BMS-354825 in Treating Patients With Chronic Phase Chronic Myelogenous Leukemia That Is Resistant to Imatinib Mesylate

Study Overview
=================
Brief Summary
-----------------
RATIONALE: BMS-354825 may stop the growth of cancer cells by stopping the enzymes necessary for cancer cell growth. PURPOSE: This phase I trial is studying the side effects and best dose of BMS-354825 in treating patients with chronic phase chronic myelogenous leukemia that is resistant to imatinib mesylate.

Detailed Description
-----------------
OBJECTIVES: Determine the maximum tolerated dose, maximum administered dose, dose-limiting toxicity, and a recommended phase II dose of BMS-354825 in patients with chronic phase chronic myelogenous leukemia who have hematologic resistance to imatinib mesylate. Determine the safety and tolerability of this drug in these patients. Determine the plasma pharmacokinetics of this drug in these patients. Determine, preliminarily, the efficacy of this drug, in terms of hematologic, cytogenetic, and molecular responses in these patients. OUTLINE: This is an open-label, dose-escalation, multicenter study. Patients receive oral BMS-354825 once daily on days 1-5. Courses repeat every 7 days for at least 3 months in the absence of disease progression or unacceptable toxicity. Patients may receive further treatment in the absence of disease progression. Cohorts of 3-6 patients receive escalating doses of BMS-354825 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, 20 additional patients receive treatment as in phase I at the MTD of BMS-354825. Patients are followed for at least 30 days. PROJECTED ACCRUAL: Approximately 50 patients (30 for phase I and 20 for phase II) will be accrued for this study within 12-18 months.
