Background and Date of Approval

Durvalumab is an anticancer drug that belongs to the category of medicines known as Anti-PD-1 monoclonal antibodies. It was approved by the FDA in May 2017 to treat certain types of cancer.

It works by blocking a protein called programmed death-ligand 1 (PD-L1), which is found on the surface of certain cancer cells.
