A Phase I/II Study to Evaluate the Safety of Cellular Immunotherapy Using Autologous T Cells Engineered to Express a CD20-Specific Chimeric Antigen Receptor for Patients With Relapsed or Refractory B Cell Non-Hodgkin Lymphomas
Study Details
Study Description
Brief Summary
The purpose of this research is to find the best dose of genetically modified T-cells, to study the safety of this treatment, and to see how well it works in treating patients with B cell non-Hodgkin lymphoma that has come back (relapsed) or did not respond to previous treatment (refractory).
Detailed Description
OUTLINE:
This is a phase I/II dose-escalation study of CD20-specific CAR T cell therapy.
Patients undergo leukapheresis and may receive treatment after if needed for disease control. Patients then receive cyclophosphamide intravenously (IV). Patients may also receive fludarabine IV. After 36-96 hours, patients receive CD20-specific CAR T cell infusion IV over 20-30 minutes.
Patients will be actively participating in the study for approximately 15 months. The total time includes the time for the T cells to be made, the T cell infusion, and for approximately 12 months after the T cell infusion is given. After completion of study treatment, patients are followed up for a minimum of 15 years.
