Title: A Phase III, Double-Blind, Placebo-Controlled Study of Vemurafenib Versus Vemurafenib Plus GDC-0973 in Previously Untreated BRAF^600-Mutation Positive Patients With Unresectable Locally Advanced or Metastatic Melanoma
Brief Summary: To evaluate the efficacy of vemurafenib in combination with cobimetinib (GDC-0973), compared with vemurafenib and placebo, in previously untreated BRAF V600 mutation-positive patients with unresectable locally advanced or metastatic melanoma, as measured by progression-free survival (PFS), assessed by the study site investigator.

* Completely resected Stage III melanoma
* Tumor tissue available for evaluation of PD-L1 expression
* Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
* Adequate organ function
* No prior therapy for melanoma except surgery for primary melanoma lesions (or previously treated with interferon for thick primary melanomas without evidence of lymph node involvement are eligible)

* Male participants should agree to use an adequate method of birth control starting with the first dose of study therapy through 120 days after the last dose of study medication

Exclusion criteria:

* Mucosal or ocular melanoma
* History of (non-infectious) pneumonitis that required steroids or current pneumonitis

* Participant is or has an immediate family member (e.g., spouse, parent/legal guardian, sibling or child) who is investigational site or Sponsor staff directly involved with this trial without prospective Institutional Review Board approval (by chair or designee) is given
B: Inclusion Criteria:

* adults, \>/=18 years of age
* metastatic melanoma, stage IIIC or IV (AJCC)
* treatment-naïve (no prior systemic anticancer therapy)
* positive for BRAF V600E mutation
* measurable disease by RECIST criteria
* negative pregnancy test and, for fertile men and women, effective contraception during treatment and for 6 months after completion

Exclusion Criteria:

* active central nervous system metastases

* previous malignancy within 5 years prior to study, except for basal or squamous cell carcinoma of the skin, melanoma in-situ, or carcinoma in-situ of the cervix
C: Inclusion Criteria:

* At least 15 years of age Except: where local regulations and/or institutional policies do not allow for subjects \< 18 years of age (pediatric population) to participate. For those sites, the eligible subject population is ≥ 18 years of age
* Completely removed melanoma by surgery performed within 12 weeks of randomization
* Stage IIIb/C or Stage IV before complete resection

Other protocol-defined inclusion/exclusion criteria apply
D: Inclusion Criteria:

* Participants with histologically confirmed melanoma, either unresectable stage IIIc or stage IV metastatic melanoma, as defined by the American Joint Committee on Cancer 7th edition. Unresectability of stage IIIc disease must have confirmation from a surgical oncologist
* Participants must be naïve to treatment for locally advanced unresectable or metastatic disease (ie, no prior systemic anti-cancer therapy for advanced disease; stage IIIc and IV). Prior adjuvant immunotherapy (including ipilimumab) is allowed
* Documentation of BRAF V600 mutation-positive status in melanoma tumor tissue (archival or newly obtained tumor samples) using the cobas 4800 BRAF V600 mutation test
* Measurable disease per RECIST v1.1
* Eastern Clinical Oncology Group performance status of 0 or 1
* Consent to provide archival for biomarker analyses

* Palliative radiotherapy within 14 days prior to the first dose of study treatment
* Major surgery or traumatic injury within 14 days prior to first dose of study treatment
* Active malignancy other than melanoma that could potentially interfere with the interpretation of efficacy measures. Participants with a previous malignancy within the past 3 years are excluded except for participants with resected basal cell carcinoma or squamous cell carcinoma of the skin, melanoma in-situ, carcinoma in-situ of the cervix, and carcinoma in-situ of the breast
* History of or evidence of retinal pathology on ophthalmological examination that is considered a risk factor for neurosensory retinal detachment, retinal vein occlusion, or neovascular macular degeneration
* Uncontrolled glaucoma with intraocular pressure
* Serum cholesterol ≥ Grade 2
* Hypertriglyceridemia ≥ Grade 2
* Hyperglycemia (fasting) ≥ Grade 2
* History of clinically significant cardiac dysfunction
* Participants with active central nervous system (CNS) lesions (including carcinomatous meningitis) are excluded. However, participants are eligible if:

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