What You Need to Know Before You Apply

What is the purpose of this trial?

This study is designed as a single arm open label Phase I, 3x3, multicenter study of CD4-directed chimeric antigen receptor engineered T-cells (CD4CAR) in patients with relapsed or refractory T-cell leukemia and lymphoma. Specifically, the study will evaluate the safety and feasibility of CD4CAR T-cells. Funding Source - FDA OOPD

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

The trial does not specify if you need to stop all current medications, but you cannot use systemic glucocorticoids above replacement doses unless part of standard care. If you are on corticosteroids, you must be off all but adrenal replacement doses 3 days before the CD4CAR infusion.

Is CAR T-cell therapy safe for humans?

CAR T-cell therapy, used for treating certain types of leukemia and lymphoma, can have serious side effects like cytokine release syndrome (a severe immune reaction) and neurotoxicity (nerve damage). Patients are usually monitored in the hospital for at least a week to manage these risks. ^{1 2 3 4 5}

What makes CD4CAR T-cell therapy unique for treating leukemia and lymphoma?

CD4CAR T-cell therapy is unique because it uses specially engineered T cells to target and destroy CD4-expressing cancer cells, offering a new approach for aggressive lymphomas that lack effective standard treatments. This therapy is a form of gene and cellular therapy that can potentially provide lasting remissions by redirecting the immune system to attack cancer cells. ^{6 7 8 9 10}

What data supports the effectiveness of the treatment CD4CAR T cells for leukemia and lymphoma?

Research shows that CD4CAR T cells can effectively target and eliminate CD4+ cancer cells in laboratory settings and animal models, leading to reduced tumor growth and prolonged survival in mice with T-cell lymphoma. This suggests potential effectiveness for treating similar human cancers. ^{6 7 11 12 13}

Published Research Related to This Trial

CD4-specific chimeric antigen receptor (CAR) engineered T cells (CD4CART) demonstrated strong cytotoxic effects against CD4+ T cell lymphoma in both laboratory tests and in live mice, indicating their potential as an effective treatment.

The transfer of CD4CART cells significantly reduced tumor growth and improved survival rates in mice with T cell lymphoma compared to control treatments, suggesting a promising therapeutic approach for this type of cancer.

CD4-Targeted T Cells Rapidly Induce Remissions in Mice with T Cell Lymphoma. Cheng, J., Chen, G., Lv, H., et al.[2022]

The study developed a CAR (CD4CAR) that enables CD8+ T cells to target and eliminate CD4+ T-cell lymphomas, showing effectiveness in both laboratory and patient-derived samples.

In mouse models of aggressive T-cell lymphoma, CD4CAR T cells not only suppressed tumor growth but also significantly extended survival, suggesting their potential as a new treatment option for patients with peripheral T-cell lymphomas.

Preclinical targeting of human T-cell malignancies using CD4-specific chimeric antigen receptor (CAR)-engineered T cells. Pinz, K., Liu, H., Golightly, M., et al.[2018]

In a Phase I trial involving 43 pediatric and young adult patients with leukemia, initial treatment failures were linked to poor CAR T cell expansion and rapid loss of functional CAR T cells after infusion.

For patients who achieved remission, the durability of that remission was associated with higher levels of TNF-α-secreting CAR CD8+ T cells and sufficient CD19 antigen levels at the time of treatment, suggesting these factors could help predict treatment success.
