Primary Outcome Measures:
  • Incidence of Dose Limiting Toxicities (Phase Ib) [ Time Frame: Cycle 1 = 28 days ] [ Designated as safety issue: Yes ]
    Dose Limiting Toxicities (DLTs) during the first 28 days of the combination treatment of LEE011 and LGX818.

  • Progression Free Survival (PFS) - Phase II Arms 1 a/b [ Time Frame: 23 months after FPFV ] [ Designated as safety issue: No ]
    As per RECIST v1.1. PFS is the time from date of randomization/start of treatment to the date of event defined as the first documented progression or death due to any cause.

  • Objective Response Rate (ORR) - Phase II Arm 2 [ Time Frame: 23 months after FPFV ] [ Designated as safety issue: No ]
    As per RECIST v1.1. ORR is defined as the proportion of patients with a best overall response of complete response or partial response.


Secondary Outcome Measures:
  • Number of Adverse Events - Phase Ib/II [ Time Frame: Approximately 23 months after FPF ] [ Designated as safety issue: Yes ]
    To assess the safety and tolerability of LEE011 and LGX818 in these patients which includes changes in hematology and chemistry values, vital signs and elctrocardiograms (ECG's) assessed according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

  • Number of Serious Adverse Events - Phase Ib/II [ Time Frame: Approximately 23 months after FPFV ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Experimental: Phase Ib
Pahse Ib will randomize 18 patients with BRAF mutant melanoma, who are naive or who have progressed on prior therapy tyo evaluate the safety and tolerability of the combination of LEE011 and LGX818.
Drug: LEE011
LEE011 will be administered orally, once daily for 21 consecutive days followed by a 7-day planned break (28-day cycle).
Drug: LGX818
LGX818 will be administered orally, once daily on a continuous dosing schedule (28-day cycle).
Experimental: Phase II arm 1a
Phase II arm 1a will randomize 60 patients that are naïve to prior BRAF inhibitor therapy to LGX818+LEE011 to evaluate the effect of adding LEE011 to a BRAFi in this population.
Drug: LEE011
LEE011 will be administered orally, once daily for 21 consecutive days followed by a 7-day planned break (28-day cycle).
Drug: LGX818
LGX818 will be administered orally, once daily on a continuous dosing schedule (28-day cycle).
Experimental: Phase II arm 1b
Phase II arm 1b will randomize 30 patients to LGX818. Single agent anti-tumor activity of LGX818 is comparable to other BRAFi that are either approved or in clinical trials. This single agent anti-tumor activity will be compared to that of the combination (LEE011 + LGX818) in the BRAFi naïve patient population.
Drug: LGX818
LGX818 will be administered orally, once daily on a continuous dosing schedule (28-day cycle).
Experimental: Phase II arm 2
Phase II arm 2 will evaluate a single arm LEE011+LGX818 in 40 patients resistant to prior BRAF inhibitor therapy. Single agent LGX818 has shown limited activity in patients with melanoma who have failed prior BRAF inhibitor treatment; the contribution of LEE011 in this combination will be evaluated.
Drug: LEE011
LEE011 will be administered orally, once daily for 21 consecutive days followed by a 7-day planned break (28-day cycle).
Drug: LGX818
LGX818 will be administered orally, once daily on a continuous dosing schedule (28-day cycle).
