CAR.CD19-CD28-zeta-2A-iCasp9-IL15-Transduced Cord Blood NK Cells, High-Dose Chemotherapy, and Stem Cell Transplant in Treating Participants With B-cell Lymphoma

Overview

This phase I/II trial studies the side effects and best dose of chimeric antigen receptor (CAR).CD19-CD28-zeta-2A-iCasp9-IL15-transduced cord blood NK cells when given together with high-dose chemotherapy and stem cell transplant and to see how well they work in treating participants with B-cell lymphoma. Cord blood-derived CAR-NK cells may react against the B-cell lymphoma cells in the body, which may help to control the disease. Giving chemotherapy before a stem cell transplant may help kill any cancer cells that are in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy.

Detailed Description

PRIMARY OBJECTIVES: 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. SECONDARY OBJECTIVES: 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.

Clinical Trial Outcome Measures

Primary Measures

  • 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.

Secondary Measures

  • 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.
