ITEM 1. BUSINESS
Item 1. Business
We are a clinical stage pharmaceutical company leveraging our proprietary technology to develop novel therapies designed to cure cancers. Our goal is to extend the benefits of cancer treatments with surgery, radiation therapy, chemotherapy and immunotherapy. Radiation therapy (“RT”) is one of the most effective modalities for treating cancers. We are developing a pipeline of products designed to address the limitations of the current cancer therapies as well as to extend to the new applications of RT. We believe that our product candidates will enable us to deliver cancer treatments that are safer, more reliable and at a greater scale than that of the current standard of care.
The corporate structure is based on Shuttle Pharmaceuticals Holdings, Inc. (Nasdaq SHPH - a Delaware company) serving as a holding company with drug discovery and development performed in the Company’s wholly-owned subsidiary Shuttle Pharmaceuticals, Inc. (a Maryland Company) and diagnostics performed in the Company’s wholly-owned subsidiary Shuttle Diagnostics, Inc. (a Maryland Company). Our product candidates include Ropidoxuridine, a Phase II clinical-stage radiation sensitizer, a platform of HDAC inhibitors (SP-1-161, SP-2-225 and SP-1-303), and two preclinical, prostate cancer-oriented diagnostics assets - the PC-RAD Test, a blood test to predict clinical response to radiation therapy and the PSMA-B ligand for potential use as a theranostic agent.
In December 2023, we submitted an Investigational New Drug (“IND”) application with the U.S. Food and Drug Administration (“FDA”) to support the next phase of development of Ropidoxuridine. In January 2024, we received the ‘Safe to Proceed’ letter from the FDA for our IND application for the Phase II study of Ropidoxuridine (IPdR) as a radiation sensitizing agent during radiotherapy in patients with newly diagnosed IDH-wildtype glioblastoma with unmethylated MGMT promoter. Receipt of the letter allows us to commence the Phase II study of Ropidoxuridine (IPdR). We have applied for and received FDA approval of Orphan designation for Ropidoxuridine and RT for treating brain cancer (glioblastoma).
We believe our management team’s expertise in radiation therapy, combined modality cancer treatment and immuno-oncology will help drive the development and, if approved, the commercialization of these potentially curative therapies for patients with aggressive cancers.
Radiation Oncology has gone through transformative technological innovation over the last several years to better define tumors, allow improved shaping of radiation delivery and support dose escalation with shorter courses of treatment. Furthermore, achieving higher dose distributions within tumor volumes has reached a practical plateau, since cancers are frequently integrated with or surrounded by more sensitive normal tissues and further dose escalation increases risks of tissue necrosis. To increase cancer cures at maximally tolerated radiation doses, pharmacological and biological modifications of cells are needed to sensitize cancers, protect normal tissues, and stimulate the immune system to react against antigens produced by irradiated, damaged cancer cells. Drugs that show sensitizing properties, or the ability to make cancer cells more sensitive to radiation, offer a solution to this problem. Currently, such drugs are chemotherapy agents used off-label, and many have inherent toxicities since they were designed for direct cancer treatments and not for sensitization. However, the clinical value of using radiation sensitizing drugs in combination with RT has been accepted in a variety of cancer types, including gynecological, gastro-intestinal, pulmonary and other malignancies. Hence, there is a critical need for new drugs that preferentially sensitize cancer cells to radiation therapy and that stimulate the innate immune response against irradiated cancer cells. Furthermore, to advance precision medicine in radiation oncology, there is a need for imaging and molecular diagnostic tests for determining the extent of cancer spread in the body and for predicting clinical responses to therapy.
We are developing our products with the goal of addressing the unmet need in cancer treatment for a commercially marketable radiation response modifier solution that leads to greater sensitivity of cancer cells to ionizing radiation therapy. The goal of our products is to increase the therapeutic index for patients receiving radiation and to decrease radiation-related toxicities in patients with solid tumors. Our products operate across three areas related to the treatment of cancer with RT:
1. Sensitization of growing cancer cells, rendering them more susceptible to the effects of radiation therapy.
2. Activation of the DNA damage response pathway to kill cancer cells and protect adjacent normal cells.
3. Activation of the immune system to kill any remaining cells after RT.
Our platform technology allows for the creation of an inventory of products for radiation sensitizing, immune modulation, and protection of healthy tissue.
Operations to date have focused on continuing our research and development efforts to advance Ropidoxuridine clinical testing and improved drug formulation to advance HDAC6 inhibitor (SP-2-225) preclinical development and explore application of the PC-RAD Test, predictive biomarkers of radiation response. The clinical development of Ropidoxuridine has included completion of a Phase I clinical trial to establish drug bioavailability and a maximum tolerated dose for use in Phase II clinical trials. TCG GreenChem, Inc. (“TCG GreenChem”), with whom we have contracted for process research, development and Good Manufacturing Practices (“cGMP”) compliant manufacture of IPdR, has manufactured the active pharmaceutical ingredient (API) of Ropidoxuridine and the University of Iowa Pharmaceuticals has formulated the drug product for use in the Company’s upcoming Phase II clinical trial in brain cancer patients undergoing radiation therapy. The drug product (capsules) was shipped to contract research organization (CRO) Theradex Oncology and distributed to clinical trial sites that are fully approved to enroll patients in the trial. The Company received approval from the FDA to begin the clinical trial, after which time the FDA made recommendations to expand the clinical trial to include a randomized dose “optimization” step and we agreed with the recommendation. Meetings with engaged clinical sites to review the protocol documents have occurred and FDA required Institutional Review Board, or IRB approvals have been received. With FDA recommended changes incorporated into the revised protocol and the completion of site initiation visits, the Company has commenced its Phase II clinical study. The radiation biomarker project and the health disparities project have been completed and the Company is proceeding with plans for clinical validation and potential for commercialization of Ropidoxuridine as a radiation sensitizer.
We also worked with University of Iowa Pharmaceuticals to develop the formulation, produce the capsules, and which have been shipped to Contract Research Organization (CRO) Theradex Oncology for distribution to clinical trial sites. Both activities have now been completed. In addition, we received approval from the FDA to begin the clinical trial. The FDA made recommendations to expand the clinical trial and the Company agreed with the recommendation. With this change incorporated into the revised protocol, the Company commenced its Phase II clinical study with finalized agreements with all six of the planned site enrollment locations to administer the Phase II clinical trial of Ropidoxuridine and has enrolled the first three patients in October 2024.
Our Pipeline
We are currently developing a pipeline of small molecule radiation sensitizers and immune response regulating drugs. Our most advanced product candidate is Ropidoxuridine, an orally available halogenated pyrimidine with strong cancer radiation sensitizing properties in preclinical studies. In addition, we have a pipeline of complimentary product candidates that we are developing to address a host of solid tumor cancer indications. Our pipeline is represented in the diagram below:
Timeline for our clinical phase (Ropidoxuridine) and pre-clinical phase (HDAC inhibitors) pipeline.
Our lead product candidates include:
● Ropidoxuridine (IPdR) is our lead candidate radiation sensitizer for use in combination with RT to treat brain tumors (glioblastoma) and sarcomas. Phase I clinical trial results supported by an NIH contract to Shuttle Pharma and the NCI (CTEP) were reported in the medical journal, Clinical Cancer Research, in July 2019, by our SBIR subcontractor. Eighteen patients completed dose escalations to 1,800 mg/day for 30 days, establishing the maximum tolerated dose (MTD) of 1,200 mg/day in combination with RT. Four partial responses, nine stable disease and one progressive disease in target lesions were reported. Four patients did not have measurable disease and, as a result, were not evaluable. These Phase I trial results demonstrate oral bioavailability and an MTD of 1,200 mg per day for 28 days for use in combination with radiation for Phase II clinical trials that we proposed to perform in brain tumors and in sarcomas. The brain tumor, glioblastoma multiforme (GB) is eligible for orphan disease designations. Shuttle Pharma has advanced drug manufacture and formulation and prepared a clinical protocol of a “Phase 2 Single-Arm Study of IPdR as a Radiation Sensitizing Agent During Radiotherapy in Patients with Newly Diagnosed IDH-Wildtype MGMT Unmethylated Glioblastoma Multiforme.” In December 2023, we submitted an IND application with the FDA to support the next phase of development of Ropidoxuridine. In January 2024, we received the ‘Safe to Proceed’ letter from the FDA for our IND application for the Phase II study of Ropidoxuridine (IPdR) as a radiation sensitizing agent during radiotherapy in patients with newly diagnosed IDH-wildtype glioblastoma with unmethylated MGMT promoter. Receipt of the letter allows us to commence the Phase II study of Ropidoxuridine (IPdR). The clinical development of Ropidoxuridine has shown drug bioavailability and a maximum tolerated dose has been established for use in Phase II clinical trials. TCG GreenChem, Inc. (“TCG GreenChem”), with whom we have contracted for process research, development and cGMP compliant manufacture of IPdR, has successfully completed the manufacturing campaign for the active pharmaceutical ingredient (API) of Ropidoxuridine for use in the Company’s upcoming Phase II clinical trial in brain cancer patients undergoing radiation therapy. The Company also worked with University of Iowa Pharmaceuticals to develop the formulation and produce the capsules, which have been shipped to contract research organization (CRO) Theradex Oncology for distribution to clinical trial sites. Both activities have now been completed. In addition, Shuttle received approval from the FDA to begin the clinical trial. The FDA made recommendations that led to an expanded clinical trial to include randomized dose optimization and we agreed with the recommendation. We met with representatives from six candidate clinical sites to review the protocol documents and FDA required IRB approvals have been obtained. With FDA recommended changes incorporated into the revised protocol, the Company has now contractually engaged all six of the planned research centers which have begun performing clinical trials which have begun performing our Phase II clinical trial. Seventeen patients have enrolled in the study as of February 24, 2025 and half of those patients have already completed all seven courses of treatment with Ropidoxuridine.
● The Phase II clinical study is summarized below:
The above chart represents the schema for the Phase II clinical trial. The initial cohort of 40 patients will be randomized to one of two Ropidoxuridine doses. Twenty patients will receive the 1200 mg dose and 20 patients will receive the 960 mg dose. The optimum dose will be determined by comparing drug bioavailability and side-effects. The optimum dose will then continue to enroll 14 additional patients to provide the required 34 patients for statistical significance in comparison to historical controls.
● Ropidoxuridine and Tipiracil (IPdR/TPI) is a new combination formulation demonstrating extended bioavailability after oral administration in an animal model system. The IPdR/TPI formulation will undergo preclinical development for use as a radiation sensitizer and represents a “next generation” drug product for clinical evaluation.
● SP-2-225 is Shuttle Pharma’s pre-clinical class IIb selective HDAC inhibitor that selectively affects histone deacetylase HDAC6. SP-2-225 has effects on the regulation of the immune system. The interactions of RT with the immune response for cancer treatment are of great current interest, offering insight into potential mechanisms for primary site and metastatic cancer treatment. For this reason, Shuttle Pharma has selected SP-2-225 as the candidate lead HDAC inhibitor for preclinical development. We have contracted with investigators at Georgetown University to perform preclinical studies of immune activation after radiation therapy in an animal tumor model. With the introduction of check-point inhibitors, CAR-T therapies and personalized medicine in cancer, regulation of the immune response following RT is of significant clinical and commercial interest.
● SP-1-303 is Shuttle Pharma’s pre-clinical selective Class I HDAC inhibitor that preferentially affects histone deacetylases HDAC1 and HDAC3 members of the class I HDAC family of enzymes. SP-1-303 data show direct cellular toxicity in ER positive breast cancer cells. Furthermore, SP-1-303 increases PD-L1 expression. A manuscript reporting completed preclinical in vitro studies is in preparation. We plan to seek collaborations to complete SP-1-303 pre-clinical development in 2025.
Our Approach
We believe that we have established a leadership position in radiation sensitizer discovery and development. Over approximately seven years of research, we have identified two clinical phase product candidates and discovered new pre-clinical molecules using our proprietary platform technologies to increase the therapeutic index for patients receiving radiation for treatment of solid tumors. Our development strategy has four key pillars: (1) to improve the efficacy of RT by demonstrating improved disease-free survival rates in patients who undergo radiation therapy, (2) reduce the amount of radiation needed for a favorable tumor response, thereby limiting the potential for radiation related toxicities to healthy cells, (3) decrease the extent of surgery needed to remove cancers and improve quality of life, and (4) leverage our next generation technologies to create drugs that regulate the immune response assisting immune checkpoint and CAR-T therapies and other personalized medicines targeting cancers.
In addition to private and public investment into our candidate therapeutic technology, we have also competed for non-dilutive funding from the NIH to support our lead sensitizer and to explore development of complimentary diagnostic products. To date, we have completed three SBIR contracts awarded to Shuttle Pharma by the NIH to:
● Develop IPdR as a radiation sensitizer. This funding provided partial support for the Phase I clinical trial of Ropidoxuridine and RT.
● Develop prostate cancer cell cultures from African-American men, with donor matched normal prostate cells, establishing 50 pairs for accelerating research to reduce prostate cancer health disparities in African-American men. This project was funded under “Moonshot” designation. Shuttle Pharma is eligible to apply for additional SBIR (Phase IIb) funding to commercialize these cells for research purposes. Currently, cells from African-American patients are distributed, on request, to investigators who are conducting health disparities research. We plan to test new small molecules using these cellular reagents for health disparities screening.
● Develop a predictive biomarker for determining outcomes for prostate cancer patients following treatment with RT. This SBIR-funded project for blood test (PC-RAD Test) discovery and analytical validation were completed on March 15, 2022, and Shuttle Pharma intends to perform a clinical validation study. Shuttle Pharma has licensed the intellectual property for the prostate cancer predictive biomarker test from Georgetown University and will seek additional investment from the public market to advance clinical development through its Shuttle Diagnostics entity.
All three SBIR funded projects have been completed. The Company is eligible to apply for SBIR Phase IIb funding to advance the “Moonshot” health disparities or the predictive biomarker project. The NIH SBIR program is designed to encourage small businesses to engage in Federal Research/Research and Development (“R/R&D”) that has the potential for commercialization.
Shuttle Pharma’s scientists have also developed collaborations to invent intellectual properties for prostate cancer theranostics. From a clinical perspective, prostate-specific membrane antigen (PSMA) is a valuable target for diagnosis and therapy of prostate cancer. In a discovery project to develop a novel, boron-containing PSMA ligand to enhance proton radiation therapy of prostate cancer, we discovered PSMA-B, a molecule containing boron and demonstrating nanomolar binding activity to PSMA. Preclinical evaluations have been initiated to explore the PSMA-B ligand as a potential prostate cancer sensitizer in combination with proton therapy, as well as a PET diagnostic reagent and as a targeted prostate cancer therapeutic. By in-licensing our collaborator’s shares of the intellectual property, Shuttle Pharma has an exclusive license to the PSMA-B intellectual property and has filed a patent application. Theranostic molecules are suitable for diagnosis and therapy of cancers. The PSMA ligand is a molecule that binds to the PSMA, an enzyme that is highly expressed in prostate cancer cells. The PSMA ligand is currently used for imaging and therapy to detect and treat prostate cancer.
● Develop PSMA-B as a potential diagnostic and therapeutic molecule in pre-clinical models in collaboration with academic nuclear medicine programs. Shuttle Pharma has licensed the intellectual property for the prostate cancer predictive biomarker test from inventors and will seek additional investment from NIH by applying for grant applications and from the public market to advance clinical pre-development through its Shuttle Diagnostics entity.
Our Strategy
Our goal is to maintain and build upon our leadership position in radiation sensitization. We plan to develop Ropidoxuridine and the HDAC6 inhibitor (SP-2-225) and, if approved by the FDA, commercialize our product candidates for the treatment of cancers. While this process may require years to complete, we believe achieving this goal could result in new radiation sensitizer and immunotherapy products. Key elements of our strategy include:
● Capitalize on Ropidoxuridine as an orally available, small molecule radiation sensitizer. To date, there is one drug (Cetuximab, a monoclonal antibody) approved by the FDA specifically as a radiation sensitizer. If we are successful in developing Ropidoxuridine and obtaining FDA approval, a small molecule sensitizer would then be enabled for clinical applications for radiation sensitization indications.
● Expand our leadership position within radiation sensitizers. In addition to our traditional radiation sensitizers, we plan to advance our near-term pipeline to include radiation sensitizers for proton therapy. Proton Therapy is growing worldwide as a form of radiation therapy due to its unique beam shaping characteristics. As a result, this new technology offers a major opportunity for Shuttle Pharma to strive to develop an innovative and well-tolerated drug for proton therapy sensitization.
● Execute a disciplined business development strategy to strengthen our portfolio of product candidates. We have built our current product pipeline through in-house discovery, development, partnerships with leading academic institutions and through in-licensing. We will continue to evaluate new in-licensing opportunities and collaboration agreements with leading academic institutions and other biotechnology companies around programs that seek to address areas of high unmet need and for which we believe there is a high probability of clinical success, including programs beyond our target franchise areas and current technology footprint.
● Invest in our HDAC platform technology and maximize its utility across cancer therapies. We are initially applying the platform to develop drugs for cancer radiation sensitization, normal tissue radiation protection and post radiation immune stimulation. Based on the data we have obtained thus far, these drugs are immune regulatory. We intend to invest to develop other properties of our platform technology, as well.
● Enter into collaborations to realize the full potential of our platform. The breadth of our HDAC technology platform enables other therapeutic applications, including radiation sensitization and immune therapy. We intend to seek collaborations centered on our platform to maximize applications for cancer treatment.
● Establish Shuttle Diagnostics, Inc. as a subsidiary of SHPH to advance development of the predictive biomarker (PC-RAD Test) and the PSMA ligand (PSMA-B) to advance prostate cancer treatment.
Radiation Therapy
Radiation Oncologists use Radiation Therapy (RT) to treat cancers that cannot be completely removed by surgery but have not yet spread to distant sites within the body. RT has been a mainstay for the treatment of cancer malignancies for more than half a century. The combination treatment of radiation therapy and chemotherapy has involved the use of cytotoxic drugs, targeted biologic agents and targeted external beam radiation to increase the destruction of tumor cells and cure or delay cancer progression. The low number of drugs and biologic agents under investigation as radiation sensitizing agents highlights an unmet need for new approaches and agents that provide greater effectiveness, increased quality and better tolerability for patients.
Currently, “chemo-radiation” treatments are established in cancers of the head and neck, esophagus, lung, stomach, breast, brain, pancreas, rectum and uterine cervix. The ideal radiation sensitizer would reach the tumor in adequate concentrations and act selectively in the tumor, as compared to surrounding normal tissues. It would have predictable pharmacokinetics for timing with radiation therapy and could be administered with every radiation treatment approach. The ideal radiation sensitizer would have minimal toxicity or manageable enhancement of radiation toxicity.
The U.S. market for radiation sensitizing agents is experiencing dynamic growth through development of new radiation technology, the introduction of new agents, growth in the number of diagnosed patients in a variety of cancers and changes in treatment patterns. New agents have been introduced, including bevacizumab (Avastin®, Roche), panitumumab (Vectibix®, Amgen), temozolomide (Temodar®, Merck) and cetuximab (Erbitux®, Eli Lilly/Imclone), with potential as radiation sensitizing agents (though all but cetuximab are used off label); and all are recommended by the NCCN® (National Comprehensive Cancer Network) in clinical practice guidelines for use in combination with established therapies such as FOLFOX (leucovorin, 5-FU, oxaliplatin), CapeOX (capecitabine, oxaliplatin) and FOLFIRI (leucovorin, 5-FU, irinotecan).
The growth in the number of patients with cancers is being driven by an aging population and improved diagnostic tools. According to the National Cancer Institute (NCI), more than half (~50 - 60%) of all cancer patients undergo some type of radiotherapy during the course of their treatment. Confirming the patient estimate from the NCI, the American Society for Therapeutic Radiology and Oncology (ASTRO) factsheet states approximately 67% of approximately 1.25 million cancer patients are treated with radiation therapy annually, either one or more times. In addition, in a study published by the Journal of Clinical Oncology in 2016, it is estimated that the number of cancer patients needing radiation therapy will increase by 22% in the next 10 years. (See “The Future of Radiation Oncology in the United States From 2010 to 2020: Will Supply Keep Pace With Demand?” Benjamin D. Smith, Bruce G. Haffty, Lynn D. Wilson, Grace L. Smith, Akshar N. Patel, and Thomas A. Buchholz Journal of Clinical Oncology 2010 28:35, 5160-5165).
The American Society of Clinical Oncology (ASCO) estimates more than 80% of cancers in the U.S. occur in people in the age group of 50 and above with over 60% of cancers occurring in those 65 and over. (See, 2018 Clinical Cancer Advances Report, American College of Clinical Oncology, 2018). For example, according to the American Cancer Society (ACS), more than 90% of colorectal cancer patients are individuals aged 50 years and older, with approximately 40% of all cases occurring in patients aged 75 years and over. The Colon Cancer Alliance estimates that 90% of new cases and 95% of deaths from colorectal cancers occur in people aged 50 or older. Also, the U.S. Census estimates that the age group of 65-84 will grow by 23% within the next five years, indicating a likely increase in the overall number of cancer patients in the U.S.
ROPIDOXURIDINE
The halogenated thymidine (TdR) analogs, bromodeoxyuridine (BUdR) and iododeoxyuridine (IUdR), are a class of pyrimidine analogs that have been recognized as potent radiosensitizing agents since the early 1960s. (See Kinsella TJ. An Approach to the Radiosensitization of Human Tumors. Cancer J Sci Am. Jul-Aug 1996:2(4); 184-193). Their cellular uptake and metabolism are dependent on the TdR salvage pathway where they are initially phosphorylated to the monophosphate derivative by the rate-limiting enzyme, thymidine kinase (TK). (See Shewach DS, Lawrence TS. Antimetabolite radiosensitizers. J Clin Oncol, Sep 10 2007; 25(26):4043-4050). After sequential phosphorylation to triphosphates, they are then used in DNA replication, in competition with deoxythymidine triphosphate (dTTP), by DNA polymerase. DNA incorporation is a prerequisite for radiosensitization of human tumors by the halogenated TdR analogs, and the extent of radiosensitization correlates directly with the percentage TdR replacement in DNA. (See Lawrence TS, Davis MA, Maybaum J, Stetson PL, Ensminger WD. The Dependence of Halogenated Pyrimidine Incorporation and Radiosensitization on the Duration of Drug Exposure. International Journal of radiation oncology, biology, physics. Jun 1990; 18(6);1393-1398). The molecular mechanisms of radiosensitization are most likely the result of increased susceptibility of TdR analog-substituted DNA to the generation of highly reactive uracil free radicals by ionizing radiation (IR), which may also damage unsubstituted complementary-strand DNA. Repair of IR damage may also be reduced by pre-IR exposure to these analogs.
The rationale for using Ropidoxuridine as a radiation sensitizer is based on prior clinical studies with the active metabolite IUdR; identified in NIH laboratories as a potent radiation sensitizer. Ropidoxuridine is an orally available prodrug of IUdR. In the body, Ropidoxuridine is metabolized in the liver into IUdR. IUdR is incorporated into the DNA of actively growing cells and when cells are exposed to ionizing radiation, DNA strand breaks are generated, resulting in more cell death and radiation sensitization. (See Gurkan E, Schupp JE, Aziz MA, Kinsella TJ, Loparo KA. Probabilistic modeling of DNA mismatch repair effects on cell cycle dynamics and iododeoxyuridine-DNA incorporation. Cancer Res. Nov 15 2007; 67(22):10993-11000).
Most of the clinical efficacy data were obtained from NIH supported studies performed with IUdR, the active metabolite of Ropidoxuridine. However, IUdR requires constant infusion over six weeks of therapy which creates a significant compliance issue for patients. Ropidoxuridine can be given as a capsule for oral administration, resulting in greater ease of medication delivery and potentially improved compliance and fewer complications.
Over the last 20 years, there has been renewed interest in these halogenated TdR analogs as experimental radiation sensitizers in selected cancer patient groups. These analogs are rapidly metabolized in both rodents and humans, principally with cleavage of deoxyribose and subsequent dehalogenation by hepatic and extrahepatic metabolism, when given as a bolus infusion with a plasma half-life of <5 min. Consequently, prolonged continuous or repeated intermittent drug infusions over several weeks before and during irradiation are necessary, based on in vivo human tumor kinetics, to maximize the proportion of tumor cells that incorporate these analogs into DNA during the S phase of the cell cycle. (See Fowler JF, Kinsella TJ. The Limiting Radiosensitization of Tumors by S-phase Sensitizers. Br J Cancer. 1996;74 (Suppl)(27):294-296). Phase I and Phase II trials using prolonged continuous or repeated intermittent intravenous infusions of BUdR or IUdR before and during radiation therapy (RT) have focused principally on patients with high-grade brain tumors. These clinically radiation resistant tumors can have a rapid proliferation rate (potential tumor doubling times of 5-15 days) and are surrounded by non-proliferating normal brain tissues that show little to no DNA incorporation of the TdR analogs. As such, high-grade brain tumors are ideal targets for this approach to radiation sensitization. In Phase I/Phase II clinical trials, prolonged survival outcomes were observed compared to RT alone in patients with anaplastic astrocytomas and in patients with glioblastoma multiforme IUdR continuous IV infusion (1000 mg/m2/ day/ 14 days), Total 39 patients (F. Sullivan, et al. Int J Radiat Oncol Biol Phys. 1994; 30(3):583-90.) A therapeutic gain in clinical radiation sensitization using these halogenated TdR analogs was proposed for other types of poorly responsive (radiation resistant) cancers, including locally advanced cervical cancer, head and neck cancers, unresectable hepatic metastases from colorectal cancers, and locally advanced sarcomas, based on the results of other Phase I/Phase II clinical trials.
Target Indication: Glioblastoma, Sarcomas and Rectal Cancers
After completion of the Phase I clinical trial of Ropidoxuridine and RT in advanced GI cancers, we proposed to perform Phase II efficacy clinical trials in brain tumors (glioblastoma), soft tissue sarcomas, and rectal cancers. Glioblastoma multiforme is a deadly malignancy of the brain with no known cure. Radiation therapy provides delay of disease progression and is standard of care following surgical resection or biopsy. Radiation therapy is combined with Temodar, a drug that has shown activity (~ four months survival benefit) in treating brain tumors. Preliminary data using radiation therapy in combination with IUdR resulted in a delay of disease progression of up to six months. We propose to test IPdR in combination with radiation therapy in the Phase II clinical trial. Similarly, delay in disease progression has been observed following treatment of sarcomas by the combination of IUdR and RT. Based on the Phase I data of our clinical trial we know that therapeutic levels of IUdR are reached by administering the orally available prodrug, IPdR.
Clinical Data
The Phase I results of the clinical trial supported by an SBIR contract to Shuttle Pharma and a sub-contract to the Brown University Oncology Group (BrUOG) at the LifeSpan/Rhode Island Hospital were reported by the subcontractor at the 30th EORTC-NCI-AACR Symposium in November 2018 and in the medical journal, Clinical Cancer Research, in 2019. Eighteen patients completed dose escalation to 1800 mg/day for 30 days, establishing the maximum tolerated dose (MTD) of 1,200 mg/day in combination with RT. Therapeutic blood levels of IUdR were achieved. Four patients were scored as partial responses, nine patients had stable disease and one patient progressed in the target lesions. These data support advancing IPdR and RT to clinical trials for the FDA to determine efficacy.
Development Plan
A key to driving the Ropidoxuridine product forward is the development of a clinical plan with aggressive timelines and support within the radiation oncology community to participate in clinical trials with the appropriate patients to ensure a comprehensive NDA dossier for each product. Initially, the plan is focused on the Phase I and Phase II clinical trials. Upon completion of Phase II studies, we will determine whether to extend the Phase II study to a randomized Phase II, or to perform a randomized Phase III clinical trial. Such determination will be based on results of the initial clinical trials and the end of a Phase II meeting with the FDA. Shuttle Pharmaceuticals requested and received FDA orphan drug status for Ropidoxuridine as a clinical radiation sensitizer for treatment of glioblastoma and pre-operative treatment of soft tissue sarcomas. As a result, the application for “orphan” designation for Ropidoxuridine with RT for glioblastoma has been approved. The application for sarcomas, however, was not approved and will require addressing certain FDA comments and resubmission. The IPdR/TPI formulation clinical plan will focus on resectable stage II and III rectal cancer patients.
Our clinical plan for Ropidoxuridine development as implemented to date, includes:
● GMP manufacture and formulation of 24 kg of Ropidoxuridine for use in clinical trials has been completed.
● The IND for a Phase II clinical trial of Ropidoxuridine and RT in glioblastoma has been approved for the study to proceed.
● The contract research organizations (CRO), Theradex Oncology has been engaged to assist in the performance the Phase II clinical trial.
● Completion of the Phase II clinical trial in glioblastomas to determine appropriate dosing, effectiveness and tolerability of the treatment.
The data obtained from the NIH/NCI SBIR funded Phase I clinical trial supported efforts to raise capital to enable performing the Phase II clinical trials of Ropidoxuridine. We aim to conduct and complete the Phase II clinical trial so that we may present data to the FDA for its determination of efficacy. We believe this will support our efforts to raise the additional required capital to complete Phase II and to fund the Phase III clinical trials and seek FDA approval of an NDA with “orphan” designation.
The clinical plan for the IPdR/TPI formulation will focus on resectable Stage II and Stage III rectal cancer patients and on recurrent glioblastoma treated with proton therapy. Nonetheless, we cannot guarantee the successful completion of any of these trials. Our inability to meet any of the aforementioned milestones in the Phase II or Phase III clinical trials will cause us to be unable to proceed with our present efforts and will likely cause us to be unable to raise additional funds.
Our HDAC Small Molecule Delivery Platform
General
Since the founding of Shuttle Pharma, our discovery research and development efforts have been focused on our small molecule technology delivery platform which uses HDAC inhibitors, designed to target cancer cells, while protecting healthy tissue.
HDACs are a class of enzymes that regulate gene expression through chemical modification of histones and non-histone proteins. Increased HDAC activity leads to a more condensed chromatin (which is a protein complex consisting of DNA and other proteins), decreased gene expression and loss of key gene products, including tumor suppressor gene function. Inhibition of HDAC activity leads to a more open chromatin and increased expression of the key gene products. This chromatin modification underlies the epigenetic cellular regulatory system and is an area of intense investigation.
Our research and development efforts to date have focused on the discovery of novel, dual functional molecules for potential use in cancer treatment as radiation sensitizers of cancers, protectors of normal tissues, and activators of the immune responses to antigens expressed by irradiated cancer cells. To date, we have produced three candidate molecules:
● SP-1-161, a candidate lead of compounds demonstrating activation of the “ATM” gene product (mutated in Ataxia-Telangiectasia). Ataxia-Telangiectasia is a human genetic disease characterized by neurological, immunological and radiobiological clinical features.
● SP-2-225, a candidate lead of compounds demonstrating Class II (HDAC6) selective inhibition. HDAC6 is a molecule integral to the presentation of antigens by macrophages to T-lymphocytes.
● SP-1-303 is a candidate Class I HDAC inhibitor with preferential efficacy against ER positive cancers.
SP-1-161 - A Dual Functional Agent
SP-1-161 is an HDAC inhibitor of the hydroxamate chemical class of compounds and an ATM activator of the indole chemical class. HDACs modify histones and non-histone proteins, which are key components of the chromatin structure, gene expression regulation, and cell growth. HDAC inhibitors inhibit cell proliferation, angiogenesis and immunity. Eighteen human HDACs have been identified, subdivided into four classes based on sequence and functional homology. In cancer cells, HDAC activity silences tumor suppressor genes important for cell growth regulation and to chromosomal instability. Abnormal HDAC activity is also associated with tumor cell growth, invasion, metastasis and resistance to therapy. Therefore, inhibitors of HDACs have emerged as anti-cancer agents for cancer therapy. Vorinostat and romidepsin have been approved by the FDA for treatment of patients with relapsed or refractory T-cell lymphomas. In addition, panobinostat received FDA approval for treatment of recurrent multiple myeloma in combination with bortezomib and dexamethasone.
In preclinical studies, SP-1-161 inhibited the activity of pan-HDACs and activated the ATM gene product. ATM is a critical protein for the activation of the cell stress response for cellular recovery from radiation exposure in normal cells, but not in cancer cells. ATM activates the P53 protein, referred to as the “guardian of the genome,” and serves as a tumor suppressor critical for normal cell function and activation of programmed cell death in cancer cells.
In preclinical studies, SP-1-161 protected normal breast epithelial cells (184A1) following exposure to ionizing radiation while increasing sensitivity of breast cancer cells (MCF7). SP-1-161 provides this dual function in a single molecule and this molecule is differentiated from other HDAC inhibitors by treatment of cancers while protecting normal cells. (See Grindrod S, Brown M, Jung M. “Development of dual Function Small Molecules as Therapeutic Agents for Cancer Research,” Poster presentation #A178, American Association of Cancer Research Oct 2017).
SP-2-225
SP-2-225 is a selective HDAC inhibitor that affects histone deacetylase (HDAC6) and is a member of the class IIb HDAC family. Class II HDACs play important roles in cancer motility, invasion, neurological diseases, and immune checkpoint. HDAC6 inhibition has been most extensively studied for its role in the treatment of hematological cancers. HDAC6 is unique among HDAC enzymes in having two active catalytic domains and a unique physiological function. In addition to the modification of histones, HDAC6 targets specific substrates including α-tubulin and HSP90, and are involved in protein trafficking and degradation, cell shape and migration. Selective HDAC6 inhibitors are an emerging class of pharmaceuticals due to the involvement of HDAC6 in pathways related to neurodegenerative diseases, cancer and immunology. Specifically, its potential to affect regulation of the immune system and enhance the immune response in cancer is of great interest. With the introduction of check-point inhibitors, CAR-T therapies and personalized medicine in cancer, regulation of the immune response to this therapy is of significant clinical and commercial interest. (See Noonepalle SKR, Grindrod S, Aghdam N, Li X, Gracia-Hernandez M, Zevallos-Delgado C, Jung M, Villagra A, Dritschilo A. Radiotherapy-induced Immune Response Enhanced by Selective HDAC6 Inhibition. Mol Cancer Ther. 2023 Dec 1;22(12):1376-1389. doi: 10.1158/1535-7163.)
Selective inhibition of HCAC6 reduces dose limiting side effects associated with non-selective HDAC inhibitors. Selective HDAC6 inhibitors may be combined with other cytotoxic agents. Shuttle’s discovery of selective HDAC inhibitors has yielded several HDAC6 selective candidate molecules including SP-2-225. HDAC6 inhibitors are under investigation for roles in the treatment of diseases such as multiple myeloma.
SP-1-303 - Target Indication: Breast Cancer
Histone deacetylase inhibitors sensitize cancers to the effects of radiation, protect normal tissues from radiation injury and activate the immune system. SP-1-303 is a selective Class I HDAC inhibitor that inhibits HDAC1, 3 and 6 and has direct cellular toxicity in ER positive breast cancer cells. Furthermore, SP-1-303 increases the PD-L1 expression level in a time-dependent manner, support combination of SP-1-303 with an immune checkpoint blocker to enhance the therapeutic benefits. We are currently conducting preclinical efficacy studies of these molecules.
Development Plan
The HDAC inhibitor platform of candidate molecules will require pre-clinical evaluation, completion of IND-enabling studies and the lead drug candidates will be tested in Phase I clinical trials for pharmacokinetics and MTD determination. We have three lead candidates for potential development for the treatment of solid tumors, including breast cancer, lung cancer and multiple myeloma.
The results of Phase I and Phase II clinical trials will determine further drug development and Shuttle will seek to establish collaborative partnerships with other pharmaceutical companies to complete pre-clinical and clinical development, drug manufacturing and marketing of our product candidates. In the event we are unsuccessful in completing our clinical trials at any stage, or in the event we obtain negative results, we will likely be unable to raise additional funding related to our HDAC studies or will have to change direction of our research efforts regarding the HDAC inhibitor platform of candidate molecules.
Our Manufacturing Strategy
We have no manufacturing facilities that are owned or operated by us. We have performed laboratory scale synthesis and testing in our research laboratories in Gaithersburg, Maryland. GMP synthesis of API, drug formulation and human dosage preparation will be performed under contracts with third-party manufacturers.

