Overview PART I We are a clinical stage gene therapy company pioneering the development of gene-based therapies for large patient populations with unmet medical needs. Our oncology platform utilizes our systemic, non-viral ONCOPREX® Delivery System which uses lipid-based nanoparticles in a lipoplex form to deliver tumor suppressor gene-expressing plasmids to cancer cells. The product is administered intravenously, where it is taken up by tumor cells that then express tumor suppressor proteins that were deficient in the tumor. Our diabetes technology is designed to work in Type 1 diabetes by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In Type 2 diabetes, our technology is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin. Oncology Platform Our lead oncology drug candidate, REQORSA® Immunogene Therapy (generic name: quaratusugene ozeplasmid), previously referred to as GPX-001, is initially being developed in combination with prominent, approved cancer drugs to treat Non-Small Cell Lung Cancer (“NSCLC”) and Small Cell Lung Cancer (“SCLC”). REQORSA has a multimodal mechanism of action whereby it interrupts cell signaling pathways that cause replication and proliferation of cancer cells, re-establishes pathways for apoptosis, or programmed cell death, in cancer cells, and modulates the immune response against cancer cells. In early studies, REQORSA has been shown to be complementary with targeted drugs and immunotherapies. Our strategy is to develop REQORSA in combination with current approved therapies and we believe REQORSA’s unique attributes position it to provide treatments that improve on these current therapies for patients with NSCLC, SCLC, and possibly other cancers. Acclaim – 1: We currently are enrolling and treating patients in the Phase 2a expansion portion of our Phase 1/2 Acclaim-1 clinical trial. The Acclaim-1 trial uses a combination of REQORSA and AstraZeneca’s Tagrisso® in patients with late-stage NSCLC that has activating epidermal growth factor receptor (“EGFR”) mutations and progression after treatment with Tagrisso. Following the May 2023 completion of the Phase 1 dose escalation portion of the study, the Acclaim-1 Safety Review Committee (“Acclaim-1 SRC”) approved advancement from the Phase 1 dose escalation portion to the Phase 2a expansion portion of the study. Based on a review of safety data which showed no dose limiting toxicities (“DLTs”), the Acclaim-1 SRC determined that the recommended Phase 2 dose (“RP2D”) of REQORSA will be 0.12 mg/kg. This was the highest dose level delivered in the Phase 1 portion of the study and is twice the highest dose level delivered in the Company’s prior clinical trial combining REQORSA with Tarceva® for the treatment of late-stage lung cancer. We opened the Phase 2a expansion portion of the study and enrolled and dosed the first patient in January 2024. The Phase 2a expansion portion of the trial is expected to enroll approximately 66 patients; half will be patients who received only prior Tagrisso treatment and the other half will be patients who received prior Tagrisso treatment and chemotherapy. The aim is to determine toxicity and efficacy profiles of patients with different eligibility criteria. There will be an interim analysis following the treatment of 19 patients in each cohort. We expect to complete the enrollment of 19 patients in each cohort of the Phase 2a expansion portion of the study by the end of 2024, and thus we expect the interim analyses in early 2025. The Food and Drug Administration (“FDA”) has granted Fast Track Designation for the Acclaim-1 treatment combination of REQORSA and Tagrisso in NSCLC patients who have progressed after Tagrisso treatment. Acclaim – 2: We currently are enrolling and treating patients in the Phase 1 dose escalation portion of our Phase 1/2 Acclaim-2 clinical trial. The Acclaim-2 trial uses a combination of REQORSA and Merck & Co.’s Keytruda® in patients with late-stage NSCLC whose disease has progressed after treatment with Keytruda. Patients are currently being treated at the 0.06 mg/kg dose level in the first cohort of patients and, subject to Acclaim-2 Safety Review Committee (“Acclaim-2 SRC”) approval, will be treated at successive dose levels of 0.09 mg/kg and 0.12 mg/kg. In March 2023, we amended the Acclaim-2 protocol to include additional treatments in the control group with the goal of accelerating enrollment in the study by making the trial more attractive to a wider variety of investigators. We expect enrollment in the dose escalation portion of the study to be completed in the second half of 2024. We will then initiate and evaluate patients in the Phase 2a expansion portion of the study at the maximum tolerated dose (the “MTD”) or RP2D. The FDA has granted Fast Track Designation for the Acclaim-2 treatment combination of REQORSA and Keytruda in NSCLC patients who have progressed after Keytruda treatment. The expansion portion of both the Acclaim-1 and Acclaim-2 trials are Phase 2 studies. The expansion portion of these studies provides us the advantage of early insight into drug effectiveness in defined and distinct patient populations at the MTD or RP2D in order to better evaluate efficacy and increase the likelihood of a successful randomized Phase 2 trial which will follow the expansion portion of each study. Acclaim – 3: We currently are enrolling patients in the Phase 1 dose escalation portion of our Phase 1/2 Acclaim-3 clinical trial. The Acclaim-3 clinical trial uses a combination of REQORSA and Genentech, Inc.’s Tecentriq® as maintenance therapy in patients with extensive stage small cell lung cancer (“ES-SCLC”) who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. Patients are treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. In January 2024, we opened the Phase 1 portion of the Acclaim-3 study for enrollment. We expect to complete the Phase 1 dose escalation portion of the study during the second half of 2024 and we expect to start the Phase 2 expansion portion of our Acclaim-3 study in the second half of 2024. In June 2023, the FDA granted Fast Track Designation for the Acclaim-3 treatment combination of REQORSA and Tecentriq as maintenance therapy in patients with ES-SCLC who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. In August 2023, the FDA granted Orphan Drug Designation to REQORSA for the treatment of SCLC. The TUSC2 gene, which is the key component of REQORSA and plays a vital role in cancer suppression and normal cell regulation, is one of a series of genes on the short arm of Chromosome 3 whose therapeutic use is covered by our exclusive worldwide licenses from The University of Texas MD Anderson Cancer Center (“MD Anderson”). We believe that our ONCOPREX Delivery System allows for delivery of a number of cancer-fighting genes, alone or in combination with other cancer therapies, to combat multiple types of cancer and we are in early stages of discovery programs to identify other cancer candidates. In August 2022, we entered into a three-year sponsored research agreement with MD Anderson to support further preclinical studies of TUSC2 and other tumor suppressor genes. Diabetes Gene Therapy In diabetes, we have exclusively licensed from the University of Pittsburgh of the Commonwealth System of Higher Education (“University of Pittsburgh”) multiple technologies relating to the development of a gene therapy product for each of Type 1 and Type 2 diabetes. The same general novel approach is used in each of Type 1 and Type 2 diabetes whereby an adeno-associated virus (“AAV”) vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. In humans, this can be done with a routine endoscopy procedure. Our diabetes product candidates are currently being evaluated and optimized in preclinical studies at the University of Pittsburgh. GPX-002 is being developed using the same construct for the treatment of both Type 1 diabetes and Type 2 diabetes. GPX-002 for Type 1 diabetes is designed to work by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In a similar approach, GPX- 002 for Type 2 diabetes (formerly known as GPX-003), where autoimmunity is not at play, is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin. We finalized the components of the diabetes construct to take forward for nonclinical studies and in December 2023, we submitted a request to meet with the FDA to obtain their guidance on the nonclinical studies needed to file an Investigational New Drug (“IND”) application and initiate first-in-human studies. As a result of the FDA’s response, the Company will continue with its planned additional nonclinical studies before requesting regulatory guidance in 2024 for the IND-enabling studies. In October 2023, we entered into a one-year extension to our August 2022 sponsored research agreement with the University of Pittsburgh for the use of GPX-002 in a non-human primate (“NHP”) model in Type 2 diabetes. The extension includes a revised research plan to encompass our most recent technologies to which we acquired exclusive rights from the University of Pittsburgh in July 2023. These include a MafB promoter to drive expression of the Pdx1 and MafA transcription factors that can potentially be used for both Type 1 and Type 2 diabetes. See also “Note 7 – Commitments and Contingencies” to our financial statements included in this Annual Report on Form 10-K. In February 2023, the Company’s research collaborators at the University of Pittsburgh presented preclinical data in a NHP model of Type 1 diabetes highlighting the therapeutic potential of GPX-002 at the 16th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD 2023) in Berlin, Germany. The statistically significant study results showed the treated animals had decreased insulin requirements, increased c-peptide levels, and improved glucose tolerance compared to baseline. In April 2023, the Company hosted a Key Opinion Leader virtual event entitled “Novel Gene Therapy to Treat Type 1 Diabetes,” which discussed preclinical data reported at ATTD 2023 supporting gene therapy to treat Type 1 diabetes. Recent Developments At-the-Market Offering Program On December 13, 2023, we entered into an At The Market (“ATM”) Offering Agreement (the “Agreement”) with H.C. Wainwright & Co., LLC, serving as agent (the “Agent”) with respect to an ATM offering program under which we may offer and sell through the Agent, from time to time at our sole discretion, up to such number or dollar amount of shares (the “Shares”) of our common stock, par value $0.001 per share (the “Common Stock”), as registered on the prospectus supplement covering the ATM offering, as may be amended or supplemented from time to time. We have agreed to pay the Agent a commission equal to three percent (3%) of the gross sales proceeds of any Shares sold through the Agent under the Agreement, and also have provided the Agent with customary indemnification and contribution rights. As of December 31, 2023, we had not sold any Shares through the Agent under the Agreement. From January 1, 2024 through the date of filing of this Annual Report on Form 10-K, we have sold 158,474 shares of our common stock for net proceeds to us totaling $881,946 through the Agent under the Agreement. Reverse Stock Split At our special meeting of stockholders held on December 14, 2023, the Company’s stockholders adopted and approved an amendment to our Amended and Restated Certificate of Incorporation to effect a reverse stock split of our issued and outstanding shares of Common Stock, at a specific ratio, ranging from one-for-ten (1:10) to one-for-fifty (1:50), with such ratio to be determined by our Board in its discretion. On January 31, 2024, we filed the amendment to our Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware to effect a reverse stock split of our Common Stock at a ratio of one-for-forty (1:40) (the “Reverse Stock Split”). The Reverse Stock Split became effective in accordance with the terms of the amendment at 12:01 AM Eastern Time on February 2, 2024 under a new CUSIP number, 372446-203. All share and per share amounts in this Annual Report on Form 10-K have been adjusted to reflect the Reverse Stock Split. March 2024 Registered Direct Offering On March 21, 2024, we completed a registered direct offering, in which we sold to an institutional investor an aggregate of (i) 165,000 shares of our common stock, (ii) pre- funded warrants (the “March 2024 Pre-Funded Warrants”) exercisable for up to an aggregate of 1,377,112 shares of our common stock, and (iii) warrants (the “March 2024 Common Warrants”) exercisable for up to an aggregate of 1,542,112 shares of our common stock. The offering price for each share of common stock and accompanying March 2024 Common Warrant was $4.215, and the offering price for each March 2024 Pre-Funded Warrant and accompanying March 2024 Common Warrant was $4.2149. The March 2024 Pre-Funded Warrants are exercisable immediately upon issuance at an exercise price of $0.0001 per share and will expire when exercised in full. The March 2024 Common Warrants are exercisable immediately upon issuance at an exercise price of $4.09 per share and will expire in five years from the date of issuance. We received net proceeds of approximately $5.8 million after commissions and expenses, excluding any proceeds that may be received in the future from any exercise of the March 2024 Common Warrants. In connection with the offering, we also amended certain existing warrants to purchase up to an aggregate of 194,248 shares of our common stock that were previously issued to investors in March 2023 and July 2023, with exercise prices of $44.00 and $35.40 per share and expiration dates of March 1, 2028 and July 21, 2028 for $0.125 per amended warrant, such that the amended warrants have a reduced exercise price of $4.09 per share and an expiration date of five years from the closing of this offering. 2 Our Pipeline Our technologies are designed to administer disease-fighting genes to provide new therapies for large patient populations with cancer and diabetes who currently have limited treatment options. We are developing our lead oncology product candidate REQORSA to be administered with targeted therapies and with immunotherapies for NSCLC and SCLC. We continue to conduct preclinical research to explore how REQORSA may be administered with targeted therapies and immunotherapies in other solid tumors, such as ALK-positive NSCLC, and we are researching how other cancer fighting genes, such as NPRL2, can enhance our portfolio using our systemic, non-viral gene therapy platform, the ONCOPREX DeliverySystem. Using a different gene therapy delivery system, we are also developing our preclinical diabetes candidate GPX-002 using the same construct for both Type 1 diabetes and Type 2 diabetes (formerly known as GPX-003 when a different construct was being considered for Type 2 diabetes). The following table summarizes our product development pipeline. 3 Introduction – Cancer Cancer and Genetic Mutations. Cancer results from genetic mutations. Mutations that lead to cancer are usually present in two major classes of genes: oncogenes, which are involved in functions such as signal transduction and transcription; and tumor suppressor genes, which play multiple roles in governing cell growth and proliferation. Transduction is the process by which chemical and physical signals are transmitted into cells. In cancer cells, the oncogene mutations may overwhelm the natural tumor suppression processes, or those tumor suppression processes may be impaired or absent. Functional alterations due to mutations in oncogenes or tumor suppressor genes may result in the abnormal and uncontrolled growth patterns characteristic of cancer. These genetic alterations facilitate malignant growth by affecting signal transduction pathways and transcription, such as inhibiting normal growth signaling in the cell, circumventing the natural process of apoptosis, evading the immune system’s response to cancer, and inducing angiogenesis, which is the formation of new blood vessels that supply cancer cells. The most common genetic alterations present in lung cancer are in tumor suppressor genes. No targeted small molecule drugs have successfully been developed against tumor suppressor gene mutations in NSCLC or SCLC. Another genetic condition often associated with lung cancer is the presence of mutations of tyrosine kinases. Tyrosine kinases are enzymes that play an important role in signal transduction through the modification of proteins by adding phosphate groups (phosphorylation) onto the amino acid tyrosine, to change the proteins’ function. When an EGFR ligand binds to the EGFR, two EGFR transmembrane proteins are brought close together on the cell membrane surface, and the intracellular tyrosine kinase domains can autophosphorylate, and activate downstream processes, including cell signaling pathways that can lead to cell growth and proliferation. EGFRs can act similarly to a switch that turns “on” and “off” when phosphate groups are either added or taken away. Mutated kinases can have a malfunctioning on/off switch, causing the switch to be stuck in the “on” position leading to the loss of control of cell growth. Cancer and the Immune System. Cancer can also spread when the body’s natural immune functions are impaired, including by the cancer cells themselves. PD-1, or Programmed Death-1, is a receptor expressed on the surface of activated T cells, which are part of the body’s immune system. PD-L1 is a ligand for PD-1 which is expressed on the surface of cancer and other cells. The binding of PD-1 to PD-L1 has been speculated to contribute to cancer cells’ ability to evade the body’s immune response. PD-1 and similar molecules are called immune checkpoint inhibitors because they can impede the normal immune response, for example by blocking the T cells from attacking the cancer cells. In many cancers, PD-L1 is up-regulated. Substantial research has been performed in the emerging field of immuno-oncology to discover drugs or antibodies that could block PD-1 and similar receptors. It is believed that blocking the PD-1/PD-L1 interaction pathway and other similar checkpoints, such as cytotoxic T-lymphocyte-associated protein 4, or CTLA-4, with drugs called checkpoint inhibitors can prevent cancer cells from inactivating T cells, leading to an attack of the immune system on the cancer. Current Treatment of NSCLC. Chemotherapy is the standard treatment for the majority of NSCLC patients, as it is for many other cancer patients. Because it is a non- selective systemic treatment, rather than a targeted approach to treating cancer, chemotherapy also kills healthy cells and has a number of other undesirable side effects. A subset of NSCLC patients carry a mutation in EGFR, which makes their tumors sensitive to EGFR tyrosine kinase inhibitors (“EGFR TKIs”). The two most common are referred to as exon 19 deletion and exon 21 substitution. Several pharmacological and biological approaches, including EGFR TKIs, have been developed specifically to block activated EGFR for cancer therapy. EGFR TKI drugs are the most common targeted therapies used in lung cancer. Several EGFR TKI therapies are marketed commercially including, but not limited to, Tagrisso, Tarceva, Iressa and Gilotrif. Approximately 10% to 20% of NSCLC patients of North American and European descent and approximately 40% to 50% of NSCLC patients of Asian descent have activating EGFR mutations. This means that the majority of NSCLC patients do not have activating EGFR mutations and are therefore “EGFR negative” and not optimal candidates for EGFR TKIs. 4 In addition, even among those patients who are EGFR positive and benefit from EGFR TKI therapy, nearly all eventually become resistant to and ultimately no longer respond to EGFR TKI therapy, resulting in eventual disease progression. For example, according to the FLAURA study, sponsored by AstraZeneca, the median time to tumor progression for lung cancer patients on Tagrisso monotherapy is approximately 18 months. Furthermore, although recent clinical trials have shown that combining EGFR TKIs with conventional chemotherapy increases progression free survival for lung cancer patients with EGFR mutations compared to Tagrisso monotherapy, it is not yet clear whether the combination of Tagrisso and chemotherapy initially leads to longer overall survival than treatment with Tagrisso monotherapy (which has relatively few side effects) and then treatment with chemotherapy at the time of disease progression. Current Treatment of SCLC. SCLC is staged as limited stage, in which the cancer is only on one side of the chest and can be treated with a single radiation therapy field, or as extensive stage (ES), which includes all other patients. Since SCLC is an aggressive disease, the vast majority of patients have extensive stage SCLC at the time of initial diagnosis. The standard treatment for ES-SCLC for many years was a combination chemotherapy with carboplatin and etoposide for 4 cycles of treatment, as treatment with chemotherapy for longer duration or treatment including other agents was not shown to be beneficial. In the last several years the addition of immune checkpoint inhibitors has been shown to have improved efficacy when added to 4 cycles of chemotherapy. Thus, standard treatment now consists of either Tecentriq or Imfinzi added to 4 cycles of carboplatin and etoposide, and then Tecentriq or Imfinzi are continued as maintenance therapy until disease progression. However, treatment of ES-SCLC is not curative, and patients progress quickly. In patients receiving Tecentriq and chemotherapy, the progression free survival (“PFS”) after starting maintenance Tecentriq is only 2.6 months. Further improvements in the treatment of ES-SCLC are needed. Epidemiology of Lung Cancer. According to the World Health Organization in 2023, lung cancer was the leading cause of cancer deaths worldwide. According to the American Cancer Society in 2023, lung cancer accounts for about one in five of all cancer deaths in the United States, and causes more deaths in the U.S. with more people dying of lung cancer in the U.S. than of colon, breast and prostate cancers combined. In 2020, there were more than 2 million new lung cancer cases and approximately 1.8 million deaths from lung cancer worldwide. In the U.S., according to the American Cancer Society, it is estimated that in 2024 there will be more than 234,000 new cases of lung cancer and more than 125,000 deaths from this disease. NSCLC represents about 82% of all lung cancers and the five-year survival rate for patients with NSCLC with distant spread is 9 percent. SCLC represents about 14% of lung cancer patients and the five-year survival rate for patients with SCLC with distant spread is 3 percent. With limited benefit from current therapies, we believe there is a significant unmet medical need for new treatments for NSCLC and SCLC in the U.S. and globally, and we believe REQORSA may be suitable for the majority of lung cancer patients. REQORSA® REQORSA® immunogene therapy (generic name: quaratusugene ozeplasmid) is designed to (i) interrupt cell signaling pathways that cause replication and proliferation of cancer cells, (ii) target and kill cancer cells, and (iii) stimulate the natural immune responses against cancer. REQORSA is an immunogene therapy in that it combines features of gene therapy and immunotherapy. It up-regulates TUSC2 expression in the cell, and also increases the anti-tumor immune cell population and down-regulates PD-L1, thereby potentially boosting the immune response to cancer. REQORSA consists of a TUSC2 gene expressing plasmid encapsulated in non-viral lipid-based nanoparticles in a lipoplex form (our ONCOPREX Delivery System), which has a positive charge. REQORSA is injected intravenously and specifically targets cancer cells. Cancer cells have elevated metabolism compared to healthy cells and as a result, are negatively charged compared to healthy cells, which are generally charge neutral. REQORSA is designed to deliver the functioning TUSC2 gene to cancer cells while minimizing uptake by normal tissue. Laboratory studies conducted at MD Anderson show that the uptake of TUSC2 in tumor cells in vitro after REQORSA treatment was 10 to 33 times the uptake in normal cells. Biopsies in three patients with NSCLC treated with REQORSA show major increases in TUSC2 protein expression in the tumor cells one day after REQORSA administration. We believe that REQORSA is the first systemic gene therapy to be used for cancer in humans. Many other gene therapies require complex procedures, such as removal of cells from a patient and modification of those cells which are then reinfused into the patient, and many, unlike REQORSA, lead to permanent changes in a patient’s DNA. Many approved cancer therapeutics target only single molecules or a single specific genetic abnormality related to driving the proliferation and survival of cancer cells. In contrast, REQORSA has been shown to have a multimodal mechanism of action whereby it interrupts cell signaling pathways that cause replication and proliferation of cancer cells, re-establishes pathways for programmed cell death (apoptosis) in cancer cells, and modulates the immune response against cancer cells. REQORSA also has been shown to be complementary with targeted drugs and immunotherapies. Resistance to targeted drugs and checkpoint inhibitors often develops through activation of alternate bypass pathways. For example, when PD-1 is blocked, the TIM-3 checkpoint is up-regulated. We believe that REQORSA’s multimodal activity will block emerging bypass pathways, thereby potentially reducing the probability that drug resistance develops. Our preclinical and clinical data indicate that REQORSA is well tolerated and may be effective alone or in combination with targeted small molecule therapies. Preclinical data indicate that REQORSA may also be effective with immunotherapies, and in a three-drug combination with immunotherapy and chemotherapy. These data suggest that REQORSA, when combined with other therapies, may be effective in a large population of lung cancer patients. 5 TUSC2, the Tumor Suppressor Gene in REQORSA® TUSC2 is a multifunctional gene that plays a vital role in cancer suppression and normal cell regulation. Key TUSC2 anti-cancer mechanisms of action include the inactivation of multiple oncogenic kinases, the induction of apoptosis, the control of cell signaling and inflammation, and modulation of the immune system to fight cancer. REQORSA has been shown to be complementary with targeted drugs and immunotherapies. Our preclinical data indicate that REQORSA in combination with both EGFR TKIs and with immunotherapies can achieve results more favorable than results achieved with either REQORSA or such other therapies alone, and may make those drugs effective for patients with drug resistance who would not otherwise benefit from them. Normal TUSC2 function is often inactivated early in cancer development, making TUSC2 a potential target for all stages of cancer, including metastatic disease. The TUSC2 protein is reduced or absent in approximately 82% of NSCLCs and in 100% of SCLCs. In patients with NSCLC, the loss of TUSC2 expression has been associated with significantly worse overall survival than when TUSC2 expression is not decreased. Studies show TUSC2 protein functions as a key mediator in the Apaf1-mediated mitochondrial apoptosis pathway by recruiting and directing cytoplasmic Apaf1 protein to a critical cellular location and activating it in situ, thereby up-regulating activity of other proapoptotic effectors. TUSC2 functions to mediate apoptosis in cancer cells through interaction with Apaf1 and also down-regulates multiple tyrosine kinases that control cell growth, including EGFR, AKT, platelet-derived growth factor receptor (“PDGFR”), c-Kit, and c-Abl. In normal cells, the proteins involved in the PI3K/AKT/mTOR pathway play an important role in cellular function and cellular trafficking. In this pathway, PI3K, a kinase, generates messenger molecules required to translocate AKT, another protein kinase, to the cell’s plasma membrane where it is phosphorylated and activated. These proteins are often found to be aberrantly active in cancers, causing cells to lose their ability to control cell growth, proliferation, and differentiation. Thus, mutations in PI3K and its upstream activators, such as EGFR, have been associated with many forms of cancers. Similarly, proteins in the Ras/MAPK pathway, which is a signal transduction pathway that transduces signals to the cell nucleus where specific genes are activated for cell growth, division and differentiation, play a critical role in cellular responses to various stress stimuli, including osmotic stress, DNA damage, and inflammation. As shown in the figures below, the TUSC2 protein, a potent pan-kinase inhibitor, blocks multiple cell-signaling pathways downstream of the EGFR receptor and leads to cell cycle interruption, thereby preventing cancer cell proliferation and survival. Under stress conditions, such as oncogenic stress, cells go through a regulated process of programmed cell death, also known as apoptosis. As illustrated in the schematic below, the TUSC2 protein interacts via various apoptotic signaling pathways such as Apa1 to stimulate programmed cell death via the release of caspases, enzymes that play a significant role in apoptosis. 6 Pan-Kinase Inhibition by TUSC2 Stimulation of Apoptotic Signaling by TUSC2 7 Our clinical and preclinical data indicate that the combination of REQORSA with EGFR TKIs, may increase anti-tumor activity in cancers with or without EGFR mutations and in cancers that have become resistant to EGFR TKI therapy, thus potentially expanding the number of patients who could benefit from those drugs. TUSC2 and the Immune Response. In addition to its pro-apoptotic cytotoxicity and tyrosine kinase inhibitory activity, TUSC2 enhances the immune response to cancer. Data from preclinical studies at MD Anderson has shown a benefit from the combination of TUSC2 and anti-PD-1 antibody and a key role for TUSC2 in regulating immune cell subpopulations including cytokines, natural killer (“NK”) cells, and T lymphocytes. In addition, TUSC2 has been found to down-regulate PD-L1 on the surface of cancer cells. As a result, lymphocytes expressing the PD-1 receptor are more likely to recognize the cancer cell as an altered cell that should be destroyed. In addition, by inducing tumor cell apoptosis TUSC2 increases antigen release and presentation, thus promoting an enhanced antitumor response in the presence of other immune regulators. NK cells, an important part of the innate immune system, have developed several mechanisms to distinguish healthy cells from target cells. These mechanisms allow NK cells to kill cells that are deemed dangerous to the host, including cancer cells. However, one of the consequences of malignant transformation is the ability of the cancer cell to evade the immune system. Cancer cells do so via the up-regulation and interplay of receptors, including checkpoint inhibitors such as PD-1 and PD-L1. As shown in the illustration below, TUSC2 has been found to stimulate the release of interleukin-15, or IL-15, resulting in up-regulation of mature NK cells that circulate and target cancer cells. Modulation by TUSC2 of the Immune Response to Cancer In work presented in an abstract for the 2024 American Association of Cancer Research (AACR) meeting, our clinical collaborators have shown that TUSC2 has metabolic effects both in lung cancers and in normal cells. TUSC2 is encoded by the nuclear DNA, but the TUSC2 protein resides in the inner membrane of the mitochondria. TUSC2 has been shown to play a critical role in mitochondrial respiration/energy metabolism, reactive oxygen species production, and in Ca2+ flux to and from mitochondria. This recent work demonstrated that TUSC2 re-introduction to TUSC2-deficient cancer cells consistently suppressed both glycolysis and mitochondrial ATP production, thus leaving cells without sufficient energy to support their vital functions. This suggests that TUSC2 protein introduced to cancer cells lacking TUSC2 can decrease the high metabolic rate that is characteristic of cancer cells, leading to marked decreases in cell growth. The data also showed that both glycolytic and mitochondrial metabolism of a normal epithelial cell line were strengthened after the introduction of TUSC2, suggesting a beneficial role of TUSC2 for the metabolic health of normal cells. This suggests that TUSC2 effects on metabolism in normal lymphocytes could lead to the increased immune response to lung cancers seen in animal models receiving REQORSA. The study further suggested that REQORSA may play an important role as a cancer treatment to target and disrupt the metabolism of cancer cells, leading to a decrease in the rate of glycolysis. 8 ONCOPREX® Delivery System Our oncology platform consists of DNA plasmids expressing tumor suppressor genes contained in non-viral lipid-based nanoparticles in a lipoplex form (“lipoplexes”) delivered intravenously. Lipoplexes (see figure below) have lipid-based nanoparticles that clump together, thus protecting the DNA between them from being destroyed in the bloodstream. REQORSA utilizes the ONCOPREX® Delivery System to encapsulate the TUSC2 gene in positively charged lipoplexes that are attracted to negatively charged cancer cells, and then enter the cancer cell through selective endocytosis, a process by which cells take in substances from outside the cell by engulfing them in a vesicle. Operation of the ONCOPREX Delivery System The cationic (positive) charge of the lipoplexes helps to target cancer cells, which have a slight negative charge due to their high glycolytic rate. A Phase 1 clinical trial showed that intravenous REQORSA therapy selectively and preferentially targeted tumor cells, resulting in anticancer activity. The lipoplexes are non-immunogenic, allowing repetitive therapeutic dosing and providing extended half-life in the circulation. The ONCOPREX Delivery System is a non-viral delivery system. Many gene therapies rely on viral based delivery systems. The benefit of the viral system is that viruses are skilled at penetrating cells. However, viruses can also affect more than one type of cell and it is possible that the virus may infect cells other than the targeted cells containing mutated genes. If this happens, healthy cells may be damaged causing other illness or diseases, such as cancer. Once REQORSA is taken up into a cancer cell, the TUSC2 gene is expressed and TUSC2 protein is capable of restoring certain defective functions in the cancer cell. REQORSA has been designed using the ONCOPREX Delivery System to deliver the functioning TUSC2 gene to cancer cells while minimizing their uptake by normal tissue. Laboratory studies showed that the uptake of TUSC2 in tumor cells after REQORSA treatment was 10 to 33 times the uptake in normal cells, and studies in three NSCLC patients showed a major increase in TUSC2 expression in tumor tissue one day after REQORSA administration. REQORSA is also delivered systemically as opposed to many other gene therapies which are locally delivered. 9 REQORSA Origins, Development Rationale, and Strategy TUSC2 was discovered through a lung cancer research consortium from MD Anderson and The University of Texas Southwestern Medical Center along with the National Cancer Institute. The TUSC2 discovery teams included Jack A. Roth, MD, FACS, chairman of our Scientific Advisory Board. Our goal is to utilize our novel gene therapy platform to provide more effective treatments to large patient populations suffering from devastating illness. REQORSA, our lead oncology product candidate, initially is being developed as a potential treatment for NSCLC and SCLC. Clinical and preclinical data indicate that REQORSA, when combined with EGFR TKIs such as Tagrisso, Tarceva and Iressa, provides a synergistic effect. Further, our data shows that REQORSA may re-sensitize EGFR positive patients who become resistant to, and therefore no longer benefit from, EGFR TKIs alone. Preclinical and clinical data support our belief that REQORSA may provide medical benefit in several subpopulations of NSCLC patients for which there is an unmet medical need, such as NSCLC patients with EGFR mutations, and ALK positive NSCLC patients. These data also served as the basis for the receipt from the FDA in January 2020 of our first Fast Track Designation. This FDA Fast Track Designation is for use of the combination of REQORSA with Tagrisso for the treatment of NSCLC patients with EGFR mutations whose tumors progressed after treatment with Tagrisso. Preclinical data also have shown that REQORSA enhances the immune response to cancer. Data from preclinical studies at MD Anderson have shown a therapeutic benefit from the combination of TUSC2 and anti-PD-1 antibody or anti-PD-L1 antibody and a key role for TUSC2 in regulating immune cell subpopulations including cytokines, NK cells, and T lymphocytes. In addition, TUSC2 has been found to down-regulate PD-L1 on the surface of cancer cells. These data, along with our previous preclinical and clinical data, provided the basis for the receipt from the FDA in December 2021 of our second Fast Track Designation. In granting this Fast Track Designation, the FDA found that REQORSA has the potential to provide a benefit over existing therapies for patients whose tumors progress on Keytruda. This FDA Fast Track Designation is for use of the combination of REQORSA with Keytruda for the treatment of NSCLC patients whose tumors progressed after treatment with Keytruda. Our study in SCLC builds on the preclinical data showing that REQORSA enhances the immune response to cancer, and that the combination of REQORSA and immune checkpoint inhibitors demonstrates a therapeutic benefit over immune checkpoint inhibitors alone. Immune checkpoint inhibitors, such as Tecentriq, have recently been approved for use in ES-SCLC. Tecentriq, for instance, is used in combination with the chemotherapy drugs carboplatin and etoposide for 4 cycles of therapy, and then Tecentriq is administered alone as maintenance therapy until disease progression. Unfortunately, this is a relatively short time since the median PFS after starting maintenance therapy is 2.6 months. Our goal with combining REQORSA and Tecentriq as maintenance therapy is to prolong PFS and survival of ES-SCLC patients. In June 2023, the FDA granted our third Fast Track Designation. In granting this Fast Track Designation, the FDA found that REQORSA has the potential to provide a benefit over existing therapies for patients with ES-SCLC. This FDA Fast Track Designation is for the use of the combination of REQORSA with Tecentriq as maintenance therapy in patients with ES-SCLC who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. In August 2023, the FDA also granted Orphan Drug Designation to REQORSA for the treatment of SCLC. Preclinical studies by MD Anderson researchers have included combining REQORSA with: ● the EGFR TKI gefitinib (marketed as Iressa® by AstraZeneca Pharmaceuticals) in animals and in human NSCLC cells; ● third generation EGFR TKIs such as osimertinib (marketed as Tagrisso® by AstraZeneca Pharmaceuticals); ● MK2206 in animals (MK2206 is an inhibitor of AKT kinases, which affect cell signaling pathways downstream from tyrosine kinases); ● the anti-PD-1 antibody pembrolizumab (the checkpoint inhibitor marketed as Keytruda® by Merck & Co.) in animals; ● the anti-PD-1 antibody nivolumab (the checkpoint inhibitor marketed as Opdivo® by Bristol-Myers Squibb Company) in animals; and ● the anti-CTLA4 antibody ipilimumab (marketed as Yervoy® by Bristol-Myers Squibb Company) in animals. The manufacturers of the marketed drugs were not involved in any of our clinical or preclinical studies. In clinical studies involving marketed drugs, the drugs were administered concurrently with REQORSA without being modified in any way, and the antibodies used in our preclinical studies that did not use the marketed drugs were the non- humanized equivalent to marketed drugs. Data from these clinical and preclinical studies indicates that combining REQORSA with these other therapies yields results more favorable than either these therapies or REQORSA alone, with minimal side effects relative to other lung cancer drugs, thereby potentially making REQORSA a therapy complementary to these cancer treatments. 10 Acclaim-1 As described above, in January 2020, we received Fast Track Designation from the FDA for use of REQORSA in combination with TKI Tagrisso for the treatment of NSCLC patients with EGFR mutations whose tumors progressed after treatment with Tagrisso. We currently are enrolling and treating patients in the Phase 2a expansion portion of our Phase 1/2 Acclaim-1 clinical trial, an open-label, dose-escalation and clinical response study of REQORSA in combination with Tagrisso in patients with advanced, EGFR-mutant, metastatic non-small-cell lung cancer who have progressed after treatment with Tagrisso. Patients must have histologically confirmed unresectable stage III or IV EGFR-positive NSCLC (any histology) with: ● radiological progression on Tagrisso (third generation EGFR-TKI); and ● ECOG performance status of 0 to 1. We enrolled 12 patients in the completed Phase 1 dose escalation portion of the Acclaim-1 study and estimate that the Phase 2a expansion portion will enroll approximately 66 patients in 2 cohorts, and the randomized Phase 2b portion will enroll approximately 74 patients. Starting with the Phase 2a expansion portion of the study, all patients receiving REQORSA in this study are required to submit an archival biopsy specimen that can be evaluated for TUSC2 expression. Half of the patients enrolled in the Phase 2a expansion portion of the study will be patients who received only prior Tagrisso treatment and the other half will be patients who received prior Tagrisso treatment and chemotherapy. The aim is to determine toxicity and efficacy profiles of patients with different eligibility criteria. There will be an interim analysis following the treatment of 19 patients in each cohort. In connection with the Phase 2 expansion portion of the trial, we are in the process of adding approximately 3-5 additional clinical sites and we expect to enroll patients at approximately 10-15 U.S. clinical sites for the Acclaim-1 study. We opened the Phase 2a expansion portion of the Acclaim-1 study and enrolled and dosed the first patient in January 2024. We expect to complete the enrollment of the 19 patients in each cohort of the Phase 2a expansion portion of the study by the end of 2024, and thus we expect the interim analyses in early 2025. Patients enrolled in the Phase 2b portion of the study will be randomized 1:1 to either REQORSA and Tagrisso combination therapy or to platinum-based chemotherapy. Patients will be treated until disease progression or unacceptable toxicity is experienced. The primary endpoint of the Phase 1 portion of the Acclaim-1 study was to determine a dose with DLT or, if DLT was not experienced, to determine the randomized RP2D. Since no DLTs were experienced in Phase 1, the 0.12 mg/kg dose of REQORSA was determined to be the RP2D. The primary endpoint of the Phase 2a expansion portion is overall response rate (ORR). The primary endpoint of the Phase 2b randomized portion of the trial is PFS which is defined as time from randomization to disease progression) or death. Patients will be followed for survival. In October 2023, one of our clinical collaborators presented a poster presentation at the 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics detailing the Phase 1 results of the Acclaim-1 study. While the Phase 1 portion of the Acclaim-1 study was designed primarily to assess safety, we believe promising efficacy results were also observed. The reported results showed no DLTs, established a RP2D of 0.12 mg/kg (the highest dose level administered in the trial) and provided data showing early efficacy of REQORSA in combination with Tagrisso. Of the 12 patients treated with escalating doses of REQORSA and standard doses of Tagrisso, all of whom had progressed on Tagrisso containing regimens, three patients, as of data from January 2024, had experienced prolonged time to progression, including one with continuing partial response. Specifically, one patient at the 0.06 mg/kg dose level, previously treated with carboplatin, pemetrexed, and Tagrisso, had a partial remission by investigator evaluation and treatment is now ongoing in the trial after 28 cycles, which is approximately 19.5 months. A second patient at the 0.12 mg/kg dose level who was previously treated with cisplatin, pemetrexed, carboplatin, and Tagrisso has stable disease and is continuing to receive REQORSA after 14 cycles, or approximately 10 months. And a third patient who was at the 0.09 mg/kg dose level, previously treated with Tagrisso, had stable disease and received 14 cycles, over approximately 10 months before disease progression occurred. The extended PFS of each of these patients is consistent with long-term PFS seen in several patients in prior early stage clinical trials of REQORSA and is not expected with treatment with Tagrisso alone after progression on Tagrisso. REQORSA administration was generally well tolerated and there were no DLTs. The administration was associated with a delayed infusion-related reaction of muscle aches, fever and chills in some patients, which we believe is similar to reactions seen with the administration of antibodies routinely used in oncology treatment. This was managed with prophylactic steroids, acetaminophen and diphenhydramine, and symptoms decreased with repeat cycles. We believe this new mechanism and novel approach targeting lung cancer, which comes with a strong safety profile and early signs of efficacy, is paving new ground in the fight against lung cancer. 11 Acclaim-2 In December 2021, we received Fast Track Designation from the FDA for use of REQORSA in combination with the checkpoint inhibitor Keytruda for the treatment of advanced NSCLC patients whose tumors progressed after treatment with Keytruda. In 2019, preclinical data were presented by MD Anderson collaborators relating to the combination of REQORSA, with Keytruda showing that TUSC2 combined with the checkpoint blockade mechanism of action of Keytruda was more effective than Keytruda alone in increasing the survival of mice with a human immune system (humanized mice) that had metastatic lung cancer with a human lung cancer. MD Anderson also presented preclinical data in 2019 for the combination of TUSC2, Keytruda and chemotherapy for the treatment of some of the most resistant metastatic lung cancers. This study found that the addition of TUSC2 demonstrates synergy with Keytruda and also with Keytruda combined with chemotherapy, and thus, may improve on the first-line standard of care for lung cancer which includes chemotherapy. We currently are enrolling and treating patients in the Phase 1 dose escalation portion of our Phase 1/2 Acclaim-2 clinical trial, an open-label, dose-escalation and clinical response study of REQORSA in combination with Keytruda in patients with advanced, metastatic non-small-cell lung cancer who have progressed after treatment with Keytruda. Patients must have histologically confirmed unresectable stage III or IV NSCLC (any histology) with: ● radiological progression on Keytruda; and ● an ECOG performance status of 0 to 1. Starting in 2024, all patients receiving REQORSA in this study are required to submit an archival biopsy specimen that can be evaluated for TUSC2 expression. We expect to enroll patients at approximately 10 U.S. clinical sites and estimate that the dose escalation portion of the Acclaim-2 trial will enroll up to 18 patients, the Phase 2a expansion portion will enroll 36 patients, and the Phase 2b randomized portion will enroll approximately 126 patients. Patients enrolled in the Phase 2b randomized portion of the study will be randomized 2:1 to either REQORSA and Keytruda combination therapy in the experimental arm or to chemotherapy (docetaxel with or without ramucirumab), or to the investigator’s choice of therapy in the control arm. Patients will be treated until disease progression or unacceptable toxicity is experienced. The primary endpoint of the dose escalation portion is DLT, defined as ≥Grade 3 prolonged non-hematological or ≥Grade 4 prolonged hematological toxicity occurring during the first cycle of therapy and considered to be possibly, probably, or definitely related to REQORSA and Keytruda combination therapy. The primary endpoint of the Phase 2a expansion portion and the Phase 2b randomized portion of the trial is progression-free survival which is defined as time from randomization to disease progression or death. Patients will be followed for survival. Patients are currently being treated at the 0.06 mg/kg dose level and, subject to Acclaim-2 SRC approval, we will treat the two successive cohorts of patients at the 0.09 mg/kg and 0.12 mg/kg dose levels. In March 2023, we amended the Acclaim-2 protocol to include additional treatments in the control group with the goal of accelerating enrollment in the study by making the trial more attractive to a wider variety of investigators. We expect enrollment in the Phase 1 dose escalation portion of the Acclaim-2 trial will be completed in the second half of 2024. We will then initiate and evaluate patients in the Phase 2a expansion portion of the study at the MTD or RP2D to expand the safety and efficacy profile at that dose in order to better evaluate efficacy and to increase the likelihood of a successful Phase 2b randomized trial, which will follow the expansion portion. 12 Acclaim-3 In June 2023, the FDA granted Fast Track Designation for the Acclaim-3 treatment combination of REQORSA and Tecentriq as maintenance therapy in patients with ES- SCLC who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. In August 2023, the FDA granted Orphan Drug Designation to REQORSA for the treatment of SCLC. We currently are enrolling patients in the Phase 1 dose escalation portion of our Phase 1/2 Acclaim-3 clinical trial. Patients in the study will be enrolled after receiving initial treatment with 3-4 cycles of carboplatin, etoposide, and Tecentriq, and achieving complete response, partial response or stable disease. They will then receive treatment with REQORSA and Tecentriq as maintenance therapy every 21 days until disease progression. In January 2024, we opened the Phase 1 portion of the Acclaim-3 study for enrollment and added multiple clinical sites through our collaboration with a large network of integrated, community-based oncology practices. We now anticipate enrolling patients at approximately 10 U.S. clinical sites and estimate that the Phase 1 dose escalation portion of the Acclaim-3 trial will enroll up to 12 patients, and the Phase 2 expansion portion will enroll approximately 50 patients at approximately 10 to 15 U.S clinical sites. Patients will be treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. The primary endpoint of the Phase 1 escalation portion is to determine the MTD or RP2D and the primary endpoint of the Phase 2 portion is to determine the 18-week progression-free survival rate from the time of the start of maintenance therapy with REQORSA and Tecentriq in patients with ES-SCLC. Patients will also be followed for survival. We expect to complete the Phase 1 portion of the study during the second half of 2024 and we expect to start the Phase 2 expansion portion of our Acclaim-3 study in the second half of 2024. 13 ONC-001: REQORSA® Phase 1 Monotherapy Trial (completed) In 2012, MD Anderson researchers completed a Phase 1 clinical trial of REQORSA as a monotherapy (the “Phase 1 Monotherapy Trial”) in patients with advanced NSCLC with disease progression at study entry. The primary objective of the REQORSA Monotherapy Trial was to assess the toxicity of REQORSA administered intravenously and to determine the MTD and RP2D of REQORSA alone. Secondary objectives were to assess the expression of TUSC2 following intravenous delivery of REQORSA in tumor biopsies and also to assess the anticancer activity of REQORSA. This trial showed that REQORSA was well tolerated and established the single-agent MTD and the therapeutic dosage for REQORSA at 0.06 mg/kg administered every 21 days. This MTD was established based on the occurrence of an asymptomatic, Grade 3 laboratory abnormality in 2 patients. Although this trial was not designed to show changes in outcomes, a halt in cancer growth was observed in a number of patients, and tumor regressions occurred in primary lung tumors and metastatic cancers in the liver, pancreas, and lymph nodes. In addition, pre- and post-treatment patient biopsies demonstrated that intravenous REQORSA selectively and preferentially targeted patient’s cancer cells and suggested that clinical anti-cancer activity was mediated by increased expression of TUSC2 in the cancer cells. In the Phase 1 Monotherapy Trial, REQORSA was injected intravenously in stage IV (metastatic) lung cancer patients who had received traditional platinum combination chemotherapy but had tumor progression at the time of entry into the study. Thirty-one subjects were treated at six dose levels. Seventy percent of subjects had received two or more prior chemotherapy regimens. The only serious adverse events were grade 3 fever (experienced by three patients) and grade 3 hypotension (experienced by 1 patient). The only dose- limiting toxicities were two episodes of transient grade 3 hypophosphatemia (abnormally low levels of phosphate in the blood) resulting in an MTD of 0.06 mg/kg. Five patients, or 22% of the 23 evaluable patients, achieved disease control for periods ranging from 2.6 months to 10.8 months. The median disease control period for these patients was 5.0 months (95% CI: 2.0-7.6). Median survival for all subjects in the Phase 1 Monotherapy Trial was 8.3 months (95% CI 6.0-10.5 months) and mean survival time was 13.2 months (95%CI 8.9-7.5 months) with a range of two to 23+ months. Two subjects had reductions in primary tumor size of 14% and 26%. One subject with stable disease, a 54-year-old female with a large cell neuroendocrine carcinoma who received 12 cycles of REQORSA therapy before having disease progression, had evidence of a durable metabolic response, which is a lasting reduction of metabolic activity in the tumor, as shown by positron emission tomography ("PET") imaging. The response was documented with PET scans performed after the second, fourth and sixth doses, all showing markedly decreased metabolic activity in the tumor with no changes in size or number of metastases by computed tomography ("CT") imaging. The illustration below is of the PET scan of this subject performed at baseline (Illustration A) and after the fourth dose (Illustration B). This subject had received six prior chemotherapy regimens. Prior to entry in the Phase 1 Monotherapy Trial, two hepatic metastases were progressing on gemcitabine. The subject also had a metastasis in the head of the pancreas and a peripancreatic lymph node, shown by the arrows in the illustration below. Illustration A shows the pretreatment PET scan. Illustration B shows the post treatment PET scan performed 20 days following the fourth dose of REQORSA. All scans were performed within a 60 to 90 minute window after injection. This subject survived after subsequent therapy more than seven years after the final treatment with REQORSA, to our knowledge, without evidence of cancer progression in the responding sites. Metabolic Tumor Response in a Metastatic Lung Cancer Subject 14 ONC-002: Phase 1/2 - Trial Combining REQORSA with Tarceva (Phase 1 portion completed; Phase 2 portion closed in order to conduct Acclaim-1 instead) Phase 1 Portion: The Phase 1 Monotherapy Trial showed that REQORSA is well tolerated, that high levels of TUSC2 expression are detected in the tumor post-treatment, and that there was evidence of tumor growth suppression. Based on the results from the Phase 1 Monotherapy Trial and substantial preclinical evidence that REQORSA is complementary with EGFR TKIs, we began a Phase 1/2 trial (the “Phase 1/2 Combination Tarceva Trial”) at MD Anderson combining REQORSA with Tarceva in patients with Stage IV (metastatic) or recurrent NSCLC that is not potentially curable by radiotherapy or surgery. Patients were enrolled whether or not they had an activating EGFR mutation. Enrollment in the Phase 1 portion of the Phase 1/2 Combination Tarceva Trial commenced in 2014 at MD Anderson with Dr. Charles Lu as the Principal Investigator. In the Phase 1 portion of the Phase 1/2 Combination Tarceva Trial, 18 subjects were treated with the following dose levels: Dose Level 1 2 3 4 Drug Doses Tarceva (100 mg/day) + REQORSA (0.045 mg/kg) Tarceva (100 mg/day) + REQORSA (0.060 mg/kg) Tarceva (150 mg/day) + REQORSA (0.045 mg/kg) Tarceva (150 mg/day) + REQORSA (0.060 mg/kg) As in the Phase 1 Monotherapy Trial, subjects received a pre-treatment regimen of oral and intravenous dexamethasone and diphenhydramine to prevent infusion reaction symptoms such as fever, along with an infusion of REQORSA every three weeks. Subjects received oral Tarceva daily during each three-week cycle during the treatment period. The Phase 1 portion of the Phase 1/2 Combination Tarceva Trial was also a dose escalation study with the primary purpose of determining the MTD. DLT were defined as grade 3, 4, or 5 events during the first cycle of treatment that were considered to be treatment related. At dose level 1, one subject had grade 3 adverse events of fatigue, muscle weakness, and hyponatremia (low sodium level) considered to be related to the study treatment (Tarceva). Therefore, three additional subjects were treated at this dose level (six subjects total), none of whom had a DLT. At dose level 2, there were no DLTs. At dose level 3, one subject had a grade 3 rash considered to be related to the study treatment (Tarceva); therefore, an additional three subjects were treated at this dose level (six subjects total). No additional subjects had a DLT. At dose level 4, there were no DLTs; thus, dose level 4, as the highest dose evaluated, was determined to be the dose to be used in the Phase 2 portion of the study. Since the eligibility criteria, drug administration details (other than dose) and evaluation details were identical for the Phase 1 portion and the Phase 2 portion, the three subjects in the Phase 1 portion of the Phase 1/2 Combination Tarceva Trial who were treated at the Phase 2 dose (0.06 mg/kg) were included in the analysis of the Phase 2 portion of the study. Phase 2 Portion: The Phase 2 portion of the Phase 1/2 Combination Tarceva Trial was a Simon two-stage trial designed to include subjects treated with the combination of REQORSA and Tarceva at the Phase 2 dose with the primary goal of measuring the response rate, and secondary endpoints of stable disease, time to progression and overall survival. The response rate for cancer therapies was defined as Complete Response (CR) + Partial Response (PR); disease control rate was defined as Complete Response (CR) + Partial Response (PR) + Stable Disease (SD) > 8 weeks. Although this Simon two-stage trial was closed early to start the Acclaim-1 study instead, the trial had already met the required response rate to advance to the second stage and to complete the full enrollment. Enrollment criteria for the Phase 2 portion were identical to those in the Phase 1 portion. Subjects received three-week cycles of REQORSA in combination with Tarceva until the occurrence of progressive disease (PD), unacceptable toxicity, withdrawal of consent, or study treatment discontinuation for other reasons, whichever occurred first. Of the 39 patients planned for the Phase 2 portion of the trial, 10 were enrolled (three of whom were also subjects of the Phase 1 portion of the Phase 1/2 Combination Tarceva Trial). None of the 10 subjects treated in the Phase 2 portion of the Phase 1/2 Combination Tarceva Trial had a DLT. Results from the Phase 2 portion for the 10 patients show that: ● One patient had a response of CR for a study CR rate of 10% and the overall response rate (CR + PR) was also 10%; ● Three patients had tumor regression; and ● Disease control rate was 70%. 15 The patient with the CR, a 58-year-old female, upon enrollment in the study had metastatic NSCLC following 6 cycles of pemetrexed and carboplatin and after two cycles of maintenance pemetrexed had cancer progression. The patient’s tumor had EGFR exon 18 and 20 missense mutations, which are not sensitive to Tarceva alone. This patient had disappearance of lung lymph node metastases. The response rate and disease control rate observed in the Phase 2 portion of the Phase 1/2 Combination Tarceva Trial substantially exceeds the response rate of 7% (with no CRs) and disease control rate of 58% reported for a clinical trial of the EGFR TKI afatinib (marketed as Gilotrif® by Boehringer Ingelheim Pharmaceuticals, Inc.) in a study referred to as the LUX-Lung 1 clinical trial. The LUX-Lung 1 clinical trial was a randomized, double blinded Phase 2b/3 clinical trial treating subjects with Stage IIIB or IV adenocarcinoma, a type of NSCLC. Patients in that trial had received one or two previous chemotherapy regimens and had disease progression after at least 12 weeks of treatment with EGFR inhibitors erlotinib or gefitinib. A total of 585 patients were enrolled in that Phase 2b/3 clinical trial, whose primary endpoint was overall survival and whose secondary endpoints included progression-free survival and RECIST response. The Phase 2 portion of our Phase 1/2 trial was not blinded and was designed to treat NSCLC subjects regardless of EGFR status. The following table provides data from the Phase 2 portion of the Phase 1/2 Combination Tarceva Trial for subjects with and without EGFR mutations. Note that two patients with disease progression on Tarceva received 10 and 12 cycles of Tarceva, respectively, before disease progression and entry into the trial. With the combination of REQORSA and Tarceva, both of these patients had stable disease, suggesting that the combination therapy may be an effective treatment for patients whose disease is progressing after extensive Tarceva treatment. We are no longer enrolling the Phase 2 portion of the Phase 1/2 Combination Tarceva Trial in favor of conducting the Acclaim-1 trial, which combines REQORSA with Tagrisso, since Tagrisso has been shown to be more effective than Tarceva as initial therapy for patients with NSCLC with EGFR mutations. 16 Preclinical Studies of REQORSA Supporting Our Conduct of Acclaim-1 REQORSA and Tyrosine Kinases. Investigators at MD Anderson conducted preclinical research showing that REQORSA alone blocked the activation of the c-Abl tyrosine kinase. A number of other studies at MD Anderson have shown the complementary effects of REQORSA combined with a variety of targeted kinase inhibitory agents, both marketed and in various stages of clinical development, including Tarceva, Iressa, and Tagrisso. REQORSA and TUSC2 deficient and Tarceva or Iressa resistant cell lines. MD Anderson researchers also tested REQORSA in TUSC2-deficient and Tarceva- or Iressa- resistant NSCLC cell lines. Treatment of the NSCLC EGFR mutation negative cell lines H1299, H322, H358 and H460 cancer cell line showed that the REQORSA combination significantly sensitized (p<0.001) response of the cancer cell lines to both Tarceva or Iressa treatment and synergistically induced apoptosis in vitro. The findings were confirmed in vivo in an H322 orthotopic lung cancer mouse model. These studies included the Kras mutant cell line H460, which is significant because patients with Kras mutant tumors are generally unresponsive to Tarceva or Iressa. Synergistic induction of apoptosis was observed with the combination of REQORSA and concentrations of Tarceva or Iressa similar to steady-state serum concentrations achievable with oral dosing. The combination of REQORSA and either Tarceva or Iressa induced similar levels of tumor cell growth inhibition, apoptosis induction, and inactivation of oncogenic protein kinases. Data from these and other studies suggest a combination of REQORSA with Iressa or Tarceva can promote synergistic tumor cell killing and overcome drug-induced resistance by simultaneously inactivating the EGFR and the AKT signaling pathways and by inducing apoptosis in resistant cells with nonmutated EGFR. These data suggest that NSCLC patients with an activating EGFR mutation, whose cancer progresses on Tarceva, may potentially benefit from REQORSA with Tarceva combination therapy. These data also suggest that NSCLC patients without an activating EGFR mutation (generally unresponsive to Tarceva) may potentially benefit from REQORSA with Tarceva combination therapy. These data provided strong support for the ONC-002 trial, which combined REQORSA with Tarceva. REQORSA in Tagrisso resistant cell lines. Tagrisso (osimertinib), a third-generation EGFR inhibitor, shows robust clinical activity, yet patients inevitably develop secondary resistance. An osimertinib resistant H1975-OsiR isogenic cell line was developed through continuous exposure to osimertinib, and an osimertinib resistant clone was selected which showed 100-fold higher resistance to osimertinib compared with its parental counterpart (H1975-parental). Xenograft tumors from both H1975-parental and H1975- OsiR cells were developed in NSG mice and were treated with osimertinib. H1975-OsiR tumors were significantly less sensitive than its parental counterpart. Synergistic antitumor activity of TUSC2+osimertinib was found in H1975-OsiR tumors where both TUSC2+osimertinib (5mg/kg) and TUSC2+osimertinib (10mg/kg) combinations showed a robust antitumor effect compared with single agent treatment groups. No synergistic effect was observed for H1975-parental tumors. In conclusion, TUSC2 therapy in combination with osimertinib showed synergistic antitumor efficacy in EGFR mutant osimertinib resistant NSCLC tumors. These data provide a strong biologic rationale for the Acclaim-1 clinical trial. Preclinical Studies of TUSC2 in the Immune Response to Cancer Supporting Our Conduct of Acclaim-2 Preclinical studies indicate that REQORSA is selectively taken up by tumor cells with a 10 to 33 fold differential favoring uptake by tumor cells, thus imparting a passive targeting property without the need to attach targeting ligands. REQORSA targeting is partly due to the attraction of opposite charges (REQORSA has a positive charge, normal cells no charge, and most cancer cells have a negative charge), and partly due to enhanced endocytosis by tumor cells, and is enhanced by the leakiness that is characteristic of tumor vasculature. In experimental mouse xenograft models, the ONCOPREX delivery system was shown to efficiently deliver several therapeutic tumor suppressor genes (TP53, FHIT, TUSC2) to disseminated human cancer cells. Metastatic tumor growth was suppressed, and survival prolonged, after systemic administration of the genes via a nanovesicle vector. Human NSCLC A549 cells have virtually no TUSC2 protein. As shown in Figure 1, intratumoral administration of REQORSA (referred to as FUS1 in Figure 1) to subcutaneous NSCLC H1299 tumor xenografts resulted in inhibition of tumor growth. 17 Figure 1. Effect of REQORSA on the Growth of H1299 Subcutaneous Tumor Xenografts in Nude Mice Moreover, intravenous injections of REQORSA into mice bearing experimental A549 lung metastases resulted in a decrease in the number of metastatic tumor nodules. Lung tumor-bearing animals treated with REQORSA also had a significant increase (P=0.01) in survival time (median survival time: 80 days) compared with 48 to 51 days for control animals. Analysis of TUSC2 expression by IHC following REQORSA treatment showed distribution of TUSC2 throughout the tumor in a high percentage of the tumor cells. These results demonstrate the potent tumor suppressing activity of the TUSC2 gene, supporting the feasibility of using nanovesicles for systemic plasmid delivery to metastases as well as to primary tumors, and implicating REQORSA as a promising therapeutic agent for primary and disseminated human lung cancer. 18 REQORSA Synergizes with Pembrolizumab It was previously shown that the combination of REQORSA and an anti-PD1 antibody inhibited tumor growth synergistically in subcutaneous and metastatic NSCLC KRAS mutant syngeneic mouse models. To determine whether this synergy also applies to the KRAS/LKB1 mutant subtype of human A549 NSCLC cells, humanized mice harboring KRAS/LKB1 mutant A549 lung metastases were treated with REQORSA, pembrolizumab or the combination. These studies were performed with an improved humanized mouse model using fresh human umbilical cord blood derived CD34+ stem cells in irradiated NSG mice, in which mouse immune system cells have been largely destroyed. The reconstituted humanized mice have a fully competent human immune system with major functional immune populations and were used here to evaluate synergy between REQORSA and pembrolizumab. The treatment strategy is shown in Figure 2A. REQORSA (referred to as TUSC2 in Figure 2) was administered intravenously every 48 hours for a total of three injections, and pembrolizumab was administered every 3-4 days a total of three times. Bioluminescence imaging was performed to visualize the intensity of tumor burden for mice in different treatment groups both in humanized and non-humanized mice. Both REQORSA and pembrolizumab monotherapies reduced the tumor burden significantly, although pembrolizumab was moderately more effective. Importantly, REQORSA plus pembrolizumab inhibited tumor growth synergistically (*P< 0.05, **P< 0.005, ***, P< 0.0005). (Figure 2B, C). There was no antitumor effect of pembrolizumab and reduced change with REQORSA in non-humanized mice, which was expected since these mice have no immune cells. To identify the immunological features associated with efficacy of this combination, in depth immune profiling of the tumor microenvironment was performed. An increased number of reconstituted human CD3+ T cells was found in all groups, compared with the untreated control. CD8+ T cells were significantly upregulated by pembrolizumab and its combination with REQORSA (Figure 2D). Levels of activated CD8+ T cells (CD8+CD69+) were also significantly increased in the combination group and were slightly higher than the pembrolizumab group (Figure 2D). There was no effect of pembrolizumab on NK/activated NK cells, whereas REQORSA alone enhanced their levels significantly, indicating REQORSA regulation of NK activation, which is consistent with the previous findings reported in syngeneic mice. The combination had a similar effect as REQORSA monotherapy (Figure 2E). REQORSA, pembrolizumab, and the combination, were all associated with significant decrease of reconstituted human myeloid derived suppressor cells (“MDSCs”) (CD33+ve), (Figure 2F). Pembrolizumab and the combination had a profound stimulatory effect on HLA-DR+ dendritic cells (DCs), (Figure 2G). REQORSA alone enhanced HLA- DR+DC levels moderately. Taken together, these results show that the combination of REQORSA and pembrolizumab enhanced the immune response and inhibited tumor growth synergistically (*P< 0.05, **P< 0.005, ***, P< 0.0005). REQORSA also showed synergistic antitumor activity with nivolumab in the same mouse model, highlighting the role of REQORSA rendering KRAS/LKB1 mutant tumors more sensitive to immune checkpoint blockade. Thus, these data suggest that the synergy of REQORSA with immune checkpoint inhibitors is not limited to pembrolizumab. 19 Figure 2. Synergistic Antitumor Effect of REQORSA Immunogene Therapy with Pembrolizumab on KRAS/LKB1 Mutant Lung Metastases in the Humanized Mouse Model 20 Preclinical Studies of TUSC2 Supporting Our Conduct of Acclaim-3 Transfection of SCLC cells in vitro with TUSC2 showed growth inhibition and a marked suppression of colony formation compared to cells transfected with a control vector. These results demonstrate the potential tumor suppression function of TUSC2 in SCLC cells and suggest that TUSC2-mediated gene therapy could be a useful therapeutic strategy for the treatment of SCLC. Data presented at the October 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics from studies in humanized mouse models of SCLC that use human H841 cells have shown that the combination of quaratusugene ozeplasmid and atezolizumab provides significantly better control of tumor burden than either agent alone (Figure 3, Figure 4, and Figure 5). H841 is a human SCLC cell line that does not express TUSC2 protein, and which was labeled with luciferase for these experiments. When injected intravenously, H841 cells metastasize to both lung and liver. The reconstituted humanized mice have a fully competent human immune system with major functional immune populations, which showed antigen specific T cell responses as well as antitumor activity with immune checkpoint blockade therapy and was used here to evaluate synergy between quaratusugene ozeplasmid and atezolizumab. In these studies, one million H841 cells/mouse were injected intravenously, and treatment began 12 days later, after the metastases were well established. Quaratusugene ozeplasmid was administered intravenously every other weekday at a dose of 25 μg/mouse of plasmid DNA: 10 nmol liposome solution in 100 μL of D5W for 5 doses. Atezolizumab was administered at a dose of 300 μg/mouse intraperitoneal injection twice a week for 4 doses. Three weeks later, bioluminescence imaging was performed to visualize the intensity of tumor burden for mice in different treatment groups. Humanized mice with H841 xenografts were treated with quaratusugene ozeplasmid, atezolizumab or the combination. With the combination of quaratusugene ozeplasmid and atezolizumab there was a highly significant reduction in tumor burden compared to the results with atezolizumab alone (p=0.002). There was approximately a 10-fold reduction in tumor burden in the quaratusugene ozeplasmid plus atezolizumab group compared to untreated control mice. Note that 3 out of 5 mice in the quaratusugene ozeplasmid plus atezolizumab group had complete or near-complete responses (Figure 3). Figure 4 provides a graph of the bioluminescence flux in the treatment groups. Analysis of the tumor immune microenvironment in the H841 xenografts (Figure 5) shows that, compared to treatment with atezolizumab alone, the combination of quaratusugene ozeplasmid and atezolizumab leads to increased numbers of huCD8 T-cells, NK cells, and DC, and lower numbers of MDSCs. These changes indicate an increased immune response to the xenograft and identify at least one mechanism responsible for the increased tumor response seen with quaratusugene ozeplasmid and atezolizumab in combination. In summary, the data from these studies suggest that a combination treatment of quaratusugene ozeplasmid and atezolizumab can promote a significantly increased tumor cell killing effect in SCLC xenografts compared to that of atezolizumab alone.

