 1, 2022, which includes certain royalty and milestone payments with respect to arimoclomol. The combined aggregate purchase price paid to the Company for the sale, transfer, assignment and conveyance of the Company’s right, title and interest in and to aldoxorubicin and arimoclomol was $5 million, less certain transaction fees and expenses.

The Royalty Agreement and the Assignment Agreement also provide for up to an additional $6 million based on regulatory and commercial milestones related to the development of arimoclomol and aldoxorubicin by their respective sponsors, Zevra, Inc. and Immunity Bio, Inc. The $6 million in potential post-closing payments is comprised of $1 million upon acceptance by the FDA of the arimoclomol New Drug Application (“NDA”), $1 million upon first commercial sale of arimoclomol, and $4 million upon FDA approval of aldoxorubicin. All royalty and milestone payments made to XOMA will be net of the existing licensing and milestone obligations owed by LadRx related to arimoclomol and aldoxorubicin.

Pursuant to the Royalty Agreement, the Company agreed to sell, transfer, assign and convey to XOMA, among other payments, all royalty payments and regulatory and commercial milestone payments payable to the Company pursuant to the worldwide license agreement, dated July 27, 2017, by and between the Company and Immunity Bio, Inc.. The Royalty Agreement also provides for the sharing of certain rights with XOMA to bring any action, demand, proceeding or claim as related to receiving such payments.

Management determined that the Royalty Agreement is not considered to be with a customer, and it does not fall within the scope of ASC 606. Instead, the Royalty Agreement represents an in-substance sale of nonfinancial assets, and, therefore, should be accounted for within the scope of ASC 610-20. As such, the Company recognized such net proceeds as other income in the accompanying statement of operations.

Transfer of Rights to Molecular Chaperone Assets (Orphayzme)

On May 13, 2011, pursuant to the Asset Purchase Agreement by and between the Company and Orphazyme A/S (“Orphazyme”, formerly Orphazyme ApS), LadRx sold the rights to arimoclomol and iroxanadine, based on molecular chaperone regulation technology, in exchange for a one-time, upfront payment and the right to receive up to a total of $120 million in milestone payments upon the achievement of certain pre-specified regulatory and business milestones, as well as royalty payments based on a specified percentage of any net sales of products derived from arimoclomol (the “2011 Arimoclomol Agreement”). Orphazyme transferred its rights and obligations under the 2011 Arimoclomol Agreement to KemPharm Denmark A/S (“KemPharm”), a wholly owned subsidiary of KemPharm Inc., in May 2022.

In May 2021, Orphazyme announced that the pivotal phase 3 clinical trial for arimoclomol in Amyotrophic Lateral Sclerosis did not meet its primary and secondary endpoints, reducing the maximum amount that LadRx currently has the right to receive under the 2011 Arimoclomol Agreement to approximately $100 million. Orphazyme also tested arimoclomol in Niemann-Pick disease Type C (“NPC”) and Gaucher disease, and following a Phase II/III trial submitted to the FDA a New Drug Application for the treatment of NPC with arimoclomol. On June 18, 2021, Orphazyme announced it had received a complete response letter (the “Complete Response Letter”) from the FDA indicating the need for additional data. In late October 2021, Orphazyme announced it held a Type A meeting with the FDA, at which the FDA recommended that Orphazyme submit additional data, information and analyses to address certain topics in the Complete Response Letter and engage in further interactions with the FDA to identify a pathway to resubmission. The FDA concurred with Orphazyme’s proposal to remove the cognition domain from the NPC Clinical Severity Scale (“NPCCSS”) endpoint, with the result that the primary endpoint is permitted to be recalculated using the 4- domain NPCCSS, subject to the submission of additional requested information which Orphazyme had publicly indicated that it intended to provide. To bolster the confirmatory evidence already submitted, the FDA affirmed that it would require additional in vivo or pharmacodynamic (PD)/pharmacokinetic (PK) data.

