Mechanism of action

FKB327 is designed to bind both PD-L1 and TIM-3 ligand (CEACAM1), blocking inhibitory signals on tumor-infiltrating T cells. By simultaneously targeting two complementary immune checkpoint pathways, the drug aims to overcome resistance mechanisms and achieve more robust anti-tumor immunity than single-checkpoint inhibitors.
