Mechanism of action

  • From the NCI Drug Dictionary: An immunoglobulin G4 (IgG4), humanized monoclonal antibody directed against the immunosuppressive ligand programmed cell death-1 ligand 1 (PD-L1; cluster of differentiation 274; CD274), with potential immune checkpoint inhibitory and antineoplastic activities. Upon administration, adebrelimab specifically targets and binds to PD-L1, blocking its binding to and activation of its receptor programmed death 1 (PD-1). This reverses T-cell inactivation caused by PD-1/PD-L1 signaling and enhances the cytotoxic T-lymphocyte (CTL)-mediated anti-tumor immune response against PD-L1-expressing tumor cells.
