Summary

This trial is testing a new therapy for children and young adults with brain tumors that involves genetically modifying the patient's own T cells to attack the tumor cells.

Who is the study for?
This trial is for young people aged 15-26 with recurrent or refractory EGFR-positive CNS tumors who have a life expectancy of at least 8 weeks. They must be able to undergo apheresis, have recovered from previous treatments, and their organs must function well. Participants need an implanted CNS reservoir catheter and agree to use effective contraception.
What is being tested?
The study tests the safety and effectiveness of delivering EGFR806-specific CAR T cells directly into the brain or spinal fluid via a catheter in children and young adults with certain brain tumors. It aims to see how these cells distribute within the body, their impact on tumor response, and potential biomarkers.
What are the potential side effects?
Potential side effects may include reactions related to immune cell infusion such as fever, fatigue, headache, or neurological symptoms like confusion. Since this is an investigational therapy targeting specific cancer cells in the brain, risks are monitored closely.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Feasibility: The number of successfully manufactured and infused EGFR806-specific CAR T cell product
Safety: any adverse events associated with one or multiple EGFR806-specific CAR T cell product infusions will be assessed by CTCAE v5.0.
Secondary outcome measures
Cerebrospinal Fluid
Disease response: Assessment of disease response of EGFR-expressing refractory or recurrent central nervous system (CNS) tumors to EGFR806 specific CAR T cell therapy delivered directly into the CNS by cytology and radiology criteria.
Expression of target epitope: assessment of whether EGFR expression changes in relapsed CNS tumors that were EGFR positive prior to treatment with CAR T cells via immunohistochemistry on resected tissue samples.
Other outcome measures
Quantitative biomarker assessment of anti tumor CAR T cell functional activity

Trial Design

2Treatment groups
Experimental Treatment
Group I: ARM B (Ventricular System Infusion)Experimental Treatment1 Intervention
Patients with either infratentorial tumors or leptomeningeal tumors for which the CAR T cells will be delivered into the fourth ventricle or lateral ventricle, respectively
Group II: ARM A (Tumor Cavity Infusion)Experimental Treatment1 Intervention
Patients with supratentorial tumors for which CAR T cells will be delivered into the tumor resection cavity
