Gefitinib in Treating Children With Refractory Solid Tumors
A Phase I Study Of ZD1839 (Iressa TM), An Oral Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor, In Children With Refractory Solid Tumors
調査の概要
詳細な説明
PRIMARY OBJECTIVES:
I. Determine the maximum tolerated dose of gefitinib in children with refractory solid tumors.
II. Determine the dose-limiting toxicity of this drug in these patients. III. Determine the pharmacokinetics of this drug in these patients. IV. Determine, preliminarily, the antitumor activity of this drug in these patients.
V. Correlate the pharmacogenetic polymorphisms of this drug with pharmacokinetics and pharmacodynamics in these patients.
OUTLINE: This is a dose-escalation, multicenter study. If myelosuppression is found to be the dose-limiting toxicity, patients are stratified according to prior therapy (more than 2 multiagent chemotherapy regimens or radiotherapy to more than 20% of the bone marrow or stem cell transplantation with or without total body irradiation vs more than 2 single-agent phase I or phase II agents) and extent of disease (bone marrow involvement vs meeting none of the stratum I criteria).
Patients receive oral gefitinib once daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of gefitinib 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: Approximately 3-45 patients will be accrued for this study.
