Summary
Brief summary (as posted)
The purpose of this study is to evaluate and compare the side effects and anti-leukemic benefits of imatinib with those of interferon and Ara-C for patients who have chronic myeloid leukemia (CML) in the chronic phase. Patients in this study will be randomized (1:1) to receive either interferon plus Ara-C or imatinib as initial treatment.

- imatinib (STI571)
- description
- In the first-line treatment period participants received imatinib 400 mg orally once daily in the morning. Hydroxyurea was permitted in the first 6 months to keep the white blood cell count (WBC) below 20.0 X 10\^9/liter. If protocol specific criteria applied, participants were eligible to crossover to receive interferon-alpha (IFN-a) subcutaneous (SC) injections escalated over 4 weeks to achieve a target dose of 5 MU/m\^2/day. After the maximum tolerated dose of IFN-a was achieved, participants also received cytarabine (ARA-C) 20 mg/m\^2/day (max 40 mg) SC injection for 10 days every month. Maximum study duration was 11.5 years.

IFN treatment was discontinued with protocol amendment 6. Maximum study duration was 8 years.
