Core Viewpoint - Genprex, Inc. announced the publication of positive preclinical data on its lead drug candidate, Reqorsa® Gene Therapy, for treating KRASG12C mutant non-small cell lung cancer (NSCLC) [1][2][3] Group 1: Research and Development - The abstract detailing the preclinical data was published in the online Proceedings supplement of Cancer Research [1] - The data will be presented at the 2025 AACR Annual Meeting, highlighting advances in cancer treatment [2][3] - The study demonstrated that TUSC2 gene therapy (REQORSA) effectively overcomes acquired resistance to sotorasib in KRASG12C mutant NSCLC mouse xenografts [4][5][6] Group 2: Mechanism and Efficacy - Acquired resistance to Lumakras® (sotorasib) presents a significant challenge in treating KRASG12C mutant NSCLC, necessitating alternative strategies [4] - TUSC2 gene therapy exhibits multifunctional activity, inhibiting downstream signaling pathways, inducing tumor cell death, and activating immune responses [4][5] - REQORSA alone showed significant antitumor efficacy, and a synergistic effect was observed when combined with sotorasib [5][6] Group 3: Product Information - Reqorsa® Gene Therapy consists of a plasmid containing the TUSC2 gene encapsulated in non-viral lipid-based nanoparticles [7] - The therapy is designed to specifically target cancer cells while minimizing uptake by normal tissue, with laboratory studies showing 10 to 33 times greater uptake in tumor cells compared to normal cells [8] Group 4: Company Overview - Genprex, Inc. is focused on developing gene therapies for cancer and diabetes, utilizing its Oncoprex® Delivery System [9] - The company’s lead product candidate, Reqorsa, is currently being evaluated in clinical trials for NSCLC and small cell lung cancer (SCLC) [9]
