OS Therapies Inc. reported positive biomarker data from its Phase 2b trial of OST-HER2 for treating pulmonary metastatic osteosarcoma. The data showed that immune blood biomarkers in the interferon gamma pathway can distinguish long-term survivors from short-term ones. The company is preparing submissions for regulatory approval in the UK, US, and Europe, targeting 2026. OST-HER2 has received multiple designations from the FDA and EMA, including Orphan Disease and Fast Track Designations.
