Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1 - Description of Business and Basis of Presentation Unless the context requires otherwise, references to “Genprex,” or the “Company,” in this Quarterly Report on Form 10-Q refer to Genprex, Inc. Genprex, 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® gene 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 multimodal effects on cancer cells. It harms the metabolism of cancer cells, which leads to reduced cancer cell growth. It has a mechanism of action whereby it decreases tumor glucose metabolism, 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 increases the immune response against cancer cells. In preclinical studies, REQORSA has been shown to be complementary with targeted drugs and immunotherapies. The Company’s strategy is to develop REQORSA in combination with currently 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. The TUSC2 gene, which is the key component of REQORSA and plays a vital role in cancer suppression and normal cell metabolism, 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”). The Company believes that its ONCOPREX Delivery System allows for the delivery of a number of cancer-fighting tumor suppressor 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, the Company entered into a sponsored research agreement with MD Anderson to support further preclinical studies of TUSC2 and other tumor suppressor genes. Additionally, the Company is collaborating with MD Anderson to discover, develop and utilize biomarkers to select the patient population most likely to respond to REQORSA and enable decisions on progression of its drug candidates to the next phase of development. MD Anderson researchers currently are analyzing biomarkers that may indicate a strong positive or negative response to REQORSA in lung cancer that could be used to enrich the Company’s population of responders in its clinical trials. Acclaim – 1: The Company currently is 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® (osimertinib) in patients with late-stage NSCLC that has activating epidermal growth factor receptor (“EGFR”) mutations and progression on treatment with Tagrisso or Tagrisso-containing regimens. 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 the recommended Phase 2 dose (“RP2D”) of REQORSA to 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® (erlotinib) for the treatment of late-stage lung cancer. There were three patients out of the twelve originally enrolled in the Phase 1 dose escalation portion of the study who had prolonged progression-free survival (“PFS”). One patient attained a partial remission after the second course of REQORSA and Tagrisso and has maintained this response through 56 courses of treatment (approximately 39 months) and continues to receive REQORSA and Tagrisso treatment to date. A second patient had stable disease without disease progression through 32 courses of treatment (approximately 24 months) but then had disease progression and REQORSA treatment was stopped. A third patient had stable disease without disease progression through 14 courses of treatment (approximately 10 months) before disease progression and is no longer receiving treatment. Genprex opened the Phase 2a expansion portion of the study and enrolled and dosed the first patient in January 2024. The initial trial design of the Phase 2a expansion portion of the study included two cohorts with half being patients who received only prior Tagrisso treatment and the other half being patients who received prior Tagrisso treatment and chemotherapy. However, as previously announced in August 2024, based on resource prioritization and to focus on the patients for whom REQORSA is most likely to show a benefit, the Company decided to limit its enrollment efforts moving forward to patients who received only prior Tagrisso treatment and cease enrollment of the second cohort (patients who received prior Tagrisso treatment and chemotherapy). However, noting that two of the patients with prolonged PFS in the Phase 1 portion of the study had previously received both chemotherapy and Tagrisso, in February 2025, the Company amended the protocol to allow entry of patients progressing on Tagrisso or Tagrisso-containing regimens. The Phase 2a expansion portion of the trial is now expected to enroll approximately 33 patients; all of whom have progressed on Tagrisso or Tagrisso-containing regimens. The Phase 2b randomized portion of the study, in which patients progressing on prior Tagrisso treatment will be randomized 1:1 to either REQORSA and Tagrisso combination therapy or to platinum-based chemotherapy, remains unchanged. There will be an interim analysis following the treatment of 19 patients in the Phase 2a portion of the Acclaim-1 study. The Company expects to complete the enrollment of the first 19 patients for interim analysis in the Phase 2a expansion portion of the study in the first half of 2026 and expects the interim analysis in the second half of 2026. 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 on Tagrisso treatment. The Phase 2a expansion portion of the Acclaim-1 study provides the Company the advantage of early insight into drug effectiveness in defined and distinct patient populations at the maximum tolerated dose 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 the study. Acclaim – 2: The Acclaim-2 trial involved a combination of REQORSA and Merck & Co.’s Keytruda® (pembrolizumab) in patients with late-stage NSCLC whose disease has progressed after treatment with Keytruda. As previously announced in August 2024, based on a number of factors, including enrollment challenges and delays due to competition for investigators and eligible patients with numerous other trials involving the same patient population, the Company decided to cease enrollment of new patients in the Acclaim-2 trial to prioritize its resources and focus on the other two Acclaim trials in SCLC and NSCLC, respectively. There are no longer any patients receiving study treatment in the Acclaim-2 trial. Although the Acclaim-2 study in patients progressing on Keytruda