Brief Summary

This phase II trial is studying imatinib mesylate to see how well it works in treating patients with chronic myelogenous leukemia. Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth

Detailed Description

OBJECTIVES:

I. Determine the response rate in patients with Philadelphia chromosome positive chronic phase chronic myelogenous leukemia treated with imatinib mesylate.

II. Determine the disease-free survival of patients treated with this drug. III. Determine the pharmacokinetics of this drug in these patients. IV. Determine the toxic effects of this drug in these patients. V. Determine the rates of hematological, cytogenetic, and molecular response and time to response in patients treated with this drug.

OUTLINE: This is a multicenter study. Patients are stratified according to disease (chronic myelogenous leukemia [CML] in first chronic phase after failing interferon therapy or demonstrating intolerance to interferon [closed to accrual as of 12/05/03] vs CML relapsing after stem cell transplantation or in second or subsequent chronic phase [closed to accrual as of 7/29/05] vs newly diagnosed CML in first chronic phase with no prior treatment [closed to accrual as of 7/29/05] vs newly diagnosed CML in first chronic phase with no prior treatment).

Patients receive oral imatinib mesylate once daily on days 1-28. Courses repeat every 28 days for 1 year in the absence of disease progression or unacceptable toxicity. Patients who fail to achieve a complete hematologic response after 3 courses or a partial or complete cytogenic response after 6 courses are removed from the study.

PROJECTED ACCRUAL: A total of 109 patients (30 for stratum I [closed to accrual as of 12/05/03] and stratum II [closed to accrual as of 7/29/05], 34 for stratum III [closed to accrual as of 7/29/05], and 45 for stratum IV) will be accrued for this study within 2 years.

Treatment (imatinib mesylate)

Patients receive oral imatinib mesylate once daily on days 1-28. Courses repeat every 28 days for 1 year in the absence of disease progression or unacceptable toxicity. Patients who fail to achieve a complete hematologic response after 3 courses or a partial or complete cytogenic response after 6 courses are removed from the study.

Eligibility Criteria

Inclusion Criteria

• Diagnosis of Philadelphia chromosome positive (Ph+) chronic phase chronic myelogenous leukemia (CML)
• Stratum I (closed to accrual as of 12/05/03):

• CML in first chronic phase with resistance to interferon alfa (IFN-A) therapy defined as one of the following:

• WBC count at least 20,000/mm^3 after at least 3 months of treatment with an IFN-A-containing regimen
• Rising WBC count (at least 100% increase to a level of at least 20,000/mm^3) by two samples at least two weeks apart while receiving treatment with an IFN-A-containing regimen
• At least 66% Ph+ cells in bone marrow after 1 year of IFN-A therapy
• At least 30% increase in Ph+ cells in bone marrow after IFN-A-induced cytogenetic response while continuing to receive IFN-A therapy
• Intolerance to interferon therapy defined as more than two grade 2 toxic effects or any grade 3 toxic effect related to interferon therapy, except grade 3 fever, that is persistent beyond the first 28-day course of therapy and unresponsive to standard supportive care interventions