Competition “Off-Label” Use
Drugs with radiation sensitizing properties.
Our Product Candidates
We are advancing a clinical stage product candidate, Ropidoxuridine, that we believe will target cancer cells while protecting healthy tissue when used in conjunction with RT.
Ropidoxuridine
Ropidoxuridine, an orally available halogenated pyrimidine with strong cancer radiation sensitizing properties, is our lead “clinical phase” product candidate. Halogenated pyrimidines are incorporated into DNA by rapidly growing cancer cells and become more sensitive to the effects of RT. We have received an SBIR contract from the NIH to fund a Phase I clinical trial in collaboration with Brown University at the Lifespan/Rhode Island Hospital to determine the maximum tolerated dose in patients with advanced gastrointestinal cancers. In connection with the trial, NCI approved the Phase I clinical protocol and provided drug and clinical data management support to Rhode Island Hospital. The Phase I clinical trial has been completed and the results support advancing Ropidoxuridine to Phase II clinical trials of brain tumors, sarcomas and other tumors.
The following tables provide data from reported clinical trials of Iododeoxyuridine and RT therapy in brain cancers (glioblastoma multiforme) and high-grade sarcomas. Our primary strategy for Ropidoxuridine and RT therapy is to provide oral drug delivery to effect radiation sensitization of cancers and validate effectiveness in glioblastoma and sarcoma, potential “Orphan” indications.
Brain Cancer Treatment

In addition to our primary product candidate, we are developing and planning to develop other cancer radiation sensitizers and radiation protectors, which target protecting normal tissue during the administration of RT, and other products utilizing our HDAC small molecule technology platform.
SBIR Contracts
The SBIR Program
The Small Business Innovation Research or SBIR, program, as developed by Congress under the Small Business Innovation Development Act of 1982, is designed to encourage domestic small businesses to engage in Federal Research/Research and Development (“R/R&D”) that has the potential for commercialization. Through a competitive awards-based program, SBIR enables small businesses to explore their technological potential and provides the incentive to profit from its commercialization. Some of the SBIR’s program goals include stimulating technological innovation, meeting Federal research and development needs and encouraging participation in innovation and entrepreneurship.
The SBIR program is a three-phase program. Phase 1 is to establish the technical merit and commercial potential of the proposed R/R&D efforts. Phase 2 is to continue the R/R&D efforts initiated in Phase 1 and funding is based on the results achieved in Phase 1. Phase 3 allows for the small business to pursue commercialization objectives resulting from the Phase 1 and 2 R/R&D activities. In addition, companies that have successfully completed Phases I and II are also eligible to apply for Phase IIb funding.
In addition to the SBIR contract to fund our Phase I clinical study on Ropidoxuridine in combination with RT for treatment of advanced gastrointestinal cancers, we have also received awards of SBIR contracts from the NIH to address prostate cancer health disparities and prostate cancer radiation biomarker development.
As of the date of this Annual Report, all SBIR contracts received by the Company have been completed. The Company submitted a final report for SBIR contract #75N81018C00031 on March 28, 2022. The following summary of terms for the three Phase II SBIR contracts is provided below.
Summary of SBIR Contracts
● SBIR contract #261201400013C: Phase I ($191,971) and Phase II ($1,428,117) for Clinical Development of IPdR for Radiosensitization, dates September 19, 2014 through August 3, 2017. Subcontract to Brown University/LifeSpan Rhode Island Hospital. No related intellectual property.
● SBIR contracts # HHSN261201600038C; Phase I ($224,687) and #261201800016C: Cell-Based Models for Prostate Cancer Health Disparity Research - Moonshot Project (Phase II), award amount $1,484,350, dates September 19, 2016 through September 16, 2021. Subcontract to Georgetown University. Intellectual property consists of cell cultures and is property of Shuttle Pharmaceuticals, Inc. via licensing agreement.
● SBIR contracts #HHSN261201600027C ($299,502) and #75N81018C00031: Predictive Biomarkers of Prostate Cancer Patient Sensitivity for Radiation Late Effects, award amount $1,903,015, dates September 16, 2019 through March 15, 2022. Subcontract to Georgetown University. Intellectual property is owned by subcontractor Georgetown University with option to license to Shuttle Pharmaceuticals, Inc.
Prostate Cancer Studies to Address Health Disparities
Prostate cancer health disparities studies have shown that African American men are at higher risk for developing prostate cancer, as well as at higher risk of cancer specific death rates as compared to Caucasian American men. The causes of disparities have been attributed to socioeconomic differences, environmental exposures and biological factors. Most disparities studies have been population based, in part, due to the lack of relevant in vitro and in vivo models to support biological studies.
Shuttle Pharma has been awarded Phase I and II SBIR contracts entitled “Cell-based models for prostate cancer health disparity research” to develop African American prostate cancer cell lines with donor matched normal prostate epithelial cell lines from African American men.
The commercialization of the prostate cells will require additional support through the SBIR funding mechanism. Companies that have completed Phase I and II SBIR awards are eligible to apply for Phase IIb SBIR funding. These awards were historically intended to de-risk a project by providing matching funding for product development to commercialization. We intend to apply for such government funding to advance laboratory facilities and to expand the availability of the cell cultures. We did not raise capital through our IPO for the health disparities project. Should we not be successful with SBIR IIb funding, we will pause and may have to terminate this project.
Prostate Cancer Biomarker Development
Patients treated for prostate cancer may experience treatment related late effects that adversely affect quality of life and may prove life-threatening. Shuttle Pharma has been awarded a Phase I SBIR contract entitled “Predictive biomarkers for prostate cancer patient sensitivity for radiation late effects” to determine the technical and commercial feasibility of a biomarker panel predictive of radiation mediated late effects in patients treated for prostate cancer.
Through collaboration with Georgetown University, patients treated with SBRT for prostate cancers were analyzed for urinary and rectal symptoms and their blood was analyzed by mass spectroscopy for predictive biomarkers. The discovery and validation of metabolite panels to serve as a predictive biomarker of patient outcomes following radiation therapy and supports future development and commercialization of a diagnostic product through a Phase 2 SBIR effort.
The development to commercialization of the metabolite predictive biomarker panel requires additional support through the SBIR funding mechanism. We will be eligible to apply for Phase IIb SBIR funding for the next round of solicitation. A Phase IIb funding may help de-risk the project by providing matching funds for performing the clinical validation trial for product development to commercialization. We intend to apply for such government funding to advance this project. We also intend to raise capital through the public market for predictive biomarker development through the Shuttle Diagnostics entity. Should we not be successful in obtaining SBIR IIb funding, we will terminate this project.
Collaborative Arrangements
While we intend to enter into selective collaborative arrangements to further develop our drug candidates in the future, at present we have not entered into any collaborative arrangements with third parties to develop our drug candidates as we are still completing clinical trials and, as a result, there can be no assurance that we will be able to do so on commercially reasonable terms or otherwise.
Intellectual Property
We invest significant amounts of funds in research and development. Our research and development expenses before contract reimbursements were $3,618,796 and $3,517,093 for the fiscal years ended December 31, 2024 and 2023 respectively, without receiving any reimbursements.
We are seeking multifaceted protection for our intellectual property that includes licenses, confidentiality and non-disclosure agreements, copyrights, patents, trademarks and common law rights, such as trade secrets. We enter into confidentiality and proprietary rights agreements with our employees, consultants, collaborators, subcontractors and other third parties and generally control access to our documentation and proprietary information.
As of the date of this Annual Report, we have 20 granted patents overall, of which we have five core patents granted by the USPTO with respect to various aspects of our HDAC small molecule delivery platform and one for Ropidoxuridine, our lead product candidate. The following table sets forth Shuttle Pharma’s key patents to date:
Summary of Shuttle Pharma’s Key Intellectual Property Portfolio
Morgan, Lewis & Bockius LLP prepared patent applications related to Ropidoxuridine (IPdR) and HDAC inhibitors, and, in the fourth quarter of 2018, found no freedom to operate (FTO) issue for Ropidoxuridine used as radiosensitizer and used with tipiracil, and HDAC inhibitors SP-1-161 and SP-2-225.
Our strategy around protection of our proprietary technology, including any innovations and improvements, is to obtain worldwide patent coverage with a focus on jurisdictions that represent significant global pharmaceutical markets. Generally, patents have a term of twenty years from the earliest priority date, assuming that all maintenance fees are paid, no portion of the patent has been terminally disclaimed and the patent has not been invalidated. In certain jurisdictions, and in certain circumstances, patent terms can be extended or shortened. We are obtaining worldwide patent protection for at least novel molecules, composition of matter, pharmaceutical formulations, methods of use, including treatment of disease, methods of manufacture and other novel uses for the inventive molecules originating from our research and development efforts. We continuously assess whether it is strategically more favorable to maintain confidentiality for the “know-how” regarding a novel invention rather than pursue patent protection. For each patent application that is filed we strategically tailor our claims in accordance with the existing patent landscape around a particular technology.
There can be no assurance that an issued patent will remain valid and enforceable in a court of law through the entire patent term. Should the validity of a patent be challenged, the legal process associated with defending the patent can be costly and time consuming. Issued patents can be subject to oppositions, interferences and other third-party challenges that can result in the revocation of the patent limit patent claims such that patent coverage lacks sufficient breadth to protect subject matter that is commercially relevant. Competitors may be able to circumvent our patents. Development and commercialization of pharmaceutical products can be subject to substantial delays and it is possible that at the time of commercialization any patent covering the product has expired or will be in force for only a short period of time following commercialization. We cannot predict with any certainty if any third-party U.S. or foreign patent rights or other proprietary rights will be deemed infringed by the use of our technology. Nor can we predict with certainty which, if any, of these rights will or may be asserted against us by third parties. Should we need to defend ourselves and our partners against any such claims, substantial costs may be incurred. Furthermore, parties making such claims may be able to obtain injunctive or other equitable relief, which could effectively block our ability to develop or commercialize some or all of our products in the U.S. and abroad and could result in the award of substantial damages. In the event of a claim of infringement, we or our partners may be required to obtain one or more licenses from a third party. There can be no assurance that we can obtain a license on a reasonable basis should we deem it necessary to obtain rights to an alternative technology that meets our needs. The failure to obtain a license may have a material adverse effect on our business, results of operations and financial condition.
We also rely on trade secret protection for our confidential and proprietary information. No assurance can be given that we can meaningfully protect our trade secrets on a continuing basis. Others may independently develop substantially equivalent confidential and proprietary information or otherwise gain access to our trade secrets.
It is our policy to require our employees and consultants, outside scientific collaborators, sponsored researchers and other advisors who receive confidential information from us to execute confidentiality agreements upon the commencement of employment or consulting relationships. These agreements provide that all confidential information developed or made known to these individuals during the course of the individual’s relationship with the company is to be kept confidential and is not to be disclosed to third parties except in specific circumstances. The agreements provide that all inventions conceived by an employee will be the property of our company. There can be no assurance, however, that these agreements will provide meaningful protection or adequate remedies for our trade secrets in the event of unauthorized use or disclosure of such information.
Our success will depend in part on our ability to obtain and maintain patent protection, preserve trade secrets, prevent third parties from infringing upon our proprietary rights and operate without infringing upon the proprietary rights of others, both in the U.S. and other territories worldwide.
Manufacturing and Supply
We do not currently own or operate manufacturing facilities for the production of preclinical, clinical or commercial quantities of any of our product candidates. We currently use a number of our suppliers for the raw materials and formulation to meet the preclinical and any clinical requirements of our product candidates. We do not have a long-term agreement with any of these parties and we believe alternative sources of supply exist.
We intend to enter into collaborations for the manufacture of our product candidates, with our collaborators assuming responsibility for such manufacturing. Manufacturing is subject to extensive regulations that impose various procedural and documentation requirements, which govern record keeping, manufacturing processes and controls, personnel, quality control and quality assurance, among others. Any collaborator or third-party contract manufacturer we use would need to be compliant with cGMP. cGMP is a regulatory standard for the production of pharmaceuticals that will be used in humans.
Sales and Marketing
Our current focus is on the development of our existing portfolio, the completion of clinical trials and, if and where appropriate, the registration of our product candidates. We currently do not have marketing, sales and distribution capabilities. If we receive marketing and commercialization approval for any of our product candidates, we intend to market the product either directly or through collaborations, strategic alliances and distribution agreements with third parties. The ultimate implementation of our strategy for realizing the financial value of our product candidates is dependent on the results of clinical trials for our product candidates, the availability of funds and the ability to negotiate acceptable commercial terms with third parties.
Employees
As of the date of this Annual Report, we have nine full-time employees, including our six executive officers and three employees engaged in research and development. We consider our relationship with our employees to be good.
Nasdaq Deficiency and 2024 Reverse Stock Split
Our common stock currently is listed for quotation on the Nasdaq Capital Market (the “Nasdaq”). We are required to meet Nasdaq listing rules in order to maintain such listing, including a requirement that the Company maintain stockholders’ equity of at least $2.5 million. On September 10, 2024, we received a letter from the Nasdaq Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that it is no longer in compliance with the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires listed companies to maintain stockholders’ equity of at least $2.5 million. Our plan to regain compliance has been accepted by Nasdaq and now we have an extra 180-days, or until March 10, 2025, to regain compliance. However, there can be no assurance that the Company will be able to regain compliance and maintain our listing on the Nasdaq Capital Market. If the Company fails to regain compliance during the extended compliance period, or if the Company fails to satisfy another Nasdaq requirement for continued listing, Nasdaq could provide the Company with notice that the our securities will become subject to delisting. In that event, we will have an opportunity to appeal Nasdaq’s decision to a hearings panel.
On December 31, 2024, the Company received a letter from Nasdaq’s Staff stating that for the 30 consecutive business day period between November 15, 2024 to December 30, 2024 the Company’s common stock had failed to maintain a minimum closing bid price of $1.00 per share, as required for continued listing on The Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”). Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company has a period of 180 calendar days, or until June 30, 2025 (the “Compliance Period”), to regain compliance with the Minimum Bid Price Requirement. To regain compliance, the closing bid price of the Company’s common stock must meet or exceed $1.00 per share for a minimum of 10 consecutive trading days.
On August 31, 2023 we received a letter from Nasdaq stating that for the 30 consecutive business days the company had failed to meet the Minimum Bid Price Requirement. In accordance with Nasdaq rules, the Company was provided with an initial period of 180 calendar days, or until February 27, 2024, to regain compliance with the Minimum Bid Price Requirement and a second Grace Period on February 19, 2024 through August 26, 2024. As we had still not regained compliance by August 2024, in order to regain compliance with the Minimum Bid Price Requirement, on August 6, 2024, we filed an amendment to our certificate or incorporation to effect a 1-for-8 reverse stock split of our outstanding common stock (the “2024 Reverse Stock Split”). The 2024 Reverse Stock Split became effective on August 13, 2024, when the Company’s common stock opened for trading on Nasdaq on a post-split basis under the Company’s existing trading symbol, “SHPH.” Subsequently, on August 27, 2024, we received notice from Nasdaq that we had regained compliance with the Minimum Bid Price Requirement.

