Brief Summary: RATIONALE The TP-38 toxin can locate tumor cells and kill them without harming normal cells Giving TP-38 toxin directly into the tumor may kill more tumor cells

PURPOSE This phase III trial is studying the side effects and best dose of TP-38 toxin administered directly into the brain and to see how well it works in treating young patients with recurrent or progressive supratentorial high-grade glioma
Detailed Description: OBJECTIVES

Primary

Phase I

Determine the maximum safe volume rate and maximum tolerated infusion concentration of TGFa-PE38 toxin TP-38 infused through 2 or 3 catheters in pediatric patients with recurrent or progressive supratentorial high-grade glioma
Describe the toxic effects of this drug in these patients
Phase II

Estimate the efficacy of this drug in terms of post-infusion survival in these patients

Secondary

Phase I and II

Determine the prevalence of epidermal growth factor receptor EGFR expression and phosphorylation activity in patients treated with this drug
Correlate EGFR expression with qualitative measures eg histology grade and other tumor characteristics and tumor response survival and progression-free survival in patients treated with this drug
Phase II Only

Estimate the objective response rate in patients treated with this drug
Estimate the progression-free survival of patients treated with this drug

OUTLINE This is a dose-escalation multicenter study Patients in the phase I portion of the study are stratified according to the number of successfully placed catheters 3 catheters vs 2 catheters Patients in the phase II portion of the study are stratified according to time of recurrence of high-grade glioma first vs second or greater and by surgery extent surgical resection vs stereotactic biopsy for those with first recurrence only

Phase I Patients undergo stereotactic biopsy or resection of the tumor followed by intratumoral or tumor bed catheter placement for treatment infusion Within 12-48 hours after intratumoral or tumor bed catheter placement patients receive TGFa-PE38 toxin TP-38 intratumorally through 2 or 3 catheters over 33 to 124 hours Treatment continues in the absence of disease progression or unacceptable toxicity

Cohorts of 3-6 patients in each stratum receive escalating volumes until the maximum safe volume MSV is determined Cohorts of 3-6 patients in each stratum receive escalating concentrations at the MSV until the maximum tolerated infusion concentration MTIC is determined The MSV and MTIC are defined as the volume and concentration preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity

Phase II Patients receive treatment as in phase I at the MSV and MTIC

Phase I patients are followed post catheter placement daily during TP-38 infusion at 30 days and then every 2 months for 1 year Phase II patients will be followed for an additional year

PROJECTED ACCRUAL A total of 6-105 patients 6-60 for phase I and 45 for phase II will be accrued for this study
