Tislelizumab (BeiGene) is a humanized monoclonal antibody that was designed to bind to the PD-1 receptor and prevent binding of PD-L1. In addition, tislelizumab was designed to minimize binding to Fc-gamma-receptors (FcyR) on macrophages. Preclinical studies found that binding to FcyR on macrophages compromises the anti-tumor activity of PD-1 antibodies through activation of antibody-dependent macrophage-mediated killing of T effector cells.
