Relatlimab is a monoclonal antibody designed for the treatment of melanoma.[2][3] It is used in combination with nivolumab to treat melanoma.[1][4]

Relatlimab is a Lymphocyte activation gene-3 (LAG-3) inhibitor.[1][4] It is under development by Bristol-Myers Squibb.[1][4] It is made using Chinese hamster ovary cells.[1]


As of 2018, relatlimab is undergoing Phase II/III trials.[5]

The combination nivolumab/relatlimab (Opdualag) was approved for medical use in the United States in March 2022.[1][4]
