CLINICAL AND REGULATORY

European Commission approves BMS’s LAG3 blocker

Six months after approval by FDA, the EC approved Opdualag nivolumab/relatlimab from BMS to treat unresectable or metastatic melanoma with tumor cell PD-L1 expression <1%. Opdualag, a fixed dose combination of relatlimab and the pharma’s marketed PD-1 inhibitor Opdivo nivolumab, is the first drug targeting LAG3 to have received regulatory approval. The EC’s decision is based upon an exploratory analysis of results from the Phase 2/3 RELATIVITY-047 trial in patients with tumor cell expression < 1%, which demonstrated that treatment with the fixed-dose combination of the PD-1 inhibitor nivolumab and novel LAG-3-blocking antibody relatlimab more than doubled the median progression-free survival (PFS) compared to nivolumab monotherapy – an established standard of care. No new safety events were identified with the combination when compared to nivolumab monotherapy. The EC decision allows for the use of Opdualag for the first-line treatment of adults and adolescents 12 years of age and older with advanced melanoma and tumor cell PD-L1 expression < 1% in all European Union member states*, as well as Iceland, Liechtenstein, and Norway.
