Mechanism of action

HLX10 targets programmed death ligand 1 (PD-L1) on tumor cells and immune cells, preventing the PD-L1/PD-1 interaction that normally suppresses T-cell activation. By blocking this immune checkpoint, the drug allows cytotoxic T lymphocytes to recognize and attack cancer cells more effectively. This mechanism is used across multiple solid tumors where PD-L1 expression is associated with immune evasion.
