CC-8490 in Treating Patients With Recurrent or Refractory High-Grade Gliomas

RATIONALE: Drugs used in chemotherapy, such as CC-8490, work in different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase I trial to study the effectiveness of CC-8490 in treating patients who have recurrent or refractory high-grade gliomas.

OBJECTIVES:

Primary

* Determine the maximum tolerated dose of CC-8490 in patients with recurrent or refractory high-grade gliomas.
* Determine, preliminarily, the toxic effects of this drug in these patients.
* Determine the pharmacokinetics of this drug in these patients.

Secondary

* Determine, preliminarily, the potential anti-glioma activity of this drug in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive oral CC-8490 once daily on days 1 and 3-28 (course 1 only). Beginning with course 2 and for all subsequent courses, patients receive oral CC-8490 once daily on days 1-28. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of CC-8490 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. Once the MTD is determined, a total of 10 patients are treated at that dose.

Patients are followed within 2 weeks.

PROJECTED ACCRUAL: A total of 34 patients will be accrued for this study.
