National Institutes of Health (NIH) Awards Research Grant of $2.59 Million to University of Pittsburgh for Diabetes Gene Therapy Technology Licensed by Genprex

Grant to fund ongoing preclinical research for important proof-of-principle non-human studies in preparation for human gene therapy clinical trials

AUSTIN, Texas--()--Genprex, Inc. (“Genprex” or the “Company”) (NASDAQ: GNPX), a clinical-stage gene therapy company developing potentially life-changing technologies for patients with cancer and diabetes, today announced that Dr. George K. Gittes, MD of the University of Pittsburgh, the lead researcher that developed the Company’s potentially curative diabetes gene therapy, was awarded a grant of $2.59 million from the National Institutes of Health (“NIH”) National Institute of Diabetes and Digestive and Kidney Diseases. The grant will assist Dr. Gittes’s development for his research project titled, “Alpha Cell Conversion to Beta Cells in Non-human Primates” and will build upon his accumulating groundbreaking gene therapy work toward finding a cure for diabetes. In this project, Dr. Gittes’ research team will conduct important proof-of-principle studies in non-human primates as the last steps in preparation for human gene therapy clinical trials. This technology is the subject of an exclusive license agreement entered into between Genprex and the University of Pittsburgh in February of 2020.

“We are excited to receive this funding to support our research in diabetic primates as we move toward human clinical trials,” said Dr. George Gittes, Co-Scientific Director and Professor of Surgery at the UPMC (University of Pittsburgh Medical Center) Children’s Hospital of Pittsburgh and the lead researcher behind the diabetes gene therapy. “We saw encouraging data in our preclinical mice studies, where the gene therapy reprogrammed pancreatic cells to restore normal blood glucose levels in diabetic mice for approximately four months, which could translate to decades in humans. More recently, preliminary results in non-human primates (monkeys) has also been very promising.”

Dr. Gittes’ gene therapy for diabetes, which Genprex refers to as “GPX-002,” uses a novel infusion process comprised of an endoscope and an adeno-associated virus (AAV) vector to deliver Pdx1 and MafA genes to the pancreas. The genes express proteins that transform alpha cells in the pancreas into functional beta-like cells, which can produce insulin but are distinct enough from beta cells to evade the body’s immune system.

Diabetes affects approximately 10 percent of the U.S. population, or more than 34 million people. The diabetes gene therapy could not only become a new treatment option for millions of diabetes patients who need insulin replacement therapy, but it holds the potential to provide long-term effectiveness, or may even be a cure, for diabetic patients.

Dr. Gittes is the inventor of the gene therapy for diabetes, and he is eligible to receive royalties on this technology in the future.

About Genprex, Inc.

Genprex, Inc. is a clinical-stage gene therapy company developing potentially life-changing technologies for patients with cancer and diabetes. Genprex’s technologies are designed to administer disease-fighting genes to provide new treatment options for large patient populations with cancer and diabetes who currently have limited treatment options. Genprex works with world-class institutions and collaborators to in-license and develop drug candidates to further its pipeline of gene therapies in order to provide novel treatment approaches. The Company’s lead product candidate, GPX-001 (quaratusugene ozeplasmid), is being evaluated as a treatment for non-small cell lung cancer (NSCLC). GPX-001 has a multimodal mechanism of action that has been shown to interrupt cell signaling pathways that cause replication and proliferation of cancer cells; re-establish pathways for apoptosis, or programmed cell death, in cancer cells; and modulate the immune response against cancer cells. GPX-001 has also been shown to block mechanisms that create drug resistance. In January 2020, the U.S. Food and Drug Administration granted Fast Track Designation for GPX-001 for NSCLC in combination therapy with osimertinib (AstraZeneca’s Tagrisso®) for patients with EFGR mutations whose tumors progressed after treatment with osimertinib alone.