Diabetes mellitus refers to a group of metabolic diseases that affect how the body produces and uses blood sugar (glucose). Glucose is vital to health because it is an important source of energy for the cells that make up the body’s muscles and tissues. It is also the brain’s main source of fuel. Chronic diabetes conditions include Type 1 diabetes and Type 2 diabetes, both of which lead to excess glucose in the blood and can cause serious health problems. Left untreated, high blood glucose levels can damage the eyes, kidneys, nerves, and the heart, and can also lead to coma and death. Epidemiology of Diabetes. According to the U.S. Center for Disease Control as of 2023, 38.4 million Americans, or approximately 11.6% of the U.S. population, have diabetes. It is also believed that more than 97 million Americans aged 18 years or older have prediabetes. In 2021, approximately 537 million adults (20-79 years) worldwide were living with diabetes, and the total number of people living with diabetes is projected to rise to 643 million by 2030 and 783 million in 2045. Also in 2021, diabetes caused more than 6.7 million deaths globally and diabetes resulted in approximately $966 billion dollars in health expenditures, a 316% increase over the preceding fifteen years. The Role of Alpha Cells and Beta Cells. The two most abundant endocrine cell types in the pancreas, the beta and the alpha cells, are essential for the maintenance of blood glucose homeostasis whereby levels of glucose are maintained by the body within a narrow range. While the beta cell produces insulin, the only blood glucose-lowering hormone of the body, the alpha cell releases glucagon, which elevates blood glucose. 21 In people with Type 1 diabetes, however, beta cells are destroyed by the immune system and no longer secrete insulin, leading to an absolute deficit of insulin. Type 2 diabetes is due to “insulin resistance,” an initial resistance of the body’s cells to obey the direction from insulin. To overcome this resistance, the beta cells secrete more insulin, and glucose is eventually forced into the cells. Glucose is maintained within normal limits, but at the expense of increased insulin secretion by the beta cells. After many years of such increased secretion, the beta cells become “tired” from working overtime, and the fatigue process begins. This fatigue tends to be progressive, and in time the compensation for insulin resistance disappears. At that point, blood glucose levels start going up. Current Treatments for Diabetes. Advances in new treatments have helped many people better manage the disease. However, despite patients’ best attempts, managing diabetes remains a challenging, daily balancing act because exogenous insulin therapy simply cannot ideally mimic the body’s biological function. Type 1 diabetes patients are treated with insulin, with most of the progress in therapy relating to enhanced delivery of the drug and improved methods for measuring blood glucose levels. A variety of drug release technologies have allowed for rapid-acting, intermediate-acting and long-acting insulin injections that provide drug anywhere from one to 24 hours. In addition, improvements in needles, continuous delivery ports, and inhalation technologies all have helped patients better manage their disease and may impact quality of life, but none of these advances are disease modifying. Type 2 diabetes patients are advised to use diet and exercise to manage their condition. When these lifestyle changes alone do not control the disease, Type 2 diabetes patients may be prescribed a variety of medications that help alter how the body manages blood sugar levels. For example, biguanides such as metformin, reduce the amount of glucose produced in the liver. DPP-4 inhibitors, such as Januvia®, Onglyza®, and Tradjenta®, improve blood sugar levels and prevent them from dropping too low. Glucagon-like peptides, such as Byetta®, Trulicity® and Victoza®, change the way the body produces insulin. Drugs in the SGLT2 inhibitor class, such as Farxiga and Invokana, release more glucose into the urine. Finally, insulin injections may be needed if these oral medications, along with diet and exercise, do not lower blood sugar levels enough. These medications, including insulin replacement therapy, while offering improvements for Type 2 diabetes patients, do not affect the underlying cause of the disease. GPX-002 As further described in the “Licenses and Research Collaborations” section below, we have exclusively licensed from the University of Pittsburgh multiple technologies relating to the development of a gene therapy product for each of Type 1 and Type 2 diabetes. The same general novel approach is used in each of Type 1 and Type 2 diabetes whereby an AAV vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. In humans, we believe this can be done with a routine endoscopy procedure, called endoscopic retrograde cholangiopancreatography (ERCP). Our diabetes product candidates are currently being evaluated and optimized in preclinical studies at the University of Pittsburgh. GPX-002 is being developed using the same construct for the treatment of both Type 1 diabetes and Type 2 diabetes. GPX-002 for Type 1 diabetes is designed to work by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In a similar approach, GPX-002 for Type 2 diabetes (formerly known as GPX-003), where autoimmunity is not at play, is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin. We finalized the components of the diabetes construct to take forward for nonclinical studies and in December 2023, we submitted a request to meet with the FDA to obtain their guidance on the nonclinical studies needed to file an IND application and initiate first-in-human studies. As a result of the FDA’s response, the Company will continue with its planned additional nonclinical studies before requesting regulatory guidance in 2024 for the IND-enabling studies. In October 2023, we entered into a one-year extension to our August 2022 sponsored research agreement with the University of Pittsburgh for the use of GPX-002 in a NHP model in Type 2 diabetes. The extension includes a revised research plan to encompass our most recent technologies to which we acquired exclusive rights from the University of Pittsburgh in July 2023. These include a MafB promoter to drive expression of the Pdx1 and MafA transcription factors that can potentially be used for both Type 1 and Type 2 diabetes. This gene therapy approach has been tested in vivo in mice and NHPs using an earlier construct as described below. 22 Preclinical Mouse Studies In studies in mice treated to destroy insulin producing beta cells and in non-obese diabetic (“NOD”) mice, both of which are models of Type 1 diabetes, our gene therapy approach restored normal blood glucose levels for an extended period of time, and markedly increased the mass of insulin producing beta cells. The figures below show that starting approximately a week after injection of the engineered AAV construct (labeled AAV8-PM) into the pancreatic duct, the blood glucose level markedly improved in mice in which insulin producing cells had been destroyed by the drug alloxan (ALX). In addition, the mass of beta cells and beta-like cells producing insulin was significantly increased. NOD mice develop diabetes due to an immune attack that destroys the insulin producing beta cells in the pancreas. The figures below show that starting approximately a week after injection of the engineered AAV construct (labeled AAV8-PM) into the pancreatic duct the blood glucose level markedly improved in NOD mice. In addition, there is a significant increase in the mass of beta cells and beta-like cells that produce insulin. The improvement in glucose level normalization lasted approximately 4 months, which, according to the researchers could potentially translate to decades in humans. 23 The researchers also carried out an experiment to determine if the same AAV engineered construct could be used to convert human alpha cells to beta-like cells that would produce insulin as shown in the figures below. Human pancreatic islets were treated with streptozotocin (STZ) to destroy beta cells, and then were treated with the AAV engineered construct. They were then transplanted into NOD mice that had been treated with alloxan (ALX), and also modified so they would not reject human cells. The NOD mice that received the AAV engineered construct had significantly lower blood glucose levels and higher mass of beta and beta-like cells that secrete insulin than did control mice. These data suggest that the same AAV engineered construct can convert human alpha cells into insulin secreting beta-like cells. Preclinical Non-Human Primate Studies In February 2023, the Company’s research collaborators at the University of Pittsburgh presented preclinical data in a NHP model of Type 1 diabetes highlighting the therapeutic potential of GPX-002 at the 16th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD 2023) in Berlin, Germany. The statistically significant study results showed that after infusion of the AAV engineered construct all eight of the NHPs had: ● Decreased insulin requirements (p<0.001); ● Increased c-peptide levels (p<0.05); ● Improved glucose tolerance compared to baseline (p<0.05) with one demonstrating reestablished normoglycemia; and ● Insulin and glucagon staining in the same cells, suggesting the formation of insulin-producing cells. We believe these data in NHPs demonstrate the potential for this gene therapy treatment to eliminate the need for insulin replacement therapy for Type 1 and Type 2 diabetic patients. In October 2023, we entered into a one-year extension to our August 2022 sponsored research agreement with the University of Pittsburgh for the use of GPX-002 in a NHP model of Type 2 diabetes. The extension includes a revised research plan to encompass our most recent technologies to which we acquired exclusive rights from the University of Pittsburgh in July 2023. 24 Discovery Programs Oncology ONCOPREX® Delivery System as a platform. We believe that the ONCOPREX Delivery System may be applicable to delivery of a range of therapeutic and prophylactic plasmid DNA and RNA interference constructs and shows efficacy in cancers beyond lung cancer. We also believe that the manufacturing methods we have developed for REQORSA may be useful for a wide array of disease treatments. Clinical data from the use of REQORSA has shown that the ONCOPREX Delivery System is well tolerated in humans and can be delivered at high therapeutic doses. Rights to other Tumor Suppressor Genes. We have licensed rights to the tumor suppressor gene, TUSC2, which is located in a sub-region of human Chromosome 3 known as 3p21.3, on which multiple tumor suppressor genes are located, including for example, 101F6, NPRL2, CACNA2D2, PL6, BLU, RASSF1, HYAL 1 and HYAL2. Using a number of techniques, MD Anderson researchers and their collaborators have identified these genes as potentially having cancer-fighting characteristics. MD Anderson researchers have subsequently conducted a number of preclinical studies on certain of these genes, particularly NPRL2, as well as TUSC2, both alone and in combination with other compounds, in order to assess their actual effects on lung cancer. Under past and current sponsored research agreements with MD Anderson, we support continuing research into the cancer-fighting properties of these and other genes in the 3p21.3 sub-region. Researchers at MD Anderson have collaborated with other researchers to identify other genes, such as those in the 3p21.3 chromosomal region, which may act as tumor suppressors or have other cancer fighting functions. We hold rights to certain of these genes under license agreements with MD Anderson. Data from preclinical studies performed by MD Anderson researchers and others suggest that TUSC2, the active agent in REQORSA, could be effective against other types of cancer, including glioblastoma, head and neck, breast (including triple-negative breast cancer), renal cell (kidney), thyroid, and soft tissue sarcoma, as well as NSCLC and SCLC. Therefore, the ONCOPREX Delivery System may allow delivery of a number of cancer fighting genes, alone or in combination with other cancer therapies, to combat multiple types of cancer. In addition, we have identified internally other tumor suppressor genes on which we have filed for intellectual property protection. NPRL2, a tumor suppressor gene, is often reduced in NSCLC. The restoration of NPRL2 activates cell cycle arrest and apoptosis. Genprex research collaborators will present at t he 2024 AACR meeting on additional research findings supporting NPRL2, the second tumor suppressor gene enabled by the ONCOPREX Delivery System. Our researchers investigated the anti-tumor immune responses to NPRL2 gene therapy in NSCLC cells with KRAS/STK11 co-mutations. The KRAS/STK11 co-mutation is associated with resistance to PD-1/PD-L1 inhibitors, such as Keytruda, and with poor overall survival in NSCLC patients. In the study, induced lung metastases in humanized mice were treated through intravenous injection of NPRL2 nanoparticles, made with the ONCOPREX Delivery System, with or without Keytruda. The study found that the NPRL2 treatment decreased lung metastases but Keytruda had no effect. Additionally, a greater anti-tumor effect was seen in humanized compared to non-humanized mice, demonstrating that immune cells play a role in the effects of the NPRL2 nanoparticle therapy. Study findings suggest that NPRL2 gene therapy induces anti-tumor activity against KRAS/STK11 mutant tumors, which are resistant to many treatments, including Keytruda, through dendritic cell-mediated antigen presentation and cytotoxic immune cell activation. Another abstract to be presented by our clinical collaborators at the 2024 AACR meeting supports further clinical study of REQORSA in Anaplastic Lymphoma Kinase (“ALK”)+ NSCLC, which are found in approximately 5% of patients with NSCLC. In this nonclinical study, TUSC2 expression in three ALK+ cell lines were evaluated before and after exposure to REQORSA, referred to as TUSC2 gene therapy in the abstract. Researchers in the University of Michigan Rogel Cancer Center Judith Tam ALK NSCLC research initiative found that overexpressing TUSC2 via REQORSA treatment in ALK+ lung cancer cell lines had the ability to inhibit colony formation by 50%, which is believed to indicate that REQORSA inhibits growth of ALK+ cells. Researchers documented a strong pro-apoptotic response to TUSC2 expression in ALK+ NSCLC. The study found that the use of REQORSA to overexpress TUSC2 in ALK+ NSCLC cell lines was effective in decreasing cell growth and proliferation. The findings suggest REQORSA therapy may be a potential therapy for ALK+ NSCLC and the researchers believe the results support further clinical study of REQORSA as an anti-ALK NSCLC treatment strategy. Diabetes In July 2023, we exclusively licensed from the University of Pittsburgh technology related to a gene therapy for both Type 1 and Type 2 diabetes using a MafB promoter to drive expression of the Pdx1 and MafA transcription factors. In October 2023, we entered into a one-year extension to our August 2022 sponsored research agreement with the University of Pittsburgh for the use of GPX-002 in a NHP model in Type 2 diabetes. The extension includes a revised research plan to encompass the technologies to which we acquired exclusive rights from the University of Pittsburgh in July 2023. 25 Process Development and Manufacturing We have made substantial investment in manufacturing for our product candidates with the goal of mitigating the risks associated with the complex manufacturing required to deliver gene therapies. While we continue to use third-party contract development and manufacturing organizations (“CDMOs”) in the manufacture of our product candidates, we believe we have a competitive advantage in our field based on core competencies we have developed that we are leveraging in the manufacture of our product candidates. These core competencies include: ● Extensive and diverse internal and external consulting expertise; ● Customized chemistry, manufacturing and controls (“CMC”) strategy for accelerated development; ● Risk assessment and remediation for FDA submissions; ● Novel and proprietary manufacturing processes; ● Integrated global Good Manufacturing Practices (“cGMP” or “GMP”) manufacturing network; and ● Management of supply chain for business continuity. During 2023, we experienced a delay in the successful production of a new batch of REQORSA in connection with our transition to a third party CDMO with advanced and automated processes that we believe ultimately will allow us to more efficiently scale our product as we increase production for our trials. In December 2023, we completed the successful production of a new batch of REQORSA thereby securing REQORSA supply for our Acclaim clinical studies. In our oncology program, we are now focused on preparing for commercial readiness for REQORSA. To date we have developed a robust manufacturing process for REQORSA through years of process development activities that we continue to improve with the dramatic development and expansion of advanced technologies in the nascent gene therapy sector. REQORSA is an immunogene therapy with two main components. The active agent in REQORSA is a DNA plasmid encoding the TUSC2 protein. The plasmid is encapsulated by non-viral DOTAP cholesterol lipoplexes. This system of using lipoplexes to deliver the tumor suppressor gene-expressing plasmids to cancer cells is referred to by us as our systemic, non-viral ONCOPREX Delivery System. REQORSA has been shown to be scalable at cGMP and can be stored for approximately 12 to 18 months for later use. Successful tech transfer of REQORSA from MD Anderson, where it was developed and previously manufactured, to CDMOs has been achieved as well as scale-up of our clinical grade manufacturing production in accordance with cGMP. As noted above, the clinical grade material is being used to supply our Acclaim-1, Acclaim-2 and Acclaim-3 clinical trials. For our diabetes program, which is an earlier stage program than our oncology program, we are working with our academic collaborators at University of Pittsburgh to transfer the technologies associated with the manufacture of our GPX-002 construct to an appropriate integrated network of CDMOs and other vendors. This also involves the investigation of novel advanced technologies to incorporate in these processes. GPX-002 involves the delivery of the Pdx1 and MafA genes into the pancreas via the pancreatic duct utilizing an AAV vector. We manage our manufacturing arrangements with our CDMOs and other vendors through various agreements. Intellectual Property Patents and other proprietary rights such as trademarks and trade secrets are critical to our business and to our ability to successfully develop and commercialize our product candidates. Our goal is to obtain, maintain, enhance and enforce patent protection for our products, formulations, processes, methods and other proprietary technologies, preserve our trade secrets, and operate without infringing on the proprietary rights of other parties, both in the U.S. and in other countries. Our policy is to actively seek the broadest intellectual property protection possible for our product candidates, proprietary information, and proprietary technology through a combination of contractual arrangements, patents, trade secrets, trademarks, copyrights and regulatory exclusivity both in the U.S. and elsewhere in the world. Patents provide a period of exclusivity intended to make it more difficult for competitors to make, use or sell competing technologies. We additionally rely on regulatory protection afforded through data exclusivity, market exclusivity, orphan drug designation and/or patent term extensions, where available. We have developed and/or in-licensed numerous patents and pending patent applications that relate to compositions-of- matter, methods-of-use and other technologies and possess substantial know-how and trade secrets relating to the development of gene therapy technologies. As further described in the “Licenses and Research Collaborations” section below, we hold a worldwide, exclusive license from MD Anderson to patents covering the therapeutic use of TUSC2 and other genes that have been shown to have cancer fighting properties, including 20 issued patents and 12 pending patent applications for technologies developed at MD Anderson and The University of Texas Southwestern Medical Center. These patents comprise various therapeutic, diagnostic, technical and processing claims relating to REQORSA and our ONCOPREX Delivery System. We expect these patents and patent applications, if issued, to expire from 2024 to 2038. The rights we have obtained pursuant to our license agreement with MD Anderson are made subject to the rights of the U.S. government to the extent that the technology covered by the licensed intellectual property was developed under a funding agreement between MD Anderson and the U.S. government. As further described in the “Licenses and Research Collaborations” section below, we also hold worldwide, exclusive licenses to an issued patent and 8 pending patent applications for diabetes technologies developed at the University of Pittsburgh. We expect these patents and patent applications, if issued, to expire from 2035 to 2043. We also are prosecuting four patent applications relating to various oncology targets in our discovery program. In addition, for certain of our product candidates we also expect to have further exclusivity in the form of data and marketing exclusivity under pharmaceutical regulatory laws, including for example, potentially up to 12 years of exclusivity from the date of first BLA approval of our product candidates. For a further description and discussion of these laws, exclusivities and their regulatory background, please see the “Business – Government Regulation” section below in this Part I, Item 1 of this Annual Report. We also have received trademark registrations for the trademarks GENPREX, REQORSA, and ONCOPREX. For a discussion of the challenges we face in obtaining or maintaining patent, trademark and/or trade secret protection, please see the risk factors under the heading “Risks Related to Our Intellectual Property” in Part I, Item 1A of this Annual Report. 26 Licenses and Research Collaborations Agreements with MD Anderson Our ONCOPREX and REQORSA technologies are exclusively licensed pursuant to a Patent and Technology License Agreement dated July 20, 1994, with MD Anderson, as amended on September 1, 1996, August 11, 1997, July 31, 1994 and October 4, 2001 (collectively, the "1994 MD Anderson License Agreement"), between MD Anderson and Introgen Therapeutics, Inc. (f/k/a Intron Therapeutics, Inc.) (“Introgen”). Pursuant to the 1994 MD Anderson License Agreement, we have rights to patents covering use of various genes, including the TUSC2 gene, for treatment of cancer, as well as know-how and related intellectual property. The exclusive licenses under the 1994 MD Anderson License Agreement will continue until the expiration of all patents covered by such agreement. Upon the expiration of the exclusive licenses, we will have a non-exclusive, fully paid-up right and license to use and otherwise exploit the technology rights licensed under the agreement. MD Anderson may terminate the agreement for, among other things, a breach of the agreement by us which remains uncured. Pursuant to a Technology Sublicense Agreement dated March 7, 2007 (“Sublicense Agreement”), Introgen sublicensed its rights under the 1994 MD Anderson License Agreement to Introgen Research Institute, Inc. (“IRI”). IRI is a Texas-based technology company formed by Rodney Varner, our President and Chairman of the Board and IRI’s sole officer. IRI is owned by trusts of which Mr. Varner’s descendants are the sole beneficiaries. Pursuant to an Assignment and Collaboration Agreement dated April 13, 2009 (“IRI Collaboration Agreement”) IRI assigned its rights under the Sublicense Agreement to us, and we granted to IRI a non-exclusive, royalty-free license to use and practice the licensed technology for non-commercial research purposes. As consideration for this assignment, we agreed to assume all of IRI’s obligations to MD Anderson under the 1994 MD Anderson License Agreement, including ongoing patent related expenses and royalty obligations. The IRI Collaboration Agreement was amended by an Amended Collaboration and Assignment Agreement dated July 1, 2011 (“2011 IRI Collaboration Agreement”). The 2011 Collaboration Agreement provided that IRI would provide additional licensing opportunities and services to us, in return for monthly payments and our obligation to pay to IRI a royalty of 1% on sales of products licensed to us under the 1994 MD Anderson License Agreement. In 2012, IRI’s obligation to provide those opportunities and services, and our obligation to make monthly payments to IRI, were terminated; however, we are required to pay a 1% royalty to IRI upon sales of products licensed to us under the 1994 MD Anderson License Agreement which royalty obligation continues for 21 years after the later of the termination of the 1994 MD Anderson License Agreement and the termination of the sublicense assigned by IRI to us. Pursuant to a Technology Sublicense Agreement dated June 1, 2011, we granted to IRI a non-exclusive sublicense, for non-commercial purposes, to the rights under the Sublicense Agreement. At the time that we entered into the 2011 IRI Collaboration Agreement, Mr. Varner was not an officer or director of Genprex, but he was deemed to be an “affiliate” of the Company due to his beneficial ownership of approximately 39% of our issued and outstanding shares. At the time we acquired the ONCOPREX and REQORSA technologies under the 2009 IRI Collaboration Agreement, they were the subject of the Phase 1 Monotherapy Trial. We completed the Phase 1 Monotherapy Trial and did substantial process development, manufacturing and regulatory work necessary to bring the technologies into a Phase 1/2 combination trial. Pursuant to the 1994 MD Anderson License Agreement, the Sublicense Agreement and the 2009 IRI Collaboration Agreement, we are obligated to pay all fees, patent related expenses, royalties, and other amounts that become due with respect to the licensed patents, patent application and other technologies. We are also obligated to pay to MD Anderson royalties of 1.5% of net sales of the licensed products, as well as 1.5% of advance payments received by us (excluding amounts paid to us in reimbursement of development or other costs) from third parties pursuant to sublicense, marketing, distribution or franchise arrangements. Under the 2011 IRI Collaboration Agreement, we are obligated to pay to IRI a royalty of 1.0% of net sales of licensed products and 1.0% of certain other payments received by us. This royalty obligation continues for 21 years after the later of the termination of the 1994 MD Anderson License Agreement and the termination of the Sublicense Agreement. We have no other payment obligations to IRI under the 2009 IRI Collaboration Agreement or the 2011 IRI Collaboration Agreement. We were not required to make any up-front payments to MD Anderson or IRI when we entered into the 1994 MD Anderson License Agreement, the Sublicense Agreement or the 2009 IRI Collaboration Agreement. On May 4, 2020 (the “MD Effective Date”), we entered into a Patent and Technology License Agreement with MD Anderson, as amended on March 3, 2021 (collectively, the “2020 License Agreement” and together with the 1994 MD Anderson License Agreement, collectively, the “MD Anderson License Agreements”). Pursuant to the 2020 License Agreement, MD Anderson granted us a worldwide, exclusive, sublicensable, royalty-bearing license to certain licensed intellectual property and technology, including, without limitation, use of chemotherapy in combination with TUSC2 therapy and methods for treating cancer by administration of a TUSC2 in conjunction with EGFR inhibitors or other anti-cancer therapies in patients that are expected to be responsive to TUSC2 therapy (collectively, the “Licensed IP”), to manufacture, use, commercialize, seller, offer for sale and import licensed products related to the treatment of cancer using TUSC2 therapy in combination with certain immunotherapies (the “Licensed Products”). In consideration for our use of the Licensed IP, we are required to make certain payments to MD Anderson, including, without limitation, an upfront license fee as well as a fee paid to amend the agreement, annual maintenance fees ranging from the low five figures to low six figures, milestone payments aggregating up to a maximum of $6,150,000, low single digit royalty payments to low double digits royalty payments with lower net sales being subject to lower royalty payments, and minimum annual royalties after the first sale in a low six figure amount. In addition, we shall be required to reimburse MD Anderson for certain patent expenses. The 2020 License Agreement shall expire on the later to occur of (a) the expiration of all patents issued under the Licensed IP and the cancellation, withdrawal, or express abandonment of all patent applications under the Licensed IP, or (b) 30 years after the MD Effective Date, unless earlier terminated pursuant to the terms thereof. See also “Note 7 – Commitments and Contingencies” to our financial statements included in this Annual Report on Form 10-K. 27 License Agreement with P53, Inc. On February 26, 2010, IRI and P53, Inc., which subsequently changed its name to MultiVir Inc., (“P53”) entered into a Technology License Agreement (“P53 License Agreement”) pursuant to which IRI granted to P53 a worldwide, exclusive license under certain patents related to the ONCOPREX Delivery System that we are now using for the delivery of TUSC2, but only for P53’s use in gene therapy products in which the sole active genes are P53 and MDA-7. As a result of the 2009 IRI Collaboration Agreement, we are the licensor under the P53 License Agreement. The P53 License Agreement authorizes P53 to develop, make and have made, use, offer for sale, sell, import and otherwise distribute the licensed products. As consideration for the P53 License Agreement, P53 agreed to pay IRI one-half of all amounts invoiced by MD Anderson to IRI, up to a maximum of $15,000 to be paid by P53, for patent prosecution expenses incurred prior to the effective date of the P53 License Agreement, as well as two-thirds of IRI’s ongoing patent prosecution expenses, in each case with respect to the licensed patents. Additionally, P53 agreed to pay all amounts that become due to IRI as a result of the P53 License Agreement or the sales, licensing, or other activities of P53 under the P53 License Agreement. Pursuant to the P53 License Agreement, P53 has granted to IRI a fully paid license with respect to improvements made by P53 to the technology licensed to P53 under the P53 License Agreement. The P53 License Agreement remains in effect until the expiration of the last of the patents licensed under the agreement. The last licensed patent under the P53 License Agreement will expire in April 2025. We may terminate the agreement for, among other things, P53’s breach of the agreement or if P53 challenges the validity or enforceability of any of the licensed patents. P53 may terminate the agreement upon 90 days’ written notice. License Agreement with University of Pittsburgh - Of the Commonwealth System of Higher Education On February 11, 2020, we entered into an exclusive license agreement, as amended on August 17, 2022 and November 3, 2022 (collectively the “2020 UP License Agreement”), with the University of Pittsburgh - Of the Commonwealth System of Higher Education (“University of Pittsburgh” or “UP”) pursuant to which UP granted us a worldwide, exclusive license to certain licensed technology, and a worldwide, non-exclusive license to use certain related know-how, all related to diabetes gene therapy. The 2020 UP License Agreement permits us to prevent others from making, having made, using, and selling certain licensed technology in the field of diabetes therapy. We have agreed to sell the licensed technology to UP upon its request on terms and conditions as such products and/or processes are made available to our most favored customer. As consideration for the 2020 UP License Agreement, we agreed to pay UP an initial license fee, annual maintenance fees, running royalties minimum annual royalties beginning with the first commercial sale of the licensed technology pursuant to such agreement, a share of non-royalty sublicense income, and milestone payments in the aggregate amount of up to $3,975,000, as well as patent prosecution expenses incurred prior to and after the effective date of the 2020 UP License Agreement. The 2020 UP License Agreement shall remain in effect until the later of 20 years after the first commercial sale of the licensed technology or the expiration of the last Valid Claim (as defined in the 2020 UP License Agreement). UP may terminate the agreement if, among other things, (i) we fail to cure a default, (ii) if we fail to achieve the specified milestones within the specified time periods or (iii) our intentional practice of the licensed patent rights or know-how outside the field of diabetes therapy. We may terminate the 2020 UP License Agreement upon six months’ prior written notice to UP and payment of all amounts accrued or due to UP through the effective date of termination. On November 22, 2022 and December 29, 2022, respectively, we entered into two separate exclusive license agreements with UP on substantially similar terms as the 2020 UP License Agreement as described in the preceding paragraph. Both the exclusive license agreement dated November 22, 2022 (the “November 2022 UP License Agreement”) and the exclusive license agreement dated December 29, 2022 (the “December 2022 UP License Agreement”, and together with the 2020 UP License Agreement and the November 2022 UP License Agreement, collectively, the “UP License Agreements”) relate to diabetes gene therapy. The November 2022 UP License Agreement relates in particular to the transformation of macrophages enabling them to reduce autoimmunity activity in Type 1 diabetes while the December 2022 UP License Agreement relates to gene therapy for Type 2 diabetes using an insulin promoter to drive expression of the Pdx1 and MafA transcription factors. On July 14, 2023, we entered into an exclusive license agreement with UP (the “July 2023 UP License Agreement”) on substantially similar terms as the UP License Agreements as described in the preceding paragraphs. The July 2023 UP License Agreement related to a gene therapy for both Type 1 and Type 2 diabetes using a MafB promoter to drive expression of the Pdx1 and MafA transcription factors. See also “Note 7 – Commitments and Contingencies” to our financial statements included in this Annual Report on Form 10-K. 28 Grants Our technology discoveries and research and development programs have been the subject of numerous peer-reviewed publications and have been supported by Small Business Innovation Research ("SBIR") grants and grants from the National Institutes of Health ("NIH"), the United States Department of Treasury, and the State of Texas through its Texas Emerging Technology Fund. The rights we have obtained pursuant to our MD Anderson License Agreements are made subject to the rights of the U.S. government to the extent that the technology covered by the licensed intellectual property was developed under a funding agreement between MD Anderson and the U.S. government. Our collaborators at University of Pittsburgh have also received grants from the NIH in connection with preclinical work on GPX-002 and so, the rights we have obtained pursuant to our UP License Agreements are made subject to the rights of the U.S. government to the extent that the technology covered by the licensed intellectual property was developed under a funding agreement between the University of Pittsburgh and the U.S. government. Competition The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. There is also a strong emphasis on intellectual property and proprietary products. We have domestic and international competitors including major multinational pharmaceutical companies, established biotechnology companies, specialty pharmaceutical and generic drug companies and universities and other research institutions. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. Currently, there are a number of drugs approved and under development for treatment of lung cancer. Treatments competitive with our primary product candidates generally fall into the following categories: chemotherapies such as cisplatin, carboplatin, docetaxel and pemetrexed; targeted therapies such as Tarceva, Iressa, Gilotrif, and Tagrisso, and immunotherapies such as checkpoint inhibitors and CAR and CAR T cells, and oncolytic virus-based technology. Any such competing therapy may be more effective and/or cost- effective than ours. Type 1 diabetes is an autoimmune disease that permanently destroys beta cells of the pancreatic islet leading to the body no longer having the ability to produce insulin. Type 2 diabetes, also known as adult onset diabetes, is a condition associated with developed resistance to insulin. There are a number of approved treatments and therapies to manage diabetes including insulin, insulin analogs, continuous glucose monitoring, novel approaches to administration such as insulin pens and insulin pumps, and preventative therapeutics. Any of these therapies may be more effective, cost-effective, or considered less invasive than ours. Many of our competitors have greater financial and other resources, such as larger research and development staff and more experienced marketing and manufacturing organizations than we do. Large pharmaceutical companies, in particular, have extensive experience in clinical testing, obtaining regulatory approvals, recruiting patients and manufacturing pharmaceutical products. These companies also have significantly greater research, sales and marketing capabilities and collaborative arrangements in our target markets with leading companies and research institutions. Established pharmaceutical companies may also invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make the product candidates that we develop obsolete. As a result of these factors, our competitors may succeed in obtaining patent protection and/or FDA approval or discovering, developing and commercializing drugs for the cancer indications that we are targeting before we do or may develop drugs that are deemed to be more effective or gain greater market acceptance than ours. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies. In addition, many universities and private and public research institutes may become active in our target disease areas. Our competitors may succeed in developing, acquiring or licensing on an exclusive basis, technologies and drug products that are more effective or less costly than any product candidates that we are currently developing or that we may develop, which could render our products obsolete or noncompetitive. Any product candidates that we successfully develop and commercialize may compete with existing and new therapies that may become available in the future. The availability of reimbursement from government and other third-party payers will also significantly affect the pricing and competitiveness of our products. For a further discussion of the challenges we face from competition, please see the "Risk Factors" section in Part I, Item 1A of this Annual Report. 29 Government Regulation Government authorities in the U.S., at the federal, state and local level, and other countries extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, recordkeeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing and export and import of products such as those we are developing. The pharmaceutical drug product candidates that we develop must be approved by the FDA before they may be legally marketed. In the United States, the FDA regulates pharmaceutical products under the Federal Food, Drug, and Cosmetic Act (“FDCA”) and implementing regulations and other federal, state and local statutes and regulations. In the case of biologics, the section of the FDCA that governs the approval of drugs via New Drug Applications (“NDAs”) does not apply to the approval of biologics. Rather, biologics, such as gene therapy products, are approved for marketing under provisions of the Public Health Service Act (“PHSA”) via a Biologics License Application (“BLA”). However, the application process and requirements for approval of BLAs are very similar to those for NDAs. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, the approval process or after approval, may subject an applicant to administrative or judicial sanctions. FDA sanctions could include refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution injunctions, fines, refusals of government contracts, restitution, disgorgement and civil and criminal penalties. U.S. Biological Products Development Process The process required by the FDA before a biological product, including our REQORSA, GPX-002, and potential future product candidates, may be marketed in the United States generally involves the following: ● completion of nonclinical laboratory tests and animal studies according to Good Laboratory Practices (“GLPs”), and applicable requirements for the humane use of laboratory animals or other applicable regulations; ● submission to the FDA of an application for an IND, which must become effective before human clinical trials may begin; ● performance of adequate and well-controlled human clinical trials according to the FDA’s regulations, commonly referred to as Good Clinical Practices (“GCPs”) and any additional requirements for the protection of human research patients and their health information, to establish the safety, purity, and potency of the proposed biological product for its intended use; ● compiling of information demonstrating that the product can be properly formulated, manufactured and stored; ● submission to the FDA of a BLA for marketing approval that includes substantive evidence of safety, purity, and potency from results of nonclinical testing and clinical trials; ● satisfactory completion of an FDA inspection of the manufacturing facility or facilities where the product is produced and tested to assess compliance with GMP requirements to assure that the facilities, methods and controls are adequate to preserve the product’s identity, strength, quality and purity; ● potential FDA audit of the nonclinical and clinical trial sites that generated the data in support of the BLA; and ● FDA review and approval, or licensure, of the BLA. 30 Within the FDA, the Center for Biologics Evaluation and Research (“CBER”) regulates gene therapy products. The FDA has published guidance documents related to, among other things, gene therapy products in general, their preclinical assessment, observing patients involved in gene therapy studies for delayed adverse events, potency testing, and chemistry, manufacturing and control information in gene therapy INDs. Before testing any product candidate, including a gene therapy product, in humans, the product candidate enters the preclinical testing stage. Preclinical tests, which are a subset of nonclinical studies, include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies to assess the potential safety and activity of the product candidate. The conduct of certain preclinical tests must comply with federal regulations and requirements, including GLPs. The clinical trial sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. Some nonclinical testing usually continues after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA places the clinical trial on a clinical hold within that 30-day time period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. The FDA may also impose clinical holds on a product candidate at any time before or during clinical trials due to safety concerns or non-compliance. If the FDA imposes a clinical hold, trials may not recommence without FDA authorization and then only under terms authorized by the FDA. Clinical trials involve the administration of the product candidate to volunteers or patients under the supervision of qualified investigators, generally physicians not employed by or under the clinical trial sponsor’s control. Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, patient selection and exclusion criteria, effectiveness criteria to be evaluated, and the parameters to be used to monitor patient safety, including stopping rules that assure a clinical trial will be stopped if certain adverse events occur. Each protocol and any amendments to the protocol must be submitted to the FDA as part of the IND. Clinical trials must be conducted and monitored in accordance with the FDA’s regulations comprising the GCP requirements, including the requirement that all patients provide informed consent. The FDA may order the temporary or permanent discontinuation of a clinical trial at any time, or impose other sanctions, if it believes that the clinical trial either is not being conducted in accordance with FDA regulations or presents an unacceptable risk to the clinical trial patients. Further, each clinical trial must be reviewed and approved by an independent institutional review board ("IRB") at or servicing each institution or site at which the clinical trial will be conducted. An IRB is charged with protecting the welfare and rights of clinical trial participants and considers such items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the form and content of the informed consent, which must be signed by each clinical trial patient or his or her legal representative, and must monitor the clinical trial until completed. Clinical trials involving biological product candidates also must be reviewed by an institutional biosafety committee (“IBC”), a local institutional committee that reviews and oversees basic and clinical research conducted at that institution. The IBC assesses the safety of the research and identifies any potential risk to public health or the environment. 31 Clinical trials to support BLAs for marketing approval are typically conducted in three sequential phases that may overlap or be combined: ● Phase 1. The investigational product candidate is initially introduced into human patients and tested to assess metabolism, pharmacokinetics, pharmacological actions, side effects associated with drug exposure, and to obtain early evidence of a treatment effect if possible. In the case of some products for severe or life-threatening diseases, especially when the product candidate may be inherently too toxic to be ethically administered to healthy volunteers, the initial human testing is often conducted in patients; gene therapy is usually administered to patients in Phase 1 trials. This is also true in situations where toxicity can only be judged in patients with disease. An evaluation for preliminary evidence of efficacy can be performed at this time. ● Phase 2. The investigational product candidate is evaluated in a limited patient population to identify possible common adverse effects and safety risks, to evaluate preliminarily the efficacy of the product candidate for specific targeted diseases, and to generate hypotheses for the dosage tolerance, optimal dosage, and dosing schedule. ● Phase 3. Clinical trials are undertaken to evaluate further dosage, clinical efficacy, potency, and safety in an expanded patient population at geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the product candidate and provide an adequate basis for product labeling. In most cases, the FDA requires two adequate and well-controlled Phase 3 clinical trials to demonstrate the efficacy of the drug. A single trial may be sufficient in some instances, including (1) where the study is a large multicenter trial demonstrating internal consistency and a statistically very persuasive finding of a clinically meaningful effect on mortality, irreversible morbidity or prevention of a disease with a potentially serious outcome and confirmation of the result in a second trial would be practically or ethically impossible or (2) when there is one adequate and well-controlled clinical investigation plus other confirmatory evidence. Typically, during the development of oncology therapies, all subjects enrolled in Phase 1 clinical trials are disease-affected patients and, as a result, considerably more information on clinical activity may be collected during such trials than during Phase 1 clinical trials for non-oncology therapies. A single pivotal trial may be sufficient in rare instances to provide substantial evidence of effectiveness (generally subject to the requirement of additional post-approval studies). In addition, the manufacturer of an investigational biologic in a Phase 2 or Phase 3 clinical trial for a serious or life-threatening disease is required to make available, such as by posting on its website, its policy on evaluating and responding to requests for expanded access to such investigational biologic. Post-approval clinical trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These clinical trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication, particularly for long-term safety follow-up. The FDA recommends that sponsors observe patients for potential gene therapy-related delayed adverse events with agents such as those we are developing for a period of up to 15 years, including a minimum of five years of annual examinations followed by ten years of annual queries, either in person or by questionnaire, of clinical trial patients. During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data, and clinical trial investigators. Annual progress reports detailing the results of the clinical trials must be submitted to the FDA. Written IND safety reports must be promptly submitted to the FDA, and the investigators for serious and unexpected adverse events, any findings from other trials, tests in laboratory animals or in vitro testing that suggest a significant risk for human patients, or any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. The sponsor must submit an IND safety report within 15 calendar days after the sponsor determines that the information qualifies for expedited reporting. The sponsor must also notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction within seven calendar days after the sponsor’s initial receipt of the information. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The FDA, the sponsor, or its data safety monitoring board may suspend a clinical trial at any time on various grounds, including a finding that the patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the investigational product candidate has been associated with unexpected serious harm to patients. 32 Concurrently with clinical trials, companies usually complete additional animal studies and also develop additional information about the physical characteristics of the components of a product as well as finalize processes for manufacturing the components in commercial quantities in accordance with GMP requirements. To help reduce the risk of the introduction of adventitious agents with use of biological products, the PHSA, emphasizes the importance of manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the sponsor must develop methods for testing the identity, strength, quality, potency and purity of the final product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the components of a product candidate do not undergo unacceptable deterioration over their shelf life. U.S. Review and Approval Processes After the completion of clinical trials of an investigational biologic product, a BLA is prepared and submitted to the FDA. FDA approval of a BLA must be obtained before commercial marketing and distribution of the product may begin in the United States. The BLA must include results of product development, laboratory, and animal studies, human trials, information on the manufacture and composition of the product, proposed labeling and other relevant information. The testing and approval processes require substantial time and effort and there can be no assurance that the FDA will file the BLA and, even if filed, that any approval will be granted on a timely basis, if at all. Under the Prescription Drug User Fee Act, as amended (“PDUFA”), each BLA must be accompanied by a significant user fee. The FDA adjusts the PDUFA user fees on an annual basis. PDUFA also imposes annual program fees on prescription drugs, including biologics. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a small business. No user fees are assessed on BLAs for products designated as orphan drugs, unless the application also includes a non-orphan indication. Within 60 days following submission, the FDA reviews the BLA to determine if it is substantially complete before the agency files it. The FDA may request additional information or may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission. In this event, the BLA must be resubmitted with the additional information. The resubmitted application also is subject to an initial filing review before the FDA files it. Once the submission is filed, the FDA begins an in-depth substantive review of the BLA. Under PDUFA, FDA has agreed to performance goals to review 90% of original standard BLAs within 10 months of the 60-day filing date and 90% of original priority BLAs within six months of the 60-day filing date, whereupon a review decision is to be made. The FDA does not always meet its PDUFA goal dates for standard and priority BLAs. The review process and the PDUFA goal date may be extended by three months if the FDA requests or the BLA sponsor otherwise provides additional information or clarification regarding information already provided in the BLA submission. The FDA reviews the BLA to determine, among other things, whether the proposed product is safe and potent, or effective, for its intended use, and has an acceptable purity profile, and whether the product is being manufactured in accordance with GMP to assure and preserve the product’s identity, safety, strength, quality, potency and purity. 33 The FDA may refer applications for novel products or products that present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations when making decisions. During the product approval process, the FDA also will determine whether a Risk Evaluation and Mitigation Strategy (“REMS”) is necessary to assure that the benefits of the biologic outweigh the potential risks of the product to patients. A REMS can include medication guides, communication plans for healthcare professionals, and elements to assure a product’s safe use (“ETASU”). An ETASU can include, but is not limited to, special training or certification for prescribing or dispensing the product, dispensing the product only under certain circumstances, special monitoring, and the use of patient- specific registries. If the FDA concludes that a REMS is needed, the sponsor of the BLA must submit a proposed REMS; the FDA will not approve the BLA without a REMS, if required. Before approving a BLA, the FDA will typically inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in substantial compliance with GMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites, to assure that the clinical trials were conducted in compliance with GCP requirements. In addition, the FDA may inspect one or more sites where animal studies were conducted to confirm compliance with GLP requirements. To assure GMP, GCP and GLP compliance, an applicant must incur significant expenditure of time, money, and effort in the areas of training, record keeping, production, and quality control. Notwithstanding the submission of relevant data and information, the FDA may ultimately decide that the BLA does not satisfy its regulatory criteria for approval and deny approval. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently from how we interpret the same data. If the agency decides not to approve the BLA in its present form, the FDA will issue a complete response letter that usually describes all of the specific deficiencies in the BLA identified by the FDA. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical trials. Additionally, the complete response letter may include recommended actions that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the applicant may resubmit the BLA, addressing all of the deficiencies identified in the letter, withdraw the application, or request a hearing. If a product candidate receives regulatory approval, the FDA will issue an approval letter. The approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings, or precautions be included in the product labeling. The FDA may impose restrictions and conditions on product distribution, prescribing, or dispensing in the form of a risk management plan, or otherwise limit the scope of any approval. In addition, the FDA may require post marketing clinical trials, sometimes referred to as Phase 4 clinical trials, designed to assess further a biological product’s safety and effectiveness, and testing and surveillance programs to monitor the safety of approved products that have been commercialized. Expedited Development and Review Programs The FDA has four programs in place intended to facilitate and expedite development and review of new drugs and biologics intended to address unmet medical needs in the treatment of serious or life-threatening conditions. These are Fast Track Designation, Breakthrough Therapy Designation, Accelerated Approval Program, and Priority Review Designation. The Fast Track program is intended to expedite or facilitate the process for reviewing a new product if it is intended for the treatment of a serious or life-threatening disease or condition, and it demonstrates the potential to address unmet medical needs for such a disease or condition. Fast Track Designation applies to the combination of the product and the specific indication for which it is being studied. The sponsor of a new drug or biologic may request the FDA to designate the drug or biologic as a Fast Track product at any time during the clinical development of the product. Unique to a Fast Track product, the FDA may consider for review sections of the marketing application on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the application, the FDA agrees to accept sections of the application and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the application. A product can receive Breakthrough Therapy Designation if it is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that it may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. A Breakthrough Therapy Designation conveys all of the features of Fast Track Designation in addition to more intensive FDA guidance on an efficient development program, organizational commitment involving senior managers, and eligibility for priority review. Specifically, the FDA intends to expedite the development and review of a Breakthrough Therapy by, where appropriate, intensively involving senior managers and experienced review staff in a proactive collaborative, cross-disciplinary review. Where appropriate, the FDA also intends to assign a cross-disciplinary project lead for the review team to facilitate an efficient review of the development program. The FDA notes that a compressed drug development program still must generate adequate data to demonstrate that the drug or biologic meets the statutory standard for approval. Omitting components of the development program that are necessary for such a determination can significantly delay, or even preclude, marketing approval. 34 Breakthrough Therapy Designation indicates that preliminary clinical evidence demonstrates the drug may have substantial improvement on one or more clinically significant endpoints over available therapy. Breakthrough Therapy Designation intensifies FDA involvement to ensure an efficient drug development program and is an organizational commitment from the FDA to involve its senior managers. A sponsor receiving Breakthrough Therapy Designation has up to six months after receiving the Breakthrough Therapy Designation to request an Initial Comprehensive Multidisciplinary meeting to discuss the drug development program. This initial meeting is a Type B meeting, used to discuss the overarching, high-level plan for drug development. These discussions include topics such as planned clinical trials and endpoints, any resizing or adaptations to the trials, plans for expediting the manufacturing development strategy and studies that potentially could be completed after approval. When Breakthrough Therapy Designation has been granted, the FDA is encouraged to meet regularly with the sponsor and subsequent meetings are considered Type B meetings and are established based on the needs of the program. The FDA may grant accelerated approval under its Accelerated Approval Program to a product candidate for a serious or life-threatening condition upon a determination that the product candidate has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or an effect on a clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. Accelerated approval is contingent on a sponsor’s agreement to conduct at least one adequate and well-controlled additional post-approval trial to verify and describe the product’s clinical benefit. In addition, the FDA currently requires as a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch of the product. Fast Track Designation, Breakthrough Therapy Designation, RMAT, and Accelerated Approval do not change the standards for approval but may expedite the development process. Additionally, Fast Track Designation or Breakthrough Therapy Designation may be withdrawn by the FDA if the FDA believes that the designation is no longer supported by data emerging in the clinical trial process, including considering any new drug or biologic approvals that address the unmet medical need. An application for a product candidate may be eligible to obtain Priority Review Designation if it is intended to treat a serious condition and, if approved, would provide a significant improvement in safety or effectiveness. The FDA will attempt to direct additional resources to the evaluation of an application for a new product designated for priority review in an effort to facilitate the review. A Priority Review Designation means FDA’s goal is to take action on the marketing application within six months (compared to ten months under standard review) of the 60-day filing date. Priority Review Designation does not change the standards for approval but may expedite the review process. Orphan Designation and Exclusivity Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, defined as a disease or condition with a patient population of fewer than 200,000 individuals in the United States, or a patient population greater than 200,000 individuals in the United States and when there is no reasonable expectation that the cost of developing and making available the drug or biologic in the United States will be recovered from sales in the United States for that drug or biologic. Orphan drug designation must be requested before submitting a BLA or NDA. After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease for which it has such designation, the product is entitled to orphan product marketing exclusivity, which means that the FDA may not approve any other applications, including a full BLA, to market the same biologic for the same use or indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity or if FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or biologic for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the BLA or NDA application user fee. A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. In addition, orphan drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or, as noted above, if the second applicant demonstrates that its product is clinically superior to the approved product with orphan exclusivity or the manufacturer of the approved product is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition. Post-Approval Requirements Once a BLA is approved, maintaining post-approval compliance with applicable federal, state, and local statutes and regulations requires the expenditure of substantial time and financial resources. Manufacturers and other entities involved in the manufacture and distribution of approved products are required to register the establishments where the approved products are made with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with GMP and other laws. Rigorous and extensive FDA regulation of products continues after approval, particularly with respect to GMP. We rely, and expect to continue to rely, on third parties for the production and distribution of clinical and commercial quantities of any products that we may commercialize. Manufacturers of our products are required to comply with applicable requirements in the GMP regulations, including quality control and quality assurance and maintenance of records and documentation. Other post-approval requirements include reporting of GMP deviations that may affect the identity, potency, purity and overall safety of a distributed product, record-keeping requirements, reporting of adverse effects, reporting updated safety and efficacy information, and complying with electronic record and signature requirements. After a BLA is approved, the product also may be subject to official lot release. As part of the manufacturing process, the manufacturer is required to perform certain tests on each lot of the product before it is released for distribution. If the product is subject to official release by the FDA, the manufacturer submits samples of each lot of product to the FDA together with a release protocol showing a summary of the history of manufacture of the lot and the results of all of the manufacturer’s tests performed on the lot. The FDA also may perform certain confirmatory tests on lots of some products before releasing the lots for distribution by the manufacturer. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain GMP compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved BLA, including withdrawal of the product from the market. In addition, changes to the manufacturing process or facility generally require prior FDA approval before being implemented. Other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval. 35 We also must comply with the FDA’s advertising and promotion requirements, such as those related to direct-to-consumer advertising, the prohibition on promoting products for uses or in patient populations that are not described in the product’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities, and promotional activities involving the internet. Discovery of previously unknown problems or the failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible civil or criminal sanctions. Failure to comply with the applicable U.S. requirements after approval may subject an applicant or manufacturer to administrative or judicial civil or criminal sanctions and adverse publicity. FDA sanctions could include refusal to approve pending applications, withdrawal of an approval, clinical hold, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, mandated corrective advertising or communications with doctors, debarment, restitution, disgorgement of profits, or civil or criminal penalties. U.S. Patent Term Restoration Depending upon the timing, duration, and specifics of the FDA approval of the use of our current and potential product candidates, some of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984 ("Hatch-Waxman Amendments"). The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the effective date of an IND and the submission date of a BLA plus the time between the submission date of a BLA and the approval of that application. Only one patent applicable to an approved biological product is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The U.S. Patent and Trademark Office, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. Biosimilars and Exclusivity The Biologics Price Competition and Innovation Act of 2009 ("BPCIA") created an abbreviated approval pathway for biological products shown to be highly similar to, or interchangeable with, an FDA-licensed reference biological product. The FDA has issued several guidance documents outlining an approach to review and approval of biosimilars. Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity, and potency, can be shown through analytical studies, animal studies, and a clinical study or studies. Interchangeability requires that a product is biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product in any given patient and, for products that are administered multiple times to an individual, the biologic and the reference biologic may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic. 36 The BPCIA includes, among other provisions: ● A 12-year exclusivity period from the date of first licensure, or BLA approval, of the reference product, during which approval of a 351(k) application referencing that product may not be made effective; ● A four-year exclusivity period from the date of first licensure of the reference product, during which a 351(k) application referencing that product may not be submitted; and ● An exclusivity period for certain biological products that have been approved through the 351(k) pathway as interchangeable biosimilars. The BPCIA also establishes procedures for identifying and resolving patent disputes involving applications submitted under section 351(k) of the PHSA. The BPCIA is complex and its interpretation and implementation by the FDA remains unpredictable. In addition, government proposals have sought to reduce the 12-year reference product exclusivity period. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate effect, implementation, and meaning of the BPCIA is subject to uncertainty. Disclosure of Clinical Trial Information Sponsors of clinical trials of FDA-regulated products, including biological products, are required to register and disclose certain clinical trial information on the website www.clinicaltrials.gov. Information related to the product, patient population, phase of investigation, trial sites and investigators, and other aspects of a clinical trial are then made public as part of the registration. Sponsors are also obligated to disclose the results of their clinical trials after completion. Disclosure of the results of clinical trials can be delayed in certain circumstances for up to two years after the date of completion of the trial. Competitors may use this publicly available information to gain knowledge regarding the progress of clinical development programs as well as clinical trial design. Pediatric Information Under the Pediatric Research Equity Act (“PREA”), BLAs or supplements to BLAs must contain data to assess the safety and effectiveness of the biological product for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the biological product is safe and effective. The FDA may grant full or partial waivers, or deferrals, for submission of data. Unless otherwise required by regulation, PREA does not apply to any biological product with orphan product designation except a product with a new active ingredient that is a molecularly targeted cancer product intended for the treatment of an adult cancer and directed at a molecular target determined by FDA to be substantially relevant to the growth or progression of a pediatric cancer that is subject to a BLA submitted on or after August 18, 2020. The Best Pharmaceuticals for Children Act (“BPCA”) provides a six-month extension of any non-patent exclusivity for a biologic if certain conditions are met. Conditions for exclusivity include the FDA’s determination that information relating to the use of a new drug or biologic in the pediatric population may produce health benefits in that population, the FDA making a written request for pediatric studies, and the applicant agreeing to perform, and reporting on, the requested studies within the statutory timeframe. Applications under the BPCA are treated as priority applications, with all of the benefits that designation confers. 37 Additional U.S. Regulation In the United States, our activities are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including but not limited to, the Centers for Medicare and Medicaid Services (“CMS”), other divisions of the U.S. Department of Health and Human Services, for instance the Office of Inspector General, the U.S. Department of Justice (“DOJ”), and individual U.S. Attorney offices within the DOJ, and state and local governments. For example, sales, marketing and scientific/educational grant programs must comply with the anti-fraud and abuse provisions of the Social Security Act, the false claims laws, the physician payment transparency laws, the privacy and security provisions of the Health Insurance Portability and Accountability Act (“HIPAA”), as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”) and similar state laws, each as amended. In addition to the foregoing, state and federal laws regarding environmental protection and hazardous substances, including the Occupational Safety and Health Act, the Resource Conservancy and Recovery Act and the Toxic Substances Control Act, may affect our business. These and other laws govern our use, handling and disposal of various biological, chemical, and radioactive substances used in, and wastes generated by, our operations. If our operations result in contamination of the environment or expose individuals to hazardous substances, we could be liable for damages and governmental fines. Federal and State Fraud and Abuse, Privacy and Transparency Laws Federal and state fraud and abuse laws, which generally will not be applicable to us or our current and potential product candidates unless and until we obtain FDA marketing approval for any of our current and potential product candidates, include, among others, anti-kickback statutes, the False Claims Act and related stated state and federal laws, the Stark Law and related state and federal laws, transparency laws, privacy and regulation regarding providing drug samples, sales and marketing activities and our relationships with customers and payors as follows. The federal Anti-Kickback Statute prohibits, among other things, individuals and entities from knowingly and willfully offering, paying, soliciting, or receiving any remuneration, directly or indirectly, overtly or covertly, to induce or in return for purchasing, leasing, recommending, ordering, or arranging for the purchase, lease, recommendation or order of any health care item or service reimbursable, in whole or in part, under Medicare, Medicaid, or other federally financed healthcare programs. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. Although there are a number of statutory exemptions and regulatory safe harbors protecting certain common activities from prosecution, the exemptions and safe harbors are drawn narrowly, and practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exemption or safe harbor. Additionally, the intent standard under the Anti-Kickback Statute was amended by the Affordable Care Act to a stricter standard such that a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. Further, the Affordable Care Act codified case law that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act. HIPAA created additional federal criminal statutes that prohibit, among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud or to obtain, by means of false or fraudulent pretenses, representations or promises, any money or property owned by, or under the control or custody of, any healthcare benefit program, including private third-party payers, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up by trick, scheme or device, a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. 38 Federal false claims and civil monetary penalties laws, including the federal civil False Claims Act, prohibit, among other things, any person or entity from knowingly presenting, or causing to be presented, a false, fictitious or fraudulent claim for payment to, or approval by, the federal government, or knowingly making, using, or causing to be made or used, a false statement to get a false claim paid. Several pharmaceutical and other health care companies have been prosecuted under these laws for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted because of the company’s marketing of the product for unapproved, and thus non-reimbursable, uses. The majority of states also have statutes or regulations similar to the federal Anti-Kickback Statute and false claims laws, which apply to items and services, reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payer. We may also be subject to data privacy and security regulations by both the federal government and the states in which we conduct our business. HIPAA, as amended by HITECH, and their respective implementing regulations, including the final Omnibus Rule published in 2013, imposes requirements on certain types of entities, including mandatory contractual terms, relating to the privacy, security, and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s security standards and certain privacy standards directly applicable to business associates, which are independent contractors or agents of covered entities that create, receive, maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity. HITECH also created four new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, many state laws govern the privacy and security of health information in specified circumstances, many of which differ from each other and from HIPAA in significant ways and may not have the same requirements, thus complicating compliance efforts. Additionally, the federal Physician Payments Sunshine Act and its implementing regulations require that certain manufacturers of drugs, devices, biological and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with certain exceptions, annually report to CMS information related to certain payments or other transfers of value made or distributed to physicians, physician assistants, certain types of advanced practice nurses and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and teaching hospitals and to report annually certain ownership and investment interests held by physicians and their immediate family members. Failure to submit timely, accurately, and completely the required information may result in civil monetary penalties of up to an aggregate of $150,000 per year and up to an aggregate of $1 million per year for “knowing failures.” Certain states also mandate implementation of compliance programs, impose restrictions on pharmaceutical manufacturer marketing practices, and/or require the tracking and reporting of gifts, compensation, and other remuneration to healthcare providers and entities. Because of the breadth of these laws and the narrowness of the exceptions and safe harbors, it is possible that some of our business activities could be subject to challenge under one or more of such laws. Such a challenge could have a material adverse effect on our business, financial condition, and results of operations. If our operations are found to be in violation of any of these or any other health regulatory laws that may apply to us, we may be subject to, without limitation, significant penalties, including the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, disgorgement, individual imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. In addition, as part of the sales and marketing process, pharmaceutical companies frequently provide samples of approved products to physicians. This practice is regulated by the FDA and other governmental authorities, including, in particular, requirements concerning record keeping and control procedures. Any failure to comply with the regulations may result in significant criminal and civil penalties as well as damage to our credibility in the marketplace. 39 Coverage and Reimbursement In many of the markets where we may do business in the future, the prices of pharmaceutical products are subject to direct price controls (by law) and to reimbursement programs with varying price control mechanisms. In the United States, significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain product approval. Often private payers follow the coverage and reimbursement decisions of the Medicare program, and it is difficult to predict how CMS may decide to cover and reimburse approved products, especially novel products, and those determinations are subject to change. Moreover, the process for determining whether a third-party payer will provide coverage for a drug product may be separate from the process for setting the price of a drug product or for establishing the reimbursement rate that such a payer will pay for the drug product. Third-party payers may limit coverage to specific products on an approved list, also known as a formulary, which might not include all of the FDA-approved drugs for a particular indication. A decision by a third-party payer not to cover our current and potential product candidates could reduce physician utilization of our products once approved. A payer’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Further, one payer’s determination to provide coverage for a drug product does not assure that other payers will also provide coverage for the drug product. Coverage and reimbursement for new products can differ significantly from payer to payer. As a result, the coverage determination process will require us to provide scientific and clinical support for the use of our products to each payer separately and will be a time-consuming process. Additionally, third-party reimbursement may not be available or may not be adequate to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development. Federal, state and local governments in the United States and foreign governments continue to consider legislation to limit the growth of healthcare costs, including the cost of prescription drugs. Specifically, there have been several recent U.S. Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. Future legislation could limit payments for pharmaceuticals such as the drug candidates that we are developing. Different pricing and reimbursement schemes exist in other countries. In the EU, governments influence the price of drug products through their pricing and reimbursement rules and control of national health care systems that fund a large part of the cost of those products to consumers. Some jurisdictions operate systems under which products may be marketed only after a reimbursement price has been agreed. To obtain reimbursement or pricing approval, some of these countries may require the completion of studies or analyses of clinical trials that compare the cost-effectiveness of a particular product candidate to currently available therapies. Other member states allow companies to set their own prices for medicines, but exert cost controls in other ways, including but not limited to, placing revenue caps on product sales, providing reimbursement for only a subset of eligible patients, mandating price negotiations after a set period of time, or mandating that prices not exceed an average basket of prices in other countries. The downward pressure on health care costs in general, particularly treatments, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, European governments may periodically review and decrease prices based on factors, including, but not limited to, years-on-market, price in other countries, competitive entry, new clinical data, lack of supporting clinical data, or other factors. The marketability of any product candidates for which we or our collaborators receive regulatory approval for commercial sale may suffer if the government and third-party payers fail to provide adequate coverage and reimbursement. In addition, an emphasis on cost containment measures in the United States has increased and we expect will continue to increase the pressure on pharmaceutical pricing. Third-party payers are increasingly challenging the prices charged for medical products and services, examining the medical necessity and reviewing the cost-effectiveness of drugs, medical devices and medical services, in addition to questioning safety and efficacy. If these third-party payers do not consider our products to be cost-effective compared to other available therapies, they may not cover our products after FDA approval or, if they do, the level of payment may not be sufficient to allow us to sell our products at a profit. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we or our collaborators receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future. 40 Legislative and Regulatory Changes, Including Health Care Reform The laws and regulation that affect our business are subject to change from time to time, and entirely new laws and regulations are sometimes adopted. In particular, healthcare reforms that have been adopted, and that may be adopted in the future, could result in further reductions in coverage and levels of reimbursement for pharmaceutical products, increases in rebates payable under U.S. government rebate programs and additional downward pressure on pharmaceutical product prices. In 2022, President Biden signed the Inflation Reduction Act, which, among other things, contains a provision that authorizes CMS to negotiate a "maximum fair price" for a limited number of high-cost, single- source drugs each year, and another provision that requires drug companies to pay rebates to Medicare if prices rise faster than inflation. It is unclear to what extent these and other statutory, regulatory, and administrative initiatives will be enacted and implemented in future years. Environmental Regulation In addition to the foregoing, state and federal laws regarding environmental protection and hazardous substances, including the Occupational Safety and Health Act, the Resource Conservancy and Recovery Act and the Toxic Substances Control Act, may affect our business. These and other laws govern our use, handling and disposal of various biological, chemical, and radioactive substances used in, and wastes generated by, our operations. If our operations result in contamination of the environment or expose individuals to hazardous substances, we could be liable for damages and governmental fines. U.S. Foreign Corrupt Practices Act and Similar International Laws The U.S. Foreign Corrupt Practices Act, to which we are subject, prohibits corporations and individuals from engaging in certain activities to obtain or retain business or to influence a person working in an official capacity. It is illegal to pay, offer to pay or authorize the payment of anything of value to any foreign government official, government staff member, political party, or political candidate in an attempt to obtain or retain business or to influence otherwise a person working in an official capacity. Other countries, including a number of EU member states, have laws of similar application, including anti-bribery or anti-corruption laws such as the UK Bribery Act. The UK Bribery Act prohibits giving, offering, or promising bribes to any person, as well as requesting, agreeing to receive, or accepting bribes from any person. Under the UK Bribery Act, a company that carries on a business or part of a business in the United Kingdom may be held liable for bribes given, offered or promised to any person in any country by employees or other persons associated with the company in order to obtain or retain business or a business advantage for the company. Liability under the UK Bribery Act is strict, but a defense of having in place adequate procedures designed to prevent bribery is available. 41 Government Regulation Outside of the United States In addition to regulations in the United States, we will be subject to a variety of regulations in other jurisdictions governing, among other things, clinical trials and any commercial sales and distribution of our products. Because biologically sourced raw materials are subject to unique contamination risks, their use may be subjected to different types of restrictions in different countries. Whether or not we obtain FDA approval for a product, we must obtain the required approvals from regulatory authorities in foreign countries prior to the commencement of clinical trials or marketing of the product in those countries. Certain countries outside of the United States have a similar process that requires the submission of a clinical trial application equivalent to an IND prior to the commencement of human clinical trials. In the European Union, for example, a clinical trial authorization, or CTA, must be submitted to each country’s national health authority and an independent ethics committee, much like the FDA and the IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, clinical trials may start. The requirements and process governing the conduct of clinical trials, product licensing, manufacturing, sales and marketing, pricing, and reimbursement vary from country to country. In all cases, the clinical trials are to be conducted in accordance with GCP, applicable regulatory requirements, and the ethical principles that have their origin in the Declaration of Helsinki. If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension, or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution in those countries. Employees and Human Capital As of March 15, 2024, we had 26 total employees, all of which were full-time. We are not a party to any collective bargaining agreements. We believe that we maintain good relations with our employees. Our employees are highly skilled, with many holding advanced degrees and having experience in drug development. We anticipate that the number of employees will remain approximately at this level throughout this year even as we progress our product pipeline. We believe that our success depends in large part on our ability to attract and retain experienced and skilled employees. We endeavor to provide competitive compensation and benefits packages that reflect the highly competitive nature of our industry, as well as opportunities for professional development which are designed to attract, engage, retain and reward talented individuals who possess the skills necessary to support our business objectives, assist in the achievement of our strategic goals and increase stockholder value. We employ a pay for performance philosophy. Annual salary increases, promotional opportunities, incentive bonuses and stock option grants are available to all employees and are based on merit and include individual and corporate performance factors. Much of our success is rooted in the diversity of our teams and our commitment to inclusion. We are committed to providing an environment of mutual respect and equal opportunity. We value diversity at all levels and continue to focus on extending our diversity and inclusion initiatives across our entire workforce. We believe that our business benefits from the different perspectives that a diverse workforce brings. 42 Corporate Information and Available Information.

