Brief Summary

This phase I/II trial studies the side effects and best dose of laboratory treated T cells to see how well they work in treating patients with chronic lymphocytic leukemia, non-Hodgkin lymphoma, or acute lymphoblastic leukemia that have come back or have not responded to treatment. T cells that are treated in the laboratory before being given back to the patient may make the body build an immune response to kill cancer cells.

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate the feasibility and safety of adoptive T cell therapy using ex vivo expanded autologous CD8 positive (+) and CD4+ CD19 chimeric antigen receptor (CAR)-T cells for patients with advanced CD19+ B cell malignancies.

SECONDARY OBJECTIVES:

I. To determine the duration of in vivo persistence of adoptively transferred T cells, and the phenotype of persisting T cells.

II. To determine if adoptively transferred T cells traffic to the bone marrow and function in vivo.

III. To determine if the adoptive transfer of CD19 CAR-T cells results in depletion of CD19+ B cells in vivo as a surrogate for functional activity.

IV. To determine if the adoptive transfer of CD19 CAR-T cells has antitumor activity in patients with measurable tumor burden prior to T cell transfer.

V. To determine if the adoptive transfer of CD19 CAR-T cells is associated with tumor lysis syndrome.

OUTLINE: This is a phase I, dose-escalation study of autologous CD19 CAR T-cells followed by a phase II study.

Patients receive anti-CD19-CAR lentiviral vector-transduced autologous T cells intravenously (IV) over 20-30 minutes on day 0. Treatment may be repeated in no less than 21 days with or without additional lymphodepleting chemotherapy if there is persistent disease in the absence of unacceptable toxicity.

DOSE DENSE EXPANSION COHORT: An additional cohort will receive a second anti-CD19-CAR lentiviral vector-transduced autologous T cell infusion without additional lymphodepleting chemotherapy 10-21 days after the first infusion if adequate CD19 CAR-T cells can be produced and appropriate criteria are met.

After completion of study treatment, patients are followed up for at least 15 years.

INCLUSIONS FOR CAR-T CELL THERAPY

• Patients with:

  • CLL who are beyond first remission and who have failed combination chemoimmunotherapy with regimens containing a purine analogue and anti-CD20 antibody or who were not eligible for such therapy; patients with CLL for whom ibrutinib is now standard first line therapy, must have progressed on ibrutinib; patients with fludarabine refractory disease are eligible; patients may be treated following allogeneic hematopoietic cell transplant (HCT); for the concurrent ibrutinib cohort, patients must agree to continue on or be restarted on ibrutinib and must not have had prior intolerance to ibrutinib that would prevent this; patients managed with prior dose reductions for toxicity will continue at the reduced dose for the remainder of this study
  • Indolent NHL or mantle cell NHL who are beyond first remission and previously treated with chemoimmunotherapy or who were not eligible for such therapy; patients who have relapsed following autologous or allogeneic HCT are eligible
  • Aggressive NHL such as diffuse large B-cell lymphoma (DLBCL), who have relapsed or have residual disease following treatment with curative intent; patients should have relapsed following, or not be eligible for high-dose therapy and autologous HCT; patients with chemotherapy refractory disease or marrow involvement or comorbidities precluding successful autologous HCT are eligible; patients may be treated following allogeneic HCT
  • Patients with CD19 expressing, relapsed or refractory ALL
  • Patients with one of the above diagnoses whose disease state does not qualify but who have prognostic indicators that suggest a high risk of progression of disease may be screened and undergo leukapheresis; enrollment for T cell therapy would require meeting the full disease state eligibility
