简要总结
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.

研究组 & 干预措施
Cetuximab + FOLFOX-4
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.

结局指标
主要结局
Progression Free Survival (PFS) Time
时间窗: Baseline up to 333 weeks
PFS was defined as the duration (in months) from randomization until the first progressive disease (PD) observation as assessed by the Independent Review Committee (IRC) according to Response Evaluation Criteria for Solid Tumors (RECIST) version 1.0, or death due to any cause when death occurred within 90 days of randomization or the last tumor assessment, whichever was later. PD was defined as at least a 20% increase in the sum of longest diameter (LD) of the target lesions, taking as references the smallest sum LD since the treatment started (including baseline), or appearance of one or more new lesions, and/or unequivocal progression of existing non-target lesions.

- Overall Survival (OS) Time(Baseline up to 333 weeks)
