anti-PD-L1 monoclonal antibody MPDL3280A
A human, Fc optimized, monoclonal antibody directed against the protein ligand PD-L1 (programmed cell death-1 ligand 1) with potential immunomodulating and antineoplastic activities. Anti-PD-L1 monoclonal antibody MPDL3280A binds to PD-L1, blocking its binding to and activation of its receptor, PD-1 (programmed death 1), which may enhance the T-cell-mediated immune response to neoplasms and reverse T-cell inactivation. In addition, by binding to PD-L1, MPDL3280A also prevents binding of this ligand to B7.1. PD-L1 is overexpressed on many human cancer cell types. PD-L1 binding to PD-1 on T-cells suppresses the immune system and results in increased immune evasion. PD-1, a transmembrane protein expressed on activated T-cells, is a negative regulator of the immune system that limits the expansion and survival of CD8+ T cells. The Fc region of MPDL3280A is modified in such a way that it does not induce either antibody-dependent cytotoxicity (ADCC) or complement-dependent cytotoxicity (CDC). Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