ITEM 1A. RISK FACTORS
Item 1A. Risk Factors
An investment in our securities involves a high degree of risk. You should carefully consider all of the risks described below, together with the other information contained in this Annual Report on Form 10-K, including our financial statements and related notes elsewhere, before making a decision to invest in our securities. If any of the following events occur, our business, financial condition and operating results may be materially adversely affected. In that event, the trading price of our securities could decline, and you could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business. Certain statements below are forward-looking statements.
Summary Risk Factors
The risks described under the heading “Risk Factors” beginning on page 25 of this Annual Report on Form 10-K may cause us not to realize the full benefits of our strengths and/or may cause us to be unable to successfully execute all or part of our strategy. Some of the more significant challenges we face include:
● Our ability to continue as a going concern in the near term is dependent upon us successfully raising additional equity or debt financing to fund our operations.
● Presently, there is substantial regulatory uncertainty surrounding future access to government funding of research activities, including access to grants awarded by the NIH which have traditionally provided support for certain of Shuttle Pharma’s research activities.
● Our success is primarily dependent on the successful development, regulatory approval and commercialization of our product candidates, all of which are in the early stages of development.
● We currently have no source of product sales revenue.
● We face competition from entities that have developed or may develop product candidates for our target disease indications, including companies developing novel treatments and technology platforms based on modalities and technology similar to ours. If these companies develop technologies or product candidates more rapidly than we do or their technologies, including delivery technologies, are more effective, our ability to develop and commercialize product candidates may be adversely affected.
● If we fail to comply with U.S. and foreign regulatory requirements, regulatory authorities could limit or withdraw any marketing or commercialization approvals we may receive and subject us to other penalties that could materially harm our business.
● If we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected.
● If we are not able to obtain and enforce patent protection for our technologies or product candidates, development and commercialization of our product candidates may be adversely affected.
● We or our licensors, or any future collaborators or a strategic partners may become subject to third party claims or litigation alleging infringement of patents or other proprietary rights or seeking to invalidate patents or other proprietary rights, and we may need to resort to litigation to protect or enforce our patents or other proprietary rights, all of which could be costly, time consuming, delay or prevent the development and commercialization of our product candidates, or put our patents and other proprietary rights at risk.
● If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.
● We may be unable to obtain U.S. and/or foreign regulatory approval and, as a result, unable to commercialize our product candidates.
● Any drugs we develop may become subject to unfavorable pricing regulations, third-party reimbursement practices or healthcare reform initiatives, thereby harming our business.
● Our ability to obtain services, reimbursement or funding from the federal government may be impacted by possible reductions in federal spending.
● If any of our product candidates receives marketing approval and we or others later identify undesirable side effects caused by the product candidate, our ability to market and derive revenue from the product candidates could be compromised.
● On December 31, 2024, the Company received a letter from Nasdaq stating that for the 30 consecutive business day period between November 15, 2024 to December 30, 2024 the Company’s common stock had failed to maintain a minimum closing bid price of $1.00 per share, as required for continued listing pursuant to Nasdaq Listing Rule 5550(a)(2). Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company has a grace period of 180 calendar days, or until June 30, 2025, to regain compliance with the Minimum Bid Price Requirement. To regain compliance, the closing bid price of the Company’s common stock must meet or exceed $1.00 per share for a minimum of 10 consecutive business days. In the event the Company has not regained compliance prior to the end of May 2025, the Company will have to effectuate a reverse stock split in order to regain compliance.
● On September 10, 2024, the Company received a letter from Nasdaq notifying the Company that it is no longer in compliance with the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires listed companies to maintain stockholders’ equity of at least $2,500,000. In the Company’s Quarterly Report on Form 10-Q for the period ended June 30, 2024, the Company reported stockholders’ equity of $801,434, which is below the minimum stockholders’ equity required for continued listing pursuant to Nasdaq Listing Rule 5550(b)(1). In addition, presently, the Company does not meet the alternatives of market value of listed securities or net income from continuing operations
● Our stock price may be volatile, and purchasers of our common stock could incur substantial losses.
● The future issuance of equity or of debt securities that are convertible into common stock will dilute our share capital.
● If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline.
● The restatement of our financial statements and identification of material weaknesses in our internal controls may result in additional risks and uncertainties, including regulatory, stockholder or other actions, loss of investor and counterparty confidence and negative impacts on our stock price.
● If we fail to comply with Nasdaq’s continued listing requirements, it could result in our common stock being delisted, which could adversely affect the market price and liquidity of our securities and could have other adverse effects.
RISK FACTORS
An investment in our common stock involves a high degree of risk. You should carefully consider the following risk factors and all the other information in this Annual Report before you decide to buy our common stock. If any of the following risks related to our business actually occurs, our business, financial condition, operating results, and prospects would be adversely affected. The market price of our common stock could decline due to any of these risks and uncertainties related to our business, or related to an investment in our common stock, and you may lose part or all of your investment.
Risks Related to Our Business, Financial Condition and Capital Requirements
Our consolidated financial statements are prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business; our ability to continue as a going concern is dependent upon our ability to successfully conduct clinical trials, bring a drug candidate to commercialization, generate revenues, and to raise additional equity or debt financing to fund our operations.
Our consolidated financial statements are prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has incurred losses since inception and had a net loss of approximately $9.1 million and no revenues for the year ended December 31, 2024, with working capital of approximately $0.7 million as of December 31, 2024. These conditions, and the Company’s ability to comply with such conditions, raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued.
In September 2022, the Company completed its initial public offering of common stock, generating net proceeds of approximately $10.0 million. Additionally, in January 2023, the Company entered into a securities purchase agreement with an institutional investor through which the Company sold a convertible note with a principal value of $4.3 million, along with a four-year warrant to purchase 127,260 shares of common stock, exercisable at $18.80 per share, providing the Company with approximately $3.6 million in net proceeds. As a consequence of the October 2024 Equity Financing (as defined below), the exercise price of the warrant was adjusted to $0.48 per share.
In October 2024, the Company completed an equity raise that provided $4.0 million in cash, net of placement agent fees of $0.5 million, for the issuance of 2.9 million shares/pre-funded warrants, and by 2.9 million warrants with an exercise price of $1.40 per share. In addition, in October 2024, the Company completed an offering of senior secured convertible bridge notes, receiving $790 thousand in cash. The notes have a term of one-year and were accompanied by 329,461 warrants with a weighted-average exercise price of $1.42 per share. To date, none of the above-listed warrants have been exercised. However, the Company’s existing cash resources, marketable securities and the cash received from the Company’s offerings are not expected to provide sufficient funds to support the Company’s operations and clinical trials through the next 12 months.
The capital raise has supported operations leading up to the manufacture of drug product and FDA approval of the IND for the Phase II clinical trial of Ropidoxuridine and radiation therapy in glioblastoma. The FDA recommended and the company agreed to an expansion of the clinical trial, necessitating additional capital expenditures to complete the trial. Management intends to initiate additional follow-on offerings and has submitted SBIR applications for non-dilutive NIH funding for our pre-clinical project. The ability of the Company to continue as a going concern is dependent upon our ability to successfully conduct clinical trials, bring a drug candidate to commercialization, generate revenues, and to raise additional equity or debt financing to fund our operations.
Our success is primarily dependent on the successful development, regulatory approval and commercialization of our product candidates, all of which are in the early stages of development.
Our product candidates include Ropidoxuridine, a Phase II, clinical-stage radiation sensitizer, a platform of HDAC inhibitors (SP-1-161, SP-2-225 and SP-1-303) and two preclinical, prostate cancer-oriented diagnostics assets - the PC-RAD Test, a blood test to predict clinical response to radiation therapy and the PSMA-B ligand for potential use as a theranostic agent. None of our product candidates have gained marketing approval for sale in the United States or any other country, and we cannot guarantee that we will ever have marketable products. To date, we have invested substantially all of our efforts and financial resources in the research and development and commercial planning for our current product candidate and our HDAC small molecule delivery platform. Our near-term prospects, including our ability to finance our Company and generate revenue, as well as our future growth, will depend heavily on the development, marketing approval and commercialization of our product candidates. The clinical and commercial success of product candidates will depend on a number of factors, including the following:
● building on favorable results from our Phase I clinical trial for IPdR and proceeding to Phase II and Phase III clinical trials, which may be slower or cost more than we currently anticipate;
● our ability to demonstrate safety and efficacy of our product candidates, which are ongoing determinations that are solely within the authority of the FDA;
● even if our clinical trials are completed, there can be no assurance that the FDA will agree that we have satisfactorily demonstrated safety or efficacy or that the FDA will not raise new issues regarding the design of our clinical trials;
● whether we are required by the FDA to conduct additional clinical trials to support the approval of our product candidates;
● the acceptance by the FDA of our proposed parameters for regulatory approval, including our proposed indication, endpoints and endpoint measurement tools relating to our product candidates;
● the incidence, duration and severity of adverse side effects;
● the timely receipt of necessary marketing approvals from the FDA;
● whether we are able to secure collaborations for completing the development and, if approved, commercialization of our product candidates;
● the effectiveness of our and our potential collaborators’ marketing, sales and distribution strategy and operations of product candidates that are approved;
● our success in educating physicians and patients about the benefits, administration and use of our product candidates;
● the ability of our third-party manufacturers and potential collaborators to manufacture clinical trial and commercial supplies of our product candidates to remain in good standing with regulatory bodies, and to develop, validate and maintain commercially viable manufacturing processes that are compliant with cGMP regulations;
● our ability to commercialize our product candidates, if approved for marketing;
● our ability to enforce our intellectual property rights;
● our ability to avoid third-party patent interference or patent infringement claims;
● acceptance of our product candidates as safe and effective by patients and the medical community; and
● a continued acceptable quality profile of our product candidates following approval.
Many of the risk factors detailed herein are beyond our control. Accordingly, we cannot assure you that we will ever be able to generate revenue through the sale of our product candidates. Any one of these factors or other factors discussed in this Annual Report could affect our ability to commercialize product candidates, which could impact our ability to earn sufficient revenues to transition from a developmental stage company and continue our business. If we do not obtain marketing approval of and commercialization of our product candidates, or are significantly delayed in doing so, our business will be materially harmed. We have a limited operating history and have incurred significant losses since our inception, and we anticipate that we will continue to incur losses for the foreseeable future and may never achieve or maintain profitability.
We are a clinical stage pharmaceutical company, have only recently commenced our Phase II clinical trials of our lead drug candidate, and have a limited operating history upon which you can evaluate our business and prospects. Specialty pharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. We do not currently have any product candidates in advanced clinical trials or approved for sale, and we continue to incur significant research and development and general and administrative expenses related to our operations. In addition, we have limited experience and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the specialty pharmaceutical industry. We have not generated any revenue to date and have incurred losses in each year since our founding in December 2012. Our accumulated deficit as of December 31, 2024 was $34.6 million. We expect to continue to incur significant losses for the foreseeable future. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods.
We currently have no source of product sales revenue.
We have not yet completed clinical trials and thus do not yet have commercial sales of our products and have not yet generated any revenues from commercial sales of our product candidates. Our ability to generate product revenue depends upon our ability to develop and commercialize products, including any of our current product candidates or other product candidates that we may develop, in-license or acquire in the future. We do not anticipate generating revenue from the sale of products for the foreseeable future and are reliant on our ability to raise financing through third parties, including the sale of securities. Our ability to generate future product revenue from our current or future product candidates also depends on a number of additional factors, including our ability to:
● our ability to raise funds to enable us to finance and complete research and clinical development of current and future product candidates, either directly or through collaborative relationships;
● establish and maintain supply and manufacturing relationships with third parties, and ensure adequate and legally compliant manufacturing of bulk drug substances and drug products to maintain that supply;
● obtain regulatory approval from relevant regulatory authorities in jurisdictions where we intend to market our product candidates, either directly or through collaborative relationships;
● launch and commercialize future product candidates for which we obtain marketing approval, if any, through collaborative partners;
● obtain coverage and adequate product reimbursement from third-party payors, including government payors;
● achieve market acceptance for our products, if any;
● establish, maintain and protect our intellectual property rights; and
● attract, hire and retain qualified personnel.
In addition, because of the numerous risks and uncertainties associated with clinical product development, including that our product candidates may not advance through development or achieve the endpoints of applicable clinical trials, we are unable to predict the timing or amount of any potential future product sales revenues. Our expenses also could increase beyond expectations if we decide to or are required by the FDA, or comparable foreign regulatory authorities, to perform studies or trials in addition to those that we currently anticipate. Even if we complete the development and regulatory processes described above, we anticipate incurring significant costs associated with launching and commercializing these products.
The market may not be receptive to our product candidates based on our novel therapeutic modality, and we may not generate any future revenue from the sale or licensing of product candidates.
Even if approval is obtained for a product candidate, we may not generate or sustain revenue from sales of the product due to factors such as whether the product can be sold at a competitive cost and otherwise accepted in the market. The product candidates that we are developing are based on new delivery platform therapeutic approaches (there currently is no drug which has FDA approval for indications of radiation sensitization). Market participants with significant influence over acceptance of new treatments, such as physicians and third-party payors, may not accept our delivery platform, and we may not be able to convince the medical community and third-party payors to accept and use, or to provide favorable reimbursement for, any product candidates developed by us. Market acceptance of our product candidates will depend on, among other factors:
● timing of our receipt of any marketing and commercialization approvals;
● terms of any approvals and the countries in which approvals are obtained;
● safety and efficacy of our product candidates, which are determinations solely within the authority of the FDA;
● prevalence and severity of any adverse side effects associated with our product candidates;
● warnings contained in any labeling approved by the FDA or other regulatory authority;
● convenience and ease of administration of our product candidates;
● success of our physician education programs;
● availability of adequate government and third-party payor reimbursement;
● pricing of our products, particularly as compared to alternative treatments; and
● availability of alternative effective products for indications our product candidates are intended to treat.
We will require substantial additional financing in order to obtain marketing approval of our product candidates and commercialize our product candidates; a failure to obtain this necessary capital when needed on acceptable terms, or at all, could force us to delay, limit, reduce or terminate our product development, other operations or commercialization efforts.
Since our inception, substantially all of our resources have been dedicated to the preclinical and clinical development of our HDAC small molecule delivery platform and our initial product candidate, Ropidoxuridine. Our capital needs to date have been met by contributions from existing stockholders, as well as through private offerings and IPO of our securities and our SBIR contracts. We believe that we will continue to expend substantial resources for the foreseeable future on the completion of clinical development and regulatory preparedness of our product candidates, preparations for a commercial launch of our product candidates, if approved, and development of any other current or future product candidates we may choose to further develop. These expenditures will include costs associated with research and development, conducting preclinical studies and clinical trials, obtaining marketing approvals, and, if we are not able to enter into planned collaborations, manufacturing and supply as well as marketing and selling any products approved for sale. In addition, other unanticipated costs may arise. Because the outcome of any drug development process is highly uncertain, we cannot reasonably estimate the actual amounts necessary to complete the development and commercialization of our current product candidates, if approved, or future product candidates, if any.
We believe that the proceeds we received in the $4.0 million, net of $0.5 million in placement agent fees, October 2024 offering and the $790 thousand senior secured convertible note offering, along with our existing capital resources, will not be sufficient to fund our operations one year after the date that the consolidated financial statements are issued without additional capital infusion. We anticipate we will need to seek additional funding through public or private equity or debt financings or other sources, such as through a rights offering, strategic collaborations or grants and contracts. Such financing may result in dilution to stockholders, imposition of debt covenants and repayment obligations, or other restrictions that may adversely affect our business. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans.
Our future capital requirements depend on many factors, including:
● the scope, progress, results and costs of researching and developing our current product candidates, future product candidates and conducting preclinical and clinical trials;
● the cost of commercialization activities if our current product candidates and future product candidates are approved for sale, including securing collaborative ventures for completing development of, securing marketing approval for and ultimately marketing, selling and distributing our product candidates, if approved or building a corporate infrastructure if we have to undertake these activities directly;
● our ability to establish and maintain strategic collaborations, licensing or other arrangements and the financial terms of such agreements;
● the number and characteristics of any additional product candidates we may develop or acquire;
● any product liability or other lawsuits related to our products or commenced against us;
● the expenses needed to attract and retain skilled personnel;
● the costs associated with being a public company;
● the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims, including litigation costs and the outcome of such litigation; and
● the timing, receipt and amount of sales of, or royalties on, any future approved products, if any.
Additional funds may not be available when we need them, on terms that are acceptable to us, or at all. If adequate funds are not available to us on a timely basis, we may be required to:
● delay, limit, reduce or terminate preclinical studies, clinical trials or other development activities for our current product candidates or future product candidates, if any;
● delay, limit, reduce or terminate our research and development activities; or
● delay, limit, reduce or terminate our establishment of sales and marketing capabilities or other activities that may be necessary to commercialize our current or future product candidates.
Raising additional capital may cause dilution to our existing stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.
We may seek additional capital through a combination of public and private equity offerings, debt financings, strategic collaborations and alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a stockholder. The incurrence of indebtedness would result in increased fixed payment obligations and could involve certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. If we raise additional funds through strategic collaborations and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or product candidates or grant licenses on terms unfavorable to us.
Unfavorable and/or unstable global market and economic conditions, including those caused by the ongoing conflict between the Ukraine and Russia, as well as in the Middle East, and the COVID-19 pandemic, could have serious adverse consequences on our business, financial condition and results of operations.
The global economy, including credit and financial markets, has experienced extreme volatility and disruptions as a result of the ongoing conflict between the Ukraine and Russia, as well as in the Middle East, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, increases in inflation rates and uncertainty about economic stability. Our results of operations could be adversely affected by the general conditions of the global economy and the global financial markets. In addition, any such volatility and disruptions may have adverse consequences on us or the third parties upon whom we rely. For example, in 2008, the global financial crisis caused extreme volatility and disruptions in the capital and credit markets and the COVID-19 pandemic has caused significant volatility and uncertainty in U.S. and international markets. Inflation rates, particularly in the United States, have increased recently to levels not seen in years. Increased inflation may result in increased operating costs (including our labor costs), reduced liquidity, and limitations on our ability to access credit or otherwise raise debt and equity capital. In addition, the United States Federal Reserve has raised, and may again raise, interest rates in response to concerns about inflation. Increases in interest rates, especially if coupled with reduced government spending and volatility in financial markets, may have the effect of further increasing economic uncertainty and heightening these risks, which may impact our ability to raise additional capital in the future. The March 2023 failure of Silicon Valley Bank, the pressure such failure has placed on other mid-sized banks, and its potential near- and long-term effects on the biotechnology industry and its participants such as our vendors, suppliers and investors, may also adversely affect our operations and stock price. In addition, U.S. and global markets are experiencing volatility and disruption following the escalation of geopolitical tensions and the ongoing military conflict between Russia and Ukraine, which began with a full-scale military invasion of Ukraine by Russian Troops on February 24, 2022, and the ongoing conflict between Israel and Hamas, which began on with a terrorist attack by Hamas against Israel on October 7, 2024. Although the length and impact of the ongoing military conflict is highly unpredictable, these conflicts could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain disruptions. For example, various of Russia’s actions have led to sanctions and other penalties being levied by the United States, Australia, the European Union, and other countries, as well as other public and private actors and companies, against Russia and certain other geographic areas, including agreement to remove certain Russian financial institutions from the Society for Worldwide Interbank Financial Telecommunication payment system and restrictions on imports of Russian oil, liquified natural gas and coal. Additional potential sanctions and penalties have also been proposed and/or threatened. Russian military actions and the resulting sanctions could disrupt or otherwise adversely impact our operations and the operations of third parties upon which we rely, as well as the global economy and financial markets, and lead to instability and lack of liquidity in capital markets, potentially making it more difficult for us to obtain additional funds. Related sanctions, export controls or other actions that may be initiated by nations including the United States, the European Union or Russia (e.g., potential cyberattacks, disruption of energy flows, etc.), which could adversely affect our business and/or our supply chain, our CROs, CMOs and other third parties with which we conduct business. A severe or prolonged economic downturn, inflationary environment, rising interest rates, or political unrest could result in a variety of risks to our business, including, weakened demand for our product candidates and our ability to raise additional capital when needed on acceptable terms, if at all. A weak or declining global economy could also strain our suppliers, possibly resulting in supply disruption. The extent and duration of the military action, sanctions, and resulting market disruptions are impossible to predict, but could be substantial. Any such disruptions may also magnify the impact of other risks described in this Annual Report on Form 10-K and the documents incorporated by reference herein.
Our product candidates are in the early stages of development and may fail in development or suffer delays that materially adversely affect their commercial viability.
We have no products on the market and all of our product candidates are in the early stages of development. Our ability to achieve and sustain profitability depends on obtaining regulatory approvals, including IRB approval, for and commercializing our product candidates, either alone or with third parties. Before obtaining regulatory approval for the commercial distribution of our product candidates, we or one of our collaborators must conduct extensive preclinical tests and clinical trials to demonstrate the safety and efficacy in humans of our product candidates, the final determination of which rests solely in the authority of the FDA. Preclinical testing and clinical trials are expensive, difficult to design and implement, can take many years to complete and are uncertain as to outcome. The start or end of a clinical study is often delayed or halted due to changing regulatory requirements, manufacturing challenges, required clinical trial administrative actions, slower than anticipated patient enrollment, changing standards of care, availability or prevalence of use of a comparative drug or required prior therapy, clinical outcomes or financial constraints. For instance, delays or difficulties in patient enrollment or difficulties in retaining trial participants can result in increased costs, longer development times or termination of a clinical trial. Clinical trials of a new product candidate require the enrollment of a sufficient number of patients, including patients who are suffering from the disease the product candidate is intended to treat and who meet other eligibility criteria. Rates of patient enrollment are affected by many factors, including the size of the patient population, the eligibility criteria for the clinical trial, the age and condition of the patients, the stage and severity of disease, the nature of the protocol, the proximity of patients to clinical sites and the availability of effective treatments for the relevant disease.
A product candidate can unexpectedly fail at any stage of preclinical and clinical development. The historical failure rate for product candidates is high due to scientific feasibility, lack of quality and effectiveness, changing standards of medical care and other variables. The results from preclinical testing or early clinical trials of a product candidate may not predict the results that will be obtained in later phase clinical trials of the product candidate. We, the FDA or other applicable regulatory authorities may suspend clinical trials of a product candidate at any time for various reasons, including a belief that subjects participating in such trials are being exposed to unacceptable health risks or adverse side effects. We may not have the financial resources to continue development of, or to enter into collaborations for, a product candidate if we experience any problems or other unforeseen events that delay or prevent regulatory approval of, or our ability to commercialize, product candidates, including:
● negative or inconclusive results from our clinical trials or the clinical trials of others for product candidates similar to ours, leading to a decision or requirement to conduct additional preclinical testing or clinical trials or abandon a program;
● serious and unexpected drug-related side effects experienced by participants in our clinical trials or by individuals using drugs similar to our product candidates;
● delays in submitting an Investigational New Drug application (“IND”) or delays or failure in obtaining the necessary approvals from regulators to commence a clinical trial, or a suspension or termination of a clinical trial once commenced;
● conditions imposed by the FDA or comparable foreign authorities regarding the scope or design of our clinical trials;
● delays in enrolling research subjects in clinical trials;
● high drop-out rates of research subjects;
● greater than anticipated clinical trial costs;
● poor effectiveness of our product candidates during clinical trials;
● unfavorable FDA or other regulatory agency inspection and review of a clinical trial site;
● failure of our third-party contractors or investigators to comply with regulatory requirements or otherwise meet their contractual obligations in a timely manner, or at all;
● delays and changes in regulatory requirements, policy and guidelines, including the imposition of additional regulatory oversight around clinical testing generally or with respect to our technology in particular; or
● varying interpretations of data by the FDA and similar foreign regulatory agencies.
If third parties on which we depend to conduct our preclinical studies, or any future clinical trials, do not perform as contractually required, fail to satisfy regulatory or legal requirements or miss expected deadlines, our development program could be delayed with materially adverse effects on our business, financial condition, results of operations and prospects.
We are relying on third party collaborators to conduct our efficacy clinical trials for Ropidoxuridine and plan to rely on third party clinical investigators, CROs, clinical data management organizations and consultants to design, conduct, supervise and monitor preclinical studies of our product candidates and will do the same for any clinical trials. Because we plan to largely rely on third parties and do not have the ability to conduct preclinical studies or clinical trials independently, we have less control over the timing, quality and other aspects of preclinical studies and clinical trials than we would if we conducted them on our own. These investigators, CROs, and consultants are not our employees and we have limited control over the amount of time and resources that they dedicate to our programs. These third parties may have contractual relationships with other entities, some of which may be our competitors, which may draw time and resources from our programs. The third parties with whom we contract might not be diligent, careful or timely in conducting our preclinical studies or clinical trials, resulting in the preclinical studies or clinical trials being delayed or unsuccessful.
If we cannot contract with acceptable third parties on commercially reasonable terms, or at all, or if these third parties do not carry out their contractual duties, satisfy legal and regulatory requirements for the conduct of preclinical studies or clinical trials or meet expected deadlines, our clinical development programs could be delayed and otherwise adversely affected. In all events, we are responsible for ensuring that each of our preclinical studies and clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. The FDA requires clinical trials to be conducted in accordance with good clinical practices, including for conducting, recording and reporting the results of preclinical studies and clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of clinical trial participants are protected. Our reliance on third parties that we do not control does not relieve us of these responsibilities and requirements. Any such event could have a material adverse effect on our business, financial condition, results of operations and/or prospects.
Because we rely on third party manufacturing and supply partners, our supply of research and development, and preclinical and clinical development materials, may become limited or interrupted or may not be of satisfactory quantity or quality.
We rely on third party supply and manufacturing partners to supply the materials and components for, and manufacture, our research and development, preclinical and clinical trial drug supplies. We do not own manufacturing facilities or supply sources for such components and materials. There can be no assurance that our supply of research and development, preclinical and clinical development drugs and other materials will not be limited, interrupted, restricted in certain geographic regions or of satisfactory quality or continue to be available at acceptable prices. In particular, any replacement of any drug product formulation manufacturer we may use could require significant effort and expertise in the event there are a limited number of qualified replacements for a particular product candidate.
The manufacturing process for a product candidate is subject to FDA and foreign regulatory authority review. Suppliers and manufacturers must meet applicable manufacturing requirements and undergo rigorous facility and process validation tests required by regulatory authorities in order to comply with regulatory standards, such as cGMP. In the event that any of our suppliers or manufacturers fail to comply with such requirements or to perform its obligations to us in relation to quality, timing or otherwise, or if our supply of components or other materials becomes limited or interrupted for other reasons, we may be forced to manufacture the materials ourselves, for which we currently do not have the capabilities or resources, or enter into an agreement with another third party, which we may not be able to do on reasonable terms, if at all. In some cases, the technical skills or technology required to manufacture our product candidates may be unique or proprietary to the original manufacturer, and we may have difficulty, or there may be contractual restrictions prohibiting us from, transferring such skills or technology to another third party and a feasible alternative may not exist. These factors would increase our reliance on such manufacturer or require us to obtain a license from such manufacturer in order to have another third party manufacture our product candidates. If we are required to change manufacturers for any reason, we will be required to verify that the new manufacturer maintains facilities and procedures that comply with quality standards and with all applicable regulations and guidelines. The delays associated with the verification of a new manufacturer could negatively affect our ability to develop product candidates in a timely manner or within budget.
We expect to continue to rely on third party manufacturers if we receive regulatory approval for any product candidate. To the extent that we have existing or future manufacturing arrangements with third parties, we will depend on these third parties to perform their obligations in a timely manner consistent with contractual and regulatory requirements, including those related to quality control and assurance. If we are unable to obtain or maintain third-party manufacturing for product candidates, or to do so on commercially reasonable terms, we may not be able to fully develop and commercialize our product candidates. Our or a third party’s failure to execute on our manufacturing requirements could adversely affect our business in a number of ways, including:
● an inability to initiate or continue clinical trials of product candidates under development;
● delay in submitting regulatory applications, or receiving regulatory approvals, for product candidates;
● loss of the cooperation of a collaborator;
● subjecting our product candidates to additional inspections by regulatory authorities;
● requirements to cease distribution or to recall batches of our product candidates; and
● in the event of approval to market and commercialize a product candidate, an inability to meet commercial demands for our products.
We may be unsuccessful in engaging in strategic transactions which could adversely affect our ability to develop and commercialize product candidates, impact our cash position, increase our expense and present significant distractions to our management.
From time to time, we may consider strategic transactions, such as collaborations, acquisitions of companies, asset purchases and out- or in- licensing of product candidates or technologies. In particular, we will evaluate and, if strategically attractive, seek to enter into additional collaborations, including with major biotechnology or pharmaceutical companies to complete development and marketing of our product candidates, if approved. The competition for collaborators is intense, and the negotiation process is time-consuming and complex. Any proposed collaboration may be on terms that are not optimal for us, and we may not be able to maintain any new or existing collaboration if, for example, development or approval of a product candidate is delayed, sales of an approved product candidate do not meet expectations or the collaborator terminates the collaboration. Any such collaboration, or other strategic transaction, may require us to incur non-recurring or other charges, increase our near- and long-term expenditures and pose significant integration or implementation challenges or disrupt our management or business. These transactions would entail numerous operational and financial risks, including exposure to unknown liabilities, disruption of our business and diversion of our management’s time and attention in order to manage a collaboration or develop acquired products, product candidates or technologies, incurrence of substantial debt or dilutive issuances of equity securities to pay transaction consideration or costs, higher than expected collaboration, acquisition or integration costs, write-downs of assets or goodwill or impairment charges, increased amortization expenses, difficulty and cost in facilitating the collaboration or combining the operations and personnel of any acquired business, impairment of relationships with key suppliers, manufacturers or customers of any acquired business due to changes in management and ownership and the inability to retain key employees of any acquired business. Accordingly, although there can be no assurance that we will undertake or successfully complete any transactions of the nature described above, any transactions that we do complete may be subject to the foregoing or other risks and have a material adverse effect on our business, results of operations, financial condition and prospects. Conversely, any failure to enter into any collaboration or other strategic transaction that would be beneficial to us could delay the development and potential commercialization of our product candidates and have a negative impact on the competitiveness of any product candidate that reaches market.
We face competition from entities that have developed or may develop product candidates for our target disease indications, including companies developing novel treatments and technology platforms based on modalities and technology similar to ours. If these companies develop technologies or product candidates more rapidly than we do or their technologies, including delivery technologies, are more effective, our ability to develop and commercialize product candidates may be adversely affected.
The development and commercialization of drugs is highly competitive. We compete with a variety of multinational pharmaceutical companies and specialized biotechnology companies, as well as with universities and other research institutions which are developing new technology. Our competitors have developed, are developing or will develop product candidates and processes competitive with our product candidates. Competitive therapeutic treatments include those that have already been approved and accepted by the medical community and any new treatments that enter the market. We believe that a significant number of products are currently under development, and may become commercially available in the future, for the treatment of conditions for which we may try to develop product candidates.
Many of our competitors have significantly greater financial, technical, manufacturing, marketing, sales and supply resources or experience than we have. If we obtain approval for any product candidate, we will face competition based on many different factors, including the quality and effectiveness of our products, the ease with which our products can be administered and the extent to which patients accept relatively new routes of administration, the timing and scope of regulatory approvals for these products, the availability and cost of manufacturing, marketing and sales capabilities, price, reimbursement coverage and patent position. Competing products could present superior treatment alternatives, including by being more effective, safer, less expensive or marketed and sold more effectively than any products we may develop. Competitive products may make any products we develop obsolete or noncompetitive before we recover the expense of developing and commercializing our product candidates. Such competitors could also recruit our employees, which could negatively impact our level of expertise and our ability to execute our business plan.
Any inability to attract and retain qualified key management and technical personnel would impair our ability to implement our business plan.
Our success largely depends on the continued service of certain key management and other specialized personnel, including Anatoly Dritschilo, M.D., our Chief Executive Officer, Timothy Lorber, our Chief Financial Officer, Mira Jung, Ph.D., our Chief Scientific Officer, Michael Vander Hoek, our Vice President Operations and Regulatory, and Peter Dritschilo, our President and Chief Operating Officer. The loss of one or more members of our management team or other key employees or advisors could delay our research and development programs and materially harm our business, financial condition, results of operations and prospects. The relationships that our key managers have cultivated within our industry make us particularly dependent upon their continued employment with us. We are dependent on the continued service of our technical personnel because of the highly technical nature of our product candidates and technologies and the specialized nature of the regulatory approval process. Because our management team and key employees are not obligated to provide us with continued service, they could terminate their employment with us at any time without penalty. We do not maintain key person life insurance policies on any of our management team members or key employees. Our future success will depend in large part on our continued ability to attract and retain other highly qualified scientific, technical and management personnel, as well as personnel with expertise in clinical testing, manufacturing, governmental regulation and commercialization. We face competition for personnel from other companies, universities, public and private research institutions, government entities and other organizations.
If our product candidates advance into Phase II and Phase III clinical trials, we may experience difficulties in managing our growth and expanding our operations.
As our product candidates enter into and advance through preclinical studies and any clinical trials, we will need to expand our development, regulatory and manufacturing capabilities or contract with other organizations to provide these capabilities for us. In the future, we expect to have to manage additional relationships with collaborators or partners, suppliers and other organizations. Our ability to manage our operations and future growth will require us to continue to improve our operational, financial and management controls, reporting systems and procedures. We may not be able to implement improvements to our management information and control systems in an efficient or timely manner and may discover deficiencies in existing systems and controls.
If any of our product candidates are approved for marketing and commercialization and we are unable to develop sales, marketing and distribution capabilities on our own or enter into agreements with third parties to perform these functions on acceptable terms, we will be unable to commercialize any such future products.
We currently have no sales, marketing or distribution capabilities or experience. If any of our product candidates is approved, we plan to enter into collaborations with third parties to sell, market and distribute our products. In the alternative, we would have to develop internal sales, marketing and distribution capabilities to commercialize any approved product, which would be expensive and time-consuming, or, as is more likely, enter into collaborations with third parties to perform these services. If we rely on third parties with sales, marketing and distribution capabilities to market our products or decide to co-promote products with collaborators, we will need to establish and maintain marketing and distribution arrangements with third parties, and there can be no assurance that we will be able to enter into such arrangements on acceptable terms, if, at all. In entering into third-party marketing or distribution arrangements, any revenue we receive will depend upon the efforts of the third parties and there can be no assurance that such third parties will establish adequate sales and distribution capabilities or be successful in gaining market acceptance of any approved product. If we decide to market our products directly, we will need to commit significant financial and managerial resources to develop a marketing and sales force with technical expertise and supporting distribution, administration and compliance capabilities. If we are not able to commercialize any product approved in the future, either on our own or through third parties, our business, financial condition, results of operations and prospects could be materially adversely affected.
If we fail to comply with U.S. and foreign regulatory requirements, regulatory authorities could limit or withdraw any marketing or commercialization approvals we may receive and subject us to other penalties that could materially harm our business.
Even if we receive marketing and commercialization approval of a product candidate, there can be no assurance we will not be subject to future or continuing regulatory review, including in relation to adverse patient experiences with the product and clinical results that are reported after a product is made commercially available, both in the U.S. and any foreign jurisdiction in which we seek regulatory approval. The FDA has significant post-market authority, including the authority to require labeling changes based on new safety information and to require post-market studies or clinical trials to evaluate safety risks related to the use of a product or to require withdrawal of the product from the market. The FDA also has the authority to require a risk evaluation and mitigation strategies (“REMS”) plan after approval, which may impose further requirements or restrictions on the distribution or use of an approved drug. The manufacturer and manufacturing facilities we use to make a future product, if any, will also be subject to periodic review and inspection by the FDA and other regulatory agencies, including for continued compliance with CGMP requirements. The discovery of any new or previously unknown problems with our third-party manufacturers, manufacturing processes or facilities may result in restrictions on the product, manufacturer or facility, including withdrawal of the product from the market. If we rely on third-party manufacturers, we will not have control over compliance with applicable rules and regulations by such manufacturers. Any product promotion and advertising will also be subject to regulatory requirements and continuing regulatory review. If we or our collaborators, manufacturers or service providers fail to comply with applicable continuing regulatory requirements in the U.S. or foreign jurisdictions in which we seek to market our products, we or they may be subject to, among other things, fines, warning letters, holds on clinical trials, refusal by the FDA to approve pending applications or supplements to approved applications, suspension or withdrawal of regulatory approval, product recalls and seizures, refusal to permit the import or export of products, operating restrictions, injunction, civil penalties and criminal prosecution.
Our business entails a significant risk of product liability and our ability to obtain sufficient insurance coverage could have a material effect on our business, financial condition, results of operations or prospects.
Our business exposes us to significant product liability risks inherent in the development, testing, manufacturing and marketing of therapeutic treatments. Product liability claims could delay or prevent completion of our development programs. If we succeed in marketing products, such claims could result in an FDA investigation of the quality and effectiveness of our products, our manufacturing processes and facilities or our marketing programs and potentially a recall of our products or more serious enforcement action, limitations on the approved indications for which they may be used or suspension or withdrawal of approvals. Regardless of the merits or eventual outcome, liability claims may also result in decreased demand for our products, injury to our reputation, costs to defend the related litigation, a diversion of management’s time and our resources, substantial monetary awards to trial participants or patients and a decline in our stock price. We currently have product liability insurance that we believe is appropriate for our stage of development and may need to obtain higher levels prior to marketing any of our product candidates. Any insurance we have or may obtain may not provide sufficient coverage against potential liabilities. Furthermore, clinical trial and product liability insurance is becoming increasingly expensive. As a result, we may be unable to obtain sufficient insurance at a reasonable cost to protect us against losses caused by product liability claims that could have a material adverse effect on our business.
Our employees, principal investigators, CROs and consultants may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.
We are exposed to the risk that our employees, principal investigators, CROs and consultants may engage in fraud, other misconduct or illegal activity. Misconduct by these parties could include intentional failures to comply with FDA regulations, provide accurate information to the FDA, comply with manufacturing standards we may establish, comply with federal and state healthcare fraud and abuse laws and regulations, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. While we make an effort to maintain strict work processes and oversight of our employees, contractors and consultants, any misconduct could expose us to liability through the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. Furthermore, it is not always possible to identify and deter such misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.
Our internal computer systems, or those of our CROs or other contractors or consultants, may fail or suffer security breaches, which could result in a material disruption of our product development programs.
We have established a cybersecurity subcommittee, consisting of two independent directors and two officers of the Company (the “Cybersecurity Subcommittee”). Our Cybersecurity Subcommittee held its first meeting in January 2024 to (i) identify risks associated with cybersecurity, (ii) design guidance on cybersecurity, (iii) design plans to mitigate potential damages that may be caused by cyber issues, and (iv) provide training plan to employees. Additionally, in April 2024, our Cybersecurity Subcommittee requested our employees to complete a series of cybersecurity related trainings.
Despite the implementation of cyber security measures, our internal computer systems and those of our CROs and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. Such events could cause interruptions of our operations. For example, the loss of preclinical data or data from any future clinical trial involving our product candidates could result in delays in our development and regulatory filing efforts and significantly increase our costs. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the development of our product candidates could be delayed.
Our proprietary information, or that of our customers, suppliers and business partners, may be lost or we may suffer security breaches.
In the ordinary course of our business, we collect and store sensitive data, including intellectual property, clinical trial data, our proprietary business information and that of our customers, suppliers and business partners, and personally identifiable information of our customers, clinical trial subjects and employees, in our data centers and on our networks. The secure processing, maintenance and transmission of this information is critical to our operations. Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. Although to our knowledge we have not experienced any such material security breach to date, any such breach could compromise our network, or the networks of our CROs or other third-party service providers, and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, regulatory penalties, disrupt our operations, damage our reputation, and cause a loss of confidence in our products and our ability to conduct clinical trials, which could adversely affect our business and reputation and lead to delays in gaining regulatory approvals for our drugs. Although we maintain business interruption insurance coverage, our insurance might not cover all losses from any future breaches of our systems.
Failure of our information technology systems could significantly disrupt the operation of our business.
Our business increasingly depends on the use of information technologies, which means that certain key areas such as research and development, production and sales are to a large extent dependent on our information systems or those of third-party providers. Our ability to execute our business plan and to comply with regulatory requirements with respect to data control and data integrity, depends, in part, on the continued and uninterrupted performance of our information technology systems, or IT systems and the IT systems supplied by third-party service providers. These systems are vulnerable to damage from a variety of sources, including telecommunications or network failures, malicious human acts and natural disasters. Moreover, despite network security and backup measures, some of our servers are potentially vulnerable to physical or electronic break-ins, computer viruses and similar disruptive problems. Despite the precautionary measures we and our third-party service providers have taken to prevent unanticipated problems that could affect our IT systems, sustained or repeated system failures or problems arising during the upgrade of any of our IT systems that interrupt our ability to generate and maintain data, and in particular to operate our proprietary technology platform, could adversely affect our ability to operate our business.
If we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected.
Our research, development and manufacturing involve the use of hazardous materials and various chemicals. We maintain quantities of various flammable and toxic chemicals in our facilities in Gaithersburg, Maryland that are required for our research, development and manufacturing activities. We are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these hazardous materials. We believe our procedures for storing, handling and disposing these materials in our Gaithersburg facilities comply with the relevant guidelines of Gaithersburg, the State of Maryland and the Occupational Safety and Health Administration of the U.S. Department of Labor. Although we believe that our safety procedures for handling and disposing of these materials comply with the standards mandated by applicable regulations, the risk of accidental contamination or injury from these materials cannot be eliminated. If an accident occurs, we could be held liable for resulting damages, which could be substantial. We are also subject to numerous environmental, health and workplace safety laws and regulations, including those governing laboratory procedures, exposure to blood-borne pathogens and the handling of animals and biohazardous materials. Although we maintain workers’ compensation insurance to cover us for costs and expenses, we may incur due to injuries to our employees resulting from the use of these materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological or hazardous materials. Additional federal, state and local laws and regulations affecting our operations may be adopted in the future. We may incur substantial costs to comply with, and substantial fines or penalties if we violate any of these laws or regulations.
Our information technology systems could face serious disruptions that could adversely affect our business.
Our information technology and other internal infrastructure systems, including corporate firewalls, servers, leased lines and connection to the Internet, face the risk of systemic failure that could disrupt our operations. A significant disruption in the availability of our information technology and other internal infrastructure systems could cause interruptions in our collaborations with our partners and delays in our research and development work.
Changes in accounting rules and regulations, or interpretations thereof, could result in unfavorable accounting charges or require us to change our compensation policies.
Accounting methods and policies for pharmaceutical companies, including policies governing revenue recognition, research and development and related expenses and accounting for stock-based compensation are subject to review, interpretation and guidance from relevant accounting authorities, including the SEC. Changes to accounting methods or policies, or interpretations thereof, may require us to reclassify, restate or otherwise change or revise our financial statements, including those contained in this Annual Report.
Risks Related to Our Intellectual Property
If we are not able to obtain and enforce patent protection for our technologies or product candidates, development and commercialization of our product candidates may be adversely affected.
Our success depends in part on our ability to obtain and maintain patents and other forms of intellectual property rights, including in-licenses of intellectual property rights of others, for our product candidates, methods used to manufacture our product candidates and methods for treating patients using our product candidates, as well as our ability to preserve our trade secrets, to prevent third parties from infringing upon our proprietary rights and to operate without infringing upon the proprietary rights of others. As of the date of this Annual Report, we have filed six patent applications with the U.S. Patent and Trademark Office (the “USPTO”) with respect to various aspects of our HDAC inhibitor small molecule delivery platforms and Ropidoxuridine, our lead product candidate. However, we may not be able to apply for patents on certain aspects of our product candidates or delivery technologies in a timely fashion or at all. To date, four U.S. patents and eighteen European patents have been granted. There is no guarantee that any of our pending patent applications will result in issued or granted patents, that any of our issued, granted or licensed patents will not later be found to be invalid or unenforceable or that any issued, granted or licensed patents will include claims that are sufficiently broad to cover our product candidates or delivery technologies or to provide meaningful protection from our competitors. Moreover, the patent position of specialty pharmaceutical companies can be highly uncertain because it involves complex legal and factual questions. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our current and future proprietary technology and product candidates are covered by valid and enforceable patents or are effectively maintained as trade secrets. If third parties disclose or misappropriate our proprietary rights, it may materially and adversely impact our position in the market.
The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other requirements during the patent process. There are situations in which noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have been the case. The standards applied by the USPTO and foreign patent offices in granting patents are not always applied uniformly or predictably. For example, there is no uniform worldwide policy regarding patentable subject matter or the scope of claims allowable in pharmaceutical patents. As such, we do not know the degree of future protection that we will have on our proprietary products and technology. While we will endeavor to try to protect our product candidates with intellectual property rights such as patents, as appropriate, the process of obtaining patents is time-consuming, expensive and sometimes unpredictable.
We may decide for business reasons to no longer pursue or to abandon certain intellectual property rights in the U.S. or elsewhere, including due to non-cooperation of inventors or owners of such intellectual property, prior art, or scope of protection, or for other reasons.
Once granted, patents may remain open to opposition, interference, re-examination, post-grant review, inter partes review, nullification or derivation action in court or before patent offices or similar proceedings for a given period after allowance or grant, during which time third parties can raise objections against such initial grant. In the course of such proceedings, which may continue for a protracted period of time, the patent owner may be compelled to limit the scope of the allowed or granted claims thus attacked, or may lose the allowed or granted claims altogether. In addition, there can be no assurance that:
● others will not or may not be able to make, use or sell compounds that are the same as or similar to our product candidates but that are not covered by the claims of the patents that we own or license;
● we or our licensors, collaborators or any future collaborators are the first to make the inventions covered by each of our issued patents and pending patent applications that we own or license;
● we or our licensors, collaborators or any future collaborators are the first to file patent applications covering certain aspects of our inventions;
● others will not independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual property rights;
