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 Secures Patent for Reqorsa Gene Therapy in Cancer Treatment
- Patent Approval: Genprex has received a Notice of Allowance from the Canadian Intellectual Property Office for its Reqorsa gene therapy patent, covering its use in combination with PD-1 or PD-L1 antibodies, which strengthens the company's intellectual property portfolio and enhances its competitive position in the Acclaim-3 clinical trial.
- Clinical Trial Progress: The Acclaim-3 trial is evaluating the combination of Reqorsa and Genentech's Tecentriq® in patients with extensive stage small cell lung cancer, with plans to enroll approximately 50 patients, aiming to determine the 18-week progression-free survival rate, providing critical data for future treatment strategies.
- Market Demand Insight: According to the Canadian Cancer Society, an estimated 32,900 people will be diagnosed with lung cancer in Canada in 2026, making it the leading cause of cancer death, which presents a significant market opportunity for Genprex's therapeutic solutions.
- Strategic Implications: Securing this patent not only solidifies Genprex's intellectual property foundation in cancer treatment but also lays the groundwork for future innovative treatment strategies, further driving the company's expansion in the global market.
