Tawbi et al. recently reported improvement in progression-free survival (PFS) with the relatlimab–nivolumab combination over nivolumab monotherapy in previously untreated, unresectable/metastatic melanoma. The nivolumab–ipilimumab combination has improved the response rate in advanced melanoma with a significant increase in grade 3/4 adverse events (55%), making its real-world application difficult. Hence, the incidence of grade 3/4 adverse events with the relatlimab–nivolumab combination (18.9%) appears encouraging. Nevertheless, 30.4% (108/355) patients discontinued the combination treatment due to reasons other than disease progression. Hence, predictive models or biomarkers for appropriate patient selection are crucial to explore.
For BRAF-mutant melanoma, combination therapy with BRAF/MEK inhibitors is an acceptable first-line strategy. Among 38.5% (275/714) patients positive for BRAF mutations, subsequent systemic therapy with BRAF/MEK inhibitors could be started in only 19.3% (91/470) after discontinuing study treatment. Combination of programmed cell death protein 1 blockade with BRAF/MEK inhibition has also been explored in advanced melanoma with improved survival outcome. With preclinical evidence suggesting proimmunogenic effect of MEK inhibition, it is important to investigate the combination of LAG3 blockade with BRAF/MEK inhibition in advanced BRAF-mutant melanoma.
