Trial Summary

What is the purpose of this trial?

This phase I trial investigates the side effects of brain tumor-specific immune cells (IL13Ralpha2-CAR T cells) in treating patients with leptomeningeal disease from glioblastoma, ependymoma, or medulloblastoma. Immune cells are part of the immune system and help the body fight infections and other diseases. Immune cells can be engineered to destroy brain tumor cells in the laboratory. IL13Ralpha2-CAR T cells is brain tumor specific and can enter and express its genes in immune cells. Giving IL13Ralpha2-CAR T cells may better recognize and destroy brain tumor cells in patients with leptomeningeal disease from glioblastoma, ependymoma or medulloblastoma.

Do I need to stop my current medications for the trial?

Yes, you will need to stop taking chemotherapy, endocrine therapy, and radiation one week before and during the first 4 cycles of the study.

What data supports the effectiveness of the treatment IL13Ralpha2-CAR T cells for glioblastoma?

Research shows that IL13Ralpha2-CAR T cells can specifically target and kill glioblastoma cells that have a certain marker (IL13Ralpha2) without affecting normal brain cells. In a study, a patient with glioblastoma experienced tumor shrinkage after receiving this treatment, and the positive effects lasted for several months.12345

Is CAR T-Cell Therapy targeting IL13Rα2 safe for humans?

In a clinical trial, CAR T-Cell Therapy targeting IL13Rα2 was given to a patient with glioblastoma, and no severe toxic effects were observed. This suggests that the treatment may be generally safe in humans.13456

What makes IL13Ralpha2-CAR T-cell therapy unique for treating glioblastoma?

IL13Ralpha2-CAR T-cell therapy is unique because it specifically targets the IL13Rα2 protein, which is highly expressed in glioblastoma but not in normal brain tissue, reducing the risk of harming healthy cells. This therapy involves genetically modifying T cells to recognize and attack glioblastoma cells, offering a promising approach for patients with this aggressive cancer.23456

Findings from Research

The study demonstrates a novel immunotherapy approach targeting malignant glioma by using cytotoxic T lymphocytes (CTL) that are specifically induced to recognize the IL-13 receptor alpha2 (IL-13Ralpha2) epitope, which is unique to glioma cells.
Induced CTLs showed effective lysis of glioma cells expressing the IL-13Ralpha2(345-353) peptide, indicating potential for targeted treatment in HLA-A2 patients, while their activity was inhibited by anti-HLA class I antibodies, highlighting the mechanism of action involved.

A specific CTL epitope derived from the IL-13 receptor alpha2-chain (IL-13Ralpha2) was identified, which is overexpressed in glioblastoma multiforme, and can stimulate CD8+ T cells to produce IFN-gamma and kill glioma cells.
The IL-13Ralpha(345-354) peptide demonstrated effective lytic activity against glioma cell lines, suggesting its potential use in peptide-based vaccines for glioma treatment and as a marker for T-cell immune responses in patients.

IL13Rα2-specific CAR T cells, designed to target glioblastoma without affecting normal brain tissue, demonstrated effective recognition and destruction of IL13Rα2-positive cancer cells without cross-reactivity to IL13Rα1.
In vivo studies showed that CAR T cells with short spacer regions and specific endodomains significantly improved survival in mice with glioma, indicating their potential as a promising treatment for glioblastoma and similar cancers.
