Passive Immune-oncology Therapy (New Antibody Drug)
OBI-888 is a novel first-in-class monoclonal antibody, which selectively targets Globo H, an antigen expressed in up to 15 epithelial cancers. This Globo H targeting antibody has been shown to induce tumor-killing via antibody dependent cell-mediated cytotoxicity (ADCC), antibody-dependent cell-mediated phagocytosis (ADCP), and complement dependent cytotoxicity (CDC).
OBI-888 is also anti-immunosuppressive and anti-angiogenic. In pre-clinical xenograft animal models in multiple tumor types (pancreatic, colon, lung, and breast), OBI-888 has demonstrated tumor shrinkage at various doses. In pre-clinical single and repeated dose toxicology studies, OBI-888 was well-tolerated, and no adverse effect was found in all the doses tested. OBI Pharma owns global rights to OBI-888.
