After 3months, patients without progressive disease (PD) were randomly assigned (1:1) to continue vemurafenib + cobimetinib (Arm A) or switch to atezolizumab (Arm B) until first documented PD (PD1). Primary outcome was PFS1 (time from start of run-in until PD1 or death). OS and safety were also assessed.Of 185 patients enroled between November 2016 and December 2019, 135 were randomly assigned after the run-in period (Arm A, n = 69; Arm B, n = 66). Median PFS1 was significantly longer in Arm A versus Arm B (13.9 versus 5.9months; hazard ratio [HR] 0.55; 95 %K Checkpoint inhibition (Other) %K First-line (Other) %K Melanoma (Other) %K Run-in (Other) %K Sequence (Other) %K Targeted therapy (Other) %F PUB:(DE-HGF)16 %9 Journal Article %$ pmid:37482012 %R 10.1016/j.ejca.2023.112941 %U https://inrepo02.dkfz.de/record/277708
