Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Colorectal Cancer

Intervention: Avastin (Drug)

Phase: Phase 4

Status: Terminated

Sponsored by: Genentech

Official(s) and/or principal investigator(s):
Mary Sugrue, M.D., Study Director, Affiliation: Genentech


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.

Clinical Details

Official title: A Randomized, Open-Label Trial Comparing Two Avastin (Bevacizumab)-Based Treatment Regimens for the First-Line Treatment of Metastatic Colorectal Cancer

Study design: Interventional, Treatment

Primary outcome: To compare the efficacy, as measured by progression-free survival (PFS), of FOLFOX/Avastin followed by FOLFIRI/Avastin versus FOLFOX/Avastin followed by 5-FU/LV/Avastin as first-line therapy for previously untreated metastatic colorectal cancer.

Secondary outcome: To evaluate the tolerability of sequential treatment in subjects and to evaluate the safety of an irinotecan/Avastin-based regimen versus a 5-FU/Avastin regimen for previously untreated metastatic colorectal cancer.


Minimum age: 18 Years. Gender(s): Both.
