Description of intervention(s) / exposure
Treatment: Drugs - Dabrafenib
Treatment: Drugs - Trametinib

Experimental: Dabrafenib and Trametinib - Dabrafenib 150mg bid orally and Trametinib 2mg od orally for 52 weeks

Key exclusion criteria
* Known mucosal or ocular melanoma or any unresectable in-transit metastases
* Evidence of distant metastatic disease on screening evaluation
* Prior anti-cancer treatment for melanoma (chemotherapy, immunotherapy, biologic therapy, vaccine therapy, investigational treatment or radiotherapy). Prior surgery for melanoma is allowed.
* Taken an investigational drug within 28 days or 5 half-lives, whichever is longer, prior to commencing study treatment.
* Current or expected use of a prohibited medication(s)
* Known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to the study treatments, their excipients, and/or dimethyl sulfoxide (DMSO)
* Known HIV
* A history of known glucose-6-phosphate dehydrogenase (G6PD) deficiency
* History of another malignancy or a concurrent malignancy except:

1. Patients who have been disease-free for 3 years and have a life expectancy of > 5 years;
2. Patients with a history of completely resected non-melanoma skin cancer or successfully treated in situ carcinoma are eligible, for example cervical cancer in situ, atypical melanocytic hyperplasia or melanoma in situ, multiple primary melanomas.
* A history or evidence of cardiovascular risk including any of the following: a. QT interval corrected for heart rate using the Bazett's formula =480 msec or = 450 msec for patients with bundle branch block; b. History or evidence of current clinically significant uncontrolled arrhythmias; c. History of acute coronary syndromes (including myocardial infarction or unstable angina), coronary angioplasty, or stenting within 6 months prior to commencement of study treatment; d. History or evidence of current = Class II congestive heart failure; e. Abnormal cardiac valve morphology documented by echocardiogram which in the opinion of the investigator could interfere with the patient's safety.

f. Treatment refractory hypertension defined as a blood pressure of systolic > 140 mm Hg and/or diastolic > 90 mm Hg which cannot be controlled by anti-hypertensive therapy.
* A history or current evidence/risk of retinal vein occlusion (RVO) or central serous retinopathy (CSR)
* Any serious or unstable pre-existing medical conditions (aside from the malignancy exceptions specified above), psychiatric disorders, or other conditions that, in the opinion of the treating clinician, could interfere with the patient's safety, obtaining informed consent, or compliance with study procedures.
* Breastfeeding females
