Overall survival was defined as the time between date of randomization and death due to any cause. The time was censored at last examination date for patients who were still being treated and at date of last contact for patients who discontinued treatment. Kaplan-Meier estimates of the percentage of participants at each time point was calculated. This outcome was measured in all randomized patients, regardless of whether crossover occurred, i.e., events that occurred in patients, who had crossed over, were attributed following crossover to the original randomized treatment.

| imatinib (STI571) | EXPERIMENTAL | 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-a+Ara-C | ACTIVE_COMPARATOR | 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. |

Interferon-alpha is used for the treatment of Chronic Myelogenous Leukemia (CML). It was studied in a Phase 3 clinical trial as an active comparator against imatinib in patients with newly diagnosed Philadelphia chromosome positive CML. The trial enrolled 1106 participants across multiple countries.
Interferon-alpha is developed by Novartis AG, which is listed on the stock exchange under the ticker NVS. The company conducted a Phase 3 clinical trial of the drug in patients with Chronic Myelogenous Leukemia.
Interferon-alpha is in Phase 3 clinical development for Chronic Myelogenous Leukemia. The Phase 3 trial, which was completed, compared the drug to imatinib in newly diagnosed patients with Philadelphia chromosome positive CML. The drug is investigational and not yet approved.
Interferon-alpha was studied in the completed Phase 3 clinical trial NCT00333840, titled "Safety and Efficacy of Imatinib Versus Interferon-α Plus Cytarabine in Patients With Newly Diagnosed Philadelphia Chromosome Positive Chronic Myelogenous Leukemia." The trial enrolled 1106 patients and was conducted in multiple countries.
No, interferon-alpha is not the same as imatinib. In the Phase 3 clinical trial NCT00333840, interferon-alpha was used as an active control and compared against imatinib in patients with newly diagnosed Philadelphia chromosome positive Chronic Myelogenous Leukemia.
