Preclinical Data Presented at the 2024 EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics
AUSTIN, Texas , Oct. 28, 2024 /PRNewswire/ -- Genprex, Inc. ("Genprex" or the "Company") (NASDAQ: GNPX), a clinical-stage gene therapy company focused on developing life-changing therapies for patients with cancer and diabetes, today announced that research collaborators delivered poster presentations at the 2024 EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics held October 23-25, 2024 in Barcelona, Spain. The collaborators presented posters on positive preclinical data from studies of Genprex's lead drug candidate, Reqorsa® Gene Therapy (quaratusugene ozeplasmid), for the treatment of Ras inhibitor resistant lung cancer, mesothelioma and glioblastoma.
"We are pleased by this promising preclinical data, presented before a prestigious audience of oncology researchers, of REQORSA's potential in serious and difficult to treat cancers including KRAS G12C mutant lung cancer, mesothelioma, and glioblastoma," said Ryan Confer, President and Chief Executive Officer at Genprex. "The role of TUSC2 in lung cancer has been well established, and TUSC2 restoration is being evaluated clinically. However, we are highly encouraged by our preclinical programs expanding the potential use of REQORSA to treat a variety of cancer indications, where patient populations have unmet medical needs."
Genprex has filed two provisional patent applications based on data from two of the presentations. One application involves using REQORSA to treat mesothelioma and the other uses REQORSA to treat glioblastoma. Genprex is a co-owner of the applications along with the respective institutions. TUSC2 is the tumor suppressor gene used in REQORSA. Last month, Genprex announced the formation of its Mesothelioma Clinical Advisory Board to support the Company's preclinical mesothelioma oncology program. The Board is comprised of four world-renown researchers from major research institutions specializing in the treatment of mesothelioma.

About Reqorsa® Gene Therapy
REQORSA (quaratusugene ozeplasmid) consists of a plasmid containing the TUSC2 gene encapsulated in non-viral lipid-based nanoparticles in a lipoplex form (the Company's Oncoprex® Delivery System), which has a positive charge. REQORSA is injected intravenously and specifically targets cancer cells. REQORSA is designed to deliver the functioning TUSC2 gene to negatively charged cancer cells while minimizing uptake by normal tissue. Laboratory studies conducted at MD Anderson show that the uptake of TUSC2 in tumor cells in vitro after REQORSA treatment was 10 to 33 times the uptake in normal cells.
About Genprex, Inc.
Genprex, Inc. is a clinical-stage gene therapy company focused on developing life-changing therapies for patients with cancer and diabetes. Genprex's technologies are designed to administer disease-fighting genes to provide new therapies for large patient populations with cancer and diabetes who currently have limited treatment options. Genprex works with world-class institutions and collaborators to develop drug candidates to further its pipeline of gene therapies in order to provide novel treatment approaches. Genprex's oncology program utilizes its systemic, non-viral Oncoprex® Delivery System which encapsulates the gene-expressing plasmids using lipid-based nanoparticles in a lipoplex form. The resultant product is administered intravenously, where it is taken up by tumor cells that then express tumor suppressor proteins that were deficient in the tumor. The Company's lead product candidate, Reqorsa® Gene Therapy (quaratusugene ozeplasmid), is being evaluated in two clinical trials as a treatment for NSCLC and SCLC. Each of Genprex's lung cancer clinical programs has received a Fast Track Designation from the FDA for the treatment of that patient population, and Genprex's SCLC program has received an FDA Orphan Drug Designation. Genprex's diabetes gene therapy approach is comprised of a novel infusion process that uses an AAV vector to deliver Pdx1 and MafA genes directly to the pancreas. In models of Type 1 diabetes, GPX-002 transforms 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 a similar approach, GPX-002 for Type 2 diabetes, where autoimmunity is not at play, is believed to rejuvenate and replenish exhausted beta cells.