Below we summarize what we believe are the principal risk factors but these risks are not the only ones we face, and you should carefully review and consider the full discussion of our risk factors in the section titled “Risk Factors,” together with the other information in this Annual Report on Form 10-K. If any of the following risks actually occurs (or if any of those listed elsewhere in this Annual Report on Form 10-K occur), our business, reputation, financial condition, results of operations, revenue, and future prospects could be seriously harmed. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. Risks Related to Our Operations and Need for Additional Capital ● We will require substantial additional funding, which may not be available to us on acceptable terms, or at all, and, if not so available, may require us to delay, limit, reduce or cease our operations. ● Our recurring losses from operations have raised substantial doubt regarding our ability to continue as a going concern. ● We have never been profitable, we have no products approved for commercial sale, and to date we have not generated any revenue from product sales. As a result, our ability to reduce our losses and reach profitability is unproven, and we may never achieve or sustain profitability. ● We have a limited operating history and we expect a number of factors to cause our operating results to fluctuate on an annual basis, which may make it difficult to predict our future performance. ● Our ability to utilize our net operating loss carryforwards may be limited, resulting in income taxes sooner than currently anticipated. Risks Related to Development and Commercialization of Our Current and Future Product Candidates ● Our success depends greatly on the success of our development of REQORSA for the treatment of NSCLC and SCLC, and our other product candidates, including GPX-002 for the treatment of diabetes. ● If we are unable to secure contract manufacturers with capabilities to produce the products that we require, we could experience delays in conducting our planned clinical trials. ● Negative public opinion and increased regulatory scrutiny of gene therapy and genetic research may damage public perception of our current and potential product candidates or adversely affect our ability to conduct our business or obtain regulatory approvals for our current and potential product candidates. ● Conducting successful clinical studies may require the enrollment of large numbers of patients, and suitable patients may be difficult to identify and recruit. ● Delays in the commencement, enrollment and completion of clinical trials could result in increased costs to us and delay or limit our ability to obtain regulatory approval for REQORSA and other current or future product candidates. ● Fast track designation of our products by FDA and designation under any other FDA expedited development program may not actually lead to a faster development or regulatory review or approval process, nor will it assure FDA approval of our product candidates. ● We may not be able to obtain or maintain orphan drug designation or exclusivity for our product candidates. ● A product candidate can fail at any stage of preclinical and clinical development. ● REQORSA®, GPX-002, and any other product candidate we advance through clinical trials may not have favorable results in later clinical trials or receive regulatory approval. Even if we complete the necessary clinical trials, we cannot predict when, or if, we will obtain regulatory approval to commercialize our product candidates, and the approval may be for a narrower indication than we seek. ● Even if we obtain regulatory approval of our current and future product candidates, the products may not gain market acceptance among physicians, patients, hospitals, treatment centers, third-party payors and others in the medical community. ● REQORSA®, GPX-002, and other current or future product candidates may have undesirable side effects that may delay or prevent marketing approval, or, if approval is received, require them to be taken off the market, require them to include safety warnings or otherwise limit their sales. ● If a product liability claim is successfully brought against us for uninsured liabilities, or such claim exceeds our insurance coverage, we could be forced to pay substantial damage awards that could materially harm our business. ● Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer. ● We face risks related to health epidemics and outbreaks, including COVID-19, which could significantly disrupt our preclinical studies and clinical trials. Our business has previously been adversely affected by the coronavirus pandemic which delayed our clinical trials and disrupted our supply chain. A potential resurgence of COVID-19, or any future disease outbreak, epidemic or pandemic, could disrupt our clinical trials and supply chain and materially adversely affect our business and operations. ● We face competition from other biotechnology and pharmaceutical companies, particularly those that are gene therapy companies, and our operating results will suffer if we fail to compete effectively. Risks Related to Regulatory Approval and Marketing of Our Current and Future Product Candidates and Other Legal Compliance Matters ● We cannot provide assurance that REQORSA, GPX-002, or any of our other current or future product candidates will receive regulatory approval, and without regulatory approval we will not be able to market them. ● Even if we obtain regulatory approval for our product candidates, our products will remain subject to regulatory oversight. ● If the FDA does not find the manufacturing facilities of our current or future contract manufacturers acceptable for commercial production, we may not be able to commercialize REQORSA, GPX-002, or any of our other current or future product candidates. ● We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws and other federal and state healthcare laws, and the failure to comply with such laws could result in substantial penalties. Our employees, independent contractors, consultants, principal investigators, CROs, commercial partners and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements. ● Coverage and reimbursement may be limited or unavailable in certain market segments for REQORSA, GPX-002, and our other current or future product candidates, if approved, which could make it difficult for us to sell REQORSA, GPX-002, and our other current or future product candidates profitably. ● Concerns about gene therapy, genetic testing, and genetic research could result in new and/or additional government regulations and requirements that restrict or prohibit the processes we use or delay or prevent the regulatory approval of our current and potential product candidates. ● Healthcare legislative reform measures may have a material adverse effect on our business and results of operations. ● We are subject to a variety of risks associated with international operations which could materially adversely affect our business. ● If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business. Risks Related to Our Dependence on Third Parties ● We may not be successful in establishing and maintaining development and commercialization collaborations, which could adversely affect our ability to develop our current and future product candidates and our financial condition and operating results could be adversely affected. ● We rely, in part, and expect to continue to rely, in part, on third parties to conduct, supervise and monitor our clinical trials, and if these third parties perform in an unsatisfactory manner, it may harm our business. ● We rely, and expect to continue to rely, on third parties to distribute, manufacture and perform release testing for our current and future product candidates and other key materials and if such third parties do not carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approvals for our product candidates. ● We have completed and may in the future complete related party transactions that were not and may not be conducted on an arm’s length basis. ● Disruptions in the global economy and supply chains may have a material adverse effect on our business, financial condition and results of operations. 44 Risks Related to Our Intellectual Property ● If we fail to comply with obligations pursuant to our license agreements, we could lose intellectual property and other rights that are important to our business; if we fail to obtain licenses to advance our research and development that may be required we may be unable to develop the affected product exclusively, on acceptable terms or at all. ● The intellectual property rights we have licensed from MD Anderson and the UP are subject to the rights of the U.S. government. ● If we are unable to protect our intellectual property rights or if our intellectual property rights are inadequate for our technology and product candidates, our competitive position could be harmed. ● Third-party claims of intellectual property infringement may prevent or delay our development and commercialization efforts. ● We may not be successful in obtaining or maintaining necessary rights to product components and processes for our development pipeline through acquisitions and in- licenses. ● Confidentiality agreements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information and may not adequately protect our intellectual property. ● Our reliance on third parties may require us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed. ● We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time-consuming and unsuccessful. ● Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements. ● Issued patents covering our product candidates could be found invalid or unenforceable if challenged in court. ● We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties or that our employees have wrongfully used or disclosed alleged trade secrets of their former employers. ● We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property. ● Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our products. ● We have in the past and may again in the future have trademark applications in the United States and/or certain other countries, and failure to secure these registrations could adversely affect our business; additionally, we may need to enforce our trademark rights against third parties and expend significant resources to enforce such rights against infringement. ● We may not be able to protect our intellectual property rights throughout the world. Risks Related to Employee Matters and Managing Growth ● We have no sales, marketing or distribution experience and we will have to invest significant resources to develop those capabilities or enter into acceptable third-party sales and marketing arrangements. ● We may not be able to manage our business effectively if we are unable to attract and retain key personnel and consultants. ● We may use our financial and human resources to pursue a particular research program or product candidate and fail to capitalize on programs or product candidates that may be more profitable or for which there is a greater likelihood of success. ● If we engage in future acquisitions or strategic partnerships, this may increase our capital requirements, dilute our stockholders, cause us to incur debt or assume contingent liabilities, and subject us to other risks. Risks Related to our Securities ● The market price of our common stock may be highly volatile, and you may lose all or part of your investment. ● An active, liquid and orderly market for our common stock may not be sustained, and you may not be able to sell your common stock. ● We are currently listed on The Nasdaq Capital Market. If we are unable to maintain listing of our securities on Nasdaq or any stock exchange, our stock price could be adversely affected and the liquidity of our stock and our ability to obtain financing could be impaired and it may be more difficult for our stockholders to sell their securities. ● Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and stock price. ● Failure to maintain effective internal control over our financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002, as amended (“Sarbanes- Oxley Act”) could cause our financial reports to be inaccurate. ● We have no intention of declaring dividends in the foreseeable future. ● We will likely incur increased costs and devote additional management time to public company reporting and compliance obligations as a result of exiting “emerging growth company” status. ● Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall. ● Future sales and issuances of our securities could result in additional dilution of the percentage ownership of our stockholders and could cause our share price to fall. ● If securities or industry analysts do not publish research or reports about us, or if they adversely change their recommendations regarding our common stock, then our stock price and trading volume could decline. ● Certain provisions in our organizational documents could enable our board of directors to prevent or delay a change of control. ● Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws contain an exclusive forum provision with respect to certain actions which may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable and discourage lawsuits against us or our current or former directors or officers and/or stockholders in such capacity. General Risk Factors ● Obligations associated with being a public company in the United States are expensive and time-consuming, and our management will be required to devote substantial time to compliance matters. ● Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses. ● We may be at risk of securities class action litigation. 45 Item 1A. Risk Factors. An investment in our common stock involves a high degree of risk. You should carefully consider the following risk factors and the other information in this Annual Report on Form 10-K before investing in our common stock. Our business and results of operations could be seriously harmed by any of the following risks. The risks set out below are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results. If any of the following events occur, our business, financial condition and results of operations could be materially adversely affected. In such case, the value and trading price of our common stock could decline, and you may lose all or part of your investment. Risks Related to Our Operations and Need for Additional Capital We will require substantial additional funding, which may not be available to us on acceptable terms, or at all, and, if not so available, may require us to delay, limit, reduce or cease our operations. We are using the proceeds from our sales of securities to advance REQORSA through clinical development, and to advance our other preclinical development programs as well as for other corporate purposes. Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is expensive. We will require substantial additional future capital to complete clinical development and commercialize REQORSA and for preclinical and clinical development and commercialization of our gene therapy for diabetes, GPX-002, and our other product candidates. If the FDA requires that we perform additional preclinical studies or clinical trials beyond what we currently anticipate, our expenses will further increase beyond what we currently expect and the anticipated timing of any potential approval of REQORSA, GPX-002, and our other current or future product candidates would likely be delayed. Furthermore, there can be no assurance that the costs to obtain regulatory approval of these product candidates will not increase. We will continue to require substantial additional capital to continue our preclinical and clinical development and commercialization readiness activities. Because successful development of our current and potential product candidates is uncertain, we are unable to estimate the actual amount of funding we will require to complete research and development and commercialize our current and future product candidates. The amount and timing of our future funding requirements will depend on many factors, including, but not limited to: ● the progress, costs, results and timing of our preclinical development and clinical trials for REQORSA, GPX-002, and other current or future product candidates; ● the outcome, costs and timing of seeking and obtaining FDA and any other regulatory approvals; ● the ability of third parties to deliver materials and provide services for us; ● the costs associated with securing and establishing commercialization and manufacturing capabilities; ● market acceptance of our current and future product candidates; ● the costs of acquiring, licensing or investing in businesses, products, product candidates and technologies; ● our ability to obtain, maintain, expand and enforce intellectual property rights for our products and product candidates, including the amount and timing of any payments we may be required to make, or that we may receive, in connection with the licensing, filing, prosecution, defense and enforcement of any patents or other intellectual property rights; ● our need and ability to hire additional management and scientific and medical personnel; ● the effect of competing drug candidates and new product approvals; ● our need to implement additional internal systems and infrastructure, including financial and reporting systems; and ● the economic and other terms, timing of and success of our existing licensing arrangements and any collaboration, licensing or other arrangements into which we may enter in the future. Some of these factors are outside of our control. Although we expect that our existing cash will be sufficient to fund our current operations and planned clinical trial activities into the third quarter of 2024, this period could be shortened if there are any significant increases in planned spending on current or additional development programs or more rapid progress of these development programs than anticipated. Furthermore, we believe that our existing capital will not be sufficient to enable us to complete the development and commercialization of REQORSA, GPX-002, and our other current or future product candidates. Accordingly, we expect that we will need to raise additional funds in the future. We have raised and may continue to raise capital through a variety of sources that may be available to us. On March 1, 2023, we completed a registered direct offering, in which we sold to an accredited healthcare-focused institutional investor an aggregate of (i) 95,239 shares of our common stock and (ii) warrants to purchase up to 95,239 shares of our common stock, at a combined offering price of $42.00 per share of common stock and accompanying warrant, for net proceeds of approximately $3.6 million. On July 21, 2023, we completed a registered direct offering priced at the market under Nasdaq rules, in which we sold to accredited healthcare-focused institutional investors an aggregate of (i) 185,644 shares of our common stock, and (ii) warrants to purchase up to 185,644 shares of our common stock, at a combined offering price of $40.40 per share of common stock and accompanying warrant, for net proceeds of approximately $6.7 million. On December 13, 2023, we entered into an At The Market (“ATM”) Offering Agreement (the “Agreement”) with H.C. Wainwright & Co., LLC, serving as agent (“H.C. Wainwright” or the “Agent”) with respect to an at-the-market offering program under which we may offer and sell through the Agent, from time to time at our sole discretion, up to such number or dollar amount of shares of our common stock (the “Shares”) as registered on the prospectus supplement covering the ATM offering, as may be amended or supplemented from time to time. We have agreed to pay the Agent a commission equal to three percent (3%) of the gross sales proceeds of any Shares sold through the Agent under the Agreement, and also have provided the Agent with customary indemnification and contribution rights. As of December 31, 2023 we had not sold any Shares through the Agent under the Agreement. From January 1, 2024 through the date of filing of this Annual Report on Form 10-K, we have sold 158,474 Shares for net proceeds to us totaling $881,946 through the Agent under the Agreement. On March 21, 2024, we completed a registered direct offering, in which we sold to an institutional investor an aggregate of (i) 165,000 shares of our common stock, (ii) March 2024 Pre-Funded Warrants exercisable for up to an aggregate of 1,377,112 shares of our common stock, and (iii) March 2024 Common Warrants exercisable for up to an aggregate of 1,542,112 shares of our common stock, at a combined offering price of $4.215 per share of common stock (or $4.2149 per March 2024 Pre-Funded Warrant in lieu thereof) and accompanying March 2024 Common Warrant, for net proceeds of approximately $5.8 million. In connection with the March 2024 registered direct offering, we amended certain existing warrants to reduce the exercise price and extend the term thereof as discussed above in Part I, Item 1 of this Annual Report in the section captioned Recent Developments – March 2024 Registered Direct Offering”. 46 We may seek additional funding through a combination of equity offerings, drawdowns on our ATM pursuant to our At The Market Offering Agreement with H.C. Wainwright as Agent, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements, some of which may require us to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us. Additional funding may not be available to us on acceptable terms, if at all. In addition, the terms of any financing may adversely affect the holdings or the rights of our stockholders. Any new equity securities we issue could have rights, preferences, and privileges superior to those of holders of our existing capital stock. In addition, the issuance of additional shares by us may cause the market price of our shares to decline and result in dilution to our stockholders. Any debt financing secured by us in the future could involve restrictive covenants relating to our capital-raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities. If we are unable to obtain funding on a timely basis, we may be required to significantly curtail one or more of our preclinical or clinical development programs, our ability to continue to support our business growth and to respond to business challenges could be significantly limited, and we may be required to curtail or cease operations. Accordingly, our business may fail, in which case you would lose the entire amount of your investment in our securities. Our recurring losses from operations have raised substantial doubt regarding our ability to continue as a going concern. We have recognized recurring losses, and as of December 31, 2023, had an accumulated deficit of approximately $133.9 million. We anticipate operating losses to continue for the foreseeable future due to, among other things expenses related to ongoing activities to research, develop and commercialize our product candidates. We expect the cash and cash equivalents of approximately $6.7 million at December 31, 2023 to be insufficient to meet our operating and capital requirements at least 12 months from the filing of this Annual Report on Form 10-K. Our forecast of the period of time through which our current financial resources will be adequate to support our operations and the costs to support our general and administrative and research and development activities are forward-looking statements and involve risks and uncertainties. The financial statements do not include any adjustments that might be necessary should we be unable to continue as a going concern. As further described below, our ability to continue as a going concern is dependent on our ability to raise additional working capital through public or private equity or debt financings or other sources, which may include collaborations with third parties as well as disciplined cash spending. Should we be unable to raise sufficient additional capital, we may be required to undertake cost-cutting measures including delaying or discontinuing certain clinical activities. The sale of equity and convertible debt securities may result in dilution to our stockholders and certain of those securities may have rights senior to those of our common stock. If we raise additional funds through the issuance of preferred stock, convertible debt securities or other debt financing, these securities or other debt could contain covenants that would restrict our operations. Any other third-party funding arrangement could require us to relinquish valuable rights. The source, timing and availability of any future financing will depend principally upon market conditions, and, more specifically, on the progress of our clinical development programs. Funding may not be available when needed, at all, or on terms acceptable to us. Lack of necessary funds may require us, among other things, to delay, scale back or eliminate some or all of our planned clinical trials. These factors among others create a substantial doubt about our ability to continue as a going concern. We have never been profitable, we have no products approved for commercial sale, and to date we have not generated any revenue from product sales. As a result, our ability to reduce our losses and reach profitability is unproven, and we may never achieve or sustain profitability. We have never been profitable and do not expect to be profitable in the foreseeable future. We have not yet submitted any drug candidates for approval by regulatory authorities in the United States or elsewhere. From our inception on April 1, 2009, to December 31, 2023, we incurred an accumulated deficit of approximately $133.9 million. We incurred net losses of approximately $31.0 million and approximately $23.7 million for the years ended December 31, 2023 and 2022, respectively. To date, we have devoted most of our financial resources to our corporate overhead and research and development, including our preclinical development activities, manufacturing processes and clinical trials. We have not generated any revenues from product sales. We expect to continue to incur losses for the foreseeable future, and we expect these losses to increase as we continue our development of, and seek regulatory approvals for, our current and potential product candidates, prepare for and begin the commercialization of any approved products, and add infrastructure and personnel to support our continuing product development efforts. We anticipate that any such losses could be significant for the next several years. If REQORSA, GPX-002, or any of our other current or future product candidates fail in clinical trials or does not gain regulatory approval, or if our drug candidates do not achieve market acceptance, we may never become profitable. These net losses and negative cash flows have had, and will continue to have, an adverse effect on our stockholders’ equity and working capital. Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses or if, or when, we will be able to achieve profitability. In addition, our expenses could increase if we are required by the FDA to perform studies or trials in addition to those currently expected, or if there are any delays in completing our clinical trials or the development of any of our drug candidates. The amount of future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenues. We have a limited operating history and we expect a number of factors to cause our operating results to fluctuate on an annual basis, which may make it difficult to predict our future performance. We are a clinical stage company with a limited operating history. Our operations to date have been limited to conducting clinical and preclinical research and development. We have not yet obtained any regulatory approvals for any of our drug candidates. Consequently, any predictions made about our future success or viability may not be accurate. Our operating results are expected to significantly fluctuate from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include: ● any delays in regulatory review and approval (assuming that our data support approval) of our current and future product candidates in clinical development, including our ability to receive approval from the FDA for REQORSA or GPX-002; ● delays in the commencement, enrollment and timing of clinical trials; ● the success of our current and future product candidates through all phases of preclinical and clinical development, including the ability of our third-party suppliers or manufacturers to supply or manufacture our products on a timely, consistent basis in a manner sufficient and appropriate as is commensurate to meet our clinical trial timing, courses of treatment, and other requisite fulfillment considerations necessary to adequately advance our development programs; ● potential side effects of our current and future product candidates that could delay or prevent approval or cause an approved drug to be taken off the market; ● our ability to obtain additional funding to develop our current and future product candidates; ● our identification and development of additional drug candidates beyond REQORSA, GPX-002, and our other current product candidates; ● competition from existing products or new products that continue to emerge; ● the ability of patients or healthcare providers to obtain coverage or sufficient reimbursement for our products; ● our ability to adhere to clinical trial requirements directly or with third parties such as contract research organizations ("CROs"); ● our dependency on third-party suppliers or manufacturers to manufacture our key ingredients and/or raw materials, products and/or product components and successfully carry out a sustainable, reproducible and scalable manufacturing process in accordance with specifications or applicable regulations; ● our ability to establish or maintain collaborations, licensing, sponsored research or other arrangements, particularly with MD Anderson and UP and otherwise relating to REQORSA, and GPX-002; ● our ability to defend against any challenges to our intellectual property including claims of patent infringement; ● our ability to enforce our intellectual property rights against potential competitors; ● our ability to secure additional intellectual property protection for our product candidates and associated technologies as may be required or desirable as the development of the product candidates progresses; ● our ability to attract and retain key personnel to manage our business effectively; and ● potential product liability claims. 47 Our ability to utilize our net operating loss carryforwards may be limited, resulting in income taxes sooner than currently anticipated. As of December 31, 2023, we had federal net operating loss carryforwards (“NOLs”) of approximately $80.5 million for federal income tax purposes of which approximately $1.3 million will begin to expire in 2030 and approximately $79.2 million can be carried forward indefinitely. These NOLs may be used to offset future taxable income, to the extent we generate any taxable income, and thereby reduce or eliminate our future federal income taxes otherwise payable. Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), imposes limitations on a corporation’s ability to utilize NOLs if it experiences an ownership change as defined in Section 382. In general terms, an ownership change may result from transactions increasing the ownership of certain stockholders in the stock of a corporation by more than 50% over a three-year period. In the event that an ownership change has occurred, or were to occur, utilization of our NOLs would be subject to an annual limitation under Section 382 determined by multiplying the value of our stock at the time of the ownership change by the applicable long-term tax-exempt rate as defined in the Code. Any unused annual limitation may be carried over to later years. We may be found to have experienced an ownership change under Section 382 as a result of events in the past or the issuance of shares of common stock in the future. If so, the use of our NOLs, or a portion thereof, against our future taxable income may be subject to an annual limitation under Section 382, which may result in expiration of a portion of our NOLs before utilization. The utilization of our NOLs may also be limited under state laws. In addition, under the 2017 Tax Cuts and Jobs Act (the “TCJA”), tax losses generated in taxable years beginning after December 31, 2017 may be utilized to offset no more than 80% of taxable income annually. This change may require us to pay federal income taxes in future years despite generating a loss for federal income tax purposes. There is also a risk that due to regulatory changes, such as suspensions on the use of NOLs, or other unforeseen reasons, our existing NOLs could expire or otherwise be unavailable to offset future income tax liabilities. For these reasons, we may not be able to realize a tax benefit from the use of our NOLs, whether or not we attain profitability. Risks Related to Development and Commercialization of Our Current and Future Product Candidates Our success depends greatly on the success of our development of REQORSA for the treatment of NSCLC and SCLC, and our other product candidates, including GPX-002 for the treatment of diabetes. At this time, we are actively pursuing the development of REQORSA for NSCLC through our Acclaim-1 and Acclaim-2 clinical trials and for SCLC through our Acclaim-3 clinical trial, which are all currently enrolling patients. We are also pursuing the development of preclinical gene therapy GPX-002 for Type 1 and Type 2 diabetes, as well as earlier discovery programs. In particular, we are dependent on the success of REQORSA and GPX-002. We cannot provide you any assurance that we will be able to successfully advance REQORSA, GPX-002 or any of our other current or future product candidates through the development process, or that any development problems we experience in the future will not cause significant delays or unanticipated costs, or that such development problems can be solved. We may also experience delays in the development of a sustainable, reproducible and scalable manufacturing process or transferring that process to commercial partners, or developing or validating product release assays in a timely manner, which may prevent us from completing our clinical trials or commercializing our products on a timely or profitable basis, if at all. Immunotherapy, gene therapy and biopharmaceutical product development are highly speculative undertakings and involve a substantial degree of uncertainty. Because REQORSA, GPX-002 and our other current product candidates are based upon novel technology, it is difficult to predict whether, either as stand-alone therapies or in combination with other drugs, they will show consistently favorable results and to predict the time and cost of their development and of subsequently obtaining regulatory approval. We believe only a few gene therapy products have been approved in the United States or Europe. We have found it difficult to enroll patients in our clinical studies in the past, have experienced certain difficulties in enrolling patients in our current trials and may continue to find it difficult in the future, which could delay or prevent clinical studies of REQORSA or other current or future product candidates. We may encounter other delays in our preclinical or clinical studies, or we may fail to demonstrate safety and efficacy to the satisfaction of FDA and other regulatory authorities. We may not be successful in our efforts to identify or discover additional product candidates, or to develop product candidates that we have identified. In addition, the clinical trial requirements of the FDA, the European Commission, the European Medicines Agency (“EMA”), the competent authorities of the Member States of the European Union (“EU”) and other regulatory authorities and the criteria these regulators use to determine the safety and efficacy of a product candidate vary substantially according to the type, complexity, novelty and intended use and market of such product candidates. The regulatory approval process for novel product candidates such as ours can be more expensive and take longer than for other, better known or more extensively studied product candidates. Even if we are successful in developing product candidates, it is difficult to determine how long it will take or how much it will cost to obtain regulatory approvals for these product candidates in either the United States or the EU, or how long it will take to commercialize any other products for which we receive marketing approval. In addition, any future marketing authorization granted by the European Commission may not be indicative of what the FDA may require for approval and vice versa. 48 If we are unable to secure contract manufacturers with capabilities to produce the products that we require, we could experience delays in conducting our planned clinical trials. Manufacturing REQORSA involves several manufacturing steps. Historically, part of our manufacturing process was conducted in manufacturing facilities at MD Anderson. We have transferred all of the steps of our manufacturing process to CDMOs and scaled-up clinical production in order to supply our Acclaim-1, Acclaim-2 and Acclaim- 3 clinical trials. We also are preparing for commercial readiness for REQORSA through the development of an integrated supply chain network of manufacturing vendors and continue to work to identify cutting edge manufacturing technologies to optimize manufacturing processes and shelf life. With the advancement of the development of GPX-002, we also are working to optimize the manufacture of this product candidate and to source high quality and integrated vendors capable of producing it in accordance with GMP. Although we have contracted with CDMOs to produce our products, no assurance can be given that such CDMOs will be able to continue to produce the products that we require. In addition, the tremendous growth in the gene therapy sector has created increasing demand for the services of CDMOs with gene therapy capabilities which may impact our ability to schedule production runs of our products or product components to meet our needs on a timely basis. Furthermore, manufacturing gene-based therapies is complex and highly regulated and a CDMO with which we have contracted may fail to produce our products or product components timely or in accordance with our specifications or applicable regulations. We have experienced a variety of these challenges to varying degrees in connection with performance by our CDMOs, which have resulted in delays in our Acclaim-1, Acclaim-2 and Acclaim-3 clinical trials in the past. Changing our current or future contract manufacturers may be difficult and could be costly, which could result in our inability to manufacture our clinical product candidates and a delay in the development of our clinical product candidate. Further, in order to maintain our development timelines, any changes to, or the addition of a new, third-party contract manufacturers may result in our incurring higher costs to manufacture our clinical product candidates. Any delay in the availability of product supply or product component supply could result in a delay in our clinical trials, including our Acclaim-1, Acclaim-2 and Acclaim-3 clinical trials as well as the commencement of clinical trials for GPX-002. Negative public opinion and increased regulatory scrutiny of gene therapy and genetic research may damage public perception of our current and potential product candidates or adversely affect our ability to conduct our business or obtain regulatory approvals for our current and potential product candidates. Public perception may be influenced by claims that gene therapy is unsafe, and gene therapy may not gain the acceptance of the public or the medical community. In particular, our success will depend upon physicians prescribing treatments that involve the use of our product candidates in lieu of, or in addition to, existing treatments with which they are already familiar and for which greater clinical data may be available. More restrictive government regulations or negative public opinion would have a negative effect on our business or financial condition and may delay or impair the development and commercialization of our current and potential product candidates or demand for any products we may develop. Adverse events in our clinical trials, even if not ultimately attributable to our current and potential product candidates, and the resulting publicity could lead to increased governmental regulation, unfavorable public perception, potential regulatory delays in the testing or approval of our potential product candidates, stricter labeling requirements for those product candidates that are approved and a decrease in demand for any such product candidates. Concern about the environmental spread of our product, whether real or anticipated, could also hinder the commercialization of our products. Prior to receiving REQORSA in our Acclaim-1 clinical trial, patients are required to undergo genetic screening to detect EGFR mutations. Genetic testing has raised concerns regarding the appropriate utilization and the confidentiality of information provided by genetic testing. Genetic tests for assessing a person’s likelihood of developing a chronic disease have focused public attention on the need to protect the privacy of genetic information. Genetic testing information is also subject to significant restrictions under both federal and state law. For example, concerns have been expressed that insurance carriers and employers may use these tests to discriminate on the basis of genetic information, resulting in barriers to the acceptance of genetic tests by consumers. This could lead to governmental authorities restricting genetic testing or calling for limits on or regulating the use of genetic testing, particularly for diseases for which there is no known cure. Any of the foregoing could decrease demand for REQORSA or our other product candidates. Conducting successful clinical studies may require the enrollment of large numbers of patients, and suitable patients may be difficult to identify and recruit. Patient enrollment in clinical trials and completion of patient participation and follow-up depends on many factors, including the size of the patient population; the nature of the trial protocol; the attractiveness of, or the discomforts and risks associated with, the treatments received by enrolled subjects; the availability of appropriate clinical trial investigators; support staff; and proximity of patients to clinical sites; ability to comply with the eligibility and exclusion criteria for participation in the clinical trial; and patient compliance. For example, patients may be discouraged from enrolling in our clinical trials if the trial protocol requires them to undergo extensive post-treatment procedures or follow-up to assess the safety and effectiveness of our product candidates or if they determine that the treatments received under the trial protocols are not attractive or involve unacceptable risks or discomforts. Patients may also not participate in our clinical trials if they choose to participate in contemporaneous clinical trials of competitive products. In addition, our ability to successfully initiate, enroll and complete clinical trials in any foreign country is subject to numerous risks of conducting business in foreign countries, including: ● difficulty in establishing or managing relationships with CROs and physicians; ● different standards for the conduct of clinical trials; ● our inability to locate qualified local consultants, physicians and partners; and ● the potential burden of complying with a variety of foreign laws, medical standards and regulatory requirements, including the regulation of pharmaceutical and biotechnology products and treatments. If we have difficulty enrolling a sufficient number of patients to conduct our clinical trials as planned, we may need to delay, limit or terminate ongoing or planned clinical trials, any of which would have an adverse effect on our business. 49 Delays in the commencement, enrollment and completion of clinical trials could result in increased costs to us and delay or limit our ability to obtain regulatory approval for REQORSA and other current or future product candidates. Clinical development is very expensive and can take many years. Delays in the commencement, enrollment and/or completion of our Acclaim-1, Acclaim-2 and Acclaim-3 clinical trials or any future clinical trials could increase our product development costs or delay or limit the regulatory approval of REQORSA or other product candidates. We have experienced delays in opening our clinical sites for our Acclaim-1 and Acclaim-2 trials in the past; for example, during the COVID-19 pandemic there was a delay due to a back-log in protocol review at the clinical trial sites. We do not know and cannot predict whether future trials or studies of other current or future product candidates, including later stages of our Acclaim trials, and any for GPX-002, will begin as planned, if at all, and we do not know and cannot predict whether our Acclaim-1, Acclaim-2 and Acclaim-3 clinical trials or any future trials or studies of other current or future product candidates will be completed on schedule, if at all. The start or end of a clinical study may be delayed or halted due to regulatory requirements, changes in the proposed regulatory approval pathway for a drug candidate, manufacturing challenges, including delays or shortages in available raw materials required to manufacture the drug product, 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, such as mutation of the EGFR which is required for the Acclaim-1 trial and is present in a minority of NSCLC patients. Rates of patient enrollment are affected by many factors, including the size of the patient population, the eligibility criteria for the clinical trial, which include the age and condition of the patients and the stage and severity of disease, the nature of the protocol, the proximity of patients to clinical sites and the availability of effective treatments and/or availability of other investigational treatment options for the relevant disease. We have initiated our Acclaim-1, Acclaim-2 and Acclaim-3 clinical trials pursuant to an existing IND. We have previously filed with the FDA amendments to our IND consisting of an updated chemistry, manufacturing and controls section, and the protocol for the respective clinical trial. We cannot be sure that issues will not arise in the future in connection with potential subsequent amendments or otherwise that might result in the FDA imposing a clinical hold which could result in the delay of any of these clinical trials. For GPX-002 we have not yet filed an IND and cannot predict all of the challenges and issues that may arise in connection with the preparation and filing of an IND, or whether this IND will be filed at all. Fast track designation of our products by FDA and designation under any other FDA expedited development program may not actually lead to a faster development or regulatory review or approval process, nor will it assure FDA approval of our product candidates. REQORSA has received three fast track designations from the FDA. We may in the future seek additional fast track designations for our products and/or request breakthrough therapy designation, accelerated approval or priority review of applications for approval. FDA has broad discretion whether or not to grant these designations and requests, so even if we believe a particular product candidate is eligible for these designations, we cannot assure you that the FDA will grant them. Even with fast track designation and other FDA expedited development programs, we may not experience a faster development process, review or approval compared to conventional FDA procedures. The FDA may withdraw fast track designation and other expedited program designations if it believes that the requirements of the program are no longer met. We may not be able to obtain or maintain orphan drug designation or exclusivity for our product candidates. In August 2023, the FDA granted Orphan Drug Designation to REQORSA for the treatment of SCLC. Upon receipt of regulatory approval, orphan drug status will provide us with seven years of market exclusivity in the United States under the Orphan Drug Act. We may seek other orphan drug designations in the future in the United States and in the European Union for our product candidates. However, there is no guarantee that the FDA will grant orphan drug designation for any of our other drug candidates for any future indication, which would make us ineligible for the additional exclusivity and other benefits of orphan drug designation for those other drug candidates in the future. Moreover, there can be no assurance that another company also holding orphan drug designation for the same indication or which may receive orphan drug designation in the future will not receive approval prior to us, in which case our competitor would have the benefit of the seven years of market exclusivity, and we would be unable to commercialize our product for the same indication until the expiration of such seven-year period. Even if we are the first to obtain approval for the orphan drug indication, there are circumstances under which a competing product may be approved for the same indication during our seven-year period of exclusivity. Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making a drug available in the Unites States for this type of disease or condition will be recovered from sales of the product. Orphan drug designation must be requested before submitting an NDA or BLA. After the FDA grants orphan drug designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan designation does not convey any advantage in or shorten the duration of regulatory review and approval process. In addition to the potential period of exclusivity, orphan designation makes a company eligible for grant funding of up to $400,000 per year for four years to defray costs of clinical trial expenses, tax credits for clinical research expenses and potential exemption from the FDA application user fee. If a product that has orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan drug exclusivity, which means the FDA may not approve any other applications to market the same drug for the same indication for seven years, except in limited circumstances, such as (i) the drug’s orphan designation is revoked; (ii) its marketing approval is withdrawn; (iii) the orphan exclusivity holder consents to the approval of another applicant’s product; (iv) the orphan exclusivity holder is unable to assure the availability of a sufficient quantity of drug; or (v) a showing of clinical superiority to the product with orphan exclusivity by a competitor product. If a drug designated as an orphan product receives marketing approval for an indication broader than what is designated, it may not be entitled to orphan drug exclusivity. There can be no assurance that we will receive orphan drug designation for any of our drug candidates for any additional indications, if we elect to seek such designation. Even if orphan designation is granted it may be withdrawn by the FDA for non-compliance with regulations. 50 A product candidate can fail at any stage of preclinical and clinical development. The historical failure rate for product candidates is high due to scientific feasibility, safety, efficacy, 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, but not limited to, a belief that subjects participating in such trials are being exposed to unacceptable health risks or adverse side effects, or other adverse initial experiences or findings. 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: ● inability to obtain sufficient funds required for clinical development; ● inability to reach agreements on acceptable terms with current or prospective vendors, CROs and trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different vendors, CROs and trial sites; ● negative or inconclusive results from our clinical studies or the clinical studies 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 side effects experienced by subjects in our clinical trials or by individuals using drugs similar to our current and future product candidates; ● conditions imposed by the FDA or comparable foreign authorities regarding the scope or design of our clinical trials; ● unexpected results from preclinical testing and development; ● inability or delays in enrolling research subjects in clinical trials; ● high drop-out rates and high fail rates of research subjects; ● inadequate supply or quality of product candidate components or materials or other supplies necessary for the conduct of preclinical or clinical testing; ● greater than anticipated clinical trial costs; ● poor effectiveness of our current and potential product candidates during clinical trials; or ● unfavorable FDA or other regulatory agency inspection and review of a clinical trial site or vendor. REQORSA®, GPX-002, and any other product candidate we advance through clinical trials may not have favorable results in later clinical trials or receive regulatory approval. Even if we complete the necessary clinical trials, we cannot predict when, or if, we will obtain regulatory approval to commercialize our product candidates, and the approval may be for a narrower indication than we seek. Clinical failure can occur at any stage of our clinical development. Clinical trials may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical trials or nonclinical studies. In addition, data obtained from trials and studies are susceptible to varying interpretations, and regulators may not interpret our data as favorably as we do, which may delay, limit or prevent regulatory approval. Additionally, our partners, clients, other vendors, and/or other stakeholders may not agree with our interpretation(s) of data obtained from our clinical trials, which could potentially cause a variety of issues, including, but not limited to, delays, the necessity for additional studies and analyses, dependence on third-party validation, and/or other unforeseen challenges. Success in preclinical studies and early clinical trials does not ensure that subsequent clinical trials will generate the same or similar results or otherwise provide adequate data to demonstrate the efficacy and safety of a product candidate. Later-stage clinical trials could differ in significant ways from early-stage clinical trials, including changes to inclusion and exclusion criteria, efficacy endpoints, dosing regimen and statistical design. For example, the small number of patients in our completed Phase 1 Monotherapy clinical trial of REQORSA and the Phase 1/2 Combination Tarceva trial may make the results of these trials less predictive of the outcome of later clinical trials. In addition, although we observed encouraging clinical activity in the Phase 1 Monotherapy and Phase 1/2 Combination Tarceva trial, the primary objectives of the Phase 1 Monotherapy Trial and the Phase 1 portion of the Phase 1/2 Combination Tarceva trial were safety and MTD and not to demonstrate efficacy. The assessments of clinical activity from these clinical trials, some of which were not pre-specified, may not be predictive of the results of later clinical trials of REQORSA. Furthermore, safety events may be observed in later trials that alter the anticipated risk-benefit profiles of REQORSA or other product candidates. In addition, the design of a clinical trial can determine whether its results will support approval of a product and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. We may be unable to design and execute a clinical trial to support regulatory approval. Further, clinical trials of potential products often reveal that it is not practical or feasible to continue development efforts. We do not know whether any clinical trials we conduct will demonstrate the consistent or adequate efficacy and safety that would be required to obtain regulatory approval and market any products. If REQORSA, GPX-002 or other current or future product candidates are found to be unsafe or lack efficacy, we will not be able to obtain regulatory approval for it and our business would be harmed. If we are unable to bring REQORSA, GPX-002 or other product candidates to market, or acquire other products that are on the market or can be developed, our ability to create stockholder value will be limited. Regulatory authorities also may approve a product candidate for more limited indications than requested, or they may impose significant limitations in the form of narrow indications. These regulatory authorities may require warnings or precautions with respect to conditions of use or they may grant approval subject to the performance of costly post- marketing clinical trials. In addition, regulatory authorities may not approve the labeling claims or allow the promotional claims that are necessary or desirable for the successful commercialization of our product candidates. Any of the foregoing scenarios could materially harm the commercial prospects for our product candidates and materially and adversely affect our business, financial condition, results of operations and prospects. 51 Even if we obtain regulatory approval of our current and future product candidates, the products may not gain market acceptance among physicians, patients, hospitals, treatment centers, third-party payors and others in the medical community. Ethical, social and legal concerns about gene therapy and genetic research could result in additional regulations restricting or prohibiting the products and processes we may use. Even with the requisite approvals, the commercial success of REQORSA, GPX-002 and any of our other current or future product candidates will depend in part on the medical community, patients, and third-party payors accepting gene therapy products in general, and our current and future product candidates in particular, as medically useful, cost-effective and safe. Any product that we bring to the market may not gain market acceptance by physicians, patients, hospitals, treatment centers, third-party payors and others in the medical community. If these products do not achieve an adequate level of acceptance, we may not generate significant product revenue and may not become profitable. The degree of market acceptance of these product candidates, if approved for commercial sale, will depend on a number of factors, including: ● the clinical indications for which our current and potential product candidates are approved; ● physicians, hospitals, treatment centers and patients considering our product candidates as a safe and effective treatment; ● the potential and perceived advantages of our product candidates over alternative treatments; ● the prevalence and severity of any side effects; ● product labeling or product insert requirements of the FDA or other regulatory authorities; ● limitations or warnings contained in the labeling approved by the FDA; ● the timing of market introduction of our product candidates as well as competitive products; ● the cost of treatment – both in absolute terms and in relation to alternative treatments; ● the availability of coverage, reimbursement and pricing by third-party payors and government authorities and the adequacy thereof; ● the willingness of patients to pay out-of-pocket in the absence of coverage by third-party payors, including government authorities; ● the willingness, ability and availability of healthcare providers that can comply with the transportation, handling, and temperature-controlled storage requirements associated with our product candidates; ● relative convenience and ease of administration, including as compared to alternative treatments and competitive therapies; and ● the effectiveness of our sales and marketing efforts, which are subject to various limitations under applicable law. Our efforts to educate the medical community and third-party payors about the benefits of our product candidates may require significant resources and may never be successful. REQORSA®, GPX-002, and other current or future product candidates may have undesirable side effects that may delay or prevent marketing approval, or, if approval is received, require them to be taken off the market, require them to include safety warnings or otherwise limit their sales. Undesirable side effects for REQORSA, GPX-002, or any of our other current or future product candidates could arise either during clinical development or, if approved, after the approved product has been marketed. A showing that REQORSA, GPX-002, or any of our other current or future product candidates cause undesirable or unacceptable side effects could interrupt, delay or halt clinical trials and result in the failure to obtain or suspension or termination of marketing approval from the FDA and other regulatory authorities, or result in marketing approval from the FDA and other regulatory authorities only with restrictive label warnings. If REQORSA, GPX-002, or any of our other current or future product candidates receives marketing approval and we or others later identify undesirable or unacceptable side effects caused by such products: ● regulatory authorities may require the addition of labeling statements, specific warnings, a contraindication or field alerts to physicians and pharmacies; ● we may be required to change instructions regarding the way the product is administered, conduct additional clinical trials or change the labeling of the product; ● we may be subject to limitations on how we may promote the product; ● sales of the product may decrease significantly; ● regulatory authorities may require us to take our approved product off the market; ● we may be subject to litigation or product liability claims; and ● our reputation may suffer. Any of these events could prevent us or our potential future collaborators from achieving or maintaining market acceptance of our products or could substantially increase commercialization costs and expenses, which in turn could delay or prevent us from generating revenues from the sale of our products. 52 If a product liability claim is successfully brought against us for uninsured liabilities, or such claim exceeds our insurance coverage, we could be forced to pay substantial damage awards that could materially harm our business. The use of any of our existing or future product candidates in clinical trials and the sale of any approved pharmaceutical products may expose us to significant product liability claims. We currently carry product liability insurance relating to our clinical trials only. Such insurance coverage may not protect us against any or all of the product liability claims that may be brought against us in the future. We may not be able to acquire or maintain adequate product liability insurance coverage at a commercially reasonable cost or in sufficient amounts or scope to protect us against potential losses. In the event a product liability claim is brought against us, we may be required to pay legal and other expenses to defend the claim, as well as uncovered damage awards resulting from a claim brought successfully against us. In the event our product candidate is approved for sale by the FDA or other regulatory agency and commercialized, we may need to substantially increase the amount of our product liability coverage. Defending any product liability claim or claims could require us to expend significant financial and managerial resources, which could have an adverse effect on our business. Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer. In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary business information and that of our suppliers and business partners, as well as personally identifiable information of clinical trial participants and employees. Similarly, our CROs, contractors and consultants possess certain of our sensitive data. The secure maintenance of this information is critical to our operations and business strategy. Despite the implementation of security measures, our internal computer systems and those of our CROs, CMOs, and other contractors and consultants are vulnerable to damage from cyberattacks, malicious intrusion, computer viruses, unauthorized access, loss of data privacy, natural disasters, terrorism, war and telecommunication, electrical failures or other significant disruption. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our drug development programs and commercialization efforts. For example, the loss of clinical study data from completed or ongoing clinical studies for any of our drug candidates could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of or damage to our data or applications or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development or commercialization of our drug candidates could be delayed. While we have not experienced any such event to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our independent drug development programs. For example, the loss of clinical trial data from ongoing or future clinical trials for any of our product candidates could result in delays in regulatory approval efforts and significantly increase costs to recover or reproduce the data. Our information security systems are also subject to laws and regulations requiring that we take measures to protect the privacy and security of certain information we gather and use in our business. For example, HIPAA and its implementing regulations impose, among other requirements, certain regulatory and contractual requirements regarding the privacy and security of personal health information. In addition to HIPAA, numerous other federal, state, and international laws, including, without limitation, state security breach notification laws, state health information privacy laws and federal and state consumer protection laws, govern the collection, use, disclosure and storage of personal information. To the extent that any disruption or security breach were to result in a loss of or damage to data or applications, or inappropriate disclosure of confidential or proprietary information or personal health information, we could incur substantial liability, our reputation would be damaged, and the further development of our product candidates could be delayed. We face risks related to health epidemics and outbreaks, including COVID-19, which could significantly disrupt our preclinical studies and clinical trials. Our business has previously been adversely affected by the coronavirus pandemic which delayed our clinical trials and disrupted our supply chain. A potential resurgence of COVID-19, or any future disease outbreak, epidemic or pandemic, could disrupt our clinical trials and supply chain and materially adversely affect our business and operations. Disease outbreaks, epidemics and pandemics, including COVID-19, in regions where we have concentrations of clinical trial sites and other business operations, could adversely affect our business, including by causing significant disruptions in our operations and/or in the operations of manufacturers and CROs upon whom we rely. Disease outbreaks, epidemics and pandemics may have negative impacts on our ability to initiate new clinical trial sites, enroll new patients and maintain existing patients who are participating in clinical trials, which may result in increased clinical trial costs, longer timelines and delays in our ability to obtain regulatory approvals of our product candidates, if at all. For example, patient enrollment and recruitment could be delayed due to local clinical trial site protocols designed to protect staff and patients from certain outbreaks, which could delay the expected timelines for data readouts of our preclinical studies and clinical trials. Additionally, general supply chain issues may be exacerbated during disease outbreaks, epidemics or pandemics and may also impact the ability of our clinical trial sites to obtain basic medical supplies used in our trials in a timely fashion, if at all. Moreover, the extent to which disease outbreaks, epidemics and pandemics may impact our business, results of operations and financial position will depend on future developments, which are highly uncertain and cannot be predicted with confidence. New health epidemics or pandemics may emerge that result in similar or more severe disruptions to our business. A future disease outbreak, epidemic or pandemic adversely affects our business, financial condition, results of operations and growth prospects. Our business operations were previously interrupted and delayed as a result of the COVID-19 pandemic. Specifically, we experienced delays in engaging clinical sites as a result of a backlog of clinical trial protocols requiring site review created by an accumulation of protocols while clinical trials and the clinical trial review process had been widely disrupted during the pandemic. Additionally, site initiation, participant recruitment and enrollment, participant dosing, distribution of clinical trial materials, study monitoring, data analysis, and laboratory research activities had been paused or delayed due to changes in hospital or university policies, federal, state or local regulations, prioritization of hospital resources toward pandemic efforts, or other reasons related to the COVID-19 pandemic. During the COVID-19 pandemic, we had also experienced disruptions in our supply chain regarding our manufacturing and testing operations. The future progression of the COVID-19 epidemic and its effects on our business and operations are uncertain. The impacts of a potential resurgence of COVID-19 could pose the risk that we or our employees, suppliers, customers and others may be restricted or prevented from conducting business activities for indefinite or intermittent periods of time, including as a result of employee health and safety concerns, shutdowns, shelter in place orders, travel restrictions and other actions and restrictions that may be prudent or required by governmental authorities. This could disrupt our ability to operate our business, including producing drug product and administering our preclinical and clinical studies. In addition, fluctuations in demand and other implications associated with the COVID-19 pandemic have resulted in, and could continue resulting in, certain supply chain constraints and challenges in the broader markets and economy generally, which could impact our business and supply sources, including our CDMOs. 53 We face competition from other biotechnology and pharmaceutical companies, particularly those that are gene therapy companies, and our operating results will suffer if we fail to compete effectively. The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. This is particularly so in the fast- growing gene therapy space. We face competition from domestic and international competitors including major multinational pharmaceutical and biotechnology companies, specialty pharmaceutical and generic drug companies, academic institutions, government agencies and other public and private research institutions. Many of our competitors have greater financial and other resources, such as larger research and development staff and more experienced marketing and manufacturing organizations than we do. Large pharmaceutical companies, in particular, have extensive experience in clinical testing, obtaining regulatory approvals, recruiting patients and manufacturing pharmaceutical products. These companies also have significantly greater research, sales and marketing capabilities and collaborative arrangements in our target markets with leading companies and research institutions. Established pharmaceutical companies may also invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make the product candidates that we develop obsolete. As a result of these factors, our competitors may succeed in obtaining patent protection and/or FDA or other regulatory approval or in discovering, developing and commercializing drugs for the indications that we are targeting before we do or may develop drugs that are deemed to be more effective or gain greater market acceptance than ours. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies. If our competitors market products that are more effective, safer or less expensive or reach the market sooner than our future products, if any, we may not achieve commercial success. In addition, because of our limited resources, it may be difficult for us to stay abreast of the rapid changes in all technologies that are or may become competitive with ours. If we fail to stay at the forefront of technological change, we may be unable to compete effectively. Technological advances or products developed by our competitors may render our technologies or product candidates obsolete, less competitive or not economical. Risks Related to Regulatory Approval and Marketing of Our Current and Future Product Candidates and Other Legal Compliance Matters We cannot provide assurance that REQORSA, GPX-002, or any of our other current or future product candidates will receive regulatory approval, and without regulatory approval we will not be able to market them. Our business currently depends largely on the successful development and commercialization of REQORSA, GPX-002, and our other current product candidates. Our ability to generate revenue related to product sales will depend on the successful development and regulatory approval of REQORSA for the treatment of cancer and/or GPX-002 for diabetes. Even if we complete the necessary clinical studies, we cannot predict when or if we will obtain regulatory approval to commercialize a product candidate. Further, even if we obtain regulatory approval, it may only apply to a narrower indication than we expect and our products will remain subject to regulatory scrutiny. We currently have no products approved for sale and we cannot guarantee that we will ever have marketable products. The development of a product candidate and issues relating to its approval and marketing are subject to extensive regulation by the FDA in the United States and regulatory authorities in other countries, with regulations differing from country to country. We are not permitted to market our product candidates in the United States until we receive approval of a BLA from the FDA. We have not submitted any marketing applications for any of our current and potential product candidates. BLAs must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety and effectiveness for each desired indication. BLAs must also include significant information regarding the chemistry, manufacturing and controls for the product. Obtaining approval of a BLA is a lengthy, expensive and uncertain process, and we may not be successful in obtaining approval. The FDA review processes can take years to complete, and approval is never guaranteed. If we submit a BLA to the FDA, the FDA must decide whether to file the BLA or refuse to file it. We cannot be certain that any submissions will be filed and reviewed by the FDA. In addition, regulators in other jurisdictions have their own procedures for approval of product candidates. 54 The FDA or regulators in other jurisdictions could delay, limit or deny approval of a product candidate for many reasons, including because they: ● may not deem our product candidate to be safe and effective; ● determine that the product candidate does not have an acceptable benefit-risk profile; ● determine in the case of a BLA seeking accelerated approval that the BLA does not provide evidence that the product candidate represents a meaningful advantage over available therapies; ● determine that the results on our primary endpoints are not clinically meaningful; ● may not agree that the data collected from preclinical studies and clinical trials are acceptable or sufficient to support the approval of a BLA or other submission or to obtain regulatory approval, and may impose requirements for additional preclinical studies or clinical trials; ● may determine that adverse events experienced by participants in our clinical trials represent an unacceptable level of risk; ● may determine that population studied in the clinical trial may not be sufficiently broad or representative to assure safety in the full population for which we seek approval; ● may disagree regarding the formulation or the specifications of our product candidates; ● may not approve the manufacturing processes associated with our product candidate or may determine that a manufacturing facility does not have an acceptable compliance status; or ● may change approval policies or adopt new regulations. Even if a product is approved, the FDA may limit the indications for which the product may be marketed, require extensive warnings on the product labeling or require expensive and time-consuming clinical trials or reporting as conditions of approval. Regulatory authorities in countries outside of the United States also have requirements for approval of drug candidates with which we must comply prior to marketing in those countries. Obtaining regulatory approval for marketing of a product candidate in one country does not ensure that we will be able to obtain regulatory approval in any other country. Furthermore, regulatory approval for any of our future product candidates may be withdrawn after approval. If we are unable to obtain approval from the FDA or other regulatory agencies for REQORSA, GPX-002, or our other current or future product candidates, or if, subsequent to approval, we are unable to successfully commercialize REQORSA, GPX-002, or our other current or future product candidates, we will not be able to generate sufficient revenue to become profitable or to continue our operations. In addition, the clinical trial requirements of the FDA, the EMA, and other regulatory agencies and the criteria these regulators use to determine the safety and efficacy of a product candidate vary substantially according to the type, complexity, novelty and intended use and market of the potential products. The regulatory approval process for novel product candidates such as ours can be more expensive and take longer than for other, better known or extensively studied pharmaceutical or other product candidates. Regulatory requirements governing gene therapy products have changed frequently and may continue to change in the future. For example, in January 2017, the FDA Oncology Center of Excellence, or the Center of Excellence, was created to leverage the combined skills of regulatory scientists and reviewers with expertise in drugs, biologics, and devices (including diagnostics). While the Center of Excellence is designed to help expedite the development of oncology and malignant hematology-related medical products and support an integrated approach in the clinical evaluation of drugs, biologics and devices for the treatment of cancer, the Center of Excellence may, at times, create confusion within the FDA and especially in the Center of Biologics and Research, which is the primary review division for REQORSA. Gene therapy clinical trials conducted at institutions that receive funding for recombinant DNA research from the NIH, are also subject to review by NExTRAC. In August 2018, the NIH Director issued a statement describing a proposal intended to streamline the federal framework for oversight of gene therapy. The proposal, which the NIH developed in conjunction with the FDA, included amending the NIH Guidelines for Research Involving Recombinant or Synthetic Nucleic Acid Molecules, or NIH Guidelines, to eliminate duplicative review and reporting requirements for human gene transfer protocols. The statement also described NIH’s effort to refocus the role of the RAC to be closer to its original mandate – a transparent forum for science, safety, and ethics of emerging biotechnologies. Accordingly, the NIH Guidelines have been updated to reflect these changes. Additionally, before a clinical trial can begin at an NIH-funded institution, that institution’s IRB, and its Institutional Biosafety Committee will have to review the proposed clinical trial to assess the safety of the study. In addition, adverse developments in clinical trials of gene therapy products conducted by others may cause the FDA or other regulatory bodies to change the requirements for performing studies or for obtaining approval of any of our current and potential product candidates. The regulatory changes discussed herein as well as other existing and future regulatory developments may cause unexpected delays and challenges for companies seeking approval of gene therapy products, like REQORSA, GPX-002, and our other current or future product candidates. 55 These regulatory review committees and advisory groups, and the new guidelines they promulgate, may lengthen the regulatory review process, require us to perform additional studies, increase our development costs, lead to changes in regulatory positions and interpretations, delay or prevent approval and commercialization of our current and potential product candidates or lead to significant post-approval limitations or restrictions. As we advance our current and potential product candidates, we will be required to consult with these regulatory and advisory groups and comply with applicable guidelines. Any delay or failure to obtain, or unexpected costs in obtaining, the regulatory approval necessary to bring a potential product to market could decrease our ability to generate sufficient revenue to maintain our business. Even if we obtain regulatory approval for our product candidates, our products will remain subject to regulatory oversight. Our product candidates for which we obtain regulatory approval will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, promotion, record-keeping and submission of safety and other post-market information. Any regulatory approvals that we receive for our product candidates also may be subject to the specific obligations imposed as a condition for marketing authorization by equivalent authorities in a foreign jurisdiction, particularly by the European Commission, limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase 4 clinical trials, and surveillance to monitor the quality, safety and efficacy of the product. For example, in the United States, the holder of an approved BLA is obligated to monitor and report adverse events and any failure of a product to meet the specifications in the BLA. The holder of an approved BLA also must submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product labeling or manufacturing process. Advertising and promotional materials must comply with the Federal Food, Drug, and Cosmetic Act (“FDCA”) and implementing regulations and are subject to FDA oversight and post-marketing reporting obligations, in addition to other potentially applicable federal and state laws. In the EU, any future advertising and promotion of our products will be subject to EU laws governing promotion of medicinal products, interactions with physicians, misleading and comparative advertising and unfair commercial practices. In addition, other legislation adopted by individual EU Member States may apply to the advertising and promotion of medicinal products. These laws may limit or restrict the advertising and promotion of our products to the general public and may impose limitations on our promotional activities with health care professionals. These laws require that promotional materials and advertising for medicinal products are consistent with the product’s Summary of Product Characteristics (“SmPC”) as approved by the competent authorities. The SmPC is the document that provides information to physicians concerning the safe and effective use of the medicinal product. It forms an intrinsic and integral part of the marketing authorization granted for the medicinal product. Promotion of a medicinal product that does not comport with the SmPC is considered to constitute off-label promotion, which is prohibited in the EU. The applicable laws at EU level and in the individual EU Member States also prohibit the direct-to-consumer advertising of prescription-only medicinal products. Violations of the rules governing the promotion of medicinal products in the EU could be penalized by administrative measures, fines and imprisonment. In addition, product manufacturers and their facilities may be subject to payment of application and program fees and are subject to continual review and periodic inspections by FDA and other regulatory authorities for compliance with cGMP, requirements and adherence to commitments made in the BLA or foreign marketing application. If we, or a regulatory authority, discover previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured or disagree with the promotion, marketing or labeling of that product, a regulatory authority may impose restrictions relative to that product, the manufacturing facility or us, including requiring recall or withdrawal of the product from the market or suspension of manufacturing. If we fail to comply with applicable regulatory requirements for any product following approval, a regulatory authority may: ● issue a warning or untitled letter asserting that we are in violation of the law; ● seek an injunction or impose administrative, civil or criminal penalties or monetary fines; ● suspend or withdraw regulatory approval; ● suspend any ongoing clinical trials; ● refuse to approve a pending BLA or comparable foreign marketing application (or any supplements thereto) submitted by us or our strategic partners; ● restrict the marketing or manufacturing of the product; ● seize or detain the product or otherwise demand or require the withdrawal or recall of the product from the market; ● refuse to permit the import or export of products; ● request and publicize a voluntary recall of the product; or ● refuse to allow us to enter into supply contracts, including government contracts. 56 Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and adversely affect our business, financial condition, results of operations and prospects. If the FDA does not find the manufacturing facilities of our current or future contract manufacturers acceptable for commercial production, we may not be able to commercialize REQORSA, GPX-002, or any of our other current or future product candidates. We do not have the internal infrastructure or facilities to manufacture ourselves REQORSA, or earlier stage GPX-002 which is in preclinical development, or any other current or future product candidate, and intend to rely on CDMOs for clinical trial needs and commercial supply. However, our strategy could change in the future and we could choose to develop such infrastructure. We do not have agreements for all of the steps relating to the ongoing supply of REQORSA or any of our other product candidates, and we may not be able to reach agreements with these or other contract manufacturers for sufficient supplies to complete clinical development and commercialize REQORSA or any of our other product candidates, if any of them are approved. The manufacture of gene therapy products is complex, and for CDMOs with whom we have agreements, there is no guarantee that they will be able to perform as required on a timely, consistent basis under the applicable governing agreement. Additionally, the facilities used by our contract manufacturers to manufacture product candidates must be the subject of a satisfactory inspection before the FDA approves the product candidate manufactured at that facility. We are completely dependent on our third-party manufacturers for compliance with the requirements of U.S. and non-U.S. regulators for the manufacture of our finished products. If our manufacturers cannot successfully manufacture materials that conform to our specifications and the FDA’s cGMP standards and other requirements of any governmental agency to whose jurisdiction, we are subject, our product candidates will not be approved or, if already approved, may be subject to recalls. Reliance on third-party manufacturers entails risks including: ● the possibility that we are unable to enter into manufacturing agreements with third parties to manufacture our product candidates on acceptable terms; ● the possibility that our contract manufacturers may breach the terms of their manufacturing agreements with us; ● the possibility that our contract manufacturers may experience failures in product production; and ● the possibility of termination or nonrenewal of any manufacturing agreement we may enter into. Any of these factors could cause the delay of approval or commercialization of our product candidates, cause us to incur higher costs or prevent us from commercializing our product candidates successfully. Furthermore, if our product candidates are approved for commercialization and our contract manufacturers fail to deliver the required commercial quantities of finished product on a timely basis at commercially reasonable prices, we would likely be unable to meet demand for our products and could lose potential revenue. It may take several years to establish an alternative source of supply for our product candidates and to have any such new source approved by the government agencies that regulate our products. We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws and other federal and state healthcare laws, and the failure to comply with such laws could result in substantial penalties. Our employees, independent contractors, consultants, principal investigators, CROs, commercial partners and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements. State and federal regulatory and enforcement agencies continue actively to investigate violations of health care laws and regulations, and the United States Congress continues to strengthen the arsenal of enforcement tools. The Bipartisan Budget Act of 2018 increased the criminal and civil penalties that can be imposed for violating certain federal health care laws, including the Anti-Kickback Statute. Enforcement agencies also continue to pursue novel theories of liability under these laws. Government agencies have increased regulatory scrutiny and enforcement activity with respect to programs supported or sponsored by pharmaceutical companies, including reimbursement and co-pay support, funding of independent charitable foundations and other programs that offer benefits for patients. Several investigations into these types of programs have resulted in significant civil and criminal settlements. 57 We are exposed to the risk of fraud, misconduct or other illegal activity by our employees, independent contractors, consultants, principal investigators, CROs, commercial partners and vendors. Misconduct by these parties could include intentional, reckless and/or negligent conduct that fails to: comply with the laws of the FDA and similar foreign regulatory bodies; provide true, complete and accurate information to the FDA and similar foreign regulatory bodies; comply with manufacturing standards we have established; comply with federal and state data privacy, security, fraud and abuse and other healthcare laws and regulations in the United States and similar foreign fraudulent misconduct laws; or report financial information or data accurately or to disclose unauthorized activities to us. If we obtain FDA approval for any of our product candidates and begin commercializing those products in the United States, our potential exposure under such laws would increase significantly, and our costs associated with compliance with such laws would likely also increase. These laws may impact, among other things, our current activities with principal investigators and research patients, as well as proposed and future sales, marketing and education programs and interactions with physicians and other health care providers. In particular, the promotion, sales and marketing of healthcare items and services, as well as certain business arrangements in the healthcare industry, are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, including off-label uses of our products, structuring and commission(s), certain customer incentive programs and other business arrangements generally. Activities subject to these laws also involve the improper use or misrepresentation of information obtained in the course of patient recruitment for clinical trials, creating fraudulent data in our preclinical studies or clinical trials or illegal misappropriation of drug product, which could result in regulatory sanctions and cause serious harm to our reputation. Additionally, we are subject to the risk that a person or government could allege such fraud or other misconduct, even if none occurred. 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 fines or other sanctions. The laws that may affect our ability to operate include, but are not limited to: ● the Federal Anti-Kickback Statute, which prohibits, among other things, individuals and entities from knowingly and willfully soliciting, receiving, offering or paying any remuneration (including any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce, or in return for, either the referral of an individual for, or the purchase, lease, order or recommendation of, any good, facility, item or service for which payment may be made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation; ● federal civil and criminal false claims laws and civil monetary penalty laws, including the civil False Claims Act, which impose criminal and civil penalties, through government, civil whistleblower or qui tam actions, on individuals and entities for, among other things, knowingly presenting, or causing to be presented, claims for payment or approval from Medicare, Medicaid, or other third-party payors that are false, fictitious or fraudulent, or knowingly making, using or causing to be made or used, a false statement to avoid, decrease or conceal an obligation to pay money to the federal government. In addition, the government may assert that a claim including items and services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act; ● HIPAA imposes criminal and civil liability for, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud or to obtain any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or private), willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false, fictitious or fraudulent statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters; ● HIPAA, as amended by HITECH and their respective implementing regulations, which impose requirements on certain covered healthcare providers, health plans, and healthcare clearinghouses, as well as their respective business associates that perform services for them that involve the creation, use, maintenance or disclosure of, individually identifiable health information, relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization; ● the federal physician payment transparency requirements, sometimes referred to as the “Physician Payments Sunshine Act,” created under the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (the Affordable Care Act) and its implementing regulations, which require certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to the United States Department of Health and Human Services information related to payments or other transfers of value made to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members; ● the U.S. FDCA, which prohibits, among other things, the adulteration or misbranding of drugs; ● the Foreign Corrupt Practices Act and similar worldwide anti-bribery laws, which generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business; ● federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers; and ● state and foreign equivalents of each of the healthcare laws described above, among others, some of which may be broader in scope and may apply regardless of the payor. It is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent inappropriate conduct 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. Efforts to ensure that our business arrangements will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental and enforcement authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law interpreting applicable fraud and abuse or other healthcare laws and 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 civil, criminal and administrative penalties, damages, disgorgement, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. In addition, the approval and commercialization of any of our current and potential product candidates outside the United States will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws. 58 Coverage and reimbursement may be limited or unavailable in certain market segments for REQORSA, GPX-002, and our other current or future product candidates, if approved, which could make it difficult for us to sell REQORSA, GPX-002, and our other current or future product candidates profitably. The commercial success of any current or future product candidate will depend upon the degree of market acceptance by physicians, patients, insurance companies and other third-party payors, and others in the medical community. Even if we obtain approval to commercialize our current and potential product candidates outside of the United States, a variety of risks associated with international operations could materially affect our business. Due to the novel nature of our technology, we face uncertainty related to pricing and reimbursement for our current and potential product candidates. The insurance coverage and reimbursement status of newly approved products is uncertain. Failure to obtain or maintain adequate coverage and reimbursement for new or current products could limit our ability to market those products and decrease our ability to generate revenue. If market opportunities for our current and potential product candidates are smaller than we believe they are, our revenues may be adversely affected and our business may suffer. Successful sales of our products, if our current and potential product candidates are approved, depend on the availability of coverage and adequate reimbursement from third-party payors. In addition, because our current and potential product candidates represent new approaches to the treatment of cancer and diabetes, we cannot be sure that coverage and reimbursement will be available for, or accurately estimate the potential revenue from, our current and potential product candidates. Patients who are provided medical treatment for their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Coverage and adequate reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and commercial payors are critical to new product acceptance. Government authorities and other third-party payors, such as private health insurers and health maintenance organizations, decide which drugs and treatments they will cover and the amount of reimbursement. Coverage and reimbursement by a third-party payor may depend upon a number of factors, including, but not limited to, the third-party payor’s determination that use of a product is: ● ● ● ● ● a covered benefit under its health plan; safe, effective and medically necessary; appropriate for the specific patient; cost-effective; and neither experimental nor investigational. In the United States, no uniform policy of coverage and reimbursement for products exists among third-party payors, and coverage and reimbursement for products can differ significantly from payor to payor. As a result, obtaining coverage and reimbursement approval of a product from a government or other third-party payor is a time-consuming and costly process that could require us to provide to each payor supporting scientific, clinical and cost-effectiveness data for the use of our products and to justify the level of coverage and reimbursement relative to other therapies, with no assurance that coverage and adequate reimbursement will be obtained. Third party payors may also have difficulty in determining the appropriate coverage of REQORSA and our other current and future product candidates that are combination products, if approved, due to the fact that they are combination products that include another drug. To the extent there are any delays in determining such coverage or inadequate coverage and reimbursement for all aspects of our combination therapies, it would adversely affect the market acceptance, demand and use of our current and potential product candidates. Any denial in coverage or reduction in reimbursement from Medicare or other government programs may result in a similar denial or reduction in payments from private payors, which may adversely affect our future profitability. We intend to seek approval to market our product candidates in both the United States and in selected foreign jurisdictions. If we obtain approval in one or more foreign jurisdictions for our product candidates, we will be subject to rules and regulations in those jurisdictions. In some foreign countries, particularly those in the European Union, the pricing of biologics is subject to governmental control and other market regulations which could put pressure on the pricing and usage of our current and potential product candidates. In these countries, pricing negotiations with governmental authorities can take considerable time after obtaining marketing approval of a product candidate. In addition, market acceptance and sales of our current and potential product candidates will depend significantly on the availability of coverage and adequate reimbursement from third-party payors for our current and potential product candidates and may be affected by existing and future health care reform measures. Concerns about gene therapy, genetic testing, and genetic research could result in new and/or additional government regulations and requirements that restrict or prohibit the processes we use or delay or prevent the regulatory approval of our current and potential product candidates. Ethical, social, and legal concerns about gene therapy, genetic testing, and genetic research could result in additional regulations restricting or prohibiting the processes we may use. Federal and state agencies, congressional committees and foreign governments have expressed interest in further regulating biotechnology. More restrictive regulations or claims that our products are unsafe or pose a hazard could prevent us from commercializing any products. New government requirements may be established that could delay or prevent regulatory approval of our current and potential product candidates. It is impossible to predict whether legislative changes will be enacted, regulations, policies, or guidance changed, or interpretations by agencies or courts changed, or what the impact of such changes, if any, may be. 59 Healthcare legislative reform measures may have a material adverse effect on our business and results of operations. Third-party payors, whether domestic or foreign, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In both the United States and certain foreign jurisdictions, there have been a number of legislative and regulatory changes to the health care system that could affect our ability to sell our products profitably. In particular the Affordable Care Act and its implementing regulations, among other things, subjected biological products to potential competition by lower-cost biosimilars, revised the methodology by which rebates owed by manufacturers to the state and federal government for covered outpatient drugs and certain biologics, including our current and potential product candidates, under the Medicaid Drug Rebate Program are calculated, increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program, extended the Medicaid Drug Rebate program to utilization of prescriptions of individuals enrolled in Medicaid managed care organizations, subjected manufacturers to new annual fees and taxes for certain branded prescription drugs, and provided incentives to programs that increase the federal government’s comparative effectiveness research. More recently, other legislative changes that affect the pharmaceutical industry have been proposed and adopted in the United States since the Affordable Care Act was enacted. For example, the Inflation Reduction Act of 2022 included, among other things, a provision that authorizes CMS to negotiate a “maximum fair price” for a limited number of high-cost, single-source drugs every year, and another provision that requires drug companies to pay rebates to Medicare if prices rise faster than inflation. In addition, various states have adopted or are considering adopting laws that require pharmaceutical companies to provide notice prior to raising prices and to justify price increases. We expect that additional healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, and in turn could significantly reduce the projected value of certain development projects and reduce our profitability. There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state levels directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. We cannot predict the initiatives that may be adopted in the future. The continuing efforts of the government, insurance companies, managed care organizations and other payors of healthcare services to contain or reduce costs of healthcare and/or impose price controls may adversely affect: ● ● ● ● ● the demand for our current and potential product candidates, if we obtain regulatory approval; our ability to set a price that we believe is fair for our products; our ability to generate revenue and achieve or maintain profitability; the level of taxes that we are required to pay; and the availability of capital. 60 We are subject to a variety of risks associated with international operations which could materially adversely affect our business. We anticipate that we will be subject to additional risks in commercializing our product candidates outside the United States, including the following, any one or combination of which could have a material adverse effect on our business: ● ● ● ● ● ● ● ● ● ● different regulatory requirements for approval of product candidates in foreign countries; reduced protection for intellectual property rights; unexpected changes in tariffs, trade barriers and regulatory requirements; economic weakness, including inflation, or political instability in particular foreign economies and markets; compliance with tax, employment, immigration and labor laws for employees living or traveling abroad; compliance with international data privacy laws, including GDPR; foreign currency fluctuations, which could result in increased operating expenses and reduced revenues, and other obligations incident to doing business in another country; workforce uncertainty in countries where labor unrest is more common than in the United States; production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and business interruptions resulting from geopolitical actions, including war and terrorism or natural disasters including earthquakes, typhoons, floods, fires and medical epidemics. If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business. We may become subject to federal, state, local, and foreign laws and regulations governing the use, manufacture, storage, handling and disposal of hazardous materials and certain waste products, including numerous environmental, health and safety laws and regulations, such as those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations may in the future involve the use of hazardous materials, including chemicals and biological materials. Our operations may also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties. In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our research, development or production efforts. Failure to comply with these laws and regulations may also result in substantial fines, penalties or other sanctions. Risks Related to Our Dependence on Third Parties We may not be successful in establishing and maintaining development and commercialization collaborations, which could adversely affect our ability to develop our current and future product candidates and our financial condition and operating results could be adversely affected. Because developing pharmaceutical products, conducting clinical trials, obtaining regulatory approval, establishing manufacturing capabilities and marketing approved products are expensive, we have and may continue to enter into collaborations with companies that have the required expertise. Additionally, if any of our product candidates receive marketing approval, we may enter into sales and marketing arrangements with third parties. If we are unable to enter into arrangements on acceptable terms, or at all, we may be unable to effectively market and sell our products in our target markets. We expect to face competition in engaging collaborators. We may not be successful in our efforts to establish and implement collaborations or other alternative arrangements for the development of our current and potential product candidates. When we collaborate with a third party for development and commercialization of a product candidate, we can expect to relinquish some or all of the control over the timing and future success of that product candidate to such third party. One or more of our collaboration partners may not devote sufficient resources to the development and commercialization of our product candidates or may otherwise fail in these efforts. The terms of any collaboration or other arrangement that we establish may contain provisions that are not favorable to us. In addition, any collaboration that we enter into may not be successful in the development and commercialization of our product candidates. In some cases, we may be responsible for continuing preclinical and initial clinical development of a product candidate or research program under a collaboration arrangement, and the payment we receive from our collaboration partner may be insufficient to cover the cost of such development. If we are unable to reach agreements with suitable collaborators for our product candidates, we may face increased costs, we may be forced to limit the number of our product candidates we can commercially develop or the territories in which we commercialize them. As a result, we may be unable to commercialize products or programs if we are unable to engage a suitable collaborator, which may have a material adverse effect on our operating results and financial condition. 61 We rely, in part, and expect to continue to rely, in part, on third parties to conduct, supervise and monitor our clinical trials, and if these third parties perform in an unsatisfactory manner, it may harm our business. We rely in part on CROs and clinical trial sites to ensure our clinical trials are conducted properly and on time. While we have or will have agreements governing their activities, we may have limited influence over their actual performance because we control only certain aspects of our CROs’ activities. Nevertheless, we are responsible for ensuring that each of our clinical trials is conducted in accordance with the applicable protocol and legal, regulatory and scientific standards, and our reliance on the CROs does not relieve us of our regulatory responsibilities. These CROs may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials or other drug development activities that could harm our competitive position. We and our CROs are required to comply with good clinical practices (“GCPs”) for conducting, recording and reporting the results of clinical trials to assure that the data and reported results are credible and accurate and that the rights, integrity and confidentiality of clinical trial participants are protected. The FDA enforces these GCPs through periodic inspections of study sponsors, principal investigators and clinical trial sites. If we or our CROs fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable, and the FDA may require us to perform additional clinical trials before approving any marketing applications. In addition, our ongoing and future clinical trials will require a sufficient number of test subjects to evaluate the safety and effectiveness of our current and potential product candidates. Accordingly, if our CROs fail to comply with applicable regulations or fail to recruit a sufficient number of patients, we may be required to repeat such clinical trials, which would delay the regulatory approval process. If our CROs do not successfully carry out their contractual duties or obligations, fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to their failure to adhere to our clinical protocols or regulatory requirements, or for any other reasons, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for or successfully commercialize our product candidates. As a result, our financial results and the commercial prospects may be harmed, our costs could increase and our ability to generate revenues could be limited or delayed. We rely, and expect to continue to rely, on third parties to distribute, manufacture and perform release testing for our current and future product candidates and other key materials and if such third parties do not carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approvals for our product candidates. We rely, and expect to continue to rely on third-party CDMOs to produce REQORSA and expect to do so with GPX-002 and other current and future product candidates and other key materials and on third-party contract testing organizations, or CTOs, for the establishment and performance of validated product release assays. Additionally, any CDMO may not have specific experience producing our product candidates at commercial levels and may not achieve the necessary regulatory approvals or produce our products at the quality, quantities, locations and timing needed to support commercialization. We do not have full control of these CDMOs, and they may prioritize other customers or be unable to provide us with enough manufacturing capacity to meet our objectives. We may change our manufacturing process, and there can be no guarantee that the regulatory authorities will approve any new process in a timely manner, or ever. Also, as a consequence of the manufacturing change, there may be a requirement to conduct additional preclinical safety or efficacy studies, develop new manufacturing and release assays and/or repeat all or part of the ascending dose safety study in animals or humans. Regulatory requirements ultimately imposed could adversely affect our ability to test, manufacture or market products. Historically, part of our manufacturing process was conducted in manufacturing facilities at MD Anderson. We have completed the technology transfer from MD Anderson to experienced commercial contract development and manufacturing organizations and have scaled-up clinical production of REQORSA appropriate for our Acclaim-1, Acclaim-2 and Acclaim-3 clinical trials. With the advancement of the development of GPX-002, we also are working to optimize the manufacture of this product candidate and to source high quality and integrated vendors capable of producing it in accordance with GMP. No assurance can be given that such contract manufacturers will be able to, and will receive all approvals to, produce product sufficient for all of our clinical trial needs moving forward or for commercialization. In accordance with cGMPs, changing manufacturers may require the re-validation of manufacturing processes and procedures, and may require further preclinical studies or clinical trials to show comparability between the materials produced by different manufacturers. Changing our contract manufacturers may be difficult and could be costly if we do make such a change, which could result in our inability to manufacture our product candidates and a delay in the development of our product candidates and their commercial sale, should they be approved. Further, in order to maintain our development timelines in the event of a change in a third-party contract manufacturer, we may incur higher costs to manufacture our product candidates. There can be no guarantee that the regulatory authorities will approve any new process in a timely manner or ever. Regulatory requirements ultimately imposed could adversely affect our ability to test, manufacture or market products. In connection with our manufacturing activities, we may encounter technical or scientific issues related to manufacturing or development that we may be unable to resolve in a timely manner or with available funds. Further, we have not fully completed the characterization and validation activities necessary for commercial and regulatory approvals. If our manufacturing and testing partners do not enable such regulatory approvals, our commercialization efforts may be harmed. If such third-party manufacturers are unable to produce REQORSA, GPX-002, or other product candidates in the necessary quantities, or in compliance with cGMP or in compliance with pertinent regulatory requirements, and within our planned time frame and cost parameters, the development and sales of our products, if approved, would be materially harmed. The manufacturing processes used by our contract manufacturers to manufacture product candidates must be approved by the FDA as part of our BLA package and the facilities used by our contract manufacturers must maintain a compliance status acceptable to the FDA pursuant to inspections that will be conducted after we submit our BLA to the FDA. Although we provide specifications, we do not control the manufacturing process of, and are completely dependent on, our contract manufacturing partners for compliance with cGMPs for the manufacture of our product candidates. If our CDMOs cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or other regulatory agencies, we will not be able to secure and/or maintain regulatory approval covering their manufacturing facilities. In addition, we have limited control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly affect our ability to develop, obtain regulatory approval for or market our future product candidates, if approved. In addition, any failure to achieve and maintain compliance with these laws, regulations and standards could subject us to the risk that we may have to suspend the manufacturing of our current and future product candidates or that obtained approvals could be revoked, which would adversely affect our business and reputation. 62 In addition, any significant disruption in our supplier relationships could harm our business. We source key materials, devices and equipment from third parties, either directly through agreements with suppliers or indirectly through our manufacturers who have agreements with suppliers. There is a small number of suppliers for certain key materials and components that are used to manufacture our current and future product candidates. Such suppliers may not sell these key materials to our manufacturers at the times or quantities we need them or on commercially reasonable terms. We may not have any control over the process or timing of the acquisition of these key materials by our manufacturers. We also expect to rely on other third parties to store and distribute our products for our clinical trials. Any performance failure on the part of these third parties could delay clinical development or marketing approval of our current and future product candidates or commercialization of our products, if approved, producing additional losses and depriving us of potential product revenue. We have completed and may in the future complete related party transactions that were not and may not be conducted on an arm’s length basis. If we are successful in commercializing REQORSA, our lead drug candidate, we will owe IRI a 1% royalty of our product sales. REQORSA is based upon patents and related technology covered by the 1994 MD Anderson License Agreement, under which we have rights to patents covering use of various genes, including the TUSC2 gene, for treatment of cancer, as well as know-how and related intellectual property. In 2007, the 1994 MD Anderson License Agreement was sublicensed by Introgen to IRI and in 2009 this sublicense was assigned by IRI to us, and we granted back to IRI a nonexclusive, royalty-free license to use and practice the licensed technology for non-commercial research purposes. As consideration for this assignment, we agreed to assume all of IRI’s obligations to MD Anderson under the 1994 MD Anderson License Agreement, including ongoing patent related expenses and royalty obligations. IRI also agreed in 2011, pursuant to the 2011 IRI Collaboration Agreement, to provide additional technology licensing opportunities and services to us in return for monthly payments and our obligation to pay to IRI a royalty of 1% on sales of products licensed to us under the 1994 MD Anderson License Agreement. We also granted a non-exclusive, royalty-free sublicense to IRI in 2011 for non-commercial research purposes. IRI’s obligations to provide additional technology licensing opportunities and services to us, and our obligation to make monthly payments to IRI, were terminated in 2012; however, our obligation to pay the 1% royalty to IRI upon sales of products licensed to us under the 1994 MD Anderson License Agreement is ongoing. This royalty obligation continues for 21 years after the later of the termination of the 1994 MD Anderson License Agreement and the termination of the sublicense assigned by IRI to us. IRI is controlled by Rodney Varner and IRI is owned by trusts for the benefit of Mr. Varner’s descendants. Mr. Varner is currently Chairman of our board of directors, having joined our board of directors on August 15, 2012, and has been our Chief Executive Officer since August 29, 2012 and President since August 10, 2020; accordingly, in 2009 and 2011, when the above referenced agreements between IRI and Genprex were entered into, Mr. Varner was neither a member of our board of directors nor an executive officer of Genprex. When the 2011 IRI Collaboration Agreement was entered into, Mr. Varner was deemed to be an “affiliate” of the Company due to his beneficial ownership of approximately 39% of our issued and outstanding shares at that time. Although we believe that these transactions were conducted on an arm’s length basis, it is possible that the terms were less favorable to us than they might have been in a transaction with an unrelated party. Disruptions in the global economy and supply chains may have a material adverse effect on our business, financial condition and results of operations. The disruptions to the global economy since the COVID-19 global pandemic commenced in 2020 has impeded global supply chains, resulting in longer lead times and also increased critical component costs and freight expenses. We have experienced this impact most notably in our manufacturing operations due to the delay in our ability to acquire raw materials for our drug product. This delay has the potential to impact the timing of the conduct of our clinical trials. We have taken steps to minimize the impact of these increased costs by working closely with our suppliers and locating redundant or comparable sources. Despite the actions we have undertaken to minimize the impacts from disruptions to the global economy, there can be no assurances that unforeseen future events in the global supply chain, and inflationary pressures, will not have a material adverse effect on our business, financial condition and results of operations. 63 Risks Related to Our Intellectual Property If we fail to comply with obligations pursuant to our license agreements, we could lose intellectual property and other rights that are important to our business; if we fail to obtain licenses to advance our research and development that may be required we may be unable to develop the affected product exclusively, on acceptable terms or at all. Pursuant to the 1994 MD Anderson License Agreement and subsequent Amendments thereto, as well as the 2020 MD Anderson License Agreement, we hold worldwide, exclusive license rights to certain inventions covering the therapeutic use of TUSC2 and other genes and polypeptides that have been shown to have cancer fighting properties, as well as a number of related technologies. In addition, pursuant to the UP License Agreements, UP granted us a worldwide, exclusive license to certain licensed technology, and a worldwide, non-exclusive license to use certain related know-how, all related to diabetes gene therapy. In addition, we expect to enter into additional license agreements in the future. Our existing and future license agreements may impose various payment and other obligations on us. If we fail to comply with our obligations under these agreements, our licensors may have the right to terminate our licenses, in which event we would not be able to market products covered by such licenses. Moreover, in the event we need to obtain licenses from third parties to advance our research and development or allow commercialization of our product candidates, including additional technology that may be required or advisable to advance REQORSA or GPX-002, we may fail to obtain any of such licenses at a reasonable cost or on reasonable terms, if at all. In that event, we may be required to expend significant time and resources to develop or license replacement technology. If we are unable to develop or license replacement technology, we may be unable to develop or commercialize the affected product candidates, which could harm our business significantly. We cannot provide any assurances that third-party patents do not exist which might be enforced against our current product candidates or future products, resulting in either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of compensation to third parties or that we may be estopped from acquiring such rights due to prior art. Specifically, mice and NHP studies for which we have disclosed data relating to our diabetes program includes a technology to which we do not have exclusive rights, though we expect, but are not guaranteed, that we will have exclusive rights to the final product(s) developed under this program. In certain cases, patent prosecution of our licensed technology may be controlled solely by the licensor. If our licensors fail to obtain and maintain patent or other protection for the proprietary intellectual property we license from them, we could lose our rights to the intellectual property or our exclusivity with respect to those rights, and our competitors could market competing products using the intellectual property. Licensing of intellectual property is of critical importance to our business and involves complex legal, business and scientific issues and is complicated by the rapid pace of scientific discovery in our industry. Disputes may arise regarding intellectual property subject to a licensing agreement, including, but not limited to: ● the scope of rights granted under the license agreement and other interpretation-related issues; ● the extent to which our technology and processes infringe intellectual property of the licensor that is not subject to the licensing agreement; ● the sublicensing of patent and other rights under our collaborative development relationships; ● our diligence obligations under the license agreement and what activities satisfy those diligence obligations; ● the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners; and ● the priority of invention of patented technology. If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates. 64 The intellectual property rights we have licensed from MD Anderson and the UP are subject to the rights of the U.S. government. The rights we have obtained pursuant to our license agreements with MD Anderson and the UP are made subject to the rights of the U.S. government to the extent that the technology covered by the licensed intellectual property was developed under a funding agreement between such institution and the U.S. government. Additionally, to the extent there is any conflict between our license agreement and applicable laws or regulations, applicable laws and regulations will prevail. Similarly, to the extent there is any conflict between our license agreement with one of these institutions and the institution’s funding agreement with the US government, the terms of the funding agreement will prevail. Some, and possibly all, of our licensed intellectual property rights have been developed in the course of research funded by the U.S. government. As a result, the U.S. government may have certain rights to intellectual property embodied in our current or future products pursuant to the Bayh-Dole Act of 1980. Government rights in certain inventions developed under a government-funded program include a non-exclusive, non-transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, the U.S. government has the right to require us, or an assignee or sublicensee to such inventions, to grant licenses to any of these inventions to a third party if the U.S. government determines that adequate steps have not been taken to commercialize the invention, that government action is necessary to meet public health or safety needs, that government action is necessary to meet requirements for public use under federal regulations, or the right to use or sell such inventions is exclusively licensed to an entity within the U.S. and substantially manufactured outside the U.S. without the U.S. government’s prior approval. Additionally, we may be restricted from granting exclusive licenses for the right to use or sell our inventions created pursuant to such agreements unless the licensee agrees to additional restrictions (e.g., manufacturing substantially all of the invention in the U.S.). The U.S. government also has the right to take title to these inventions if our licensors failed to disclose the invention to the government in a timely manner and/or failed to file an application to register the intellectual property within specified time limits. In addition, the U.S. government may acquire title in any country in which a patent application is not filed within specified time limits. Furthermore, certain inventions are subject to transfer restrictions during the term of these agreements and for a period thereafter, including sales of products or components, transfers to foreign subsidiaries for the purpose of the relevant agreements, and transfers to certain foreign third parties. If any of our intellectual property becomes subject to any of the rights or remedies available to the U.S. government or third parties pursuant to the Bayh-Dole Act of 1980, this could impair the value of our intellectual property and could adversely affect our business. If we are unable to protect our intellectual property rights or if our intellectual property rights are inadequate for our technology and product candidates, our competitive position could be harmed. Our commercial success will depend in part on our ability and the ability of our licensors to obtain and maintain patent and other intellectual property protection in the United States and other countries with respect to our proprietary technology and products. We rely on trade secret, patent, copyright and trademark laws, and confidentiality, licensing and other agreements with employees and third parties, all of which offer only limited protection. We seek to protect our proprietary position by filing and prosecuting patent applications in the United States and abroad related to our novel technologies and products that are important to our business. The patent positions of biotechnology and pharmaceutical companies generally are highly uncertain, involve complex legal and factual questions and have in recent years been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patents, including those patent rights licensed to us by third parties, are highly uncertain. The steps we or our licensors have taken to protect our proprietary rights may not be adequate to preclude misappropriation of our proprietary information or infringement of our intellectual property rights, both inside and outside of the United States. Further, the examination process may require us or our licensors to narrow the claims for our pending patent applications, which may limit the scope of patent protection that may be obtained if these applications issue. The rights already granted under any of our currently issued patents or those licensed to us and those that may be granted under future issued patents may not provide us with the proprietary protection or competitive advantages we are seeking. If we or our licensors are unable to obtain and maintain patent protection for our technology and products, or if the scope of the patent protection obtained is not sufficient, our competitors could develop and commercialize technology and products similar or superior to ours, and our ability to successfully commercialize our technology and products may be adversely affected. It is also possible that we or our licensors will fail to identify patentable aspects of inventions made in the course of our development and commercialization. It is also possible that as research and development progresses, the direction of our intellectual property strategy and patent portfolio will change, resulting in strategic business decisions to allow certain patents or patent applications to be abandoned or lapse. With respect to patent rights, we do not know whether any of the pending patent applications relating to any of our current and future product candidates will result in the issuance of patents that effectively protect our technology or products, or if any of our licensors’ issued patents will effectively prevent others from commercializing competitive technologies and products. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing or in some cases not at all, until they are issued as a patent. Therefore, we cannot be certain that we or our licensors were the first to make the inventions claimed in our owned or licensed patents or pending patent applications, or that we or our licensors were the first to file for patent protection of such inventions. Our pending applications cannot be enforced against third parties practicing the technology claimed in such applications unless and until a patent issues from such applications. Because the issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, issued patents that we have licensed from third parties may be challenged in the courts or patent offices in the United States and abroad. Such challenges may result in the loss of patent protection, the narrowing of claims in such patents or the invalidity or unenforceability of such patents, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection for our technology and products. Protecting against the unauthorized use of our or our licensor’s patented technology, trademarks and other intellectual property rights is expensive, difficult and may in some cases not be possible. In some cases, it may be difficult or impossible to detect third-party infringement or misappropriation of our intellectual property rights, even in relation to issued patent claims, and proving any such infringement may be even more difficult. 65 Third-party claims of intellectual property infringement may prevent or delay our development and commercialization efforts. Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties. There is a substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including patent infringement lawsuits, interferences, oppositions and other post grant proceedings before the US Patent and Trademark Office (“USPTO”) and corresponding foreign patent offices. Numerous US and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are pursuing development candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our current and future product candidates may be subject to claims of infringement of the patent rights of third parties. Third parties may in the future assert that we are employing their proprietary technology without authorization. There may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our product candidates. Because patent applications can take many years to issue, there may be currently pending patent applications which may later result in issued patents that our product candidates may infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. If any third-party patents were held by a court of competent jurisdiction to cover the manufacturing process of any of our product candidates, or any final product itself, the holders of any such patents may be able to block our ability to develop and commercialize such product candidate until such patents expire unless we obtained a license under the applicable patents, which license may not be available on acceptable terms, if at all. Parties making claims against us may obtain injunctive or other equitable relief, which may hinder our ability to further develop and commercialize one or more of our product candidates. Defense of these claims, regardless of their merit, may involve substantial litigation expense and diversion of our management’s attention. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, pay royalties, redesign our infringing products or obtain one or more licenses from third parties, which licenses may not be on acceptable terms or require substantial time and monetary expenditure. We may not be successful in obtaining or maintaining necessary rights to product components and processes for our development pipeline through acquisitions and in-licenses. Presently we believe that we have the necessary rights to the intellectual property, through licenses or other rights from third parties to develop our product candidates. Because our programs may involve additional product candidates that may require the use of proprietary rights held by third parties, the growth of our business may depend in part on our ability to acquire, in-license or use these proprietary rights. In addition, our product candidates may require specific formulations to work effectively and efficiently and these rights may be held by others. We may be unable to acquire or in-license any compositions, methods of use, processes or other third-party intellectual property rights from third parties on reasonable terms, if at all. The licensing and acquisition of third-party intellectual property rights is a competitive area, and a number of more established companies are also pursuing strategies to license or acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage over us due to their size, cash resources and greater clinical development and commercialization capabilities. If we are unable to successfully obtain rights to required third-party intellectual property, our business, financial condition and prospects for growth could suffer. Confidentiality agreements with employees and others may not adequately prevent disclosure of trade secrets and other proprietary information and may not adequately protect our intellectual property. We rely on trade secrets to protect our proprietary technologies, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We rely in part on confidentiality agreements with our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to protect our trade secrets and other proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover our trade secrets and proprietary information. Costly and time- consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position. 66 Our reliance on third parties may require us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed. Because we rely on and intend to continue to rely on third parties to manufacture our current and future product candidates, and because we collaborate with various organizations and academic institutions on the advancement of our product candidates, we must, at times, share trade secrets with them. We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if applicable, material transfer agreements, collaborative research agreements, consulting agreements or other similar agreements with our manufacturers, collaborators, advisors, employees and consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information, such as trade secrets. Despite the contractual provisions of such agreements, the need to share trade secrets and other confidential information increases the risk that such trade secrets may become known by our competitors, may be inadvertently incorporated into the technology of others, may be used inappropriately to create new inventions or may be disclosed or used in violation of such agreements. Our academic collaborators typically have rights to publish data, provided that we are notified in advance and may delay publication for a specified time in order to secure our intellectual property rights arising from the collaboration. In other cases, publication rights are controlled exclusively by us, although in some cases we may share these rights with other parties. We may also conduct joint research and development programs that may require us to share trade secrets under the terms of research and development partnerships or similar agreements. Despite our efforts to protect our trade secrets, our competitors may discover our trade secrets through breach of these agreements, independent development or publication of information including our trade secrets in cases where we do not have proprietary or otherwise protected rights at the time of publication. Given that our proprietary position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or other unauthorized use or disclosure may impair our competitive position and have a material adverse effect on our business. We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time-consuming and unsuccessful. Competitors may infringe our patents or the patents of our licensors. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that a patent is not valid, is unenforceable and/or is not infringed, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing. Interference proceedings provoked by third parties or brought by us may be necessary to determine the priority of inventions with respect to our patents or patent applications or those of our licensors. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Our defense of litigation or interference proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees. We may not be able to prevent, alone or with our licensors, misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the United States. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of our common stock. Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements. Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to be paid to the USPTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the patents and/or applications. We employ an outside firm and rely on our outside counsel to pay these fees due to non-US patent agencies. The USPTO and various non-US governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. Although an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, our competitors might be able to enter the market which would have a material adverse effect on our business. Issued patents covering our product candidates could be found invalid or unenforceable if challenged in court. If we or one of our licensing partners, including MD Anderson or UP, initiate legal proceedings against a third party to enforce a patent covering one of our product candidates, the defendant could counterclaim that the patent covering our product candidate is invalid and/or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including 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. Third parties may also raise similar claims before administrative bodies in the United States or abroad, even outside the context of litigation. Such mechanisms include re-examination, post grant review and equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings). Such proceedings could result in revocation or amendment to our patents in such a way that they no longer cover our current and potential product candidates. The outcome following legal assertions of invalidity and unenforceability 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 and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on our current and potential product candidates. Such a loss of patent protection would have a material adverse impact on our business. 67 We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties or that our employees have wrongfully used or disclosed alleged trade secrets of their former employers. We currently and in the future may employ individuals who were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors. Although we try to ensure that our employees, consultants and independent contractors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed intellectual property, including trade secrets or other proprietary information, of any of our employee’s former employer or other third parties. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel, which could adversely impact our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and result in a diversion of management’s attention. We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property. We may be subject to claims that former employees, collaborators or other third parties have an ownership interest in our patents or other intellectual property. We may have potential ownership disputes arising, for example, from conflicting obligations of consultants, collaborators or others who are involved in developing our current and potential product candidates. Litigation may be necessary to defend against these and other claims challenging inventorship or ownership. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, valuable intellectual property. Such an outcome could have a material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees. Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our products. The United States has enacted and is currently implementing wide-ranging patent reform legislation. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future. We have in the past and may again in the future have trademark applications in the United States and/or certain other countries, and failure to secure these registrations could adversely affect our business; additionally, we may need to enforce our trademark rights against third parties and expend significant resources to enforce such rights against infringement. We have obtained trademark registrations in the United States for GENPREX, ONCOPREX and REQORSA and we may in the future have pending trademark applications in the United States and/or certain other countries. During trademark registration proceedings, our application may be rejected. Although we would be given an opportunity to respond to the rejection of a trademark application, we may be unable to overcome such rejection. In addition, with respect to the USPTO and comparable agencies in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademark, and our trademark may not survive such proceedings. Additionally, we may need to enforce our trademark rights against third parties and expend significant additional resources to enforce such rights against infringement. Moreover, any name we propose to use with our current and potential product candidates in the United States must be approved by the FDA, regardless of whether we have registered it, or applied to register it, as a trademark. The FDA typically conducts a review of proposed product names, including an evaluation of the potential for confusion with other product names. If the FDA objects to any of our proposed proprietary product names, we may be required to expend significant additional resources in an effort to identify a suitable substitute name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA. We may not be able to protect our intellectual property rights throughout the world. Filing, prosecuting and defending patents with respect to product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and further, may export otherwise infringing products to territories where we have patent protection, but enforcement is not as strong as that in the United States. These products may compete with our products and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing. Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license. 68 Risks Related to Employee Matters and Managing Growth We have no sales, marketing or distribution experience and we will have to invest significant resources to develop those capabilities or enter into acceptable third-party sales and marketing arrangements. We have no sales, marketing or distribution experience. To develop sales, distribution and marketing capabilities, we will have to invest significant amounts of financial and management resources, some of which will need to be committed prior to any confirmation that our product candidates will be approved by the FDA. For product candidates for which we decide to perform sales, marketing and distribution functions ourselves or through third parties, we could face a number of additional risks, including that we or our third- party sales collaborators may not be able to build and maintain an effective marketing or sales force, and we may experience difficulty in managing the growth of our organization. If we use third parties to market and sell our products, we may have limited or no control over their sales, marketing and distribution activities on which our future revenues may depend. We may not be able to manage our business effectively if we are unable to attract and retain key personnel and consultants. As of March 15, 2024, we had 26 total employees, all of which were full-time. As we advance our product candidates through preclinical studies and clinical trials, we will need to increase our clinical trial management, product development, manufacturing, regulatory, and administrative headcount to manage these programs. In addition, to meet our obligations as a public company, we may need to increase our general and administrative capabilities. We may not be able to attract or retain qualified personnel and consultants due to the intense competition for qualified personnel and consultants among biotechnology, pharmaceutical and other businesses. If we are not able to attract and retain necessary personnel and consultants to accomplish our business objectives, we may experience constraints that will significantly impede the achievement of our development objectives, our ability to raise additional capital and our ability to implement our business strategy. We are highly dependent on the development, manufacturing, regulatory, commercialization and business development expertise of our management team, key employees and consultants. Any of our executive officers or key employees or consultants may terminate their employment or engagement with us at any time. If we lose one or more of our executive officers or key employees or consultants, our ability to implement our business strategy successfully could be seriously harmed. Replacing executive officers, key employees and consultants may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to develop, gain regulatory approval of and commercialize products successfully. Competition to hire and retain employees and consultants from this limited pool is intense, and we may be unable to hire, train, retain or motivate these additional key personnel and consultants. Our failure to retain key personnel or consultants could materially harm our business. As previously reported in 2022, our Chairman, President and Chief Executive Officer, Rodney Varner, had been diagnosed with a cutaneous lymphoma and has been undergoing chemotherapy and other treatments since then. Mr. Varner has been continuing in his roles at the Company during this period and expects to continue to do so, although he has limited some business activities and travel. Our board of directors had taken steps in 2022 to ensure smooth continuity of business priorities and operations during periods when Mr. Varner was receiving treatments or otherwise unavailable due to his condition. For business continuity, our board of directors has determined that Ryan Confer, our Chief Financial Officer, can and shall act in covering when Mr. Varner is unavailable. In addition to our management team and key employees, we have scientific and clinical advisors and consultants who assist us in formulating our research, development and clinical strategies. These advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us and typically they will not enter into non-compete agreements with us. If a conflict of interest arises between their work for us and their work for another entity, we may lose their services. In addition, our advisors may have arrangements with other companies to assist those companies in developing products or technologies that may compete with ours. We may use our financial and human resources to pursue a particular research program or product candidate and fail to capitalize on programs or product candidates that may be more profitable or for which there is a greater likelihood of success. Because we have limited resources, we may forego or delay pursuit of opportunities with certain programs or product candidates or for indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on research and development programs for product candidates may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through strategic collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate, or we may allocate internal resources to a product candidate in a therapeutic area in which it would have been more advantageous to enter into a partnering arrangement. 69 If we engage in future acquisitions or strategic partnerships, this may increase our capital requirements, dilute our stockholders, cause us to incur debt or assume contingent liabilities, and subject us to other risks. We may evaluate and enter into various acquisitions and strategic partnerships, including licensing or acquiring additional products, intellectual property rights, technologies, or businesses. Any potential acquisition or strategic partnership may entail numerous risks, including: ● ● ● ● ● ● ● ● ● increased operating expenses and cash requirements; the assumption of additional indebtedness or contingent liabilities; the issuance of our equity securities; assimilation of operations, intellectual property and products of an acquired company, including difficulties associated with integrating new personnel; difficulties in achieving anticipated cost savings, synergies, business opportunities, and growth prospects from any business combination; the diversion of our management’s attention from our existing product programs and initiatives in pursuing such a strategic merger or acquisition; retention of key employees, the loss of key personnel, and uncertainties in our ability to maintain key business relationships; risks and uncertainties associated with the other party to such a transaction, including the prospects of that party and their existing products or product candidates and marketing approvals; and our inability to generate revenue from acquired technology and/or products sufficient to meet our objectives in undertaking the acquisition or even to offset the associated acquisition and maintenance costs. Moreover, we may not be able to locate suitable acquisition opportunities and such inability could impair our ability to grow or obtain access to technology or products that may be important to the development of our business. Risks Related to our Securities The market price of our common stock may be highly volatile, and you may lose all or part of your investment. The market price of our common stock has been volatile in the past and is likely to be volatile in the future. Our stock price could be subject to wide fluctuations in response to a variety of factors, including the following: ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● inability to obtain additional funding; adverse results or delays in preclinical or clinical trials; reports of adverse events in other gene therapy products or clinical trials of such products; manufacturing and supply issues related to our existing or future products; any delay in filing an IND or BLA for our product candidates and any adverse development or perceived adverse development with respect to the FDA’s review of that IND or BLA; failure to develop successfully and commercialize our product candidates; failure to maintain our existing strategic collaborations or enter into new collaborations; failure by us or our licensors and strategic collaboration partners to prosecute, maintain or enforce our intellectual property rights; changes in laws or regulations applicable to our products and product candidates; inability to obtain adequate product supply for our product candidates or inability to do so at acceptable prices; adverse regulatory decisions; introduction of new products, services or technologies by our competitors; failure to meet or exceed financial projections we may provide to the public; failure to meet or exceed the financial projections of the investment community; the perception of the pharmaceutical and biotechnology industries by the public, legislatures, regulators and the investment community; announcements of significant acquisitions, strategic partnerships, joint ventures, capital commitments or other material corporate transactions or events by us, our strategic collaboration partners or our competitors; disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our technologies; additions or departures of key scientific or management personnel; significant lawsuits, including patent or stockholder litigation; changes in the market valuations of similar companies; sales of our common stock by us or our stockholders; trading volume of our common stock; material announcements or changes impacting our common stock or our capitalization, or the perception that such changes could occur; and General economic conditions in the United States and abroad; and other events or factors, many of which may be out of our control, including, but not limited to, pandemics, war, or other acts of God. 70 In addition, companies trading in the stock market in general, and The Nasdaq Capital Market in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance. An active, liquid and orderly market for our common stock may not be sustained, and you may not be able to sell your common stock. Our common stock trades on the Nasdaq Capital Market. We cannot assure you that an active trading market for our common stock will be sustained. The lack of an active market may impair your ability to sell the common stock at the time you wish to sell them or at a price that you consider reasonable. An inactive market may also impair our ability to raise capital by selling common stock and may impair our ability to acquire other businesses, applications or technologies using our common shares as consideration, which, in turn, could materially adversely affect our business. We are currently listed on The Nasdaq Capital Market. If we are unable to maintain listing of our securities on Nasdaq or any stock exchange, our stock price could be adversely affected and the liquidity of our stock and our ability to obtain financing could be impaired and it may be more difficult for our stockholders to sell their securities. Although our common stock is currently listed on The Nasdaq Capital Market, we may not be able to continue to meet the exchange’s minimum listing requirements, including the minimum bid price requirement and other applicable corporate governance requirements, or those of any other national exchange. If we are unable to maintain listing on Nasdaq, our common stock may remain thinly traded. The Listing Rules of Nasdaq require listing issuers to comply with certain standards in order to remain listed on its exchange. If, for any reason, we should fail to maintain compliance with these listing standards and Nasdaq should delist our securities from trading on its exchange and we are unable to obtain listing on another national securities exchange, a reduction in some or all of the following may occur, each of which could have a material adverse effect on our stockholders: ● the liquidity of our common stock; ● the market price of our common stock; ● our ability to obtain financing for the continuation of our operations; ● the number of investors that will consider investing in our common stock; ● the number of market makers in our common stock; ● the availability of information concerning the trading prices and volume of our common stock; and ● the number of broker-dealers willing to execute trades in shares of our common stock; Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and stock price. Global credit and financial markets have experienced volatility and disruptions in past years, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, concerns about medical epidemics, and uncertainty about economic stability. We cannot assure you that further deterioration in credit and financial markets and confidence in economic conditions will not occur. Our general business strategy may be adversely affected by any such economic downturn, volatile business environment or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate, or do not improve, it may make any necessary debt or equity financing more difficult, more costly and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance and stock price and could require us to delay or abandon clinical development plans. In addition, there is a risk that one or more of our current service providers, manufacturers and other partners may not survive difficult economic times, which could directly affect our ability to attain our operating goals on schedule and on budget. Failure to maintain effective internal control over our financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002, as amended (“Sarbanes-Oxley Act”) could cause our financial reports to be inaccurate. We are required pursuant to Section 404 of the Sarbanes-Oxley Act, or Section 404, to maintain internal control over financial reporting and to assess and report on the effectiveness of those controls. This assessment includes disclosure of any material weaknesses identified by our management in our internal control over financial reporting. Although we prepare our financial statements in accordance with accounting principles generally accepted in the United States, our internal accounting controls may not meet all standards applicable to companies with publicly traded securities. If we fail to implement any required improvements to our disclosure controls and procedures, we may be obligated to report control deficiencies, in which case we could become subject to regulatory sanction or investigation. Further, such an outcome could damage investor confidence in the accuracy and reliability of our financial statements. 71 Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud. Any failure to implement required or improved controls, or difficulties encountered in their implementation, could cause us to fail to meet our reporting obligations. We have designed, implemented and tested the internal control over financial reporting required to comply with this obligation, which was and is time consuming, costly, and complicated. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Our management has concluded that our internal controls over financial reporting were, and continue to be, ineffective, and as of the year ended December 31, 2023 as a result of material weaknesses in our internal controls due to the lack of segregation of duties between accounting and other functions and the absence of sufficient depth of in-house accounting personnel with the ability to properly account for complex transactions. While management is working to remediate these material weaknesses, there is no assurance that such changes, when economically feasible and sustainable, will remediate the identified material weaknesses or that the controls will prevent or detect future material weaknesses. If we are not able to remediate the material weaknesses or maintain effective internal control over financial reporting, this could result in a material misstatement in our consolidated financial statements and a failure to meet our reporting and financial obligations, which could have a material adverse effect on our business. We have no intention of declaring dividends in the foreseeable future. We have never declared or paid cash dividends on our capital stock, and we do not currently anticipate declaring any dividends in the foreseeable future. We anticipate that we will retain all future earnings for the development, operation, and expansion of our business. Any future determination to declare dividends will be made at the discretion of our board of directors and will depend on, among other factors, our financial condition, operating results, capital requirements, contractual restrictions, general business conditions and other factors that our board of directors may deem relevant. Investors in our common stock should not expect to receive dividend income on their investment, and investors will be dependent on the appreciation of our common stock, if any, to earn a return on their investment. We will likely incur increased costs and devote additional management time to public company reporting and compliance obligations as a result of exiting “emerging growth company” status. We no longer qualify as an emerging growth company under the JOBS Act (our eligibility to qualify as an emerging growth company ended on December 31, 2023, the last day of our fiscal year following the fifth anniversary of our initial public offering). While we were an emerging growth company, we were able to take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and exemptions from the requirements of holding nonbinding advisory votes on executive compensation and stockholder approval of any golden parachute payments not previously approved. Now that we have exited emerging growth company status and we are no longer eligible to take advantage of the corresponding exemptions, we expect our management and other personnel to devote more time and the Company to incur additional costs to comply with the more stringent reporting requirements applicable to companies that are not emerging growth companies. We expect that compliance with these requirements will increase our legal and financial compliance costs and will make some activities more time consuming and costly. We cannot predict or estimate the amount of additional costs we may incur as a result of our exit from emerging growth company status, or the timing of the incurrence of such costs. Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall. If our existing stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market, the market price of our common stock could decline. As of December 31, 2023, we had outstanding options to purchase an aggregate of 285,883 shares of our common stock at a weighted average exercise price of $121.11 per share and warrants to purchase an aggregate of 346,440 shares of our common stock at a weighted average exercise price of $57.79 per share. The exercise of such outstanding options and warrants will result in further dilution of your investment, even if there is no relationship between such sales and the performance of our business. We are unable to predict the effect that sales may have on the market price of our common stock. If any shares of our common stock are sold, or if it is perceived that they will be sold, in the public market, the market price of our common stock could decline. 72 Future sales and issuances of our securities could result in additional dilution of the percentage ownership of our stockholders and could cause our share price to fall. We expect that significant additional capital will be needed in the future to continue our planned operations, including research and development, increased marketing, hiring new personnel, commercializing our products, and continuing activities as an operating public company. To the extent we raise additional capital by issuing equity securities, our stockholders may experience substantial dilution. We may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible securities or other equity securities in more than one transaction, investors may be materially diluted by subsequent sales. We may sell a substantial number of shares of our common stock pursuant to our existing At The Market Offering Agreement with H.C. Wainwright, pursuant to which we have the discretion to deliver placement notices to H.C. Wainwright at any time throughout the term of the At The Market Offering Agreement covering up to such number or dollar amount of shares of our common stock as registered on the prospectus supplement covering the ATM offering, as may be amended or supplemented from time to time; pursuant to such agreement, we have the discretion, subject to market demand, to vary the timing, prices, and quantity of shares sold, and there is no minimum or maximum sales price. Any sales of equity securities, whether pursuant to our At The Market Offering Agreement or otherwise, may also result in material dilution to our existing stockholders, and new investors could gain rights superior to our existing stockholders. If securities or industry analysts do not publish research or reports about us, or if they adversely change their recommendations regarding our common stock, then 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, our industry and our market. If no analyst elects to cover us and publish research or reports about us, the market for our common stock could be severely limited and our stock price could be adversely affected. In addition, if one or more analysts ceases coverage of us or fails to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. If one or more analysts who elect to cover us issue negative reports or adversely change their recommendations regarding our common stock, our stock price could decline. Certain provisions in our organizational documents could enable our board of directors to prevent or delay a change of control. We are authorized to issue up to 10,000,000 shares of preferred stock, none of which are outstanding as of March 15, 2024. This preferred stock may be issued in one or more series, the terms of which may be determined at the time of issuance by our board of directors without further action by stockholders. The terms of any series of preferred stock may include voting rights (including the right to vote as a series on particular matters), preferences as to dividend, liquidation, conversion and redemption rights and sinking fund provisions. The issuance of any preferred stock could materially adversely affect the rights of the holders of our common stock, and therefore, reduce the value of our common stock. The ability of our board of directors to issue preferred stock also could have the effect of discouraging unsolicited acquisition proposals, thus adversely affecting the market price of our common stock. In addition, our organizational documents contain provisions that may have the effect of discouraging, delaying or preventing a change of control of, or unsolicited acquisition proposals, that a stockholder might consider favorable. These include provisions: ● requiring at least 66-2/3% of the voting power of all of our then-outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class, to amend the Amended and Restated Bylaws; ● providing that the authorized number of directors may be changed only by resolution of the board of directors; ● providing that the directors may only be removed with cause and the affirmative vote of the holders of at least 66-2/3% of the voting power of all of our then outstanding shares of capital stock entitled to vote generally at the election of directors; ● providing that all vacancies, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum; ● dividing our board of directors into three classes; ● requiring that any action to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders and not be taken by written consent; ● providing that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide notice in writing in a timely manner and also specify requirements as to the form and content of a stockholder’s notice; ● that do not provide for cumulative voting rights (therefore allowing the holders of a majority of the shares of common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose); and ● providing that special meetings of our stockholders may be called only by the Chairman of the board, our Chief Executive Officer or by the board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors. 73 In addition, Delaware law makes it difficult for stockholders that recently have acquired a large interest in a corporation to cause the merger or acquisition of the corporation against the directors’ wishes. Under Section 203 of the Delaware General Corporation Law, a Delaware corporation may not engage in any merger or other business combination with an interested stockholder for a period of three years following the date that the stockholder became an interested stockholder except in limited circumstances, including by approval of the corporation’s board of directors. Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws contain an exclusive forum provision with respect to certain actions which may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable and discourage lawsuits against us or our current or former directors or officers and/or stockholders in such capacity. Our Amended and Restated Certificate of Incorporation, as may be further amended and restated from time to time, and Amended and Restated Bylaws, as may be further amended from time to time, provide that, unless we consent in writing to the selection of an alternative forum, the following actions must be brought solely and exclusively in the Court of Chancery of the State of Delaware (i) any derivative action or proceeding brought on behalf of us; (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to us or our stockholders; (iii) any action asserting a claim against us or any director or officer or other employee of the Company arising pursuant to any provision of the DGCL, our certificate of incorporation or our bylaws; or (iv) any action asserting a claim against us or any director or officer or other employee of the Company governed by the internal affairs doctrine. We believe that the exclusive forum provision may not apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. We believe that to the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore, we believe that Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers or other employees. Alternatively, if a court were to find the choice of forum provision contained in our Amended and Restated Certificate of Incorporation or Amended and Restated Bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could have a material adverse effect on our business, results of operations, and financial condition. General Risk Factors Obligations associated with being a public company in the United States are expensive and time-consuming, and our management will be required to devote substantial time to compliance matters. As a publicly traded company we incur significant legal, accounting and other expenses. The obligations of being a public company in the United States require significant expenditures and places significant demands on our management and other personnel, including costs resulting from public company reporting obligations under the Securities Exchange Act of 1934, as amended (“Exchange Act”) and the rules and regulations regarding corporate governance practices, including those under the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, and the listing requirements of The Nasdaq Capital Market. These rules require the establishment and maintenance of effective disclosure and financial controls and procedures, internal control over financial reporting and changes in corporate governance practices, among many other complex rules that are often difficult to implement, monitor and maintain compliance with. Moreover, the reporting requirements, rules, and regulations will make some activities more time- consuming and costly, particularly now that we are no longer an “emerging growth company” (our eligibility to qualify as an emerging growth company ended on December 31, 2023, the last day of our fiscal year following the fifth anniversary of our initial public offering). Further, in the event that in the future we were to no longer be eligible to qualify as a “smaller reporting company,” and/or if we become subject to the requirements applicable to accelerated filers or large accelerated filers, including complying with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, our compliance burdens and expenses will further increase. In addition, and as a general matter, we expect the foregoing public company rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance. Our management and other personnel will need to devote a substantial amount of time to ensure that we comply with all of these requirements and to keep pace with new regulations, otherwise we may fall out of compliance and risk becoming subject to litigation or being delisted, among other potential consequences. Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses. Our operations, and those of our CROs, contract manufacturers and other contractors, vendors and consultants, could be subject to power shortages, telecommunications failures, wildfires, water shortages, floods, earthquakes, hurricanes, typhoons, fires, extreme weather conditions, medical epidemics and pandemics and other natural or man-made disasters or business interruptions. The occurrence of any of these business disruptions could seriously harm our operations and financial condition and increase our costs and expenses. Our ability to obtain clinical supplies of our current and potential product candidates could be disrupted if the operations of our contract manufacturers are affected by a man-made or natural disaster or other business interruption. 74 In addition, the global macroeconomic environment could be negatively affected by, among other things, new variants of the COVID-19 pandemic or other epidemics, instability in global economic markets, increased U.S. trade tariffs and trade disputes with other countries, supply chain weaknesses, instability in the global credit markets, severely diminished liquidity and credit availability, rising interest and inflation rates, declines in consumer confidence, declines in economic growth, increases in unemployment rates, uncertainty about economic stability, instability in the geopolitical environment, the Russian invasion of the Ukraine and other political tensions, including in the Middle East, and foreign governmental debt concerns. In 2023, the closures of Silicon Valley Bank, or SVB, and Signature Bank and their placement into receivership with the Federal Deposit Insurance Corporation, or the FDIC, created bank-specific and broader financial institution liquidity risk and concerns. Although the Department of the Treasury, the Federal Reserve, and the FDIC jointly released a statement that depositors at SVB and Signature Bank would have access to their funds, even those in excess of the standard FDIC insurance limits, under a systemic risk exception, future adverse developments with respect to specific financial institutions or the broader financial services industry may lead to market-wide liquidity shortages, impair the ability of market participants to access near-term working capital needs, and create additional market and economic uncertainty. There can be no assurance that any such continuing or future credit and financial market instability, liquidity shortages and a deterioration in confidence in economic conditions will not occur. Such challenges have caused, and may continue to cause, uncertainty and instability in local economies and in global financial markets, which could adversely affect our business, financial condition or results of operations. If these conditions continue to deteriorate or do not improve, it may make any necessary debt or equity financing more difficult to complete, more costly, and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance, and share price and could require us to delay or abandon development or commercialization plans. We do not carry insurance for all categories of risk that our business may encounter. There can be no assurance that we will secure adequate insurance coverage or that any such insurance coverage will be sufficient to protect us from potential liability in the future. Any significant uninsured liability may require us to pay substantial amounts, which may adversely affect our financial position and results of operations. We may be at risk of securities class action litigation. We may be at risk of securities class action litigation. In the past, biotechnology and pharmaceutical companies have experienced significant stock price volatility, particularly when associated with binary events such as clinical trials and product approvals. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business and results in a decline in the market price of our common stock. 75 Item 1B. Unresolved Staff Comments. None. Item 1C. Cybersecurity. Cybersecurity Risk Management We, like other companies in our industry, face several cybersecurity risks in connection with our business. Our business strategy, results of operations, and financial condition have not, to date, been affected by risks from cybersecurity threats. During the reporting period, we have not experienced any material cyber incidents, nor have we experienced a series of immaterial incidents, which would require disclosure. In the ordinary course of our business, we use, store and process data including data of our employees, partners, collaborators, and vendors. To effectively prevent, detect, and respond to cybersecurity threats, we maintain a cyber risk management program, which is comprised of a wide array of policies, standards, architecture, and processes. The cyber risk management program falls under the responsibility of our Director of IT & GxP Quality Systems, who has more than 15 years of experience, including cross-functional expertise in IT compliance and GXP systems. Under the guidance of our Director of IT & GxP Quality Systems, reporting up to our Chief Financial Officer, we develop, maintain, and evidence the policies, standards, and processes in a manner consistent with applicable legal requirements. We also utilize a variety of cybersecurity software from reputable vendors in cybersecurity. We have implemented a cybersecurity risk management program that is designed to identify, assess, and mitigate risks from cybersecurity threats to this data and our systems and ensure the effectiveness of our security controls. Our cybersecurity risk management program is Systems and Organization Controls (SOC)-certified and incorporates a number of components, including information security program assessments, continuous monitoring of critical risks from cybersecurity threats using automated tools, internal audits, and employee training. We deploy a wide range of security tools across the environment, require multifactor authentication, hold client data on a separate virtual private cloud (VPC), and implement access control policies that further limit access to data within the systems. We periodically conduct internal audits and are consistently evaluating our cyber readiness. As a result, we have not identified any material cybersecurity risks and are continuously hardening our environment, systems and infrastructure to reduce our vulnerability to attack. Additionally, our program includes regular cybersecurity training for all employees. For further information regarding cybersecurity risks, please refer to “Risk Factors – Risks Related to Development and Commercialization of Our Current and Future Product Candidates” and other risks described in the “Risk Factors” section of this Annual Report on Form 10-K. Governance Our board of directors is responsible for the oversight of cybersecurity risk management. The board of directors delegates oversight of the cybersecurity risk management program to the audit committee of the board of directors (the “Audit Committee”). Our Chief Financial Officer reports to the Audit Committee. The Audit Committee updates the board of directors on our cybersecurity risk management program, including any critical cybersecurity risks, ongoing cybersecurity initiatives and strategies, and applicable regulatory requirements and industry standards on an annual and as-needed basis. Item 2. Properties. Our principal offices are located at 3300 Bee Cave Road, #650-227, Austin, Texas 78746. We operate primarily as a virtual company, and we believe our current facilities and those that we believe are available to us are sufficient to meet our current needs and that suitable space will be available as and when needed. We do not own any real property. Item 3. Legal Proceedings. From time to time, we may be involved in legal proceedings that arise during the ordinary course of business. Although the results of legal proceedings cannot be predicted with certainty, we do not currently have any pending litigation to which we are a party or to which our property is subject that we believe to be material. Regardless of the outcome, litigation can be costly and time consuming, and it can divert management’s attention from important business matters and initiatives, negatively impacting our overall operations. Item 4. Mine Safety Disclosures. Not applicable. 76 Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities. Market Information PART II Our common stock began trading on The Nasdaq Capital Market under the symbol “GNPX” on March 29, 2018. Prior to that date, there was no public trading market for our common stock. Holders of Record As of March 25, 2024, there were approximately 158 stockholders of record of our common stock. The actual number of stockholders is greater than this number of record holders and includes stockholders who are beneficial owners but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust or by other entities. Dividend Policy We have never declared or paid cash dividends on our capital stock. We currently intend to retain all available funds and any future earnings for use in the operation of our business and do not anticipate paying any dividends on our common stock in the foreseeable future. Any future determination to declare dividends will be made at the discretion of our board of directors and will depend on, among other factors, our financial condition, operating results, capital requirements, contractual restrictions, general business conditions and other factors that our board of directors may deem relevant. Recent Sales of Unregistered Securities For the quarter ended December 31, 2023, we issued and sold the following unregistered securities: 1) On October 2, 2023, we issued an aggregate of 5,000 shares of our common stock to a consultant in consideration of services during the three months ended December 31, 2023. The foregoing issuance of securities was not registered under the Securities Act or the securities laws of any state, and the securities were offered and issued in reliance on the exemption from registration under the Securities Act afforded by Section 4(a)(2). During the year ended December 31, 2023, there were no other unregistered sales of our securities except as previously reported in a Current Report on Form 8-K or a Quarterly Report on Form 10-Q. Item 6. [Reserved] 77 Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. This Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) contains certain forward-looking statements. Historical results may not indicate future performance. Our forward-looking statements reflect our current views about future events, are based on assumptions and are subject to known and unknown risks and uncertainties that could cause actual results to differ materially from those contemplated by these statements. Factors that may cause differences between actual results and those contemplated by forward- looking statements include, but are not limited to, those discussed in “Risk Factors.” We undertake no obligation to publicly update or revise any forward-looking statements, including any changes that might result from any facts, events, or circumstances after the date hereof that may bear upon forward-looking statements. Furthermore, we cannot guarantee future results, events, levels of activity, performance, or achievements. All amounts in this report are in United States (“U.S.”) dollars, unless otherwise noted. Overview We are a clinical stage gene therapy company pioneering the development of gene-based therapies for large patient populations with unmet medical needs. Our oncology platform utilizes our systemic, non-viral ONCOPREX® Delivery System which uses lipid-based nanoparticles in a lipoplex form to deliver tumor suppressor gene-expressing plasmids to cancer cells. The product is administered intravenously, where it is taken up by tumor cells that then express tumor suppressor proteins that were deficient in the tumor. Our diabetes technology is designed to work in Type 1 diabetes by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In Type 2 diabetes, our technology is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin. Oncology Platform Our lead oncology drug candidate, REQORSA® Immunogene Therapy (generic name: quaratusugene ozeplasmid), previously referred to as GPX-001, is initially being developed in combination with prominent, approved cancer drugs to treat Non-Small Cell Lung Cancer (“NSCLC”) and Small Cell Lung Cancer (“SCLC”). REQORSA has a multimodal mechanism of action whereby it interrupts cell signaling pathways that cause replication and proliferation of cancer cells, re-establishes pathways for apoptosis, or programmed cell death, in cancer cells, and modulates the immune response against cancer cells. In early studies, REQORSA has been shown to be complementary with targeted drugs and immunotherapies. Our strategy is to develop REQORSA in combination with current approved therapies and we believe REQORSA’s unique attributes position it to provide treatments that improve on these current therapies for patients with NSCLC, SCLC, and possibly other cancers. Acclaim – 1: We currently are enrolling and treating patients in the Phase 2a expansion portion of our Phase 1/2 Acclaim-1 clinical trial. The Acclaim-1 trial uses a combination of REQORSA and AstraZeneca’s Tagrisso® in patients with late-stage NSCLC that has activating epidermal growth factor receptor (“EGFR”) mutations and progression after treatment with Tagrisso. Following the May 2023 completion of the Phase 1 dose escalation portion of the study, the Acclaim-1 Safety Review Committee (“Acclaim-1 SRC”) approved advancement from the Phase 1 dose escalation portion to the Phase 2a expansion portion of the study. Based on a review of safety data which showed no dose limiting toxicities (“DLTs”), the Acclaim-1 SRC determined that the recommended Phase 2 dose (“RP2D”) of REQORSA will be 0.12 mg/kg. This was the highest dose level delivered in the Phase 1 portion of the study and is twice the highest dose level delivered in the Company’s prior clinical trial combining REQORSA with Tarceva® for the treatment of late-stage lung cancer. We opened the Phase 2a expansion portion of the study and enrolled and dosed the first patient in January 2024. The Phase 2a expansion portion of the trial is expected to enroll approximately 66 patients; half will be patients who received only prior Tagrisso treatment and the other half will be patients who received prior Tagrisso treatment and chemotherapy. The aim is to determine toxicity and efficacy profiles of patients with different eligibility criteria. There will be an interim analysis following the treatment of 19 patients in each cohort. We expect to complete the enrollment of 19 patients in each cohort of the Phase 2a expansion portion of the study by the end of 2024, and thus we expect the interim analyses in early 2025. The Food and Drug Administration (“FDA”) has granted Fast Track Designation for the Acclaim-1 treatment combination of REQORSA and Tagrisso in NSCLC patients who have progressed after Tagrisso treatment. Acclaim – 2: We currently are enrolling and treating patients in the Phase 1 dose escalation portion of our Phase 1/2 Acclaim-2 clinical trial. The Acclaim-2 trial uses a combination of REQORSA and Merck & Co.’s Keytruda® in patients with late-stage NSCLC whose disease has progressed after treatment with Keytruda. Patients are currently being treated at the 0.06 mg/kg dose level in the first cohort of patients and, subject to Acclaim-2 Safety Review Committee (“Acclaim-2 SRC”) approval, will be treated at successive dose levels of 0.09 mg/kg and 0.12 mg/kg. In March 2023, we amended the Acclaim-2 protocol to include additional treatments in the control group with the goal of accelerating enrollment in the study by making the trial more attractive to a wider variety of investigators. We expect enrollment in the dose escalation portion of the study to be completed in the second half of 2024. We will then initiate and evaluate patients in the Phase 2a expansion portion of the study at the maximum tolerated dose (the “MTD”) or RP2D. The FDA has granted Fast Track Designation for the Acclaim-2 treatment combination of REQORSA and Keytruda in NSCLC patients who have progressed after Keytruda treatment. The expansion portion of both the Acclaim-1 and Acclaim-2 trials are Phase 2 studies. The expansion portion of these studies provides us the advantage of early insight into drug effectiveness in defined and distinct patient populations at the MTD or RP2D in order to better evaluate efficacy and increase the likelihood of a successful randomized Phase 2 trial which will follow the expansion portion of each study. 78 Acclaim – 3: We currently are enrolling patients in the Phase 1 dose escalation portion of our Phase 1/2 Acclaim-3 clinical trial. The Acclaim-3 clinical trial uses a combination of REQORSA and Genentech, Inc.’s Tecentriq® as maintenance therapy in patients with extensive stage small cell lung cancer (“ES-SCLC”) who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. Patients are treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. In January 2024, we opened the Phase 1 portion of the Acclaim-3 study for enrollment. We expect to complete the Phase 1 dose escalation portion of the study during the second half of 2024 and we expect to start the Phase 2 expansion portion of our Acclaim-3 study in the second half of 2024. In June 2023, the FDA granted Fast Track Designation for the Acclaim-3 treatment combination of REQORSA and Tecentriq as maintenance therapy in patients with ES-SCLC who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. In August 2023, the FDA granted Orphan Drug Designation to REQORSA for the treatment of SCLC. The TUSC2 gene, which is the key component of REQORSA and plays a vital role in cancer suppression and normal cell regulation, is one of a series of genes on the short arm of Chromosome 3 whose therapeutic use is covered by our exclusive worldwide licenses from The University of Texas MD Anderson Cancer Center (“MD Anderson”). We believe that our ONCOPREX Delivery System allows for delivery of a number of cancer-fighting genes, alone or in combination with other cancer therapies, to combat multiple types of cancer and we are in early stages of discovery programs to identify other cancer candidates. In August 2022, we entered into a three-year sponsored research agreement with MD Anderson to support further preclinical studies of TUSC2 and other tumor suppressor genes. Diabetes Gene Therapy In diabetes, we have exclusively licensed from the University of Pittsburgh of the Commonwealth System of Higher Education (“University of Pittsburgh”) multiple technologies relating to the development of a gene therapy product for each of Type 1 and Type 2 diabetes. The same general novel approach is used in each of Type 1 and Type 2 diabetes whereby an adeno-associated virus (“AAV”) vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. In humans, this can be done with a routine endoscopy procedure. Our diabetes product candidates are currently being evaluated and optimized in preclinical studies at the University of Pittsburgh. GPX-002 is being developed using the same construct for the treatment of both Type 1 diabetes and Type 2 diabetes. GPX-002 for Type 1 diabetes is designed to work by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In a similar approach, GPX-002 for Type 2 diabetes (formerly known as GPX-003), where autoimmunity is not at play, is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin. We finalized the components of the diabetes construct to take forward for nonclinical studies and in December 2023, we submitted a request to meet with the FDA to obtain their guidance on the nonclinical studies needed to file an Investigational New Drug (“IND”) application and initiate first-in-human studies. As a result of the FDA’s response, the Company will continue with its planned additional nonclinical studies before requesting regulatory guidance in 2024 for the IND-enabling studies. In October 2023, we entered into a one-year extension to our August 2022 sponsored research agreement with the University of Pittsburgh for the use of GPX-002 in a non-human primate (“NHP”) model in Type 2 diabetes. The extension includes a revised research plan to encompass our most recent technologies to which we acquired exclusive rights from the University of Pittsburgh in July 2023. These include a MafB promoter to drive expression of the Pdx1 and MafA transcription factors that can potentially be used for both Type 1 and Type 2 diabetes. See also “Note 7 – Commitments and Contingencies” to our financial statements included in this Annual Report on Form 10-K. In February 2023, the Company’s research collaborators at the University of Pittsburgh presented preclinical data in a NHP model of Type 1 diabetes highlighting the therapeutic potential of GPX-002 at the 16th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD 2023) in Berlin, Germany. The statistically significant study results showed the treated animals had decreased insulin requirements, increased c-peptide levels, and improved glucose tolerance compared to baseline. In April 2023, the Company hosted a Key Opinion Leader virtual event entitled “Novel Gene Therapy to Treat Type 1 Diabetes,” which discussed preclinical data reported at ATTD 2023 supporting gene therapy to treat Type 1 diabetes. Recently Issued Accounting Pronouncements A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 2 to our financial statements appearing in this Annual Report on Form 10-K. 79 Critical Accounting Policies and Significant Judgments and Estimates Our financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The preparation of these 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 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 we 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. We believe that the following accounting policies are the most critical to aid in fully understanding and evaluating our reported financial results, and they require our most difficult, subjective or complex judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain. Research and Development Costs We record accrued expenses for costs invoiced from research and development activities conducted on our behalf by third-party service providers, which include the conduct of preclinical studies and clinical trials and contract research, manufacturing, and testing activities. We record the costs of research and development activities based upon the amount of services provided, and we include these costs in accrued liabilities in the condensed balance sheets and within research and development expense in the condensed statements of operations. These costs are a significant component of our research and development expenses. Purchased materials to be used in future research are valued at cost and capitalized and included in research and development supplies. We estimate the amount of work completed through discussions with internal personnel and external service providers as to the progress or stage of completion of the services and the agreed-upon fee to be paid for such services. We make significant judgments and estimates in determining the accrued balance in each reporting period. As actual costs become known, we adjust our accrued estimates. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed, the number of patients enrolled and the rate of patient enrollment in any of our clinical trials may vary from our estimates and could result in our reporting amounts that are too high or too low in any particular period. Our accrued expenses are dependent, in part, upon the receipt of timely and accurate reporting from contract research organizations (“CROs”) and other third-party service providers. Income Taxes Deferred tax assets or liabilities are recorded for temporary differences between financial statement and tax basis of assets and liabilities, using applicable rates in effect for the year in which the differences are expected to reverse. A valuation allowance is recorded if it is more likely than not that a deferred tax asset will not be realized. We have provided a full valuation allowance on our deferred tax assets, which primarily consist of cumulative net operating losses from April 1, 2009 (inception) to December 31, 2023. Due to our history of operating losses since inception and losses expected to be incurred in the foreseeable future, a full valuation allowance was considered necessary. Impairment of Long-Lived Assets Management reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be realizable or at a minimum annually during the fourth quarter of the year. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset’s carrying value to determine if an impairment of such asset is necessary. The effect of any impairment would be to expense the difference between the fair value of such asset and its carrying value. 80 Components of our Results of Operations and Financial Condition Operating expenses We classify our operating expenses into three categories: research and development, general and administrative, and depreciation. Research and development. Research and development expenses consist primarily of: ● ● ● ● ● ● costs incurred to conduct research, such as the discovery and development of our current and potential product candidates; costs related to the production and storage of supplies for engineering purposes and storage and usage of clinical supplies, including waste created in the process of producing clinical materials, spoilage, and testing of clinical materials; costs related to the use of contract manufacturers, manufacturing consultants, testing organizations, cold-storage facilities, and logistics service providers; fees paid to clinical consultants, clinical trial sites and vendors, including CROs in conjunction with implementing and monitoring our clinical trials and acquiring and evaluating clinical trial data, including all related fees, such as patient screening fees, laboratory work, and statistical compilation and analysis; costs related to compliance with drug development regulatory requirements; and costs related to staffing and personnel associated with research and development activities, including wages, taxes, benefits, leases, overheads, supplies, and share- based compensation. We recognize all research and development costs as they are incurred. Clinical trial costs, contract manufacturing and other development costs incurred by third parties are expensed as the contracted work is performed. We expect our research and development expenses to increase in the future as we (i) continue to advance our current and future product candidates into and through clinical trials, (ii) transition some of our manufacturing activities to new vendors for a variety of reasons, such as to incorporate more advanced processes and scale production, including any additional work that has been or may be required to successfully adapt our process to these new processes, (iii) pursue regulatory approval of our current and potential product candidates in the United States and Europe, and (iv) expand our research programs to include new therapies and new therapy combinations. The process of conducting the necessary preclinical and clinical research to obtain regulatory approval is costly and time-consuming. The actual probability of success for our current and potential product candidates may be affected by a variety of factors including the quality of our current and potential product candidates, early clinical data, investment in our clinical program, competition, manufacturing capability and commercial viability, and limited contracted partners. We may never succeed in achieving regulatory approval for any of our current or future product candidates. As a result of the uncertainties discussed above, we are unable to determine the duration and completion costs of our research and development projects or when and to what extent we will generate revenue from the commercialization and sale of our product candidates, if at all. General and administrative. General and administrative expense consists of personnel related costs, which include salaries, as well as the costs of professional services, such as accounting and legal, travel, facilities, information technology and other administrative expenses. We expect our general and administrative expense to increase in future periods due to the anticipated growth of our business and related infrastructure as well as accounting, insurance, investor relations, legal, information technology, and other costs associated with being a public company. Depreciation. Depreciation expense consists of depreciation from our fixed assets consisting of our property, equipment, and furniture. We depreciate our assets over their estimated useful life. We estimate furniture and computer and office equipment to have a five-year life. 81 Results of Operations Comparison of the Years Ended December 31, 2023 and 2022 The following summarizes our results of operations for the years ended December 31, 2023 and 2022. Research and Development Expense. Research and development (“R&D”) expense was $17,616,605 for the year ended December 31, 2023 as compared to $11,510,074 for the year ended December 31, 2022. This increase of $6,106,531, or 53%, is primarily due to (i) changes in our manufacturing programs due to our transition to more capable contract development and manufacturing organizations (“CDMOs”), (ii) increased manufacturing and testing of our drug product for our Acclaim-1 and Acclaim-2 clinical trials, and (iii) increase in third-party vendors to support our manufacturing and preclinical and clinical programs. General and Administrative Expense. General and administrative (“G&A”) expense for the year ended December 31, 2023 was $13,443,961 as compared to $12,295,070 for the year ended December 31, 2022. The increase of $1,148,891, or 9% is primarily due to (i) an increase in professional services and third-party vendors to support corporate programs, and (ii) greater share-based compensation associated with G&A employees and service providers. Interest Income. Interest income was $215,109 and $90,098 for the years ended December 31, 2023 and 2022, respectively. This increase of $125,011 was primarily due to changes in balances and a significant increase in interest rates of our money market instruments for the year ended December 31, 2023 as compared to the prior year. Interest Expense. There was no interest expense for the years ended December 31, 2023 and 2022 because we had no debt obligations. As of December 31, 2023, we had no outstanding debt. Depreciation Expense. Depreciation expense was $15,004 and $25,575 for the years ended December 31, 2023 and 2022, respectively. The decrease of $10,571, or 41%, in depreciation was primarily due to the timing of purchases of computer equipment for new employees. Net Loss. We had a net loss of $30,860,461, for the fiscal year ended December 31, 2023 compared to a net loss of $23,740,621 for the fiscal year ended December 31, 2022. The increase of $7,119,840, or 30%, in net loss was primarily due to the expansion of our manufacturing to more qualified CDMOs as well as increased manufacturing and testing of our drug product to support our Acclaim-1 and Acclaim-2 clinical trials. 82 Liquidity and Capital Resources From inception through December 31, 2023, we have never generated revenue from product sales and have incurred net losses in each year. As of December 31, 2023, we had an accumulated deficit of $133,688,280. We have funded our operations primarily through the sale and issuance of capital stock. For the year ended December 31, 2022, we sold an aggregate of 98 shares of common stock for total net proceeds of $4,532 pursuant to our 2022 ATM facility as governed by the Equity Distribution Agreement (as further described below) and issued 2,925 shares of common stock upon the exercise of options for gross proceeds of $1,755. For the year ended December 31, 2023, we sold an aggregate of 1,342 shares of common stock for total net proceeds of $78,355 pursuant to our 2022 ATM facility as governed by the Equity Distribution Agreement (as further described below). On November 18, 2022, we entered into an Equity Distribution Agreement with JMP Securities, with respect to an at-the-market offering program (our “2022 ATM Facility”) under which we could offer and sell, from time to time at our sole discretion, shares of our common stock, having an aggregate offering price of up to $50.0 million. We agreed to pay JMP Securities a commission equal to three percent (3%) of the gross sales proceeds of any shares sold under the Equity Distribution Agreement, and also provided JMP Securities with customary indemnification and contribution rights. For the year ended December 31, 2022, we sold 98 shares of our common stock for net proceeds to us totaling $4,532. For the year ended December 31, 2022, we sold 1,342 shares of our common stock for net proceeds to us totaling $78,355. On December 12, 2023, we provided notice to JMP Securities of our termination of the 2022 ATM Facility. The termination of the Equity Distribution Agreement with JMP Securities was effective as of December 13, 2023. On March 1, 2023, we completed a registered direct offering in which we sold 95,239 shares of our common stock and warrants to purchase 95,239 shares of our common stock to an accredited healthcare-focused institutional investor for aggregate net proceeds of approximately $3.6 million. On July 21, 2023, we raised approximately $6.7 million in net proceeds in a registered direct offering pursuant to which we sold 185,644 shares of common stock and warrants to purchase up to 185,644 shares of common stock. On December 13, 2023, we entered into an At The Market (“ATM”) Offering Agreement (the “Agreement”) with H.C. Wainwright & Co., LLC, serving as agent (the “Agent”) with respect to an at-the-market offering program under which we may offer and sell through the Agent, from time to time at our sole discretion, up to such number or dollar amount of shares of our common stock (the “Shares”) as registered on the prospectus supplement covering the ATM offering, as may be amended or supplemented from time to time. We have agreed to pay the Agent a commission equal to three percent (3%) of the gross sales proceeds of any Shares sold through the Agent under the Agreement, and also have provided the Agent with customary indemnification and contribution rights. As of December 31, 2023 we had not sold any Shares through the Agent under the Agreement. From January 1, 2024 through the date of filing of this Annual Report on Form 10-K, subsequent to the December 31, 2023 balance sheet date, we have sold 158,474 Shares for net proceeds to us totaling $881,946 through the Agent under the Agreement. As of December 31, 2023, we had $6,737,629 in cash. Subsequent to year-end 2023, on March 21, 2024, we raised approximately $5.8 million in net proceeds in a registered direct offering pursuant to which we sold (i) 165,000 shares of our common stock, (ii) pre-funded warrants exercisable for up to an aggregate of 1,377,112 shares of our common stock, and (iii) warrants exercisable for up to an aggregate of 1,542,112 shares of our common stock. In connection with the March 2024 registered direct offering, we amended certain existing warrants to reduce the exercise price and extend the term thereof. See “Note 9 – Subsequent Events – March 2024 Registered Direct Offering” to the Financial Statements included in this Annual Report on Form 10-K. Additionally, as noted above, we received net proceeds totaling $881,946 through the Agent under the ATM Agreement subsequent to year-end 2023. We do not expect to generate revenue from product sales unless and until we successfully complete development of, obtain regulatory approval for and begin to commercialize one or more of our current or potential product candidates, which we expect will take a number of years and which is subject to significant uncertainty. Accordingly, we anticipate that we will need to raise additional capital to fund our future operations, which include conducting our Acclaim-1, Acclaim-2, and Acclaim-3 clinical trials (of which Acclaim-1, Acclaim-2 and Acclaim-3 are currently enrolling) and completing preclinical work for potential other oncology candidates and completing preclinical work and conducting clinical trials for our diabetes program. We expect enrollment in each of the cohorts of the Phase 2a expansion portion of the Acclaim-1 trial to be completed by the end of 2024. We expect enrollment in the Phase 1 dose escalation portion of the Acclaim-2 trial to be completed by the second half of 2024. Enrollment in the Acclaim-3 clinical trial is expected to be completed during the second half of 2024 after which we expect to commence the Phase 2 portion of the Acclaim-3 trial in the second half of 2024. Until such time as we can generate substantial revenue from product sales, if ever, we expect to finance our operating activities through a combination of equity offerings, drawdowns on our ATM pursuant to our Agreement with the Agent, and debt financings and we may seek to raise additional capital through strategic collaborations or transactions. However, we may be unable to raise additional funds or enter into such arrangements when needed on favorable terms, or at all, which would have a negative impact on our financial condition and could force us to delay, limit, reduce or terminate our research and development programs or commercialization efforts or grant rights to others to develop or market product candidates that we would otherwise prefer to develop and market ourselves. Failure to receive additional funding could cause us to curtail or cease our operations. Furthermore, even if we believe we have sufficient funds for our current or future operating plans, we may seek additional capital due to favorable market conditions or strategic considerations. Based on our current cash, we estimate that we will be able to fund our expenditure requirements for our current operations and planned clinical trial activities into the third quarter of 2024. We have based these estimates on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently plan due to incorrect assumptions or due to a decision to expand our activities beyond those currently planned. We previously have experienced delays in engaging clinical sites as a result of disruptions at these clinical sites caused by the COVID-19 pandemic. We also have experienced delays in clinical trial enrollment as a result of competition for patients and additional time required in connection with our transition to the new third party CDMO and the manufacture of final drug product. Delays in the conduct of our trials could result in utilizing our capital resources sooner without advancing our clinical trials as anticipated. The following table sets forth the primary sources and uses of cash for the years ended December 31, 2023 and 2022: Net cash used in operating activities Net cash used in investing activities Net cash provided by financing activities Net decrease in cash 83 $ Years Ended December 31, 2022 2023 (17,621,498) (24,738,603) (59,735) (71,214) 10,593,377 6,426 (17,674,807) (14,216,440) $ Short Term Cash Requirements We believe that our existing cash is sufficient to fund our expected short-term needs into the third quarter of 2024, but will need additional fundraising activities and cash on hand by such time. We currently have certain fixed cash obligations with respect to development of materials used in our clinical studies and payment obligations associated with our ongoing conduct and monitoring of our Acclaim clinical trials, and we expect that we will have insufficient cash to cover these requirements through fiscal year 2024 without raising additional working capital. The foregoing conditions raise substantial doubt regarding our ability to continue as a going concern for a period of one year after the date the financial statements included in this Annual Report are issued. Lack of necessary funds may require us, among other things, to delay, scale back or eliminate some or all of our ongoing and/or planned clinical trials. Long Term Cash Requirements We regularly evaluate our business plans and strategy. These evaluations often result in changes to our business plans and strategy, some of which may be material and significantly change our cash requirements. Ongoing business development activity may require us to use some of our liquidity for an acquisition, or additional capital to fund newly acquired operations. If we raise additional funds by issuing equity securities, our existing security holders will likely experience dilution; and the incurring of indebtedness would result in increased debt service obligations and could require us to agree to operating and financial covenants that could restrict operations. ● ● ● ● ● ● ● ● Our future capital requirements depend on many factors, including, but not limited to: the costs and timing of our development activities and preclinical and clinical trials; the cost of manufacturing our existing and future products; the expenses needed to attract and retain skilled personnel; the costs associated with being a public company; the costs associated with additional business development or mergers and acquisitions activity, including acquisition-related costs, earn-outs or other contingent payments and costs of developing and commercializing any technologies to which we obtain rights; third-party costs associated with the development and commercialization of our existing and future products and the ability of our development partners to satisfy our requirements on a timely basis; the scope and terms of our business plans from time to time, and our ability to realize upon our business plans; and the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing possible patent claims, including litigation costs and the outcome of any such litigation. 84 Cash used in operating activities Net cash used in operating activities was $24,738,603 and $17,621,498 for the years ended December 31, 2023 and 2022, respectively. The increase of $7,117,105, or 40%, in net cash used in operating activities in 2023 was primarily due to us advancing our manufacturing programs to support enrollment of patients in our Acclaim-1 and Acclaim-2 clinical trials in the year ended December 31, 2023 compared to December 31, 2022 when our Acclaim-1 and Acclaim-2 clinical trials were initiated but enrolling patients at the slower, safety-oriented, Phase 1 portion per their respective protocols. Cash used in investing activities Net cash used in investing activities was $71,214 and $59,735 for the years ended December 31, 2023 and 2022, respectively. The increase in net cash provided by investing activities of $11,479, or 19%, was primarily due to greater use of R&D materials associated with testing and clinical use in our Acclaim clinical trials in the year ended December 31, 2023 compared to the year ended December 31, 2022. Changes in intellectual property and research and development supplies during this period were negligible. Cash provided by financing activities Net cash provided by financing activities was $10,593,377 and $6,426 for the years ended December 31, 2023 and 2022, respectively. The increase of $10,586,951, or 100%, in net cash provided by financing activities was primarily due to the registered direct offerings in February 2023 and July 2023 and there were no comparable capital raising activities throughout the year ended December 31, 2022. Item 7A. Quantitative and Qualitative Disclosures About Market Risk. As a smaller reporting company, we are not required to provide the information called for by this item. Item 8. Financial Statements and Supplementary Data. The financial statements and supplementary data required by this item are included after Part IV of this Annual Report on Form 10-K beginning on page F-1. Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure. Not applicable. 85 Item 9A. Controls and Procedures. Evaluation of Disclosure Controls and Procedures As required by Rules 13a-15(b) and 15d-15(b) of the Exchange Act, our management with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2023. The term “disclosure controls and procedures” as defined in Rules 13a-15(e) and 15d- 15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to a company’s management, including its principal executive and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2023, our Chief Executive Officer and our Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were not effective due to material weaknesses in our internal control over financial reporting related to a lack of segregation of duties between accounting and other functions and the absence of sufficient depth of in-house accounting personnel with the ability to properly account for complex transactions. Management’s Report on Internal Control over Financial Reporting Our principal executive officer and our principal accounting and financial officer are responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Management conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2023. In making this assessment, management used the criteria described in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our management concluded that our internal controls over financial reporting were, and continue to be, ineffective as of December 31, 2023 due to material weaknesses in our internal controls due to the lack of segregation of duties and insufficient depth of in-house accounting personnel. It should be noted that any system of controls, however well designed and operated, can provide only reasonable and not absolute assurance that the objectives of the system are met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of certain events. Because of these and other inherent limitations of control systems, there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. In light of the material weakness described below, we performed additional analysis and other post-closing procedures to ensure our financial statements were prepared in accordance with generally accepted accounting principles. Accordingly, we believe that the financial statements included in this report fairly present, in all material respects, our financial condition, results of operations and cash flows for the periods presented. During the year ended December 31, 2023 and as our operational activities increased, management determined and continues to determine that it does not have sufficient segregation of duties within its accounting functions nor does it have sufficient depth of in-house accounting personnel with the ability to properly account for complex transactions, which are basic internal controls. Due to our size, segregation of all conflicting duties may not always be possible and may not be economically feasible. However, to the extent possible, the initiation of transactions, the custody of assets and the recording of transactions should be performed by separate individuals. Our size and nature also do not allow for our accounting staff to have depth of expertise in all areas that might be desirable, such as expertise in accounting for a variety of complex transactions. Management evaluated the impact of our failure to maintain effective segregation of duties and sufficient depth of personnel on our assessment of our internal control over financial reporting and has concluded that these control deficiencies represent material weaknesses. 86 Remediation Plans Management is actively engaged in remediation efforts to address the material weakness identified in the management’s evaluation of internal controls and procedures. The remediation efforts, which have been or are in the process of being implemented, are intended to address the identified material weakness and include: ● ● ● ● ● ● new accounting software, processes, and workflows to further segregate duties among limited accounting staff; specific review procedures, including the added involvement of our General Counsel to review all accounting transactions following a given period in an effort to enhance accuracy of reporting; specific review procedures, including the added involvement of our manufacturing staff, to enhance controls associated with the tracking and reporting of inventory values in our supply chain; a formal Disclosure Committee that has oversight responsibility for the accuracy and timeliness of disclosures made by the Company through controls and procedures and the monitoring of their integrity and effectiveness; additional hiring of staff and development of accounting processes and policies to further segregate accounting responsibilities and increase the depth of our expertise in accounting for a variety of complex transactions; and additional training, testing, and certification of key accounting, finance, IT, and legal team members. continued evaluation and documentation of policies, processes, and controls, both manual and automated; During the year ended December 31, 2023, we took actions to remediate the material weakness relating to our internal controls over financial reporting including: ● ● ● identification and implementation of improvements to information technology and security controls and supporting control documentation; improvements to software workflows to further segregate duties, enhance accuracy of vendor billing, and ensure transparency and oversight from vendor or project managers, department leaders, legal team members, and finance team members; ● ● ● ● initiation and completion of training programs, testing, and certification for key accounting and finance personnel related to internal controls and implementation of COSO Framework; evaluation of existing capabilities of accounting and finance staff related to complex technical accounting items associated with U.S. GAAP and engagement with external advisory firms to provide technical support as necessary; the hiring of a director-level IT employee specialized in the evaluation and implementation of IT and secure policies, processes, and control documentation, and evaluation of inventory management and quality management software systems and associated implementation to ensure effective workflow processes and effective control environment of these systems; and the hiring and integration of an associate general counsel with SEC reporting experience into our internal controls over financial reporting process to assist in the review and oversight of financial reporting and disclosure controls. As management continues to evaluate and work to improve its internal control over financial reporting, we may take additional measures to address control deficiencies, or we may modify certain of the remediation measures described above. While remediation efforts are active, management requires additional time to demonstrate the operating effectiveness of our remediation efforts. The material weaknesses cannot be considered remediated until the applicable remedial controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. Changes in Internal Control over Financial Reporting There were no changes in our internal control over financial reporting during the year ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Inherent Limitations of Disclosure Controls and Internal Control over Financial Reporting Because of their inherent limitations, our disclosure controls and procedures and our internal control over financial reporting may not prevent material errors or fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to risks, including that the controls may become inadequate because of changes in conditions or that the degree of compliance with our policies or procedures may deteriorate.

