Durvalumab (Imfinzi)
General information
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 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. Durvalumab is being investigated for potential use as monotherapy or in combination with tremelimumab (ticilimumab) in non-small cell lung cancer, head and neck cancer, bladder cancer, gastric cancer, pancreatic cancer, hepatocellular carcinoma, and blood cancers.[1]
