Trial Description


This is a two-arm, open-label, randomised, Phase III study comparing dabrafenib (GSK2118436) and trametinib (GSK1120212) combination therapy to vemurafenib. Subjects with histologically confirmed cutaneous melanoma that is either stage IIIc (unresectable) or stage IV, and BRAF V600E/K mutation positive will be screened for eligibility. Subjects who have had prior systemic anti-cancer treatment in the advanced or metastatic setting will not be eligible although prior systemic treatment in the adjuvant setting will be allowed. Approximately 694 subjects will be randomised 1:1 (combination therapy:vemurafenib). The primary endpoint is overall survival (OS) for subjects receiving the combination therapy compared with those receiving vemurafenib.

Eligibility Criteria

Inclusion Criteria:

  • >= 18 years of age
  • Stage IIIc or Stage IV BRAF V600E/K cutaneous melanoma
  • Measurable disease according to RECIST 1.1
  • Women of childbearing potential with negative serum pregnancy test prior to randomisation
  • Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
  • Adequate baseline organ function

Exclusion Criteria:

  • Any prior use of a BRAF or MEK inhibitor
  • Prior systemic anti-cancer treatment in the advanced or metastatic setting; prior systemic treatment in the adjuvant setting is allowed
  • History of another malignancy (except subjects who have been disease free for 3 years or with a history of completely resected non-melanoma skin cancer)
  • Known HIV, HBV, HCV infection (except chronic or cleared HBV and HCV infection which will be allowed)
  • Brain metastases (except if all known lesions were previously treated with surgery or stereotactic radiosurgery and lesions, if still present, are confirmed stable for >= 12 weeks prior to randomisation or if no longer present are confirmed no evidence of disease for >= 12 weeks, and are asymptomatic with no corticosteroid requirements for >= 4 weeks prior to randomisation, and no enzyme inducing anticonvulsants for >= 4 weeks prior to randomisation
  • History or evidence of cardiovascular risk (LVEF < LLN; QTcB >= 480 msec; blood pressure or systolic >=140 mmHg or diastolic >= 90 mmHg which cannot be controlled by anti-hypertensive therapy)
  • History or current evidence/risk of retinal vein occlusion (RVO) or central serous retinopathy (CSR)