INDEX TO FINANCIAL STATEMENTS Report of Independent Registered Public Accounting Firm (Auditor ID # 100) Report of Independent Registered Public Accounting Firm (Auditor ID # 0229) Balance Sheets - December 31, 2023 and 2022 Statements of Operations - December 31, 2023 and 2022 Statements of Changes in Stockholders’ Equity - December 31, 2023 and 2022 Statements of Cash Flows - December 31, 2023 and 2022 Notes to Financial Statements F-1 F-2 F-3 F-5 F-6 F-7 F-8 F-9 Report of Independent Registered Public Accounting Firm To the Board of Directors and Stockholders of Genprex, Inc.: Opinion on the Financial Statements We have audited the accompanying balance sheet of Genprex, Inc. (the “Company”) as of December 31, 2023, and the related statements of operations, changes in stockholders’ equity, and cash flows for the year then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the 2023 financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America. Substantial Doubt Regarding Going Concern The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the financial statements, the Company has an accumulated deficit at December 31, 2023 and, since inception, has suffered significant operating losses and negative cash flows from operations that raise substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. Revisions to 2022 Financial Statements The financial statements of the Company as of and for the year ended December 31, 2022, before the effects of the adjustments to retrospectively apply the change in accounting related to the reverse stock split described in Notes 2 and 4 to the financial statements, were audited by other auditors whose report, dated March 31, 2023, expressed an unqualified opinion on those statements. We audited the adjustments to the 2022 financial statements to retrospectively apply the February 2, 2024, reverse stock split, as described in Notes 2 and 4 to the financial statements. In our opinion, such retrospective adjustments are appropriate and have been properly applied. However, we were not engaged to audit, review, or apply any other procedures to the 2022 financial statements of the Company other than with respect to the retrospective adjustments and procedures related to certain state and federal tax information as described in the following paragraph and, accordingly, we do not express an opinion or any other form of assurance on the 2022 financial statements taken as a whole. The financial statements of the Company as of and for the year ended December 31, 2022, excluding the tabular federal and state income tax information for the 2022 financial statements disclosed in Note 8, were audited by other auditors whose report, dated March 31, 2023, expressed an unqualified opinion on those statements. We audited the tabular federal and state income tax information for the 2022 financial statements disclosed in Note 8. In our opinion, such information included in the table for 2022 is fairly stated, in all material respects, as of and for the year ended December 31, 2022. However, we were not engaged to audit, review, or apply any other procedures to the 2022 financial statements of the Company other than with respect to the tabular federal and state income tax information for the 2022 financial statements disclosed in Note 8 and procedures related to retroactive adjustments as a result of the reverse stock split as described in the preceding paragraph, and, accordingly, we do not express an opinion or any other form of assurance on the 2022 financial statements taken as a whole. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit. 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit 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 audit 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 entity’s internal control over financial reporting. Accordingly, we express no such opinion. Our audit 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 included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit 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 audit provides a reasonable basis for our opinion. Critical Audit Matters The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate opinion on the critical audit matters or on the accounts or disclosures to which they relate. F-2 Accounting for Accrued Research and Development Costs Critical Audit Matter Description The Company records accrued expenses for estimated costs of research and development activities conducted by third-party service providers, which include the conduct of preclinical studies and clinical trials, and contract manufacturing activities. The Company records the estimated costs of research and development activities based upon the estimated amount of services provided and include the costs incurred but not yet invoiced within other accrued liabilities in the balance sheet and within research and development expense in the statement of operations. These costs can be a significant component of the Company’s research and development expenses. The Company estimates the amount of work completed through discussions with internal personnel and external service providers as to the progress of the services and the agreed- upon fee to be paid for such services. The Company makes estimates in determining the accrued balance in each reporting period. Clinical trial related contracts vary in duration, and may be for a fixed amount, based on the achievement of certain contingent events or deliverables, a variable amount based on actual costs incurred, capped at a certain limit or contain a combination of these elements. Estimates include costs associated with services provided by contract organizations for preclinical and clinical development, and manufacturing of the Company’s product candidates. In the case of clinical trials, the Company relies on estimates of the progress of the clinical trials and related expenses incurred. As actual costs become known, the Company adjusts its accrued estimates. We identified accrued research and development costs as a critical audit matter given the estimation involved in accounting for accrued research and development costs, as well as the material weakness identified by the Company in its internal controls over financial reporting. This required extensive audit effort related to the estimation of accrued research and development costs. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to accrued research and development costs included the following, among others: we obtained an understanding and evaluated the design and implementation of controls over the estimation of accrued preclinical studies, clinical trials and manufacturing expenses. We also read a sample of research, collaboration, and manufacturing agreements and contracts, as well as amendments thereto. We also evaluated publicly available information (such as press releases and investor presentations) and board of directors’ materials regarding the status of preclinical studies, clinical trial and manufacturing activities. For a selection of agreements and contracts, we compared the amount of accrual at the end of the prior period to current year activity and evaluated the accuracy of the Company’s estimation methodology. For the selection of agreements, we obtained a written confirmation of the status of clinical trials and manufacturing from the Company’s third-party service providers. We also made selections of specific amounts recognized as research and development expense as well as those recognized as accrued expenses to evaluate management’s estimate of the vendor’s progress and performed additional procedures. Accounting for Equity Financing and Warrant Issuances Critical Audit Matter Description The Company evaluates its equity issuances to determine if those contracts or embedded components of those contracts qualify as derivative instruments requiring separate recognition in the Company’s financial statements. As described in Note 4, on March 1, 2023, the Company completed a registered direct offering (“RDOs”), in which the Company sold to an accredited healthcare-focused institutional investor an aggregate of 95,239 shares of its common stock and warrants to purchase up to 95,239 shares of its common stock, at a combined offering price of $42.00 per share of common stock and accompanying warrant. On July 21, 2023, the Company completed another registered direct offering priced at the market under Nasdaq rules, in which the Company sold to accredited healthcare-focused institutional investors an aggregate of (i) 185,644 shares of its common stock, and (ii) warrants to purchase up to 185,644 shares of its common stock, at a combined offering price of $40.40 per share of common stock and accompanying warrant. Also, the Company agreed to issue to the Placement Agent warrants to purchase up to an aggregate of 11,140 shares of the Company’s common stock. We identified the accounting for equity financing and warrant issuances as a critical audit matter because of the complexity in applying the accounting framework, as well as the material weakness identified by the Company in its internal controls over financial reporting. This required extensive audit effort related to application of accounting framework. How the Critical Audit Matter Was Addressed in the Audit Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the financial statements. These procedures included, among others, obtaining an understanding of, evaluating the design of the operating effectiveness of controls over management’s process for the accounting treatment, reading the agreements, and evaluating the accounting for the RDO warrant issuance. Testing management’s process included (i) evaluating the internal controls and application of the accounting framework used by management; (ii) testing the mathematical accuracy of management’s calculations; and (iii) testing the completeness and accuracy of the underlying data used. Professionals with specialized skill and knowledge were used to assist in (i) evaluating management’s application of the accounting framework and (ii) testing the mathematical accuracy of management’s calculation and conclusion related to the accounting classification of the 2023 RDO warrant issuances. /s/ WithumSmith+Brown, PC We have served as the Company’s auditor since 2023. East Brunswick, New Jersey April 1, 2024 PCAOB ID Number 100 F-3 Report of Independent Registered Public Accounting Firm To the Board of Directors and Stockholders of Genprex, Inc. Austin, Texas Opinion on the Financial Statements We have audited, before (1) the effects of the adjustments to retrospectively apply the effects of the reverse stock split described in Note 2 – Summary of Significant Accounting Policies – Reverse Stock Split and Note 4 – Equity – Reverse Stock Split (Reverse Stock Split) and (2) the inclusion of tabular federal and state income tax information for the 2022 financial statements disclosed in Note 8 – Income Taxes, the accompanying balance sheet of Genprex, Inc. (the “Company”) at December 31, 2022, and the related statements of operations, changes in stockholders’ equity, and cash flows for the year ended December 31, 2022, and the related notes (collectively referred to as the financial statements). In our opinion, before (1) the effects of the adjustments to retrospectively apply the reverse stock split described in Note 2 – Summary of Significant Accounting Policies – Reverse Stock Split and Note 4 – Equity – Reverse Stock Split (Reverse Stock Split) and (2) the inclusion of tabular federal and state income tax information for the 2022 financial statements disclosed in Note 8 – Income Taxes, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022, and the results of its operations and its cash flows for the year ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America. 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 audit. 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit 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 audit 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 included 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 audit provides a reasonable basis for our opinion. Critical Audit Matters The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as whole, and we are not, by communicating the critical matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate. Valuation of equity transactions As described in the Equity Note to the financial statements, the Company has complex equity transactions including the use of stock options and warrants. The estimates that management used in calculating the price value depend on assumptions specific to the nature of the management service activities with regard to the amount of the price model. The principal consideration for our determination surrounding equity transactions as a critical audit matter is the significant judgment by management when developing the valuation of options and warrants. This, in turn, led to a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to the price model used to calculate equity transactions. Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the financial statements. These procedures included evaluating the use of the fair value-based method of accounting for stock-based compensation for options granted to employees, independent consultants and contractors. The Company measures options granted at fair value determined as of the grant date, and recognizes the expense over the periods in which the related services are rendered based on the terms and conditions of the awards. Evaluation of management’s assumptions related to the price model and evaluating whether assumptions used by management were reasonable considering the current and past performance of equity, the consistency, and whether these assumptions were consistent with evidence obtained in other areas of the audit. /s/ Daszkal Bolton LLP We served as the Company’s auditor from 2014 through March 2023.

