Purpose
Objective: The primary purpose of this study is to test the safety and feasibility of giving a new experimental agent, called IL13-PE38QQR, directly into regions of the brain in patients with diffusely infiltrating pontine glioma (DIPG) or with recurrent or progressive supratentorial high-grade glioma (HGG) using a technique called convection-enhanced delivery or CED. CED uses continuous pressure to push large molecules through the membranes protecting the brain to reach brain tumors. At the same time, we can watch where the molecules go in the brain by attaching a tracer, gadolinium-DTPA, to the IL13-PE38QQR, which can then be seen in the brain with magnetic resonance imaging (MRI). Because we do not know the best dose to use in patients with DIPG or HGG, we will give increasing amounts of IL13-PE38QQR to small groups of patients with each type of brain tumor, known as a dose escalation study. Secondary purposes of this study include determining the effects of this experimental therapy on the tumor, and evaluating the physical changes in the tumor before and after the therapy.
Study Population: Twenty pediatric patients with recurrent or progressive DIPG or supratentorial HGG that have undergone standard treatment and who meet all the Inclusion and Exclusion Criteria may be enrolled. Eighteen patients will receive treatment; an additional two patients may be screening failures or unevaluable.
Design: We propose a Phase I single institution, open label, dose escalation (doses of 0.125, 0.25 and 0.5 micrograms/ml), safety and tolerability study of IL13-PE38QQR infused via CED into patients with either DIPG (up to 9 patients) or recurrent HGG (up to 9 patients). IL13-PE38QQR will be administered to regions of tumor determined by radiographic findings. Escalating dose levels will be evaluated in the following dose cohorts (3 patients per Cohort): Cohort 1 = 0.125 micrograms/ml, Cohort 2 = 0.25 micrograms/ml and Cohort 3 = 0.5 micrograms/ml.
Outcome Measures: To assess the safety, tolerability and potential efficacy of CED of IL13-PE38QQR, we will use detailed clinical and radiographic examinations. These will be performed at baseline and on post-infusion days 1, 28 and 60. After post-infusion day 60, clinical and radiographic studies will then be performed every 8 weeks until imaging or clinical evidence of recurrence/progressive disease or new treatment is initiated.

Eligibility
Ages Eligible for Study: up to 17 Years
Genders Eligible for Study: Both
Accepts Healthy Volunteers: No
Criteria
INCLUSION CRITERIA:
Age less than 18 years
Diagnosis: recurrent or progressive:
DIPG
HGG
Patients undergoing surgical resection must have measurable/evaluable disease prior to study entry.
Histopathologic Diagnosis
A histopathologic diagnosis is not required for patients with DIPG but a biopsy may be recommended if the patient has an atypical presentation or atypical findings on MR-imaging.
Histopathologic confirmation for patients with HGG is required. If necrosis is suspected based on MR-imaging and Nuclear Medicine scans, biopsy or surgical resection for confirmation of disease progression may be required.
Prior Therapy
Patients must have received at least standard doses of radiation (i.e., greater than 54 Gy).
Surgery/biopsy - Patients must be more than 2 weeks from any neurosurgical procedure and cleared by the Principal Investigator before undergoing CED.
Radiation - Patients must be more than 4 weeks from last fraction of radiation to the target site
Chemotherapy - Patients must not be on concurrent chemotherapy. The last dose of chemotherapy must be greater than 2 weeks prior to CED and the patient must have recovered from any toxic effects of prior therapy (to less than Grade 2 or baseline).
Biologic therapy - Patients must be greater than 7 days from biologic therapy.
Investigational therapy - Patients must be greater than 30 days from any investigational therapy.
Patients must be healthy enough to tolerate surgery and general anesthesia in the opinion of the primary investigator. This includes, but is not limited to:
Adequate baseline organ function, including an age-adjusted normal serum creatinine OR a creatinine clearance greater or equal to 60 mL/min/1.73m(2), total bilirubin less than 2 times the upper limit of normal (ULN) and direct bilirubin within normal limits. Patients with elevated SGPT (up to 5 time ULN) will be eligible if the elevation is attributed to steroid treatment.
If neurological deficits are present, they must be stable for at least 1 week prior to registration.
Patients must be able to undergo MR-imaging with gadolinium-based contrast administration (e.g. no ferrous-containing implants, no pacemakers, no allergy to contrast, etc).
All patients or their legal guardians must sign a document of informed consent indicating their
understanding of the investigational nature and the potential risks associated with this study.
When appropriate, pediatric patients will be included in all discussions in order to obtain verbal and written assent.

Patients with an uncorrectable bleeding disorder
Patients with multifocal or leptomeningeal disease
Patients with signs of impending herniation or an acute intratumoral hemorrhage