Orphazyme had also submitted a Marketing Authorization Application (“MAA”) with the European Medicines Agency (the “EMA”). In February 2022, Orphazyme announced that although they had received positive feedback from the Committee for Medicinal Products for Human Use (“CHMP”) of the EMA, they were notified by the CHMP of a negative trend vote on the MAA for arimoclomol for NPC following an oral explanation.

On May 31, 2022, Orphazyme announced that it had completed the sale of substantially all of its assets and business activities for cash consideration of $12.8 million and assumption of liabilities estimated to equal approximately $5.2 million to KemPharm (the “KemPharm Transaction”). KemPharm is a specialty biopharmaceutical company focused on the discovery and development of novel treatments for rare CNS diseases. As part of the KemPharm Transaction, all of Orphazyme’s obligations to LadRx under the 2011 Arimoclomol Agreement, including with regard to milestone payments and royalties on sales, were assumed by KemPharm. KemPharm is expected to continue the early access programs with arimoclomol, and to continue to pursue the potential approval of arimoclomol as a treatment option for NPC. KemPharm resubmitted the NDA for arimoclomol in 2023. It is also identifying a regulatory path forward with the EMA. KemPharm re-branded to Zevra Therapeutics, Inc. in February 2023.

Assignment and Assumption Agreement with XOMA

On June 21, 2023, the Company entered into the Assignment Agreement with XOMA, pursuant to which, among others, the Company agreed to sell, transfer and assign to XOMA the Company’s right, title and interest in the arimoclomol pursuant to the 2011 Arimoclomol Agreement, including the right to receive certain milestone, royalty and other payments from Zevra.

Pursuant to the Assignment Agreement, the Company is entitled to receive (i) a one-time payment of $1 million upon acceptance of a re-submission of a New Drug Application to the FDA for arimoclomol, and (ii) a one-time payment of $1 million upon the first invoiced sale in certain territories of a pharmaceutical product derived from arimoclomol as an active pharmaceutical ingredient, subject to the receipt of the applicable regulatory approval required to sell such a product in such countries. In January 2024, Zevra announced the FDA had accepted the NDA for arimoclomol and the Company received the one-time payment of $1 million in February 2024.

Research and Development

In 2023, the Company spent $280,000 on expenditures for research and development activities related to continuing operations; there were no such expenditures in 2022.

The Company is continuing to conduct activities with the goal of filing an IND application for LADR7 towards the end of 2024.

All of our product candidates in development must be approved by the FDA or corresponding foreign governmental agencies before they can be marketed. The process for obtaining FDA and foreign government approvals is both time-consuming and costly, with no certainty of a successful outcome. A discussion of these and other risks and uncertainties associated with our business is set forth in the “Risk Factors” section of this Annual Report.

Research and Development Expenses

Research and development expenses consist of costs incurred for direct and overhead-related research expenses and are expensed as incurred. Costs to acquire technologies, including licenses, that are utilized in research and development and that have no alternative future use are expensed when incurred. Technology developed for use in our product candidates is expensed as incurred until technological feasibility has been established.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates its estimates, including those related to stock options, impairment of long-lived assets, including accrued liabilities and certain expenses. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions.

Our significant accounting policies are summarized in Note 2 of the Notes to Consolidated Financial Statements included in this Annual Report. We believe the following critical accounting policies are affected by our more significant judgments and estimates used in the preparation of our consolidated financial statements:

Clinical Trial Expenses

Clinical trial expenses, which are included in research and development expenses, include obligations resulting from our contracts with various contract research organizations (“CROs”), in connection with conducting clinical trials of our product candidates. We recognize expenses for these activities based on a variety of factors, including actual and estimated labor hours, clinical site initiation activities, patient enrollment rates, estimates of external costs and other activity-based factors. We believe that this method is the best measure of the efforts expended on a clinical trial with the expenses we record. We adjust our rate of clinical expense recognition if actual results differ from our estimates. If our estimates prove to be incorrect, clinical trial expenses recorded in any particular period could vary.

