anti-TIM-3 monoclonal antibody Sym023

A recombinant, fully human monoclonal antibody against the inhibitory T-cell receptor T-cell immunoglobulin and mucin domain-containing protein 3 (TIM-3; TIM3; hepatitis A virus cellular receptor 2; HAVCR2), with potential immune checkpoint inhibitory and antineoplastic activities. Upon administration, the anti-TIM-3 monoclonal antibody Sym023 binds to TIM-3 expressed on certain T cells, including tumor infiltrating lymphocytes (TILs). This abrogates T-cell inhibition, activates antigen-specific T lymphocytes and enhances cytotoxic T-cell-mediated tumor cell lysis, which results in a reduction in tumor cell proliferation. TIM-3, a transmembrane protein and immune checkpoint receptor, is associated with tumor-mediated immune suppression.
