Summary
Study start date: June 1, 2004
Actual date on which the first participant was enrolled.OBJECTIVES: * Determine the confirmed complete and partial response rate in women with progressive stage IV adenocarcinoma of the breast treated with imatinib mesylate and capecitabine. * Determine the 6-month progression-free survival of patients treated with this regimen. * Determine the toxicity of this regimen in these patients. * Correlate, preliminarily, c-kit and platelet-derived growth factor receptor expression with estrogen and progesterone receptor status, response, survival, and time to disease progression in patients treated with this regimen. OUTLINE: This is a multicenter study. Patients receive oral imatinib mesylate\* once daily on days 1-21 and oral capecitabine twice daily on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. NOTE: \*If the patient tolerates the starting dose of imatinib mesylate in course 1, the dose will be increased in subsequent courses. Patients are followed every 6 months for 3 years. PROJECTED ACCRUAL: A total of 25-70 patients (25-45 patients with measurable disease and 25 with non-measurable disease) will be accrued for this study within 2 years.