Stock-based Compensation

The fair value of the Company’s stock option and restricted stock grants is estimated using the Black-Scholes-Merton Option Pricing model, which uses certain assumptions related to risk-free interest rates, expected volatility, expected life of the stock options or restricted stock, and future dividends. Compensation expense is recorded based upon the value derived from the Black-Scholes-Merton Option Pricing model and based on actual experience. The assumptions used in the Black-Scholes-Merton Option Pricing model could materially affect compensation expense recorded in future periods.

Basic and Diluted Net Income (Loss) Per Share of Common Stock

Basic and diluted net income (loss) per share of common stock is computed based on the weighted-average number of shares of common stock outstanding. for the period. Diluted net income (loss) per share is computed by dividing the net income (loss) applicable to common stockholders by the weighted average number of shares of common stock outstanding plus the number of additional shares of common stock that would have been outstanding if all dilutive potential common stock had been issued using the treasury stock method. Potential shares of common stock are excluded from the computation when their effect is antidilutive. Common stock equivalents that could potentially dilute net income (loss) per share in the future, and which were excluded from the computation of diluted income (loss) per share, were as follows:

Liquidity and Capital Resources

Going Concern

The Company’s consolidated financial statements have been presented on the basis that it will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. During the year ended December 31, 2023, although we realized a net income of $0.4 million, we had a loss from operations of $3.8 million, and incurred a net loss of $4.2 million for the year ended December 31, 2022, and had total stockholders’ equity as of December 31, 2023 of $0.1 million. The Company has no recurring revenue, and we are likely to continue to incur losses unless and until we conclude a successful strategic partnership or financing for our LADR™ technology. As a result, management has concluded that there is substantial doubt about the Company’s ability to continue as a going concern. The Company’s consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

In order to fund our business and operations, we have relied primarily upon sales of our equity securities, including proceeds from the exercise of stock options and common stock purchase warrants and long-term loan financing. We also have received limited funding from our strategic partners and licensees. We will ultimately be required to obtain additional funding in order to execute our long-term business plans, although we do not currently have commitments from any third parties to provide us with long-term debt or capital. We cannot assure that additional funding will be available on favorable terms, or at all. If we fail to obtain additional funding when needed, we may not be able to execute our business plans and our business may suffer, which would have a material adverse effect on our financial position, results of operations and cash flows. We have approximately $1.0 million of contractual obligations in 2024 and expect to pay these out of the Company’s balance sheet cash. We have a total of approximately $1.0 million in material contractual obligations beyond 2024.

We have no commitments from third parties to provide us with any additional financing, and we may not be able to obtain future financing on favorable terms, or at all. Failure to obtain adequate financing would adversely affect our ability to operate as a going concern. If we raise additional funds by issuing equity securities, dilution to stockholders may result and new investors could have rights superior to some or all of our existing equity holders. In addition, debt financing, if available, may include restrictive covenants. If adequate funds are not available to us, we may have to liquidate some or all of our assets or to delay or reduce the scope of or eliminate some portion or all of our development programs or clinical trials.

Discussion of Operating, Investing and Financing Activities

Cash Flows from Operating Activities

Net cash provided in operating activities for the year ended December 31, 2023 was $1.0 million, which was primarily the result of the sale of royalty and milestone rights, net of transaction costs of $4.2 million less a net loss from operations of $3.8 million, plus $0.6 million in net cash outflows associated with changes in assets and liabilities. The net cash outflows associated with changes in assets and liabilities were primarily due to reductions of $0.4 million of prepaid expenses and $0.2 million in amortization of right-of-use assets, an increase of $0.2 million in accounts payable, offset by a decrease in lease liabilities of $0.2 million.

