Class/mechanism: PD-L1 blocking antibody. PD-L1 (programmed death-1 ligand 1) expressed on tumor cells and tumor-infiltrating immune cells can result in inhibition of anti-tumor immune responses. Durvalumab binds to PD-1 and CD80 (B7.1) receptors on T-cells and antigen presenting cells and prevents PD-L1's inhibitory effects on the immune system. As a result, durvalumab stimulates immune responses, including anti-tumor immune effects.
