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.
Name: Encorafenib
Name: Binimetinib

Name: Folinic Acid
Name: 5-Fluorouracil
Description: Refer to AE/SAE section for additional data that were measured and analyzed.
Measure: (Safety Lead-in) Number of Participants With Adverse Events (AEs) Time: Duration of safety lead-in, approximately 6 months (up to 28 days per cycle)Description: ORR per RECIST, v1.1, defined as the number of patients achieving an overall best response of CR or partial response (PR) divided by the total number of patients
Measure: (Safety Lead-in) Response Rate (ORR) by BICR Time: Duration of safety lead-in, approximately 6 months (up to 28 days per cycle)Description: DOR defined as the time from first radiographic evidence of response to the earliest documented disease progression or death due to underlying disease
Measure: (Safety Lead-in) Duration of Response (DOR) by BICR Time: Duration of safety lead-in, approximately 6 months (up to 28 days per cycle)Description: Time to response defined as the time from first dose to first radiographic evidence of response
Measure: (Safety Lead-in) Time to Response by Investigator Time: Duration of safety lead-in, approximately 6 months (up to 28 days per cycle)Description: Time to response defined as the time from first dose to first radiographic evidence of response
Measure: (Safety Lead-in) Time to Response by BICR Time: Duration of safety lead-in, approximately 6 months (up to 28 days per cycle)Description: PFS defined as the time from first dose to the earliest documented disease progression or death due to any cause
Measure: (Safety Lead-in) Progression-free Survival (PFS) by BICR Time: Duration of safety lead-in, approximately 6 months (up to 28 days per cycle)Description: The EORTC QLQ-C30 questionnaire consisted of 30 questions generating five functional scores (physical, role, cognitive, emotional, and social); a global health status/global quality of life scale score; three symptom scale scores (fatigue, pain, and nausea and vomiting); and six stand alone one-item scores that capture additional symptoms (dyspnea, appetite loss, sleep disturbance, constipation, and diarrhea) and perceived financial burden. All the scales and single-item scores were linearly transformed so that each score ranged from 0 to 100. A higher score on the global health and functioning subscales is indicative of better functioning.
Measure: (Phase 3) Change From Baseline in the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire for Cancer Patients (QLQ-C30) Triplet Arm vs Control Arm, Doublet Arm vs Control, and Triplet vs Doublet Time: Duration of Phase 3, approximately 6 months (up to 28 days per cycle)Description: FACT-C is a well-characterized and commonly used questionnaire that belongs to the Functional Assessment of Chronic Illness Therapy Measurement System (FACIT). The FACT-G (G for general) questionnaire (27 questions) constitutes the core of all subscales and is applicable to all tumor types. The FACT-C questionnaire contains 9 additional questions on symptoms specific to CRC, 2 of which are only answered by patients with ostomy appliances. These 9 CRC-specific questions are categorized as "additional concerns" on the questionnaire and constitute the "colorectal cancer subscale" score. The patient self-reports his/her QoL for the previous 7 days. The overall score is calculated across all items and a higher score reflects better quality of life (QoL). The table summarizes the functional well-being subscale, the individual questions are linearly scaled and combined to form the functional well-being subscale score, which ranges from 0-28 (higher is better QoL).
Measure: (Phase 3) Change From Baseline in the Functional Assessment of Cancer Therapy-Colon Cancer (FACT-C) in Triplet Arm vs Control Arm, Doublet Arm vs Control, and Triplet vs Doublet Time: Duration of Phase 3, approximately 6 months (up to 28 days per cycle)Description: 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 patient and ranges from 0 to 100 (higher is better quality health).
Measure: (Phase 3) Change From Baseline in the EuroQol-5D-5L (EQ-5D-5L) in Triplet Arm vs Control Arm, Doublet Arm vs Control, and Triplet vs Doublet Time: Duration of Phase 3, approximately 6 months (up to 28 days per cycle)Description: The PGIC is a measure of patients' perceptions of change in their symptoms over time that can be used as an anchoring method to determine the minimal clinically important difference for other patient reported outcome (PROs). For this assessment, patients 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."
Measure: (Phase 3) Change From Baseline in the Patient Global Impression of Change (PGIC) in Triplet Arm vs Control Arm, Doublet Arm vs Control, and Triplet vs Doublet Time: Duration of Phase 3, approximately 6 months (up to 28 days per cycle)Description: The cross-arm CL/F value is based on the theta determined from a population PK analysis.
