Bristol-Myers: Antibody + Opdivo Meets Primary Endpoint of Progression-Free Survival in Melanoma

• First Phase 3 data to be reported from a trial evaluating an anti-LAG-3 antibody

Relatlimab is the company’s third distinct checkpoint inhibitor to demonstrate a benefit for patients

Bristol Myers Squibb (NYSE: BMY) today announced primary results from the Phase 2/3 RELATIVITY-047 (CA224-047) trial evaluating the fixed-dose combination of relatlimab, an anti-LAG-3 antibody, and Opdivo (nivolumab) versus Opdivo alone in patients with previously untreated metastatic or unresectable melanoma. The trial met its primary endpoint of progression-free survival (PFS). Follow up for overall survival, a secondary endpoint, is ongoing. The fixed-dose combination was well-tolerated and there were no new safety signals reported in either the relatlimab and Opdivo combination arm or the Opdivo arm. These are the first Phase 3 data to be reported from a trial evaluating an anti-LAG-3 antibody. Relatlimab is the third distinct checkpoint inhibitor (anti-PD-1, anti-CTLA-4 and anti-LAG-3) for Bristol Myers Squibb and, with Opdivo, the first fixed-dose combination to demonstrate a benefit for patients.
