Genprex Expands Manufacturing Program with Aldevron to Advance Oncoprex™ Clinical Development

June 16, 2020 Off By BusinessWire

Expansion enables full commercial scale plasmid DNA manufacturing capabilities

Manufacturing program supports upcoming clinical trials, including Oncoprex in combination with Tagrisso®, which received FDA Fast Track Designation

AUSTIN, Texas–(BUSINESS WIRE)–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, announced today that it has expanded its program for the manufacture of TUSC2 (Tumor Suppressor Candidate 2) plasmid DNA for its lead drug candidate, Oncoprex™ immunogene therapy, by entering into a new agreement with manufacturing partner Aldevron, LLC, (“Aldevron”). The new agreement provides for production of TUSC2 plasmid DNA, the active agent in Oncoprex, at full commercial scale. The Company’s manufacturing at this scale should also result in significantly lower costs per unit of product manufactured due to economies of scale.

Genprex’s upcoming clinical trials include a Phase I/II trial of Oncoprex combined with osimertinib (marketed by AstraZeneca as Tagrisso®) for non-small cell lung cancer (NSCLC), which received Fast Track Designation in January 2020 and is expected to be initiated in early 2021. A clinical trial of Oncoprex in combination with pembrolizumab (marketed by Merck as Keytruda®) in NSCLC is also planned.

“We are pleased with continued progress in the scale-up of our manufacturing processes. This new agreement with Aldevron increases our manufacturing capabilities in support of our clinical trials utilizing Oncoprex immunogene therapy in combination with targeted therapies and immunotherapies against lung cancer,” said Rodney Varner, Chairman and Chief Executive Officer of Genprex.

“Our team is excited about the expansion of our manufacturing agreement and elevation of our long-standing relationship with Genprex,” said Michelle Berg, President of GMP Nucleic Acids at Aldevron. “Aldevron’s GMP facility and campus buildout ensures we can meet the future manufacturing demands of companies experiencing significant growth such as Genprex; thereby enabling our ultimate goal of impacting the lives of patients.”

Oncoprex consists of TUSC2 plasmid DNA encapsulated in a lipid nanoparticle. The TUSC2 gene is the active agent in Oncoprex. Data indicate that the resultant product when transfected into cancer cells both induces cell signaling that triggers programmed cell death and modulates the immune system so that the cancer cells are more susceptible to treatment.

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, Oncoprex™, is being evaluated as a treatment for non-small cell lung cancer (NSCLC). Oncoprex 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. Oncoprex 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 Oncoprex immunogene therapy for NSCLC in combination therapy with osimertinib (AstraZeneca’s Tagrisso®) for patients with EFGR mutations whose tumors progressed after treatment with osimertinib alone.
