Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Panitumumab + Irinotecan

Participants received panitumumab 6 mg/kg and irinotecan 180 mg/m² administered by intravenous (IV) infusion every 2 weeks until disease progression or intolerance of panitumumab, irinotecan or both.

Group Type EXPERIMENTAL

Panitumumab

Intervention Type DRUG

The first infusion of panitumumab will occur on Cycle 1 Day 4. On Cycle 2 Day 1, panitumumab will be administered on the same day as irinotecan and every 2 weeks thereafter.

Irinotecan

Intervention Type DRUG

The first infusion of irinotecan will occur on Cycle 1 Day 1. Irinotecan will be administered on the same day as panitumumab on Cycle 2 Day 1 and every 2 weeks thereafter.
