Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the efficacy and safety of two different schedules of administration of vemurafenib in combination with cobimetinib (continuous and intermittent) in previously untreated BRAFV600- mutation positive patients with unresectable locally advanced or metastatic melanoma.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

A - Continuous Administration

960 mg of vemurafenib po, bid, days 1 to 28 and 60 mg of cobimetinib po, od, days 1 to 21, for each 28-days' cycle.

Group Type EXPERIMENTAL

Intervention Type DRUG

Comparison between different treatment regimens

B - Intermittent Administration

960 mg of vemurafenib po, bid, days 1 to 28 and 60 mg of cobimetinib po, od, days 1 to 21, for each 28-days' cycle, during 12 weeks. After that period, patients will be treated with both drugs at the same doses indicated previously, but with an intermittent pattern: vemurafenib days 1 to 28 followed by 14 days off (4 weeks on and 2 weeks off) and cobimetinib days 1 to 21 followed by 21 days off (3 weeks on and 3 weeks off)

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

History of isolated elevation in prostate-specific antigen in the absence of radiographic evidence of metastatic prostate cancer is allowed.

If not automated, calculation of QTcF must be done through the following formula: QTcF = (QT interval in ms) / \[(60 / heart rate in bpm) )\^(1/3)\]

* Left ventricular ejection fraction (LVEF) below institutional lower limit of normal (LLN) or below 50%.

* All known CNS lesions have been treated with stereotactic therapy or surgery, AND
* There has been no evidence of clinical and radiographic disease progression in the CNS for major or equal 3 weeks after radiotherapy or surgery.

8. Current severe, uncontrolled systemic disease.
9. History of malabsorption or other condition that would interfere with absorption of study drugs.
10. Pregnant or lactating.
11. Unwillingness or inability to comply with study and follow- up procedures.