Notes to Financial Statements Note 1 – Description of Business and Basis of Presentation Genprex, Inc. (“Genprex” or the “Company”), incorporated in Delaware in April 2008, is a clinical stage gene therapy company pioneering the development of gene-based therapies for large patient populations with unmet medical needs. The Company’s oncology platform utilizes its systemic, non-viral ONCOPREX® Delivery System which uses lipid-based nanoparticles in a lipoplex form to deliver tumor suppressor gene-expressing plasmids to cancer cells. The product is administered intravenously, where it is taken up by tumor cells that then express tumor suppressor proteins that were deficient in the tumor. The Company’s diabetes technology is designed to work in Type 1 diabetes by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In Type 2 diabetes, the Company’s technology is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin. Oncology Platform Genprex’s lead oncology drug candidate, REQORSA® Immunogene Therapy (generic name: quaratusugene ozeplasmid), previously referred to as GPX-001, is initially being developed in combination with prominent, approved cancer drugs to treat Non-Small Cell Lung Cancer (“NSCLC”) and Small Cell Lung Cancer (“SCLC”). REQORSA has a multimodal mechanism of action whereby it interrupts cell signaling pathways that cause replication and proliferation of cancer cells, re-establishes pathways for apoptosis, or programmed cell death, in cancer cells, and modulates the immune response against cancer cells. In early studies, REQORSA has been shown to be complementary with targeted drugs and immunotherapies. The Company’s strategy is to develop REQORSA in combination with current approved therapies and the Company believes REQORSA’s unique attributes position it to provide treatments that improve on these current therapies for patients with NSCLC, SCLC, and possibly other cancers. Acclaim – 1: The Company is currently enrolling and treating patients in the Phase 2a expansion portion of its Phase 1/2 Acclaim-1 clinical trial. The Acclaim-1 trial uses a combination of REQORSA and AstraZeneca’s Tagrisso® in patients with late-stage NSCLC that has activating epidermal growth factor receptor (“EGFR”) mutations and progression after treatment with Tagrisso. Following the May 2023 completion of the Phase 1 dose escalation portion of the study, the Acclaim-1 Safety Review Committee (“Acclaim-1 SRC”) approved advancement from the Phase 1 dose escalation portion to the Phase 2a expansion portion of the study. Based on a review of safety data which showed no dose limiting toxicities (“DLTs”), the Acclaim-1 SRC determined that the recommended Phase 2 dose (“RP2D”) of REQORSA will be 0.12 mg/kg. This was the highest dose level delivered in the Phase 1 portion of the study and is twice the highest dose level delivered in the Company’s prior clinical trial combining REQORSA with Tarceva® for the treatment of late-stage lung cancer. Genprex opened the Phase 2a expansion portion of the study and enrolled and dosed the first patient in January 2024. The Phase 2a expansion portion of the trial is expected to enroll approximately 66 patients; half will be patients who received only prior Tagrisso treatment and the other half will be patients who received prior Tagrisso treatment and chemotherapy. The aim is to determine toxicity and efficacy profiles of patients with different eligibility criteria. There will be an interim analysis following the treatment of 19 patients in each cohort. The Company expects to complete the enrollment of 19 patients in each cohort of the Phase 2a expansion portion of the study by the end of 2024, and thus the Company expects the interim analyses in early 2025. The Food and Drug Administration (“FDA”) has granted Fast Track Designation for the Acclaim-1 treatment combination of REQORSA and Tagrisso in NSCLC patients who have progressed after Tagrisso treatment. Acclaim – 2: The Company is currently enrolling and treating patients in the Phase 1 dose escalation portion of its Phase 1/2 Acclaim-2 clinical trial. The Acclaim-2 trial uses a combination of REQORSA and Merck & Co.’s Keytruda® in patients with late-stage NSCLC whose disease has progressed after treatment with Keytruda. Patients are currently being treated at the 0.06 mg/kg dose level in the first cohort of patients and, subject to Acclaim-2 Safety Review Committee (“Acclaim-2 SRC”) approval, will be treated at successive dose levels of 0.09 mg/kg and 0.12 mg/kg. In March 2023, Genprex amended the Acclaim-2 protocol to include additional treatments in the control group with the goal of accelerating enrollment in the study by making the trial more attractive to a wider variety of investigators. The Company expects enrollment in the dose escalation portion of the study to be completed in the second half of 2024. The Company will then initiate and evaluate patients in the Phase 2a expansion portion of the study at the maximum tolerated dose (the “MTD”) or RP2D. The FDA has granted Fast Track Designation for the Acclaim-2 treatment combination of REQORSA and Keytruda in NSCLC patients who have progressed after Keytruda treatment. The expansion portion of both the Acclaim-1 and Acclaim-2 trials are Phase 2 studies. The expansion portion of these studies provides the Company with the advantage of early insight into drug effectiveness in defined and distinct patient populations at the MTD or RP2D in order to better evaluate efficacy and increase the likelihood of a successful randomized Phase 2 trial which will follow the expansion portion of each study. Acclaim – 3: The Company is currently enrolling patients in the Phase 1 dose escalation portion of its Phase 1/2 Acclaim- 3 clinical trial. The Acclaim- 3 clinical trial uses a combination of REQORSA and Genentech, Inc.’s Tecentriq® as maintenance therapy in patients with extensive stage small cell lung cancer (“ES-SCLC”) who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. Patients are treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. In January 2024, the Company opened the Phase 1 portion of the Acclaim- 3 study for enrollment. The Company expects to complete the Phase 1 dose escalation portion of the study during the second half of 2024 and the Company expects to start the Phase 2 expansion portion of its Acclaim- 3 study in the second half of 2024. In June 2023, the FDA granted Fast Track Designation for the Acclaim- 3 treatment combination of REQORSA and Tecentriq as maintenance therapy in patients with ES- SCLC who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. In August 2023, the FDA granted Orphan Drug Designation to REQORSA for the treatment of SCLC. The TUSC2 gene, which is the key component of REQORSA and plays a vital role in cancer suppression and normal cell regulation, is one of a series of genes on the short arm of Chromosome 3 whose therapeutic use is covered by the Company’s exclusive worldwide licenses from The University of Texas MD Anderson Cancer Center (“MD Anderson”). Genprex believes that its ONCOPREX Delivery System allows for delivery of a number of cancer-fighting genes, alone or in combination with other cancer therapies, to combat multiple types of cancer and the Company is in early stages of discovery programs to identify other cancer candidates. In August 2022, Genprex entered into a three-year sponsored research agreement with MD Anderson to support further preclinical studies of TUSC2 and other tumor suppressor genes. Diabetes Gene Therapy In diabetes, the Company has exclusively licensed from the University of Pittsburgh of the Commonwealth System of Higher Education (“University of Pittsburgh”) multiple technologies relating to the development of a gene therapy product for each of Type 1 and Type 2 diabetes. The same general novel approach is used in each of Type 1 and Type 2 diabetes whereby an adeno-associated virus (“AAV”) vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. In humans, this can be done with a routine endoscopy procedure. The Company’s diabetes product candidates are currently being evaluated and optimized in preclinical studies at the University of Pittsburgh. GPX- 002 is being developed using the same construct for the treatment of both Type 1 diabetes and Type 2 diabetes. GPX- 002 for Type 1 diabetes is designed to work by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In a similar approach, GPX- 002 for Type 2 diabetes (formerly known as GPX- 003), where autoimmunity is not at play, is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin. Genprex finalized the components of the diabetes construct to take forward for nonclinical studies and in December 2023, the Company submitted a request to meet with the FDA to obtain their guidance on the nonclinical studies needed to file an Investigational New Drug (“IND”) application and initiate first-in-human studies. As a result of the FDA’s response, the Company will continue with its planned additional nonclinical studies before requesting regulatory guidance in 2024 for the IND-enabling studies. In October 2023, Genprex entered into a one-year extension to its August 2022 sponsored research agreement with the University of Pittsburgh for the use of GPX- 002 in a non-human primate (“NHP”) model in Type 2 diabetes. The extension includes a revised research plan to encompass the Company’s most recent technologies to which it acquired exclusive rights from the University of Pittsburgh in July 2023. These include a MafB promoter to drive expression of the Pdx1 and MafA transcription factors that can potentially be used for both Type 1 and Type 2 diabetes. See also “Note 7 – Commitments and Contingencies” to the Company’s financial statements included in this Annual Report on Form 10- K. In February 2023, the Company’s research collaborators at the University of Pittsburgh presented preclinical data in a NHP model of Type 1 diabetes highlighting the therapeutic potential of GPX- 002 at the 16th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD 2023) in Berlin, Germany. The statistically significant study results showed the treated animals had decreased insulin requirements, increased c-peptide levels, and improved glucose tolerance compared to baseline. In April 2023, the Company hosted a Key Opinion Leader virtual event entitled “Novel Gene Therapy to Treat Type 1 Diabetes,” which discussed preclinical data reported at ATTD 2023 supporting gene therapy to treat Type 1 diabetes. F- 9 Capital Requirements, Liquidity and Going Concern Considerations The Company’s financial statements are prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”) applicable to a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. However, as shown in the accompanying financial statements, the Company has sustained substantial losses from operations since inception and has no current source of revenue. In addition, the Company has used, rather than provided, cash in its operations. Genprex expects to continue to incur significant expenditures to further clinical trials for the commercial development of its patents. The Company recognizes that it must obtain additional capital resources to successfully commercialize its product candidates. To date, Genprex has received funding in the form of equity and debt, and the Company plans to seek additional funding in the future. However, no assurances can be given that it will be successful in raising additional capital. If the Company is not able to timely and successfully raise additional capital, the timing of its clinical trials, financial condition and results of operations may be materially and adversely affected. These financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts and classification of liabilities. Genprex believes that its current cash and cash equivalents will be sufficient to fund expenditure requirements for its necessary operations and expected clinical trial activities into the third quarter of 2024. Genprex has based these estimates, however, on assumptions that may prove to be wrong, and could spend available financial resources much faster than it currently expects. The Company will need to raise additional funds to continue funding its development and operations. The Company plans to secure such additional funding, although there are no guarantees or commitments for additional funding. As a result of its recurring losses from operations and the need for additional financing to fund its operating and capital requirements, there is uncertainty regarding the Company’s ability to maintain liquidity sufficient to operate its business effectively, which raises substantial doubt as to the Company’s ability to continue as a going concern. These financial statements do not include any adjustments that might be necessary if Genprex is unable to continue as a going concern. Note 2 – Summary of Significant Accounting Policies Genprex’s financial statements have been prepared in accordance with US GAAP. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. In the Company’s opinion the financial statements include all adjustments (consisting of normal recurring accruals) necessary to make the financial statements not misleading. The results of operations for any interim periods are not necessarily indicative of results to be expected for the full year. A summary of the Company’s significant accounting policies consistently applied in the preparation of the accompanying financial statements follows. Reverse Stock Split On February 2, 2024, Genprex completed a 1-for-40 reverse stock split (“Reverse Split”) of its issued and outstanding shares of common stock. The Reverse Split did not change the number of authorized shares of common stock or par value. All references in these financial statements to shares, share prices, exercise prices, and other per share information in all periods have been adjusted, on a retroactive basis, to reflect the Reverse Split (See Note 4 – Equity – Reverse Stock Split). Reclassification of Prior Year Presentation Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations. An adjustment has been made to the Statement of Cash Flows for the year ended fiscal year ended December 31, 2022 to reclassify research and development supplies from an investing activity to an operating activity. Use of Estimates The preparation of the Company’s financial statements in conformity with US GAAP requires the Company 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 financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Cash and Cash Equivalents Genprex considers all highly liquid short-term investments with an initial maturity of three months or less to be cash equivalents. Any amounts of cash in financial institutions which exceed Federal Deposit Insurance Corporation (“FDIC”) insured limits expose the Company to cash concentration risk. Genprex has cash in a money market account and had $6,490,117 and $20,679,538 in excess of FDIC insured limits of $250,000 at December 31, 2023 and 2022, respectively. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows. F- 10 Net Loss Per Share Basic net loss per share is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period, without consideration for potential dilutive shares of common stock, which includes common stock equivalents consisting of (i) 632,323 unexercised options granted by the Company’s board of directors and warrants to purchase shares of common stock, and (ii) 51,862 unvested restricted stock units to purchase shares of common stock granted by the Company’s board of directors as of December 31, 2023. Fair Value of Financial Instruments The carrying amounts reported in the balance sheet for cash, money-market savings account, accounts receivable, and accounts payables approximate fair value because of the immediate or short-term maturity of these financial instruments. Property and Equipment Furniture and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, which range from three to five years. Routine maintenance and repairs are charged to expense as incurred and major renovations or improvements are capitalized. Research and Development Materials Costs Research and development expenditures consist of costs incurred to conduct research, develop engineering materials for further study, and develop clinical strategies for current and future programs associated with the Company's preclinical and Phase 1/2 clinical trials. These expenditures are expensed in the period incurred and include payments to collaborative research partners, manufacturing partners and consultants, and clinical strategy partners, wages and associated employee benefits, facilities, and overhead costs. Materials acquired to be used in clinical research, that have an alternative future use, are capitalized when the materials are acquired, and included in research and development supplies. These supplies are recognized as expense as they are consumed through use for testing or clinical activities, or have spoiled. The costs of materials that were acquired for a particular research and development activity and have no alternative future use are expensed in the period acquired. Research and development supplies purchased and capitalized for future use were $2,347,488 and $2,864,937 at December 31, 2023 and 2022, respectively. F- 11 Intellectual Property Intellectual property consists of legal and related costs associated with patents, trademarks, and other proprietary technology and rights developed, acquired, or licensed by Genprex that it believes contribute to a probable economic benefit toward such patents and activities. These costs incurred in connection with obtaining intellectual property protection, such as patent applications and filing fees associated with and patent protection, are capitalized. Intellectual property is stated at cost, to be amortized on a straight-line basis over the estimated useful lives of the assets. Accounting for Stock-Based Compensation Genprex uses the fair value-based method of accounting for stock-based compensation for options granted to employees, independent consultants and contractors. The Company measures options granted at fair value determined as of the grant date and recognize the expense over the periods in which the options vest or are expected to vest and related services are rendered based on the terms and conditions of the award. Generally, where the award only has a service condition, the requisite service period is the same as the vesting period. Long-Lived Assets Genprex reviews long-lived assets and certain identifiable intangibles held and used for possible impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In evaluating the fair value and future benefits of its intangible assets, the Company performs an analysis of the anticipated undiscounted future net cash flow of the individual assets over the remaining amortization period. The Company recognizes an impairment loss if the carrying value of the asset exceeds the discounted expected future cash flows. During the years ended December 31, 2023 and 2022, there were no deemed impairments of the Company’s long-lived assets. Recent Accounting Developments Accounting pronouncements issued but not effective until after December 31, 2023 are not expected to have a significant effect on the Company’s financial condition, results of operations, or cash flows. F- 12 Note 3 – Intellectual Property As of December 31, 2023, Genprex owned or had exclusive license agreements on 21 granted patents and 23 pending patent applications worldwide for technologies developed in- house or by researchers at the National Cancer Institute, MD Anderson, the University of Texas Southwestern Medical Center, and the University of Pittsburgh. These patents comprise various therapeutic, diagnostic, technical and processing claims. These license rights will be amortized on a straight-line basis over the estimated period of useful lives of the underlying patents or the license agreements. University of Pittsburgh On February 11, 2020, Genprex entered into an exclusive license agreement with the University of Pittsburgh for patented gene therapy technologies relating to the potential treatment of Type 1 and Type 2 diabetes.

