Arm 2
Active Comparator
Experimental
Arm I
Arm II
Patients receive bevacizumab IV over 30-90 minutes on day 1. Patients also receive FOLFIRI chemotherapy comprising irinotecan hydrochloride IV over 1 hour and leucovorin calcium IV over 2 hours on day 1 and fluorouracil IV continuously over 46 hours on days 1 and 2. Treatment repeats every 2 weeks for up to 12 courses in the absence of disease progression or unacceptable toxicity.
Patients receive bevacizumab and FOLFIRI chemotherapy (B-FOLFIRI) as in arm I. Treatment repeats every 2 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients then receive bevacizumab IV over 30-90 minutes on day 1 and oral capecitabine once every 12 hours on days 1-14. Treatment repeats every 3 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.
