This phase I trial studies the side effects and best dose of autologous anti-CD19 CAR-CD3zeta-4-1BB-expressing T-cells (antiCD9 chimeric antigen receptor T-cells) when given together with chemotherapy in treating patients with CD19 positive non-Hodgkin lymphoma that has come back (recurrent) or that does not respond to treatment (refractory). Therapy with antiCD9 chimeric antigen receptor T-cells works by removing T cells from the blood and modifying them to be able to target cancer. Drugs used in chemotherapy, such as cyclophosphamide and fludarabine phosphate, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading, and may work to suppress the immune system and allow antiCD9 chimeric antigen receptor T-cells to work better. Giving antiCD9 chimeric antigen receptor T-cells and chemotherapy may work better in treating patients with non-Hodgkin lymphoma.

PRIMARY OBJECTIVE:
I. To determine the safety of the treatment of relapsed or refractory B cell lymphomas with chimeric antigen receptor T cells targeting CD19 and to find the recommended phase II dose for this cellular therapy.
SECONDARY OBJECTIVES:
I. To describe the safety profile of the infusion of chimeric antigen receptor (CAR)-T cells targeting CD19.
II. To describe the toxicities related to infusion of CAR-T cells targeting CD19.
III. To describe the overall response rate and complete response rate of relapsed B cell malignancies treated with CAR-T cells targeting CD19.
CORRELATIVE OBJECTIVES:
I. To describe the persistence of anti-CD19 CAR-T cells, measured by flow cytometry and quantitative polymerase chain reaction (qPCR).
II. To describe the T cell subpopulations of the anti-CD19 CAR-T cell product before infusion.
III. To describe the changes in anti-CD19 CAR-T cells after infusion and their correlation with disease response and adverse events.
IV. To investigate the correlation between changes in cytokine plasma concentrations and changes in anti-CD19 CAR-T cell subpopulations over time and with changes in conditioning regimen.
OUTLINE: This is a dose-escalation study of autologous anti-CD19 CAR-CD3zeta-4-1BB-expressing T-cells.
LYMPHODEPLETION CHEMOTHERAPY: Patients receive cyclophosphamide intravenously (IV) over 60 minutes on day -6 or low-dose cyclophosphamide IV over 60 minutes on days -5 to -3, and fludarabine phosphate IV over 30 minutes on days -5 to -3 in the absence of disease progression or unacceptable toxicity.
T-CELL INFUSION: Patients receive autologous anti-CD19 CAR-CD3zeta-4-1BB-expressing T-cells via injection or IV over 5-30 minutes on day 0.
After completion of study treatment, patients are followed for 30 days, at 3, 6, and 12 months, then once a year for up to 15 years.
