What You Need to Know Before You Apply

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.

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. ^{1 2 3 4 5}

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. ^{1 3 4 5 6}

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. ^{1 2 3 4 6}

Are You a Good Fit for This Trial?

This trial is for patients with leptomeningeal disease from glioblastoma, ependymoma, or medulloblastoma. They must have a life expectancy of at least 8 weeks, be able to tolerate certain medical procedures and medications, not require dialysis or supplemental oxygen, and agree to use birth control. Those with other active cancers or infections like hepatitis B/C or HIV can't join.

Inclusion Criteria

I am not pregnant or will use birth control during and after the study.

My shunt valve is programmable and can be turned off for 48 hours.

Exclusion Criteria

I am willing to pause my current cancer treatments for the study.

Prospective participants who, in the opinion of the Investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)

You have a condition where your immune system attacks your own body.

Published Research Related to This Trial

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.

The YYB-103 CAR T cells demonstrated selective targeting and toxicity against malignant glioma cells expressing IL13Rα2, while sparing cells that express IL13Rα1, indicating a promising therapeutic approach for treating glioblastoma.

Both intravenous and intracerebroventricular administration of YYB-103 CAR T cells significantly reduced tumor volume and improved survival in mouse models, suggesting effective delivery across the blood-brain barrier and potential for clinical application in patients with recurrent glioblastoma.

A patient with recurrent multifocal glioblastoma treated with IL13Rα2-targeted CAR T cells showed no severe toxic effects (grade 3 or higher) after multiple infusions over 220 days, indicating a favorable safety profile for this therapy.

The treatment resulted in significant tumor regression in both intracranial and spinal tumors, with a sustained clinical response lasting 7.5 months, alongside increased cytokine and immune cell levels in the cerebrospinal fluid, suggesting effective immune activation against the tumor.

The study developed four CAR T cells using IL13 muteins and found that these cells effectively recognized and killed glioblastoma cells expressing IL13Rα1 and IL13Rα2, demonstrating their potential for targeted immunotherapy.

Among the CAR T cells tested, only those with the E13K amino acid substitution showed significant anti-tumor activity in vivo, leading to improved survival in treated animals, highlighting the importance of specific modifications in CAR design.
