More Details of OS Therapies Inc Company

OS Therapies Incorporated is a clinical-stage biopharmaceutical company. The Company is focused on the identification, development and commercialization of treatments for Osteosarcoma (OS) and other solid tumors. It built a pipeline of product candidates targeting multiple indications for solid cancers. Its pipeline includes two drug technologies: OST-HER2 and OST-tADC. OST-HER2 is an off-the-shelf immunotherapy, which is a type of cancer treatment that helps one’s immune system fight cancer, comprised of a genetically weakened and modified strain of Listeria monocytogenes, a species of bacteria that causes the infection listeriosis, that expresses HER2 peptides. OST-tADC is a tunable ADC with a plug-and-play platform that features tunable pH sensitive silicone linkers (SiLinkers). The payloads can include antibodies, chemotherapeutics, cytotoxins and potentially mRNA treatments directly into and in the vicinity of solid tumors.
