Genprex's research collaborators presented positive preclinical data on the company's diabetes gene therapy drug candidate at the 2026 American Society of Gene and Cell Therapy Annual Meeting. The collaborators presented preclinical data demonstrating that the diabetes gene therapy can reverse hyperglycemia in Type 2 diabetic mouse models. At two and/or four weeks after surgery, researchers performed intraperitoneal glucose tolerance testing or IPGTT, insulin tolerance testing or ITT, glucose-stimulated insulin secretion or GSIS, calculated HOMA-IR and assessed glucagon secretion. The results at four weeks showed major improvements in the control of diabetes. At four weeks after surgery, ex-vivo glucose-stimulated insulin secretion showed that islets isolated from HFD+CMV-PM-GFP treated mice had insulin secretion similar to islets from RD mice, and both groups had increased insulin secretion compared to islets from the control HFD groups, indicating improved beta-cell function with PM treatment. PM gene therapy reverses hyperglycemia, likely in large part by specifically enhancing beta-cell function and maturation. This approach is technically translatable to humans using endoscopic retrograde cholangiopancreatography to deliver PM gene therapy to the pancreas.

About GNPX
Genprex, Inc. is a clinical-stage gene therapy company focused on developing therapies for patients with cancer and diabetes. The Company's technologies are designed to administer disease-fighting genes to provide new therapies for large patient populations with cancer and diabetes, who have limited treatment options. Its oncology program 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. Its oncology drug candidate, Reqorsa Gene Therapy (quaratusugene ozeplasmid), is developed in combination with approved cancer drugs to treat Non-Small Cell Lung Cancer (NSCLC) and Small Cell Lung Cancer (SCLC). GPX-002 is being developed by the Company 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.

Genprex Partners with UT MD Anderson to Research Lung Cancer Biomarkers
- Research Agreement Signed: Genprex has entered into a new Sponsored Research Agreement with The University of Texas MD Anderson Cancer Center to study biomarkers that may predict patient response to Reqorsa gene therapy, demonstrating the company's commitment to personalized cancer treatment.
- Biomarker Discovery: Researchers have identified TROP2 and PTEN as potential biomarkers in preclinical studies, which may increase the likelihood of patient response to Reqorsa, thereby optimizing patient selection strategies for clinical trials.
- Clinical Trial Progress: The Acclaim-1 and Acclaim-3 clinical trials are currently underway, with the former combining Reqorsa with AstraZeneca's Tagrisso and the latter with Genentech's Tecentriq, both showing good tolerability and early signs of efficacy.
- Long-term Treatment Effects: In the Acclaim-1 trial, one patient experienced over 42 months of progression-free survival following Reqorsa treatment, indicating that this therapeutic approach may offer significant long-term benefits for certain patients.
