A 2-part Phase III Randomized, Open Label, Multicenter Study of LGX818 Plus MEK162 Versus Vemurafenib and LGX818 Monotherapy in Patients With Unresectable or Metastatic BRAF V600 Mutant Melanoma

This is 2-part, randomized, open label, multi-center, parallel group, phase III study
comparing the efficacy and safety of LGX818 plus MEK162 to vemurafenib and LGX818 monotherapy
in patients with locally advanced unresectable or metastatic melanoma with BRAF V600
mutation. A total of approximately 900 patients will be randomized.

Part 1:

Patients will be randomized in a 1:1:1 ratio to one of 3 treatment arms:

1. LGX818 450 mg QD plus MEK162 45 mg BID (denoted as Combo 450 arm)

2. LGX818 300 mg QD monotherapy (denoted as LGX818 arm) or

3. vemurafenib 960 mg BID (denoted as vemurafenib arm)

Part 2:

Patients will be randomized in a 3:1 ratio to one of the 2 treatment arms:

1. LGX818 300 mg QD plus MEK162 45 mg BID (denoted as Combo 300 arm) or

2. LGX818 300 mg QD monotherapy (denoted as LGX818 arm)


Inclusion Criteria:

- Diagnosis of locally advanced, unresectable or metastatic cutaneous melanoma or
unknown primary melanoma (AJCC Stage IIIB, IIIC, or IV)

- Presence of BRAF V600E or V600K mutation in tumor tissue prior to randomization

- Naïve untreated patients or patients who have progressed on or after prior first line
immunotherapy for resectable locally advanced or metastatic melanoma; prior adjuvant

than one line of immunotherapy for locally advanced unresectable or metastatic
melanoma; Ipilimumab (adjuvant) or other immunotherapy treatment must have ended at
least 6 weeks prior to randomization

- History of Gilbert's syndrome

- Prior therapy with a BRAF inhibitor and/or a MEK- inhibitor

- Impaired cardiovascular function or clinically significant cardiovascular diseases
