RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase I/II trial to study the effectiveness of procarbazine in treating patients who have progressive or recurrent astrocytoma, oligodendroglioma, or glioblastoma multiforme following treatment with radiation therapy.

Condition Intervention Phase
Brain and Central Nervous System Tumors Drug: procarbazine hydrochloride Phase 1 Phase 2

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: A Phase I/II Study of Oral Procarbazine in the Treatment of Recurrent High Grade Astrocytomas

Study Start Date: July 1999
Study Completion Date: August 2003
Detailed Description:


  • Determine the maximum tolerated dose of oral procarbazine when administered to patients with recurrent glioma receiving or not receiving anticonvulsants metabolized by the P450 hepatic enzyme complex.
  • Determine the pharmacokinetics of oral procarbazine, including any effects of hepatic enzyme inducing drugs, in these patients.
  • Assess the response rate to procarbazine in these patients.
  • Evaluate this regimen in terms of overall survival and duration of disease free survival in these patients.
  • Evaluate the toxicity of this regimen in these patients.

OUTLINE: Phase I of this study is a dose escalation study. Patients are stratified according to concurrent use of anticonvulsant drugs that induce cytochrome P450 (yes vs no drugs or modest-induction drugs).

  • Phase I: Patients receive oral procarbazine once daily for 5 days. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.

Cohorts of 6 patients receive escalating doses of oral procarbazine until the maximum tolerated dose (MTD) is determined.

  • Phase II: Once the MTD is determined, patients receive procarbazine as in Phase I.

Patients are followed every 2 months until death.

PROJECTED ACCRUAL: A total of 24-35 patients will be accrued for this study.
