Arms Assigned Interventions
Experimental: Panitumumab Plus mFOLFOX6
Participants received 6 mg/kg panitumumab administered by intravenous (IV) infusion and modified FOLFOX6 (mFOLFOX6) chemotherapy regimen consisting of oxaliplatin (85 mg/m^2), leucovorin (400 mg/m^2) and 5-fluorouracil (5-FU) (2400 mg/m^2) administered on Day 1 of every 14-day cycle until disease progression, unacceptable toxicity, withdrawal of consent, or death.
Drug: Panitumumab
Panitumumab is a fully human immunoglobulin G (IgG)2 monoclonal antibody antagonist directed against human Epidermal Growth Factor receptor (EGFr).
Other Name: Vectibix
Drug: mFOLFOX6
mFOLFOX6 regimen is a combination therapy of oxaliplatin (85 mg/m^2) administered as a 2-hour infusion on Day 1; leucovorin (400 mg/m^2) administered as a 2-hour infusion on Day 1; followed by a loading dose of 5-fluorouracil (5-FU; 400 mg/m^2) IV bolus administered over approximately 2 to 4 minutes on Day 1, then 5- FU (2400 mg/m^2) via ambulatory pump administered for a period of 46 to 48 hours.
Active Comparator: Bevacizumab Plus mFOLFOX6
Participants received 5 mg/kg bevacizumab administered by IV infusion and the mFOLFOX6 regimen consisting of oxaliplatin (85 mg/m^2), leucovorin (400 mg/m^2), followed by 5-FU (2400 mg/m^2) administered on Day 1 of every 14-day cycle until disease progression, unacceptable toxicity, withdrawal of consent, or death.
Drug: Bevacizumab
Bevacizumab is a humanized monoclonal IgG1 antibody that is directed against Vascular Endothelial Growth Factor (VEGF).
Other Name: Avastin
Drug: mFOLFOX6
mFOLFOX6 regimen is a combination therapy of oxaliplatin (85 mg/m^2) administered as a 2-hour infusion on Day 1; leucovorin (400 mg/m^2) administered as a 2-hour infusion on Day 1; followed by a loading dose of 5-fluorouracil (5-FU; 400 mg/m^2) IV bolus administered over approximately 2 to 4 minutes on Day 1, then 5- FU (2400 mg/m^2) via ambulatory pump administered for a period of 46 to 48 hours.
