Summary:

      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.

             birth control during the study and for up to 4 weeks after the last dose of study
             medication.

          -  Men with reproductive potential must be willing to practice acceptable methods of
