What was measured

AUClast was defined as area under the plasma concentration time curve from time zero to the last measurable concentration. AUClast was calculated using linear/log trapezoidal method. The ratio between geometric LS mean (within Cohort 1) for AUClast on Cycle 1 Day 15 and geometric LS mean (within Cohort 1) for AUClast on Cycle 1 Day 1 for irinotecan and its metabolite SN-38 has been presented in this outcome measure, which explains the data reported for this outcome measure using measure type as "Number".

Analysis population: The PK parameter analysis set was analyzed. Here, "Overall Number of Participants Analyzed" signifies participants evaluable for this outcome measure. Participants received irinotecan in Cohort 1 of SLI, hence data is reported only for Cohort 1 and not for Cohort 2.

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.
