A Study to Compare Two Avastin-Based Treatment Regimens for the Treatment of Metastatic Colorectal Cancer

This is a randomized, open-label, active-control, multicenter trial comparing two oxaliplatin/Avastin-based treatment sequences as first-line therapy for metastatic colorectal cancer. The study is designed to compare the efficacy of these two treatment sequences with respect to progression free survival (PFS) and overall survival.
