Screening

• Melanoma confirmed centrally to be BRAF V600E/K mutation-positive;

• No more than 12 weeks elapsed between full surgical resection (including SLNB) and randomization;

• Recovered from definitive surgery (e.g., complete wound healing, no uncontrolled wound infections or indwelling drains);

• ECOG performance status of 0 or 1;

• Adequate haematological function as defined as Absolute neutrophil count (ANC) ≥ 1.5 x 109/L, Platelets ≥ 100 x 109/L and Hemoglobin

≥ 9.0 g/dL;

• Adequate renal function as defined as Serum creatinine ≤ 1.5 × ULN; or calculated creatinine clearance ≥ 50 mL/min;

• Adequate electrolytes, defined as serum potassium and magnesium levels within institutional normal limits;

• Adequate hepatic function as defined as Serum total bilirubin ≤ 1.5 x ULN and < 2 mg/dL, Alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) ≤ 2.5 x ULN;

• Adequate cardiac function as defined as LVEF ≥ 50% as determined by MUGA scan or echocardiogram and Mean triplicate QTcF value ≤ 480 msec and no history of QT syndrome;

• Adequate coagulation function, defined as INR ≤1.5× ULN unless the patient is receiving anticoagulant therapy as long as PT or aPTT is within the therapeutic range;

• Negative serum β-HCG test (female patient of childbearing potential only) performed within 3 days prior to Day 1;

• Female patients of child-bearing potential and male patients must agree to follow the protocol's contraception guidance during the treatment period and for ≥30 days after last administration.

Exclusion Criteria:

Pre-screening

• Unknown ulceration status;

• Uveal and mucosal melanoma;
