Mechanism of action

Nivolumab and pembrolizumab are monoclonal antibodies that bind to programmed death receptor-1 (PD-1) on T cells, preventing interaction with PD-L1 and PD-L2 ligands on tumor cells. This blockade releases the 'brakes' on the immune system, restoring T-cell proliferation, activation, and anti-tumor function. By reinvigorating exhausted T cells, these drugs enable durable anti-tumor immunity across multiple cancer types.
