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.

Eligibility Criteria

Inclusion Criteria

INCLUSIONS FOR SCREENING AND LEUKAPHERESIS

  • Patients with CD19 expressing acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL) or non-Hodgkin lymphoma (NHL)
  • Ability to understand and provide informed consent
  • Not human immunodeficiency virus (HIV) infected

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
  • Confirmation of diagnosis
  • Evidence of CD19 expression by immunohistochemistry or flow cytometry on any prior or current tumor specimen or high likelihood of CD19 expression based on disease histology
  • Karnofsky performance status >= 60%
  • All patients of childbearing potential must be willing to use a contraceptive method before, during, and for at least two months after the T cell infusion
  • Ability to understand and provide informed consent

Exclusion Criteria

EXCLUSIONS FOR CAR-T CELL THERAPY

  • Patients requiring ongoing daily corticosteroid therapy at a dose of > 15 mg of prednisone per day (or equivalent); pulsed corticosteroid use for disease control is acceptable
  • Active autoimmune disease requiring immunosuppressive therapy is excluded unless discussed with the Principal Investigator (PI)
  • Serum creatinine > 2.5 mg/dL
  • Serum glutamic oxaloacetic transaminase (SGOT) > 5 x upper limit of normal
  • Bilirubin > 3.0 mg/dL
  • Patients with clinically significant pulmonary dysfunction, as determined by medical history and physical exam should undergo pulmonary function testing; those with a forced expiratory volume in one second (FEV1) of < 50 % of predicted will be excluded
  • Diffusing capacity of the lung for carbon monoxide (DLCO) (corrected) < 40% will be excluded
  • Significant cardiovascular abnormalities as defined by any one of the following: New York Heart Association (NYHA) class III or IV congestive heart failure, clinically significant hypotension, uncontrolled symptomatic coronary artery disease, or a documented ejection fraction of < 35%
  • Uncontrolled active infection
