Mechanism of action

These drugs work by inhibiting checkpoint proteins (such as PD-1, PD-L1, or CTLA-4) that cancer cells exploit to evade immune detection. By removing these 'brakes' on the immune system, checkpoint inhibitors restore T cell activation and proliferation, enabling durable anti-tumor immunity. This mechanism has proven effective across multiple cancer types.
