• Positive Preclinical Data

  Research collaborators will present positive preclinical data for Reqorsa Gene Therapy (quaratusugene ozeplasmid) at the 2026 American Association for Cancer Research (AACR) Annual Meeting.

• Biomarker Identification

  Studies identified TROP2 and PTEN as potential biomarkers for primary resistance to TUSC2 gene therapy in non-small cell lung cancer (NSCLC), which could refine patient selection strategies.

• Enhanced Efficacy in ALK+ NSCLC

  Quar Oze-driven TUSC2 overexpression induced apoptosis and significantly curtailed tumor growth in ALK-positive NSCLC models, showing improved outcomes in combination with alectinib, including in resistant settings.

• Boosted Antitumor Immunity

  Findings suggest TUSC2 acts as a critical enhancer of innate antitumor immunity by boosting NK cell cytotoxic function, leading to tumor suppression and, in many cases, complete tumor elimination in preclinical models.

This filing is highly significant for Genprex, a nano-cap biotechnology company, as it provides crucial positive preclinical data for its lead drug candidate, Reqorsa Gene Therapy (quaratusugene ozeplasmid). The identification of TROP2 and PTEN as potential biomarkers for resistance in non-small cell lung cancer (NSCLC) is a pivotal development, offering insights that could refine patient selection and optimize therapeutic efficacy in future clinical settings. Furthermore, the studies demonstrate Reqorsa's ability to induce apoptosis in ALK-positive NSCLC, showing improved outcomes when combined with alectinib, even in resistant models. The findings also highlight Reqorsa's role in boosting NK cell cytotoxicity and innate antitumor immunity, suggesting a dual-function therapeutic approach. For a company with a market capitalization of under $5 million, such robust preclinical results for a lead candidate are critical for attracting investment, extending its operational runway, and progressing towards clinical trials, directly addressing the "going concern" risks often faced by early-stage biotechs.
