OS Therapies (NYSE:OSTX) ("OS Therapies" or "the Company"), a clinical-stage immunotherapy and Antibody Drug Conjugate biopharmaceutical company, is pleased to invite investors to a webinar on February 27, 2025, at 4:15 p.m. ET.

The exclusive event, hosted by RedChip Companies, will feature OS Therapies' Chairman and CEO, Paul Romness, and Chief Business Officer, Gerald Commissiong, who will provide an in-depth update on the Company's rapidly advancing pipeline. OS Therapies is pioneering groundbreaking immunotherapies and antibody-drug conjugates (ADCs) to address critical unmet needs in pediatric and young adult oncology, as well as a broad range of solid tumors. The Company's lead candidate, OST-HER2, has demonstrated statistically significant improvements in 12-month event-free survival for recurrent, fully resected metastatic osteosarcoma, positioning it as a potential first-in-class treatment with accelerated FDA approval pathways. Additionally, OS Therapies' proprietary Tunable Antibody Drug Conjugate (tADC) platform, powered by SiLinker™ technology, has shown promising preclinical efficacy in ovarian and other HER2-positive cancers. With multiple upcoming clinical and regulatory milestones, potential revenue streams from licensing agreements, and a possible Priority Review Voucher (PRV) worth approximately $150 million, OS Therapies is strategically positioned for significant growth and value creation.

A live Q&A session with Romness and Commissiong will follow the presentation.
