Treatment and study plan

FOLFOX-4

Drug

The FOLFOX-4 regimen will be administered every 2 weeks as follows:

Day 1: oxaliplatin (ELOXATIN™) 85 mg/m2 IV infusion and leucovorin racemate 200 mg/m2 (or 100 mg/m2 l-LV) IV infusion given over 120 ± 10 minutes at the same time in separate bags using a Y-line, followed by 5-FU 400 mg/m2 IV bolus given over 2 to 4 minutes, followed by 5-FU 600 mg/m2 IV infusion as a 22-hour ± 2 hours continuous infusion Day 2: leucovorin racemate 200 mg/m2 (or 100 mg/m2 l-LV) IV infusion over 120 ± 10 minutes, followed by 5-FU 400 mg/m2 IV bolus given over 2 to 4 minutes, followed

AMG 706

Drug

AMG 706 is a small organic molecule that has been shown in preclinical pharmacology studies to be a potent, oral, multi-kinase inhibitor with anti-angiogenic and anti-tumor activity achieved by selectively inhibiting all known VEGF receptors, PDGF receptor, and Kit.

Panitumumab (Part 1a only)

Biological

Panitumumab will be administered by IV infusion at a dose of 6 mg/kg on day 1 of each 2-week cycle.

FOLFIRI

Drug

Irinotecan will be administered over 90 minutes ± 15 minutes on day 1 of each 2-week cycle. Leucovorin will be administered over 2 hours ± 15 minutes during the irinotecan infusion but without mixing, immediately followed by a 5-FU bolus and a 5-FU 46-hour ± 2-hour continuous intravenous infusion.
