Brief Summary:
This phase I trial studies the side effects and best dose of CD19/CD20 chimeric antigen receptor (CAR) T-cells when given together with chemotherapy, and to see how effective they are in treating patients with non-Hodgkin's B-cell lymphoma or chronic lymphocytic leukemia that has come back (recurrent) or has not responded to treatment (refractory). In CAR-T cell therapy, a patient's white blood cells (T cells) are changed in the laboratory to produce an engineered receptor that allows the T cell to recognize and respond to CD19 and CD20 proteins. CD19 and CD20 are commonly found on non-Hodgkin?s B-cell lymphoma and chronic lymphocytic leukemia cells. Chemotherapy drugs such as fludarabine phosphate and cyclophosphamide can control cancer cells by killing them, by preventing their growth, or by stopping them from spreading. Combining CD19/CD20 CAR-T cells and chemotherapy may help treat patients with recurrent or refractory B-cell lymphoma or chronic lymphocytic leukemia.

Primary Outcome Measures :
- Incidence of adverse events [ Time Frame: Up to 28 days from infusion ]Will be assessed according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, with the exception of cytokine release syndrome (CRS), which will be graded on the American Society for Transplantation and Cellular Therapy (ASTCT) Consensus Grading for CRS scale. Simple descriptive statistics will be used to summarize toxicities observed after each transgenic T-cell infusion in terms of type (organ affected or laboratory determination such as absolute neutrophil count), severity (by CTCAE toxicity table) and minimum or maximum values for laboratory measures, time of onset, duration, and reversibility or outcome. Tables will be created to summarize these toxicities and side effects. Adverse events will be tabulated by treatment group and will include the number of patients for whom the event occurred, the rate of occurrence, and the severity and relationship to study drug.
- Dose-limiting toxicities [ Time Frame: Up to 28 days from infusion ]Will be assessed per CTCAE version 5.0 with the exception of CRS as mentioned above.
Secondary Outcome Measures :
- Clinical response [ Time Frame: Up to 15 years ]Descriptive statistics including simple summary measures and plots appropriate for longitudinal data will be used.
- Duration of remission [ Time Frame: Time from complete remission (CR)/partial remission (PR) measurement criteria are first met until the first date that recurrent or progressive disease is objectively documented, or until death, assessed up to 15 years ]Descriptive statistics including simple summary measures and plots appropriate for longitudinal data will be used. Will also be summarized descriptively (mean, standard deviation, median, first and third quartiles, minimum, maximum). Figures showing the Kaplan-Meier estimates will also be presented.
- Objective response rate (ORR) [ Time Frame: Up to 15 years ]Descriptive statistics including simple summary measures and plots appropriate for longitudinal data will be used. ORR and the individual rate for CR and PR will be summarized with the frequency count and the percentage of subjects in each category, along with a 2-sided 95% exact confidence interval.
- Progression-free survival [ Time Frame: From time of study entry to documentation of objective disease progression or death due to any cause assessed up to 15 years ]Descriptive statistics including simple summary measures and plots appropriate for longitudinal data will be used. Will also be summarized descriptively (mean, standard deviation, median, first and third quartiles, minimum, maximum). Figures showing the Kaplan-Meier estimates will also be presented.
- Overall survival (OS) [ Time Frame: From date of enrollment until death, assessed up to 15 years ]Descriptive statistics including simple summary measures and plots appropriate for longitudinal data will be used. Will be summarized with figures using the Kaplan-Meier method. The Kaplan-Meier estimates for the 1-year OS (rates and the 2-sided 95% confidence interval of the rates using the Greenwood?s formula will be reported. Will also be summarized descriptively (mean, standard deviation, median, first and third quartiles, minimum, maximum).
- Chimeric antigen receptor (CAR) T-cell (T) 19/20 bispecific transgenic T-cell persistence [ Time Frame: Up to 5 years post-infusion ]Descriptive statistics of T-cell counts over time, including simple summary measures and plots appropriate for longitudinal data will be used.
- Frequency of T cell phenotypic markers on CART19/20 cells using flow cytometry [ Time Frame: Up to 5 years post-infusion ]The frequency of CART19/20 cell properties will be assessed using flow cytometry to indicate the % and/or total number of CART19/20 cells expressing critical markers, for example CD3 (cluster of differentiation 3), CD4 (cluster of differentiation 4), and CD8 (cluster of differentiation 8), to determine correlations between CART19/20 properties, treatment efficacy, and CART19/20 cell persistence.
- Duration of B-cell aplasia following CART19/20 infusion. [ Time Frame: Up to 2 years post-infusion ]The duration of time patients experience B-cell aplasia (<3% of lymphocytes in the peripheral blood expressing either CD19 or CD20, measured with immunohistochemistry (IHC) and/or flow cytometry) following infusion of CART19/20 cells will be determined.
Other Outcome Measures:
- Analysis of proteins/cytokines (c-reactive protein (CRP), interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α), and interferon-gamma (IFN-γ)) concentration in peripheral blood following CART19/20 infusion. [ Time Frame: Up to 30 days post-infusion ]The cytokine levels in patients who receive CAR therapies will be monitored to help clarify the complex relationship between CRS severity, toxicity, T-cell survival, and disease eradication. Cytokine levels will be quantified in patients exhibiting any > grade-2 CRS. Cytokine levels in patients who do not exhibit CRS, or exhibit =< grade-2 CRS, will be quantified at the discretion of the investigator. The concentration in blood of each protein will be measured (CRP: mg/dL; IL-6, TNF-α, IFN-γ: pg/mL).

All female patients with reproductive potential must have a negative pregnancy test (serum/urine) at screening and again within 14 days from starting the conditioning chemotherapy. The definition of effective contraception will be based on the judgment of the study investigators. Patients who are breastfeeding are not allowed on this study
