Condition colorectal cancer
Treatments 5-fu, bevacizumab, levofolinic acid, oxaliplatin
Phase phase 2
Sponsor Hoffmann-La Roche
Start date August 2011
End date October 2016
Trial size 77 participants
Trial identifier NCT01383707, 2011-001364-22, ML25625


The multicenter, open-label, single-arm, non randomized, two-stage Simon's design, phase II study will evaluate the efficacy and safety of bevacizumab in combination with mFOLFOX-6 in participants with colorectal cancer and liver metastases. Participants will receive combination therapy of bevacizumab 5 milligrams per kilogram (mg/kg) intravenous (IV) dose and mFOLFOX-6 (Levofolinic acid, 5-Fluorouracil [5-FU] and oxaliplatin) every 2 weeks during Cycles 1-5 and Cycles 7-12. Participants will receive mFOLFOX-6 alone (without bevacizumab) on Cycle 6. In between Cycle 6 and 7, participants will undergo liver surgery if operable. Thereafter participants will receive bevacizumab (5 mg/kg IV every 2 weeks) alone for 52 weeks (26 cycles) after the end of the post-operative phase (maintenance therapy). At the end of the preoperative treatment phase (Cycles 1-6), participants showing different alternative conditions admitted by the protocol will undergo different management (alternative study designs 1 to 3).

Primary purpose treatment
Participants will receive combination therapy of bevacizumab 5 mg/kg IV dose and mFOLFOX-6 (folinic acid, 5-FU and oxaliplatin) on Day 1 of every 2 weeks' cycle for 5 cycles (Cycle 1-5), followed by 1 cycle (Cycle 6) of mFOLFOX6 alone (preoperative treatment phase). After 3 weeks of preoperative treatment phase, participants satisfying the surgical criteria for hepatic resectability will undergo a liver metastasectomy. Thereafter participants will receive combination therapy of mFOLFOX-6 + bevacizumab for another 6 cycles (Cycle 7-12); (post-operative treatment phase) followed by bevacizumab alone for 52 weeks (26 cycles) (maintanance therapy).
Participants will receive 5-FU 400 mg per meter-squared (mg/m^2) IV dose on Day 1 of each 2 weeks' cycle followed by 2400 mg/m^2, continuous infusion over 46 hours up to 12 cycles.
Participants will receive 5 mg/kg bevacizumab IV dose on Day 1 of each 2 weeks' cycle up to Cycle 5 and thereafter cycles 7 to 12; followed by maintenance therapy of 5 mg/kg IV every 2 weeks up to 52 weeks (26 cycles).
levofolinic acid
Participants will receive levofolinic acid 200 mg/m^2 IV infusion over 2 hours on Day 1 of each 2 weeks' cycle up to 12 cycles.
Participants will receive oxaliplatin 85 mg/m^2 IV infusion over 2 hours on Day 1 of each 2 weeks' cycle up to 12 cycles.
