简要总结
This phase I trial is studying the side effects and best dose of bortezomib in treating young patients with refractory or recurrent leukemia. Bortezomib may stop the growth of cancer cells by blocking the enzymes necessary for their growth.
详细描述
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.
