Trial Description


RATIONALE: Monoclonal antibodies, such as cetuximab and 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. Cetuximab may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Drugs used in chemotherapy, such as fluorouracil, leucovorin, oxaliplatin, and irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving monoclonal antibodies together with combination chemotherapy may kill more tumor cells. It is not yet known whether combination chemotherapy is more effective with cetuximab and/or bevacizumab in treating patients with colorectal cancer.

PURPOSE: This randomized phase III trial is studying cetuximab and/or bevacizumab when given together with combination chemotherapy to compare how well they work in treating patients with metastatic colorectal cancer.

Further Study Information



  • Compare overall survival of patients with previously untreated metastatic colorectal cancer treated with cetuximab and/or bevacizumab in combination with either oxaliplatin, fluorouracil, and leucovorin calcium (FOLFOX) OR irinotecan hydrochloride, fluorouracil, and leucovorin calcium (FOLFIRI). (Arm III [cetuximab and bevacizumab in combination with FOLFOX or FOLFIRI] closed to accrual as of 09/10/2009)


  • Compare response, progression-free survival, time to treatment failure, and duration of response in patients with unresectable disease treated with these regimens.
  • Compare toxicity and 60-day survival of patients with unresectable disease treated with these regimens.
  • Determine whether patients with unresectable disease become eligible for surgical resection after treatment with these regimens.

OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to physician-selected chemotherapy (oxaliplatin, leucovorin calcium, and fluorouracil [FOLFOX] vs irinotecan hydrochloride, leucovorin calcium, or fluorouracil [FOLFIRI]), prior adjuvant chemotherapy (yes vs no), and prior pelvic radiotherapy (yes vs no). Patients are randomized to 1 of 3 treatment arms. (Arm III closed to accrual as of 09/10/2009)

  • Arm I: Patients receive oxaliplatin IV over 2 hours or irinotecan hydrochloride IV over 30-90 minutes; leucovorin calcium IV over 2 hours; fluorouracil IV continuously over 46-48 hours; and bevacizumab IV over 30-90 minutes on days 1, 15, 29, and 43.
  • Arm II: Patients receive oxaliplatin or irinotecan hydrochloride, leucovorin calcium, and fluorouracil as in arm I. Patients also receive cetuximab IV over 1-2 hours on days 1, 8, 15, 22, 29, 36, 43, and 50.
  • Arm III (closed to accrual as of 09/10/2009): Patients receive oxaliplatin or irinotecan hydrochloride, leucovorin calcium, fluorouracil, and bevacizumab as in arm I. Patients also receive cetuximab as in arm II.

In all arms, treatment repeats every 56 days for at least 2 courses in the absence of disease progression, unacceptable toxicity, or planned surgery with curative intent.

For patients whom elective surgery is contemplated, bevacizumab must be discontinued for at least 8 weeks before surgery and may not be resumed for at least 4 weeks after surgery. Patients who undergo complete resection of metastatic disease are removed from study.

After completion of study treatment, patients are followed up every 2 months for 5 years and then every 6 months for 5 years.

PROJECTED ACCRUAL: A total of 2,900 patients will be accrued for this study.
