Vibostolimab is an anti-TIGIT (T cell immunoglobulin and ITIM domain) monoclonal antibody. Vibostolimab shows antitumor activity, and can be used in non-small cell lung cancer (NSCLC) and melanoma research[1].
Vibostolimab binds to TIGIT and blocks the interaction between TIGIT and its ligands (CD112 and CD155), activating T lymphocytes which help to destroy tumor cells[1].
