A phase 3 randomized clinical trial comparing vemurafenib with dacarbazine in 675 patients with previously untreated, metastatic melanoma with the BRAF V600E mutation....At 6 months, overall survival was 84% (95% confidence interval [CI], 78 to 89) in the vemurafenib group and 64% (95% CI, 56 to 73) in the dacarbazine group....Response rates were 48% for vemurafenib and 5% for dacarbazine….Vemurafenib produced improved rates of overall and progression free survival in patients with previously untreated melanoma with the BRAF V600E mutation.
