Key Points Question Following the US Food and Drug Administration’s approval of PD-1 immune checkpoint inhibitors (ICI) for metastatic melanoma, what were the utilization and overall survival associated with ICI in the first-line setting after 2015? Findings In this cohort study of 16 831 patients with metastatic melanoma, first-line immunotherapy use increased from 2010 to 2019, although 38% of patients still were not receiving first-line ICI in 2019. Use of ICI was associated with improvements in survival, even among those with brain metastases. Meaning First-line ICI therapy was associated with substantial improvements in overall survival among patients with metastatic melanoma, but rates of use remain suboptimal.
