简要总结
This phase I trial is studying the side effects and best dose of tanespimycin in treating young patients with recurrent or refractory leukemia or selected solid tumors. Drugs used in chemotherapy, such as tanespimycin, work in different ways to stop cancer cells from dividing so they stop growing or die.
详细描述
PRIMARY OBJECTIVES:
I. Determine the dose-limiting toxicity and maximum tolerated dose (MTD) of 17-N-allylamino-17-demethoxygeldanamycin (17-AAG) in pediatric patients with recurrent or refractory leukemia or selected solid tumors.
II. Determine the levels of key proteins known to influence cancer cell survival and proliferation in patients treated with this drug at the MTD.
SECONDARY OBJECTIVES:
I. Determine the pharmacokinetics of this drug in these patients. II. Evaluate effects of genetic polymorphisms known to alter the activity of enzymes involved in the metabolism of this drug.

研究组 & 干预措施
Treatment (tanespimycin)
Patients receive tanespimycin IV over 2-6 hours on days 1, 4, 8, and 11 (for patients with solid tumors) OR days 1, 4, 8, 11, 15, and 18 (for patients with leukemia). Courses for all patients repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of tanespimycin until the 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. At least 15 patients are treated at the MTD.
