OBJECTIVES: I. Determine the response rate, duration of response, and time to progression in patients with metastatic and/or locally recurrent adenocarcinoma of the colon or rectum treated with ISIS 2503, an antisense inhibitor of H-ras. II. Determine the safety profile of this regimen in these patients.
OUTLINE: This is a multicenter study. Patients receive ISIS 2503 IV continuously for 14 days. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity.
PROJECTED ACCRUAL: A total of 14-25 patients will be accrued for this study within 1 year.
