S0338, Imatinib Mesylate and Capecitabine in Treating Women With Progressive Stage IV Breast Cancer

• Status: Completed
• Trial end date: 2008-12-01
• Target enrollment: 0
• Participant gender: Female

Summary

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Drugs used in chemotherapy, such as capecitabine, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining imatinib mesylate with capecitabine may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving imatinib mesylate together with capecitabine works in treating women with progressive stage IV breast cancer.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
