Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 553
Healthy volunteers: no

Brief summary:
The purpose of this study was to assess whether the progression free survival (PFS) time with FOLFOX-4 plus cetuximab is longer than that with FOLFOX-4 alone as first-line treatment for mCRC in Chinese subjects with RAS wild-type tumors.

Detailed description:

Arms:
arm 1: Subjects received cetuximab in combination with FOLFOX-4 chemotherapy regimen. FOLFOX-4 chemotherapy regimen consists of a combination of oxaliplatin with 5-fluorouracil (5-FU)/folinic acid (FA). Cetuximab was always administered every 7 days with an initial dose of 400 milligram per square meter (mg/m\^2) at 5 milligram per minute (mg/min) and 250 mg/m\^2 at 10 mg/min for subsequent infusions, followed by oxaliplatin 85 mg/m\^2 infused over 120 minutes at least 1 hour later. Following completion of the oxaliplatin infusion or simultaneously with oxaliplatin, FA was administered at a dose of 200 mg/m\^2 infused over 120 minutes, on Day 1, Day 2, and every 2 weeks and then 5- FU was administered as a bolus of 400 mg/m\^2/day intravenously over 2-4 minutes followed by 600 mg/m\^2/day infused over 22 hours, on Day 1, Day 2, and every 2 weeks. All subjects received treatment until progression of disease, withdrawal of consent, or unacceptable toxicity. arm 2: Subjects received FOLFOX-4 chemotherapy regimen that consists of a combination of oxaliplatin with 5-FU/FA. Oxaliplatin 85 mg/m\^2 infused over 120 minutes was administered first or simultaneously with FA at a dose of 200 mg/m\^2 infused over 120 minutes on Day 1, Day 2, and every 2 weeks and then 5-FU was administered as a bolus of 400 mg/m\^2/day intravenously over 2-4 minutes followed by 600 mg/m\^2/day infused over 22 hours on Day 1, Day 2, and every 2 weeks. All subjects received treatment until progression of disease, withdrawal of consent, or unacceptable toxicity.

Intervention descriptions: intervention 1: Cetuximab was administered every 7 days at an initial dose of 400 milligram per square meter (mg/m\^2) at 5 milligram per minute (mg/min) and 250 mg/m\^2 at 10 mg/min for subsequent infusions until progression of disease, withdrawal of consent, or unacceptable toxicity to cetuximab. intervention 2: Oxaliplatin 85 mg/m\^2 infusion over 120 minutes on Day 1, Day 2, and then every 2 weeks until progression of disease, withdrawal of consent, or unacceptable toxicity. intervention 3: FA 200 mg/m\^2 infusion over 120 minutes on Day 1, Day 2, and then every 2 weeks until progression of disease, withdrawal of consent, or unacceptable toxicity. intervention 4: 5-FU as a bolus of 400 mg/m\^2/day intravenously over 2-4 minutes followed by 600 mg/m\^2/day infusion over 22 hours on Day 1, Day 2, and then every 2 weeks until progression of disease, withdrawal of consent, or unacceptable toxicity.
