Bi-weekly Cetuximab Combined With 5-fluorouracil/Leucovorin/Oxaliplatin (FOLFOX-6) in Metastatic Colorectal Cancer
Bi-weekly Cetuximab Combined With FOLFOX-6 as First-line Treatment in Metastatic Colorectal Cancer Patients With Wild-type K-ras Status

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.

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.
