Resumen
Fecha de inicio: 1 de enero de 2004
Fecha en la que se inscribió al primer participante.OBJECTIVES: Primary I. Determine the maximum tolerated dose and recommended phase II dose of bortezomib in children with refractory or recurrent leukemia. II. Determine the toxic effects of this drug in these patients. III. Determine the pharmacokinetics of this drug in these patients. Secondary I. Determine, preliminarily, the antitumor activity of this drug in these patients. II. Determine, preliminarily, the biologic activity of this drug in these patients. OUTLINE: This is a dose-escalation, open-label, multicenter study. Patients receive bortezomib IV over 3-5 seconds on days 1, 4, 8, and 11. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of bortezomib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. PROJECTED ACCRUAL: A total of 3-36 patients will be accrued for this study within 1.5-36 months.
