Summary
Brief summary (as posted)
This open-label, prospective, single-arm, multicenter study will evaluate the relationship of the markers of inflammation and progression-free survival (PFS) in participants with previously untreated metastatic colorectal cancer. The study consists of two phases: Phase A treatment: oral capecitabine plus infusional oxaliplatin (XELOX) plus bevacizumab, or modified infusional 5-fluorouracil (5-FU), leucovorin (LV) and oxaliplatin (mFOLFOX6) plus bevacizmab administered until first disease progression. Participants will then continue with Phase B treatment: infusional 5-FU, LV and irinotecan (FOLFIRI) plus bevacizumab until second disease progression. The anticipated time on study treatment is 4 years.

- description
- The trial will consist of 2 phases of treatment. Phase A: Participants will receive bevacizumab 7.5 mg/kg intravenous (IV) infusion on Day 1 every 3 weeks in combination with XELOX (capecitabine and oxaliplatin) or bevacizumab 5 mg/kg IV on Day 1 every 2 weeks in combination with mFOLFOX6 (oxaliplatin, leucovorin, and 5-fluouracil) until first disease progression or occurrence of unmanageable toxicity. Phase B: Upon documented first disease progression, participants will continue receiving bevacizumab 5 mg/kg IV on Day 1 every 2 weeks in combination with FOLFIRI (irinotecan, leucovorin, and 5-fluouracil) until second disease progression or occurrence of unmanageable toxicity. Phase B treatment should commence within 4 weeks of the date of documented first disease progression.
