Mechanism of action

Toripalimab binds to programmed death receptor 1 (PD-1) on T cells, preventing interaction with PD-L1 and PD-L2 ligands expressed by tumor cells and immune cells. This blockade reverses T cell exhaustion and restores anti-tumor immune responses. It is a humanized IgG4 monoclonal antibody designed to enhance endogenous anti-tumor immunity.
