Purpose:

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving combination chemotherapy together with bevacizumab after surgery may kill any tumor cells that remain after surgery. It is not yet known whether giving combination chemotherapy together with bevacizumab is more effective than combination chemotherapy alone in treating colon cancer. PURPOSE: This randomized phase III trial is studying two different combination chemotherapy regimens with or without bevacizumab to compare how well they work in treating patients who have undergone surgery for stage II or stage III colon cancer.


Study summary:

OBJECTIVES: Primary - Compare disease-free survival of patients with stage III colon cancer treated with adjuvant oxaliplatin, leucovorin calcium, and fluorouracil (FOLFOX-4) vs bevacizumab and FOLFOX-4 vs bevacizumab, oxaliplatin, and capecitabine. Secondary - Compare overall survival of patients treated with these regimens. - Compare the safety of these regimens in these patients. Tertiary - Compare the perceived convenience and satisfaction with chemotherapy in patients treated with these regimens. - Compare medical care utilization in patients treated with these regimens. OUTLINE: This is an open-label, randomized, multicenter study. Patients are stratified according to geographic region and disease stage (high risk stage II vs stage III N1 vs stage III N2). Patients are randomized to 1 of 3 treatment arms. - Arm I: Patients receive oxaliplatin IV over 2 hours on day 1 and leucovorin calcium (LV) IV over 2 hours and fluorouracil (5-FU) IV continuously over 22 hours on days 1 and 2. Treatment repeats every 14 days for a total of 12 courses. - Arm II: Patients receive bevacizumab IV over 30-90 minutes on day 1 and oxaliplatin, LV, and 5-FU as in arm I. Treatment repeats every 14 days for a total of 12 courses. Patients then receive bevacizumab IV alone over 30 minutes on day 1. Treatment with bevacizumab repeats every 21 days for a total of 8 courses. - Arm III: Patients receive bevacizumab IV over 30-90 minutes and oxaliplatin IV over 2 hours on day 1 and oral capecitabine twice daily on days 1-14. Treatment repeats every 21 days for a total of 8 courses. Patients then receive bevacizumab IV alone over 30 minutes on day 1. Treatment with bevacizumab repeats every 21 days for a total of 8 courses. In all arms, treatment continues in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed every 6 months for 4 years and then annually for 2 years. PROJECTED ACCRUAL: A total of 3,450 patients (1,150 per treatment arm) will be accrued for this study within 23 months.
