Trial Information

Interstitial Infusion of IL 13-PE38QQR Cytotoxin in Recurrent Malignant Glioma: Phase I/II Study


- Determine the toxic effects and maximum tolerated dose (MTD) of interstitial
interleukin-13 PE38QQR immunotoxin in patients with malignant glioma.

- Determine the response rate, duration of response, time to response, overall survival,
and time to progression in patients treated with this regimen.

- Determine the toxic effects of this drug at the MTD in these patients.

OUTLINE: This is a dose-escalation, multicenter study.

Patients undergo stereotactic biopsy of brain tumor followed by CT guided stereotactic
placement of 2 intratumoral catheters on day 0. Patients with histologically confirmed
malignant glioma receive interleukin-13 PE38QQR immunotoxin interstitially over 96 hours
beginning on day 1. Patients with a residual enhancing mass undergo repeat catheter
placement on day 56 and then receive a second interstitial infusion beginning on day 57 in
the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of interleukin-13 PE38QQR immunotoxin until
the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 2 of
6 patients experience dose-limiting toxicity. Additional patients are treated at the MTD.

Patients are followed every 8 weeks.

PROJECTED ACCRUAL: A maximum of 30 patients will be accrued for phase I of the study within
6 months and a total of 12-35 patients will be accrued for phase II of the study within
10-12 months.