● A third party may not challenge our patents and, if challenged, a court may not hold that our patents are valid, enforceable and infringed;
● any issued patents that we own or have licensed will provide us with any competitive advantages, or will not be challenged by third parties;
● we may develop additional proprietary technologies that are patentable;
● the patents of others will not have an adverse effect on our business; and
● our competitors do not conduct research and development activities in countries where we do not have enforceable patent rights and then use the information learned from such activities to develop competitive products for sale in our major commercial markets.
We intend to license patent rights from third-party owners or licensees. If such owners or licensees do not properly or successfully obtain, maintain or enforce the patents underlying such licenses, or if they retain or license to others any competing rights, our competitive position and business prospects may be adversely affected. We may not be able to protect our intellectual property rights throughout the world.
Obtaining a valid and enforceable issued or granted patent covering our technology in the U.S. and worldwide can be extremely costly. In jurisdictions where we have not obtained patent protection, competitors may use our technology to develop their own products and further, may export otherwise infringing products to territories where we have patent protection, but where it is more difficult to enforce a patent as compared to the U.S. Competitor products may compete with our future products in jurisdictions where we do not have issued or granted patents or where our issued or granted patent claims or other intellectual property rights are not sufficient to prevent competitor activities in these jurisdictions. The legal systems of certain countries, particularly certain developing countries, make it difficult to enforce patents and such countries may not recognize other types of intellectual property protection, particularly that relating to biopharmaceuticals. This could make it difficult for us to prevent the infringement of patents or marketing of competing products in violation of our proprietary rights generally in certain jurisdictions. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial cost and divert our efforts and attention from other aspects of our business.
We generally file a provisional patent application first (a priority filing) at the USPTO. A U.S. utility application and international application under the Patent Cooperation Treaty (PCT) are usually filed within twelve months after the priority filing. Based on the PCT filing, national and regional patent applications may be filed in the European Union, Japan, Australia and Canada and other countries. We have so far not filed for patent protection in all national and regional jurisdictions where such protection may be available. In addition, we may decide to abandon national and regional patent applications before grant. Finally, the grant proceeding of each national or regional patent is an independent proceeding which may lead to situations in which applications might in some jurisdictions be refused by the relevant registration authorities, while granted by others. It is also quite common that depending on the country, various scopes of patent protection may be granted on the same product candidate or technology. The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws in the U.S., and many companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. If we or our licensors encounter difficulties in protecting, or are otherwise precluded from effectively protecting, the intellectual property rights important for our business in such jurisdictions, the value of these rights may be diminished, and we may face additional competition from others in those jurisdictions. Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we or any of our licensors are forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position in the relevant jurisdiction may be impaired and our business and results of operations may be adversely affected.
We or our licensors, or any future collaborators or a strategic partners may become subject to third party claims or litigation alleging infringement of patents or other proprietary rights or seeking to invalidate patents or other proprietary rights, and we may need to resort to litigation to protect or enforce our patents or other proprietary rights, all of which could be costly, time consuming, delay or prevent the development and commercialization of our product candidates, or put our patents and other proprietary rights at risk.
We or our licensors, or any future collaborators or strategic partners may be subject to third-party claims for infringement or misappropriation of patent or other proprietary rights. We are generally obligated under our license or collaboration agreements to indemnify and hold harmless our licensors or collaborator for damages arising from intellectual property infringement by us. If we or our licensors, or any future collaborators or strategic partners are found to infringe a third-party patent or other intellectual property rights, we could be required to pay damages, potentially including treble damages, if we are found to have willfully infringed. In addition, we or our licensors, collaborators or any future strategic partners may choose to seek, or be required to seek, a license from a third party, which may not be available on acceptable terms, if at all. Even if a license can be obtained on acceptable terms, the rights may be non-exclusive, which could give our competitors access to the same technology or intellectual property rights licensed to us. If we fail to obtain a required license, we or our collaborator, or any future collaborator, may be unable to effectively market product candidates based on our technology, which could limit our ability to generate revenue or achieve profitability and possibly prevent us from generating revenue sufficient to sustain our operations. In addition, we may find it necessary to pursue claims or initiate lawsuits to protect or enforce our patent or other intellectual property rights. The cost to us in defending or initiating any litigation or other proceeding relating to patent or other proprietary rights, even if resolved in our favor, could be substantial, and litigation would divert our management’s attention. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could delay our research and development efforts and limit our ability to continue our operations.
If we were to initiate legal proceedings against a third party to enforce a patent covering one of our products or our technology, the defendant could counterclaim that our patent is invalid or unenforceable. In patent litigation in the U.S., defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, for example, lack of novelty, obviousness or non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO, or made a misleading statement, during prosecution. The outcome following legal assertions of invalidity and unenforceability during patent litigation is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on one or more of our products or certain aspects of our platform technology. Such a loss of patent protection could have a material adverse impact on our business. Patents and other intellectual property rights also will not protect our technology if competitors design around our protected technology without legally infringing our patents or other intellectual property rights.
Intellectual property rights of third parties could adversely affect our ability to commercialize our product candidates, and we might be required to litigate or obtain licenses from third parties in order to develop or market our product candidates. Such litigation or licenses could be costly or not available on commercially reasonable terms.
Our competitive position may suffer if patents issued to third parties or other third-party intellectual property rights cover our products or elements thereof, or our manufacture or uses relevant to our development plans. In such cases, we may not be in a position to develop or commercialize products or product candidates unless we successfully pursue litigation to nullify or invalidate the third-party intellectual property right concerned, or enter into a license agreement with the intellectual property right holder, if available on commercially reasonable terms.
Third party intellectual property right holders may also actively bring infringement claims against us. We cannot guarantee that we will be able to successfully settle or otherwise resolve such infringement claims. If we are unable to successfully settle future claims on terms acceptable to us, we may be required to engage in or continue costly, unpredictable and time-consuming litigation and may be prevented from or experience substantial delays in marketing our products. If we fail in any such dispute, in addition to being forced to pay damages, we may be temporarily or permanently prohibited from commercializing any of our product candidates that are held to be infringing. We might, if possible, also be forced to redesign product candidates so that we no longer infringe the third-party intellectual property rights. Any of these events, even if we were ultimately to prevail, could require us to divert substantial financial and management resources that we would otherwise be able to devote to our business.
If we fail to comply with our obligations under any license, collaboration or other agreements, we may be required to pay damages and could lose intellectual property rights that are necessary for developing and protecting our product candidates and delivery technologies or we could lose certain rights to grant sublicenses.
Our current licenses impose, and any future licenses we enter into are likely to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution and enforcement, and other obligations on us. If we breach any of these obligations, or use the intellectual property licensed to us in an unauthorized manner, we may be required to pay damages and the licensor may have the right to terminate the license, which could result in us being unable to develop, manufacture and sell products that are covered by the licensed technology or enable a competitor to gain access to the licensed technology. Moreover, our licensors may own or control intellectual property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit, that we are infringing or otherwise violating the licensor’s rights. In addition, while we cannot currently determine the amount of the royalty obligations we would be required to pay on sales of future products, if any, the amounts may be significant. The amount of our future royalty obligations will depend on the technology and intellectual property we use in products that we aim to develop and commercialize, if any. Therefore, even if we are able to develop and commercialize products, we may be unable to achieve or maintain profitability.
If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.
In addition to seeking patent protection for certain aspects of our product candidates and delivery technologies, we also consider trade secrets, including confidential and unpatented know-how important to the maintenance of our competitive position. We protect trade secrets and confidential and unpatented know-how, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to such knowledge, such as our employees, corporate collaborators, outside scientific collaborators, CROs, contract manufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants that obligate them to maintain confidentiality and assign their inventions to us. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time- consuming, and the outcome is unpredictable. In addition, some courts in the U.S. and certain foreign jurisdictions are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be harmed.
We may be subject to claims that we or our employees or consultants have wrongfully used or disclosed alleged trade secrets of our employees’ or consultants’ former employers or their clients. These claims may be costly to defend and if we do not successfully do so, we may be required to pay monetary damages and may lose valuable intellectual property rights or personnel.
Many of our employees were previously employed at universities or biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although no claims against us are currently pending, 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 their former employers. Litigation may be necessary to defend against these claims. If we fail in defending such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. A loss of key research personnel or their work product could hamper our ability to commercialize, or prevent us from commercializing, our product candidates, which could severely harm our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.
If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.
Our trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names or may be forced to stop using these names, which we need for name recognition by potential partners or customers in our markets of interest. If we are unable to establish name recognition based on our trademarks and trade names, we may not be able to effectively compete and our business may be adversely affected.
Risks Related to Government Regulation and Product Approvals
We may be unable to obtain U.S. or foreign regulatory approval and, as a result, unable to commercialize our product candidates.
Our product candidates are subject to extensive governmental regulations relating to, among other things, research, testing, development, manufacturing, safety, efficacy, approval, recordkeeping, reporting, labeling, storage, packaging, advertising and promotion, pricing, marketing and distribution of drugs. Rigorous preclinical testing and clinical trials and an extensive regulatory approval process are required to be completed in the U.S. and in many foreign jurisdictions before a new drug can be marketed. Satisfaction of these and other regulatory requirements is costly, time-consuming, uncertain and subject to unanticipated delays. It is possible that none of the product candidates we may develop will obtain the regulatory approvals necessary for us or our collaborators to begin selling them.
We have very limited experience in conducting and managing the clinical trials necessary to obtain regulatory approvals, including approval by the FDA. The time required to obtain FDA and other approvals is unpredictable but typically takes many years following the commencement of clinical trials, depending upon the type, complexity and novelty of the product candidate. The standards that the FDA and its foreign counterparts use when regulating us are not always applied predictably or uniformly and can change. Any analysis we perform of data from preclinical and clinical activities is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. We may also encounter unexpected delays or increased costs due to new government regulations, for example, from future legislation or administrative action, or from changes in FDA policy during the period of product development, clinical trials and FDA regulatory review. It is impossible to predict whether legislative changes will be enacted, or whether FDA or foreign regulations, guidance or interpretations will be changed, or what the impact of such changes, if any, may be.
Any delay or failure in obtaining required approvals could have a material adverse effect on our ability to generate revenues from the particular product candidate for which we are seeking approval. Furthermore, any regulatory approval to market a product may be subject to limitations on the approved uses for which we may market the product or the labeling or other restrictions. In addition, the FDA has the authority to require a Risk Evaluation and Mitigation Strategy (REMS) plan as part of an NDA or biologics license application (BLA) or after approval, which may impose further requirements or restrictions on the distribution or use of an approved drug or biologic, such as limiting prescribing to certain physicians or medical centers that have undergone specialized training, limiting treatment to patients who meet certain safe-use criteria and requiring treated patients to enroll in a registry. These limitations and restrictions may limit the size of the market for the product and affect reimbursement by third-party payors.
If we or our collaborators, manufacturers or service providers fail to comply with healthcare laws and regulations, we or they could be subject to enforcement actions, which could affect our ability to develop, market and sell our products and may harm our reputation.
We and our collaborators are subject to federal, state, and foreign healthcare laws and regulations pertaining to fraud and abuse and patients’ rights. These laws and regulations include:
● the U.S. federal healthcare program anti-kickback law, which prohibits, among other things, persons from soliciting, receiving or providing remuneration, directly or indirectly, to induce either the referral of an individual for a healthcare item or service, or the purchasing or ordering of an item or service, for which payment may be made under a federal healthcare program such as Medicare or Medicaid;
● the U.S. federal false claims law, which prohibits, among other things, individuals or entities from knowingly presenting or causing to be presented, claims for payment by government funded programs such as Medicare or Medicaid that are false or fraudulent, and which may apply to us by virtue of statements and representations made to customers or third parties;
● the U.S. federal Health Insurance Portability and Accountability Act (HIPAA) and Health Information Technology for Economic and Clinical Health (HITECH) Act, which prohibit executing a scheme to defraud healthcare programs, impose requirements relating to the privacy, security, and transmission of individually identifiable health information, and require notification to affected individuals and regulatory authorities of certain breaches of security of individually identifiable health information;
● the federal Open Payments regulations under the National Physician Payment Transparency Program have been issued under the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, and will require that manufacturers of pharmaceutical and biological drugs covered by Medicare, Medicaid, and Children’s Health Insurance Programs report all consulting fees, travel reimbursements, research grants, and other payments or gifts with values over $10 made to physicians and teaching hospitals; and
● state laws comparable to each of the above federal laws, such as, for example, anti-kickback and false claims laws applicable to commercial insurers and other non-federal payors, requirements for mandatory corporate regulatory compliance programs, and laws relating to patient data privacy and security.
If our operations are found to be in violation of any such requirements, we may be subject to penalties, including civil or criminal penalties, monetary damages, the curtailment or restructuring of our operations, loss of eligibility to obtain approvals from the FDA, or exclusion from participation in government contracting, healthcare reimbursement or other government programs, including Medicare and Medicaid, any of which could adversely our financial results. Although effective compliance programs can mitigate the risk of investigation and prosecution for violations of these laws, these risks cannot be entirely eliminated. Any action against us for an alleged or suspected violation could cause us to incur significant legal expenses and could divert our management’s attention from the operation of our business, even if our defense is successful. In addition, achieving and sustaining compliance with applicable laws and regulations may be costly to us in terms of money, time, and resources.
If we or our collaborators, manufacturers or service providers fail to comply with applicable federal, state, or foreign laws or regulations, we could be subject to enforcement actions, which could affect our ability to develop, market and sell our products successfully and could harm our reputation and lead to reduced acceptance of our products by the market. These enforcement actions include, among others:
● adverse regulatory inspection findings;
● warning letters;
● voluntary or mandatory product recalls or public notification or medical product safety alerts to healthcare professionals;
● restrictions on, or prohibitions against, marketing our products;
● restrictions on, or prohibitions against, importation or exportation of our products;
● suspension of review or refusal to approve pending applications or supplements to approved applications;
● exclusion from participation in government-funded healthcare programs;
● exclusion from eligibility for the award of government contracts for our products;
● suspension or withdrawal of product approvals;
● product seizures;
● injunctions; and
● civil and criminal penalties and fines.
Any drugs we develop may become subject to unfavorable pricing regulations, third-party reimbursement practices or healthcare reform initiatives, which may harm our business.
The regulations that govern marketing approvals, pricing and reimbursement for new drugs vary widely from country to country. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. Although we intend to monitor these regulations, our programs are currently in the early stages of development and we will not be able to assess the impact of price regulations for a number of years. As a result, we might obtain regulatory approval for a product in a particular country, but then be subject to price regulations that delay our commercial launch of the product and negatively impact the revenues we are able to generate from the sale of the product in that country.
Our ability to commercialize any products also will depend in part on the extent to which reimbursement for these products and related treatments will be available from government health administration authorities, private health insurers and other organizations. Even if we succeed in bringing one or more products to the market, these products may not be considered cost-effective, and the amount reimbursed for any products may be insufficient to allow us to sell our products on a competitive basis. Because our programs are in the early stages of development, we are unable at this time to determine their cost effectiveness or the likely level or method of reimbursement. Increasingly, the third-party payors who reimburse patients or healthcare providers, such as government and private insurance plans, are requiring that drug companies provide them with predetermined discounts from list prices and are seeking to reduce the prices charged or the amounts reimbursed for pharmaceutical products. If the price we are able to charge for any products we develop, or the reimbursement provided for such products, is inadequate in light of our development and other costs, our return on investment could be adversely affected.
Our current product candidates will need to be administered under the supervision of a physician on an outpatient basis. Under currently applicable U.S. law, certain drugs that are not usually self-administered (including injectable drugs) may be eligible for coverage under the Medicare Part B program if:
● they are incident to a physician’s services;
● they are reasonable and necessary for the diagnosis or treatment of the illness or injury for which they are administered according to accepted standards of medical practice; and
● they have been approved by the FDA and meet other requirements of the statute.
There may be significant delays in obtaining coverage for newly-approved drugs, and coverage may be more limited than the purposes for which the drug is approved by the FDA. Moreover, eligibility for coverage does not imply that any drug will be reimbursed in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim payments for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement may be based on payments allowed for lower- cost drugs that are already reimbursed, may be incorporated into existing payments for other services and may reflect budgetary constraints or imperfections in Medicare data. Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the U.S. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement rates. Our inability to promptly obtain coverage and adequate reimbursement rates from both government-funded and private payors for new drugs that we develop and for which we obtain regulatory approval could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our financial condition.
We believe that the efforts of governments and third-party payors to contain or reduce the cost of healthcare and legislative and regulatory proposals to broaden the availability of healthcare will continue to affect the business and financial condition of pharmaceutical and biopharmaceutical companies. A number of legislative and regulatory changes in the healthcare system in the U.S. and other major healthcare markets have been proposed in recent years, and such efforts have expanded substantially in recent years. These developments have included prescription drug benefit legislation that was enacted and took effect in January 2006, healthcare reform legislation enacted by certain states, and Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act (the “ACA”), a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending and enhance remedies against fraud and abuse. The ACA also contains provisions that will affect companies in the pharmaceutical industry and other healthcare related industries by imposing additional costs and changes to business practices. Provisions affecting pharmaceutical companies include the following:
● mandatory rebates for drugs sold into the Medicaid program have been increased, and the rebate requirement has been extended to drugs used in risk-based Medicaid managed care plans;
● the 340B Drug Pricing Program under the Public Health Services Act has been extended to require mandatory discounts for drug products sold to certain critical access hospitals, cancer hospitals and other covered entities;
● pharmaceutical companies are required to offer discounts on brand-name drugs to patients who fall within the Medicare Part D coverage gap, commonly referred to as the “Donut Hole”; and
● pharmaceutical companies are required to pay an annual non-tax deductible fee to the federal government based on each company’s market share of prior year total sales of branded products to certain federal healthcare programs, such as Medicare, Medicaid, Department of Veterans Affairs and Department of Defense. Since we expect our branded pharmaceutical sales to constitute a small portion of the total federal health program pharmaceutical market, we do not expect this annual assessment to have a material impact on our financial condition.
Moreover, we cannot predict what healthcare reform initiatives may be adopted in the future. Further federal and state legislative and regulatory developments are likely, and we expect ongoing initiatives in the U.S. to increase pressure on drug pricing. Such reforms could have an adverse effect on anticipated revenues from product candidates that we may develop and for which we may obtain regulatory approval and may affect our overall financial condition and ability to develop product candidates.
Our ability to obtain services, reimbursement or funding from the federal government, including the ability to obtain grants from the NIH, may be impacted by possible reductions in federal spending or changes in regulations or the regulatory environment.
U.S. federal government agencies currently face potentially significant spending reductions. Under the Budget Control Act of 2011, the failure of Congress to enact deficit reduction measures of at least $1.2 trillion for the years 2013 through 2021 triggered automatic cuts to most federal programs. These cuts would include aggregate reductions to Medicare payments to providers of up to two percent per fiscal year, starting in 2013. Under the American Taxpayer Relief Act of 2012, which was enacted on January 1, 2013, the imposition of these automatic cuts was delayed until March 1, 2013. Certain of these automatic cuts have been implemented and the federal government has implemented, and may be poised to implement, additional budget cuts. The full impact on our business of such cuts is uncertain. If federal spending is reduced, anticipated budgetary shortfalls may also impact the ability of relevant agencies, such as the FDA or the NIH to continue to function at current levels. Amounts allocated to federal grants and contracts may be reduced or eliminated. These reductions may also impact the ability of relevant agencies to timely review and approve drug research and development, manufacturing, and marketing activities, which may delay our ability to develop, market and sell any products we may develop.
If any of our product candidates receives marketing approval and we or others later identify undesirable side effects caused by the product candidate, our ability to market and derive revenue from the product candidates could be compromised.
In the event that any of our product candidates receive regulatory approval and we or others identify undesirable side effects caused by one of our products, any of the following adverse events could occur, which could result in the loss of significant revenue to us and materially and adversely affect our results of operations and business:
● regulatory authorities may withdraw their approval of the product or seize the product;
● we may be required to recall the product or change the way the product is administered to patients;
● additional restrictions may be imposed on the marketing of the particular product or the manufacturing processes for the product or any component thereof;
● we may be subject to fines, injunctions or the imposition of civil or criminal penalties;
● regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication;
● we may be required to create a Medication Guide outlining the risks of such side effects for distribution to patients;
● we could be sued and held liable for harm caused to patients;
● the product may become less competitive; and
● our reputation.
Risks Related to our Common Stock
If we fail to comply with the continued listing requirements of The Nasdaq Stock Market, it could result in our common stock being delisted, which could adversely affect the market price and liquidity of our securities and could have other adverse effects.
On December 31, 2024, the Company received a letter from Nasdaq stating that for the 30 consecutive business day period between November 15, 2024 to December 30, 2024 the Company’s common stock had failed to maintain a Minimum Bid Price Requirement of $1.00 per share, as required for continued listing on The Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2). Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company has a grace period of 180 calendar days, or until June 30, 2025, to regain compliance with the Minimum Bid Price Requirement. To regain compliance, the closing bid price of the Company’s common stock must meet or exceed $1.00 per share for a minimum of 10 consecutive business days.
Pursuant the new Nadsaq Rule 5810, which does not allow for more than one reverse split in any 12 month period, because Shuttle Pharma completed a 1-for-8 reverse stock split in August 2024, the Company must regain compliance with the Minimum Bid Price Requirement by no later than June 30, 2025, as the Company is not eligible for an additional 180-day compliance period. As a result, if the Company’s price per share does not organically increase to $1.00 or more prior to the end of May 2025, the Company will be obligated, upon obtaining stockholder approval, to complete a reverse split in order to regain compliance with the Nasdaq Listing Requirements. If the Company cannot regain compliance prior to June 30, 2025, Nasdaq will provide the Company with notice that its common stock will be subject to delisting. At that time, the Company may appeal Nasdaq’s delisting determination to a Nasdaq Hearings Panel.
Nasdaq’s notice to the Company of noncompliance has no immediate effect on the listing of the Company’s common stock and its common stock will continue to be listed on The Nasdaq Capital Market under the symbol “SHPH.” There can be no assurance that the Company will regain compliance with the Minimum Bid Price Requirement or maintain compliance with any of the other Nasdaq continued listing requirements. The Company will continue to monitor the closing bid price of its common stock and may, if appropriate, consider available options to regain compliance with the Minimum Bid Price Requirement.
In addition, on September 10, 2024, the Company received a letter from Nasdaq, notifying the Company that it is no longer in compliance with the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires listed companies to maintain stockholders’ equity of at least $2.5 million. In the Company’s Quarterly Report on Form 10-Q for the period ended June 30, 2024, the Company reported stockholders’ equity of $801,434, which is below the minimum stockholders’ equity required for continued listing pursuant to Nasdaq Listing Rule 5550(b)(1). In addition, presently, the Company does not meet the alternatives of market value of listed securities or net income from continuing operations.
Nasdaq’s notice has no immediate effect on the listing of the Company’s securities on the Nasdaq Capital Market. Nasdaq provided the Company with 45 calendar days, or until October 25, 2024, to submit a plan to regain compliance with the minimum stockholders’ equity standard.
On October 15, 2024, the Company submitted a plan to Nasdaq to regain compliance, which was accepted by Nasdaq. As a result, the Company now has until March 10, 2025 to complete a follow on equity raise to bring the Company’s stockholders’ equity above the minimum requirement of $2.5 million. While the Company is presently seeking additional funding, and intends to pursue a follow-on offering in the coming weeks, there is no guarantee that the Company will be able to complete such equity raise or otherwise be able to regain compliance within the requisite time period. If the Company does not regain compliance, Nasdaq will provide notice to the Company that the Company’s securities will become subject to delisting. In that event, the Company will have an opportunity to appeal Nasdaq’s decision to a hearings panel.
While our Company’s management is working to improve our internal controls and procedures, at present management has determined that our internal controls were deemed to be inadequate, which could cause our financial reporting to be unreliable and lead to misinformation being disseminated to the public.
Our management is responsible for establishing and maintaining adequate internal control over financial reporting. As defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), internal control over financial reporting is a process designed by, or under the supervision of, the principal executive and principal financial officer and effected by the board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:
● pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;
● provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and/or directors of the Company; and
● provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.
We are required to include in our Annual Report on Form 10-K a report of management on the effectiveness of our internal control over financial reporting. We expect to incur additional expenses and diversion of management’s time as a result of performing the system and process evaluation, testing and remediation required in order to comply with the management certification requirements.
Presently, we have identified financial reporting internal control weaknesses relating to segregation of duties, information technology general controls and various accounting processes. While we have improved our organizational capabilities, we still may not have a sufficient number of employees to segregate responsibilities and may be unable to afford further enhancements to our staff or engaging outside consultants or professionals further to fully mitigate these internal control deficiencies. During the course of our testing, we may identify other deficiencies that we may not be able to timely remediate. If we cannot provide reliable financial reports or prevent fraud, our business and operating results could be harmed, investors could lose confidence in our reported financial information, and the trading price of our common stock, if a market ever develops, could drop significantly.
The Jobs Act has reduced the information that we are required to disclose.
Under the Jobs Act, the information that we will be required to disclose has been reduced in a number of ways.
As a company that had gross revenues of less than $1.235 billion during the Company’s last fiscal year, the Company is an “emerging growth company,” as defined in the Jobs Act (an “EGC”). We will retain that status until the earliest of (a) the last day of the fiscal year which we have total annual gross revenues of $1.235 billion (as indexed for inflation in the manner set forth in the Jobs Act) or more; (b) the last day of the fiscal year of following the fifth anniversary of the date of the first sale of the common stock pursuant to an effective registration statement under the Securities Act; (c) the date on which we have, during the previous three year period, issued more than $1,000,000,000 in non-convertible debt; or (d) the date on which we are deemed to be a “large accelerated filer,” as defined in Rule 12b-2 under the Exchange Act or any successor thereto. As an EGC, the Company is relieved from the following:
● The Company is excluded from Section 404(b) of Sarbanes-Oxley Act (“Sarbanes-Oxley”), which otherwise would have required the Company’s auditors to attest to and report on the Company’s internal control over financial reporting. The JOBS Act also amended Section 103(a)(3) of Sarbanes-Oxley to provide that (i) any new rules adopted by the PCAOB requiring mandatory audit firm rotation or changes to the auditor’s report to include auditor discussion and analysis (in the event the PCAOB adopts an auditor rotation requirement) will not apply to an audit of an EGC; and (ii) any other future rules adopted by the PCAOB will not apply to the Company’s audits unless the SEC determines otherwise.
● The Jobs Act amended Section 7(a) of the Securities Act to provide that the Company need not present more than two years of audited financial statements in an initial public offering registration statement and in any other registration statement, need not present selected financial data pursuant to Item 301 of Regulation S-K for any period prior to the earliest audited period presented in connection with such initial public offering. In addition, the Company is not required to comply with any new or revised financial accounting standard until such date as a private company (i.e., a company that is not an “issuer” as defined by Section 2(a) of Sarbanes-Oxley) is required to comply with such new or revised accounting standard. Corresponding changes have been made to the Exchange Act, which relates to periodic reporting requirements, which would be applicable if the Company were required to comply with them.
● As long as we are an EGC, we may comply with Item 402 of Regulation S-K, which requires extensive quantitative and qualitative disclosure regarding executive compensation, by disclosing the more limited information required of a “smaller reporting company.”
● The Jobs Act will also exempt us from the following additional compensation-related disclosure provisions that were imposed on U.S. public companies pursuant to the Dodd-Frank Act: (i) the advisory vote on executive compensation required by Section 14A(a) of the Exchange Act; (ii) the requirements of Section 14A(b) of the Exchange Act relating to stockholders advisory votes on “golden parachute” compensation; (iii) the requirements of Section 14(i) of the Exchange Act as to disclosure relating to the relationship between executive compensation and our financial performance; and (iv) the requirement of Section 953(b)(1) of the Dodd-Frank Act, which requires disclosure as to the relationship between the compensation of our chief executive officer and median employee pay.
Our stock price may be volatile, and purchasers of our common stock could incur substantial losses.
Since commencement of trading on Nasdaq, our stock price has been extremely volatile. As a result of this volatility, investors may not be able to sell their common stock at or above the price when they purchased our common stock. The market price for our common stock may be influenced by many factors, including the other risks described in this section of this Annual Report entitled “Risk Factors” and the following:
● the success of competitive products or technologies;
● results of preclinical and clinical studies of our product candidates, or those of our competitors, our existing collaborator or any future collaborators;
● regulatory or legal developments in the U.S. and other countries, especially changes in laws or regulations applicable to our products;
● introductions and announcements of new products by us, our commercialization partners, or our competitors, and the timing of these introductions or announcements;
● actions taken by regulatory agencies with respect to our products, clinical studies, manufacturing process or sales and marketing terms;
● actual or anticipated variations in our financial results or those of companies that are perceived to be similar to us;
● the success of our efforts to acquire or in-license additional technologies, products or product candidates;
● developments concerning our collaborations, including but not limited to those with our sources of manufacturing supply and our commercialization partners;
● announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments;
● developments or disputes concerning patents or other proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our products;
● our ability or inability to raise additional capital and the terms on which we raise it;
● the recruitment or departure of key personnel;
● changes in the structure of healthcare payment systems;
● market conditions in the pharmaceutical and biotechnology sectors;
● actual or anticipated changes in earnings estimates or changes in stock market analyst recommendations regarding our common stock, other comparable companies or our industry generally;
● our failure or the failure of our competitors to meet analysts’ projections or guidance that we or our competitors may give to the market;
● fluctuations in the valuation of companies perceived by investors to be comparable to us;
● announcement and expectation of additional financing efforts;
● speculation in the press or investment community;
● trading volume of our common stock;
● sales of our common stock by us or our stockholders;
● the concentrated ownership of our common stock;
● changes in accounting principles;
● terrorist acts, acts of war or periods of widespread civil unrest;
● natural disasters and other calamities; and
● general economic, industry and market conditions.
In addition, the stock markets in general, and the markets for pharmaceutical stocks, in particular, have experienced extreme volatility that has been often unrelated to the operating performance of the issuer. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance.
The future issuance of equity or of debt securities that are convertible into common stock will dilute our share capital.
We may choose to raise additional capital in the future, depending on market conditions, strategic considerations and operational requirements. To the extent that additional capital is raised through the issuance of shares or other securities convertible into shares of our common stock, our stockholders will be diluted. Future issuances of our common stock or other equity securities, or the perception that such sales may occur, could adversely affect the trading price of our common stock and impair our ability to raise capital through future offerings of shares or equity securities. No prediction can be made as to the effect, if any, that future sales of common stock or the availability of common stock for future sales will have on the trading price of our common stock.
If we fail to maintain applicable listing requirements, Nasdaq may delist our common stock from trading, in which case the liquidity and market price of our common stock could decline.
We cannot assure you that we will be able to meet the continued listing standards of Nasdaq in the future. If we fail to comply with the applicable listing standards, including the requirement that we regain compliance with the $2.5 million stockholders’ equity requirement and the Minimum Bid Price Requirement, and Nasdaq delists our common stock, we and our stockholders could face significant material adverse consequences, including:
● a limited availability of market quotations for shares of our common stock;
● reduced liquidity for our common stock;
● a determination that our common stock is “penny stock,” which would require brokers trading in our common stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for shares of our common stock;
● a limited amount of news about us and analyst coverage of us; and
● a decreased ability for us to issue additional equity securities or obtain additional equity or debt financing in the future.
The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Because our common stock is listed on Nasdaq, such securities will be deemed covered securities. Although the states will be preempted from regulating the sale of our securities, the federal statute does allow states to investigate companies if there is a suspicion of fraud and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in a particular case. Further, if we were no longer listed on Nasdaq, our securities would not be covered securities and we would be subject to regulations in each state in which we offer our securities.
Because our management has broad discretion over the use of the net proceeds we have received, or will receive, from our equity and/or debt follow-on offerings, you may not agree with how we use them and the proceeds may not be invested successfully.
We intend to use the net proceeds to us from any follow-on offerings to fund preclinical and clinical trials of product candidates, Ropidoxuridine and new formulations of Ropidoxuridine with Tipiracil, O-18 containing molecules for proton radiation sensitization, continued HDAC technology platform development, working capital and general corporate purposes, including the costs of operating as a public company, as well as potential acquisition or in-licensing activities. Therefore, our management has broad discretion as to the use of the IPO proceeds and proceeds from our subsequent private placements or follow-on offerings. Accordingly, you will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that the proceeds will be invested in a way that does not yield a favorable, or any, return for our Company.
If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline.
The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not currently have and may never obtain research coverage by securities and industry analysts. If no or few securities or industry analysts commence coverage of us, the trading price for our stock would be negatively impacted. In the event we obtain securities or industry analyst coverage, if any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model, our intellectual property or our stock performance, or if our target studies and operating results fail to meet the expectations of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.
Our board of directors has the authority, without stockholder approval, to issue preferred stock with terms that may not be beneficial to holders of our common stock and such issuance could potentially adversely affect stockholders’ voting power and perpetuate their control over us.
Our Certificate of Incorporation, as amended to date, allows us to issue shares of preferred stock without any vote or further action by our stockholders. Our board of directors has the authority to fix and determine the relative rights and preferences of any preferred stock. As a result, our board of directors could authorize the issuance of a series of preferred stock that would grant to holders the preferred right to our assets upon liquidation, the right to receive dividend payments before dividends are distributed to the holders of common stock and the right to the redemption of the shares, together with a premium, prior to the redemption of shares of our common stock. These rights and preferences could negatively affect the holders of our common stock.
The ability of our executive officers and directors, who are our principal stockholders, to control our business may limit or eliminate the ability of minority stockholders to influence corporate affairs.
Our executive officers and directors, who are our principal stockholders, own approximately 22.78% of our issued and outstanding common stock. Accordingly, they may be able to effectively control the election of directors, as well as all other matters requiring stockholder approval. The interests of our principal stockholders may differ from the interests of other stockholders with respect to the issuance of shares, business transactions with or sales to other companies, selection of other directors and other business decisions. The minority stockholders have no way of overriding decisions made by our principal stockholders. This level of control may also have an adverse impact on the market value of our shares because our principal stockholders may institute or undertake transactions, policies or programs that result in losses and may not take any steps to increase our visibility in the financial community and/or may sell sufficient numbers of shares to significantly decrease our price per share.
Our Certificate of Incorporation and Bylaws, each as amended to date, provide for indemnification of officers and directors at the expense of the Company and limit their liability that may result in a major cost to us and hurt the interests of our stockholders because corporate resources may be expended for the benefit of officers and/or directors.
Our Certificate of Incorporation and Bylaws, each as amended to date, provide for the indemnification of our officers and directors. We have been advised that, in the opinion of the SEC, indemnification for liabilities arising under federal securities laws is against public policy as expressed in the Securities Act and is therefore, unenforceable.
Our Certificate of Incorporation, as amended to date, provides that disputes must be resolved in the Court of Chancery of the State of Delaware, except for cases brought under the Securities Act or Exchange Act.
Our Certificate of Incorporation, as amended to date, provides that the Court of Chancery in the State of Delaware will be the exclusive forum for dispute resolution for certain enumerated actions, excluding any actions brought under the Securities Act or Exchange Act, or unless the Company consents in writing to an alternative jurisdiction. This exclusive forum selection clause may cause inconvenience of our stockholders or other stakeholders, should they need to bring suit against the Company for an action other than one arising under the Securities Act or Exchange Act.
We do not expect to pay cash dividends in the foreseeable future.
We have never paid cash dividends on our common stock. We do not expect to pay cash dividends on our common stock at any time in the foreseeable future. The future payment of dividends on our common stock directly depends upon our future earnings, capital requirements, financial requirements and other factors that our board of directors will consider. Since we do not anticipate paying cash dividends on our common stock, return on your investment, if any, will depend solely on an increase, if any, in the market value of our common stock.
Provisions in our amended and restated certificate of incorporation, as amended, and bylaws, as amended, as well as Delaware law, might discourage, delay or prevent a change of control of our company or changes in our management and, therefore, depress the market price of our common stock.
Our Certificate of Incorporation and Bylaws, each as amended to date, and bylaws contain provisions that could depress the market price of our common stock by acting to discourage, delay, or prevent a change in control of our company or changes in our management that the stockholders of our company may deem advantageous. These provisions, among other things:
● permit the board of directors to establish the number of directors;
● provide that directors may only be removed “for cause” and only with the approval of 66 2/3 percent of our stockholders;
● require super-majority voting to amend some provisions in our Certificate of Incorporation and Bylaws;
● authorize the issuance of “blank check” preferred stock that our board of directors could use to implement a stockholder rights plan (also known as a “poison pill”);
● eliminate the ability of our stockholders to call special meetings of stockholders;
● prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;
● provide that the board of directors is expressly authorized to make, alter or repeal our bylaws; and
● establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by stockholders at annual stockholder meetings.
In addition, Section 203 of the Delaware General Corporation Law may discourage, delay or prevent a change in control of our company. Section 203 imposes certain restrictions on merger, business combinations and other transactions between us and holders of 15% or more of our common stock.
The restatement of our consolidated financial statements and identification of material weaknesses in our internal controls may result in additional risks and uncertainties, including regulatory, stockholder or other actions, loss of investor and counterparty confidence and negative impacts on our stock price.
On July 10, 2024, the Audit Committee and Company management, after consultation and discussion with our independent registered public accounting firm, concluded that certain of our previously issued audited consolidated financial statements and unaudited consolidated financial statements need to be restated and should no longer be relied on for the reasons described in the Current Report on Form 8-K dated July 10, 2024, and in “Explanatory Note” preceding Part I, Item 1 of the Form 10-K/A we filed on September 4, 2024 (the “Form 10-K/A”) and Note 2 to the Consolidated Financial Statements under Part II, Item 8 of the Form 10-K/A.
The accounting errors impacted the Company’s consolidated financial statements for the year ended December 31, 2022. These errors further resulted in an impact to the Company’s consolidated balance sheet for the year ended December 31, 2023 and the unaudited condensed consolidated balance sheet as of and for the periods ended March 31, 2023, June 30, 2023 and September 30, 2023, specific to Additional Paid In Capital and Accumulated Deficit. Additionally, the restatement constituted an event of default under the terms of one of the Company’s financing arrangements that was subsequently waived but required additional cash collateral from the Company.
In addition, in connection with the restatement of the previously issued financial statements for the fiscal year ended December 31, 2023 and December 31, 2022, and fiscal quarter ended March 31, 2024 (the “Affected Periods”), management identified certain material weaknesses in our internal control over financial reporting. Although we are taking remediation measures, including having hired a new Chief Financial Officer during the second quarter of 2024 to bolster the Company’s internal technical accounting and financial reporting experience and provide bandwidth for the prior Chief Financial Officer to focus on the Company’s expanding clinical trials, we can give no assurance that the measures we have taken, are taking and plan to take in the future will remediate the material weaknesses identified or that any additional material weaknesses or restatements of financial results will not arise in the future due to a failure to implement and maintain adequate internal control over financial reporting. In addition, even if we are successful in strengthening our controls and procedures, in the future those controls and procedures may not be adequate to prevent or identify irregularities or errors or to facilitate the fair presentation of our consolidated financial statements.
As a result of the restatement and associated non-reliance on the previously issued financial statements for the Affected Periods and the identified material weakness, we have become subject to a number of additional costs and risks, including unanticipated costs for accounting and legal fees in connection with or related to the restatement and the ongoing process of remediating the material weaknesses. We could also be subject to regulatory, stockholder or other actions in connection with the restatement and/or the material weaknesses, which would, regardless of the outcome, consume management’s time and attention and may result in additional legal, accounting and other costs. If such proceedings arise and we do not prevail in such proceedings, we could be required to pay damages or settlement costs. In addition, the restatement and related matters could impair our reputation or could cause our stockholders or other counterparties to lose confidence in us. Any of these occurrences could adversely affect our business, financial condition, liquidity and results of operations.
If we fail to comply with the continued listing requirements of Nasdaq, it could result in our common stock being delisted, which could adversely affect the market price and liquidity of our securities and could have other adverse effects.
On December 31, 2024, the Company received a letter from the Nasdaq Listing Qualifications Staff of The Nasdaq Stock Market LLC stating that for the 30 consecutive business day period between November 15, 2024 to December 30, 2024 the Company’s common stock had failed to maintain a minimum closing bid price of $1.00 per share, as required for continued listing on The Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”). Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company has an initial period of 180 calendar days, or until June 30, 2025, to regain compliance with the Minimum Bid Price Requirement. To regain compliance, the closing bid price of the Company’s common stock must meet or exceed $1.00 per share for a minimum of 10 consecutive business days.
On September 10, 2024, we received a letter from Nasdaq notifying the Company that it is no longer in compliance with the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires listed companies to maintain stockholders’ equity of at least $2.5 million. In addition, presently, the Company does not meet the alternatives of market value of listed securities or net income from continuing operations.
Our plan of regain compliance has been accepted by Nasdaq and now we have 180 days, or until March 10, 2025, to regain compliance. However, there can be no assurance that the Company will be able to regain compliance and maintain its listing on the Nasdaq Capital Market. If the Company fails to regain compliance during the extended compliance period, or if the Company fails to satisfy another Nasdaq requirement for continued listing, Nasdaq could provide notice that the Company’s securities will become subject to delisting. In that event, the Company will have an opportunity to appeal Nasdaq’s decision to a hearings panel.
While we aim to regain compliance with Nasdaq’s stockholders equity requirement, we nonetheless run the risk that our stock may be delisted if we fail to comply with Nasdaq listing requirements. In the event our common stock is delisted, we may seek to have our common stock quoted on an over-the-counter marketplace, such as on the OTCQX. The OTCQX is not a stock exchange, and if our common stock trades on the OTCQX rather than a securities exchange, there may be significantly less trading volume and analyst coverage of, and significantly less investor interest in, our common stock, which may lead to lower trading prices for our common stock.
Any potential delisting of our common stock from the Nasdaq may have materially adverse consequences to our stockholders, including:
● a reduced market price and liquidity with respect to our shares of common stock, which could make our ability to raise new investment capital more difficult;
● limited dissemination of market price of our common stock;
● limited news coverage;
● limited interest by investors in our common stock;
● volatility of the prices of our common stock, due to low trading volume;
● our common stock being considered a “penny stock,” which would result in broker-dealers participating in sales of our common stock being subject to the regulations set forth in Rules 15g-2 through 15g-9 promulgated under the Exchange Act;
● increased difficulty in selling our common stock in certain states due to “blue sky” restrictions; and
● limited ability to issue additional securities or to secure additional financing.
Sales of substantial amounts of our securities in the public market could depress the market price of our common stock.
Our common stock is listed for trading on the Nasdaq Capital Market. If our stockholders sell substantial amounts of our common stock in the public market, or the market perceives that such sales may occur, the market price of our securities could fall and we may be unable to sell our securities in the future.
Our securities may experience extreme price and volume fluctuations, which could lead to costly litigation for us and make an investment in us less appealing.
The market price of our common stock may fluctuate substantially due to a variety of factors, including:
● the status and results of our clinical trials for our product candidate;
● our ability to fund and complete our study and, if such study provides data supporting an FDA submission, our ability to apply for and obtain clearance from the FDA;
● our ability to remain a going concern;
● our ability to maintain our Nasdaq listing;
● our business strategy and plans;
● the potential market for our product candidate, if approved for sale in the U.S.;
● new regulatory pronouncements and changes in regulatory guidelines and timing of regulatory approvals;
● general and industry-specific economic conditions;
● variations in our quarterly financial and operating results, including the rate at which we incur negative cash flow in future periods;
● additions to or departures of our key personnel;
● changes in market valuations of other companies that operate in our business segments or in our industry;
● lack of trading liquidity;
● if our product is approved and becomes available for us to sell in the U.S., whether we ultimately achieve profitability or not;
● changes in accounting principles; and
● general market conditions, economic and other external factors.
The market prices of the securities of early-stage companies, particularly companies like ours that are seeking to obtain regulatory approval of their product candidate and do not yet generate operating revenue, have been highly volatile and are likely to remain highly volatile in the future. This volatility has often been unrelated to the operating performance of particular companies. In the past, companies that experience volatility in the market price of their securities have often faced securities class action litigation. Whether or not meritorious, litigation brought against us could result in substantial costs, divert our management’s attention and resources and harm our financial condition and results of operations.
Although we have no preferred stock outstanding as of the date hereof and we have currently no intention to issue any preferred stock, our common stockholders could be adversely affected by the issuance by us of preferred stock in the future, if any.
Our certificate of incorporation does not restrict our ability to offer one or more series of preferred stock, any or all of which could rank equally with or have preferences over our common stock as to dividend payments, voting rights, rights upon liquidation or other types of rights. Our board of directors has the authority, without further action by the stockholders, to issue shares of preferred stock in one or more series and to fix the rights, preferences and the number of shares constituting any series or the designation of such series. In the case our board of directors decides to issue any preferred stock, we would have no obligation to consider the specific interests of the holders of common stock in creating any such series of preferred stock or engaging in any such offering or transaction. Our creation of any series of preferred stock or our engaging in any such offering or transaction could have a material adverse effect on holders of our common stock.
Trading of our common stock may be limited, making it difficult for our stockholders to sell their shares, and future sales of common stock could reduce our stock price.
Our common stock currently trades on Nasdaq under the ticker “SHPH.” The liquidity of our common stock may be limited, including in terms of the number of shares that can be bought and sold at a given price and reduction in security analysts’ and the media’s coverage of us, if any. These factors may result in different prices for our common stock than might otherwise be obtained in a more liquid market and could also result in a larger spread between the bid and asked prices for our common stock. In addition, in the absence of a large market capitalization, our common stock is less liquid than the stock of companies with broader public ownership, and, as a result, the trading prices of our common stock may be more volatile. In the absence of an active public trading market, an investor may be unable to liquidate his/her investment in our common stock. Trading of a relatively small volume of our common stock may have a greater impact on the trading price of our stock. We cannot predict the prices at which our common stock will trade in the future, if at all.
FINRA sales practice requirements may limit a stockholder’s ability to buy and sell our securities.
Effective June 30, 2020, the SEC implemented Regulation Best Interest requiring that “A broker, dealer, or a natural person who is an associated person of a broker or dealer, when making a recommendation of any securities transaction or investment strategy involving securities (including account recommendations) to a retail customer, shall act in the best interest of the retail customer at the time the recommendation is made, without placing the financial or other interest of the broker, dealer, or natural person who is an associated person of a broker or dealer making the recommendation ahead of the interest of the retail customer.” This is a significantly higher standard for broker-dealers to recommend securities to retail customers than before under FINRA “suitability rules.” FINRA suitability rules do still apply to institutional investors and require that in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending securities to their customers, broker-dealers must make reasonable efforts to obtain information about the customer’s financial status, tax status, investment objectives and other information, and for retail customers determine the investment is in the customer’s “best interest” and meet other SEC requirements. As a result, fewer broker-dealers may be willing to make a market in our common stock, reducing a stockholder’s ability to resell shares of our common stock.

