Strengthens Patent Estate and Expands Protection in Another Target Market

AUSTIN, Texas, April 30, 2026 /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 The Israel Patent Office (ILPO) has granted Genprex a patent covering the use of Reqorsa® Gene Therapy (quaratusugene ozeplasmid) in combination with PD-1 antibodies for the treatment of cancer.

This patent will expand on the previously granted patents for REQORSA in combination with PD-1 antibodies, which have been granted in the U.S., Japan, Mexico, Russia, Australia, Chile, China, Singapore and Europe.

REQORSA is initially being developed in combination with prominent, approved cancer drugs to treat lung cancer. In preclinical studies, REQORSA has been shown to be complementary with targeted drugs and immunotherapies. The Company believes REQORSA's unique attributes position it to provide potential treatments that improve on these current therapies for patients with lung cancer and possibly other cancers.
