A Phase III Randomized, 3-arm, Open Label, Multicenter Study of LGX818 Plus MEK162 and LGX818 Monotherapy Compared With Vemurafenib in Patients With Unresectable or Metastatic BRAF V600 Mutant Melanoma


Rochester, Minn.

Open for Enrollment
Why is this study being done?

A prospective, randomized, open label, multi-center, parallel group, 3-arm phase III study comparing the efficacy and safety of both, LGX818 plus MEK162 and LGX818 monotherapy, as compared to vemurafenib in patients with locally advanced unresectable or metastatic melanoma with BRAF V600 mutation. A total of approximately 900 patients will be randomized 1:1:1 to one of 3 treatment arms: 1) LGX818 plus MEK162 (denoted as Combination arm), 2) LGX818 monotherapy (denoted as LGX818 arm), 3) vemurafenib.
