Conditions

Metastatic or unresectable locally advanced BRAF V600E/K mutation positive melanoma

Brief summary

Safety Lead-In: Incidence of DLTs., Randominzed Phase 3: OR, defined as confirmed BOR of either CR or PR, as determined by BICR assessment per RECIST v1.1 from randomization to the earliest of PD, start of subsequent anticancer therapy, or death due to any cause

Detailed description

1. Safety Lead-In: Incidence and severity of AEs graded according to the NCI CTCAE v4.03* and changes in clinical laboratory parameters, vital signs, and cardiac assessments., 2. Safety Lead-In: OR, PFS, DC, TTR, 3. Safety Lead-In: Plasma concentration-time profiles and PK parameter estimates for encorafenib and binimetinib., 4. Randomized Phase 3: PFS, defined as the time from the date of randomization to the date of first documented disease progression, as determined by BICR assessment per RECIST v1.1, or death due to any cause, whichever occurs first.
