Bevacizumab and Chemotherapy |
Participants randomized to receive bevacizumab and chemotherapy. For these patients, bevacizumab was given in combination with chemotherapy at a dose of 5 mg/kg/week equivalent using 1 of 3 different scheduling options depending on the schedule of the adjuvant chemotherapy selected. After completing chemotherapy + bevacizumab (treatment period 1), patients in this arm received bevacizumab monotherapy up to a total duration of 1 year (treatment period 2). At the end of treatment (i.e., after approximately 55 weeks), patients were followed up until the end of the study. |
Chemotherapy |
Participants randomized to receive chemotherapy alone. For patients randomized to the chemotherapy alone arm, investigators could select from one of three chemotherapy regimens. After completing chemotherapy (treatment period 1) patients entered a post-treatment surveillance period for the remainder of the first year after randomization (treatment period 2). At the end of treatment (i.e., after approximately 55 weeks), patients were followed up until the end of the study. |
