RATIONALE: Drugs used in chemotherapy, such as ABT-751, work in different ways to stop tumor cells from dividing so they stop growing or die.
PURPOSE: This phase I trial is studying the side effects of ABT-751 in treating young patients with refractory solid tumors.
|Condition or disease||Intervention/treatment||Phase|
|Brain and Central Nervous System Tumors Childhood Germ Cell Tumor Extragonadal Germ Cell Tumor Kidney Cancer Liver Cancer Neuroblastoma Ovarian Cancer Sarcoma Unspecified Childhood Solid Tumor, Protocol Specific||Drug: ABT-751||Phase 1|
- Determine the maximum tolerated dose and dose-limiting toxic effects of ABT-751 administered daily for 7 days every 21 days or daily for 21 days every 28 days in children with refractory solid tumors.
- Determine the toxicity spectrum of these regimens in these patients.
- Determine the pharmacokinetics of these regimens in these patients.
- Evaluate the pharmacodynamics of this drug by measuring the fraction of tubulin that is polymerized in the peripheral blood mononuclear cells of these patients before and after receiving this drug.
- Quantify responses in patients treated with these regimens.
- Assess the effect of this drug on tumor vascularity and tumor blood flow using dynamic enhanced MRI in these patients.
OUTLINE: This is an open-label, multicenter, dose-escalation study of 2 different schedules of ABT-751. Patients are assigned to 1 of 2 dosing schedules.
- Schedule 1 (closed to accrual as of 5/25/2009): Patients receive oral ABT-751 once daily on days 1-7. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
- Schedule 2 (closed to accrual as of 5/25/2009): Patients receive oral ABT-751 once daily on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
On each schedule, cohorts of 3-6 patients receive escalating doses of ABT-751 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, up to 9 patients (a minimum of 3 patients age 11 and under and 3 patients age 12 to 18) are treated at the MTD.
PROJECTED ACCRUAL: A maximum of 90 patients will be accrued for this study within 8 months.
