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).

Outcome Measures
Primary Outcomes (1)
Dose-limiting Toxicities (DLT) Rate
Will be graded by Common Terminology Criteria for Adverse Events version 4.0. Observed DLT rates will be summarized based on the DLT-Evaluable analysis set. Outcome reported as count of participants in each arm who experienced a DLT.
Up to 28 days
Secondary Outcomes (4)
Complete Remission
Up to 15 years
Progression-free Survival (PFS)
Duration from study enrollment to progression or death due to any cause (whichever comes first), assessed up to 15 years
Overall Survival (OS)
Duration from study enrollment to death due to any cause, assessed up to 15 years
Incidence of Adverse Events
Up to 15 years
Study Arms (1)
Treatment (CD20-specific CAR T cell, chemotherapy)
EXPERIMENTALPatients 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 IV over 20-30 minutes.
Interventions
Given CD20 CAR T cell IV
Given IV

Eligibility Criteria
You may qualify if:
- 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:
- Primary CNS lymphoma:
- Progressive disease after 3 cycles or an inadequate response after at least 4 cycles of a high-dose methotrexate (MTX) containing regimen in the opinion of the treating physician, OR
- Not eligible for MTX therapy due to commodities or tolerance issues per treating physician OR
- Recurrent disease after an initial response to MTX-based treatment
- Secondary CNS lymphoma:
- An inadequate rtesponse to at least 2 cycles of a MTX containing regimen, OR
- Recurrent disease after an initial response to MTX-based treatment
- +28 more criteria
You may not qualify if:
- Active autoimmune disease requiring systemic immunosuppressive therapy
- Patients requiring corticosteroid therapy at a dose of 15 mg or more per day of prednisone or the equivalent; pulsed corticosteroid dose for disease control is acceptable
- Patients who are human immunodeficiency virus (HIV) seropositive
- Women who are pregnant or breastfeeding
- Significant cardiovascular diseases within the past 6 months including uncontrolled congestive heart failure (\> New York Heart Association \[NYHA\] class II), myocardial infarction, unstable angina, or uncontrolled arrhythmia
- History of severe immediate hypersensitivity reaction to cyclophosphamide or fludarabine
- History or presence of clinically relevant non-lymphoma central nervous system pathology, including seizures that are uncontrolled on anticonvulsant therapy (\>= 1 seizure in the last year), paresis, aphasia, stroke, severe brain injuries, dementia, Parkinson disease, cerebellar disease, or psychosis
- Treatment with any investigational agent on a different clinical trial within 4 weeks prior to enrollment, unless the patient is documented to be unresponsive to the therapy and at least 3 half-lives have elapsed prior to enrollment
- Treatment with any anti-CD19 or anti-CD20 antibody or antibody-drug conjugate therapy within 4 weeks before enrollment
- Previous treatment with CD19-targeted CAR T cells that has resulted in ongoing B cell aplasia at the time of enrollment; patients that demonstrate recovery of normal B cells (\>= 20 B cells/ul) by flow cytometry at any point 28 days or later after CD19 CAR T cell infusion will be considered to have functional loss of CD19 CAR T cells and are potentially eligible
- Presence of active acute or chronic graft versus host disease (GVHD)
- Uncontrolled active infection (bacterial, fungal, viral, mycobacterial) not responding to treatment with intravenous antibiotics, antiviral or antifungal agents
- Patients with concurrent known additional malignancy that is progressing and/or requires active treatment; exceptions include squamous or basal cell carcinoma of the skin and low grade prostate carcinoma (Gleason grade =\< 6). Maintenance anti-hormone therapies for breast or prostate cancers are allowed and are not considered active treatment
- Patients with blood or platelet transfusion within 1 week prior to signing Consent A, or with platelets \< 50,000/mm\^3, neutrophils \< 750/mm\^3, or hemoglobin \< 8.5 g/dL, unless the cytopenias are considered by the treating physician to be largely due to marrow involvement by lymphoma
