Genprex Inc. (NASDAQ: GNPX) announced that its collaborators presented positive preclinical data across three studies for its lead drug candidate, Reqorsa® Gene Therapy, for treating lung cancer. The findings, unveiled at the 2026 American Association for Cancer Research (AACR) Annual Meeting, suggest the therapy could be effective in multiple ways against the disease.
The research, presented by collaborators in San Diego, provides a deeper look into the mechanism of Reqorsa, a gene therapy designed to deliver the TUSC2 tumor suppressor gene to cancer cells. For a clinical-stage company like Genprex, positive preclinical results are a critical step that can validate its scientific platform and build a case for more advanced human trials.
The data highlighted three key areas. First, the biomarkers TROP2 and PTEN may help predict which patients are most likely to respond to Reqorsa. Second, in studies on non-small cell lung cancer (NSCLC) cell lines with a specific ALK-EML4 translocation, Reqorsa was shown to induce apoptosis, or programmed cell death, and decrease tumor volume. Finally, a third study demonstrated that the gene therapy could boost the natural anti-tumor activity of the body’s own Natural Killer (NK) cells.
For investors, this preclinical progress is a significant, albeit early, milestone. It suggests potential for Reqorsa to eventually address a major unmet need in lung cancer, a field crowded with ongoing research. The AACR meeting also featured data from companies like Revolution Medicines, Inc. (NASDAQ: RVMD), which presented encouraging Phase 1 results for its zoldonrasib inhibitor in a subset of NSCLC patients, underscoring the competitive but highly innovative landscape.
For Genprex, these results are crucial for attracting future investment and potential partnerships needed to fund costly later-stage trials. While the company did not disclose its current cash runway, strong preclinical data is fundamental to securing the capital required to advance its pipeline.
