Dallas, Texas-(Newsfile Corp. - September 8, 2025) - OS Therapies Inc. (NYSE American: OSTX): Stonegate Capital Partners initiates their coverage on OS Therapies Inc. (NYSE American: OSTX). OS Therapies advanced meaningful clinical, regulatory, and financial milestones in 2Q25 as it moves closer to bringing OST-HER2 to patients with recurrent, fully resected, pulmonary metastatic osteosarcoma. Importantly, the FDA confirmed that OST-HER2 meets the biological definition of a Regenerative Medicine Advanced Therapy (RMAT) and issued a Biologics License Application (BLA) number in preparation for an Accelerated Approval submission. Final 12-month Event Free Survival (EFS) results from the Phase 2b trial demonstrated statistically significant improvement, supported by interim 2-year Overall Survival (OS) data, further validating the clinical benefit. With a U.S. commercial partnership secured with Eversana, OS Therapies is positioning for a potential U.S. launch in the first half of 2026.
