Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of combining temozolomide and O6-benzylguanine in treating children who have solid tumors that have not responded to previous therapy.


Clinical Trial Description

OBJECTIVES:

- Determine the maximum tolerated dose of temozolomide administered with a biologically active dose of O6-benzylguanine (O6-BG) in children with refractory solid tumors.

- Determine the dose-limiting toxicity and the toxicity profile of this combination in these patients.

- Assess the plasma pharmacokinetics of O6-BG and its active metabolite, 8-oxo-O6-BG, in these patients.

- Assess the plasma pharmacokinetics of this combination in these patients.

- Correlate levels of alanine-glyoxylate aminotransferase in peripheral blood mononuclear cells with the degree of hematologic toxicity of this combination in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive O6-benzylguanine (O6-BG) IV over 1 hour followed 30 minutes later by oral temozolomide daily for 5 days. Treatment continues every 28 days for up to 12 courses in the absence of unacceptable toxicity or disease progression.

Sequential dose escalation of O6-BG is followed by sequential dose escalation of temozolomide. Cohorts of 3-6 patients receive escalating doses of O6-BG and temozolomide until the maximum tolerated dose (MTD) of each is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 6 patients experience dose-limiting toxicity.

Quality of life is assessed at baseline and prior to courses 1, 3, 6, 8, and 12.

PROJECTED ACCRUAL: A total of 21-48 patients will be accrued for this study within 1-2 years. ;
