STI571 Compared With Interferon Alfa Plus Cytarabine in Treating Patients With Newly Diagnosed Chronic Myelogenous Leukemia

• Status: Completed
• Trial end date: 2007-03-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Biological therapies such as interferon-alfa and STI571 may interfere with the growth of cancer cells. It is not yet known if STI571 is more effective than interferon alfa plus cytarabine for chronic myelogenous leukemia.

PURPOSE: Randomized phase III trial to compare the effectiveness of STI571 with that of interferon alfa plus cytarabine in treating patients who have newly diagnosed chronic myelogenous leukemia.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Novartis
• Collaborator: National Cancer Institute (NCI)
• Treatments: Cytarabine; Imatinib Mesylate; Interferon-alpha; Interferons
