Intracerebroventricular Administration of CD19-CAR T Cells (CD19CAR-CD28-CD3zeta-EGFRt-expressing Tcm-enriched T-lymphocytes) for the Treatment of Primary Central Nervous System Lymphoma

• Status: Not yet recruiting

Summary

This phase I trial tests the safety, side effects, and best dose of intracerebroventricularly (ICV) administered CD19-chimeric antigen receptor (CAR) T cells in treating patients with primary central nervous system (CNS) lymphoma. CAR T cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein, CD19, on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. ICV is an injection technique that delivers the CD19-CAR T cells directly into the cerebrospinal fluid (which flows in and around the hollow spaces of the brain and spinal cord, and the thin layers of tissue that cover and protect the brain and spinal cord) in the brain, through a surgically placed catheter. Giving CD19-CAR T cells ICV may be more effective at treating patients with primary CNS lymphoma than giving them via other methods.
