RATIONALE: PS-341 may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth.
PURPOSE: Phase I trial to study the effectiveness of PS-341 in treating patients who have refractory or relapsed acute myeloid leukemia, acute lymphoblastic leukemia, chronic myeloid leukemia in blast phase, or myelodysplastic syndrome.

Official Title: | Phase I Study of PS-341 in Acute Myeloid Leukemias, Myelodysplastic Syndromes and Chronic Myeloid Leukemia in Blast Phase |
Study Start Date: | February 2000 |
OBJECTIVES: I. Determine the maximum tolerated dose of PS-341 in patients with refractory or relapsed acute myeloid leukemia, acute lymphoblastic leukemia, myelodysplastic syndrome, or chronic myeloid leukemia in blast phase. II. Assess the plasma pharmacology of this drug, its ability to inhibit proteasome function and to accelerate apoptosis in circulating blasts in this patient population. III. Assess the antileukemic effects of this drug in these patients.
OUTLINE: This is a dose-escalation study. Patients receive PS-341 IV bolus twice weekly for 4 weeks followed by 2 weeks of rest. Treatment continues for a maximum of 12 courses in the absence of unacceptable toxicity or disease progression. Cohorts of 2 patients receive escalating doses of PS-341 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose level associated with toxicity probability closest to 0.2 after 30 patients are treated.
PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study within 10 months.
