A Phase I Trial Anti-CC Chemokine Receptor 4 Chimeric Antigen Receptor T Cells (CCR4 CAR T Cells) for CCR4 Expressing T-cell Malignancies Including Peripheral T-cell Non-Hodgkin Lymphoma (PTCL) and Cutaneous T-cell Non-Hodgkin Lymphoma (CTCL)

Study Summary

Background: Chemokine receptor 4 (CCR4) is a protein that is found on the surface of certain T-cell lymphoma cells and is common in mature T-cell cancers. White blood cells can be changed with molecules called anti-CCR4 to express a chimeric antigen receptors (CAR), which is a molecule that directs a white blood cell to attack other cells. The CAR in this study attacks the CCR4 protein found on your T-cell lymphoma. This type if therapy is called gene therapy. Gene therapy involves a person s own white blood cells modified to target cancer cells. More research is needed to find out if gene therapy can treat T-cell cancers and do it safely. Objective: To test safety of giving people with certain mature T-cell lymphomas their own white blood cells modified with anti-CCR-4 CAR. Eligibility: People aged 18 and older with certain mature T-cell lymphomas that have not responded to or have come back after treatment. They must have a T-cell lymphoma that has CCR4 on the surface of the cancer cells. Design: Participants will be screened. They will have a medical history and physical exam. Tests of blood, urine, and heart and lung function will be done. Participants will have tests: Computed tomography (CT), positron emission tomography (PET), and magnetic resonance imaging scans: They will lie on a table that slides into a donut-shaped machine or a tube. Pictures of the inside of the body will be taken. Before the PET scan, they will get an injection of radioactive fluid in a vein in the arm. Before the MRI, they may get a contrast dye injected through a vein (IV) in the arm. A biopsy of the tumor may be taken. A bone marrow sample may be taken from the hip: The area will be numbed and a large needle inserted through the skin. Leukapheresis will be done to obtain T-cells that will be genetically modified to express anti-CCR4 CARs on T-cells: Blood is drawn through an IV in one arm, circulated through a machine, and then returned through an IV in the other arm.
