End of Phase 2 Meeting with FDA scheduled for August 27, 2025 to review OST-HER2 recurrent, pulmonary metastatic osteosarcoma program
“We are making significant progress towards our primary objective of obtaining regulatory approval for OST-HER2 in recurrent, pulmonary metastatic osteosarcoma prior to the sunsetting of the rare pediatric disease priority review voucher (“PRV”) program,” said Paul Romness, MPH, Chairman & CEO of OS Therapies. “If successful, we expect to receive significant non-dilutive funding from the sale of the PRV which we would then be able to deploy in commercializing OST-HER2 osteosarcoma and other HER2 expressing cancers, as well as advance the other clinical candidates in our pipeline, including OST-504 in prostate cancer. We strongly believe in the promise of the listeria immunotherapy platform to help prevent and treat cancer, and intend to judiciously deploy our capital to focus on the OST-HER2 approval while advancing our other clinical programs without deploying significant capital or running other clinical studies while we wait for the OST-HER2 approval and related PRV sale.”
