This phase II clinical trial studies how well CD19CAR-CD3zeta-4-1BB-expressing autologous T-lymphocytes (CART-19 cells) work in treating patients with chemotherapy recurrent or refractory B cell non-Hodgkin lymphoma. This type of non-Hodgkin lymphoma involves a kind of white cell (or lymphocyte) called the B-cell. T-cells are modified through gene transfer using a type of virus called a lentiviral vector to deliver the genetic material called CART-19 into a patient's T-cells. These modified cells are called CART-19 T-cells. The CART-19 T-cells will be able to identify and possibly kill cancerous B-cells and may help the body build an effective immune response to kill cancer cells.

PRIMARY OBJECTIVES:
I. To estimate the efficacy of a single target dose of 1-5 x10^8 CART-19 cells for patients with advanced B cell non-Hodgkin’s lymphoma (NHL); describe overall response rate for patients with NHL.
SECONDARY OBJECTIVES:
I. Determine persistence, trafficking and function of CART-19 cells.
II. Determine the effects of CART-19 infusion on B cells and CD19 expression in vivo.
III. Evaluate impact of CART-19 treatment on systemic soluble immune factors in patients.
IV. Determine if cellular or humoral host immunity develops against CART-19 cells.
V. Characterize the relative subsets of CART-19 T cells (central memory T cells [Tcm], effector memory T cells [Tem], and regulatory T cells [Treg]).
VI. Evaluate minimal residual disease (MRD) using molecular technologies.
VII. Describe overall response rate (ORR) for each individual histology (minimum n = 8), complete remission (CR), complete remission unconfirmed (CRu) and partial remission (PR) rate.
VIII. Describe overall survival (OS) and progression-free survival (PFS) for all patients.
IX. Describe duration of response (DOR) for responding patients.
X. Assess the safety and tolerability of CART-19 in NHL subjects by recording the frequency and severity of adverse events reporting, including but not limited to, estimating the frequency of cytokine release syndrome (CRS) and macrophage activation syndrome (MAS).
XI. Determine the dose manufacturing feasibility.
XII. Follow subjects infused with less than protocol-specified target dose.
OUTLINE:
Patients receive CART-19 cells intravenously (IV) on day 0.
After completion of study treatment, patients are followed up periodically for up to 15 years.
