  Purpose

BRF113683 is a Phase III, randomized, open-label study comparing the efficacy, safety, and tolerability of GSK2118436 to dacarbazine (DTIC), in subjects with BRAF mutant advanced (Stage III) or metastatic (Stage IV) melanoma. Subjects will be randomized to receive 150 mg of GSK2118436 twice daily or 1000 mg/m2 DTIC every 3 weeks and continue on treatment until disease progression, death, or unacceptable adverse event. Subjects who progress on DTIC will be allowed to crossover to an optional extension arm of the study to receive GSK2118436.

Primary Outcome Measures:
  • Progression free survival (PFS), defined as the time from randomization until the first date of either objective disease progression or death due to any cause. [ Time Frame: approximately 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Overall survival (OS) defined as the time from randomization to death due to any cause [ Time Frame: approximately 2 years ] [ Designated as safety issue: No ]
  • PFS, defined for subjects randomized to the DTIC treatment groups as the time to progression or death after cross-over to GSK2118436 after initial progression on DTIC. [ Time Frame: approximately 2 years ] [ Designated as safety issue: No ]
  • Overall response rate (ORR), defined as the percentage of subjects achieving either a commplete or partial tumor response. [ Time Frame: approximately 2 years ] [ Designated as safety issue: No ]
  • Duration of response, defined for those subjects who show a complete or partial tumor response, the time from first documented complete response or partial response until the first documented sign of disease progression or death due to any cause. [ Time Frame: approximately 2 years ] [ Designated as safety issue: No ]
  • Duration of response in subjects who cross-over to GSK2118436, after initial progression on DTIC [ Time Frame: approximately 2 years ] [ Designated as safety issue: No ]
  • Rate of treatment-emergent non-melanoma skin lesions in each treatment group, defined as the percentage of subjects with non-melanoma skin lesions reported [ Time Frame: approximately 2 years ] [ Designated as safety issue: No ]
  • Validation of the BRAF mutation assay. [ Time Frame: approximately 2 years ] [ Designated as safety issue: No ]
