Exclusion Criteria:

• Patients who have been previously treated with a BRAF and/or MEK inhibitors.

• Patients accepted other administration of anti-cancer study therapies within 4 weeks prior to initiation of dosing;
• Dysphagia，refractory nausea, vomiting, small bowel resection or any other gastrointestinal ailment that would preclude study drug absorption.

• Serious illnesses, such as: cardiovascular disease (uncontrolled congestive heart failure, uncontrolled hypertension, cardiac ischemia, myocardial infarction, and severe cardiac arrhythmia), bleeding disorders, symptomatic autoimmune diseases, severe obstructive or restrictive pulmonary diseases, uncontrolled endocrine disorders (hypothyroidism, hyperthyroidism and diabetes mellitus), retinopathy, active systemic infections, and inflammatory bowel disorders.
