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.

  1. description
    PFS is defined as the interval of time between the date of randomization and the earlier of the date of disease progression or the date of death due to any cause. Disease progression was based on radiographic or photographic evidence, and assessments were made by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. PD is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as a reference, the smallest sum of diameters recorded since the treatment started (e.g., percent change from nadir, where nadir is defined as the smallest sum of diameters recorded since treatment start). In addition, the sum must have an absolute increase from nadir of 5 millimeters (mm). For participants who did not progress or die, PFS was censored at the date of last contact. Data are presented as median and 96% confidence interval.

Any pathological lymph nodes must be \<10 mm in the short axis.) or PR (at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the Baseline sum of the diameters \[e.g., percent change from Baseline\]). Response was evaluated by an investigator per RECIST, version 1.1. A participant without a post-Baseline assessment of response was considered a non-responder. Confirmation, per RECIST version 1.1, requires a confimatory disease assessment of CR or PR at least 28 days after the initial disease assessment of CR or PR.
