Bi-weekly Cetuximab Combined With 5-fluorouracil/Leucovorin/Oxaliplatin (FOLFOX-6) in Metastatic Colorectal Cancer (CEBIFOX)
Cetuximab is normally given as a weekly schedule in the therapy of patients with metastatic colorectal cancer.
In order to improve the convenience for the patients in first line-therapy this study will evaluate the efficacy and safety of a bi-weekly combination of cetuximab with FOLFOX.

Experimental: Cetuximab + Folfox-6-regime
Cetuximab 500 mg/m² administered as an intravenous infusion over 120 minutes on day 1 every 2 weeks. Combined with the following FOLFOX-6-regime:
Oxaliplatin 85 mg/m² i.v. for 2 h on day 1, Folinic acid 400 mg/m² i.v. for 2 h concurrently with Oxaliplatin on day 1, Fluorouracil 400 mg/m² i.v. bolus after Folinic Acid on day 1, followed by Fluorouracil 2400 mg/m² i.v. over 46 h.
500 mg /m² cetuximab as an intravenous infusion over 120 minutes on day 1 every 2 weeks
Other Name: Erbitux®
For years the effective treatment of advanced colorectal carcinoma (CRC) was limited to fluorouracil (5-FU). Combination of 5-FU or a 5-FU analog with oxaliplatin, which has some antitumor activity as a single agent, shows synergistic activity. Combining oxaliplatin with a twice monthly folinic acid/5-FU schedule leads to a further improvement in first-line treatment of advanced CRC thus emerging to a standard regimen in first-line therapy of metastatic CRC.
Cetuximab is normally given as a weekly schedule. As recently shown a biweekly schedule with 500 mg/m² instead of the weekly standard regimen (initial dose of 400 mg/m² followed by 250 mg/m² every week) exhibits similar pharmacokinetic results with a comparable efficacy.
In order to improve the convenience for the patients, this study will evaluate the efficacy and safety of a bi-weekly combination of cetuximab with FOLFOX. Out of the various FOLFOX regimens the most convenient FOLFOX-6 schedule is chosen for the study, which has been tested before in two studies in combination with the standard weekly schedule of cetuximab. Recent data suggest a decreased efficacy of cetuximab in patients bearing a k-ras mutation in their CRC. Therefore only patients with no evidence for a mutated k-ras gene in the colorectal carcinoma cells will be included in this study.
