RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Phase II trial to study the effectiveness of monoclonal antibody therapy in treating patients who have relapsed or refractory metastatic colorectal cancer.

Study summary:

OBJECTIVES: - Determine the response rate of patients with metastatic colorectal cancer treated with monoclonal antibody ABX-EGF. - Determine the additional measures of clinical efficacy of this drug, in terms of progression-free survival, overall survival, and time to treatment failure, in these patients. - Determine the safety of this drug in these patients. OUTLINE: This is a multicenter study. Patients receive monoclonal antibody ABX-EGF IV over 1 hour weekly on weeks 1-8. Treatment repeats every 8 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients are followed at 4 weeks, every 3 months for 1 year, and then every 6 months for 1 year. PROJECTED ACCRUAL: A total of 20-100 patients will be accrued for this study.
