STEAM (Sequencing Triplet with Avastin and Maintenance): Folfoxiri/Bevacizumab Regiments (Concurrent and Sequential) vs. Folfox/Bevacizumab in First-Line Metastatic Colorectal Cancer



Trial Phase

Phase II

Trial Purpose and Description

Trial Purpose

This randomized, open-label, multicenter study will evaluate the efficacy and safety of FOLFOXIRI/Avastin (bevacizumab) regimens (concurrent and sequential) versus FOLFOX/Avastin in first-line in patients with metastatic colorectal cancer. Patients will be randomized to receive Avastin 5 mg/kg intravenously every 2 weeks with either concurrent or sequential FOLFOXIRI or with FOLFOX for 4 to 6 months of induction therapy, followed by maintenance therapy with Avastin plus either leucovorin/5-fluorouracil or capecitabine until disease progression occurs. After disease progression, patients will receive treatment with a fluoropyrimidine-based chemotherapy plus Avastin.
