Provides Additional Protection in Large Markets for Therapeutic Combination in Acclaim-2 Phase 1/2 Clinical Trial
Patent Already Granted for Same Combination in
"This is a very important patent because it provides Genprex with additional protection for our REQORSA gene therapy in combination with PD1 antibodies, such as Keyruda®, which is the subject of our ongoing Acclaim-2 clinical trial for the treatment of lung cancer," said Thomas Gallagher, Esq., Senior Vice President of Intellectual Property and Licensing at Genprex. "Genprex has already received this patent protection in the
Acclaim-2 is an open-label, dose escalation and clinical response study of REQORSA in combination with Keytruda in patients with advanced, metastatic non-small cell lung cancer (NSCLC) whose disease progressed after treatment with Keytruda.

About Acclaim-2
The Acclaim-2 trial is a Phase 1/2 open-label, dose-escalation and clinical response study of REQORSA in combination with Keytruda in patients with advanced, metastatic non-small-cell lung cancer who have progressed after treatment with Keytruda. The Company anticipates enrolling patients at approximately 10 clinical sites and estimates that the Phase 1 dose escalation portion of the Acclaim-2 trial will enroll up to 18 patients, the Phase 2 expansion portion will enroll approximately 36 patients, and the Phase 2 randomized portion will enroll approximately 126 patients. Patients enrolled in the Phase 2 randomized portion of the study will be randomized 2:1 to either REQORSA and Keytruda combination therapy or to chemotherapy (docetaxel with or without ramucirumab). Patients will be treated until disease progression or unacceptable toxicity is experienced. Patients must have histologically confirmed unresectable stage III or IV NSCLC (any histology) with radiological progression on Keytruda and an ECOG performance status of 0 to 1. Genprex expects to complete enrollment for the Phase 1 dose escalation portion of Acclaim-2 by the first quarter of 2024.
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). Each of Genprex's three lung cancer clinical programs have 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.
