The FDA has approved Roche’s Tecentriq (atezolizumab) plus Cotellic (cobimetinib) and Zelboraf (vemurafenib) for the treatment of BRAF V600 mutation-positive advanced melanoma patients. The safety profile observed in the Tecentriq combination was consistent with the known safety profiles of the individual medicines.
