pidilizumab
A humanized, immunoglobulin (Ig) G1 monoclonal antibody directed against human inhibitory receptor programmed cell death 1 (PD-1; PDCD1), with potential immune checkpoint inhibitory and antineoplastic activities. Pidilizumab binds to PD-1 and blocks the interaction between PD-1 and its ligands, PD-1 ligand 1 (PD-L1) and PD-1 ligand 2 (PD-L2). This prevents the activation of PD-1 and its downstream signaling pathways. This may restore immune function through the activation of natural killer (NK) cells and cytotoxic T-lymphocytes (CTLs) against tumor cells. PD-1, an inhibitory receptor belonging to the B7-receptor family expressed on activated T-lymphocytes, B-cells and NK cells, negatively regulates T-cell activation and effector function when activated by its ligands; it plays an important role in tumor evasion from host immunity. Check for active clinical trials using this agent. (NCI Thesaurus)