As of December 31, 2023, Genprex had outstanding warrants to purchase 346,440 shares of common stock at a weighted average exercise price of $57.79 that have been issued to various consultants, investors, and placement agents of the Company. These warrants vest immediately or over periods ranging up to 12 months, are exercisable for a period of up to five years, enable the holders to purchase shares of the Company’s common stock at exercise prices ranging from $26.00 to $288.80 per share and have per-share fair values ranging from $13.85 to $185.00, based on Black-Scholes-Merton pricing models. The following assumptions were used in calculation of fair market value of options via Black-Scholes- Merton pricing models for the year ended December 31, 2023. Assumptions for the year ended December 31, 2022 are similar to those listed for the year ended December 31, 2023. Expected term (in years): Risk-free rate: Volatility: Dividend yield: Twelve Months Ended December 31, 2023 2.5 - 3.0 5.33% - 5.52% 83.42% 0% F- 14 2018 Equity Incentive Plan Genprex’s board of directors and stockholders have approved and adopted the Company’s 2018 Equity Incentive Plan (“2018 Plan”), which became effective on the completion of the IPO on April 3, 2018. The 2018 Plan provides for the grant of incentive stock options that are intended to qualify under Section 422 of the Internal Revenue Code of 1986, as amended (“ISOs”), nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based stock awards and performance- based cash awards. ISOs may be granted only to employees of the Company. All other awards may be granted to employees, including officers, and to non-employee directors and consultants of the Company. The number of shares of common stock reserved for issuance under the 2018 Plan automatically increase on January 1 of each year (the “evergreen provision”), beginning January 1, 2019 by 5% of the total number of shares of the Company’s common stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by the Company’s board of directors or a committee appointed to administer the 2018 Plan. On January 1, 2023 and 2022, the number of shares of common stock reserved for issuance under the 2018 Plan was increased by an aggregate of 60,132 and 59,843 shares, respectively. As of December 31, 2023, a total of 11,686 shares of common stock remain available for issuance for future awards under the 2018 Plan.

