On May 5, 2020 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, reported that it has entered into a Patent and Technology License Agreement ("License Agreement") with The University of Texas MD Anderson Cancer Center ("MD Anderson") in which MD Anderson granted to Genprex an exclusive worldwide license to a portfolio of 16 patent applications and related technology ("Licensed IP") for the treatment of cancer using Genprex’s lead drug candidate and TUSC2 gene therapy, known as "Oncoprex" or "GEN-001," in combination with immunotherapies (Press release, Genprex, MAY 5, 2020, View Source [SID1234557044]). This is a distinct therapeutic approach from that of combining Oncoprex with targeted therapies such as osimertinib (marketed as Tagrisso by AstraZeneca).

Genprex was recently awarded U.S. FDA Fast Track designation for use of Oncoprex combined with Tagrisso for the treatment of non-small cell lung cancer (NSCLC) patients with EGFR mutations whose tumors progressed after treatment with Tagrisso alone. The Company is now preparing to file an Investigational New Drug application to initiate a clinical trial of Oncoprex in combination with pembrolizumab (marketed as Keytruda by Merck) in NSCLC.
"We are pleased to advance the intellectual property that is covered by this License Agreement," said Rodney Varner, Genprex’s Chairman and Chief Executive Officer. "We are excited to be developing two distinct therapeutic approaches to lung cancer utilizing the combination of our gene therapy with successful targeted therapies, such as Tagrisso, and immunotherapies, such as Keytruda, to potentially improve patient outcomes and increase the number of patients who may benefit from these important therapies."
Immunotherapy or immunotherapy combined with chemotherapy is now the first-line standard of care for the majority of lung cancer patients. Published preclinical data indicate that when Oncoprex is combined with immunotherapies such as Keytruda, Oncoprex is synergistic with those drugs, meaning that the combination is more effective than either drug alone. The combination of Oncoprex and Keytruda may lead to better outcomes for many lung cancer patients.
The Licensed IP covers the use of Oncoprex in combination with one or more immunotherapies, including anti-PD1 antibodies, anti-PDL1 antibodies, anti-PDL2 antibodies, anti-CTLA-4 antibodies and/or anti-KIR antibodies for the treatment of cancer. These immunotherapies include pembrolizumab (Merck’s largest selling drug Keytruda), nivolumab (Bristol-Myers Squibb’s Opdivo), ipilimumab (Bristol-Myers Squibb’s Yervoy), and others. Use of chemotherapy in combination with Oncoprex and immunotherapy is also covered by the Licensed IP. While the initial disease indication for Oncoprex is NSCLC, the Licensed IP claims patent protection for combination use of Oncoprex in all types of cancers.
The License Agreement also provides for payment to MD Anderson of an up-front license fee and annual maintenance fees, with the potential for milestone payments, sublicensing fees, and product royalties.
