Mechanism of action

AK156 binds to programmed death receptor 1 (PD-1) on T cells, preventing interaction with its ligands (PD-L1 and PD-L2) expressed on tumor cells and immune cells. This blockade releases the brake on T cell-mediated immunity, allowing enhanced proliferation, activation, and cytotoxic function against cancer cells. The mechanism is similar to other PD-1 inhibitors used in immuno-oncology.