The ESPP has not yet been utilized as a benefit available to the Company’s employees. The ESPP authorizes the issuance of 5,202 shares of the Company’s common stock pursuant to purchase rights that may be granted to its eligible employees. The number of shares of common stock reserved for issuance under the ESPP is automatically increased on January 1 of each calendar year, beginning on January 1, 2019, by 2% of the total number of shares of the Company’s common stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by the administrator of the ESPP. The administrator of the ESPP determined not to increase the number of shares reserved for issuance under the ESPP on January 1, 2023. F- 15 Stock Options As of December 31, 2023, Genprex had outstanding stock options to purchase 285,883 shares of common stock that have been granted to various executives, employees, directors, and independent contractors of the Company, including outstanding stock options to purchase 25,417 shares of common stock issued as inducement grants, outside of the 2018 Plan, associated with the hiring of new executives in 2021 and 2023. These options vest immediately or over periods ranging from 12 to 48 months, are exercisable for a period of up to ten years, and enable the holders to purchase shares of the Company’s common stock at exercise prices ranging from $18.00 to $140.00 per share. The per-share fair values of these options range from $12.62 to $98.84, based on Black-Scholes-Merton pricing models with the following assumptions: Expected term (in years): Risk-free rate: Volatility: Dividend yield: Twelve Months Ended December 31, 2023 6.0 4.60% – 5.37% 83.14% - 83.42% 0% Twelve Months Ended December 31, 2022 10 0.07% – 4.77% 75.98% - 88.38% 0% During the year ended December 31, 2023, Genprex (i) granted stock options to purchase an aggregate of 8,251 shares of the Company’s common stock with exercise prices ranging from $18.00 to $60.40 per share to employees, (ii) cancelled options to purchase 6,245 shares of common stock at an exercise prices ranging from $50.80 to $142.00 per share in connection with the termination of certain employees, and (iii) issued 500 shares of the Company’s common stock upon the exercise of options held by a former board member with an exercise price of $11.92 per share.

Stock option activity for the years ended December 31, 2023 and 2022, respectively, is as follows: Number of Options 2023 Weighted Average Exercise Price Number of Options 2022 Weighted Average Exercise Price Outstanding at January 1, Options granted Options exercised Options expired or cancelled Outstanding at December 31, Exercisable at December 31, 284,377 8,251 500 6,245 285,883 237,859 $ 123.19 30.14 11.92 104.42 $ 121.11 $ 124.73 F- 16 214,370 74,600 2,925 1,668 284,377 167,957 $ 134.14 86.45 0.60 101.88 $ 123.19 $ 129.19 Restricted Stock Units A summary of the RSU activity under the 2018 Plan during the year ended December 31, 2023, is presented below. These amounts include RSUs granted to executives, other employees, and board members. There was no RSU activity for the year ended December 31, 2022. Outstanding at January 1, Restricted stock units granted Restricted stock units forfeited or cancelled Outstanding at December 31, Share-Based Compensation Number of Units 2023 Weighted Average Grant Date Fair Value $ — 60.08 66.00 $ 59.48 — 57,119 5,257 51,862 In the year ended December 31, 2023, Genprex’s total share-based compensation was approximately $5.4 million, consisting of $4.4 million and $1.0 million associated with G&A expense and R&D expense, respectively, which represents the vesting of options and warrants issued to service providers, executives, employees, and board members of the Company. As of December 31, 2023, the Company’s total compensation cost related to non-vested time-based stock option awards, RSUs, and warrants granted to executives, employees, board members, and service providers and not yet recognized was approximately $4.7 million, consisting of $3.8 million and $0.9 million associated with G&A expense and R&D expense, respectively. Genprex expects to record this stock-based compensation expense over the next three years using a graded vesting method. As of December 31, 2023, the weighted average term over which these expenses are expected to be recognized is 1.12 years. As of December 31, 2023, there are no performance-based stock option awards outstanding and one performance-based warrant outstanding issued to a service provider of the Company. Genprex’s total compensation cost related to the non-vested performance-based warrant not yet recognized was approximately $300,000. The entirety of this warrant may be recognized and recorded upon the achievement of certain milestones. In the year ended December 31, 2022, the Company’s total share-based compensation was approximately $4.7 million with approximately $4.6 million representing the vesting of options issued to service providers, employees, and board members of the Company. Note 5 - 401(k) Savings Transactions In 2022, Genprex established a defined-contribution savings plan under Section 401(k) of the Internal Revenue Code (“401(k) Plan”) and established an employer matching program for participants in the 401(k) Plan. The 401(k) Plan covers all employees who meet defined minimum age and service requirements, and allows participants to defer a portion of their annual compensation on a pre-tax basis. Genprex incurred $141,564 and $74,281 of expense for matching contributions to the 401(k) Plan for the years ended December 31, 2023 and 2022, respectively. Note 6 - Related Party Transactions Introgen Research Institute Introgen Research Institute (“IRI”) is a Texas-based technology company formed by Rodney Varner, Genprex’s President, Chief Executive Officer and Chairman of the Board and IRI’s sole officer. IRI is owned by trusts of which Mr. Varner’s descendants are the sole beneficiaries. In April 2009, prior to Mr. Varner becoming an officer and director of the Company in August 2012, Genprex entered into an Assignment and Collaboration Agreement with IRI, providing the Company with the exclusive right to commercialize a portfolio of intellectual property. This agreement was amended in 2011 to include additional sublicensing of additional intellectual property made available to IRI from MD Anderson (See Note 7 – Commitments and Contingences – Commitments – MD Anderson Cancer Center). F- 17 Note 7 - Commitments and Contingencies Commitments MD Anderson In July 2018, Genprex entered into a two-year sponsored research agreement with MD Anderson to sponsor preclinical studies focused on the combination of REQORSA with an immunotherapy with a projected total cost of approximately $2 million. This agreement was extended beyond the original expiration date. This agreement expired in May 2022. In August 2022, Genprex entered into a three-year sponsored research agreement with MD Anderson to sponsor preclinical studies focused on REQORSA and other potential product candidates in oncology to resensitize NSCLC and SCLC to targeted therapies and immunotherapies with a projected total cost of approximately $2.9 million. As of December 31, 2023, Genprex has paid approximately $1.2 million toward this commitment. In 2011, Genprex agreed to assume certain contractual and other obligations of IRI in consideration for the sublicense rights, expertise, and assistance associated with certain technologies and intellectual property originally licensed to another party under the 1994 License Agreement with MD Anderson (“Original MD Anderson License Agreement”). These technologies and intellectual property were later sublicensed to IRI (the “IRI Sublicense”). Genprex also agreed to pay royalties of 1% on sales of certain licensed products for a period of 21 years following the termination of the later of the Original MD Anderson License Agreement and the IRI Sublicense. The Company assumed patent prosecution costs and an annual minimum royalty of $20,000 payable to the National Institutes of Health. On March 3, 2021, Genprex entered into an amendment (the “MD License Amendment”) to the Patent and Technology License Agreement dated May 4, 2020, with MD Anderson. The MD License Amendment grants the Company with a worldwide, exclusive, sublicensable license to an additional portfolio of six patents and one patent application and related technology for methods for treating cancer by administration of a TUSC2 therapy in conjunction with EGFR inhibitors or other anti-cancer therapies in patients predicted to be responsive to TUSC2 therapy. Pursuant to the MD License Amendment, Genprex agreed to (i) pay annual maintenance fees ranging from the mid five figures to the low six figures, (ii) total milestone payments of $6,150,000, (iii) a one-time fee in the mid five figures and (iv) certain patent related expenses. As of December 31, 2023, Genprex has paid approximately $320,000 toward this commitment. National Institutes of Health Genprex has a royalty obligation to the National Institutes of Health (“NIH”) to be paid upon the Company’s receipt of FDA approval using NIH technology. The $240,000 contingent obligation which increases annually by $20,000 and is $360,000 and $340,000 for the years ended December 31, 2023 and 2022, respectively, will be recognized when the Company obtains regulatory approval (the event that triggers the payment obligation).

Contingencies From time to time, the Company may become subject to threatened and/or asserted claims arising in the ordinary course of its business.

F- 19 Note 8 – Income Taxes Components of income tax benefit for the year ended December 31, 2023 and 2022, respectively, are as follows: Current Tax Expense (Benefit): Federal State Total Deferred Tax Expense (Benefit): Federal State Total Total Provision for Income Taxes December 31, 2023 December 31, 2022 — — — — — — — — — — — — — — Temporary differences between financial statement carrying amount and tax basis of assets and liabilities that give rise to significant portions of the deferred tax assets and liabilities at December 31, 2023 and 2022, respectively, are as follows: December 31, 2023 December 31, 2022 Deferred tax assets: Allowance for Doubtful Accounts Interest Expense Intangible Assets - R&D Expenses Accrued Expenses Tax Credits Stock Compensation Expense Net Operating Losses Total Deferred Income Tax Assets Deferred Income Tax Liabilities: Fixed Assets Intangible Assets Prepaid Expenses Lease - Right of Use Unrealized Gain/Loss Total Deferred Income Tax Liabilities Less Valuation Allowance Net Deferred Income Tax Asset — — 4,710,079 684,699 1,434,851 306,906 16,915,002 24,051,538 (1,650) — (629,136) — — (630,786) (23,420,752) — — — 1,986,102 561,496 728,701 94,237 14,464,170 17,834,706 (4,354) — (710,643) — — (714,997) (17,119,710) — At December 31, 2023 and 2022, the Company had federal net operating losses of $80.5 million and $68.9 million, respectively. Net deferred tax assets are mainly comprised of temporary differences between financial statement carrying amount and tax basis of assets and liabilities. In assessing the ability to realize the deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent on the generation of future taxable income during the period in which these temporary differences become deductible. Management considers the projected future taxable income and prudent and feasible tax planning strategies in making this assessment. As of December 31, 2023 and 2022, valuation allowances of $23.4 million and $17.1 million have been recorded, respectively. The Company has federal research and development (“R&D”) credit carryforwards of $1.4 million which will begin to expire in 2037. Effective January 1, 2009 the Company adopted ASC 740-10, the provision formerly FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, (“FIN48”) and began evaluating tax positions utilizing a two-step process. The first step is to determine whether it is more-likely-than-not that a tax position will be sustained upon examination based on the technical merits of the position. The second step is to measure the benefit to be recorded from tax positions that meet the more-likely-than-not recognition threshold by determining the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement and recognizing that amount in the financial statements. F- 20 Note 9 – Subsequent Events Reserves of 2018 Equity Incentive Plan and 2018 Employee Stock Purchase Plan On January 1, 2024, the total shares of common stock reserved under the 2018 Plan increased by 74,294 shares.

Exhibit 3.1 Rodney Varner, hereby certifies that: ONE: He is the duly elected and acting Chief Executive Officer of Genprex, Inc., a Delaware corporation. TWO: The date of filing of said corporation’s original certificate of incorporation with the Delaware Secretary of State was April 1, 2009. THREE: The Third Amended and Restated Certificate of Incorporation of the corporation, as amended, is hereby amended and restated to read in its entirety as follows: The name of this corporation is Genprex, Inc. (the “Company”). I. II. The address of the registered office of the Company in the State of Delaware is 1209 Orange Street, in the City of Wilmington, Delaware, 19801, County of New Castle. The name of its registered agent at such address is The Corporation Trust Company. The purpose of the Company is to engage in any lawful act or activity for which a corporation may be organized under the Delaware General Corporation Law (“DGCL”). III. IV. A. The Company is authorized to issue two classes of stock to be designated, respectively, “Common Stock” and “Preferred Stock.” The total number of shares which the Company is authorized to issue is 210,000,000 shares. 200,000,000 shares shall be Common Stock, each having a par value of $0.001. 10,000,000 shares shall be Preferred Stock, each having a par value of $0.001. B. The Preferred Stock may be issued from time to time in one or more series. The Board of Directors of the Company (the “Board of Directors”) is hereby expressly authorized to provide for the issue of any or all of the unissued and undesignated shares of the Preferred Stock in one or more series, and to fix the number of shares and to determine or alter for each such series, such voting powers, full or limited, or no voting powers, and such Designation, preferences, and relative, participating, optional, or other rights and such qualifications, limitations, or restrictions thereof, as shall be stated and expressed in the resolution or resolutions adopted by the Board of Directors providing for the issuance of such shares and as may be permitted by the DGCL. The Board of Directors is also expressly authorized to increase or decrease the number of shares of any series subsequent to the issuance of shares of that series, but not below the number of shares of such series then outstanding. In case the number of shares of any series shall be decreased in accordance with the foregoing sentence, the shares constituting such decrease shall resume the status that they had prior to the adoption of the resolution originally fixing the number of shares of such series. The number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power of the stock of the Company entitled to vote thereon, without a separate vote of the holders of the Preferred Stock, or of any series thereof, unless a vote of any such holders is required pursuant to the terms of any certificate of Designation filed with respect to any series of Preferred Stock. C. Each outstanding share of Common Stock shall entitle the holder thereof to one vote on each matter properly submitted to the stockholders of the Company for their vote; provided, however, that, except as otherwise required by law, holders of Common Stock shall not be entitled to vote on any amendment to this Amended and Restated Certificate of Incorporation (this “Certificate of Incorporation”) (including any certificate of Designation filed with respect to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series of Preferred Stock are entitled, either separately or together as a class with the holders of one or more other such series of Preferred Stock, to vote thereon by law or pursuant to this Certificate of Incorporation (including any certificate of Designation filed with respect to any series of Preferred Stock). V. For the management of the business and for the conduct of the affairs of the Company, and in further definition, limitation and regulation of the powers of the Company, of its directors and of its stockholders or any class thereof, as the case may be, it is further provided that: A. The management of the business and the conduct of the affairs of the Company shall be vested in its Board of Directors. The number of directors that shall constitute the Board of Directors shall be fixed exclusively by resolutions adopted by a majority of the authorized number of directors constituting the Board of Directors. B. Subject to the rights of the holders of any series of Preferred Stock to elect additional directors under specified circumstances, the directors shall be divided into three classes designated as Class I, Class II and Class III, respectively. The Board of Directors is authorized to assign members of the Board of Directors already in office to such classes at the time the classification becomes effective. At the first annual meeting of stockholders following the initial classification of the Board of Directors, the term of office of the Class I directors shall expire and Class I directors shall be elected for a full term of three years. At the second annual meeting of stockholders following such initial classification, the term of office of the Class II directors shall expire and Class II directors shall be elected for a full term of three years. At the third annual meeting of stockholders following such initial classification, the term of office of the Class III directors shall expire and Class III directors shall be elected for a full term of three years. At each succeeding annual meeting of stockholders, directors shall be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual meeting. Notwithstanding the foregoing provisions of this section, each director shall serve until his or her successor is duly elected and qualified or until his or her earlier death, resignation or removal. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director. C. Subject to the rights of any series of Preferred Stock that may be designated from time to time to elect additional directors under specified circumstances, neither the Board of Directors nor any individual director may be removed without cause. Subject to any limitations imposed by applicable law, any individual director or directors may be removed with cause by the affirmative vote of the holders of at least 66 2/3% of the voting power of all then-outstanding shares of capital stock of the Company entitled to vote generally at an election of directors, voting together as a single class. D. Subject to any limitations imposed by applicable law and subject to the rights of the holders of any series of Preferred Stock that may be designated from time to time, any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or other causes and any newly created directorships resulting from any increase in the number of directors, shall, unless the Board of Directors determines by resolution that any such vacancies or newly created directorships shall be filled by the stockholders and except as otherwise provided by applicable law, be filled only by the affirmative vote of a majority of the directors then in office, even though less than a quorum of the Board of Directors, and not by the stockholders. Any director elected in accordance with the preceding sentence shall hold office for the remainder of the full term of the director for which the vacancy was created or occurred and until such director’s successor shall have been elected and qualified. E. The Board of Directors is expressly empowered to adopt, amend or repeal the Amended and Restated Bylaws of the Company (the “Bylaws”). Any adoption, amendment or repeal of the Bylaws by the Board of Directors shall require the approval of a majority of the authorized number of directors. The stockholders shall also have power to adopt, amend or repeal the Bylaws; provided, however, that, in addition to any vote of the holders of any class or series of stock of the Company required by law or by this Certificate of Incorporation, such action by stockholders shall require the affirmative vote of the holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of the capital stock of the Company entitled to vote generally in the election of directors, voting together as a single class. F. The directors of the Company need not be elected by written ballot unless the Bylaws so provide. G. No action shall be taken by the stockholders of the Company except at an annual or special meeting of stockholders called in accordance with the Bylaws. No action shall be taken by the stockholders of the Company by written consent or electronic transmission. H. Advance notice of stockholder nominations for the election of directors and of business to be brought by stockholders before any meeting of the stockholders of the Company shall be given in the manner provided in the Bylaws. VI. A. The liability of a director of the Company for monetary damages shall be eliminated to the fullest extent under applicable law. B. To the fullest extent permitted by applicable law, the Company is authorized to provide indemnification of (and advancement of expenses to) directors, officers and agents of the Company (and any other persons to which applicable law permits the Company to provide indemnification) through Bylaw provisions, agreements with such agents or other persons, vote of stockholders or disinterested directors or otherwise in excess of the indemnification and advancement otherwise permitted by such applicable law. If applicable law is amended after approval by the stockholders of this Article VI to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director to the Company shall be eliminated or limited to the fullest extent permitted by applicable law as so amended. C. Any repeal or modification of this Article VI shall only be prospective and shall not affect the rights or protections or increase the liability of any director under this Article VI in effect at the time of the alleged occurrence of any act or omission to act giving rise to liability or indemnification. VII. Unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (1) any derivative action or proceeding brought on behalf of the Company; (2) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company to the Company or the Company’s stockholders; (3) any action asserting a claim against the Company or any director or officer or other employee of the Company arising pursuant to any provision of the DGCL, the Company’s Certificate of Incorporation or Bylaws; or (4) any action asserting a claim against the Company or any director or officer or other employee of the Company governed by the internal affairs doctrine. VIII. A. The Company reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute, except as provided in Section B of this Article VIII, and all rights conferred upon the stockholders herein are granted subject to this reservation. B. Notwithstanding any other provisions of this Certificate of Incorporation or any provision of law which might otherwise permit a lesser vote or no vote, but in addition to any affirmative vote of the holders of any particular class or series of the Company required by law or by this Certificate of Incorporation or any certificate of Designation filed with respect to a series of Preferred Stock that may be designated from time to time, subject to the rights of the holders of any series of Preferred Stock, the affirmative vote of the holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of capital stock of the Company entitled to vote generally in the election of directors, voting together as a single class, shall be required to alter, amend or repeal Articles V, VI or VIII of this Certificate of Incorporation. FOUR: This Certificate of Incorporation has been duly adopted and approved by the Board of Directors and by written consent of the stockholders in accordance with Sections 228, 242 and 245 of the DGCL and written notice of such action has been given as provided in section 228 of the DGCL.

GENPREX, INC. /s/ RODNEY VARNER Rodney Varner Chief Executive Officer CERTIFICATE OF AMENDMENT OF THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF GENPREX, INC. Genprex, Inc. (the “Company”), a corporation duly organized and validly existing under and by virtue of the General Corporation Law of the State of Delaware (the “DGCL”); DOES HEREBY CERTIFY AS FOLLOWS: FIRST: That the Amended and Restated Certificate of Incorporation of the Company (as heretofore amended, the “Amended and Restated Certificate of Incorporation”) is hereby amended as follows: Article IV of the Amended and Restated Certificate of Incorporation be and hereby is amended by adding the following after the first paragraph of Section A of Article IV: “Upon the effectiveness (“Effective Time”) of this amendment to the Certificate of Incorporation, a one-for-forty reverse stock split (the “Reverse Split”) of the Company’s Common Stock shall become effective, pursuant to which each forty (40) shares of Common Stock outstanding and held of record by each stockholder of the Company or held in treasury by the Company immediately prior to the Effective Time (“Old Common Stock”) shall automatically, and without any action by the holder thereof, be reclassified and combined into one (1) validly issued, fully paid and non-assessable share of Common Stock (“New Common Stock”), subject to the treatment of fractional interests as described below and with no corresponding reduction in the number of authorized shares of Common Stock. The Reverse Split shall also apply to any outstanding securities or rights convertible into, or exchangeable or exercisable for, Old Common Stock and all references to such Old Common Stock in agreements, arrangements, documents and plans relating thereto or any option or right to purchase or acquire shares of Old Common Stock shall be deemed to be references to the New Common Stock or options or rights to purchase or acquire shares of New Common stock, as the case may be, after giving effect to the Reverse Split. No fractional shares of Common Stock will be issued in connection with the Reverse Split. If, upon aggregating all of the Common Stock held by a holder of Common Stock immediately following the Reverse Split a holder of Common Stock would otherwise be entitled to a fractional share of Common Stock, the Company shall issue to such holder such fractions of a share of Common Stock as are necessary to round the number of shares of Common Stock held by such holder up to the nearest whole share. Each holder of record of a certificate or certificates for one or more shares of the Old Common Stock shall be entitled to receive as soon as practicable, upon surrender of such certificate, a certificate or certificates representing the largest whole number of shares of New Common Stock to which such holder shall be entitled pursuant to the provisions of the immediately preceding paragraphs. Each stock certificate that, immediately prior to the Effective Time, represented shares of Old Common Stock that were issued and outstanding immediately prior to the Effective Time shall, from and after the Effective Time, automatically and without the necessity of presenting the same for exchange, represent that number of whole shares of New Common Stock after the Effective Time into which the shares formerly represented by such certificate have been reclassified, subject to adjustment for fractional shares as described above.” SECOND: That the amendment set forth in this Certificate of Amendment was duly adopted by the Board of Directors of the Company and the stockholders of the Company in accordance with Section 242 of the DGCL. THIRD: That said amendment will have an Effective Time of 12:01 a.m., Eastern Time, on February 2, 2024.

Anti-takeover effects of our Charter Documents and Delaware law Set forth below is a summary of the provisions of the Company’s Certificate of Incorporation and Bylaws and the DGCL that could have the effect of delaying or preventing a change in control of the Company. The following description is only a summary, and it is qualified by reference to the Certificate of Incorporation, Bylaws and relevant provisions of the DGCL. Delaware Anti-Takeover Law The Company is subject to Section 203 of the DGCL (“Section 203”) which generally prohibits a publicly held Delaware corporation from engaging in a “business combination” transaction with an “interested stockholder” for a period of three years following the time that such stockholder became an interested stockholder, unless: ● prior to the date of the transaction the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; ● upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (1) by persons who are directors and also officers and (2) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or ● at or subsequent to the date of the transaction, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66-2/3% of the outstanding voting stock which is not owned by the interested stockholder. Section 203 defines a “business combination” to include: ● any merger or consolidation involving the corporation and the interested stockholder; ● any sale, lease, exchange, mortgage, transfer, pledge or other disposition (in one transaction or a series of transactions) involving the interested stockholder of assets of the corporation or of any direct or indirect majority-owned subsidiary of the corporation which assets have an aggregate market value equal to 10% or more of either the aggregate market value of all the assets of the corporation determined on a consolidated basis or the aggregate market value of all the outstanding stock of the corporation; ● subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder; ● subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation beneficially owned by the interested stockholder; or ● the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation. In general, Section 203 defines an “interested stockholder” a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, owned 15% or more of a corporation’s outstanding voting securities. Certificate of Incorporation and Bylaws Board of Directors Vacancies The Company’s Charter Documents provide that, except as otherwise required by law, and subject to the rights of the holders of any series of Preferred Stock, all vacancies, and any newly created directorships, unless the Board of Directors determines that any such vacancies or newly created directorships shall be filled by the stockholders, shall, be filled only by the affirmative vote of a majority of directors then in office, even if less than a quorum. Further, the Company’s directors may only be removed with cause and by the affirmative vote of the holders of at least 66-2/3% of the voting power of all of the Company’s then outstanding capital stock. In addition, pursuant to the Company’s Certificate of Incorporation, the number of directors constituting the Company’s board of directors may be changed only by resolution of the Company’s board of directors. Limits on Ability of Stockholders to Act by Written Consent or Call a Special Meeting The Company’s Charter Documents require that any action to be taken by our stockholders must be effected at a duly called annual or special meeting of stockholders and not be taken by written consent. In addition, pursuant to the Company’s Bylaws, special meetings of the Company’s stockholders may be called only by the chairman of the board, the Company’s Chief Executive Officer or by the board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors. Stockholder Proposals The Company’s Bylaws provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide notice in writing in a timely manner and also specify requirements as to the form and content of a stockholder’s notice. These advance notice procedures may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed and may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempt to obtain control of our company. Staggered Board The Company’s Charter Documents provide that the Company’s board of directors shall be divided into three classes and that directors shall be elected for a term of three years. Our classified board of directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us because it generally makes it more difficult for stockholders to replace a majority of the directors. Issuance of Undesignated Preferred Stock As discussed above, our board of directors has the ability to designate and issue preferred stock with voting or other rights or preferences that could deter hostile takeovers or delay changes in our control or management. No Cumulative Voting The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless our certificate of incorporation provides otherwise. Our Charter Documents do not expressly provide for cumulative voting. Without cumulative voting, a minority stockholder may not be able to gain as many seats on our board of directors as the stockholder would be able to gain if cumulative voting were permitted. The absence of cumulative voting makes it more difficult for a minority stockholder to gain a seat on our board of directors to influence our board of directors’ decision regarding a takeover. Exclusive Forum The Company’s Charter Documents provide that unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for: (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim for breach of any fiduciary duty owed by any director, officer, or other employee of the Company to the Company or the Company’s stockholders, (iii) any action asserting a claim against the Company or any director or officer or other employee of the Company arising pursuant to any provision of the DGCL or the Company’s Certificate of Incorporation or Bylaws or (iv) any action asserting a claim against the Company or any of the Company’s directors, officers or other employees governed by the internal affairs doctrine. This exclusive forum provision would not apply to suits brought to enforce any liability or duty created by the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. Transfer Agent and Registrar The Company’s transfer agent and registrar is VStock Transfer, LLC whose address is 18 Lafayette Place, Woodmere, New York 11598. Listing The Company’s Common Stock is listed on The Nasdaq Capital Market under the symbol “GNPX.” GENPREX, INC. 2018 EQUITY INCENTIVE PLAN Purposes of the Plan. 1. Shares Subject to the Plan. 2.

