Brief summary

This phase I trial investigates the side effects and best dose of CD19 positive (+) specific CAR-T cells in treating patients with CD19+ lymphoid malignancies, such as acute lymphoblastic leukemia, non-Hodgkin lymphoma, small lymphocytic lymphoma, or chronic lymphocytic lymphoma. Sometimes researchers change the genetic material in the cells of a patient's T cells using a process called gene transfer. Researchers then inject the changed T-cells into the patient's body. Receiving the T-cell infusion may help to control the disease.

Detailed description

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.

Design outcomes

Primary

MeasureTime frameDescription