Net cash used in operating activities for the year ended December 31, 2022 was $4.8 million, which was primarily the result of a net loss from operations of $4.2 million, plus $0.6 million in net cash outflows associated with changes in assets and liabilities. The net cash outflows associated with changes in assets and liabilities were primarily due to reductions of $1.0 million of accrued expenses, $0.5 million in accounts payable and $0.2 million in lease liabilities, offset by an increase in prepaid expenses and other current assets of $0.7 million, $0.2 million in insurance receivable and $0.2 million in amortization of right-of-use assets.

Cash Flows from Investing Activities

We purchased minimal fixed assets in both the years ended December 31, 2023 and December 31, 2022 and do not expect any significant capital spending during the next 12 months.

Cash Flows from Financing Activities

We purchased the preferred investment options for $250,000 and paid dividends of $69,000 on the shares of Series C Preferred Stock in the year ended December 31, 2023.

We paid dividends of $0.6 million on the shares of Series C Preferred Stock in the year ended December 31, 2022.

We continue to evaluate potential future sources of capital, as we do not currently have commitments from any third parties to provide us with additional capital and we may not be able to obtain future financing on favorable terms, or at all. The results of our technology licensing efforts and the actual proceeds of any fund-raising activities will determine our ongoing ability to operate as a going concern. Our ability to obtain future financings through joint ventures, product licensing arrangements, royalty sales, equity financings, grants or otherwise is subject to market conditions and our ability to identify parties that are willing and able to enter into such arrangements on terms that are satisfactory to us. Depending upon the outcome of our fundraising efforts, the accompanying financial information may not necessarily be indicative of our future financial condition. Failure to obtain adequate financing would adversely affect our ability to operate as a going concern.

There can be no assurance that we will be able to generate revenues from our product candidates and become profitable. Even if we become profitable, we may not be able to sustain that profitability.

We do not have any off-balance sheet arrangements.

Results of Operations

We incurred a net income (loss) of $0.4 million and ($4.2) million for the years ended December 31, 2023 and 2022, respectively.

During the years ended December 31, 2023 and 2022, we recognized no service revenue and earned an immaterial amount of license fees and grant revenue. We will no longer be entitled to future licensing revenues from our current licensing agreements, since we transferred the royalty and milestone rights associated with arimoclomol and aldoxorubicin to XOMA, pursuant to the Royalty Agreement and the Assignment Agreement for net proceeds of approximately $4.2 million, along with an aggregate of $6 million in potential post-closing payments, based on achievement of certain future milestones. We recognized the net proceeds in connection with the Royalty Agreement and the Assignment Agreement as Other Income on our consolidated statement of operations.

General and Administrative

General and administrative expenses include all administrative salaries and general corporate expenses, including legal expenses associated with the prosecution of our intellectual property. Our general and administrative expenses, excluding employee stock and stock option exercises, were $3.5 million and $4.5 million in the years ended December 31, 2023 and 2022, respectively.

Research and Development

Research expenses are expenses incurred by us in the discovery of new information that will assist us in the creation and the development of new drugs or treatments. Development expenses are expenses incurred by us in our efforts to commercialize the findings generated through our research efforts.

We incurred $0.3 million in research and development expenses in the year ended December 31, 2023, as compared to $0 in the comparative 2022 year.

Depreciation and Amortization

Depreciation and amortization expenses for the years ended December 31, 2023 and 2022 were approximately $12,000 and $15,000, respectively. The depreciation expense reflects the depreciation of our equipment and furnishings.

Interest Income

Interest income was $55,000 in the year ended December 31, 2023 and $12,000 in the year ended December 31, 2022. The variance between years is attributable primarily to the amount of funds available for investment each year and, to a lesser extent, changes in prevailing market interest rates.

