Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - imatinib mesilate
Treatment: Drugs - interferon-alpha (INF-a)
Treatment: Drugs - cytarabine (ARA-C)

Experimental: imatinib (STI571) - 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.

Active comparator: IFN-a+Ara-C - In the first-line treatment period participants received 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 injections for 10 days every month. 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 the second-line treatment period to receive imatinib (STI571). IFN treatment was discontinued with protocol amendment 6. Maximum study duration was 8 years.


Treatment: Drugs: imatinib mesilate
imatinib supplied as 100 mg and 400 mg tablets or 100 mg capsules.

Treatment: Drugs: interferon-alpha (INF-a)
interferon-alpha (IFN-a) subcutaneous (SC) injections escalated over 4 weeks to achieve a target dose of 5 MU/m\^2/day.

Treatment: Drugs: cytarabine (ARA-C)
cytarabine 20 mg/m\^2/day (max 40 mg) SC for 10 days every month.
