This open-label, randomized, multicenter Phase II study will evaluate the safety and efficacy of MEHD7945A when combined with FOLFIRI chemotherapy as compared to cetuximab plus FOLFIRI in patients with KRAS wild-type metastatic colorectal cancer who have progressed after first-line oxaliplatin-containing chemotherapy for metastatic disease. Patients will be randomized to receive FOLFIRI chemotherapy plus either MEHD7945A (1100 mg intravenously every 2 weeks) or cetuximab (400mg/m2 iv loading dose Day 1 Cycle 1, followed by 250 mg/m2 iv every week). Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.
