Summary

This trial is testing a new way to treat brain tumors in children and young adults by engineering their own T cells to attack the tumor cells.

Who is the study for?
This trial is for children and young adults aged 1 to 26 with recurrent or refractory HER2-positive CNS tumors who have no standard therapy options left. They must have a CNS catheter in place, a life expectancy of at least 8 weeks, recovered from previous treatments, stable or decreasing steroid use, good organ function and lab values, not be pregnant or breastfeeding, and agree to use contraception.
What is being tested?
The study tests HER2-specific CAR T cell therapy delivered through an indwelling CNS catheter over two courses. Each course involves weekly doses for three weeks followed by one week off. The treatment aims to allow engineered T cells to directly interact with tumor cells in the brain.
What are the potential side effects?
Potential side effects may include reactions related to immune response such as inflammation around the site of infusion or within the central nervous system, general discomforts like fatigue or fever due to immune activation, and possible complications from having an indwelling catheter.

Treatment Details

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
Establish the feasibility, defined by the ability to produce and administer CAR T cell product, of HER2-specific CAR T cell product infusions delivered by a central nervous system (CNS) catheter into the tumor resection cavity or ventricular system
Establish the safety, defined by the adverse events, of HER2-specific CAR T cell infusions delivered by a central nervous system (CNS) catheter into the tumor resection cavity or ventricular system
Secondary study objectives
Assess the distribution of CNS-delivered HER2-specific CAR T cells within the cerebrospinal fluid (CSF) and peripheral blood
Disease
Assessment of whether HER2 expression changes in relapsed CNS tumors that were HER2 positive prior to treatment with CAR T cells
Other study objectives
Analysis of CSF for biomarkers of anti-tumor CAR T cell functional activity

Awards & Highlights

No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.

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 Intervention: HER2-specific chimeric antigen receptor (CAR) T cell
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 Intervention: HER2-specific chimeric antigen receptor (CAR) T cell
