Arms Assigned Interventions
Experimental: Arm 1
Panitumumab plus mFOLFOX 6
Drug: Panitumumab
Panitumumab is a fully human IgG2 monoclonal antibody antagonist directed against human Epidermal Growth Factor receptor (EGFr).
Other Name: Vectibix
Drug: mFOLFOX6
Oxaliplatin, Leucovorin, 5-FU IV Bolus, 5-FU IV Infusion
Active Comparator: Arm 2
Bevacizumab plus mFOLFOX 6
Drug: Bevacizumab
Bevacizumab is a humanized monoclonal IgG1 antibody that is directed against Vascular Endothelial Growth Factor (VEGF). Bevacizumab, in combination with intravenous 5-fluorouracil-based chemotherapy, is indicated for first- or second-line treatment of patients with metastatic carcinoma of the colon or rectum.
Other Name: Avastin
Drug: mFOLFOX6
Oxaliplatin, Leucovorin, 5-FU IV Bolus, 5-FU IV Infusion
