Trial Description

Summary

This multicenter, randomized, double-blind, placebo-controlled phase 3 study wil l evaluate the safety and efficacy of vemurafenib alone and vemurafenib in combi nation with GDC-0973 (cobimetinib), a MEK inhibitor, in previously untreated BRA F V600 mutation-positive patients with unresectable locally advanced or metastat ic melanoma. Patients will be randomized to one of two treatment arms, Arm A: ve murafenib 960 mg twice a day (days 1-28 of each cycle) and placebo (days 1-21 of each cycle); Arm B: vemurafenib 960 mg twice a day (days 1-28 of each cycle) an d GDC-0973 (cobimetinib) 60 mg once daily (days 1-21 of each cycle). Patients wi ll receive treatment until disease progression, unacceptable toxicity or withdra wal of consent.

Eligibility Criteria

Inclusion Criteria:

  • Patients 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.
  • Patients must be naïve to treatment for locally advanced unresectable or metastatic disease (i.e., no prior systemic anti-cancer therapy for advanced disease; stage IIIc and IV). Prior adjuvant immunotherapy (including ipilimumab) is allowed.
  • Documentation of BRAFV600 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.
  • Consent to undergo tumor biopsies for biomarker analyses.
  • Life expectancy >/= 12 weeks.
  • Adequate hematologic and end organ function

Exclusion Criteria:

  • History of prior RAF or MEK pathway inhibitor treatment.
  • 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. Patients with a previous malignancy within the past 3 years are excluded except for patients with resected basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) 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 ophthalmologic examination that is considered a risk factor for neurosensory retinal detachment, retinal vein occlusion (RVO), or neovascular macular degeneration.
  • Uncontrolled glaucoma with intra-ocular pressures
  • Serum cholesterol >/= Grade 2
  • Hypertriglyceridemia >/= Grade 2
  • Hyperglycemia (fasting) >/= Grade 2
  • History of clinically significant cardiac dysfunction
  • Patients with active CNS lesions (including carcinomatous meningitis) are excluded. However, patients 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

  • Current severe, uncontrolled systemic disease.
  • History of malabsorption or other condition that would interfere with absorption of study drugs.
  • Pregnant, lactating, or breast feeding.
