What was measured

TTR was defined as the time from the date of first dose to first radiographic evidence of response (CR or PR) per RECIST v1.1 by derived investigator assessment. CR: disappearance of all target lesions and non-target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR: \>= 30% decrease under baseline of the sum of diameters of all target measurable lesions.

Analysis population: The FAS for Cohort 3 included all participants who were randomized in the Cohort 3 portion of the study, respectively. Here, "Overall Number of Participants Analyzed" signifies participants evaluable for this outcome measure with a confirmed objective response by derived investigator assessment.

Groups in this outcome

Cohort 3: Arm D [EC + FOLFIRI]

Participants received encorafenib 300 mg QD orally and cetuximab 500 mg/m\^2 IV infusion for 120 minutes Q2W along with fluorouracil 400 mg/m\^2 IV bolus then 2400 mg/m\^2 continuous IV infusion over 46-48 hours Q2W; leucovorin 400 mg/m\^2 IV infusion for 120 minutes Q2W and irinotecan 180 mg/m\^2 as IV infusion for 90 minutes Q2W. Participants received treatment in 28-day cycles.

Cohort 3: Arm E [FOLFIRI With or Without Bevacizumab]

Participants received fluorouracil 400 mg/m\^2 IV bolus then 2400 mg/m\^2 continuous IV infusion over 46-48 hours Q2W; leucovorin 400 mg/m\^2 IV infusion for 120 minutes Q2W and irinotecan 180 mg/m\^2 as IV infusion for 90 minutes Q2W with or without bevacizumab. Bevacizumab was optional and it was given per prescribing instructions of treating physician. Participants received treatment in 28-day cycles.
