What was measured

DLT: Any AE/lab value during first 28 days (D) of treatment that met at least 1 criteria: AE/lab value unrelated to underlying disease,PD,intercurrent illness,concomitant medications resulting in inability to tolerate atleast 75% of planned dose intensity of study drug,fatigue grade (G)3\>14 consecutive D, interstitial lung disease G\>=2,rash,hand foot skin reaction G3\>14 consecutive D or G4,diarrhea G3 \>=48 hours or G4,nausea/vomiting G3\>=48 hours or G4,mucositis G\>=3,total bilirubin G\>=3, aspartate aminotransferase/alanine aminotransferase G\>=3 in conjunction with total bilirubin G\>=2 or G3 \>7 consecutive D or G4,Serum creatinine G\>=3,absolute neutrophil count G4 \>7 consecutive D, \>=G3 febrile neutropenia,G3 platelet count decreased with signs of bleeding,platelet count G4,ECG QTcF prolonged \>=G3,G\>=3 uveitis \>21 consecutive D,G4 confirmed by ophthalmic examination,paresthesia/dysesthesias G\>=3,other G\>=3 hematologic/nonhematologic toxicity except lymphocyte count decreased G\>=3.

Analysis population: DLT evaluable analysis set included all participants who received at least 1 dose of study drug in the safety lead-in (SLI) and either experienced DLT during the DLT evaluation period or completed the DLT evaluation period without DLT.

Groups in this outcome

SLI: Cohort 1 [EC + FOLFIRI]

Participants received encorafenib 300 milligrams (mg) once daily (QD) orally (received after Cycle 1 Day 3) and cetuximab 500 mg per square meters (mg/m\^2) intravenous (IV) infusion for 120 minutes once every 2 weeks (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.

SLI: Cohort 2 [EC + mFOLFOX6]

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 oxaliplatin 85 mg/m\^2 IV infusion for 120 minutes Q2W. Participants received treatment in 28-day cycles.
