Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
675 patients were randomized, 337 to vemurafenib and 338 to dacarbazine. One patient randomized to dacarbazine was treated in error with vemurafenib throughout the study and is included in the Vemurafenib arm in the table below and for exposure and safety analyses but was included in the dacarbazine arm for efficacy analyses.

Reporting Groups
  Description
Vemurafenib Participants received continuous oral doses of Vemurafenib (RO5185426) 960 mg twice a day. Patients took four 240 mg tablets in the morning and four 240 mg tablets in the evening (960 mg twice a day for a total daily dose of 1920 mg).
Dacarbazine Dacarbazine was administered intravenously 1000 mg/m˄2 up to 60 minutes on Day 1 of every 3 weeks (3 weeks was one cycle length).
