This phase I trial identifies the best dose and effect of patient-derived genetically modified CAR-T cells in treating patients with CD19+ advanced B-cell lymphoma or leukemia after they have received a bone marrow transplant from a related donor. CAR T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient’s blood. Then the gene for a special receptor that binds to a certain protein on the patient’s cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion. This trial aims to find out the highest dose of these special T-cells that can be given safely to leukemia and lymphoma patients and learn how and whether T cells can be rapidly made. This study also investigates how long the changed T-cells stay in the body, and if adding them to a standard bone marrow transplant can improve how patients respond to treatment. Receiving the T-cell infusion may help to control the disease.

PRIMARY OBJECTIVE:
I. To determine the safety and maximum tolerated dose (MTD) of donor-derived genetically modified, CD19-specific T cells expressing mbIL15 and HER1t using the Rapid Personalized Manufacture (RPM) process (autologous CD19-CD8-CD28-CD3zeta-chimeric antigen receptor [CAR]-mbIL15-HER1t T cells [CD19-mbIL15-CAR-T cells]) administered to patients with CD19+ advanced lymphoid malignancies who have previously received an allogeneic hematopoietic stem cell transplantation (HSCT), including haploidentical HSCT.
SECONDARY OBJECTIVES:
I. To demonstrate the feasibility of the RPM process.
II. To determine the incidence and grading of cytokine release syndrome (CRS) and neurotoxicity.
III. To determine persistence of genetically modified T cells.
IV. To determine if cetuximab can control numbers of infused T cells.
V. To screen for the development of host immune responses against the transgenes (one or more of CAR, mbIL15, HER1t).
VI. To determine cytokine profile of the patient with infused T cells.
VII. To demonstrate the homing ability of the infused T cells.
VIII. To assess disease response after T-cell infusion.
IX. To assess progression-free and overall survival.
X. To detect emergence of CD19 negative (neg) malignant B cells.
OUTLINE: This is a dose-escalation study of autologous CD19-CD8-CD28-CD3zeta-CAR-mbIL15-HER1t T cells.
CHEMOTHERAPY: Patients receive fludarabine intravenously (IV) over 1 hour and cyclophosphamide IV over 3 hours on days -5, -4, and -3 in the absence of disease progression or unacceptable toxicity.
T-CELL INFUSION: Patients receive autologous CD19-CD8-CD28-CD3zeta-CAR-mbIL15-HER1t T cells IV over 15-30 minutes on day 0.
After completion of study treatment, patients are followed up within 3 days after T-cell infusion and at 1, 2, 3, 4, 6, and 8 weeks, then at 3, 6, and 12 months, then periodically for up to 15 years.
