Mechanism of action

JS004 blocks CTLA-4, a negative regulator of T-cell activation, while toripalimab blocks PD-1, another inhibitory checkpoint. Together, they remove multiple brakes on the immune system, allowing T cells to more effectively recognize and attack cancer cells. This dual checkpoint inhibition approach is designed to overcome resistance to single-agent immunotherapy.