Facilities
Our corporate headquarters are presently located in 401 Professional Drive, Suite 260, Gaithersburg, Maryland 20879 where we lease approximately 2,109 square feet of office and laboratory space (together, the “Laboratory Space”), which includes shared access to office space and reception services. Our research and development activities are performed in the Laboratory Space. We entered into a lease for the new Laboratory Space on June 1, 2023, and the lease has an initial term of 5.25 years and an option to extend for an additional three years, with a monthly rent of $7,206 per month, subject to increase at the rate of 3% per year. All of such space is leased from a non-affiliated third party.
We believe that the above facilities are adequate for our current needs and have sufficient laboratory space to house additional scientists as we grow.

Recent Sales of Unregistered Securities
During the past three years, we effected the following transactions in reliance upon exemptions from registration under the Securities Act:
On February 8, 2022 and March 11, 2022, the Company sold to certain accredited investors $365,000 and $225,000, respectively, in 6% convertible notes (the “Notes”), which bore 6% interest, were repayable on December 31, 2024, and converted automatically into shares of common stock or, in the event that units were sold in the offering, units, at a conversion price of $32.00 per unit upon closing of our IPO. Such notes were sold to accredited investors pursuant to an exemption from registration under Rule 506(b) of the Securities Act. Boustead Securities LLC acted as placement agent and received compensation of (i) $36,500 in cash and warrants to purchase 10% of the total number of shares issuable upon conversion of the Convertible Notes, exercisable at the conversion price of the Convertible Notes for the February offering and (ii) $22,750 in cash and warrants to purchase 10% of the total number of shares issuable upon conversion of the Convertible Notes, exercisable at the conversion price of the Convertible Notes for the March offering.
Effective March 30, 2022, the Company issued a total of 839 shares (105 shares on a post-reverse split basis) of common stock (the “Issuance”) to some 23 existing shareholders in satisfaction of certain interest that had accrued as the result of an inaccurate conversion of convertible notes in our 2018 share exchange. The Issuance satisfied in full all interest owed or otherwise accruing as the result of the inaccurate conversion. Such issuance was made in accordance with Rule 506(b) of the Securities Act.
On August 1, 2022, in conjunction with entering into three loan agreements for a total of $125,000, which were repayable following consummation of our IPO, we issued warrants to purchase a total of 6,250 shares of our common stock, exercisable at $20.00 per share. Such warrants were sold to three accredited investors pursuant to an exemption from registration under Rule 506(b) of the Securities Act. Boustead Securities LLC acted as placement agent and received warrants to purchase 625 shares of common stock exercisable at $20.00 per share, equal to 10% of the value of the note offering, and $12,500 in cash compensation.
On January 11, 2023, we entered into a stock purchase agreement (the “SPA”) with the Alto Opportunity Master Fund, SPC - Segregated Master Portfolio B, a Cayman entity (the “Investor”), pursuant to which the Company sold to the Investor a $4.3 million convertible note (the “Convertible Note”) and warrant (the “Warrant”) to purchase 127,260 shares of common stock of the Company, in exchange for gross proceeds of $4.0 million Investment Amount. The Convertible Note amortizes on a monthly basis and the Company can make such monthly amortization payments in cash or, subject to certain equity conditions, in registered shares of common stock or a combination thereof. For equity repayment, the Convertible Note is convertible into shares of common stock at price per share equal to the lower of (i) $18.80 (ii) 90% of the three lowest daily VWAPs of the 15 trading days prior to the payment date or (iii) 90% of the VWAP of the trading day prior to payment date. The Convertible Note is repayable over 26 months and bears interest at the rate of 5% per annum. The Warrant is exercisable for four years from the date of closing and is exercisable at $0.48 per share. In the event the Investor exercises the Warrant in full, such exercise would result in additional gross proceeds to the Company of approximately $0.1 million.
On May 10, 2023, we entered into an amendment agreement to the SPA (the “Amendment Agreement”). Under the Amendment Agreement, the Company and the Investor amended the transaction documents as follows: (i) amended and restated Section 2 of the Warrant so as to remove a provision that would have potentially required an adjustment to the number of warrant shares exercisable under the Warrant, (ii) stipulated that the Company would obtain majority shareholder approval to issue up to an additional $10 million Subsequent Notes and Subsequent Warrants equal to 42.5% of the outstanding principal value of the Subsequent Notes, which Subsequent Note and Subsequent Warrant would be sold to the Investor on substantially the same terms as the existing Convertible Note and Warrant (each as amended by the Amendment Agreement) and upon conversion and/or exercise would cause the potential issuance of in excess of 19.9% of the Company’s issued and outstanding stock, (iii) that, upon obtaining majority stockholder approval, the Company would file a Schedule 14C related to such potential issuance of the shares of common stock related to the potential sale of the Subsequent Notes and Subsequent Warrants to the Investor within 30 calendar days of entry into the Amendment Agreement, and (iv) stipulated that the Investor would release $1,500,000 in cash collateral to the Company, with $1,000,000 to be released to the Company immediately upon singing of the Amendment Agreement and $500,000 to be released upon the Company’s filing of the Schedule 14C. The Company obtained majority stockholder consent to the potential sale of the Subsequent Notes and Subsequent Warrants to the Investor in advance of entry into the Amendment Agreement.
On June 4, 2023, we entered into an amendment to the Amendment Agreement dated May 11, 2023 (the “Amendment to the Amendment Agreement”), for purposes of amending the terms of the SPA. Under the Amendment to the Amendment Agreement, the Company and the Investor agreed as follows: (i) that Section 15(q) to the Convertible Note, which required the Company to hold the Cash Collateral in a Controlled Account Agreement (as defined in the Convertible Note), would no longer be applicable, (ii) that the Investor would stipulate the release to the Company of the remaining Cash Collateral totaling $2,924,000 (thus releasing the full amount of the Cash Collateral to the Company), and (iii) that, should the Investor exercise its option to purchase the Subsequent Notes and Subsequent Warrants, that such Subsequent Notes would omit Section 15(q) and that the Company would not be required to maintain any controlled accounts or otherwise be subject to any controlled account agreements.
On October 14, 2024, the Company commenced the first closing of $600,000 in investments of an up to $1.3 million offering of 5% original issue discount senior secured convertible notes and warrants (the “First Closing”). On October 21, 2024, the Company closed on an additional $231,579 in notes and warrants purchased in the offering (the “Second Closing”), receiving an additional $220,000 in proceeds and bringing the offering to a close after receiving a total of $790,000 in gross proceeds, including $237,500 invested by the Company’s Chief Executive Officer, Dr. Anatoly Dritschilo, in the First Closing. In the Second Closing, two accredited investors purchased a total of $231,579 in notes and 88,544 warrants, exercisable at $1.49 per share, or 125% of the closing price of the Company’s common stock on the day prior to closing.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following Management’s Discussion and Analysis of Financial Condition and Result of Operations (the “MD&A”) should be read in conjunction with our financial statements and the related notes thereto included elsewhere in this Annual Report. The MD&A contains forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations, and intentions. Any statements that are not statements of historical fact are forward-looking statements. When used, the words “believe,” “plan,” “intend,” “anticipate,” “target,” “estimate,” “expect,” and the like, and/or future-tense or conditional constructions (“will,” “may,” “could,” “should,” etc.), or similar expressions, identify certain of these forward-looking statements. These forward-looking statements are subject to risks and uncertainties that could cause actual results or events to differ materially from those expressed or implied by the forward-looking statements in this Annual Report. Our actual results and the timing of events could differ materially from those anticipated in these forward-looking statements as a result of several factors including, but not limited to, those noted under “Risk Factors” in this Annual Report.
We do not undertake any obligation to update forward-looking statements to reflect events or circumstances occurring after the date of this Annual Report, except as required by U.S. federal securities laws.
Overview
Founded by Georgetown University Medical School faculty members, Shuttle Pharmaceuticals Holdings, Inc. is a discovery and development stage pharmaceutical company leveraging our proprietary technology to develop novel therapies that are designed to cure cancer. Originally formed as Shuttle Pharmaceuticals, LLC in 2012, our goal is to extend the benefits of cancer treatments by leveraging insights into cancer therapy with surgery, radiation therapy, chemotherapy and immunotherapy. While there are several therapies being developed with the goal of curing cancer, one of the most effective and proven approaches to this is RT. The Company is developing a pipeline of products designed to address the limitations of the current standard of cancer therapies. We believe that our product candidates will enable us to deliver cancer treatments that are safer, more reliable and at a greater scale than that of the current standard of care.
Operations to date have focused on continuing our research and development efforts to advance Ropidoxuridine clinical testing and improved drug formulation, to advance HDAC6 inhibitor (SP-2-225) preclinical development and explore application of the PC-RAD Test, predictive biomarkers of radiation response. The clinical development of Ropidoxuridine has included completion of a Phase I clinical trial to establish drug bioavailability and a maximum tolerated dose for use in Phase II clinical trials. TCG GreenChem, with whom we have contracted for process research, development and cGMP compliant manufacture of IPdR, has manufactured the API of Ropidoxuridine and the University of Iowa Pharmaceuticals has formulated the drug product for use in the Company’s upcoming Phase II clinical trial in brain cancer patients undergoing radiation therapy. The drug product (capsules) were shipped to CRO Theradex Oncology and distributed to clinical trial sites that are fully approved to enroll patients in the trial. Shuttle received approval from the FDA to begin the clinical trial. The FDA made recommendations to expand the clinical trial to include a randomized dose “optimization” step and we agreed with the recommendation. Meetings with engaged clinical sites to review the protocol documents have occurred and FDA required IRB approvals have been received. With FDA recommended changes incorporated into the revised protocol and the completion of site initiation visits, the Company has commenced its Phase II clinical study. The radiation biomarker project and the health disparities project have been completed and the Company is proceeding with plans for clinical validation and potential for commercialization of Ropidoxuridine as a radiation sensitizer.
Nasdaq Listing Compliance
On December 31, 2024, the Company received a letter from the Nasdaq Listing Qualifications Staff of The Nasdaq Stock Market LLC (“Nasdaq”) stating that for the 30 consecutive business day period between November 15, 2024 to December 30, 2024 the Company’s common stock had failed to maintain a minimum closing bid price of $1.00 per share, as required for continued listing on The Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”). Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company has until June 30, 2025 to regain compliance with the Minimum Bid Price Requirement. To regain compliance, the closing bid price of the Company’s common stock must meet or exceed $1.00 per share for a minimum of 10 consecutive business days.
If the Company cannot regain compliance during the Compliance Period by June 30, 2025, whether organically or by completing a reverse stock split and subsequently trading above $1.00 per share for 10 consecutive trading days, Nasdaq will provide the Company with notice that its common stock will be subject to delisting. At that time, the Company may appeal Nasdaq’s delisting determination to a Nasdaq Hearings Panel.
Nasdaq’s notice to the Company of noncompliance has no immediate effect on the listing of the Company’s common stock and its common stock will continue to be listed on The Nasdaq Capital Market under the symbol “SHPH.” There can be no assurance that the Company will regain compliance with the Minimum Bid Price Requirement or maintain compliance with any of the other Nasdaq continued listing requirements. The Company will continue to monitor the closing bid price of its common stock and will, as appropriate, consider available options to regain compliance with the Minimum Bid Price Requirement.
On September 10, 2024, the Company received a letter from Nasdaq, notifying the Company that it is no longer in compliance with the minimum stockholders’ equity requirement for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires listed companies to maintain stockholders’ equity of at least $2.5 million. In the Company’s Quarterly Report on Form 10-Q for the period ended June 30, 2024, the Company reported stockholders’ equity of $801,434, which is below the minimum stockholders’ equity required for continued listing pursuant to Nasdaq Listing Rule 5550(b)(1). In addition, presently, the Company does not meet the alternatives of market value of listed securities or net income from continuing operations.
On October 15, 2024, the Company submitted a plan to Nasdaq to regain compliance and Nasdaq subsequently granted the Company until March 10, 2025 to regain compliance. We are now in the process of evaluating potential fundraising opportunities, have filed a preliminary registration statement on Form S-1 with the intent of completing an up to $6.5 million public offering, and are working to complete the offering on or prior to March 10, 2025. Nonetheless, there can be no assurance that the Company will be able to regain compliance prior to March 10, 2025, or if the Company fails to satisfy another Nasdaq requirement for continued listing, Nasdaq could provide notice that the Company’s securities will become subject to delisting. In that event, the Company will have an opportunity to appeal Nasdaq’s decision to a hearings panel.

