Brief Summary: RATIONALE Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die Combining imatinib mesylate and chemotherapy may kill more cancer cells
PURPOSE Phase III trial to study the effectiveness of imatinib mesylate plus cytarabine in treating patients who have newly diagnosed chronic myeloid leukemia
Detailed Description: OBJECTIVES
Determine the maximum tolerated dose of imatinib mesylate and cytarabine in patients with newly diagnosed chronic phase chronic myeloid leukemia Determine the feasibility of this regimen as defined by dose-limiting toxicity of this regimen and treatment-related mortality in no more than 5 of these patients Determine the rate and duration of molecular response complete hematological response and complete cytogenetic response in patients treated with this regimen Determine the time to treatment failure of patients treated with this regimen Determine the overall survival of patients treated with this regimen
OUTLINE This is a multicenter dose-escalation study of imatinib mesylate and cytarabine
Patients receive oral imatinib mesylate alone once daily on days 1-21 Patients then receive oral imatinib mesylate once daily and cytarabine IV over 1-3 hours on days 1-7 Combination therapy repeats every 28-42 days for 2 courses Patients then receive maintenance oral imatinib mesylate once daily Treatment continues in the absence of disease progression or unacceptable toxicity
Cohorts of 5-20 patients receive escalating doses of imatinib mesylate and cytarabine until the maximum tolerated dose MTD is determined The MTD is defined as the dose preceding that at which at least 55 510 or 520 patients experience dose-limiting toxicity
Patients are followed every 6 months
PROJECTED ACCRUAL A total of 30-60 patients will be accrued for this study within 2 years
