Positive
- IP Australia Notice of Acceptance for patent covering Reqorsa plus PD-L1 antibodies
- Existing granted patents for the combination in U.S. and Korea
- Acclaim-3 trial expansion with a new site at University of Kentucky
Negative
- None.

|---|---|---|---|---|
| Jan 07 | Diabetes program update | Positive | +0.0% | Clinical and regulatory planning update for GPX-002 diabetes gene therapy program. |
| Jan 06 | Preclinical data | Positive | +5.0% | Positive preclinical proof-of-concept data for GPX-002 in Type 2 diabetes models. |
| Nov 24 | Clinical data publication | Positive | -6.7% | Publication of Acclaim-1 Phase 1 REQORSA data showing safety and early efficacy signals. |
| Nov 19 | Trial site expansion | Positive | -9.5% | Added new clinical site for Acclaim-1 and Acclaim-3 Fast Track lung cancer trials. |
| Nov 18 | Patent grant | Positive | -8.7% | USPTO patent for REQORSA with PD-L1 antibodies, covering Acclaim-3 and key markets. |
Recent positive clinical and IP updates have often seen flat or negative next-day moves, suggesting a tendency for the stock to underreact or sell off on favorable news.
Over the last several months, Genprex has highlighted progress across oncology and diabetes programs. In November 2025, Acclaim-1 Phase 1 data and new Acclaim trial sites in lung cancer coincided with negative price reactions despite supportive clinical and regulatory designations. A U.S. patent for REQORSA with PD-L1 antibodies also saw a selloff. In January 2026, encouraging GPX-002 preclinical updates and an upcoming FDA meeting produced flat to modestly positive moves. Today’s Australian patent progress and added Acclaim-3 site fit this ongoing IP and trial-expansion trajectory.
Market Pulse Summary
This announcement highlights IP Australia’s intent to grant a patent for REQORSA in combination with PD-L1 antibodies and the opening of another Acclaim-3 trial site. It follows earlier U.S. and Korean patent protections and prior expansions of Acclaim trial infrastructure. The news underscores Genprex’s emphasis on global intellectual property and trial enrollment. Investors may watch for subsequent patent grants, pace of site additions, and forthcoming clinical readouts to gauge how this strategy supports long-term development of its lung cancer programs.

About Acclaim-3
Acclaim-3 is a Phase 1/2 clinical trial evaluating the combination of REQORSA and Genentech's Tecentriq® (atezolizumab) as maintenance therapy in patients with extensive stage small cell lung cancer (ES-SCLC) who are candidates for maintenance therapy after receiving Tecentriq and chemotherapy as standard of care initial treatment. In this study, patients will be treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced.
The Phase 2 expansion study follows the successful completion of the Phase 1 dose escalation portion of the study, which showed REQORSA was generally well tolerated. There were no dose limiting toxicities, and in Acclaim-3, the Phase 2 patients are receiving the same dose of REQORSA as patients in the Phase 2 portion of Acclaim-1.
The Phase 2 expansion portion is expected to enroll approximately 50 patients. The primary endpoint of the Phase 2 portion is to determine the 18-week progression-free survival rate from the time of the start of maintenance therapy with REQORSA and Tecentriq in patients with ES-SCLC. Patients will also be followed for survival. Genprex's team plans to conduct an interim analysis after the 25th patient enrolled and treated reaches 18 weeks of follow up. The Company expects to complete enrollment of the first 25 patients for interim analysis in the Phase 2 expansion portion of the study in the first half of 2026 and expects the interim analysis in the second half of 2026. The Acclaim-3 clinical trial is supported by FDA Fast Track Designation and Orphan Drug Designation.
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 systemic, non-viral Oncoprex® Delivery System which encapsulates the gene-expressing plasmids using lipid-based nanoparticles in a lipoplex form. 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® Gene Therapy (quaratusugene ozeplasmid), is being evaluated in two clinical trials as a treatment for NSCLC and SCLC. Each of Genprex's lung cancer clinical programs has received a Fast Track Designation from the FDA for the treatment of that patient population, and Genprex's SCLC program has received an FDA Orphan Drug Designation. Genprex's diabetes gene therapy approach is comprised of a novel infusion process that uses an 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 may be distinct enough from beta cells to evade the body's immune system. In a similar approach for Type 2 diabetes, where autoimmunity is not at play, GPX-002 is believed to rejuvenate and replenish exhausted beta cells.
