This is a multicenter, randomized, open-label, 3-arm Phase 3 study to evaluate encorafenib + cetuximab plus or minus binimetinib versus Investigator's choice of either irinotecan/cetuximab or FOLFIRI/cetuximab, as controls, in patients with BRAFV600E mCRC whose disease has progressed after 1 or 2 prior regimens in the metastatic setting. The study contains a Safety Lead-in Phase in which the safety and tolerability of encorafenib + binimetinib + cetuximab will be assessed prior to the Phase 3 portion of the study.

(Phase 3) Change From Baseline in the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire for Cancer Participants (QLQ-C30) Triplet Arm vs Control Arm, Doublet Arm vs Control, and Triplet vs Doublet
The EORTC QLQ-C30 questionnaire consisted of 30 questions generating 5 functional scores (physical, role, cognitive, emotional, \& social); a global health (GH) status/global quality of life scale score; 3 symptom scale scores (fatigue, pain, \& nausea \& vomiting); \& 6 standalone one-item scores that capture additional symptoms (dyspnea, appetite loss, sleep disturbance, constipation, \& diarrhea) \& perceived financial burden. All items were graded by severity experienced during previous week \& used 4-point-scale (1: not at all, 2: a little, 3: quite a bit, 4: very much). The scores were converted to health-related quality of life (HRQoL) scale ranging from 0-100. Higher scores indicating higher response levels (i.e., higher functioning, higher symptom severity).
Time frame: Baseline, Cycle(C)1 Day(D)1 , C2 D1, C3 D1, C4 D1, C5 D1, C6 D1, C7 D1, C8 D1, C9 D1, C10 D1, C11 D1, C12 D1, C13 D1, C14 D1, C15 D1, C16 D1, C17 D1, C18 D1, C19 D1, C20 D1, C21 D1, C22 D1, C23 D1, End of Treatment, 30 Day Follow Up(each cycle of 28 days)

It consists of total 36 items (27 items of general version of FACT-C and disease-specific subscale containing 9 CRC-specific items), summarized to 5 subscales: physical well-being (7 items), functional well-being (7 items), social/family well-being (7 items); all 3 subscales range:0-28, emotional well-being (6 items) range: 0-24, colorectal cancer subscale (9 items) range: 0-36; higher subscale score= better QoL. All single-item measures range: 0= 'Not at all' to 4= 'Very much'. Table summarizes functional well-being subscale, individual questions are linearly scaled \& combined to form functional well-being subscale score (range 0-28). High score represents better QoL.

(Phase 3) Change From Baseline in the EuroQol-5D-5L Visual Analog Scale (EQ-5D-5L VAS) in Triplet Arm vs Control Arm, Doublet Arm vs Control, and Triplet vs Doublet
The EQ-5D-5L contains 1 item for each of 5 dimensions of health-related QoL (i.e., mobility, self-care, usual activities, pain or discomfort and anxiety or depression). Response options for each item varied from having no problems to moderate problems or extreme problems. The EQ-5D-5L (v4.0) is a standardized measure of health utility that provides a single index value for one's health status. The EQ-5D-5L is frequently used for economic evaluations of health care and has been recognized as a valid and reliable instrument for this purpose. The EQ visual analog scale (VAS) is a score that is directly reported by the participant and ranges from 0 to 100 (higher is better quality health).
Time frame: Baseline,Cycle (C)1 Day (D)1, C2 D1, C3 D1, C4 D1, C5 D1, C6 D1, C7 D1, C8 D1, C9 D1, C10 D1, C11 D1, C12 D1, C13 D1, C14 D1, C15 D1, C16 D1, C17 D1, C18 D1, C19 D1, C20 D1, C21 D1, C22 D1, C23 D1, End of Treatment, 30 Day Follow Up(each cycle of 28 days)
(Phase 3) Change From Baseline in the Participant Global Impression of Change (PGIC) in Triplet Arm vs Control Arm, Doublet Arm vs Control, and Triplet vs Doublet

For this assessment, participants answered the following question: "Since starting treatment, my colorectal cancer symptoms are: (1) very much improved, (2) much improved, (3) minimally improved, (4) no change, (5) minimally worse, (6) much worse or (7) very much worse."

Newly occurring clinically notable changes was defined as participants not meeting the criterion at baseline and meeting criterion post-baseline. The criterion included: low/high systolic blood pressure (SBP): \<= 90 millimeters of mercury (mmHg) with decrease from baseline of \>= 20mmHg or \>= 160mmHg with increase from baseline of \>= 20mmHg, low or high diastolic blood pressure (DBP): \<= 50mmHg with decrease from baseline of \>= 15mmHg or \>= 100mmHg with increase from baseline of \>= 15mmHg, low or high pulse: \<= 50 beats/min with decrease from baseline of \>= 15 beats/min or \>= 120 beats/min with increase from baseline of \>= 15 beats/min, low or high temperature: \<= 36 degree Celsius (deg C) or \>= 37.5 deg C.

Phase 3: Number of Participants With Shift in Visual Acuity Logarithm of the Minimum Angle of Resolution (LogMAR) Score
Visual acuity was measured using the Snellen visual acuity conversion chart. This was determined by establishing the smallest optotypes that could be identified correctly by the participant at a given observation distance. Snellen visual acuity was reported as a Snellen fraction (m/M) in which the numerator (m) indicated the test distance and the denominator (M) indicated the distance at which the gap of the equivalent Landolt ring subtends 1 minute of arc. The LogMAR score was calculated as - log(m/M). The maximum increase in score of \<= 0, 0 to \< 0.1, 0.1 to \< 0.2, 0.2 to \< 0.3 and \>=0.3 relative to baseline in LogMAR were reported in this endpoint.
Time frame: From start of study treatment until 30 days post last dose of study treatment (for triplet arm: maximum treatment exposure of 277.4 weeks; for doublet arm: maximum treatment exposure of 268 weeks; for Control arm: maximum treatment exposure of 108 weeks)
Phase 3: Number of Participants With Shifts in Left Ventricular Ejection Fraction (LVEF) From Baseline to Maximum Grade On-treatment
Left ventricular ejection fraction (LVEF) abnormalities were defined according to CTCAE version 4.03 where Grade 0: Non-missing value below Grade 2, Grade 2: LVEF between 40% and 50% or absolute change from baseline between -10% and \< -20%, Grade 3: LVEF between 20% and 39% or absolute change from baseline \<= -20%, Grade 4: LVEF lower than 20%. Categories with at least 1 non-zero data values showing any shift in Grade from baseline to 1 day after dose 1 (post-baseline) were reported. Participants whose grade category was unchanged (e.g. Grade 0 to Grade 0) were not reported.
Time frame: From start of study treatment until 30 days post last dose of study treatment (for triplet arm: maximum treatment exposure of 277.4 weeks; for doublet arm: maximum treatment exposure of 268 weeks; for Control arm: maximum treatment exposure of 108 weeks)
