This is a dose-seeking and efficacy study of combined BRAF Inhibitor Vemurafenib and High-dose Interferon alfa-2b for therapy of advanced melanoma.
* Dose-selection and dose-expansion study of combination therapy with high-dose interferon alfa-2b and vemurafenib. * Vemurafenib at standard dosing with a 2 week lead-in period to exploit potential immunomodulatory effects. Concurrent HDI following this (week 2 onwards) at standard induction (4 weeks) and maintenance (48 weeks) doses. * Modified Storer's "up and down" dose escalation schema using 3 fixed dose levels for HDI and a fixed sample size that allows efficient identification of recommended phase II dose. * 36-63 patients will be enrolled depending on toxicity parameters. oIn the dose-selection portion, 3 patients will be enrolled per dose level, starting from the lowest dose level. Enrollment will occur serially allowing for the observation of toxicity during the observation period. oIterative enrollment of up to 3 subjects per cohort will be continued until a total of 30 evaluable subjects have been enrolled. oThe dose level at which the RLT rate is the closest to 1/3 will be considered as RP2D. oDuring the dose-expansion portion of the trial, depending on the number of patients treated at RP2D during the dose-selection portion, additional patients may be enrolled - the accrual target is 36 patients treated at RP2D.

•Vemurafenib at standard dosing with a 2 week lead-in period to identify potential effects. IFNα-2b following this (week 2 onwards) at standard induction (4 weeks) and maintenance (48 weeks) doses.
Vemurafenib is a prescription medicine used to treat melanoma, that has spread to other parts of the body or cannot be removed by surgery, and that has a certain type of abnormal "BRAF" gene.

Number of Participants with Adverse Events to determine Ph II dose
At each dose level, the number of patients experiencing Adverse Events over their course of treatment will be characterized by type of Adverse Event and grade using NCI CTCAE (v4.0), and by time of onset in relation to the first day of therapy.
Time frame: 12-24 months from study start
Progression Free and overall survival (Efficacy)
•Progression Free Survival will be evaluated at 6 months using the Kaplan-Meier method. Overall Survival will be measured from the initial date of treatment to the recorded date of death, and analyzed similarly to Progression Free Survival. Overall Survival will also be analyzed with the Kaplan-Meier method. The complete response rate and partial response rate will be estimated by the proportion of patients with a best response respectively by RECIST criteria.
Time frame: 48 months
