A Phase 3, Randomized, Double-blind Study of Adjuvant Immunotherapy with Relatlimab and Nivolumab Fixed-dose Combination versus Nivolumab Monotherapy after Complete Resection of Stage III-IV Melanoma (BMS CA224-098 RELATIVITY)


General Information

Age Group




Protocol Number


Background Information

The purpose of this study is to see if treating stage III-IV resectable melanoma patients with relatlimab and nivolumab after they have surgery to remove all tumors will reduce the probability of having progressive disease when compared to nivolumab alone. This study will also as assess the possible side effects that this combination therapy might have.

Nivolumab is approved to treat melanoma. Relatlimab is not approved by the Food and Drug Administration (FDA) in the United States or by health authorities in other countries. The combination of relatlimab and nivolomab is considered investigational.
