Intervention

Drug:
• Cetuximab
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.
• Oxaliplatin
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.
• Folinic Acid
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.
• 5Fluorouracil
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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression Free Survival (PFS) Time	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.	Baseline up to 333 weeks
Secondary	Overall Survival (OS) Time	OS was defined as the time (in months) from randomization to death. For subjects who were still alive at the analysis data cut-off date or who lost to follow-up, survival was censored at the last recorded date that the subject was known to be alive.	Baseline up to 333 weeks
Secondary	Best Overall Response Rate (ORR)	The Best ORR was defined as the percentage of subjects having achieved complete response (CR) or partial response (PR) according to RECIST version 1.0 as determined by the IRC. CR: defined as disappearance of all target and all non-target lesions and no new lesions. PR: defined as at least a 30% decrease in sum of diameters of target lesions, taking as reference the baseline sum diameters, no progression of non-target lesions and no new lesions.	Baseline up to 333 weeks
Secondary	Time to Treatment Failure (TTF)	TTF was defined as time from randomization to date of the first occurrence of radiologically confirmed PD as determined by IRC, Clinical PD according to the Investigator's assessment (if radiological confirmation of PD by IRC was unavailable), discontinuation of treatment due to progression or adverse event, start of new anticancer therapy, withdrawal of consent, or death within 90 days of last tumor assessment or randomization. Subjects without event were censored on the date of last tumor assessment.	Baseline up to 333 weeks
Secondary	Number of Subjects With Curative Surgery of Liver Metastases	The number of subjects who underwent liver metastatic surgery after start of treatment and the outcome of surgery with respect to residual tumor after surgery (R0, R1, R2, not evaluable) were summarized. In case of resection of more than one metastasis, the worst outcome of surgery defined the overall status of a subject. R0 = No residual tumor after resection (all lesions resected completely); R1 = Metastases not resected completely with microscopic residual lesions; and R2 = Metastases not resected completely with macroscopic residual lesions.	Baseline up to 333 weeks
