Study to determine the effectiveness of GSK1120212 in BRAF mutation-positive melanoma previously treated with or without a BRAF inhibitor
Trial overview
Number of participants with best confirmed response
Timeframe: From Baseline (Day 1) until the time of the first documented evidence of a confirmed complete response or partial response (up to approximately 25 weeks)
Number of participants with best confirmed response in the indicated subgroups of participants previously treated with standard therapy but not BRAF inhibitors
Timeframe: From Baseline (Day 1) until the time of the first documented evidence of a confirmed CR or PR (up to approximately 25 weeks)
Number of participants with best unconfirmed response at the time of the interim analysis (Week 8)
Timeframe: Week 8
Mean plasma concentrations
Timeframe: Day 15, pre-dose, 0.5-2 hours (hrs) post-dose, 2-4 hrs post-dose, and 4-8 hrs post-dose; Week 4, pre-dose; Week 8, pre-dose; Week 12, pre-dose
Number of participants with any Adverse Event (AE)
Timeframe: From the date of the first dose of study medication until 28 days after the last dose (up to 477 days)
Duration of Tumor Response
Timeframe: From the time of the first documented evidence of a confirmed CR or PR until disease progression or death due to any cause (up to approximately 40 weeks)
Progression-free survival (PFS)
Timeframe: Baseline (Day 1) until the time of disease progression or death due to any cause (up to approximately 57 weeks)
PFS in the indicated subgroups of participants previously treated with standard therapy but not BRAF inhibitors
Timeframe: Baseline (Day 1) until the time of disease progression or death due to any cause (up to approximately 57 weeks)
Overall Survival
Timeframe: Baseline (Day 1) until death due to any cause (up to 134 weeks)
Number of participants who survived until 6 months, 12 months and 24 months from Baseline
Timeframe: Month 6, Month 12 and Month 24
Number of participants with tumor progression
Timeframe: Baseline (Day 1) until tumor progression (up to approximately 57 weeks)
