Brief Summary: RATIONALE Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die
PURPOSE Phase I trial to study the effectiveness of MS-275 in treating patients who have hematologic cancer
Detailed Description: OBJECTIVES
Determine the toxic effects and pharmacokinetics of MS-275 in patients with poor-risk hematologic malignancy Determine whether this drug induces changes in hematologic differentiation in terms of changes in morphology cell surface marker expression and acetylation status in these patients Determine whether this drug induces clinical response in these patients
OUTLINE This is a dose-escalation study
Patients receive oral MS-275 on days 1 8 15 and 22 Courses repeat every 6 weeks in the absence of disease progression or unacceptable toxicity
Cohorts of 3-6 patients receive escalating doses of MS-275 until the maximum tolerated dose MTD is determined The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity
PROJECTED ACCRUAL Approximately 25-30 patients will be accrued for this study
