“The assets being acquired from Ayala complete OS Therapeutics’ ownership of the key intellectual property underlying our listeria monocytogenes immunotherapy platform, as well as bolster our development pipeline with the addition of clinical-stage lung cancer and prostate cancer immunotherapy assets,” said Paul Romness, MHP, Chairman & CEO of OS Therapies. “Importantly, this agreement eliminates certain near-term milestone payment obligations related to OST-HER2 in osteosarcoma, projected sales milestone payments, and significantly reduces our effective royalty rate. As a result, we have enhanced both the clinical and financial prospects for the Company with minimal impact to our cash position. The elimination of these milestones payment obligations and reduction in royalties obligations significantly improves the net present value of the OST-HER2 program while also improving our negotiating position with potential partners. Taken together, this agreement bolsters our financial and partnership prospects.”

OS Therapies anticipates requesting Biologics Licensing Authorization (BLA) for OST-HER2 in osteosarcoma in the second quarter of 2025, and hopes to be granted a BLA and related Priority Review Voucher (PRV) from FDA by the end of 2025. Additionally, the Company intends to sell the PRV immediately upon issuance and does not intend to initiate any new clinical development programs until it has completed interactions with FDA around OST-HER2 in osteosarcoma.
Under the terms of the agreement, OS Therapies has agreed to pay $0.5 million in cash and issue $7.5 million worth of OS Therapies’ common shares to Ayala. The transaction is expected to close 60 days from execution of the agreement, subject to customary closing conditions.

OS Therapies previously disclosed that it completed a $7.1 million financing, priced at $4.00 per share primarily with existing shareholders, that provides the Company with sufficient cash runway into 2026 inclusive of payments to Ayala. Under the terms of the financing agreement, OS Therapies is prohibited from issuing shares to raise capital for at least 6 months and suspended the issuance of shares to raise capital under its equity line of credit so long as the price of the common stock is below $12.00. The Company’s burn rate is now approximately $0.4M per month.
As part of the financing agreement, OS Therapies agreed to appoint Karim Galzahr to the Company’s Board of Directors. Galzahr is managing partner at OKG Capital, a medtech and life science investor. Galzahr brings over 30 years of experience in all aspects of finance including M&A, asset management, corporate development and strategic advisory work across the technology sector and medical technology sectors.

“I am honored to join the OS Therapies Board of Directors at such a pivotal moment in the Company’s journey,” said Galzahr, newly appointed Board Member of OS Therapies. “With compelling Phase 2b osteosarcoma data, the anticipated FDA approval of OST-HER2, and the potential to earn a saleable Priority Review Voucher, the Company is positioned to unlock the full potential of its market leading listeria-based immunotherapy platform. This acquisition not only strengthens its intellectual property portfolio but also clears financial hurdles, paving the way for groundbreaking work in osteosarcoma and expanding opportunities in lung and prostate cancer. I look forward to contributing to OS Therapies’ mission of transforming cancer care and improving patient outcomes worldwide.”
