This is a multicenter Phase 1b, open-label study to evaluate the pharmacokinetic, safety and efficacy of binimetinib and encorafenib co-administered to adolescent patients with BRAF V600-mutant advanced/metastatic melanoma. The study consists of a Safety Run-in Phase to determine the RDE (recommended dose in expansion), followed by an Expansion Phase.
Name: binimetinib
Name: encorafenib
Description: Five-point Hedonic scale from 1 to 5, 5=really good
Measure: Palatability score for the pediatric formulations as assessed by an age-appropriate questionnaire for binimetinib Time: Through Cycle 3 Day 1 in patients receiving the pediatric formulations in the Expansion Phase, 28 day cyclesDescription: Five-point Hedonic scale from 1 to 5, 5=really good
Measure: Palatability score for the pediatric formulations as assessed by an age-appropriate questionnaire for encorafenib Time: Through Cycle 3 Day 1 in patients receiving the pediatric formulations in the Expansion Phase, 28 day cyclesAllocation: Non-Randomized