Known Trends, Events and Uncertainties

Not applicable

Recently Adopted Accounting Pronouncements

Recent authoritative guidance issued by the FASB (including technical corrections to the ASC), the American Institute of Certified Public Accountants, and the SEC did not, or are not expected to, have a material impact on the Company’s consolidated financial statements and related disclosures.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Historically, our exposure to market risk is limited primarily to interest income sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because a significant portion of our investments are in short-term debt securities issued by the U.S. government and institutional money market funds. The primary objective of our investment activities is to preserve principal. Due to the short-term nature of our investments, we believe that we are not exposed to any material market risk. We do not have any speculative or hedging derivative financial instruments or foreign currency instruments. If interest rates had varied by 10% in the year ended December 31, 2023, it would not have had a material effect on our results of operations or cash flows for that period.

Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Our consolidated financial statements and notes thereto as of December 31, 2023 and 2022, and for the years ended December 31, 2023 and 2022, together with the reports thereon of our independent registered public accounting firm, are set forth beginning on page F-1 of this Annual Report.

Based on this evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of December 31, 2023, as described further below.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we assessed the effectiveness of our internal control over financial reporting as of December 31, 2023. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework (2013 Edition). Based upon management’s assessment using the criteria contained in COSO, management has concluded that our internal control over financial reporting was effective as of December 31, 2023.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the year ended December 31, 2022 that have materially affected, or are reasonably likely to have a material affect, on our internal control over financial reporting.

Family Relationships

There are no family relationships among our directors and executive officers.

Involvement in Certain Legal Proceedings

None of our directors or executive officers has been involved in any of the following events during the past ten years:

Diversity

Our Board is responsible for assembling for stockholder consideration director-nominees who, taken together, have appropriate experience, qualifications, attributes, and skills to function effectively as a board. The Board periodically reviews its composition in light of our changing requirements, its assessment of its performance, and the input of stockholders and other key constituencies. The Board looks for certain characteristics common to all board members, including integrity, strong professional reputation and record of achievement, constructive and collegial personal attributes, and the ability and commitment to devote sufficient time and energy to board service. In addition, they seek to include on the Board a complementary mix of individuals with diverse backgrounds and skills reflecting the broad set of challenges that the Board confronts. These individual qualities can include matters such as experience in our company’s industry, technical experience (i.e., medical or research expertise), experience gained in situations comparable to the company’s, leadership experience, and relevant geographical diversity.

Corporate Governance

Board Committees, Meetings and Attendance

Our business, property and affairs are managed by or under the direction of the board of directors. Members of the board are kept informed of our business through informal discussions with our chief executive and financial officers and other officers, by reviewing materials provided to them and by participating at meetings of the board and its committees.

Our Board currently has two committees, the Audit Committee, in accordance with section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Securities Act”), and the Compensation Committee. The Audit Committee consists of Mr. Caldwell and Mr. Claiborne. The Chairman of the Audit Committee is Mr. Caldwell. The Compensation Committee consists of Mr. Claiborne and Dr. Simpson. Mr. Claiborne is the Chairman of the Compensation Committee. The Audit Committee and the Compensation Committee operate under formal charters that govern their duties and conduct. Copies of the charters are available on our website at www.ladrx.com.

Our Board has determined that Mr. Caldwell, one of the independent directors serving on our Audit Committee, is an “audit committee financial expert” as defined by the SEC’s rules. Our Board has determined that Mr. Claiborne and Mr. Caldwell are “independent” under the current independence standards of both The OTC Market and the SEC.

In the year ended December 31, 2023, the Board met five times, the Audit Committee met four times and the Compensation Committee met once.

Section 16(a) Beneficial Ownership Reporting Compliance

Delinquent Section 16(a) Reports

Each of our executive officers and directors and persons who own more than 10% of our outstanding shares of common stock is required under Section 16(a) of the Exchange Act to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and to furnish us with copies of those reports. To our knowledge, based solely on our review of copies of reports we have received and written representations from certain reporting persons, we do not believe that there were any delinquent filers. We believe our directors and executive officers and greater than 10% shareholders for the year ended December 31, 2023 complied with all applicable Section 16(a) filing requirements.

