I. To estimate the maximum tolerated dose (MTD) of adoptive cellular immunotherapy using ex vivo transduced and expanded autologous T cells expressing a third (3rd)-generation fully human CD20-specific chimeric antigen receptor (CAR) in patients with relapsed or refractory CD20+ B-cell non-Hodgkin lymphoma (B-NHL).
I. To evaluate the safety and toxicity associated with CD20 CAR T cell infusions.
II. To evaluate preliminary antitumor activity of adoptively transferred T cells in patients with measurable tumor burden prior to treatment as measured by overall response rate (ORR) and complete remission (CR) rate.
III. To evaluate progression-free survival (PFS) and overall survival (OS) among patients treated with adoptively transferred CD20-specific T cells.
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.
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.

Experimental: Treatment (CD20-specific CAR T cell, chemotherapy)
Patients undergo leukapheresis and may receive treatment after if needed for disease control. Patients then receive cyclophosphamide IV. Patients may also receive fludarabine IV. After 36-96 hours, patients receive CD20-specific CAR T cell infusion.
Biological: Chimeric Antigen Receptor T-Cell Therapy
Given CD20 CAR T cell IV
Other Name: Fluradosa
Other: Laboratory Biomarker Analysis
Drug: Fludarabine Phosphate
- Dose-limiting toxicity [ Time Frame: Up to 28 days ]Will be graded by Common Terminology Criteria for Adverse Events version 4.0.
- Complete remission [ Time Frame: Up to 15 years ]Will be assessed based on the Lugano criteria.
- Progression-free survival (PFS) [ Time Frame: Duration from study enrollment to progression or death due to any cause (whichever comes first), assessed up to 15 years ]A Cox proportional hazards model will be used to evaluate PFS.
- Overall survival (OS) [ Time Frame: Duration from study enrollment to death due to any cause, assessed up to 15 years ]A Cox proportional hazards model will be used to evaluate OS.
- Incidence of adverse events [ Time Frame: Up to 15 years ]Will be assessed by National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0.
