Oxaliplatin in Treating Patients With Newly Diagnosed Glioblastoma Multiforme

Adult Glioblastoma Clinical Trial

Official title: Phase I/II Trial of Oxaliplatin as Neoadjuvant Treatment in Adults With Newly Diagnosed Glioblastoma Multiforme

Status Terminated

Clinical Trial Summary

This phase I/II trial is studying the side effects and best dose of oxaliplatin in treating patients with newly diagnosed glioblastoma multiforme. Drugs used in chemotherapy, such as oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing

Clinical Trial Description

OBJECTIVES:

I. Determine the maximum tolerated dose of oxaliplatin in patients with newly diagnosed glioblastoma multiforme who are receiving or not receiving anticonvulsants known to be metabolized by P450.

II. Determine the dose-limiting toxicity and safety profile of this drug in this patient population.

III. Assess the pharmacokinetics of this drug on this schedule and determine the effects of P450-inducing anticonvulsants on the pharmacokinetics in these patients.

IV. Determine the radiographic response rate in patients treated with this drug.

V. Determine survival and drug toxicity in these patients.

OUTLINE: This is a phase I dose-escalation study of oxaliplatin followed by a phase II study. Patients are stratified according to whether concurrent anticonvulsant drugs induce P450 (yes vs modest/no or no drugs).

Phase I: Patients receive oxaliplatin IV over 2 hours on day 1. Treatment repeats every 14 days for a maximum of 6 courses in the absence of unacceptable toxicity or disease progression.

Cohorts of 3-6 patients (per stratum) receive escalating doses of oxaliplatin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

Phase II: Patients receive oxaliplatin as in phase I at the MTD determined in phase I.

Patients are followed at 1 month, every 2 months until disease progression, and then monthly thereafter.

PROJECTED ACCRUAL: Approximately 24 patients (12 per stratum) will be accrued for the phase I part of this study within 8-12 months. A total of 18-35 patients will be accrued for the phase II part of this study within 5-12 months. ;
