Condition or disease Intervention/treatment Phase
Advanced BRAF Mutant Cancers Drug: Binimetinib Drug: Encorafenib Phase 1 Phase 2

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 38 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: This phase I/II study consists of a Phase I part followed by an efficacy analysis (Phase II) of the dosing schedule deemed safe in patients with advanced cancer with activating non-V600 BRAF mutant tumors. As patients in the phase I part of the start will start at the lower dose level 1, they will not be included in the stage one efficacy cohort.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I/II Study of Binimetinib With Encorafenib in Patients With Non-V600 Activating BRAF Mutant Advanced Malignancies
Actual Study Start Date : February 14, 2019
Estimated Primary Completion Date : February 2023
Estimated Study Completion Date : February 2023

Arm Intervention/treatment
Experimental: Binimetinib and Encorafenib
Patients will be initially enrolled to the approved dose of encorafenib 450 mg oral QD and binimetinib 45 mg PO BID, dose level 1. If confirmed this dose level is safely tolerated in the study population, we will then escalate treatment to dose level 2 with the novel dosing regimen of encorafenib 450 mg oral QD continuous and binimetinib 60 mg oral BID 21 days on/7 days off.
Drug: Binimetinib
Dose level 1 binimetinib 45 mg PO BID. Dose level 2 binimetinib 60 mg oral BID
Other Name: MEK162 or ARRY-438162

Drug: Encorafenib
encorafenib 450 mg oral QD
Other Name: LGX818

Primary Outcome Measures :
  1. dose-limiting toxicities (DLTs) [ Time Frame: 1 year ]
    National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), Version 5,

  2. objective response rate (Phase II) [ Time Frame: 1 year ]
    Per RECIST Version 1.1
