Genprex (NASDAQ: GNPX) details GPX-002 diabetes gene therapy progress

Rhea-AI Filing Summary

Genprex, Inc. filed an 8-K describing new investor presentation materials and important updates on its GPX-002 diabetes gene therapy program. The company furnished an investor deck that may be used in meetings with investors and analysts and made available on its website.

Genprex reported 2025 milestones for GPX-002, including starting preclinical research in Type 2 diabetes animal models, transferring production of GPX-002 to an experienced contract development and manufacturing organization, and submitting a request to the FDA for a meeting on its Investigational New Drug–enabling studies, described as a pivotal step toward human clinical trials. GPX-002 is being developed for both Type 1 and Type 2 diabetes, with preclinical mouse and non-human primate data showing restored or improved blood glucose control, reduced insulin requirements, higher c‑peptide levels, and improved glucose tolerance.

Insights

Biotech and clinical development analyst

Genprex advances GPX-002 toward IND-enabling discussions and scales manufacturing, but remains in preclinical stages.

The update highlights that Genprex has progressed its diabetes gene therapy candidate GPX-002 by initiating preclinical research in Type 2 diabetes animal models and moving manufacturing to an experienced CDMO. It has also requested a meeting with the FDA regarding IND-enabling studies, which is framed as a pivotal step on the path to human clinical trials.

The program targets both Type 1 and Type 2 diabetes. In Type 1 models, GPX-002 is designed to convert pancreatic alpha cells into insulin-producing beta-like cells and has shown extended normalization of blood glucose and reduced insulin needs with improved c‑peptide and glucose tolerance in non-human primate studies. In Type 2 models, the therapy aims to rejuvenate exhausted beta cells and has shown activity in both mouse and primate studies.

The disclosed information underscores scientific momentum but also includes extensive forward-looking statement cautions, emphasizing risks around clinical development timelines, regulatory outcomes, manufacturing scale-up, liquidity, and Nasdaq listing compliance. Overall, this represents incremental pipeline progress rather than a definitive value inflection, with future impact dependent on FDA feedback and eventual clinical trial results.

Item 8.01 Other Events.

On January 7, 2026, Genprex issued a press release announcing clinical program updates on its diabetes gene therapy program for GPX-002, the Company’s diabetes gene therapy drug candidate, detailing recent achievements and future advancements, including the initiation of the Company’s preclinical research in Type 2 diabetic (“T2D”) animal models, the execution of the Company’s strategic plan to transfer production of GPX-002 to an experienced contract development and manufacturing organization (“CDMO”), and the submission of a request to the FDA for a meeting regarding the Company’s Investigational New Drug (“IND”)-enabling studies, marking a pivotal step toward human clinical trials.

The press release noted that Genprex has achieved important milestones within its diabetes program in 2025, marking progress in its clinical drug development. These include:

● Expansion of Research: Genprex commenced preclinical studies in T2D animal models, broadening the scope of its investigational studies beyond Type 1 diabetes (“T1D”). This step allows for an augmented, comprehensive evaluation of GPX-002's effects in relevant disease models. Moreover, preliminary preclinical data demonstrated in vivo proof-of-concept for the novel diabetes gene therapy in T2D animal studies, where GPX-002 rejuvenated exhausted beta cells and normalized glucose levels.

● Regulatory Engagement: Genprex has executed its strategy to submit a meeting request to the U.S. Food and Drug Administration (“FDA”) by the end of 2025. This meeting, which is scheduled to occur in the first quarter of 2026, is intended to discuss the necessary IND-enabling preclinical studies, a critical step before potentially initiating clinical trials in humans.

● Technology Transfer: Genprex has successfully transferred the manufacturing process for the production of GPX-002 from the Company’s academic collaborators where it was previously manufactured, to the Company’s experienced, integrated network of CDMOs and other vendors.

The press release further stated that the Company is preparing for necessary next steps to advance GPX-002, including:

● Manufacturing Scale Up: The Company plans to begin the clinical scale production of GPX-002 in a current Good Manufacturing Practices (“cGMP”) compliant facility, allowing Genprex to accelerate its manufacturing processes necessary for IND-enabling preclinical studies and clinical trials.

● Product Optimization: Genprex is continuing work with CDMOs and research partners to optimize constructs and evaluate an alternative second-generation approach for GPX-002 using a non-viral lipid nanoparticle delivery system.

● Toxicology Studies: Following the FDA interaction, Genprex will finalize the design and initiate toxicology studies. Subsequent data from the toxicology studies are expected to enable IND filing. Toxicology studies are a required step of drug development, ensuring that new treatments are safe and effective for human use while identifying potential risks, determining safe dosages and monitoring for side effects. 

GPX-002 is under development as a potential treatment for both T1D and T2D. In T1D, GPX-002 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 vivo, preclinical studies show that GPX-002 restored normal blood glucose levels for an extended period of time in T1D mouse models. In T1D non-human primate (“NHP”) in vivo models, GPX-002 demonstrated the ability to decrease insulin requirements, increase c-peptide levels and improve glucose tolerance.

In a similar approach for T2D, where autoimmunity is not at play, GPX-002 demonstrated the ability to replenish and rejuvenate exhausted beta cells that make insulin in both mouse and NHP models.