The purposes of this Plan are to attract and retain personnel for positions with the Company, to provide additional incentive to Employees, Directors, and Consultants (collectively, “Service Providers”), and to promote the success of the Company’s business. The Plan permits the grant of Incentive Stock Options to Employees and the grant of Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Performance Shares, Performance Stock Units, and Performance Awards to any Service Provider. 2. Shares Subject to the Plan. (a) Allocation of Shares to Plan. The maximum aggregate number of Shares that may be issued under the Plan is: (i) 4,160,000 Shares, plus (ii) a number of Shares equal to the number of shares of common stock of the Company subject to outstanding awards granted under the Genprex, Inc. 2009 Stock Plan that, after the Registration Date, expire or otherwise terminate without having been exercised in full and a number of Shares equal to the number of Shares of common stock of the Company issued under awards granted under the Genprex, Inc. 2009 Stock Plan that, after the Registration Date, are forfeited to the Company, tendered to or withheld by the Company for payment of an exercise price or for tax withholding, or repurchased by the Company due to failure to vest, with the maximum number of Shares that may be added to the Plan under this Section 2(a)(i) being equal to 2,628,749 Shares, plus (iii) any additional Shares that become available for issuance under the Plan under Sections 2(b) and 2(c). The Shares may be authorized but unissued Common Stock or Common Stock issued and then reacquired by the Company. (b) Automatic Share Reserve Increase. The number of Shares available for issuance under the Plan will be increased on the first day of each Fiscal Year beginning with the 2019 Fiscal Year, in an amount equal to the lesser of: (i) 5% of the total number of shares of all classes of the Company’s common stock outstanding on the last day of the immediately preceding Fiscal Year, and (ii) a lower number of Shares determined by the Administrator. (c) Lapsed Awards. is surrendered under an Exchange Program, the unissued Shares subject to the Option or Stock Appreciation Right will become available for future issuance under the Plan. (i) Options and Stock Appreciation Rights. If an Option or Stock Appreciation Right expires or becomes unexercisable without having been exercised in full or - 2 - (ii) Stock Appreciation Rights. Only Shares actually issued pursuant to a Stock Appreciation Right (i.e., the net Shares issued) will cease to be available under the Plan; all remaining Shares originally subject to the Stock Appreciation Right will remain available for future issuance under the Plan. (iii) Full-Value Awards. Shares issued pursuant to Awards of Restricted Stock, Restricted Stock Units, Performance Shares, Performance Stock Units or stock- settled Performance Awards that are reacquired by the Company due to failure to vest or are forfeited to the Company will become available for future issuance under the Plan. (iv) Withheld Shares. Shares used to pay the Exercise Price of an Award or to satisfy tax withholding obligations related to an Award will become available for future issuance under the Plan. (v) Cash-Settled Awards. If any portion of an Award under the Plan is paid to a Participant in cash rather than Shares, that cash payment will not reduce the number of Shares available for issuance under the Plan. (d) Incentive Stock Options. The maximum number of Shares that may be issued upon the exercise of Incentive Stock Options will equal 200% of the aggregate Share number stated in Section 2(a) plus, to the extent allowable under Code Section 422, any Shares that become available for issuance under the Plan under Sections 2(b) and 2(c). (e) Adjustment. The numbers provided in Sections 2(a), 2(b), and 2(d) will be adjusted as a result of changes in capitalization referred to in Section 13. (f) Substitute Awards. If the Committee grants Awards in substitution for equity compensation awards outstanding under a plan maintained by an entity acquired by or consolidated with the Company, the grant of those substitute Awards will not decrease the number of Shares available for issuance under the Plan. 3. Administration of the Plan. (a) Procedure. (i) General. The Plan will be administered by the Board or a Committee (the “Administrator”). Different Administrators may administer the Plan with respect to different groups of Service Providers. The Board may retain the authority to concurrently administer the Plan with a Committee and may revoke the delegation of some or all authority previously delegated. (ii) Further Delegation. To the extent permitted by Applicable Laws, the Board or a Committee may delegate to 1 or more Officers the authority to grant Awards to Employees of the Company or any of its Subsidiaries who are not Officers, provided that the delegation must specify any limitations on the authority required by Applicable Laws, including the total number of Shares that may be subject to the Awards granted by such Officer(s). Such delegation may be revoked at any time by the Board or Committee. Any such Awards will be granted on the form of Award Agreement most recently approved for use by the Board or a Committee made up solely of Directors, unless the resolutions delegating the authority permit the Officer(s) to use a different form of Award Agreement approved by the Board or a Committee made up solely of Directors. - 3 - (iii) Section 162(m). When necessary or desirable for an Award to qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee shall include at least two persons who are “outside directors” (as defined under Section 162(m) of the Code) and at least two (or a majority if more than two then serve on the Committee) such “outside directors” shall approve the grant of such Award and determine (as applicable) the Performance Period and any Performance Factors upon which vesting or settlement of any portion of such Award is to be subject no later than the earlier of (a) the date 90 days after the commencement of the applicable Performance Period, and (b) the date on which 25% of the Performance Period has elapsed, and in any event at a time when the achievement of the applicable Performance Factors remains substantially uncertain. When required by Section 162(m) of the Code, prior to settlement of any such Award at least two (or a majority if more than two then serve on the Committee) such “outside directors” then serving on the Committee shall determine and certify in writing the extent to which such Performance Factors have been timely achieved and the extent to which the Shares subject to such Award have thereby been earned. Awards granted to Participants who are subject to Section 16 of the Exchange Act must be approved by two or more “non-employee directors” (as defined in the regulations promulgated under Section 16 of the Exchange Act). With respect to Participants whose compensation is subject to Section 162(m) of the Code, and provided that such adjustments are consistent with the regulations promulgated under Section 162(m) of the Code, the Committee may adjust the performance goals to account for changes in law and accounting and to make such adjustments as the Committee deems necessary or appropriate to reflect the impact of extraordinary or unusual items, events or circumstances to avoid windfalls or hardships, including without limitation (i) restructurings, discontinued operations, extraordinary items, and other unusual or non-recurring charges, (ii) an event either not directly related to the operations of the Company or not within the reasonable control of the Company’s management, or (iii) a change in accounting standards required by generally accepted accounting principles. No Participant will be eligible to receive more than 1,175,000 (25% of Share Reserve Shares) in any calendar year under this Plan pursuant to the grant of Awards except that new Employees of the Company or a member of the Company Group (including new Employees who are also officers and directors of the Company or a member of the Company Group) are eligible to receive up to a maximum of 2,350,000 (50% of Share Reserve Shares) in the calendar year in which they commence their employment, and no Participant shall be granted a cash settled award with a value greater than $2,000,000. (b) Powers of the Administrator. Subject to the terms of the Plan, any limitations on delegations specified by the Board, and any requirements imposed by Applicable Laws, the Administrator will have the authority, in its sole discretion, to make any determinations and perform any actions deemed necessary or advisable to administer the Plan including: (i) to determine the Fair Market Value; (ii) to approve forms of Award Agreements for use under the Plan (provided that all forms of Award Agreement must be approved by the Board or the Committee of Directors acting as the Administrator); - 4 - (iii) to select the Service Providers to whom Awards may be granted and grant Awards to such Service Providers; (iv) to determine the number of Shares to be covered by each Award granted; (v) to determine the terms and conditions, consistent with the Plan, of any Award granted. Such terms and conditions may include, but are not limited to, the Exercise Price, the time(s) when Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Award or the Shares relating to an Award; (vi) to institute and determine the terms and conditions of an Exchange Program; (vii) to interpret the Plan and make any decisions necessary to administer the Plan; United States or to qualify Awards for favorable tax treatment under laws of jurisdictions other than the United States; (viii) to establish, amend and rescind rules relating to the Plan, including rules relating to sub-plans established to satisfy laws of jurisdictions other than the (ix) to interpret, modify or amend each Award (subject to Section 18), including extending the Expiration Date and the post-termination exercisability period of such modified or amended Awards; (x) to allow Participants to satisfy tax withholding obligations in any manner permitted by Section 15; (xi) to delegate ministerial duties to any of the Company’s employees; (xii) to authorize any person to take any steps and execute, on behalf of the Company, any documents required for an Award previously granted by the Administrator to be effective; and (xiii) to allow Participants to defer the receipt of the payment of cash or the delivery of Shares otherwise due to any such Participants under an Award. (c) Termination of Status. (i) Unless a Participant is on a leave of absence approved by the Company as set forth in Section 11, the Participant’s status as a Service Provider will end at midnight at the end of the last day the Participant actively provides services for a member of the Company Group (the “Termination of Status Date”). The Administrator has the sole discretion to determine the date on which a Participant stops actively providing services and whether a Participant may still be considered to be providing services while on a leave of absence and the Administrator may delegate this decision, other than with respect to Officers, to the Company’s senior human resources officer. - 5 - (ii) This termination of status as a Service Provider will occur regardless of the reason for such termination even if the termination is later found to be invalid, in breach of employment laws in the jurisdiction where Participant is providing services, or in violation of the terms of Participant’s employment or service agreement, if any such agreement exists. (iii) Unless otherwise expressly provided in an Award Agreement or otherwise determined by the Administrator, a Participant’s right to vest in any Award under the Plan will cease as of the Termination of Status Date and will not be extended by any notice period, whether arising under contract, statute or common law, including any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Participant is providing services. (d) Grant Date. The grant date of an Award (“Grant Date”) will be the date that the Administrator makes the determination granting such Award or may be a later date if such later date is designated by the Administrator on the date of the determination or under an automatic grant policy. Notice of the determination will be provided to each Participant within a reasonable time after the Grant Date. (e) Waiver. The Administrator may waive any terms, conditions or restrictions. (f) Fractional Shares. Except as otherwise provided by the Administrator, any fractional Shares that result from the adjustment of Awards will be canceled. Any fractional Shares that result from vesting percentages will be accumulated and vested on the date that an accumulated full Share is vested. (g) Electronic Delivery. The Company may deliver by e-mail or other electronic means (including posting on a website maintained by the Company or by a third party under contract with the Company or another member of the Company Group) all documents relating to the Plan or any Award and all other documents that the Company is required to deliver to its security holders (including prospectuses, annual reports and proxy statements). (h) Choice of Law; Choice of Forum. The Plan, all Awards and all determinations made and actions taken under the Plan, to the extent not otherwise governed by the laws of the United States, will be governed by the laws of the State of Delaware without giving effect to principles of conflicts of law. For purposes of litigating any dispute that arises under this Plan, a Participant’s acceptance of an Award is his or her consent to the jurisdiction of the State of Delaware, and agreement that any such litigation will be conducted in Delaware Court of Chancery, or the federal courts for the United States for the District of Delaware, and no other courts, regardless of where a Participant’s services are performed. (i) Effect of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations will be final and binding on all Participants and any other holders of Awards. 4. Stock Options. (a) Stock Option Award Agreement. Each Option will be evidenced by an Award Agreement that will specify the number of Shares subject to the Option, its per share exercise price (“Exercise Price”), its Expiration Date, and such other terms and conditions as the Administrator determines. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. An Option not designated as an Incentive Stock Option is a Nonstatutory Stock Option. - 6 - (b) Exercise Price. The Exercise Price for the Shares to be issued upon exercise of an Option will be determined by the Administrator. (c) Form of Consideration. The Administrator will determine the acceptable forms of consideration for exercising an Option and those forms of consideration will be described in the Award Agreement. The consideration may consist of any combination of the following, to the extent permitted by Applicable Laws: (i) cash; (ii) check or wire transfer; (iii) promissory note; (iv) other Shares that have a fair market value on the date of surrender equal to the aggregate Exercise Price of the Shares as to which such Option will be exercised. To the extent not prohibited by the Administrator, this shall include the ability to tender Shares to exercise the Option and then use the Shares received on exercise to exercise the Option with respect to additional Shares; (v) consideration received by the Company under a cashless exercise arrangement (whether through a broker or otherwise) implemented by the Company for the exercise of Options that has been approved by the Board or a Committee of Directors; (vi) consideration received by the Company under a net exercise program under which Shares are withheld from otherwise deliverable Shares that has been approved by the Board or a Committee of Directors; and (vii) any other consideration or method of payment to issue Shares (provided that other forms of considerations may only be approved by the Board or a Committee of Directors). (d) Incentive Stock Option Limitations. (i) The Exercise Price of an Incentive Stock Option may not be less than 100% of the Fair Market Value on the Grant Date. (ii) To the extent that the aggregate fair market value of the shares with respect to which incentive stock options under Code Section 422(b) are exercisable for the first time by a Participant during any calendar year (under all plans and agreements of the Company Group) exceeds $100,000, the incentive stock options whose value exceeds $100,000 will be treated as nonstatutory stock options. Incentive stock options will be considered in the order in which they were granted. For this purpose the fair market value of the shares subject to an option will be determined as of the grant date of each option. - 7 - (iii) The Expiration Date of an Incentive Stock Option will be the day prior to the 10th anniversary of the Grant Date or any earlier date provided in the Award Agreement, subject to clause (iv) below. power of all classes of stock of the Company or any Parent or Subsidiary of the Company: (iv) The following rules apply to Incentive Stock Options granted to Participants who own stock representing more than 10% of the total combined voting (1) the Expiration Date of the Incentive Stock Option may not be after the day prior to the 5th anniversary of the Grant Date; and (2) the Exercise Price may not be less than 110% of the Fair Market Value on the Grant Date. If an Option is designated in the Administrator action that granted it as an Incentive Stock Option but the terms of the Option do not comply with Sections 4(d)(iv)(1) and 4(d)(iv)(2), then the Option will not qualify as an Incentive Stock Option. All Options granted under the Plan are Nonstatutory Stock Options unless specifically designated as Incentive Stock Options in the Award Agreement pursuant to which such Options are granted. (e) Exercise of Option. An Option is exercised when the Company receives: (i) a notice of exercise (in such form as the Administrator may specify from time to time) from the person entitled to exercise the Option and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable withholding taxes). Shares issued upon exercise of an Option will be issued in the name of the Participant. Until the Shares are issued (as evidenced by the entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to an Option, despite the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. An Option may not be exercised for a fraction of a Share. Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for purchase under the Option, by the number of Shares as to which the Option is exercised. (f) Expiration of Options. Subject to Section 4(d), an Option’s Expiration Date will be set forth in the Award Agreement. An Option may expire before its expiration date under Sections 14 or 16(b) or under the Award Agreement. (g) Tolling of Expiration. If exercising an Option prior to its expiration is not permitted because of Applicable Laws, other than the rules of any stock exchange or quotation system on which the Common Stock is listed or quoted, the Option will remain exercisable until 30 days after the first date on which exercise would no longer be prevented by such provisions. If this would result in the Option remaining exercisable past its Expiration Date, then it will remain exercisable only until the end of the later of (x) the first day on which its exercise would not be prevented by Section 19(a) and (y) its Expiration Date. - 8 - 5. Restricted Stock. (a) Restricted Stock Award Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the Period of Restriction (if any), the number of Shares granted, and such other terms and conditions as the Administrator determines. Unless the Administrator determines otherwise, Shares of Restricted Stock will be held in escrow until the end of the Period of Restriction applicable to such Shares. All grants of Restricted Stock and interpretative decisions about Restricted Stock may only be made by the Administrator. (b) Restrictions: (i) Except as provided in this Section 5 or the Award Agreement, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated until the end of the Period of Restriction applicable to such Shares. (ii) During the Period of Restriction, Service Providers holding Shares of Restricted Stock may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise. (iii) During the Period of Restriction, Service Providers holding Shares of Restricted Stock will not be entitled to receive dividends and other distributions paid with respect to such Shares, unless the Administrator provides otherwise. If the Administrator provides that dividends and distributions will be received and any such dividends or distributions are paid in cash they will be subject to the same provisions regarding forfeitability as the Shares of Restricted Stock with respect to which they were paid and if such dividend or distributions are paid in Shares, the Shares will be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid and, unless the Administrator determines otherwise, the Company will hold such Shares until the restrictions on the Shares of Restricted Stock with respect to which they were paid have lapsed. (iv) Except as otherwise provided in this Section 5 or an Award Agreement, Shares of Restricted Stock covered by each Restricted Stock Award made under the Plan will be released from escrow when practicable after the last day of the applicable Period of Restriction. (v) The Administrator may impose, prior to grant, or remove any restrictions on Shares of Restricted Stock. 6. Restricted Stock Units. (a) Restricted Stock Unit Award Agreement. Each Award of Restricted Stock Units will be evidenced by an Award Agreement that will specify the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units. (b) Vesting Criteria and Other Terms. The Administrator will set vesting criteria that, depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units paid out to the Participant. The Administrator may set vesting criteria based upon the achievement of Company-wide, divisional, business unit, or individual goals (that may include continued employment or service) or any other basis determined by the Administrator in its sole discretion. - 9 - (c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will have earned the Restricted Stock Units and will be paid as determined in Section 6(d). The Administrator may reduce or waive any criteria that must be met to earn the Restricted Stock Units. (d) Form and Timing of Payment. Payment of earned Restricted Stock Units will be made when practicable after the date set forth in the Award Agreement and determined by the Administrator. The Administrator may settle earned Restricted Stock Units in cash, Shares, or a combination of both. 7. Stock Appreciation Rights. (a) Stock Appreciation Right Award Agreement. Each Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify the Exercise Price (which may not be less than 100% of Fair Market Value on the Grant Date), its Expiration Date, the conditions of exercise, and such other terms and conditions as the Administrator determines. (b) Payment of Stock Appreciation Right Amount. When a Participant exercises a Stock Appreciation Right, he or she will be entitled to receive a payment from the Company equal to: (i) the difference between the Fair Market Value on the date of exercise and the Exercise Price multiplied by (ii) the number of Shares with respect to which the Stock Appreciation Right is exercised. Payment upon Stock Appreciation Right exercise may be made in cash, in Shares of equivalent value, or any combination of cash and Shares, with the determination of form of payment made by the Administrator. Shares issued upon exercise of a Stock Appreciation Right will be issued in the name of the Participant. Until Shares are issued (as evidenced by the entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to a Stock Appreciation Right, despite the exercise of the Stock Appreciation Right. The Company will issue (or cause to be issued) such Shares promptly after the Stock Appreciation Right is exercised. A Stock Appreciation Right may not be exercised for a fraction of a Share. Exercising a Stock Appreciation Right in any manner will decrease (x) the number of Shares thereafter available under the Stock Appreciation Right by the number of Shares as to which the Stock Appreciation Right is exercised and (y) the number of Shares thereafter available under the Plan by the number of Shares issued upon such exercise. (c) Expiration of Stock Appreciation Rights. A Stock Appreciation Right’s Expiration Date will be set forth in the Award Agreement. A Stock Appreciation Right may expire before its expiration date under Sections 14 or 16(b) or under the Award Agreement. - 10 - (d) Tolling of Expiration. If exercising an Stock Appreciation Right prior to its expiration is not permitted because of Applicable Laws, other than the rules of any stock exchange or quotation system on which the Common Stock is listed or quoted, the Stock Appreciation Right will remain exercisable until 30 days after the first date on which exercise would no longer be prevented by such provisions. If this would result in the Stock Appreciation Right remaining exercisable past its Expiration Date, then it will remain exercisable only until the end of the later of (x) the first day on which its exercise would not be prevented by Section 19(a) and (y) its Expiration Date. 8. Performance Stock Units and Performance Shares. (a) Award Agreement. Each Award of Performance Stock Units/Shares will be evidenced by an Award Agreement that will specify the time period during which the performance objectives or other vesting provisions will be measured which shall not exceed 5 years (“Performance Period”) and the material terms of the Award. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, business unit or individual goals (including, but not limited to, continued employment or service) or any other basis determined by the Administrator. (b) Value of Performance Stock Units/Shares. Each Performance Stock Unit will have an initial value established by the Administrator on or before the Grant Date. Each Performance Share will have an initial value equal to the Fair Market Value on the Grant Date. (c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions (that may include continued employment or service). These objectives or vesting provisions may determine the number or value of Performance Stock Units/Shares paid out. (d) Earning of Performance Stock Units/Shares. After an applicable Performance Period has ended, the holder of Performance Stock Units/Shares will be entitled to receive a payout of the number of Performance Stock Units/Shares earned by the Participant over the Performance Period. The Administrator may reduce or waive any performance objectives or other vesting provisions for such Performance Stock Unit/Share. (e) Payment of Performance Stock Units/Shares. Payment of earned Performance Stock Units/Shares will be made when practicable after the end of the applicable Performance Period. Payment with respect to earned Performance Stock Units/Shares may be made in cash, in Shares of equivalent value, or any combination of cash and Shares, with the determination of form of payment made by the Administrator. 9. Performance Awards. (a) Award Agreement. Each Performance Award will be evidenced by an Award Agreement that will specify the Performance Period and the material terms of the Award. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, business unit or individual goals (including, but not limited to, continued employment or service) or any other basis determined by the Administrator. - 11 - (b) Value of Performance Awards. Each Performance Award’s threshold, target, and maximum payout values will be established by the Administrator on or before the Grant Date. (c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions (that may include continued employment or service). These objectives or vesting provisions will determine the value of the payout for the Performance Awards. (d) Earning of Performance Awards. After an applicable Performance Period has ended, the holder of a Performance Award will be entitled to receive a payout for the Performance Award earned by the Participant over the Performance Period. The Administrator may reduce or waive any performance objectives or other vesting provisions for such Performance Award. (e) Payment of Performance Awards. Payment of earned Performance Awards will be made when practicable after the end of the applicable Performance Period. Payment with respect to earned Performance Awards will be made in cash, in Shares of equivalent value, or any combination of cash and Shares, with the determination of form of payment made by the Administrator at the time of payment. 10. Outside Director Limitations. No Outside Director may be granted, in any Fiscal Year, Awards with a grant date fair value (determined under U.S. generally accepted accounting principles) of more than $1,000,000, increased to $2,000,000 in connection with his or her initial service as an Outside Director. Awards granted to an individual while he or she was an Employee, or while he or she was a Consultant but not an Outside Director, will not count for purpose of this limitation. 11. Leaves of Absence/Transfer Between Locations/Change of Status. (a) General. Unless otherwise provided by the Administrator, a Participant will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or other member of the Company Group employing such Employee or (ii) any transfer between locations of the Company or members of the Company Group. (b) Vesting. Unless a leave policy approved by the Administrator provides otherwise or it is otherwise required by Applicable Law, vesting of Awards granted under the Plan will continue only for Participants on an approved leave of absence. (c) Incentive Stock Option Status. If a Participant’s leave of absence approved by the Company or other member of the Company Group employing such Employee exceeds 3 months and reemployment upon expiration of such leave is not guaranteed by statute or contract, then 3 months following the 1st day of such leave the Participant will no longer be an employee for incentive stock option purposes. If reemployment upon expiration of such leave of absence is not guaranteed by statute or contract, then 6 months following the 1st day of such leave any Incentive Stock Option held by the Participant will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option. - 12 - (d) Protected Leaves. (i) Any leave of absence by a Participant will be subject to any Applicable Laws that apply to leaves of absence. (ii) For a Participant on a military leave, if required by Applicable Laws, vesting will continue for the longest period that vesting continues under any other statutory or Company-approved leave of absence. When a Participant returns from military leave (under conditions that would entitle him or her to such protection under the Uniformed Services Employment and Reemployment Rights Act), the Participant will be given vesting credit to the same extent as if the Participant had continued to provide services to the Company or other member of the Company Group, as applicable, through the military leave. (e) Changes in Status. If a Participant who is an Employee has a reduction in hours worked, the Administrator may unilaterally: after the date of such extend leave or reduction in hours; and (i) make a corresponding reduction in the number of Shares or cash amount subject to any portion of an Award that is scheduled to vest or become payable (ii) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to such Award. If any such reduction occurs, the Participant will have no right to any portion of the Award that is reduced. (f) Determinations. The effect of a Company-approved leave of absence, a transfer, or a Participant’s reduction in hours of employment or service on the vesting of an Award shall be determined, under policies reviewed by the Administrator, by the Company’s senior human resources officer or other person performing that function or, with respect to Directors or Officers by the Compensation Committee of the Board, and any such determination will be final. 12. Transferability of Awards. (a) General Rule. Unless determined otherwise by the Administrator, or otherwise required by Applicable Laws, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant. If the Administrator makes an Award transferable, the Award will be limited by any additional terms and conditions imposed by the Administrator. Any unauthorized transfer of an Award will be void. (b) Domestic Relations Orders. If approved by the Administrator, an Award may be transferred under a domestic relations order, official marital settlement agreement or other divorce or separation instrument as permitted by Treasury Regulations Section 1.421-1(b)(2). An Incentive Stock Option may be converted into a Nonstatutory Stock Option as a result of such transfer. (c) Limited Transfers for the Benefit of Family Members. The Administrator may permit an Award or Share issued under this Plan to be assigned or transferred subject to the applicable limitations, set forth in the General Instructions to Form S-8 Registration Statement under the Securities Act, if applicable, and any other Applicable Laws. - 13 - (d) Permitted Transferees. Any individual or entity to whom an Award is transferred will be subject to all of the terms and conditions applicable to the Participant who transferred the Award, including the terms and conditions in this Plan and the Award Agreement. If an Award is unvested then the service of the Participant will continue to determine whether the Award will vest and any Expiration Date. 13. Adjustments; Dissolution or Liquidation. (a) Adjustments. If any extraordinary dividend or other extraordinary distribution (whether in cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, issuance of warrants or other rights to acquire securities of the Company, other change in the corporate structure of the Company affecting the Shares, or any similar equity restructuring transaction, as that term is used in Statement of Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any of its successors) affecting the Shares occurs (including, without limitation, a Change in Control), the Administrator, to prevent diminution or enlargement of the benefits or potential benefits intended to be provided under the Plan, will adjust the number and class of shares that may be delivered under the Plan and/or the number, class, and price of shares covered by each outstanding Award, and the numerical Share limits in Section 2 in such a manner as it deems equitable. Notwithstanding the foregoing, the conversion of any convertible securities of the Company and ordinary course repurchases of shares or other securities of the Company will not be treated as an event that will require adjustment. (b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify each Participant when practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the consummation of such proposed action. 14. Change in Control. (a) Administrator Discretion. If a Change in Control or a merger of the Company with or into another corporation or other entity occurs, each outstanding Award will be treated as the Administrator determines, including, without limitation, that such Award be continued by the successor corporation or a Parent or Subsidiary of the successor corporation. (b) Identical Treatment Not Required. The Administrator need not take the same action or actions with respect to all Awards or portions thereof or with respect to all Participants. The Administrator may take different actions with respect to the vested and unvested portions of an Award. The Administrator will not be required to treat all Awards similarly in the transaction. - 14 - (c) Continuation. An Award will be considered continued if, following the Change in Control or merger: (i) the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the transaction, the consideration (whether stock, cash, or other securities or property) received in the transaction by holders of Shares for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration received by the holders of a majority of the outstanding Shares); provided that if the consideration received in the transaction is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon exercising an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, Performance Stock Unit, Performance Share or Performance Award, for each Share subject to such Award, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the transaction; or (ii) the Award is terminated in exchange for an amount of cash and/or property, if any, equal to the amount that would have been attained upon the exercise of such Award or realization of the Participant’s rights as of the date of the occurrence of the transaction. Any such cash or property may be subjected to any escrow applicable to holders of Common Stock in the Change of Control. If as of the date of the occurrence of the transaction the Administrator determines that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment. The amount of cash or property can be subjected to vesting and paid to the Participant over the original vesting schedule of the Award. (iii) Notwithstanding anything in this Section 14(c) to the contrary, an Award that vests, is earned or paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies any of such performance goals without the Participant’s consent; provided, however, a modification to such performance goals only to reflect the successor corporation’s post-transaction corporate structure will not invalidate an otherwise valid Award assumption. (d) The Administrator will have authority to modify Awards in connection with a Change in Control or merger: (i) in a manner that causes them to lose their tax-preferred status, (ii) to terminate any right a Participant has to exercise an Option prior to vesting in the Shares subject to the Option (i.e., “early exercise”), so that following the closing of the transaction the Option may only be exercised to the extent it is vested; (iii) to reduce the Exercise Price subject to the Award in a manner that is disproportionate to the increase in the number of Shares subject to the Award, as long as the amount that would be received upon exercise of the Award immediately before and immediately following the closing of the transaction is equivalent and the adjustment complies with Treasury Regulation Section 1.409A-1(b)(v)(D); and (iv) to suspend a Participant’s right to exercise an Option during a limited period of time preceding and or following the closing of the transaction without Participant consent if such suspension is administratively necessary or advisable to permit the closing of the transaction. - 15 - (e) Non-Continuation. If the successor corporation does not continue for an Award (or some portion such Award), the Participant will fully vest in (and have the right to exercise) 100% of the then-unvested Shares subject to his or her outstanding Options and Stock Appreciation Rights, all restrictions on 100% of the Participant’s outstanding Restricted Stock and Restricted Stock Units will lapse, and, regarding 100% of Participant’s outstanding Awards with performance-based vesting, all performance goals or other vesting criteria will be treated as achieved at 100% of target levels and all other terms and conditions met. In no event will vesting of an Award accelerate as to more than 100% of the Award. If Options or Stock Appreciation Rights are not continued when a Change in Control or a merger of the Company with or into another corporation or other entity occurs, the Administrator will notify the Participant in writing or electronically that the Participant’s vested Options or Stock Appreciation Rights (after considering the foregoing vesting acceleration, if any) will be exercisable for a period of time determined by the Administrator in its sole discretion and all of the Participant’s Options or Stock Appreciation Rights will terminate upon the expiration of such period (whether vested or unvested). (f) Outside Director Awards. With respect to Awards granted to an Outside Director that are continued, if on the date of or following such continuation the Participant’s status as a Director or a director of the successor corporation, as applicable, is terminated other than upon a voluntary resignation by the Participant that is not at the request of the acquirer, then the Participant will fully vest in and have the right to exercise Options and/or Stock Appreciation Rights as to all of the Shares underlying such Award, including those Shares not otherwise vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, all performance goals or other vesting criteria will be treated as achieved at 100% of target levels and all other terms and conditions met. 15. Tax Matters. (a) Withholding Requirements. Prior to the delivery of any Shares or cash under an Award (or exercise thereof) or such earlier time as any tax withholding obligations are due, the Company may deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy any taxes (including the Participant’s social tax obligations) required to be withheld with respect to such Award (or exercise thereof). (b) Withholding Arrangements. The Administrator, in its sole discretion and under such procedures as it may specify from time to time, may permit or may require a Participant to satisfy such tax withholding obligations, in whole or in part by (without limitation) (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable cash (including cash from the sale of Shares issued to Participant) or Shares having a fair market value equal to the minimum statutory amount required to be withheld or a greater amount if that would not result in unfavorable financial accounting treatment, (iii) delivering to the Company already-owned Shares having a fair market value equal to the minimum statutory amount required to be withheld, or (iv) requiring the Participant to engage in a cashless exercise transaction (whether through a broker or otherwise) implemented by the Company in connection with the Plan. The fair market value of the Shares to be withheld or delivered will be determined as of the date the taxes must be withheld. (c) Compliance With Code Section 409A. Except as otherwise determined by the Administrator, it is intended that Awards will be designed and operated so that they are either exempt from the application of Code Section 409A or comply with any requirements necessary to avoid the imposition of additional tax under Code Section 409A(a)(1)(B) so that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A and the Plan and each Award Agreement will be interpreted consistent with this intent. This Section 15(c) is not a guarantee to any Participant of the consequences of his or her Awards. - 16 - 16. Other Terms. (a) No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right regarding continuing the Participant’s relationship as a Service Provider with the Company or member of the Company Group, nor will they interfere with the Participant’s right, or the Participant’s employer’s right, to terminate such relationship with or without cause, to the extent permitted by Applicable Laws. (b) Forfeiture Events. (i) All Awards granted under the Plan will be subject to recoupment under any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other Applicable Laws. In addition, the Administrator may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Administrator determines necessary or appropriate, including but not limited to a reacquisition right regarding previously acquired Shares or other cash or property. Unless this Section 16(b) is specifically mentioned and waived in an Award Agreement or other document, no recovery of compensation under a clawback policy or otherwise will give a Participant the right to resign for “good reason” or “constructive termination” (or similar term) under any agreement with the Company. (ii) The Administrator may specify in an Award Agreement that the Participant’s rights, payments, and benefits with respect to an Award will be subject to reduction, cancellation, forfeiture, or recoupment upon the occurrence of specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. In the event of termination of such Participant’s status as Service Provider for Cause or any act by a Participant, whether before or after such Participant’s Termination Status Date, that would constitute cause for termination of such Participant’s status as a Service Provider, all Awards will terminate immediately. (iii) If the Company is required to prepare an accounting restatement due to the material noncompliance of the Company, as a result of misconduct, with any financial reporting requirement under securities laws, any Participant who (i) knowingly or through gross negligence engaged in the misconduct or who knowingly or through gross negligence failed to prevent the misconduct or (ii) is one of the individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002, must reimburse the Company the amount of any payment in settlement of an Award earned or accrued during the 12-month period following the first public issuance or filing with the United States Securities and Exchange Commission (whichever first occurred) of the financial document embodying such financial reporting requirement. - 17 - 17. Term of Plan. Subject to Section 20, the Plan will become effective upon the business day immediately prior to the Registration Date. It will continue in effect until terminated under Section 18, but no Incentive Stock Options may be granted after 10 years from the date the Plan is adopted by the Board and Section 2(b) will operate only until the 10th anniversary of the date the Plan is adopted by the Board. 18. Amendment and Termination of the Plan. (a) Amendment and Termination. The Board or Compensation Committee of the Board may amend, alter, suspend or terminate the Plan. (b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary or desirable to comply with Applicable Laws. (c) Consent of Participants Generally Required. Subject to Section 18(d) below, no amendment, alteration, suspension or termination of the Plan or an Award under it will materially impair the rights of any Participant without a signed, written agreement between the Participant and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it regarding Awards granted under the Plan prior to such termination. (d) Exceptions to Consent Requirement. (i) A Participant’s rights will not be deemed to have been impaired by any amendment, alteration, suspension or termination if the Administrator, in its sole discretion, determines that the amendment, alteration, suspension or termination taken as a whole, does not materially impair the Participant’s rights; and (ii) Subject to any limitations of Applicable Laws, the Administrator may amend the terms of any one or more Awards without the affected Participant’s consent even if it does materially impair the Participant’s right if such amendment is done (1) in a manner permitted under the Plan, (2) to maintain the qualified status of the Award as an Incentive Stock Option under Code Section 422, the Award as an Incentive Stock Option under Code Section 422, (3) to change the terms of an Incentive Stock Option, if such change results in impairment of the Award only because it impairs the qualified status of (4) to clarify the manner of exemption from Code Section 409A or compliance with any requirements necessary to avoid the imposition of additional tax under Code Section 409A(a)(1)(B), or (5) to comply with other Applicable Laws. - 18 - 19. Conditions Upon Issuance of Shares. (a) Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares will comply with Applicable Laws. If required by the Administrator, issuance will be further subject to the approval of counsel for the Company with respect to such compliance. The inability of the Company to obtain authority from any regulatory body having jurisdiction or to complete or comply with the requirements of any Applicable Laws will relieve the Company of any liability regarding the failure to issue or sell such Shares as to which such authority, registration, qualification or rule compliance was not obtained and the Administrator reserves the authority, without the consent of a Participant, to terminate or cancel Awards with or without consideration in such a situation. (b) Investment Representations. As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent and warrant during any such exercise that the Shares are being purchased only for investment and with no present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required. (c) Failure to Accept Award. If a Participant has not accepted an Award or has not taken all administrative and other steps (e.g. setting up an account with a broker designated by the Company) necessary for the Company to issue Shares upon the vesting, exercise, or settlement of the Award prior to the first date the Shares subject such Award are scheduled to vest, then the Award will be cancelled on such date and the Shares subject to such Award immediately will revert to the Plan for no additional consideration unless otherwise provided by the Administrator. 20. Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within 12 months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws. 21. Definitions.

The Participant acknowledges that a waiver by the Company of a breach of any provision of this Agreement will not operate or be construed as a waiver of any other provision of this Agreement or of any subsequent breach of this Agreement by him or her. - 7 - EXHIBIT B APPENDIX TO RESTRICTED STOCK UNIT AGREEMENT Terms and Conditions This Appendix to Restricted Stock Unit Agreement (the “Appendix”) includes additional terms and conditions that govern these RSUs granted to the Participant under the Plan if he or she resides in one of the countries listed below on the Grant Date or he or she moves to one of the listed countries. Notifications This Appendix may also include information regarding exchange controls and certain other issues of which the Participant should be aware with respect to participation in the Plan. The information is based on the securities, exchange control, and other Applicable Laws in effect in the respective countries as of September 1, 2017. Such Applicable Laws are often complex and change frequently. As a result, the Company strongly recommends that the Participant not rely on the information in this Appendix as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the Participant sells Shares acquired under the Plan. In addition, the information contained in this Appendix is general in nature and may not apply to the Participant’s particular situation, and the Company is not in a position to assure him or her of a particular result. The Participant is advised to seek appropriate professional advice as to how the Applicable Laws in his or her country may apply to his or her situation. Finally, if the Participant is a citizen or resident of a country other than the one in which he or she is currently working, transfers employment after these RSUs are granted, or is considered a resident of another country for local law purposes, the information in this Appendix may not apply to him or her, and the Administrator will determine to what extent the terms and conditions in this Appendix apply. - 1 - GENPREX, INC. EMPLOYEE STOCK OPTION GRANT NOTICE AND OPTION AGREEMENT As a key leader in our business, you are in a position to have significant influence on the performance and success of Genprex, Inc. (the “Company”). I am pleased to inform you that, in recognition of the role you play in our collective success, you have been granted an option to purchase shares of the Company’s Common Stock. This award is subject to the terms and conditions of the following Grant Notice and Stock Option Agreement. Although this award is made outside of the Genprex, Inc. 2018 Equity Incentive Plan (the “Plan”), the terms of the Plan are incorporated herein by reference in accordance with Section A hereof as if the Option were granted under the Plan. The details of this award are indicated below. Exhibit 10.4 Optionee: Date of Grant: Number of Shares subject to the Option: Exercise Price Per Share: Type of Option: Term of Option Vesting: Nonqualified Stock Option Ten (10) years Your right to exercise this Option shall vest in three (3) equal installments on each of the first three anniversaries of the Date of Grant (each such date, a “Vesting Date”), in each case subject to your continuing to provide services to the Company through the applicable Vesting Dates. ______________________________________ Name: Rodney Varner Title: President and Chief Executive Officer Acknowledged and agreed as of the Date of Grant ________________________________________ Name: STOCK OPTION AGREEMENT THIS STOCK OPTION AGREEMENT (together with the above grant notice (the “Grant Notice”), the “Agreement”) is made and entered into as of the date set forth on the Grant Notice by and between Genprex, Inc., a Delaware corporation (the “Company”), and the individual (the “Optionee”) set forth on the Grant Notice. A. The Company has determined that it is to the advantage and best interest of the Company to grant to the Optionee an option to purchase the number of Shares (the “Shares”) set forth on the Grant Notice, at the exercise price per Share set forth on the Grant Notice (the “Option”). The Option constitutes a grant made to qualify as an inducement award pursuant to NASDAQ Listing Rule 5635(c) and is not subject to the Plan. However, any provision of the Plan, as it may be amended from time to time, that is not inconsistent with this Agreement is hereby incorporated herein by reference as if this Agreement and Option were entered into/granted under the Plan. By entering into this Agreement, the Optionee agrees and acknowledges that Optionee has received and read a copy of the Plan as set forth in Exhibit A hereto. In the event of any inconsistency between the Plan and this Agreement, the terms of this Agreement shall control. B. Unless otherwise defined herein, capitalized terms used in this Agreement shall have the meanings set forth in the Plan. NOW, THEREFORE, in consideration of the mutual agreements contained herein, the Optionee and the Company hereby agree as follows: 1. Acceptance of Agreement. Optionee has reviewed all of the provisions of the Plan, the Grant Notice and this Agreement. By accepting this Option, Optionee hereby agrees that this Option is granted under and governed by the terms and conditions of the Grant Notice and this Agreement. The Optionee’s electronic signature of this Agreement shall have the same validity and effect as a signature affixed by hand. 2. Grant and Terms of Stock Option. 1. Grant of Option. Pursuant to this Agreement, the Company has granted to the Optionee the right and option to purchase, subject to the terms and conditions set forth in the Plan and this Agreement, all or any part of the number of Shares set forth on the Grant Notice at a purchase price per Share equal to the exercise price per Share set forth on the Grant Notice. An Option granted pursuant to the Grant Notice and this Agreement shall be a Nonqualified Stock Option. 2. Vesting and Term of Option. This Section 2.2 is subject to the provisions of the Plan and the other provisions of this Agreement. 1. This Option shall vest and become exercisable as described in the Grant Notice. 2. The “Term” of this Option shall begin on the Date of Grant set forth in the Grant Notice and end on the expiration of the Term specified in the Grant Notice. No portion of this Option may be exercised after the expiration of the Term. 3. For the purposes of this Agreement, “Termination” shall mean the termination of the employment or service of the Optionee with the Company and all Affiliates thereof (including because of the Optionee’s employer ceasing to be an affiliate of the Company). For purposes of this Agreement, Termination will not occur when Optionee goes on a military leave, a sick leave or another bona fide leave of absence that was approved by the Company in writing if the terms of the leave provide for continued service crediting, or when continued service crediting is required by Applicable Laws. Notwithstanding the foregoing, an approved leave of absence for six months or less, which does not in fact exceed six months, will not result in Termination for purposes of this Agreement. However, Termination will occur when an approved leave described in this Section A ends, unless Optionee immediately returns to active work. 4. In the event of Optionee’s Termination for any reason (including death or Disability) other than Optionee’s Termination for Cause: 1. the portion of this Option that is not vested and exercisable as of the Termination of Status Date shall not continue to vest and shall be immediately cancelled and terminated; and 2. the portion of this Option that is vested and exercisable as of the Termination of Status Date shall terminate and be cancelled on the earlier of: a. the expiration of the Term and b. one (1) year after such Termination of Status Date. 5. In the event of Optionee’s Termination for Cause, or if, after the Termination, the Administrator determines that Cause existed before such Termination, this entire Option shall not continue to vest, shall be cancelled and terminated as of the Termination of Status Date, and shall no longer be exercisable as to any Shares, whether or not previously vested. 3. Method of Exercise. 1. Method of Exercise. Each election to exercise the Option shall be subject to the terms and conditions of the Plan and shall be in writing, signed by the Optionee or by his or her executor, administrator, or permitted transferee (subject to any restrictions provided under the Plan), made pursuant to and in accordance with the terms and conditions set forth in the Plan and received by the Company at its principal offices, accompanied by payment in full as provided in the Plan or in this Agreement. Notwithstanding any of the foregoing, the Administrator shall have the right to specify all conditions of the manner of exercise. Upon the Company’s determination that the Option has been validly exercised as to any of the Shares, the Company may issue certificates in the Optionee’s name for such Shares. However, the Company shall not be liable to the Optionee for damages relating to any reasonable delays in issuing the certificates to the Optionee, any loss of the certificates, or any mistakes or errors in the issuance of the certificates or in the certificates themselves which it promptly undertakes to correct. 2. Restrictions on Exercise. No Shares will be issued pursuant to the exercise of this Option unless and until there shall have been full compliance with all applicable requirements of the Securities Act, as amended (whether by registration or satisfaction of exemption conditions), all applicable listing requirements of any national securities exchange or other market system on which the Common Stock is then listed and all applicable requirements of any Applicable Laws and of any regulatory bodies having jurisdiction over such issuance. As a condition to the exercise of this Option, the Company may require the Optionee to make any representation and warranty to the Company as may be necessary or appropriate, in the judgment of the Administrator, to comply with any Applicable Law. In addition, Optionee shall not sell any Shares acquired upon exercise of this Option at a time when Applicable Laws, regulations or Company’s or underwriter trading policies prohibit such sale. Any other provision of this Agreement notwithstanding, the Company shall have the right to designate one or more periods of time, each of which shall not exceed 180 days in length, during which this Option shall not be exercisable if the Administrator determines (in its sole discretion) that such limitation on exercise could in any way facilitate a lessening of any restriction on transfer pursuant to the Securities Act or any state securities laws with respect to any issuance of securities by the Company, facilitate the registration or qualification of any securities by the Company under the Securities Act or any state securities laws, or facilitate the perfection of any exemption from the registration or qualification requirements of the Securities Act or any applicable state securities laws for the issuance or transfer of any securities. Such limitation on exercise shall not alter the vesting schedule set forth in this Agreement other than to limit the periods during which this Option shall be exercisable. 3. Method of Payment. Payment of the exercise price shall be made in full at the time of exercise (a) by the delivery of cash or check acceptable to the Administrator, including an amount to cover the withholding taxes (as provided in Section 7.11) with respect to such exercise, or (b) any other method, if any, approved by the Administrator, including (i) by means of consideration received under any cashless exercise procedure, if any, approved by the Administrator (including the withholding of Shares otherwise issuable upon exercise) or (ii) any other form of consideration approved by the Administrator and permitted by Applicable Laws. 4. No Rights as a Shareholder. Until the Shares are issued to the Optionee (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder will exist with respect to the Shares, notwithstanding the exercise of the Option. 4. Non-Transferability of Option. Except as provided below, this Option may not be sold, assigned transferred in any manner, pledged or otherwise encumbered other than by will or by the laws of descent or distribution or to a beneficiary designated pursuant to the Plan, and may be exercised during the lifetime of Optionee only by Optionee or the Optionee’s guardian or legal representative. Subject to all of the other terms and conditions of this Agreement, following the death of Optionee, this Option may, to the extent it is vested and exercisable by Optionee in accordance with its terms on the Termination of Status Date, be exercised by Optionee’s executor or administrator, or the person or persons to whom the Optionee’s rights under this Agreement shall pass by will or by the laws of descent and distribution as the case may be. Any heir or legatee of the Optionee shall take rights herein granted subject to the terms and conditions hereof. 5. Restrictions; Restrictive Legends. Ownership and transfer of Shares issued pursuant to the exercise of this Option will be subject to the provisions of, including ownership and transfer restrictions contained in, the Company’s Certificate of Incorporation or Bylaws, as amended from time to time, restrictions imposed by Applicable Laws and restrictions set forth or referenced in legends imprinted on certificates representing such Shares. 6. Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, to the extent that this Option had not been previously exercised, it will terminate immediately prior to the consummation of such proposed dissolution or liquidation. In such instance, the Administrator may, in the exercise of its sole discretion, declare that this Option will terminate as of a date fixed by the Administrator and give the Optionee the right to exercise this Option prior to such date as to all or any part of the optioned stock, including Shares as to which this Option would not otherwise be exercisable. 7. General. 1. Governing Law. This Agreement shall be governed by and construed under the laws of the State of Delaware applicable to agreements made and to be performed entirely in Delaware, without regard to the conflicts of law provisions of Delaware or any other jurisdiction. 2. Community Property. Without prejudice to the actual rights of the spouses as between each other, for all purposes of this Agreement, the Optionee shall be treated as agent and attorney-in-fact for that interest held or claimed by his or her spouse with respect to this Option and the parties hereto shall act in all matters as if the Optionee was the sole owner of this Option. This appointment is coupled with an interest and is irrevocable. 3. No Employment Rights. Nothing herein contained shall be construed as an agreement by the Company or any of its Subsidiaries, express or implied, to employ the Optionee or contract for the Optionee’s services, to restrict the Company’s or such Subsidiary’s right to discharge the Optionee or cease contracting for the Optionee’s services or to modify, extend or otherwise affect in any manner whatsoever the terms of any employment agreement or contract for services which may exist between the Optionee and the Company or any affiliate. 4. Application to Other Stock. In the event any capital stock of the Company or any other corporation shall be distributed on, with respect to, or in exchange for Shares as a stock dividend, stock split, reclassification or recapitalization in connection with any merger or reorganization or otherwise, all restrictions, rights and obligations set forth in this Agreement shall apply with respect to such other capital stock to the same extent as they are, or would have been applicable, to the Shares on or with respect to which such other capital stock was distributed, and references to “Company” in respect of such distributed stock shall be deemed to refer to the company to which such distributed stock relates. 5. No Third-Party Benefits. Except as otherwise expressly provided in this Agreement, none of the provisions of this Agreement shall be for the benefit of, or enforceable by, any third-party beneficiary. 6. Successors and Assigns. Except as provided herein to the contrary, this Agreement shall be binding upon and inure to the benefit of the parties, their respective successors and permitted assigns. 7. No Assignment. Except as otherwise provided in this Agreement, the Optionee may not assign any of his or her rights under this Agreement without the prior written consent of the Company, which consent may be withheld in its sole discretion. The Company shall be permitted to assign its rights or obligations under this Agreement so long as such assignee agrees to perform all of the Company’s obligations hereunder. 8. Severability. The validity, legality or enforceability of the remainder of this Agreement shall not be affected even if one or more of the provisions of this Agreement shall be held to be invalid, illegal or unenforceable in any respect. 9. Equitable Relief. The Optionee acknowledges that, in the event of a threatened or actual breach of any of the provisions of this Agreement, damages alone will be an inadequate remedy, and such breach will cause the Company great, immediate and irreparable injury and damage. Accordingly, the Optionee agrees that the Company shall be entitled to injunctive and other equitable relief, and that such relief shall be in addition to, and not in lieu of, any remedies it may have at law or under this Agreement. 10. Jurisdiction. Any suit, action or proceeding with respect to this Agreement, or any judgment entered by any court in respect of any thereof, shall be brought in any court of competent jurisdiction in the State of Texas, and the Company and the Optionee hereby submit to the exclusive jurisdiction of such courts for the purpose of any such suit, action, proceeding or judgment. The Optionee and the Company hereby irrevocably waive (i) any objections which it may now or hereafter have to the laying of the venue of any suit, action or proceeding arising out of or relating to this Agreement brought in any court of competent jurisdiction in the State of Texas, (ii) any claim that any such suit, action or proceeding brought in any such court has been brought in any inconvenient forum and (iii) any right to a jury trial. 11. Taxes. By agreeing to this Agreement, the Optionee represents that he or she has reviewed with his or her own tax advisors the federal, state, local and foreign tax consequences of the transactions contemplated by this Agreement and that he or she is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. The Company shall be entitled to require a cash payment by or on behalf of the Optionee and/or to deduct from the Shares or cash otherwise issuable hereunder or other compensation payable to the Optionee the minimum amount of any sums required by federal, state or local tax law to be withheld (or other such sums that will not cause adverse accounting consequences for the Company and is permitted under applicable withholding rules promulgated by the Internal Revenue Service or another applicable governmental entity) in respect of the Option, its exercise or any payment or transfer under or with respect to the Option. 12.

Complete Agreement. The Grant Notice, this Stock Option Agreement, the Plan, and the applicable provisions (if any) contained in a written employment agreement between the Company or an affiliate and the Optionee constitute the parties’ entire agreement with respect to the subject matter hereof and supersede all agreements, representations, warranties, statements, promises and understandings, whether oral or written, with respect to the subject matter hereof. 17.

If it is determined that the terms of this Agreement have been structured in a manner that would result in adverse tax treatment under Section 409A of the Code, the parties agree to cooperate in taking all reasonable measures to restructure the arrangement to minimize or avoid such adverse tax treatment without materially impairing Optionee’s economic rights. 20. Waiver of Jury Trial. TO THE EXTENT EITHER PARTY INITIATES LITIGATION INVOLVING THIS AGREEMENT OR ANY ASPECT OF THE RELATIONSHIP BETWEEN US (EVEN IF OTHER PARTIES OR OTHER CLAIMS ARE INCLUDED IN SUCH LITIGATION), ALL OF THE PARTIES WAIVE THEIR RIGHT TO A TRIAL BY JURY.

Optionee hereby consents to receive such documents delivered electronically or to retrieve such documents furnished electronically (including on EDGAR), as applicable, and agrees to participate in the Plan through any online or electronic system established and maintained by the Company or another third party designated by the Company. 22. Section 409A.

Any payments that qualify for the “short-term deferral” exception or another exception under Section 409A of the Code shall be paid under the applicable exception. For purposes of the limitations on nonqualified deferred compensation under Section 409A of the Code, each payment of compensation under this Agreement shall be treated as a separate payment of compensation. Notwithstanding anything contained herein to the contrary, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A of the Code, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to this Agreement during the six-month period immediately following the Participant’s separation from service shall instead be paid on the first business day after the date that is six months following the Participant’s termination date (or death, if earlier). EXHIBIT A [Genprex, Inc. 2018 Equity Incentive Plan] Exhibit 10.24 CERTAIN IDENTIFIED INFORMATION MARKED WITH “[***]” HAS BEEN EXCLUDED FROM THIS EXHIBIT BECAUSE IT IS BOTH NOT MATERIAL AND IS THE TYPE THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL.

COMPENSATION RECOVERY POLICY (Adopted and approved as of November 27, 2023) Exhibit 97.1 1. Purpose Genprex, Inc. (the “Company”) is committed to promoting high standards of honest and ethical business conduct and compliance with applicable laws, rules and regulations. As part of this commitment, the Company has adopted this Compensation Recovery Policy (this “Policy”). This Policy is designed to comply with the requirements of Section 10D of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Rule 10D-1 promulgated thereunder and the rules of the national securities exchange on which the Company’s securities are traded and explains when the Company will pursue recovery of Incentive Compensation awarded or paid to a Covered Person. Please refer to Exhibit A attached hereto (the “Definitions Exhibit”) for the definitions of capitalized terms used throughout this Policy. 2. Recovery of Recoverable Incentive Compensation In the event of a Restatement, the Company will pursue, reasonably promptly, recovery of all Recoverable Incentive Compensation from a Covered Person without regard to such Covered Person’s individual knowledge or responsibility related to the Restatement. Notwithstanding the foregoing, if the Company is otherwise required by this Policy to undertake a Restatement, the Company will not be required to recover the Recoverable Incentive Compensation if the Compensation Committee of the Board of Directors (the “Board”) of the Company (the “Compensation Committee”) determines, after exercising a normal due process review of all the relevant facts and circumstances, that (a) a Recovery Exception exists and (b) it would be impracticable to seek such recovery under such facts and circumstances. If such Recoverable Incentive Compensation was not awarded or paid on a formulaic basis, the Company will pursue recovery of the amount that the Compensation Committee determines in good faith should be recovered. 3. Other Actions The Compensation Committee may, subject to applicable law, pursue recovery of Recoverable Incentive Compensation in the manner it chooses, including by pursuing reimbursement from the Covered Person of all or part of the compensation awarded or paid, by electing to withhold unpaid compensation, by set-off, or by rescinding or canceling unvested stock or option awards. In the reasonable exercise of its business judgment under this Policy, the Compensation Committee may in its sole discretion determine whether and to what extent additional action is appropriate to address the circumstances surrounding a Restatement to minimize the likelihood of any recurrence and to impose such other discipline as it deems appropriate. 4. No Indemnification or Reimbursement As required by applicable law, notwithstanding the terms of any other policy, program, agreement or arrangement, in no event will the Company or any of its affiliates indemnify or reimburse a Covered Person for any loss of Recoverable Incentive Compensation under this Policy and, to the extent prohibited by law, neither the Company nor any of its affiliates will pay premiums on any insurance policy that would cover a Covered Person’s potential obligations with respect to Recoverable Incentive Compensation under this Policy. 5. Administration of Policy The Compensation Committee will have full authority to administer this Policy. The Compensation Committee will, subject to the provisions of this Policy and Rule 10D-1 of the Exchange Act, and the Company’s applicable exchange listing standards, make such determinations and interpretations and take such actions in connection with this Policy as it deems necessary, appropriate or advisable. It is intended that this Policy be interpreted in a manner that is consistent with the requirements of Section 10D of the Exchange Act, Rule 10D-1 thereunder and any applicable rules or standards adopted by the Securities and Exchange Commission or any national securities exchange on which the Company’s securities are listed. All determinations and interpretations made by the Compensation Committee will be final, binding and conclusive. 6. Other Claims and Rights The requirements of this Policy are in addition to, and not in lieu of, any legal and equitable claims the Company or any of its affiliates may have or any actions that may be imposed by law enforcement agencies, regulators, administrative bodies, or other authorities. Further, the exercise by the Compensation Committee of any rights pursuant to this Policy will not impact any other rights that the Company or any of its affiliates may have with respect to any Covered Person subject to this Policy. 7. Acknowledgement by Covered Persons; Condition to Eligibility for Incentive Compensation The Company will provide notice and seek acknowledgement of this Policy from each Covered Person, provided that the failure to provide such notice or obtain such acknowledgement will have no impact on the applicability or enforceability of this Policy. After the Effective Date (and also with respect to any Incentive Compensation Received on or after October 2, 2023 pursuant to a preexisting contract or arrangement), any grant of Incentive Compensation to a Covered Person will be deemed to have been made subject to the terms of this Policy, whether or not such Policy is specifically referenced in the documentation relating to such grant and this Policy shall be deemed to constitute an integral part of the terms of any such grant. All Incentive Compensation subject to this Policy will remain subject to this Policy, even if already paid, until the Policy ceases to apply to such Incentive Compensation and any other vesting conditions applicable to such Incentive Compensation are satisfied. 8. Amendment; Termination The Board or the Compensation Committee may amend or terminate this Policy at any time. In the event that Section 10D of the Exchange Act, Rule 10D-1 thereunder or the rules of the national securities exchange on which the Company’s securities are traded are modified or supplemented, whether by law, regulation or legal interpretation, such modification or supplement shall be deemed to modify or supplement this Policy to the maximum extent permitted by applicable law. 9. Effectiveness Except as otherwise determined in writing by the Compensation Committee, this Policy will apply to any Incentive Compensation that is Received by a Covered Person on or after the Effective Date. This Policy will survive and continue notwithstanding any termination of a Covered Person’s employment with the Company and its affiliates. 10. Successors This Policy shall be binding and enforceable against all Covered Persons and their successors, beneficiaries, heirs, executors, administrators, or other legal representatives. Exhibit A GENPREX, INC. DEFINITIONS EXHIBIT TO COMPENSATION RECOVERY POLICY “Applicable Period” means the three completed fiscal years of the Company immediately preceding the earlier of (i) the date the Board, a committee of the Board, or the officer or officers of the Company authorized to take such action if Board action is not required, concludes (or reasonably should have concluded) that a Restatement is required or (ii) the date a court, regulator, or other legally authorized body directs the Company to prepare a Restatement. The “Applicable Period” also includes any transition period (that results from a change in the Company’s fiscal year) within or immediately following the three completed fiscal years identified in the preceding sentence. “Board” means the Board of Directors of the Company. “Compensation Committee” means the Company’s committee of independent directors responsible for executive compensation decisions, or in the absence of such a committee, a majority of the independent directors serving on the Board. “Covered Person” means any person who is, or was at any time, during the Applicable Period, an Executive Officer of the Company. For the avoidance of doubt, a Covered Person may include a former Executive Officer that left the Company, retired, or transitioned to an employee role (including after serving as an Executive Officer in an interim capacity) during the Applicable Period. "Effective Date" means October 2, 2023. “Executive Officer” means the Company’s president, principal executive officer, principal financial officer, principal accounting officer (or if there is no such accounting officer, the controller), any vice-president in charge of a principal business unit, division, or function (such as sales, administration, or finance), any other officer who performs a policy- making function, or any other person (including an officer of the Company’s parent(s) or subsidiaries) who performs similar policy-making functions for the Company. “Financial Reporting Measure” means a measure that is determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any measure that is derived wholly or in part from such measure (including but not limited to, “non-GAAP” financial measures, such as those appearing in the Company’s earnings releases or Management Discussion and Analysis). Stock price and total shareholder return (and any measures derived wholly or in part therefrom) shall be considered Financial Reporting Measures. “Recovery Exception:” A recovery of Recoverable Incentive Compensation shall be subject to a “Recovery Exception” if the Compensation Committee determines in good faith that: (i) pursuing such recovery would violate home country law of the jurisdiction of incorporation of the Company where that law was adopted prior to November 28, 2022 and the Company provides an opinion of home country counsel to that effect acceptable to the Company’s applicable listing exchange; (ii) the direct expense paid to a third party to assist in enforcing this Policy would exceed the Recoverable Incentive Compensation and the Company has (A) made a reasonable attempt to recover such amounts and (B) provided documentation of such attempts to recover to the Company’s applicable listing exchange; or (iii) recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of Section 401(a)(13) or Section 411(a) of the Internal Revenue Code of 1986, as amended, and regulations thereunder. “Incentive Compensation” means any compensation that is granted, earned, or vested based wholly or in part upon the attainment of a Financial Reporting Measure. Incentive Compensation does not include any base salaries (except with respect to any salary increases earned wholly or in part based on the attainment of a Financial Reporting Measure performance goal); bonuses paid solely at the discretion of the Compensation Committee or Board that are not paid from a “bonus pool” that is determined by satisfying a Financial Reporting Measure performance goal; bonuses paid solely upon satisfying one or more subjective standards and/or completion of a specified employment period; non-equity incentive plan awards earned solely upon satisfying one or more strategic measures or operational measures; and equity awards that vest solely based on the passage of time and/or attaining one or more non-Financial Reporting Measures. Incentive Compensation includes any Incentive Compensation Received on or after October 2, 2023 pursuant to a preexisting contract or arrangement. “Received:” Incentive Compensation is deemed “Received” in the Company’s fiscal period during which the Financial Reporting Measure specified in the Incentive Compensation award is attained, even if the payment or grant of the Incentive Compensation occurs after the end of that period. “Recoverable Incentive Compensation” means the amount of any Incentive Compensation (calculated on a pre-tax basis) Received by a Covered Person during the Applicable Period that is in excess of the amount that otherwise would have been Received if the calculation were based on the Restatement. For Incentive Compensation based on (or derived from) stock price or total shareholder return where the amount of Recoverable Incentive Compensation is not subject to mathematical recalculation directly from the information in the applicable Restatement, the amount will be determined by the Compensation Committee based on a reasonable estimate of the effect of the Restatement on the stock price or total shareholder return upon which the Incentive Compensation was Received (in which case, the Company will maintain documentation of such determination of that reasonable estimate and provide such documentation to the Company’s applicable listing exchange). “Restatement” means an accounting restatement of any of the Company’s financial statements filed with the Securities and Exchange Commission under the Exchange Act, or the Securities Act of 1933, as amended, due to the Company’s material noncompliance with any financial reporting requirement under U.S. securities laws, regardless of whether the Company or Covered Person misconduct was the cause for such restatement. “Restatement” includes any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements (commonly referred to as “Big R” restatements), or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period (commonly referred to as “little r” restatements).
