OS Therapies Receives Rare Pediatric Disease Designation (RDD) in Osteosarcoma for OST-HER2 (Listeria monocytogenes)

CAMBRIDGE, Md., Nov. 3, 2021 /PRNewswire/ — OS Therapies, a research and clinical-stage biopharmaceutical company whose lead program uses OST-HER2 (Listeria monocytogenes) is being developed for therapies to treat and cure Osteosarcoma (OS), today announced the U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease Designation (RDD) for OST-HER2 (OST31-164) for the treatment of Osteosarcoma. 

"The timing and determination by the FDA that OST-HER2 is a potentially much-needed new treatment in this underserved disease underscores the importance of our recently initiated PhIIb clinical trial in recurred, resected Osteosarcoma" said Paul Romness, CEO of OS Therapies. "The RDD ensures a well-deserved expedited review by the FDA, as well as a Priority Review Voucher (PRV) if our current trial is successful."

The FDA grants RDD (Rare Disease Designation) status for serious and life-threatening diseases that primarily affect children ages 18 years or younger and involves fewer than 200,000 people in the U.S. In addition to expedited review, if a PRV (Priority Review Voucher) is issued it can – at the election of OS Therapies – be transferred to larger Pharmaceutical and Biotechnology companies for a cash or other benefit-in-kind.

"The entire team at OS Therapies has been working diligently through a global pandemic to address the necessary regulatory hurdles in order to get this technology to pediatric patients as soon as possible," said Dr. Colin Goddard, Executive Chair of OS Therapies. "Not only are we addressing an unmet medical need, but the PRV and expedited review will have significant financing advantages that will enable us to support our ever-expanding pipeline for patients with other solid tumors."

About Osteosarcoma
Osteosarcoma is a solid tumor of the bone that predominantly occurs in adolescent and young adults (AYA). Standard treatment includes surgery and chemotherapy.  For patients with initially metastatic or recurrence after chemotherapy, there is a significantly poorer prognosis.

About OST-HER2

OST-HER2 has received a USDA provisional approval for treatment of Osteosarcoma in canines. In a completed phase III study in canines (n=180), there was a clear separation of treated and untreated patients (p=.0007) in Overall Survival (OS) and Disease Progression.