containing regimens has been closed due to, among other factors, slow enrollment, the Company continues to believe that this combination could be beneficial. Acclaim – 3: The Company is currently enrolling and treating patients in the Phase 2 expansion 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® (atezolizumab) as maintenance therapy for 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. On December 16, 2024, the Company announced that it had completed the Phase 1 dose escalation portion of the Acclaim-3 clinical trial. Based on full safety data, which showed no DLTs, the Acclaim-3 Safety Review Committee determined that the RP2D of REQORSA will be 0.12 mg/kg, which was the highest dose level delivered in the Phase 1 portion of the trial, and approved the opening of the Phase 2 expansion portion of the trial. The Company anticipates that the Phase 2 expansion portion will enroll approximately 50 patients at approximately 10 to 15 U.S sites. Patients will be treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. 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. A Phase 2 futility analysis will be performed after the 25th patient enrolled and treated reaches 18 weeks of follow up. The Company expects to complete enrollment of the first 25 patients for interim analysis in the Phase 2 expansion portion of the study in the first half of 2026 and expects the interim analysis in the second half of 2026. The Acclaim-3 clinical trial has received FDA Fast Track Designation for this patient population and Acclaim-3 has also received an FDA Orphan Drug Designation. Diabetes Gene Therapy In diabetes, Genprex has exclusively licensed from the University of Pittsburgh of the Commonwealth System of Higher Education (“University of Pittsburgh” or “UP”) 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 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. The Company 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, Genprex decided to continue with its planned additional nonclinical studies before requesting regulatory guidance for the IND-enabling studies. The Company is currently working with the University of Pittsburgh on species analyses for the animal models as well as on other regulatory and clinical strategic planning, including the planned initiation of research in Type 2 diabetes animal models, following which the Company plans to submit a request to the FDA to meet regarding IND-enabling studies by the end of 2025. In May 2025, following the recent completion of our August 2022 sponsored research agreement with UP, Genprex entered into a new sponsored research agreement with UP to study Type 1 diabetes and Type 2 diabetes in animal models. The new sponsored research agreement also includes a revised research plan to encompass the Company’s most recent technologies to which Genprex originally acquired exclusive rights from UP in July 2023 as amended and restated in the comprehensive New UP License Agreement in February 2025 (as defined and described below). 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. On February 17, 2025, Genprex and the University of Pittsburgh entered into an amended and restated Exclusive License Agreement (the “New UP License Agreement”), which updated and consolidated into a single agreement the Company’s prior license agreements with UP. Pursuant to the New UP License Agreement, UP granted to Genprex a worldwide, exclusive license for certain patents and related technology, collectively referred to as the “Licensed Technology,” and a worldwide, non-exclusive license to use certain related know-how. The Licensed Technology covered by the New UP License Agreement is based on the same general gene therapy approach as covered under the Company’s prior license agreements with UP (less the previously-licensed macrophage technology), whereby an adeno-associated virus vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. More specifically, the Licensed Technology covered by the New UP License Agreement is related to a gene therapy for both Type 1 diabetes and Type 2 diabetes using the genes of the Pdx1 and MafA transcription factors controlled by insulin, glucagon and MafB promoters. In February 2023, the Company’s research collaborators at UP presented preclinical data in a non-human primate 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. In June 2025, the Company’s collaboration partners had two presentations at the 2025 American Diabetes Association (“ADA”) 85th Scientific Sessions. Genprex’s research collaborators from UP were invited to give an oral presentation highlighting their work in non-human primate models of Type 1 diabetes. In addition, Genprex’s contract development and manufacturing organization collaborators presented a poster on a non-viral lipid nanoparticle delivery system that would allow a patient to receive multiple treatments. Formation of Wholly Owned Subsidiary On February 18, 2025, Genprex announced the formation of a wholly-owned subsidiary, Convergen Biotech, Inc. (“Convergen”). The Company intends to transfer the diabetes program into Convergen in an effort to focus development and commercialization efforts separately from the Company's oncology program. Capital Requirements, Liquidity and Going Concern Considerations The Company’s unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) applicable to a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. However, 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 unaudited condensed consolidated 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 March 2026. 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 and is evaluating various strategies to obtain additional financing, although the Company can give no assurance that its plans or strategies will be effectively implemented in such a way that they will sufficiently alleviate or mitigate the conditions and events noted above. 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 unaudited condensed consolidated financial statements do not include any adjustments that might be necessary if Genprex is unable to continue as a going concern.
