Bristol Myers Squibb’s Opdualag – a new, first-in-class, fixed-dose combination of nivolumab and relatlimab, administered as a single intravenous infusion – was approved by the U.S. Food and Drug Administration for the treatment of adult and pediatric patients 12 years of age or older with unresectable or metastatic melanoma.

An experimental Bristol Myers Squibb drug from a new class of immunotherapy used in combination with the company’s big-selling cancer medicine Opdivo significantly extended the time it took for advanced melanoma to worsen compared with Opdivo alone, according to early data from a study released on May 19.
