Genprex Collaborators Present Positive Preclinical Research on Diabetes Gene Therapy at the 2025 American Diabetes Association 85th Scientific Sessions

Core Viewpoint - Genprex, Inc. has presented promising preclinical research on its diabetes gene therapy candidate GPX-002, demonstrating its potential to improve glucose homeostasis by reprogramming alpha cells into beta-like cells, as showcased at the 2025 American Diabetes Association Scientific Session [1][2]. Group 1: Research Findings - The research indicates that alpha cells in animal models of Type 1 diabetes (T1D) can transdifferentiate into beta-like cells after being treated with GPX-002, maintaining improved glucose control for three months [2][6]. - The gene therapy utilizes recombinant adeno-associated virus (rAAV) to deliver Pdx1 and MafA genes directly into the pancreatic duct, effectively converting alpha cells into insulin-secreting beta-like cells without the need for immunosuppression in mouse models [3][12]. - In non-human primate studies, the infusion of rAAV resulted in improved glucose tolerance and reduced insulin requirements one month post-infusion, with ongoing evaluations of immune responses to the therapy [5][8]. Group 2: Clinical Development - Genprex is advancing GPX-002 for both Type 1 and Type 2 diabetes, with the same gene therapy approach applied to both conditions, aiming to rejuvenate exhausted beta cells in Type 2 diabetes [9][12]. - The company is currently conducting preclinical studies to gather additional data on the efficacy of GPX-002 after six months of immunosuppression [8][9]. - The therapy is designed to be administered via a routine endoscopy procedure in humans, enhancing its potential for clinical application [9]. Group 3: Company Overview - Genprex, Inc. is a clinical-stage gene therapy company focused on developing innovative therapies for cancer and diabetes, collaborating with leading institutions to advance its drug candidates [10][11]. - The company’s oncology program includes the Oncoprex® Delivery System, which encapsulates gene-expressing plasmids for intravenous administration, targeting tumor cells [11]. - Genprex aims to provide new treatment options for patients with limited alternatives, leveraging its gene therapy technologies [10].