Research and Development. Total research and development (“R&D”) expense was $3.6 million for the year ended December 31, 2024, as compared to $3.5 million for the year ended December 31, 2023. The increase in total R&D expense of $0.1 million, or 3%, is primarily related to the Company having completed production of the drug product and the start of work related to the initiation of trials including contract research organization (“CRO”) expenses, clinical trial sites, other regulatory activities.
R&D compensation related expenses were $1.3 million in the year ended December 31, 2024 as compared to $1.5 million in the year ended December 31, 2023. For the year ended December 31, 2024, R&D compensation related expenses was 35% as a percent of total R&D expense, representing a decrease from the 43% of total R&D incurred in the year ended December 31, 2023. Subcontractor expense made up 60% of total R&D expenses in the year ended December 31, 2024 and 52% of total R&D expenses during the year ended December 31, 2023.
General and Administrative Expenses. General and Administrative expenses in the year ended December 31, 2024 increased by $0.3 million, or 33%, from $1.0 million in the year ended December 31, 2023 to $1.4 million in the year ended December 31, 2024. The increase in general and administrative expenses was primarily due to costs associated with advertising of $0.1 million and marketing of $0.1 for investor relations and other administrative costs.
Legal and Professional Expenses. During the year ended December 31, 2024, legal and professional expenses increased by $1.4 million or 102%. The increase in legal and professional fees was primarily due to increases in our accounting expenses related to our public filing requirements, legal and professional fees related to our restatement of certain prior periods and contracts.
Other Income (expense). During the year ended December 31, 2024, other expense increased by $0.7 million or 107%. The increase was primarily driven by a $1.7 million change in fair value of derivative liabilities and a $0.4 million loss on settlement of convertible debt related to the settlement of the Alto Convertible Note. These increases were partially offset by a decrease in interest expense of $1.3 million which was also due to the settlement of the Alto Convertible Note during the period ended September 30, 2024.
Liquidity and Capital Resources
Our consolidated financial statements are prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. We have incurred losses since inception and had a net loss of $9.1 million and no revenues during the year ended December 31, 2024 and working capital of approximately $0.7 million as of December 31, 2024. We do not expect to generate positive cash flows from operating activities in the near future.
In October 2024, we completed an equity raise that provided $3.7 million net cash, after deducting placement agent fees of $0.5 million and issuance costs of $0.3 million, for the issuance of 395,574 shares of common stock and 2,555,246 pre-funded warrants, accompanied by an aggregate of 2,950,820 warrants with an exercise price of $1.40 per share. Also in October 2024, we completed an offering of senior secured convertible bridge notes, receiving $0.7 million in cash, after deducting issuance costs. The notes have a term of one-year and were accompanied by 329,461 warrants with a weighted-average exercise price of $1.42 per share. Refer to the “Recent Financing” section below for additional information. In September 2024, our CEO provided $0.3 million to us in exchange for a promissory note repayable in equal monthly installments of principal and interest over a term of one year. However, our existing cash resources and the cash received from the equity offering and senior convertible note are not expected to provide sufficient funds to carry out our operations and clinical trials through the next twelve months.
Our capital raises have to date supported operations, the manufacture of drug product and FDA approval of the IND for the Phase II clinical trial of Ropidoxuridine and radiation therapy in glioblastoma and other radiation sensitizer discovery and therapy. The FDA recommended and we have agreed to an expansion of the Phase II clinical trial, necessitating additional capital to complete the trial as well as fund ongoing operations. Additionally, the Phase II clinical trial of Ropidoxuridine has evolved with finalized agreements with all six of the planned site enrollment locations to administer the Phase II clinical trial of Ropidoxuridine and the enrollment of the first three patients.
The ability of the Company to continue as a going concern is dependent upon its ability to continue to successfully raise additional equity or debt financing to allow it to fund ongoing operations, conduct clinical trials and bring a drug candidate to commercialization to generate revenues. These conditions raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued.

As of December 31, 2023, total current assets were $5.6 million and total current liabilities were $1.0 million, resulting in a working capital of $4.6 million. The Company’s current assets as of December 31, 2024 are comprised of $1.9 million of cash and cash equivalents and $0.3 million of prepaid expenses, with the decrease from December 31, 2023 being primarily due to ongoing cash burn from our R&D programs, filing expenses, reaudits, and general operations.
In addition, we continued progress on our R&D programs during the year ended December 31, 2024 that resulted in increased cash expenditures. The Company’s current liabilities as of December 31, 2024 are primarily comprised of $0.7 million of convertible notes payable, $0.6 million of accounts payable and accrued expenses, $0.2 million of notes payable to related parties, and the current portion of our operating lease liability of $0.1 million. The increase in current liabilities is primarily due to an increase in accounts payable and accrued expenses of $0.2 million, notes payable to related parties of $0.2 million, and convertible note payable of $0.1 million, primarily attributable to our efforts to preserve cash while we strive to raise funds to finance ongoing business and operations.

Cash Flows from Operating Activities
Our cash flows from operating activities are greatly influenced by our use of cash for operating expenses and working capital requirements to support the business. We have historically experienced negative cash flows from operating activities as we invested in research and development activities. The cash used in operating activities resulted primarily from our net losses adjusted for non-cash charges, which are generally attributable to stock-based compensation, changes in fair value of our derivative liabilities and amortization of debt discounts and finance fees, as well as changes in components of operating assets and liabilities, which are generally attributable to increased expenses and timing of vendor payments.
During the year ended December 31, 2024, net cash used in operating activities of $7.3 million was primarily due to our net loss of $9.1 million and a change in derivative liability of $0.6 million, partially offset by $1.1 million of amortization of debt discount and finance fees and $0.8 million of loss on settlement of convertible notes payable.
During the year ended December 31, 2023, net cash used in operating activities of $5.6 million was primarily due to our net loss of $6.6 million, partially offset by $0.5 million of loss on settlement of convertible notes payable and $0.3 million of accrued interest settled with common stock.
Cash Flows from Investing Activities
For the year ended December 31, 2024, cash flows provided by investing activities was primarily attributable to $3.0 million in proceeds from disposition of marketable securities, used to fund the Company’s ongoing operations. For the year ended December 31, 2023, cash flows used in investing activities was primarily attributable to the Company’s net investments in marketable securities of $2.8 million.
Cash Flows from Financing Activities
For the year ended December 31, 2024, cash flows from financing activities was primarily comprised of net proceeds from the sale of common stock, warrants and pre-funded warrants of $4.0 million, partially offset by $0.3 million of issuance costs, and proceeds from the issuance of convertible notes of $0.8 million, partially offset by issuance costs of $0.1 million, used to finance the Company’s ongoing operations. For the year ended December 31, 2023, the Company received net proceeds of $3.9 million from the sale and issuance of convertible notes payable and warrants and repaid $0.3 million in convertible notes, $0.3 million for finance costs related to convertible note payable, and $0.7 million in related party notes payable, all of which was used to finance the Company’s ongoing operations.
Recent Financings
On January 11, 2023, the Company entered into a stock purchase agreement (the “SPA”) with the Alto Opportunity Master Fund, SPC - Segregated Master Portfolio B, a Cayman entity (the “Investor”), pursuant to which the Company sold to the Investor a $4.3 million convertible note (the “Convertible Note”) and warrant (the “Warrant”) to purchase 127,260 shares of common stock of the Company, in exchange for gross proceeds of $4.0 million Investment Amount. The Convertible Note amortizes on a monthly basis and the Company can make such monthly amortization payments in cash or, subject to certain equity conditions, in registered shares of common stock or a combination thereof. For equity repayment, the Convertible Note is convertible into shares of common stock at price per share equal to the lower of (i) $18.80 (ii) 90% of the three lowest daily volume-weighted average price (“VWAP”) of the 15 trading days prior to the payment date or (iii) 90% of the VWAP of the trading day prior to payment date. The Convertible Note is repayable over 26 months and bears interest at the rate of 5% per annum. The Warrant is exercisable for four years from the date of closing and is exercisable at $0.48 per share, as adjusted. In the event the Investor exercises the Warrant in full, such exercise would result in additional gross proceeds to the Company of approximately $0.1 million.
On May 10, 2023, the Company entered into an amendment agreement to the SPA (the “Amendment Agreement”). Under the Amendment Agreement, the Company and the Investor amended the transaction documents as follows: (i) amended and restated Section 2 of the Warrant so as to remove a provision that would have potentially required an adjustment to the number of warrant shares exercisable under the Warrant, (ii) stipulated that the Company would obtain majority shareholder approval to issue up to an additional $10 million Subsequent Notes and Subsequent Warrants equal to 42.5% of the outstanding principal value of the Subsequent Notes, which Subsequent Note and Subsequent Warrant would be sold to the Investor on substantially the same terms as the existing Convertible Note and Warrant (each as amended by the Amendment Agreement) and upon conversion and/or exercise would cause the potential issuance of in excess of 19.9% of the Company’s issued and outstanding stock, (iii) that, upon obtaining majority stockholder approval, the Company would file a Schedule 14C related to such potential issuance of the shares of common stock related to the potential sale of the Subsequent Notes and Subsequent Warrants to the Investor within 30 calendar days of entry into the Amendment Agreement, and (iv) stipulated that the Investor would release $1,500,000 in cash collateral to the Company, with $1,000,000 to be released to the Company immediately upon singing of the Amendment Agreement and $500,000 to be released upon the Company’s filing of the Schedule 14C. The Company obtained majority stockholder consent to the potential sale of the Subsequent Notes and Subsequent Warrants to the Investor in advance of entry into the Amendment Agreement.
On June 4, 2023, the Company entered into an amendment to the Amendment Agreement dated May 11, 2023 (the “Amendment to the Amendment Agreement”), for purposes of amending the terms of the SPA. Under the Amendment to the Amendment Agreement, the Company and the Investor agreed as follows: (i) that Section 15(q) to the Convertible Note, which required the Company to hold the Cash Collateral in a Controlled Account Agreement (as defined in the Convertible Note), would no longer be applicable, (ii) that the Investor would stipulate the release to the Company of the remaining Cash Collateral totaling $2,924,000 (thus releasing the full amount of the Cash Collateral to the Company), and (iii) that, should the Investor exercise its option to purchase the Subsequent Notes and Subsequent Warrants, that such Subsequent Notes would omit Section 15(q) and that the Company would not be required to maintain any controlled accounts or otherwise be subject to any controlled account agreements. The Convertible Note was paid in full as of September 30, 2024.
During October 2024, the Company completed a senior convertible note offering in two closings, as further described below.
On October 14, 2024, the Company closed on $600,000 of an up to $1.3 million 5% original issue discount senior secured convertible note and warrant offering (the “Offering”), entering into securities purchase agreements with a small group of accredited investors. The Company’s Chief Executive Officer, Anatoly Dritschilo, invested $237,500 in the Offering.
On October 21, 2024, the Company closed on an additional $231,579 in Notes and Warrants purchased in the Offering (the “Second Closing”), receiving an additional $220,000 in proceeds and bringing the Offering to a close after receiving a total of $790,000 in gross proceeds, including $237,500 invested by the Company’s Chief Executive Officer in the First Closing. In the Second Closing, two accredited investors purchased a total of $231,579 in Notes and 88,544 Warrants, exercisable at $1.49 per share, or 125% of the closing price of the Company’s common stock on the day prior to closing. The Company received total net proceeds of $682,510 from the Offering. To date, the warrants from the Offering have yet to be exercised.
On October 31, 2024, the Company consummated a public offering of an aggregate of (i) 395,574 Shares of common stock, and 2,555,246 Pre-Funded Warrants to purchase up to 2,555,246 shares of common stock, and (ii) 2,950,820 Common Warrants to purchase up to 2,950,820 Common Warrant Shares. Each share of common stock, or Pre-Funded Warrant in lieu thereof, was sold together with an accompanying Common Warrant to purchase one share of common stock. The public offering price for each share of common stock and one accompanying Common Warrant was $1.525. The public offering price of each Pre-Funded Warrant and one accompanying Common Warrant was $1.524, which equals the price at which one share of common stock and accompanying Common Warrant was sold to the public in the offering, minus $0.001. The exercise price of each Pre-Funded Warrant is $0.001 per share. Each Common Warrant offered in the offering is exercisable for one share of common stock and has an initial exercise price equal to $1.40. The Company received aggregate gross proceeds from the offering of approximately $4.5 million, before deducting placement agents’ fees and other offering expenses. A.G.P./Alliance Global Partners and Boustead served as placement agents of this offering. The Company received proceeds from the offering of approximately $4.0 million, net of placement agent fees of $0.5 million.
Off-Balance Sheet Arrangements
The Company does not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.
Critical Accounting Policies and Significant Judgments and Estimates
This discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that the Company believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. While the significant accounting policies are described in more detail in the notes to the consolidated financial statements included elsewhere in this report, the Company believes that the following accounting policies are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates.
Our most critical accounting policies and estimates relate to the following:
● Research and Development Expenses
● Fair Value of Convertible Notes
● Fair Value of Warrant to Purchase Common Stock
● Fair Value of Derivative Financial Instruments
Research and Development Expenses
Research and development expenses are expensed as incurred, net of contract expense reimbursements, if applicable. Research and development expenses include, but are not limited to, product development, clinical and regulatory expenses, payroll and other personnel expenses, and are subject to allocation.
Fair Value of Convertible Notes
As permitted under ASC 825, Financial Instruments (“ASC 825”), the Company elected the fair value option to account for the October 2024 Convertible Bridge Notes. The valuation of the October 2024 Convertible Bridge Notes utilizes a Monte Carlo simulation model. Monte Carlo simulation models require the use of simulations that are weighted based on projected future stock prices, the volatility of a set of guideline companies and significant unobservable inputs including probabilities assigned to not achieving a successful capital raise and a registration of related securities. Each simulation is based on the range of inputs in a scenario with the mean of the output on each simulation calculated as an average.
The significant inputs and assumptions used to estimate the fair value also include: (i) the expected timing of conversion, (ii) the amount subject to equity conversion, (iii) the sum of the notes’ principal and unpaid accrued interest, (iv) expected volatility, (v) risk-free interest rate, (vi) the discount rate, (vii) volume-weighted average price (“VWAP”), (viii) illiquidity discounts, and (ix) probabilities assigned. The October 2024 Convertible Bridge Notes are subject to revaluation at the end of each reporting period, with changes in fair value recognized in the accompanying Consolidated Statement of Operations, or for changes due to the Company’s credit worthiness, if any, as a component of other comprehensive income.
Fair Value of Warrants to Purchase Common Stock
The Company has issued warrants to investors in our debt and equity offerings. The Company has also issued warrants to service providers in relation to our financing offerings.
We evaluate all warrants issued to determine the appropriate classification under ASC 480 and ASC 815 (as well as under ASC 718 for warrants issued as share-based payments). In addition to determining classification, we evaluate these instruments to determine if such instruments meet the definition of a derivative.
For warrants that are determined to be equity-classified, we estimate the fair value at issuance and record the amounts to additional paid in capital (potentially on a relative fair value basis if issued in a basket transaction with other financial instruments). Warrants that are equity-classified are not subsequently remeasured unless modified or required to be reclassified as liabilities. For warrants that are determined to be liability-classified, we estimate the fair value at issuance and each subsequent reporting date, with changes in the fair value reported in the consolidated statements of operations. The classification of all outstanding warrants, including whether such instruments should be recorded as equity, is evaluated at the end of each reporting period.
For warrants with uncertain or more complex terms (such as variability in the warrant shares or exercise price), we may utilize more complex models to address such provisions, including Monte Carlo simulation models. Monte Carlo simulation models require the use of simulations that are weighted based on projected future stock prices, the volatility of a set of guideline companie s and significant unobservable inputs including probabilities assigned. Each simulation is based on the range of inputs in a scenario with the mean of the output on each simulation calculated as an average.
The use of these valuation models requires the input of highly subjective assumptions. Any change to these inputs could produce significantly higher or lower fair value measurements.
Fair Value of Financial Instruments
We evaluate our financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, such as the Acceleration Option in the Alto Convertible Note (as defined in Note 5). For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the consolidated statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities are evaluated at the end of each reporting period.
For our derivative financial instruments classified as a liability, the Company uses a Monte Carlo valuation model to value the derivative instruments at inception and on subsequent valuation dates. The model requires the use of simulations that are weighted based the volatility of a set of guideline companies and significant unobservable inputs including probabilities assigned. Each simulation is based on the range of inputs in a scenario with the mean of the output on each simulation calculated as an average. The Monte Carlo simulation uses an implied VWAP for valuation. The implied VWAP was backsolved by setting the summation of the parts (e.g., derivatives and debt without derivatives) equal to the cash proceeds and is updated each period.
The use of Monte Carlo valuation models require key inputs, some of which are based on estimates and judgements by management. Any change to these key inputs could produce significantly higher or lower fair value measurements.

