Mechanism of action

MEDI4736 (durvalumab) binds to programmed death ligand-1 (PD-L1) on tumor cells and immune cells, blocking the inhibitory PD-L1/PD-1 axis that tumors exploit to evade immune surveillance. By preventing this interaction, the drug restores T-cell activation and proliferation, enabling the immune system to recognize and attack cancer cells. This mechanism is particularly effective in tumors with high PD-L1 expression.
