Homoharringtonine and Interferon Alfa in Treating Patients With Chronic Myelogenous Leukemia

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

Phase II trial to study the effectiveness of homoharringtonine and interferon alfa in treating patients with chronic myelogenous leukemia. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Interferon alfa may interfere with the growth of cancer cells. Combining chemotherapy with interferon alfa may kill more cancer cells.

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

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: Harringtonines; Homoharringtonine; Interferon-alpha; Interferons

Criteria