Consolidated Statements of Operations for the years ended December 31, 2024 and 2023
Consolidated Statements of Changes in Stockholders’ Equity for the years ended December 31, 2024 and 2023

Notes to Consolidated Financial Statements
Report of Independent Registered Public Accounting Firm
To the Shareholders, Board of Directors, and Audit Committee of Shuttle Pharmaceuticals Holdings, Inc.
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Shuttle Pharmaceuticals Holdings, Inc. and subsidiaries (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations, changes in stockholders’ equity, and cash flows for each of the years in the two-year period ended December 31, 2024, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
Going Concern
The accompanying financial statements have been prepared assuming the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has suffered recurring losses and negative cash flows from operations since inception. These conditions as set forth in Note 1, raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits.
We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Note 1 - Organization and Liquidity
Organization and Line of Business
Shuttle Pharmaceuticals Holdings, Inc. (“we,” “us,” “our,” or the “Company”) was originally formed as Shuttle Pharmaceuticals, LLC in the State of Maryland on December 18, 2012. On August 12, 2016, the Company filed articles of conversion with the State of Maryland to convert from an LLC to a C corporation, at which time the Company changed its name to Shuttle Pharmaceuticals, Inc. (“Shuttle”). In connection with the conversion the Company issued 5,625,000 shares of common stock in exchange for 100% of the outstanding membership interests in Shuttle prior to conversion. On June 4, 2018, Shuttle completed a reverse merger with Shuttle Pharmaceuticals Holdings, Inc. (then known as Shuttle Pharma Acquisition Corp, Inc.), a Delaware corporation, pursuant to which Shuttle, our operating entity, became a wholly-owned subsidiary of the Company. Our wholly-owned subsidiary Shuttle Diagnostics, Inc. was formed in the State of Maryland on November 15, 2023. All share numbers referenced herein reflect a 1-for-8 reverse split of our common stock on a post-split basis, which was effective as of August 13, 2024 (see Note 2).
The Company’s primary purpose is to develop and commercialize unique drugs for the sensitization of cancers and protection of normal tissues, with the goal of improving outcomes for cancer patients receiving radiation therapy. Shuttle has deployed its proprietary technology to develop novel cancer immunotherapies, producing a pipeline of selective HDAC inhibitors for cancer and immunotherapy applications. The Company’s HDAC platform is designed to target candidate molecules with potential roles in therapeutics beyond cancer, including autoimmune, inflammatory, metabolic, neurological and infectious diseases. The Company’s Ropidoxuridine product, which is used with radiation therapy to sensitize cancer cells, was initially funded by a Small Business Innovation Research (“SBIR”) contract provided by the National Cancer Institute (“NCI”), a unit of the National Institutes of Health (“NIH”). Ropidoxuridine has been further developed through the Company’s collaborations with scientists at the University of Virginia for use in combination with proton therapy to improve patient survival. Historically, and prior to the Company’s initial public offering in September 2022, the Company had obtained funding to develop products through NIH grants, including a product to predict late effects of radiation with metabolite biomarkers and develop prostate cancer cell lines in health disparities research.
The production and marketing of the Company’s products and its ongoing research and development activities will be and are subject to extensive regulation by numerous governmental authorities in the United States. Prior to marketing in the United States, any products or combination of products developed by the Company must undergo rigorous preclinical (animal) and clinical (human) testing and an extensive regulatory approval process implemented by the Food and Drug Administration (“FDA”) under the Food, Drug and Cosmetic Act. There can be no assurance that the Company will not encounter problems in its clinical trials that will cause the Company or the FDA to delay or suspend the clinical trials.
The Company’s success will depend in part on its ability to obtain patents and product license rights, maintain trade secrets, and operate without infringing on the proprietary rights of others, both in the United States and in other countries. There can be no assurance that patents issued to or licensed by the Company will not be challenged, invalidated or circumvented, or that the rights granted thereunder will provide proprietary protection or competitive advantages to the Company now or in the future.
Liquidity and Going Concern
Our consolidated financial statements are prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has incurred losses since inception and has a net loss of approximately $9.1 million and no revenues for the year ended December 31, 2024 and working capital of approximately $0.7 million as of December 31, 2024. The Company does not expect to generate positive cash flows from operating activities in the near future.
In September 2024, the Company’s CEO provided $250 thousand to the Company in exchange for a promissory note repayable in equal monthly installments of principal and interest over a term of one year. In October 2024, the Company completed an offering of senior secured convertible bridge notes, receiving $790 thousand in cash. The notes have a term of one-year and were accompanied by 329,461 warrants with a weighted-average exercise price of $1.42. Also in October 2024, the Company completed an equity raise that provided $4.0 million in cash, net of placement agent fees of $0.5 million, for the issuance of 2.9 million shares / pre-funded warrants, and 2.9 million warrants with an exercise price of $1.40. However, the Company’s existing cash resources and the cash received from the equity offering and senior convertible note are not expected to provide sufficient funds to carry out the Company’s operations and clinical trials through the next twelve months.
The ability of the Company to continue as a going concern is dependent upon its ability to continue to successfully raise additional equity or debt financing to allow it to fund ongoing operations, conduct clinical trials and bring a drug candidate to commercialization to generate revenues. These conditions raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued.
The accompanying consolidated financial statements do not include any adjustments to reflect the future effects on the recoverability and classification of assets or the amounts and classification of liabilities if the Company is unable to continue as a going concern.
Note 2 - Summary of Significant Accounting Policies
Basis of Presentation
These consolidated financial statements and related disclosures have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The consolidated financial statements and disclosures have been prepared using the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”).
Reverse Stock Split
On August 13, 2024, in order to meet Nasdaq’s minimum bid price requirement of $1.00 per share (the “Minimum Bid Price Requirement”), the Company effectuated a 1-for-8 reverse stock split of its issued and outstanding common stock, rounding up to account for any fractional shares (the “Reverse Stock Split”). The Reverse Stock Split had no effect on the Company’s authorized shares of common stock or preferred stock and the par value will remain unchanged at $0.00001, respectively. All common stock share, option, warrant and per share amounts (except our authorized but unissued shares and previously reserved shares) have been retroactively adjusted in these consolidated financial statements and related disclosures.
Basis of Consolidation
The consolidated financial statements have been prepared on a consolidated basis with those of the Company’s wholly-owned subsidiaries, Shuttle Pharmaceuticals, Inc. and Shuttle Diagnostics, Inc. All intercompany transactions and balances have been eliminated.
Use of Estimates
The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company regularly evaluates estimates and assumptions. The Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from the Company’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected. Significant estimates are contained in the accompanying consolidated financial statements for the valuation of debt and warrants and valuation of bifurcated derivative liabilities and other financial instruments.
Cash and Cash Equivalents
Cash and cash equivalents include cash in bank accounts and money market funds with maturities of less than three months from inception, which are readily convertible to known amounts of cash and which, in the opinion of management, are subject to an insignificant risk of loss in value. As of December 31, 2024 and 2023, cash and cash equivalents consisted of the following:
Schedule of Cash and Cash Equivalents
December 31,
Cash $ 1,918,941 $ 1,550,098
Money market funds 1,203 1,026,318
Total cash and cash equivalents $ 1,920,144 $ 2,576,416
Periodically, the Company may carry cash balances at financial institutions in excess of the federally insured limit of $250,000 per institution. The amount in excess of the FDIC insurance as of December 31, 2024 was approximately $1.7 million. The Company has not experienced losses on these accounts and management believes, based upon the quality of the financial institutions, that the credit risk with regard to these deposits is not significant.
Marketable Securities
Our investments in debt securities are carried at fair value. Investments in debt securities that are not classified as held-to-maturity are carried at fair value and classified as either trading or available-for-sale. Realized and unrealized gains and losses on trading of debt securities are charged to income.
The marketable securities held by the Company, which are classified as trading marketable securities, consisted of an outstanding balance of $0 and $2.9 million as of December 31, 2024 and 2023, respectively. As of the years ended December 31, 2024 and 2023, the Company recognized interest income of less than $0.1 million and $0.1 million, realized gains of less than $0.1 million and less than $0.1 million, and unrealized gain of $0 and $0.1 million, respectively.
Fair Value of Financial Instruments
The Company follows accounting guidelines on fair value measurements for financial instruments measured on a recurring basis, as well as for certain assets and liabilities that are initially recorded at their estimated fair values. Fair value is defined as the exit price, or the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The Company uses the following three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs to value its financial instruments:
● Level 1: Observable inputs such as unadjusted quoted prices in active markets for identical instruments.
● Level 2: Quoted prices for similar instruments that are directly or indirectly observable in the marketplace.
● Level 3: Significant unobservable inputs which are supported by little or no market activity and that are financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires a significant judgment or estimation.
Financial instruments measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires the Company to make judgments and consider factors specific to the asset or liability. The use of different assumptions and/or estimation methodologies may have a material effect on estimated fair values. Accordingly, the fair value estimates disclosed, or initial amounts recorded, may not be indicative of the amount that the Company or holders of the instruments could realize in a current market exchange.
The carrying amounts of the Company’s financial instruments including cash and cash equivalents, prepaid expenses, accounts payable and accrued liabilities approximate fair value due to the short-term maturities of these instruments.
Set out below are the Company’s financial instruments that are required to be remeasured at fair value on a recurring basis and their fair value hierarchy as of December 31, 2024 and 2023:

See Note 5 and Note 7 for additional disclosures related to the fair value of the Company’s convertible notes and derivative liabilities, respectively.
Leases
The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use asset (“ROU”), operating lease liability - current, and operating lease liability - noncurrent on the consolidated balance sheets.
ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the related obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the estimated rate of interest for collateralized borrowing, over a similar term of the lease payments at commencement date. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
Leases with a lease term of 12 months or less at inception are not recorded on the consolidated balance sheets and are expensed on a straight-line basis over the lease term in the consolidated statement of operations. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately.
The Company determines the present value of minimum future lease payments for operating leases by estimating a rate of interest that it would have to pay to borrow on a collateralized basis over a similar term, an amount equal to the lease payments and a similar economic environment (the “incremental borrowing rate” or “IBR”). The Company determines the appropriate IBR by identifying a reference rate and making adjustments that take into consideration financing options and certain lease-specific circumstances. For the reference rate, the Company used an equity built up, risk adjusted rate, as the implicit interest rate.
Property and Equipment
Property and equipment are stated at cost less accumulated depreciation. Expenditures for maintenance and repairs are charged to expense as incurred; additions, renewals and betterments are capitalized. When property and equipment are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts, and any gain or loss is included in operations. Depreciation of property and equipment is provided using the straight-line method for substantially all assets with estimated lives as follows:
Schedule of Useful Lives for Property Plant Equipment
Furniture 5 years
Computers and equipment 5 years
Research Equipment 10 years
Derivative Financial Instruments
The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risks. The Company evaluates all of its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value and is then re-valued at each reporting date, with changes in the fair value reported in the consolidated statements of operations.
For its derivative financial instruments, the Company utilizes the most appropriate valuation model (such as Monte Carlo simulations or other sophisticated models, based on the nature of the terms of the instrument) to value the derivative instruments at inception and on subsequent valuation dates. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the consolidated balance sheet sheets as current or non-current based on whether or not net-cash settlement or conversion of the instrument could be required within twelve (12) months of the balance sheet date.
Convertible Notes
The Company accounts for its Convertible Bridge Notes (as defined in Note 5) under the fair value option in accordance with ASC 825. The fair value option may be elected on an instrument-by-instrument basis and is irrevocable unless a new election date occurs. Additional term or other notes may be issued in subsequent periods where the Company would be able to make a fair value option election upon issuance provided eligibility criteria are met. The Company records the portion of the Convertible Bridge Notes that are issued and outstanding for accounting purposes at fair value with changes in fair value recorded in other income (expense), net in the consolidated statements of operations, except for the portion of the total change in fair value that results from a change in the instrument-specific credit risk of the Convertible Bridge Notes, which is recorded in other comprehensive income (loss), if applicable. No loss was attributed to changes in credit risk for the periods presented therefore net loss was equal to comprehensive loss. The fair value option election was made at the initial transaction date to align the accounting for the Convertible Bridge Notes with the Company’s financial reporting objectives and reduce operational effort to account for embedded features that otherwise would require bifurcation as a separate unit of account.
Pursuant to the fair value option election, direct and incremental debt issuance costs and consideration paid to the lender related to the Convertible Bridge Notes were expensed as incurred and recorded in other income (expense), net in the consolidated statements of operations.
For convertible notes for which the fair value option is not elected, the Company evaluates the convertible notes for embedded features and bifurcates these features (such as conversion options and redemption options) from their host instruments and accounts for them as freestanding derivative financial instruments if certain criteria are met. The criteria include circumstances in which (a) the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract, (b) the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value under otherwise applicable generally accepted accounting principles with changes in fair value reported in earnings as they occur and (c) a separate instrument with the same terms as the embedded derivative instrument would be considered a derivative instrument. The Company’s convertible notes where fair value option was not elected were liquidated by December 31, 2024.
Warrants
The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in FASB ASC 480, Distinguishing Liabilities from Equity (“ASC 480”) and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. Finally, the Company determines if the warrants meet the definition of a derivative based on their contractual terms. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.
For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and at each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the consolidated statements of operations. The Company also evaluates if changes in contractual terms or other considerations would result in the reclassification of outstanding warrants from liabilities to stockholders’ equity (or vice versa).
The fair value of the warrants is estimated using a Monte Carlo simulation. Warrants that have terms greater than one year are classified as non-current liabilities in the balance sheet, unless there is an indication that the warrants would be settled within one year.
Impairment of Long-Lived Assets
The Company reviews its long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the asset may not be fully recoverable. Recoverability of assets is measured by a comparison of the carrying amount of an asset to the estimated undiscounted cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated future cash flows, an impairment charge will be recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. There were no impairments of long-lived assets during the periods presented.
Stock-Based Compensation
Compensation cost for stock awards, which include restricted stock units (“RSUs”), is measured at the fair value on the grant date and recognized as expense, over the related service period. The fair value of stock awards is based on the quoted price of our common stock on the grant date. Compensation expense related to the RSUs is reduced by the fair value of the units that are forfeited by employees that leave the Company prior to vesting as they occur. Compensation cost for RSUs is recognized using the straight-line method over the requisite service period.
Research and Development Expenses
Research and development expenses are charged to expense as incurred. Research and development expenses include, but are not limited to, product development, clinical and regulatory expenses, payroll and other personnel expenses, which include a certain portion of the Company’s chief executive officer, chief operating officer, vice president regulatory (formerly the chief financial officer) and directors’ compensation. For the year ended December 31, 2024 and 2023, a portion of personnel-related expenses and stock-based compensation expense for these individuals totaling $0.5 million and $0.8 million, respectively, was included within research and development due to their active involvement in the research and development activities, materials, supplies, related subcontract expenses, and consulting costs.
Regarding the accounting treatment for reimbursements, GAAP provides limited guidance on the accounting for government grants received by for-profit companies. In accordance with ASC Topic 832, Government Assistance, as adopted January 1, 2022, the Company discloses certain types of government assistance received in the notes to the consolidated financial statements that includes: a) the nature of the transaction including the nature of the assistance being given, b) the accounting policies being used to account for the transaction and c) other provisions of relevance, where required. Depending on the type of grant or contract, the Company understands there is more than one acceptable alternative for the accounting treatment - a reduction of costs, a deferred credit to be amortized, revenue or other income. The Company has concluded that reimbursements received for R&D expenses incurred are more akin to a reduction of costs and applies reimbursements against incurred research costs. For the years ended December 31, 2024 and 2023, the Company recorded $3.6 million and $3.5 million, respectively, in research and development.
Income Taxes
The Company accounts for income taxes in accordance with ASC Topic 740, Income Taxes. ASC 740 requires a company to use the asset and liability method of accounting for income taxes, whereby deferred tax assets are recognized for deductible temporary differences, and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, the Company does not foresee generating taxable income in the near future and utilizing its deferred tax asset, therefore, it is more likely than not that some portion, or all of, the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.
Under ASC 740, a tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company has no material uncertain tax positions for any of the reporting periods presented.
Segment Information
Operating segments are defined as components of an enterprise about which separate and discrete information is available for evaluation by the chief operating decision-maker (“CODM”) in deciding how to allocate resources and assess performance. The Company’s CODM and the Company’s chief executive officer evaluates the Company’s operations and manages its business as a single operating segment. All of the Company’s long-lived assets are held in the United States. Refer to Note 9 for the Company’s disclosure on its single operating segment.
Net Loss Per Common Stock
Net loss per share of common stock requires presentation of basic and diluted earnings per common share on the face of the statements of operations for all entities with complex capital structures and requires a reconciliation of the numerator and denominator of the basic earnings per share computation to diluted earnings per share.
In the accompanying consolidated financial statements, basic loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during the year. Certain warrants issued and outstanding include terms and conditions resulting in the treatment as participating securities. Such warrants do not include an obligation for the warrant holders to fund the losses of the Company. Therefore, these warrants are excluded from the calculation of earnings per common share in periods of net loss.
Diluted earnings per share is computed by dividing net income attributable to common stockholders by the weighted average number of shares of common stock outstanding and potentially dilutive shares of common stock during the period to reflect the potential dilution that could occur from common shares issuable through convertible securities, contingent share arrangements, stock options and warrants unless the result would be antidilutive.
The dilutive effect of restricted stock units and other stock-based payment awards subject to vesting and common stock warrants is calculated using the “treasury stock method,” which assumes that the “proceeds” from the exercise of these instruments are used to purchase common shares at the average market price for the period. The dilutive effect of convertible securities is calculated using the “if-converted method.” Under the if-converted method, securities are assumed to be converted at the beginning of the period, and the resulting shares of common stock are included in the denominator of the diluted calculation for the entire period being presented.
Given the nominal exercise price of the Company’s issuance of Pre-Funded Warrants (as defined in Note 6), such Pre-Funded Warrants are included in in the calculation of basic and diluted net loss per share as the exercise price per warrant is deemed nonsubstantive when compared to the fair value of the underlying common shares. The 1,826,000 unexercised pre-funded warrants as of December 31, 2024 were included in the Company’s calculation of basic and diluted loss per share.
For the years ended December 31, 2024 and 2023, the following common stock equivalents were excluded from the computation of diluted net loss per share as the result of the computation was anti-dilutive.

Recently Adopted Accounting Pronouncements
In November 2023, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (“ASU”) 2023-07, with the goal of enhancing segment disclosures under Topic 280 - Segment Reporting. This Update is applicable for all public entities. The amendments in this Update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted the provisions of ASU 2023-07 as of January 1, 2024, for the fiscal years ended December 31, 2024 and 2023 using the retrospective approach (Note 9).
Recently Issued Accounting Pronouncements
In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The guidance is effective for the Company’s fiscal years beginning after December 15, 2024, with early adoption permitted. The Company does not expect the adoption of this standard to have any material impact on its financial statements.
On November 4, 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses (“DISE”),” which requires disaggregated disclosure of income statement expenses for public business entities. The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the notes to the financial statements. ASU 2024-03 is effective for all public business entities for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the potential impact that this standard may have on its consolidated financial statements and related disclosures.
There have been no other recent accounting pronouncements, changes in accounting pronouncements or recently adopted accounting guidance during the year ended December 31, 2024 that are of significance or potential significance to the Company.
Note 3 - Leases
Operating lease right-of-use (“ROU”) assets and liabilities are recognized at the present value of the future lease payments as of the lease commencement date. Operating lease expense is recognized on a straight-line basis over the lease term.
The Company currently has a lease agreement which allows for the use of a laboratory facility, entered into on February 16, 2023, with base rent of $7,206 per month for a period of 64 months, which increases at the rate of 3% per year, that commenced June 1, 2023. The lease included a six-month 50% rent abatement upon commencement. Additional common area maintenance (“CAM”) fees are charged monthly and revised annually. The estimated monthly CAM fees are $3,300 per month for the first year of the lease, which are being expensed as incurred. An irrevocable letter of credit (“LOC”) for the security deposit of $43,234 and base rent of $3,891, including 50% abatement, and $3,315 of CAM cost, was due and paid on execution of the lease agreement. Alexandria Real Estate (ARE-QRS-CORP) is the beneficiary of the LOC, and the expiry date of the LOC is March 1, 2025.

On October 14, 2024, as part of the senior convertible note offering described in Note 5, the Company entered into a loan with an officer of the Company in the amount of $250,000 (principal) with an interest rate of 14.5% per annum due October 13, 2025, and warrants to purchase 100,382 shares of common stock at an exercise price of $1.40 per share. As of December 31, 2024, there was outstanding principal and interest balances for these related party notes of $250,000 and $7,955, respectively. Under the fair value option, the senior convertible note is $206,085 as of December 31, 2024.
On September 4, 2024, the Company issued a $250,000 promissory note (the “Promissory Note”) to an officer of the Company for $250,000. The Promissory Note accrues interest at 12% per annum and is repayable in 12 substantially equal installments over a period of one year. During the year ended December 31, 2024 the Company incurred $8,692 in interest expense relating to this Promissory Note. During the year ended December 31, 2024 the Company repaid principal and interest of $59,730 and $6,907, respectively.
Prior to December 31, 2022, the Company entered into a series of loans, which were subsequently consolidated and amended, with an officer of the Company and his spouse, resulting in the following two loans: (i) a single loan from the spouse of an officer of the Company, dated December 1, 2020, with a principal balance of $0.4 million, bearing interest at the rate of 7.5% per annum; and (ii) a single loan owed to an officer of the Company in the principal amount of $0.1 million, bearing interest at the rate of 7.5% per annum. The notes matured on June 30, 2023 and were paid in full. During the year ended December 31, 2023, principal payments of $0.6 million and interest of $0.1 million were paid.
Note 5 - Convertible Notes
Convertible Bridge Notes
During October 2024, the Company completed a senior convertible note offering in two closings, as further described below.
On October 14, 2024, the Company issued an aggregate of $600,000 (of an up to $1.3 million authorized financing) senior secured convertible notes due in October 2025, which accrue interest at 14.5% interest per year. The notes include a 5% original issue discount and the Company received $570,000 in proceeds. The notes are convertible beginning three months after the date of issuance, and the conversion price will be the lower of a 15% discount to (i) the 5-day volume-weighted average price (“VWAP”) immediately prior to Closing or (ii) the price of any offering entered into by the Company during the term of the notes. The Company has the option to prepay the notes at any time for 107% of total outstanding balance and any outstanding principal will be paid in conversion of shares of common stock at the end of the term, subject to the Company’s exercise of the optional prepayment right. Any accrued interest will be repaid quarterly in cash. The Company also issued warrants to the lenders to purchase an aggregate 240,917 shares of common stock, exercisable at $1.40 per share, with such warrants expiring five years from issuance. In addition, the Company’s Chief Executive Officer, Dr. Anatoly Dritschilo, invested a total of $237,500 in this financing round, in exchange for a $250,000 convertible note.
On October 21, 2024, the Company issued an additional $231,579 in senior secured convertible notes due in October 2025, with substantially similar terms as the October 14, 2024, issuance. The notes include a 5% original issue discount and the Company received $220,000 in proceeds. The Company also issued warrants to the lenders to purchase an aggregate 88,544 shares of common stock, exercisable at $1.49 per share, with such warrants expiring five years from issuance. Upon completing this issuance, the Company closed the senior secured convertible note offering after receiving a total of $790,000 in proceeds.
After analyzing the terms of the 2024 Convertible Bridge Notes (“Convertible Bridge Notes”) and its embedded features, the Company elected to account for the 2024 Convertible Bridge Notes at fair value under the allowable fair value option election. As such, the Company initially recognized the 2024 Convertible Bridge Notes at their fair value and will subsequently measure the note at fair value with changes in fair value recorded in current period earnings (or other comprehensive income, if specific to Company credit risk). The Company initially recorded the 2024 Convertible Bridge Notes at their estimated issuance date fair value of $806,758. As the fair value of the 2024 Convertible Bridge Notes exceeded the proceeds received, the Company recorded a loss on issuance of convertible notes of $16,758, which is included as a finance fee on the consolidated statement of operations. The proceeds were allocated in full to the 2024 Convertible Bridge Notes recorded at fair value. The warrants issued in connection with the 2024 Convertible Bridge Notes were deemed to be equity instruments. In addition, the Company allocated the issuance costs incurred to these instruments to the 2024 Convertible Bridge Notes and as such, expensed $107,491 in issuance costs during the year ended December 31, 2024, including $41,579 of original issue discount on the 2024 Convertible Bridge Notes.
The Company used a Monte Carlo simulation model to calculate the fair value of the 2024 Convertible Bridge Notes and the related warrants as of the issuance date and for the 2024 Convertible Bridge Notes as of December 31, 2024. These financial instruments were classified within Level 3 of the fair value hierarchy at the initial measurement date, due to the use of unobservable inputs. The key inputs into the model were as follows at issuance and December 31, 2024:

Alto Opportunity Master Fund, SPC
On January 11, 2023, the Company entered into a securities purchase agreement (the “SPA”) with Alto Opportunity Master Fund, SPC - Segregated Master Portfolio B, a Cayman entity (the “Investor”), pursuant to which the Company sold to the Investor a $4,300,000 convertible note (the “Alto Convertible Note”) and warrant (the “Alto Warrant”) to purchase 127,260 shares of common stock, exercisable at $18.80 per share, in exchange for gross proceeds of $3,935,000 (the “Investment Amount”) (See Note 6). As a consequence of the Company issuing the Convertible Bridge Notes, the exercise price of the Alto Warrant was adjusted to $0.48 per share. The Company determined that the Alto Warrant contains a net cash settlement feature at inception and categorized the Alto Warrant as a liability in the accompanying consolidated financial statements. The Alto Convertible Note was amortized on a monthly basis and the Company could make such monthly amortization payments in cash or, subject to certain equity conditions, in registered shares of common stock or a combination thereof. Installments could be deferred by the noteholder, resulting in a variable interest rate. However, the effective interest rate was approximately 214% based on the internal rate of return calculated on a series of cash flows that occur at regular intervals. For equity repayment, the Alto Convertible Note was convertible into shares of common stock at a price per share equal to the lower of (i) $18.80 per share, as adjusted, (ii) 90% of the three lowest daily VWAPs of the 15 trading days prior to the payment date, or (iii) 90% of the VWAP of the trading day prior to payment date. The noteholder was able to be convert at any time at a fixed price of $18.80 per share, as adjusted. The noteholder had an acceleration of installment amount conversion option (the “Alto Acceleration Option”), whereby the noteholder, with certain share percentage limitations, could convert to common stock any outstanding installment amount at an amount equal to the installment amount plus five times (5x) the installment amount at any time. The Company determined the Alto Acceleration Option was an embedded derivative within the host instrument and bifurcated it from the host instrument and recorded it as a derivative liability valued at $1,442,000 at inception, using a Monte Carlo simulation model (Note 7). The Convertible Note was repayable over 26 months and bore interest at the rate of 5% per annum. Additionally, the note contained certain redemption options and “Make Whole” provisions.
In conjunction with entry into the SPA, the Company entered into a series of related agreements, including a security agreement (the “Security Agreement”), an intellectual property security agreement (the “IP Security Agreement”) and a subsidiary guaranty (the “Subsidiary Guaranty”). The security agreements and guaranty allow, among other things, for the Investor to have a security interest in and place a lien on all of the Company’s assets and intellectual property until such time as the Alto Convertible Note is paid off. In addition, the SPA called for the Company to enter into a springing deposit account control agreement (the “Springing DACA”), which, in the event the Company defaulted on its repayment of the Alto Convertible Note, would allow the Investor to assume control of the Company’s bank account only with regard to any funds remaining outstanding under the Alto Convertible Note. As such, in conjunction with entry into the SPA, the Company established a separate bank account in which it deposited the Investment Amount and pursuant to which the Company, the Investor and the bank holding the Investment Amount, First Republic Bank, entered into the Springing DACA agreement. As the Investment Amount had been held at First Republic Bank, in light of certain banking crises then affecting smaller banks, on March 12, 2023, the Company and the Investor moved the Investment Amount from First Republic Bank, after which time the Springing DACA was no longer in effect. Further, pursuant to amendments to the SPA entered into in May and June of 2023, the Company and the Investor agreed that all of the Investment Amount would be released to the Company and the relevant provision of the SPA which required the Springing DACA would no longer be deemed applicable. In addition, the Company granted the Investor the option to purchase up to an additional $10 million in convertible notes and warrants on substantially the same terms as the Alto Convertible Note and Alto Warrant, excluding the Springing DACA requirement, with such option to be effective through December 31, 2025. The agreement offered the investor an opportunity to participate in future capital raises at substantially similar terms as the January 11, 2023 agreement. The Company expected that such subsequent convertible notes and warrants would be issued on substantially similar terms as the January 11, 2023 initial agreement, as amended, thus providing the Company the opportunity to negotiate certain aspects of the agreement.
Boustead Securities, LLC (“Boustead”) served as a placement agent for the Alto Convertible Note and Warrant offering and received $345,000 cash compensation and a warrant to purchase 8,909 shares of common stock, exercisable at $18.80 per share, as adjusted. The Boustead warrant was determined to be an equity instrument valued on a non-recurring basis. The Company used the Black Scholes valuation model using a term of five years, volatility of 110%, a risk-free rate of 3.53% for a value of $99,543.
The Company allocated the finance costs related to the Boustead placement agent fee of $345,000, based on the relative fair market values of the Convertible Note and warrants issued. The allocation of the financing costs applied $232,027 to the debt component as a debt discount that was being amortized to interest expense over the term of the Convertible Note, $104,245 to the warrant derivative liability component, expensed as a finance fee, and $8,727 to the equity warrant as a reduction in additional paid in capital.
The Company allocated to the debt component of the note an original discount of $300,000, legal fees of $65,000, $215,000 for additional interest fees on day one added to note principal, $1,442,000 for the accelerated conversion feature, and $1,288,543 for the fair value of warrants, resulting in an additional $3,310,543 debt discount that was being amortized to interest expense over the term of the Alto Convertible Note.
On August 6, 2024, the Company entered into an amendment to the SPA with Alto. Under the Amendment Agreement, the Company and Alto agreed as follows: (i) that the Company would pay $600,000 (the “Cash Collateral”) in cash by wire transfer of immediately available funds to Alto, which would be held as collateral on the remaining $1.2 million outstanding under the Alto Note; (ii) Alto will defer the monthly installment payment due on September 3, 2024 under the Alto Note until the Alto Note’s March 11, 2025 maturity date; and (iii) Alto would grant a waiver of any default Section 4(a)(xvi) of the Note related to the restatement and reaudit of the Company’s financial statements for the years ended December 31, 2022 and 2023. The amendment was accounted for as a troubled debt restructuring as the Company determined it was experiencing financial difficulties and was provided a concession through the deferral of one monthly principal and interest payment. As the future undiscounted cash flows exceeded the carrying value of the Alto Convertible Note, the Company did not recognize any gain or loss associated with the troubled debt restructuring.
During the year ended December 31, 2024, the Company recorded interest expense of $1.2 million, which included amortization of debt discount of $1.1 million. During the year ended December 31, 2024, the Company settled $1.4 million of principal and settled $0.1 million of accrued interest, which settlements were made in the form of 797,345 shares of common stock. During the year ended December 31, 2024, the Company paid $0.8 million of principal and $0.1 million of accrued interest for a total of $0.9 million. In relation to the settlements described above, the convertible debt was settled by September 30, 2024 and the Company recognized a loss on settlement of convertible debt of $0.8 million.
During the year ended December 31, 2023, the Company recorded interest expense of $2.5 million, which included amortization of debt discount of $2.1 million. During the year ended December 31, 2023, the Company settled $1.9 million of principal and settled $0.3 million of accrued interest, which settlements were made in the form of 297,625 shares of common stock.

