Imatinib Mesylate Plus Cytarabine in Treating Patients With Chronic Myelogenous Leukemia

• Status: Terminated
• Trial end date: 2011-07-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth.

PURPOSE: This phase II trial is studying giving imatinib mesylate together with cytarabine to see how well it works in treating patients with chronic phase chronic myelogenous leukemia.

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