Phase II trial to study the effectiveness of imatinib mesylate in treating patients who have stage IV colorectal cancer. Imatinib mesylate may interfere with the growth of tumor cells by blocking certain enzymes necessary for cancer cell growth

Condition Intervention Phase
Recurrent Colon Cancer
Recurrent Rectal Cancer
Stage IV Colon Cancer
Stage IV Rectal Cancer
Drug: imatinib mesylate
Other: laboratory biomarker analysis
Phase 2

Primary Outcome Measures:
  • Response rate [ Time Frame: Up to 4 years ] [ Designated as safety issue: No ]

Enrollment: 37
Study Start Date: May 2002
Primary Completion Date: July 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment (imatinib mesylate)
Patients receive oral imatinib mesylate twice daily. Treatment continues for 8 weeks in the absence of disease progression or unacceptable toxicity. Patients with stable disease or better continue therapy until disease progression or 1 year after complete response.

Correlative studies

Detailed Description:


I. To determine response to Gleevec (Imatinib Mesylate) in patients with metastatic colorectal cancer and with c-Kit, Arg, Abl, or PDGF-R expression.

II. To determine the side effects of Imatinib Mesylate in patients with colorectal cancer.

III. To study the biologic effects of Imatinib Mesylate on the c-Kit and PDGF-R system and downstream signaling in metastatic colorectal cancer.


Patients receive oral imatinib mesylate twice daily. Treatment continues for 8 weeks in the absence of disease progression or unacceptable toxicity. Patients with stable disease or better continue therapy until disease progression or 1 year after complete response.
