Arms & Interventions
Vemurafenib, 960 mg + Ipilimumab, 10 mg/kg
Participants received vemurafenib, 960 mg, twice daily for 6 weeks (Vem1 Phase). After a washout period of 3-10 days, patients received ipilimumab, 10 mg/kg, every 3 weeks for a maximum of 4 doses. At Week 24, participants received ipilimumab, 10 mg/kg, every 12 weeks until disease progression or unacceptable toxicity. Patients who did not progress or have unacceptable toxicity in the Vem1 Phase were retreated with vemurafenib (Vem 2 Phase) at the last dose level identified at the end of the Vem1 Phase until disease progression or unacceptable toxicity.
Intervention: Ipilimumab (Drug)
Vemurafenib, 960 mg + Ipilimumab, 10 mg/kg

At Week 24, participants received ipilimumab, 10 mg/kg, every 12 weeks until disease progression or unacceptable toxicity. Patients who did not progress or have unacceptable toxicity in the Vem1 Phase were retreated with vemurafenib (Vem 2 Phase) at the last dose level identified at the end of the Vem1 Phase until disease progression or unacceptable toxicity.
Intervention: Vemurafenib (Biological)
Outcomes
Primary Outcomes
Percentage of Participants Who Received Ipilimumab and Who Had Grade 3-4 Drug-related Skin Adverse Events (AEs)
Time Frame: From the first dose date of Vem1 to the last dose of ipilimumab (to a maximum of 3 years) + 90 days or to the first dose date of Vem2, whichever occurred first
AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. Drug-related=having certain, probable, possible, or unknown relationship to study drug. Grading criteria for AEs: Grade 1=Mild, Grade 2=Moderate, Grade 3=Severe, Grade 4=Life-threatening or disabling, Grade 5=Death.
Secondary Outcomes
- Percentage of Participants Who Received Ipilimumab and Who Had Grade 3-4 Drug-related Hepatobiliary Adverse Events(From the first dose date of Vem1 to the last dose of ipilimumab (to a maximum of 3 years) + 90 days or to the first dose date of Vem2, whichever occurred first)
- Percentage of Participants Who Received Ipilimumab and Who Had Grade 3-4 Drug-related Gastrointestinal Adverse Events (AEs)(From the first dose date of Vem1 to the last dose of ipilimumab (to a maximum of 3 years) + 90 days or to the first dose date of Vem2, whichever occurred first)
