Interventions

• 5-fluorouracil — DRUG
  Participants in Arm A will receive 3200 milligrams per square meter (mg/m\^2) by 48-hour continuous intravenous (IV) infusion every 2 weeks, during the 4-6 months' induction followed by maintenance therapy including bolus dose of 400 mg/m\^2, followed by a 46-hour continuous infusion (2400 mg/m\^2) every 2 weeks per investigator's discretion. Participants in Arm B and C will receive a bolus dose of 400 mg/m\^2, followed by a 46-hour continuous infusion (2400 mg/m\^2) every 2 weeks during the 4-6 months of induction and maintenance per investigator's discretion.
• bevacizumab — DRUG
  Participants will receive 5 mg/kg IV every 2 weeks during the first 4-6 months induction phase, followed by 5 mg/kg IV every 2 weeks or 7.5 mg/kg IV every 3 weeks during maintenance therapy, and 2.5 mg/kg per week reinduction after disease progression.
• capecitabine — DRUG
  Participants will receive 1000 or 850 mg/kg orally twice daily as per investigator's discretion on Day 1 to 14, repeated every 3 weeks in maintenance phase.
• irinotecan — DRUG
  Participants will receive IV infusion of 165 mg/m\^2 over 1 hour every 2 weeks (Arm A) or IV infusion of 180 mg/m\^2 over 1 hour in 2 x 2 weeks cycles alternating months (in Arm B), during 4-6 months induction phase.
• folinic acid — DRUG
  Participants will receive IV infusion of 200 mg/m\^² (Arm A) or 400 mg/m\^2 (Arm B or C) over 2 hours every 2 weeks, during 4-6 months induction phase followed by IV infusion of 400 mg/m\^2 in the maintenance therapy.
• oxaliplatin — DRUG
  Participants will receive 85 mg/m\^2 over 2 hours as IV infusion every 2 weeks (Arm A, C ) or 2 x 2 week cycles alternating months (Arm B), during 4-6 months induction phase .

Study Details

This randomized, open-label, multicenter study will evaluate the efficacy and safety of folinic acid (leucovorin), 5-fluorouracil (5-FU), oxaliplatin, and irinotecan (FOLFOXIRI) / bevacizumab regimens (concurrent and sequential) versus folinic acid (leucovorin), 5-fluorouracil, and oxaliplatin (FOLFOX) / bevacizumab in first-line in participants with metastatic colorectal cancer. Participants will be randomized to receive bevacizumab 5 milligrams per kilogram (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 bevacizumab plus either leucovorin/5-fluorouracil or capecitabine until disease progression occurs. After disease progression, participants will receive treatment with a fluoropyrimidine-based chemotherapy plus bevacizumab.

Arms

• Experimental: Arm A: Concurrent FOLFOXIRI + Bevacizumab
  Participants will receive concurrent FOLFOXIRI along with 5 mg/kg of bevacizumab with treatment cycle of 2 weeks during first 4 month induction phase (plus optional 2 months of induction for participants who exhibit good response and tolerate the regimen) followed by administration of 5-FU with bevacizumab or capecitabine with bevacizumab as per investigator's discretion in maintenance phase. Following progression on first-line therapy (PD1), bevacizumab (dose equivalent, 2.5 mg/kg/week) will be administered as second-line therapy in combination with fluoropyrimidine based chemotherapy at the investigator's discretion.
• Experimental: Arm B: Sequential FOLFOXIRI + Bevacizumab
  Participants will receive alternating 4-week administrations of FOLFOX/bevacizumab and folinic acid (leucovorin), 5-FU, and irinotecan (FOLFIRI) /Bevacizumab with a treatment cycle of 2 weeks during first 4-month induction phase (plus optional 2 months of induction for participants who exhibit good response and tolerate the regimen) followed by administration of 5-FU with bevacizumab or capecitabine with bevacizumab as per investigator's discretion in maintenance phase. Following progression on first-line therapy (PD1), bevacizumab (dose equivalent, 2.5 mg/kg/week) will be administered as second-line therapy in combination with fluoropyrimidine based chemotherapy at the investigator's discretion.
• Experimental: Arm C: FOLFOX + Bevacizumab
  Participants will receive FOLFOX along with 5 mg/kg of bevacizumab with treatment cycle of 2 weeks during first 4-month induction phase (plus optional 2 months of induction for participants who exhibit good response and tolerate the regimen) followed by administration of 5-FU with bevacizumab or capecitabine with bevacizumab as per investigator's discretion in maintenance phase. Following progression on first-line therapy (PD1), bevacizumab (dose equivalent, 2.5 mg/kg/week) will be administered as second-line therapy in combination with fluoropyrimidine based chemotherapy at the investigator's discretion.
