A humanized IgG1 monoclonal antibody directed against the cell surface glycoprotein CD-38 with potential antineoplastic activity. Anti-CD38 monoclonal antibody SAR650984 specifically binds to CD38 on CD38-positive tumor cells. This may trigger antitumoral antibody-dependent cellular cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC) and apoptosis eventually leading to cell lysis in CD38-expressing tumor cells. CD38, a type II transmembrane glycoprotein, is present on various immune cells and hematologic malignancies, and its expression has been correlated with poor prognosis. Check for active clinical trials using this agent. (NCI Thesaurus)
