Study of Olaparib and Durvalumab in IDH-Mutated Solid Tumors

Olaparib is a drug that blocks a protein called poly (ADP-ribose) polymerase (PARP). PARP is important in the growth and spread of cancer cells. Because of this, blocking PARP from working is expected to stop the growth of or shrink cancer cells.

Durvalumab is a drug that works by stopping a protein called Programmed Cell Death Ligand 1 (PD-L1) from working. PD-L1 is a protein that is thought to prevent the immune system (the body's defense against diseases) from killing cancer cells. Stopping PD-L1 from working is expected to allow the immune system to once again prevent or slow down cancer growth.
