The studies used the Company's non-viral ONCOPREX® Nanoparticle Delivery System in KRAS/STK11 mutant anti-PD1 resistant metastatic human non-small cell lung cancer (NSCLC) humanized mouse models. These positive data support the therapeutic potential of the Company's non-viral delivery system, which is being used in its current REQORSA® clinical oncology programs. REQORSA immunogene therapy is the Company's lead drug candidate for lung cancer. The preclinical data also provide further evidence that the ONCOPREX Nanoparticle Delivery System has the ability to be successful using tumor suppressor genes other than the TUSC2 gene that is already in use in clinical trials with REQORSA. Lastly, the data suggest that targeting NSCLC with the NPRL2 gene, potentially in combination with anti-PD1 treatment as well, may provide therapeutic potential for lung cancer patients progressing on anti-PD1 treatment.
"The study utilized the same delivery platform that Genprex uses with our REQORSA product candidate but with a different tumor suppressor gene," said Mark Berger, MD, Chief Medical Officer at Genprex. "The whole point of our oncology program is to identify tumor suppressor genes, which are systematically deleted during cancer development, and then re-express the tumor suppressor genes in cancers. This process has shown preclinically that it can achieve strong efficacy and is currently being evaluated in Phase 1/2 clinical trials of REQORSA. Now researchers have replicated that process in in vitro studies with the NPRL2 gene, which we believe is validation that ONCOPREX as a platform may be used with multiple tumor suppressor genes to address multiple types of cancer."
The abstract entitled, "NPRL2 gene therapy induces effective antitumor immunity in KRAS/STK11 mutant anti-PD1 resistant metastatic human non-small cell lung cancer (NSCLC) in a humanized mouse model," has been made available on Genprex's website here.

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 proprietary, non-viral ONCOPREX® Nanoparticle Delivery System which encapsulates the gene-expressing plasmids using lipid nanoparticles. 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® (quaratusugene ozeplasmid), is being evaluated in three clinical trials as a treatment for non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Both NSCLC clinical programs received a Fast Track Designation from the Food and Drug Administration. Genprex's diabetes gene therapy approach is comprised of a novel infusion process that uses an adeno-associated virus (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 are distinct enough from beta cells to evade the body's immune system. In a similar approach, GPX-003 for Type 2 diabetes, where autoimmunity is not at play, is believed to rejuvenate and replenish exhausted beta cells.
