About this study

Official title: A Phase III Study of STI571 Versus Interferon-a (IFN-a) Combined With Cytarabine (Ara-C) in Patients With Newly Diagnosed Previously Untreated Philadelphia Chromosome Positive (Ph+) Chronic Myelogenous Leukemia in Chronic Phase (CML-CP)

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.

Read the detailed description

OBJECTIVES: I. Compare the time to treatment failure and overall survival in patients with newly diagnosed, previously untreated, Philadelphia chromosome positive, chronic phase chronic myelogenous leukemia treated with STI571 vs interferon alfa combined with cytarabine. II. Compare the quality of life and disease and treatment related toxicities in patients treated with these 2 regimens. III. Compare the rate and duration of complete hematologic response (CHR) and major cytogenetic response (MCR) in patients treated with these 2 regimens. IV. Compare the rate and duration of MCR and CHR attributable to crossover therapy in patients who crossover to receive STI571 OR interferon alfa combined with cytarabine. V. Compare the tolerability and safety of these regimens in these patients. VI. Determine the population pharmacokinetics of STI571 in these patients.

OUTLINE: This is a randomized, open label, crossover, multicenter study. Patients are randomized to one of two treatment arms: Arm I: Patients receive oral STI571 once daily. Arm II: Patients receive interferon alfa (IFN-A) subcutaneously (SQ) daily. Gradual intrapatient dose escalation is performed until the target dose of IFN-A is achieved. Patients then also receive cytarabine SQ daily for 10 days every month. Cytarabine is discontinued when a complete cytogenetic response is achieved and confirmed on two consecutive occasions not more than 3 months apart. Both arms: Courses repeat monthly in the absence of progression to accelerated phase or blast crisis, or unacceptable toxicity. Patients with no complete hematologic response at 6 months, no major cytogenetic response at year 2, or loss of complete hematologic response (without progression to accelerated or blastic phase) discontinue treatment on the arm to which they were originally randomized and begin treatment on the other arm. Crossover courses repeat monthly in the absence of progression to accelerated phase or blast crisis, or unacceptable toxicity. Quality of life is assessed prior to study; monthly for the first 6 months of study; at 9, 12, 18, and 24 months; at time of crossover (if applicable); and at treatment discontinuation before year 2 (if applicable). All patients are followed every 3 months for up to 8 years.

PROJECTED ACCRUAL: A total of 850 patients (425 per arm) will be accrued for this study.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing recombinant interferon alfa, cytarabine and imatinib mesylate in people with Leukemia, run by Novartis at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00006343, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jan 2013.