Code of Ethics

We have adopted a Code of Ethics applicable to all employees, including our principal executive officer, principal financial officer and principal accounting officer, a copy of which is available on our website at www.ladrx.com. We will furnish, without charge, a copy of our Code of Ethics upon request. Such requests should be directed to Attention: Corporate Secretary, 11726 San Vicente Boulevard, Suite 650, Los Angeles, California, or by telephone at 310-826-5648.

Insider Trading Policy

We have adopted an insider trading policy governing the purchase, sale, and/or other dispositions of our securities by our directors, officers and employees. The insider trading policy is designed to promote compliance with insider trading laws, rules and regulations.

Board Structure

Our Certificate of Incorporation and our Bylaws previously provided for the classification of our directors into three classes, which we refer to as Class I, Class II and Class III, with each class to consist as nearly as possible of an equal number of directors.

At the 2022 Annual Meeting, a Declassification Proposal to declassify the structure of the Board was passed on a precatory basis, which advised the Board that a majority of our stockholders desired to end the classified Board structure in favor of the annual election of directors, in which each director standing for election will only be eligible to be elected for one-year terms. At the 2023 Annual Meeting, the stockholders approved the Board’s adoption of a resolution approving and declaring the advisability of amending our governing documents to the extent necessary to remove provisions that provide for a classified Board. This resolution provided for a rolling declassification of the Board to be completed by the 2026 annual meeting of the stockholders.

On September 8, 2023, we filed a Certificate of Amendment of Restated Certificate of Incorporation (the “Certificate of Amendment”) with the Secretary of State of Delaware to amend and restate in its entirety Section 2 of Article Eighth of our Restated Certificate of Incorporation to effect the declassification of our Board as approved by our stockholders. Our board also amended certain provisions of our Amended and Restated By-Laws (the “By-Laws”) consistent with the Certificate of Amendment. Following the filing of the Certificate of Amendment and the amendment of our By-Laws, our Class I director will serve until the 2025 annual meeting of our stockholders, our Class II director will serve until the 2024 annual meeting of our stockholders, and our Class III director will serve until the 2026 annual meeting of our stockholders.

Board of Directors Role in Risk Oversight

In connection with its oversight responsibilities, our Board, including the Audit Committee, periodically assesses the significant risks that we face. These risks include, but are not limited to, financial, technological, competitive, and operational risks. Our Board administers its risk oversight responsibilities through our Chief Executive Officer and Chief Financial Officer who review and assess the operations of our business, as well as operating management’s identification, assessment and mitigation of the material risks affecting our operations.

The 2008 Plan expired on November 20, 2018, and thus no shares are available for future grant under the 2008 Plan.

Awards under the 2019 Plan

The following is a summary description of financial instruments that may be granted to participants in our 2019 Plan by the Compensation Committee of our Board.

Stock Options. The Compensation Committee is authorized to grant non-qualified stock options. The terms of any incentive stock option must meet the requirements of Section 422 of the Internal Revenue Code.

Limitations on Transfer; Beneficiaries. Stock Option awards under the 2019 Plan may generally not be transferred or assigned by participants other than by will or the laws of descent and distribution.

Acceleration Upon Certain Events. In the event of a “Corporate Transaction” as defined in the 2019 Plan, all outstanding options will become fully vested, subject to the holder’s consent with respect to incentive stock options, and exercisable and all restrictions on all outstanding awards will lapse. Unless the surviving or acquiring entity assumes the awards in the Corporate Transaction or the stock award agreement provides otherwise, the stock awards will terminate if not exercised at or prior to the Corporate Transaction.

Termination and Amendment

Our Board or the Compensation Committee may, at any time and from time to time, terminate or amend the 2019 Plan without stockholder approval; provided, however, that our Board or the Compensation Committee may condition any amendment on the approval of our stockholders if such approval is necessary or deemed advisable with respect to tax, securities or other applicable laws, policies or regulations. No termination or amendment of the Plans may adversely affect any award previously granted without the written consent of the participants affected. The Compensation Committee may amend any outstanding award without the approval of the participants affected, except that no such amendment may diminish or impair the value of an award.

