Mechanism of action

From the NCI Drug Dictionary (for relatlimab): A monoclonal antibody directed against the inhibitor receptor lymphocyte activation gene-3 (LAG-3), with potential immune checkpoint inhibitory and antineoplastic activities. Upon administration, relatlimab binds to LAG-3 on tumor infiltrating lymphocytes (TILs). This may activate antigen-specific T lymphocytes and enhance cytotoxic T cell-mediated tumor cell lysis, which leads to a reduction in tumor growth.
