Nivolumab + Relatlimab Continues Clinical Benefit in Advanced Melanoma
Source: Oncology times, April 2022
The combination of nivolumab and relatlimab continues to demonstrate a progression-free survival (PFS) benefit compared to nivolumab alone in patients with previously untreated metastatic or unresectable melanoma. In addition, for the first time, the dual checkpoint inhibitor therapy also demonstrated a higher overall response rate (ORR), according to follow-up data from the RELATIVITY-047 trial.
Previously, the RELATIVITY-047, a global, randomized, double-blind, Phase II/III study, had met its primary endpoint of PFS after 13.2 months follow-up (J Clin Oncol 2021; doi: 10.1200/JCO.2021.39.15_suppl.9503). Relatlimab, a human LAG-3 blocking antibody, and nivolumab, an anti-PD-1 agent, as a fixed-dose combination demonstrated a significant PFS benefit, with a median PFS of 10.1 months with the combination versus 4.6 months with nivolumab monotherapy, with a manageable safety profile.