In the event Mr. Caloz’s employment is terminated due to disability or death, all of Mr. Caloz’s unvested stock options and other equity awards based on the Company’s securities will immediately vest in full and all of Mr. Caloz’s stock options and any other equity awards will remain exercisable for their full term notwithstanding the termination of his employment.

Compensation of Directors

We use a combination of cash and stock-based compensation to attract and retain qualified candidates to serve on our Board. Directors who also are employees of our company currently receive no compensation for their service as directors or as members of board committees. In setting director compensation, we consider the significant amount of time that directors dedicate to the fulfillment of their director responsibilities, as well as the competency and skills required of members of our board. The directors’ annual compensation year begins with the annual election of directors at the annual meeting of stockholders. Periodically, our Board reviews our director compensation policies and, from time to time, makes changes to such policies based on various criteria the board deems relevant. For 2023, the Board implemented an increase of 4 percent in their compensation.

The non-employee director who serves as Chair of the Board receives a quarterly retainer of $6,500. Our non-employee directors receive a quarterly retainer of $6,240 (plus an additional $5,200 for the Chairmen of the Audit and Compensation Committees), a fee of $4,160 for each Board meeting attended ( or $750 for Board actions taken by unanimous written consent) and $3,120 for each meeting of the Audit Committee and $2,600 for each meeting of the Compensation Committee attended. Non-employee directors who serve as the chairman of a board committee receive an additional $3,120 for each Audit Committee meeting they chair and an additional $4,160 for each Compensation Committee meeting they chair and the non-employee director who serves as chairperson of the Board receives an additional $4,160 for each meeting attended.

The following table sets forth the compensation paid to our directors other than our Chief Executive Officer for 2023:

Director Compensation Table

Item 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

Based solely upon information made available to us, the following table sets forth information with respect to the beneficial ownership of our common stock as of March 27, 2024 by (1) each person who is known by us to beneficially own more than five percent of our common stock; (2) each of our directors; (3) the Named Executive Officers listed in the Summary Compensation Table under Item 11 who were serving as Named Executive Officers as of March 27, 2024; and (4) all of our executive officers and directors as a group. Beneficial ownership is determined in accordance with the SEC rules. Shares of common stock subject to any warrants or options that are presently exercisable, or exercisable within 60 days of March 27, 2024 (which are indicated by footnote) are deemed outstanding for the purpose of computing the percentage ownership of the person holding the warrants or options, but are not treated as outstanding for the purpose of computing the percentage ownership of any other person. The percentage ownership reflected in the table is based on 495,092 shares of our common stock outstanding as of March 27, 2024. Except as otherwise indicated, the holders listed below have sole voting and investment power with respect to all shares of common stock shown, subject to applicable community property laws.

Item 13. CERTAIN RELATIONSHIPS, RELATED TRANSACTIONS AND DIRECTOR INDEPENDENCE

Director Independence

Although the Company is no longer listed on The Nasdaq Capital Market, our Board has determined that Dr. Simpson, Mr. Caldwell and Mr. Claiborne are “independent” under the current independence standards of both The Nasdaq Capital Market and the SEC, and have no material relationships with us (either directly or as a partner, shareholder or officer of any entity) that are inconsistent with a finding of their independence as members of our Board. Our Board has determined that Mr. Claiborne and Mr. Caldwell also are “independent” for purposes of service as the members of our Audit Committee. In making these determinations, our Board has broadly considered all relevant facts and circumstances, recognizing that material relationships can include commercial, banking, consulting, legal, accounting, and familial relationships, among others.

Transactions with Related Persons

As a result, the procedures followed by the Audit Committee to evaluate transactions with related persons require:
