Eligibility Criteria

        Inclusion Criteria:

          -  Patients must be at least 18 years of age.

          -  Patients must have histologically confirmed melanoma unresectable Stage III or Stage
             IV positive for BRAF V600E, V600K, V600R or V600D by a CLIA approved assay.

          -  Patients must have an ECOG performance status of 0 or 1.

          -  Patients must have adequate baseline organ function as determined by table 2.

        Table 2. Definitions for adequate baseline organ function

        Laboratory Values


          -  ANC (absolute neutrophil count) ≥1.2 × 109/L

          -  Hemoglobin ≥ 9 g/dL

          -  Platelet count ≥100 x 109/L

          -  PT/INR and PTT ≤ 1.3 x ULN (PT = prothrombin time; INR = international normalized
             ratio; PTT = partial thromboplastin time; ULN = upper limit of normal)


          -  Total bilirubin ≤ 1.5 x ULN

          -  AST (aspartate aminotransferase) and ALT (alanine transaminase) ≤ 2.5 x ULN

        Renal -- Serum creatinine ≤ 1.5 mg/dL


        -- Left Ventricular Ejection fraction (LVEF) ≥ LLN (lower limit of normal) by ECHO

        Subjects receiving anticoagulation treatment may be allowed to participate with INR
        established within the therapeutic range prior to randomization.

        If serum creatinine is > 1.5 mg/dL, calculate creatinine clearance using standard
        Cockcroft-Gault formula. Creatinine clearance must be ≥ 50 mL/min to be eligible.

        Except subjects with known Gilbert's syndrome. ECHO scans must be used throughout the study
        when indicated

          -  Patients must be able to provide written informed consent.

          -  Negative serum pregnancy test within 7 days prior to commencement of dosing in
             premenopausal women. Women of non-childbearing potential may be included without serum
             pregnancy test if they are either surgically sterile or have been postmenopausal for ≥
             1 year. Women must use an effective method of contraception from 14 days prior to
             randomization, throughout the treatment period, and for at least 6 months after the
             last dose of study treatment as directed by their physician. Effective methods of
             contraception are defined as those which result in a low failure rate (i.e., less than
             1% per year) when used consistently and correctly (for example implants, injectables,
             or intra-uterine devices). At the discretion of the investigator, acceptable methods
             of contraception may include total abstinence in cases where the lifestyle of the
             patient ensures compliance. (Periodic abstinence [e.g., calendar, ovulation,
             symptothermal, postovulation methods] and withdrawal are not acceptable methods of
             contraception.) Hormonal-based methods (e.g., oral contraceptives) are NOT permitted
             as contraception due to potential drug-drug interactions with dabrafenib.

          -  Patients with brain metastases treated with whole brain radiation that have been
             stable for 2 months are eligible; patients with brain metastases treated with gamma
             knife or surgery are allowed to participate after 2 weeks have elapsed since their
             procedure. Subjects are excluded if they have leptomeningeal or metastases causing
             spinal cord compression that are symptomatic or untreated or not stable for ≥3 months
             (must be documented by imaging) or requiring corticosteroids. Subjects on a stable
             dose of corticosteroids >1 month or who have been off of corticosteroids for at least
             1 week can be enrolled with approval of the medical monitor

          -  Any number and type of prior anticancer therapies are allowed except BRAF or MEK
             inhibitors .

          -  Patients must have discontinued active immunotherapy (IL-2, interferon, CTLA-4, etc.)
             or chemotherapy at least 4 weeks prior to entering the study and oral targeted therapy
             at least 2 weeks prior to entering the study. Patients must not receive any other
             investigational anticancer therapy during the period on study or the four weeks prior
             to entry.

          -  All prior anti-cancer treatment-related toxicities (except alopecia and laboratory
             values as listed in Eligibility Criteria #4) must be Grade 1 according to the Common
             Terminology Criteria for Adverse Events version 4 (CTCAE version 4.03, 2009) at the
             time of starting treatment. Patients that are asymptomatic on low dose maintenance
             hormone replacement delivered at a stable dose for prior toxicities are eligible.

          -  Patient much have measurable disease as defined by RECIST 1.1.

          -  Patients must be able to swallow and retain oral medication and must not have any
             clinically significant gastrointestinal abnormalities that may alter absorption such
