Non Hodgkin Lymphoma Clinical Trial
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
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).
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.
Patients must have B-cell non-Hodgkin lymphoma or chronic lymphocytic leukemia/small lymphocytic lymphoma. Eligible lymphoma subtypes include (but not limited to): mantle cell, follicular, lymphoplasmacytic, marginal zone, transformed indolent B cell lymphoma (including transformed chronic lymphoid leukemia [CLL]), or diffuse large B cell lymphoma that has relapsed after a response to at least one prior therapy regimen or is refractory to prior therapy; patients with mantle cell lymphoma must have previously been treated with a Bruton tyrosine kinase (BTK) inhibitor and have either had disease progression, intolerance, or exposure to the drug for at least 3 months; patients with CLL/SLL are eligible if they had disease progression or intolerance to BTKis and/or a BCL-2 inhibitors; they are also required to have been treated with the other agent for at least 3 months (i.e. patients with progression/intolerance to BTKi need to be treated with a BCL-2 inhibitor for at least 3 months, and patients with progression/intolerance to BCL-2 inhibitor need at least 3 months of exposure to a BTKi); patients with de novo diffuse large B-cell lymphoma (DLBCL) must meet one of the following criteria:
Biopsy-proven refractory disease after a frontline regimen containing both an anthracycline and rituximab or other anti-CD20 antibody (i.e. "primary refractory"), where any disease recurring within 6 months of completion of the regimen is considered refractory
Relapsed or refractory disease after at least one of the following:
At least 2 lines of therapy (including at least one with an anthracycline and anti-CD20 antibody)
Autologous stem cell transplant
Allogeneic stem cell transplant
Patients with large cell lymphoma transformed from indolent lymphomas are eligible if previously treated with anthracycline containing regimen for either the indolent or large cell histology
Patients with central nervous system (CNS) lymphoma need to meet one of the following criteria:

Evidence of CD20 expression by immunohistochemistry or flow cytometry on the tumor specimen obtained with the biopsy performed with screening; if the CD20 expression on the screening tumor biopsy is unclear or could not be assessed due to technical reasons, CD20 expression on a concomitant tumor specimen (such as marrow biopsy or circulating tumor cells) may be used to satisfy this requirement. For CLL and lymphoplasmacytic lymphoma/Waldenström macroglobulinemia (WM) patients, the screening tumor biopsy can we waived for clinical reasons after discussion with the study principal investigator (PI). For patients with CNS lymphoma, a screening tumor biopsy is not required and evidence of CD20 expression can be documented from the original or prior biopsies
