A Phase Ib/II Study of LGX818 in Combination With MEK162 in Adult Patients With BRAF Dependent Advanced Solid Tumors

This is a multi-center, open-label, dose finding, Phase Ib dose escalation study to estimate the MTD(s) and/or RP2D(s) for the dual combination of LGX818 and MEK162 and the triple combination of LGX818 and MEK162 and LEE011, followed each independently by a Phase II part to assess the clinical efficacy and to further assess the safety of the combinations in selected patient populations. Oral LGX818 and MEK162 will be administered on a continuous schedule. Oral LEE011 will be administered once daily on a three weeks on, one week off schedule. Patients will be treated until progression of disease, unacceptable toxicity develops, or withdrawal of informed consent, whichever occurs first. A cycle is defined as 28 days. The dose escalation parts of the trial will be conducted in adult patients with BRAF V600-dependent advanced solid tumors and is expected to enroll at least 18 patients for the dual combination and at least 12 patients for the triple combination. The dose escalation will be guided by a Bayesian logistic regression model (BLRM). Following MTD/RP2D declaration, patients will be enrolled in three Phase II arms for the dual combination and one Phase II arm for the triple combination. All patients will be followed for 30 days for safety assessments after study drugs discontinuation. All patients enrolled in the Phase II part of the study will be followed for survival.

Further study details as provided by Array BioPharma:

Primary Outcome Measures:
  • Phase Ib: Estimation of Maximum Tolerated Dose (MTD) by measuring incidence of dose limiting toxicities (DLT) [ Time Frame: up to 8 months ]
    To estimate the MTD(s) and/or recommended phase 2 dose(s) (RP2D(s)) of oral LGX818 in combination with oral MEK162, and of oral LGX818 in combination with oral MEK162 and oral LEE011 in patients with BRAF V600-dependent advanced solid tumors by measuring the incidence of DLTs as defined by the protocol.

  • Phase II: Clinical efficacy [ Time Frame: up to 14 months ]
    Assess clinical efficacy of the LGX818 and MEK162 dual combination and LGX818 and MEK162 and LEE011 triple combination in the Phase II populations by evaluating the disease control rate (DCR) and objective response rate (ORR) as per RECIST 1.1

Secondary Outcome Measures:
  • Safety and tolerability of LGX818 and MEK162 dual combination, and LGX818 and MEK162 and LEE011 triple combination by evaluating the incidence and severity of adverse events (AE). [ Time Frame: up to 17 months ]
    To characterize the safety and tolerability of LGX818 and MEK162 in combination, and LGX818 and MEK162 and LEE011 in combination by evaluating the incidence and severity (as per CTCAE grading) of AEs in all patients enrolled in the study.

  • Determination of single and multiple dose of Pharmacokinetics (PK) profile by measuring plasma concentrations versus time after study drug combination dosing (Phase Ib) [ Time Frame: up to 8 months ]
    To determine the single and multiple dose PK profile of the LGX818 and MEK162 combination and LGX818 and MEK162 and LEE011 combination, by measuring plasma concentrations of MEK162 and LGX818 and LEE011 resp. at different timepoints prior and post study drug combination dosing on several days within cycle 1 and subsequent cycles.

  • Preliminary clinical anti-tumor activity by evaluating the objective response rate (Phase Ib) [ Time Frame: up to 8 months ]
    To assess preliminary anti-tumor activity of the LGX818 and MEK162 combination, and the LGX818 and MEK162 and LEE011 combination by evaluating the ORR as per RECIST 1.1. Safety Issue?: (FDAAA) No

  • Further clinical efficacy (phase II) [ Time Frame: up to 14 months ]
    To further assess clinical efficacy of the LGX818 and MEK162 combination and the LGX818 and MEK162 and LEE011 combination in the Phase II populations by measuring progression free survival (PFS) as per RECIST 1.1
