Resumen

This is an exploratory study to compare activity and safety in 400 patients with previously untreated metastatic carcinoma of the colon treated with UFOX (a combination regimen of UFT® (Tegafur plus Uracil), Oxaliplatin, Folinic Acid) plus Cetuximab or FOLFOX-4 (a combination regimen of 5 Fluorouracil (5-FU), Oxaliplatin and Folinic Acid) plus Cetuximab)

Normal serum creatinine (in case of elevated creatinine, labelled ethylenediaminetetraacetic acid clearance ≥ 65 mL/min is acceptable)
Effective contraception for both male and female subjects if the risk of conception exists
Tumor biopsy or archived sample available

Criterios de exclusión

Brain metastasis and/or leptomeningeal disease (known or suspected)
Previous chemotherapy for colorectal cancer except adjuvant treatment with progression of disease documented \> 6 months after end of adjuvant treatment.
Previous oxaliplatin-based chemotherapy
Surgery (excluding diagnostic biopsy) or irradiation within 4 weeks prior to randomization
Concurrent or previous chronic systemic immune therapy, targeted therapy, anti-vascular epithelial growth factor (VEGF) therapy, epidermal growth factor receptor (EGFR) pathway targeting therapy not indicated in the study protocol

Peripheral neuropathy \>grade 1
Known hypersensitivity reaction to any of the components of the treatment.
Any concurrent malignancy other than basal cell cancer of the skin, or pre-invasive cancer of the cervix. (Subjects with a previous malignancy but without evidence of disease for ≥ 5 years will be allowed to enter the study)
Pregnancy (absence to be confirmed by ß-human chorionic gonadotrophin test) or lactation period
Known drug abuse/alcohol abuse
Legal incapacity or limited legal capacity
Medical or psychological condition which in the opinion of the investigator would not permit the subject to complete the study or sign meaningful informed consent
Participation in another clinical study within the 30 days before randomization
Significant disease which, in the investigator's opinion, would exclude the subject from the study
