I. To establish the safety and relative efficacy of CAR.CD19-CD28-zeta-2A-iCasp9-IL15-transduced cord blood natural killer (CB-NK) cells in patients with B cell non-Hodgkin lymphoma (NHL) undergoing high dose chemotherapy and autologous stem cell transplantation.
I. To estimate the relapse-free survival (RFS). II. To estimate the overall survival (OS). III. To quantify the persistence of infused CAR.CD19-CD28-zeta-2A-iCasp9-IL15-transduced CB-NK cells in the recipient.
OUTLINE: This is a phase I, dose-escalation study of CAR.CD19-CD28-zeta-2A-iCasp9-IL15-transduced CB-NK cells followed by a phase II study.
Participants receive rituximab intravenously (IV) over 3 hours on days -14 and -8, carmustine IV over 2 hours on day -13, etoposide IV over 3 hours twice daily (BID) on days -12 to -9, cytarabine IV over 1 hour BID on days -12 to -9, melphalan IV over 30 minutes on day -8, CAR.CD19-CD28-zeta-2A-iCasp9-IL15-transduced CB-NK cells IV over 1 hour on day -5. Participants undergo autologous stem cell transplantation (ASCT) on day 0. Beginning day 0, participants receive filgrastim subcutaneously (SC) once daily (QD) until evidence of an absolute neutrophil count (ANC) of 0.5 x 10^9/L per 3 consecutive days.
After completion of study treatment, participants are followed for up to 15 years.

Experimental: Treatment (CAR transduced CB-NK cells, chemotherapy, ASCT)
Participants receive rituximab IV over 3 hours on days -14 and -8, carmustine IV over 2 hours on day -13, etoposide IV over 3 hours BID on days -12 to -9, cytarabine IV over 1 hour BID on days -12 to -9, melphalan IV over 30 minutes on day -8, CAR.CD19-CD28-zeta-2A-iCasp9-IL15-transduced CB-NK cells IV over 1 hour on day -5. Participants undergo ASCT on day 0. Beginning day 0, participants receive filgrastim SC QD until evidence of an ANC of 0.5 x 10^9/L per 3 consecutive days.

Biological: Umbilical Cord Blood-derived Natural Killer Cells
Given CAR.CD19-CD28-zeta-2A-iCasp9-IL15-transduced CB-NK cells IV
- Incidence of adverse events defined as graft failure, grade 3, 4 graft versus host disease, grade 3,4 cytokine release syndrome, grade 3, 4, neuro-toxicity, or death from any cause [ Time Frame: Up to 30 days within natural killer (NK) cell infusion ]Frequencies of toxicity will be summarized by dose. The relationships between toxicity and efficacy as functions of dose and other covariates will be assessed by fitting Bayesian regression models.
- Complete response (CR) or partial response (PR) [ Time Frame: At day 30 post NK cell infusion ]Efficacy is defined as the patient being alive and in CR or PR at day 30 post NK cell infusion. Frequencies of efficacy will be summarized by dose. The relationships between toxicity and efficacy as functions of dose and other covariates will be assessed by fitting Bayesian regression models.
- Progression-free survival (PFS) time [ Time Frame: At day 100 ]Unadjusted distributions of the time-to-event outcome PFS will be estimated using the method of Kaplan and Meier. The relationship of PFS to prognostic covariates and NK cell dose level will be evaluated by Bayesian piecewise exponential survival regression.
- Overall survival (OS) time [ Time Frame: At day 100 ]Unadjusted distributions of the time-to-event outcome OS will be estimated using the method of Kaplan and Meier. The relationship of OS to prognostic covariates and NK cell dose level will be evaluated by Bayesian piecewise exponential survival regression.
- Response status [ Time Frame: 16 weeks ]Participants have a bone marrow aspiration and/or biopsy to check the status of the disease.
- Number of chimeric antigen receptor (CAR) NK cells in blood by flow cytometry [ Time Frame: Up to 16 weeks post CAR NK cell infusion ]The number of CAR NK cells in blood by flow cytometry will be measured on days 3, 7, 14, 21, and at 4 weeks, 8 weeks, 12 weeks, and 16 weeks post CAR NK cell infusion. In addition to preliminary graphical analysis to assess possible patterns over time Bayesian longitudinal regression using a generalized Poisson regression model for the count at each time point as a function of patient baseline covariates, and random latent patient effects to induce within-patient correlation among each patient's vector of CAR NK cell counts.
