Placebo Comparator
Part 1: Safety run-in Cohort
Part 2: Biomarker cohort
Part 3- Arm 1: Spartalizumab in combination with dabrafenib and trametinib
Part 3- Arm 2: Placebo in combination with dabrafenib and trametinib
In Part 1, participants are treated at different dose levels to determine the recommended Phase 3 regimen of spartalizumab in combination with dabrafenib and trametinib. The starting dose of spartalizumab is 400 mg Q4W in combination with the approved dose of dabrafenib (150 mg BID) and trametinib (2 mg QD).
In Part 2, participants are treated with spartalizumab 400 mg Q4W in combination with the approved dose of dabrafenib (150 mg BID) and trametinib (2 mg QD).
In Part 3, participants are randomized to receive spartalizumab at the RP3R identified in Part 1 (400 mg Q4W) in combination with approved dose of dabrafenib (150 mg BID) and trametinib (2 mg QD)
In Part 3, participants are randomized to receive matching placebo in combination with the approved dose of dabrafenib (150 mg BID) and trametinib (2 mg QD)
