Trial Description
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. Further Study Information 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. Eligibility Criteria DISEASE CHARACTERISTICS: - Diagnosis of Philadelphia chromosome positive, chronic phase chronic myelogenous leukemia (CML) meeting all of the following criteria*:
- Less than 15% blasts in peripheral blood and bone marrow
- Less than 20% basophils in peripheral blood
- Less than 30% blasts and promyelocytes in peripheral blood and bone marrow
- Platelet count at least 100,000/mm^3
- No extramedullary involvement (other than liver or spleen) NOTE: *Patients who previously met the criteria for accelerated phase or blast phase CML, responded to treatment, and currently meet the criteria for chronic phase CML are eligible
- Primary or acquired hematologic resistance to imatinib mesylate OR intolerance to imatinib mesylate defined as follows:
- Primary hematologic resistance is defined as failure to reach complete hematologic response (CHR) with a dose of 400 mg/day continued for at least 3 months
- Patients with hematological progression (i.e., WBC at least 10,000/mm^3 and rising consistently on at least 2 consecutive measurements obtained at least 14 days apart) while receiving imatinib mesylate of 400 mg/day are eligible if they have received less than 3 months of therapy
- Acquired hematologic resistance is defined as achieving a CHR, but subsequently developing a rising WBC to at least 10,000/mm^3
- WBC must be at least 10,000/mm^3 and rising on at least 2 measurements obtained at least 14 days apart with at least 1 of these measurements greater than 15,000/mm^3
- Intolerance is defined as having discontinued imatinib mesylate due to nonhematologic toxicity of any grade
- CD4^+ T-cell count at least 350/mm^3

Other - Fertile patients must use effective contraception for 1 month before, during, and 1 month after study participation
- No gastrointestinal tract bleeding within the past 6 months
- No connective tissue disorders
- No other serious uncontrolled medical disorder or active infection that would impair the ability to receive study therapy
- No dementia or altered mental status that would preclude giving informed consent
- No evidence of organ dysfunction or any clinically significant deviation from normal in physical examination, vital signs, EKG, or clinical laboratory determinations unrelated to CML
