Subjects having received one prior regimen of chemotherapy must have had documented disease progression prior to randomization.
Prior treatment with immunotherapy (with the exception of prior ipilimumab, which is only allowed if given in the adjuvant setting), cytokine therapy, biological or vaccine regimen is permitted. Prior use of sorafenib is allowed. Disease progression must be documented for any anti-cancer therapy (i.e., immunotherapy or biologic therapy), if given as a most recent treatment prior to randomization.

Primary Outcome(s)

Secondary Objective: Secondary efficacy objectives:
• characterize PFS in subgroup of subjects from primary population (subjects with BRAF V600E mutation-positive melanoma without prior history of brain metastases) that have received no prior chemotherapy in the advanced or metastatic setting and the subgroup who have received one prior chemotherapy in the advanced or metastatic setting;
• further characterize efficacy in the primary population
• further characterize efficacy in the overall study population
• To characterize ORR and duration of response in subjects with BRAF V600 K mutation-positive melanoma regardless of prior history of brain metastases or prior chemotherapy;
• To characterize ORR and duration of response in subjects with BRAF V600E mutation-positive melanoma regardless of prior history of brain metastases or prior chemotherapy; and
• To characterize efficacy (PFS, ORR, and duration of response) in subjects following crossover from chemotherapy to TRAMETINIB.

Main Objective: The primary objective for this study is to establish the superiority of GSK1120212 over chemotherapy with respect to progression-free survival for subjects with advanced/metastatic BRAF V600E mutation-positive melanoma without a history of prior brain metastases.

Primary end point(s): The primary endpoint of this study will be progression free survival in subjects with BRAF V600E mutation positive melanoma without a prior history of brain metastases and will be based on investigator assessments. PFS is defined as the time from randomization until the earliest date of disease progression or death due to any cause.

Timepoint(s) of evaluation of this end point: Week 6, Week 12, Week 21 and Week 30 and then every 12 weeks ( ± 7 days)

Secondary Outcome(s)

Secondary end point(s): Overall survival defined as the time from randomization until death due to any cause, evaluated in the primary population (i.e. subjects with BRAF V600E mutation positive melanoma without a prior history of brain metastases). Overall survival will also be evaluated in the overall study population (i.e. regardless of BRAF mutation, prior history of brain metastases, or prior chemotherapy).
Best overall response defined as the percentage of subjects with evidence of CR or PR RECIST 1.1 [Eisenhauer, 2009], evaluated in all subjects, V600E subjects, V600K subjects, as well as the primary population of subjects with BRAF V600E mutation positive melanoma without a prior history of brain metastases. Response rate following crossover to GSK1120212 will also be evaluated.
Per RECIST 1.1 best overall response will be based on confirmed or unconfirmed responses as OS/PFS are the primary endpoints.

Duration of Response
For subjects who demonstrate CR or PR, duration of response is defined to be the time from first documented evidence of CR or PR until disease progression or death due to any cause. Duration of response for subjects who have not progressed or died at the time of analysis will be censored at the date of their last tumor assessment. Duration of Response will be evaluated in the primary population (i.e. subjects with BRAF V600E mutation positive melanoma without a prior history of brain metastases), all subjects regardless of BRAF mutation or history of brain metastases, V600E subjects, and V600K subjects.
Duration of response following crossover to GSK1120212 will also be evaluated.


PFS will be evaluated in the subset of subjects from the primary population (i.e. subjects with BRAF V600E mutation-positive melanoma without a prior history of brain metastases) without prior chemotherapy in the advanced or metastatic setting as well as the subgroup with prior chemotherapy in the advanced or metastatic setting.
Additionally PFS will be evaluated in all subjects regardless of BRAF mutation or prior history of brain metastases.

Timepoint(s) of evaluation of this end point: approx every 6-weeks