October 2024 Equity Financing
In July 2024, the Company entered into an agreement with A.G.P./Alliance Global Partners (“AGP”), as the exclusive underwriter, placement agent, or advisor in a public or private offering of up to $10,000,000 of the Company’s securities. Under the agreement, AGP was paid a $50,000 retainer fee.
On October 31, 2024, AGP served as lead underwriter along with Boustead as co-underwriter for the Company to consummate a public offering (the “Public Offering”) of an aggregate of (i) 395,574 shares of common stock (the “Common Stock”) and 2,555,246 pre-funded warrants to purchase up to 2,555,246 shares of common stock (the “Pre-Funded Warrants”), and (ii) 2,950,820 common stock purchase warrants to purchase up to 2,950,820 shares of common stock (the “Common Warrants”). Each share of common stock, or a pre-funded warrant in lieu thereof, was sold together with an accompanying warrant to purchase one share of common stock.
The public offering price for each share of Common Stock and one accompanying Common Warrant was $1.525. The public offering price of each Pre-Funded Warrant and one accompanying Common Warrant was $1.524, which equals the price at which one share of Common Stock and accompanying Common Warrant was sold to the public in this offering, minus $0.001. The exercise price of each Pre-Funded Warrant is $0.001 per share, until exercised. Each Common Warrant offered in the offering is exercisable for one share of Common Stock and has an initial exercise price equal to $1.40, over a five-year term. The Company received aggregate gross proceeds from the offering of approximately $4.5 million, before deducting placement agents’ fees and other offering expenses, of $0.8 million.
Both the Pre-Funded Warrants and the Common Warrants contain standard adjustments to the exercise price, including for stock splits, stock dividends and pro rata distributions and contain customary terms regarding the treatment of such Pre-Funded Warrants or Common Warrants in the event of a fundamental transaction, which include but are not limited to a merger or consolidation involving the Company, a sale of all or substantially all of the assets of the Company or a business combination resulting in any person acquiring more than 50% of the outstanding shares of Common Stock of the Company. Additionally, the Pre-Funded Warrants and Common Warrants include restrictions on exercise in the event the Purchaser’s beneficial ownership of the Company’s common stock would exceed 4.99% of the number of shares of Common Stock outstanding immediately after giving effect to the exercise.
The Company concluded that the Pre-Funded Warrants met the requirements to be classified in stockholders’ equity. The Common Warrants will be classified as liabilities as they do not meet the requirements to be considered indexed to the Company’s own stock, due to potential variability in the settlement amount upon a fundamental transaction. The fair market value of the Common Warrants and the Pre-Funded Warrants at their issuance has been calculated using a Monte Carlo simulation model. The key inputs into the model were the same used for the 2024 Convertible Bridge Notes (Note 5 above), except for the risk-free rates (4.15% - 4.47%), respective exercise prices and expected lives. The net proceeds from the Public Offering were allocated first to the Common Warrants at fair value, with the residual amount recorded to the Common Stock and Pre-Funded Warrants based on their relative fair value. The proceeds allocated to the Common Warrants, Common Stock and the Pre-Funded Warrants were $0.2 million, $0.8 million and $3.5 million, respectively. The estimated fair values of the Shares and Pre-Funded Warrants have been recorded in additional paid in capital, while the fair value of the Common Warrants have been recorded as a derivative liability.
The Company also incurred $0.8 million in legal and other fees related to the Public Offering. The legal and other fees were allocated to the Common Stock, Common Warrants, and Pre-Funded Warrants in proportion to the allocation of the proceeds. $0.7 million of legal and other fees are recorded as costs of the Public Offering and reduced the amount recorded to additional paid in capital, while less than $0.1 million of legal and other fees are recorded as expense.
Warrants
In connection with the January 2023 Alto Convertible Note, Boustead was granted warrants to purchase 8,909 shares of common stock, at an exercise price of $18.80 per share (Note 5). In addition, Alto was granted warrants to purchase 127,260 shares of common stock, at an exercise price of $0.48 per share, as adjusted (Note 5, 7).
In connection with the Convertible Bridge Notes issued on October 14, 2024, the lenders were granted warrants to purchase 240,917 shares of common stock, at an exercise price of $1.40 per share. In addition, in connection with the Convertible Bridge Notes issued on October 21, 2024, the lenders were granted warrants to purchase 88,544 shares of common stock, at an exercise price of $1.49 per share.
In connection with the October 2024 Equity Financing, the Company issued pre-funded warrants to purchase up to 2,555,246 shares of common stock, at an exercise price of $0.001 per share, and warrants to purchase up to 2,950,820 shares of common stock, at an exercise price of $1.40 per share. The table below excludes the pre-funded warrants, of which 729,246 were exercised during the year ended December 31, 2024. As of December 31, 2024, 1,826,000 pre-funded warrants remained unexercised and outstanding and have no expiration date.
A summary of activity regarding warrants to purchase common stock (excluding pre-funded warrants) for the year ended December 31, 2024 were as follows:
Schedule of Warrants Activity
Number of Weighted Average Average
warrants Exercise Price Life (years)
Outstanding, December 31, 2023 $ 184,000 $ 23.20 2.77
Granted 3,280,281 1.40 5.00
Outstanding, December 31, 2024 $ 3,464,281 $ 1.89 4.67
The intrinsic value of the warrants as of December 31, 2024 is less than $0.1 million. All of the outstanding warrants are exercisable as of December 31, 2024.
Equity Incentive Plan
The Company’s 2018 Equity Incentive Plan (the “2018 Plan”) provides for equity incentives to be granted to employees, executive officers, directors and key advisers and consultants. Equity incentive grants may be made in the form of stock options with an exercise price of not less than the fair market value of the underlying shares as determined pursuant to the 2018 Plan, restricted stock awards, other stock-based awards, or any combination of the foregoing. The 2018 Plan is administered by the Company’s compensation committee. The Company has reserved 3,000,000 shares of common stock for issuance under the 2018 Plan. As of December 31, 2024, 1,174,684 shares have been granted, net of forfeitures, under the 2018 Equity Incentive Plan, of which 90,045 shares have vested.
Restricted Stock Units
The Company may grant restricted stock units (“RSU”) under our 2018 Plan. RSUs are bookkeeping entries representing an amount equal to the fair market value of one share of our common stock. Subject to the provisions of the 2018 Plan, the administrator determines the terms and conditions of RSUs, including the vesting criteria and the form and timing of payment. Notwithstanding the foregoing, the administrator, in its sole discretion, may accelerate the time at which any restrictions will lapse or be removed. RSUs granted typically vest annually in one third increments from the date of appointment.
During the years ended December 31, 2024 and 2023, pursuant to agreements with directors, officers and consultants, 1,102,410 and 32,415 RSUs with a value of $0.9 million and $0.4 million were granted, respectively. Compensation expense for the vesting RSUs were as follows:

Rights Offering and Financing Commitment
On February 7, 2024, the Company and its wholly-owned subsidiary, Shuttle Diagnostics, Inc., entered into a securities purchase agreement (the “Purchase Agreement”) with SRO, LLC, a Nevada limited liability company, pursuant to which SRO LLC agreed to commit to purchasing from the Company $2,250,000 of units from the Company, with each Unit consisting of (i) one share of the Company’s common stock, (ii) a warrant to purchase one share of the Company’s common stock exercisable at a purchase price of $18.80 per share, and (iii) a percentage of equity interest in Diagnostics such that, assuming the sale of all $2,250,000 of Units, SRO LLC will own a 22% interest in Diagnostics. The Company filed an initial registration statement on Form S-1 (the “Form S-1”) with the SEC in April 2024 related to the registration of subscription rights to purchase the Units to be sold in the Rights Offering. The Company incurred $142,000 of costs which were expensed during the year ended December 31, 2024 due to delays in consummating the Rights Offering. In January 2025, the Company withdrew the registration statement on Form S-1 for this offering. The registration statement was never effective and no securities were issued pursuant to the registration statement.
Note 7 - Derivative Liabilities
Fair Value Assumptions Used in Accounting for Derivative Liabilities
ASC 815 requires the Company to assess the fair market value of derivative liabilities at the end of each reporting period and recognize any change in the fair market value as other income or expense.
In October 2024, in connection with the Equity Financing, the Company issued warrants to purchase 2,950,820 shares of common stock, with an exercise price of $1.40 per share, valued at inception at $0.2 million and as of December 31, 2024, at less than $0.1 million. The Company determined that the derivative liabilities from the warrants issued in relation to the October 2024 Equity Financing did not qualify for classification as equity instruments as they did not meet the requirements to be considered indexed to the Company’s own stock, due to potential variability in the settlement amount upon a fundamental transaction, as defined.
In January 2023, in connection with the Alto Convertible Note, the Company issued warrants to purchase 127,260 shares of common stock, with an exercise price of $0.48 per share, as adjusted, valued at inception at $1.2 million and as of December 31, 2024, at less than $0.1 million. The Company determined that the derivative liabilities from the warrants issued in relation to the Alto Convertible Note did not qualify for classification as equity instruments due to the existence of certain net cash settlement provisions that are not within the sole control of the Company. In addition, there are certain down round provisions that could reduce the exercise price if the Company issues securities at lower prices in the future.
The Company has determined the Acceleration Option in the Alto warrants is an embedded derivative within the host instrument and has bifurcated it from the host instrument and recorded it as a derivative liability valued at $1.4 million at inception, using a Monte Carlo simulation model. The Company determined its derivative liability from the noteholder’s Acceleration Option for the Alto Convertible Note is not clearly and closely related to the host and should thus be accounted for as a bifurcated derivative liability. As of December 31, 2024, the value of the Acceleration Option was $0 as the Alto Convertible Note was settled by September 30, 2024.
The Company classifies these derivative liabilities as a Level 3 fair value measurement and used the Monte Carlo pricing model to calculate the fair value as of December 31, 2024 (less than $0.1 million) and December 31, 2023 ($0.4 million).
The key inputs for the Monte Carlo simulation* for the Alto and October 2024 Equity Financing warrants as of December 31, 2024, were as follows:

Note 9 - Business Segment Information
The Company operates as one operating segment with a focus on products designed to address the limitations of the current cancer therapies as well as to extend to the new applications of radiation therapy. The CEO, as our chief operating decision maker (CODM), manages and allocates resources to the operations of the Company on a consolidated basis, considering primarily research and development expenditures, cash burn and net loss. This enables the CEO to assess our overall level of available resources and determine how best to deploy these resources across products and research and development projects in line with the longer-term Company-wide strategic goals.
The accounting policies of our reportable segment are the same as those described in the “Summary of Significant Accounting Policies” for the Company. All costs, research and development expenses, general and administrative expenses, other operating expenses, interest expense, depreciation, corporate overhead assets (workforce, intellectual property, etc.) are fully allocated to the Company’s one segment. Significant segment expenses include payroll and costs incurred for the Company’s primary third-party contract research organization (“CRO”). During the years ended December 31, 2024 and 2023, the Company incurred payroll expenses classified in our consolidated statements of operations as research and development of $1.0 million and $1.3 million, respectively. During the years ended December 31, 2024 and 2023, the Company incurred payroll expenses classified in our consolidated statements of operations as general and administrative of $0.5 million and $0.4 million. During the years ended December 31, 2024 and 2023, the Company incurred third-party CRO expenses of $2.1 million and $0.1 million, respectively, all of which is classified in our consolidated statements of operations as research and development. All other operating expenses in our consolidated statements of operations are characterized as other segment expenses which, after factoring in other income and expenses, reconcile to net loss for each period. The Company’s reportable segment’s profit or loss, assets, significant expenses and other specified items are consistent with the financial information disclosed in our consolidated financial statements. See the consolidated financial statements for the financial information of the Company’s one segment.

The Company paid TCG GreenChem a total of $1,096,370 during the year ended December 31, 2023, completing the contract. No costs were incurred during the year ended December 31, 2024 with this related party.
Note 12 - Income Taxes
The Company has no income tax expense or benefit for the years ended December 31, 2024 and 2023, since the Company has a full valuation allowance for the net operating loss carryforwards in these periods.
The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized from such positions are estimated based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. There are no uncertain tax positions to be reported for the tax years 2024 and 2023.
The Tax Cuts and Jobs Act of 2017 (“TCJA”) amended IRC Section 174 to require capitalization of all research and development (“R&D”) costs incurred in tax years beginning after December 31, 2021. These costs are required to be amortized over five years if the R&D activities are performed in the U.S., or over 15 years if the activities were performed outside the U.S. For tax reporting purposes, the Company capitalized $3,543,023 and $3,517,485 of R&D expenses incurred as of December 31, 2024 and 2023, respectively.
The reconciliation of income tax benefit at the U.S. statutory rate of 21% to the Company’s tax expense is as follows:

As of December 31, 2024 and 2023, the Company had approximately $10.9 million and $6.4 million of net operating losses (“NOL”) carried forward to offset federal and state taxable income, if any, in the future, respectively. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. Based on the assessment, management has established a full valuation allowance against all of the deferred tax asset relating to NOLs for every period because it is more likely than not that all of the deferred tax asset will not be realized.
NOLs created prior to 2018 could be carried back two years and carried forward 20 years. As amended by the Tax Cuts and Jobs Act of 2017 (TCJA), NOLs created after 2017 can no longer be carried back and are instead carried forward indefinitely. The Company has $139,813 and $238,380 of federal NOL carryforwards from 2016 and 2017, respectively, which begin to expire in 2036. The Company has an additional $10.6 million and $10.9 million of federal and state NOLs created after 2017, respectively, which can be carried forward indefinitely. The NOLs can be used to offset future income limited to the lesser of the NOL or 80% of the year’s taxable income.
As of December 31, 2024, the Company has $200,715 of federal Research and Development (R&D) tax credits. These can be carried forward 20 years to offset future federal income tax. These begin to expire in 2037.
Note 13 - Subsequent Events
In January 2025, the Company entered into a change order to its existing agreement with Theradex Systems, Inc., the Company’s primary third-party CRO, for purposes of supporting the Company’s clinical trials of Ropidoxuridine. Following the change order, the Company’s total cost limit increased by $3.0 million, for an aggregate of $5.3 million, of which $3.2 million has not yet been incurred.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS
Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
On March 21, 2023, the Company’s audit committee selected Forvis Mazars, LLP (the “New Accountant”) to serve as the Company’s independent registered public accounting firm for the review of its Quarterly Reports on Form 10-Q and Annual Report on Form 10-K for the year ending December 31, 2023. As a result, the audit committee determined that BF Borgers CPA PC (the “Former Accountant”) would no longer serve as the Company’s independent registered public accounting firm, effective as of March 21, 2023.
On March 22, 2023, the Company filed a Current Report on Form 8-K (the “Original Form 8-K”) with the SEC disclosing the changes in its certifying accountant.
As disclosed in the Original Form 8-K, the Former Accountant’s audit report on our financial statements for the years ended December 31, 2021 and 2022 contained no adverse opinion or disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope or accounting principles, except that the audit report on the financial statements of the Company for the year ended December 31, 2021 contained an uncertainty about the Company’s ability to continue as a going concern (the “Going Concern Opinion”). The Former Auditor’s Going Concern Opinion was resolved following the Company’s completion of its approximately $11.4 million initial public offering in September 2022 and subsequent $4.0 million private placement in January 2023.
When the Former Accountant was engaged through its dismissal in March 2023, for the years ended December 31, 2022 and 2021 and through the date of the Original Form 8-K, the Company had no “disagreements” (as defined in Regulation S-K, Item 304(a)(1)(iv) and the related instructions) with the Former Accountant on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to the satisfaction of the Former Accountant would have caused them to make reference thereto in their reports on the financial statements for such periods.
There were no reportable events for the years ended December 31, 2022 or 2021 and through the date of the Original Form 8-K, there were no reportable events as defined in item 304(a)(1)(v) of Regulation S-K.
As also disclosed in the Form 8-K, prior to retaining the New Accountant, the Company did not consult with the New Accountant regarding either: (i) the application of accounting principles to a specified transaction, either contemplated or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements; or (ii) any matter that was the subject of a “disagreement” or a “reportable event” (as those terms are defined in Item 304(a)(1)(iv) and (a)(1)(v) of Regulation S-K, respectively).
On March 21, 2023, the Company provided the Former Accountant with the disclosures contained in the Form 8-K disclosing the dismissal of the Former Accountant and requested in writing that the Former Accountant furnish the Company with a letter addressed to the SEC stating whether or not they agree with such disclosures. The Former Accountant’s response was filed as Exhibit 16.1 to the Original Form 8-K.
On May 3, 2024, the SEC entered a cease-and-desist order against our Former Accountant, which resulted in the Re-audit of our financial statements for the year ended December 31, 2022, which had been audited by our Former Accountant. Since that time and as a result of the Re-audit, as of July 10, 2024, the Company and the audit committee of our board of directors, in consultation with our current auditor, Forvis Mazars LLP, concluded that our audited financial statements for the year ended December 31, 2022, our audited financial statements for the year ended December 31, 2023 and the quarterly periods included in the Company’s 2023 Form 10-K, and the Quarterly Report on Form 10-Q for the period ended March 31, 2024, required restatement and were not reliable. We reported this determination in our Form 8-K filed on July 16, 2024 and subsequently filed an Annual Report on Form 10-K/A amending the Company’s 2023 Form 10-K and a Quarterly Report on form 10-Q/A amending the Company’s Form 10-Q for the period ended March 31, 2024, which reports were each filed on September 4, 2024.

ITEM 9A. CONTROLS AND PROCEDURES
Item 9A. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures (as defined in Exchange Act Rule 15d-15(e)) are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Exchange Act, such as this report, is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures are also designed with the objective of ensuring that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
As of December 31, 2024, our management carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures. Such evaluation was carried out under the supervision of our Chief Executive Officer by our Chief Financial Officer with the assistance of our Vice Present of Regulations, our President and Chief Operating Officer, and our third-party consultants. Based on this evaluation, management concluded that our disclosure controls and procedures were, and continues to be, ineffective as of December 31, 2024. Based on the foregoing, our management concluded that our internal controls over the following financial reporting areas to be material weaknesses:
● Our written accounting policies and documentation of management’s contemplation of the accounting treatment and implications over significant unusual transactions, including complex accounting associated with debt and equity transactions, was limited and resulted in ineffective monitoring of financial reporting. These were contributing factors which lead to untimely filings.
● Our written policies and procedures over accounting transaction processing and period end financial close and reporting are limited, which has resulted in ineffective oversight in the establishment of proper monitoring controls over accounting and financial reporting; in addition, we lacked sufficient review and segregation of duties for certain financial transactions, manual journal entries, and critical financial spreadsheets, such that a proper review had not been performed by someone other than preparer, and that process documentation is lacking for review and monitoring controls over accounting and financial reporting. These were contributing factors which led to untimely filings for certain periods in fiscal year 2024.
● We lack a formal process to identify and ensure the proper classification of operating expenses as Research and Development.
● We identified findings related to overall information technology general controls (“ITGCs”) including issues with super-user access and segregation of duties for systems supporting the Company’s internal control processes and controls.
● Our accounting policies and review processes regarding certain technical aspects of financial reporting for stock-based compensation transactions, particularly relating to grant date fair value and expense attribution, was not performed at a sufficiently precise level and resulted in the incorrect recording of related compensation expense and related disclosures.
Other than as noted below, there has been no change in the Company’s internal control over financial reporting during the fiscal year ended December 31, 2024 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. Management will continue to monitor and evaluate the effectiveness of our internal controls and procedures over financial reporting on an ongoing basis and are committed to taking further action and implementing additional improvements as necessary.
Management’s Remediation Measures
While the Company has improved its organizational capabilities, the Company’s remediation efforts will continue to take place. Management is committed to maintaining a strong internal control environment. In response to the identified material weaknesses in the overall control environment, management is currently implementing additional measures which include:
● Hired a new Chief Financial Officer during the second quarter of 2024 to bolster the Company’s internal technical accounting and financial reporting experience and provide bandwidth for the prior Chief Financial Officer to focus on the Company’s expanding clinical trial.
● Engaged a third-party consulting firm to assist with the preparation of SEC reporting and other technical accounting matters.
The Company will continue to review and improve its internal controls over financial reporting to address the underlying causes of the material weaknesses and control deficiencies. While the Company has added significant resources, particularly relevant to unusual and complex accounting matters, and stock-based compensation accounting and reporting, its material weaknesses and control deficiencies will not be fully remediated until the Company has concluded that its internal controls are operating effectively for a sufficient period of time.

Board of Directors
Our board of directors is responsible for overseeing the Company’s business consistent with its fiduciary duty to the stockholders. This significant responsibility requires highly skilled individuals with various qualities, attributes and professional experience. There are general requirements for service on the board of directors that are applicable to directors and there are other skills and experience that should be represented on the board of directors as a whole but not necessarily by each director. Our corporate governance and nominating committee, detailed below, considers the qualifications of director candidates individually and in the broader context of the board of directors’ overall composition and the Company’s current and future needs.

All of our directors are elected to one-year terms to hold office until the next annual meeting of our stockholders and until a successor is appointed and qualified, or until their removal, resignation, or death. Executive officers serve at the pleasure of the board of directors.
Director Independence
In order to qualify for continued listing on Nasdaq, our board of directors must consist of a majority of “independent” directors, as defined under Nasdaq listing standards and Rule 10A-3(b)(1) under the Exchange Act.

Board Committees
General
Our board of directors has established three committees consisting of an audit committee, a compensation committee, and a nominating and corporate governance committee.

Code of Ethics
We have adopted a code of ethics that applies to all of our executive officers, directors and employees. The code of ethics codifies the business and ethical principles that govern all aspects of our business. This document will be made available in print, free of charge, to any stockholder requesting a copy in writing from our secretary at our executive offices in Gaithersburg, Maryland. A copy of our code of ethics is available on our website at www.shuttlepharma.com.
Insider Trading Policies and Procedures
The Company has adopted an insider trading policy, as amended and restated on March 10, 2023 (the “Insider Trading Policy”), overseen by the Company’s corporate secretary, that applies to all (i) directors, (ii) executive officers and (iii) employees who are exposed to insider information (together, the “Covered Persons”). The Insider Trading Policy prohibits the use of material non-public information obtained by Covered Persons through their involvement with the Company when making decisions to purchase, sell, give away or otherwise trade in the Company’s securities or to provide such information to others outside the organization. Under the Insider Trading Policy, material non-public information includes, among other things, significant changes in the Company’s prospects, significant write-downs, liquidity problems, changes in management, extraordinary borrowings, changes in debt, planned public offerings or any other information that may be deemed material to the Company or the Company’s prospects. Further, we have established black-out periods to which all Covered Persons are subject, including quarterly black-out periods, which commence three weeks before the end of each quarter and continue until the quarterly results are disclosed by filing the Company’s Quarterly Report on Form 10-Q or Annual Report on Form 10-K. The Company may impose black-out periods from time to time as other types of material non-public information occur when material non-public events or disclosures are pending. If the Company imposes a special black-out period, the Company will notify Covered Persons accordingly. Covered Persons are permitted to trade in the Company’s securities only when there is no black-out period in effect and such trade has been pre-cleared by the Company’s corporate secretary, or when a qualified 10b5-1 plan has been established in accordance with federal securities laws.
Clawback Policy
While the Company does not presently have in place any significant incentive compensation agreements or awards tied to the Company’s overall financial performance, the Company’s board of directors has adopted a clawback policy in order to comply with federal securities laws. As such, we have adopted a clawback policy in which we may seek the recovery or forfeiture of incentive compensation paid by us, including cash, equity or equity-based compensation, in the event we restate our financial statements under certain circumstances. The clawback policy applies to our Section 16 officers, any employee who was eligible to receive incentive compensation and whose conduct contributed to the need for a restatement, and any other former Section 16 officer or other employee who contributed to the need for such restatement.
Board of Directors Role in Risk Oversight
Members of the board of directors have periodic meetings with management and the Company’s independent auditors to perform risk oversight with respect to the Company’s internal control processes. The Company believes that the board of directors’ role in risk oversight does not materially affect the leadership structure of the Company. The Company believes that its founders, leadership team and members of the board of directors exemplify diversity and inclusivity with respect to race, sex and ethnic origin.
Section 16(A) Beneficial Ownership Reporting Compliance
Section 16(a) of the Exchange Act requires our executive officers and directors, and persons who own more than 10% of our common stock, to file reports regarding ownership of, and transactions in, our securities with the SEC and to provide us with copies of those filings. Based solely on our review of the copies of such forms furnished to us and written representations by our officers and directors regarding their compliance with applicable reporting requirements under Section 16(a) of the Exchange Act, we believe that all Section 16(a) filing requirements for our executive officers, directors and 10% stockholders were met during the year ended December 31, 2024, except for the following:
