This phase I/II trial studies the side effects and best dose of modified immune cells called CD19-CD22 chimeric antigen receptor (CAR) T cells in treating patients with CD19 positive(+), CD22+ B-acute lymphoblastic leukemia, chronic lymphocytic leukemia, or non-Hodgkin's lymphoma that has come back (recurrent) or does not respond to treatment (refractory). T-cells are collected from the patient and genetic materials called "chimeric antigen receptors (CAR)" are transferred to the collected T-cells. The CAR T-cells are then infused back to the patient's body. Giving CD19- CD22 CAR T cells after chemotherapy may help to control the disease.

PRIMARY OBJECTIVES:

I. To determine the safety of infusion with chimeric antigen receptor T cells targeting CD19 and CD22.

II. To find the recommended phase II dose for recurrent/refractory CD19+CD22+ B cell malignancies.

SECONDARY OBJECTIVES:

I. To describe the overall response rate and complete response rate of relapsed B cell malignancies treated with CAR-T cells targeting CD19 and CD22.

II. To assess other response variables including minimal residual disease (MRD) negative remission, overall survival (OS), and event free survival (EFS).

EXPLORATORY OBJECTIVES:

I. To evaluate the immune reconstitution and persistence of CAR T cells for one year post infusion.

OUTLINE: This is a phase I, dose escalation study of autologous CD19/CD22 chimeric antigen receptor T-cells (CD19-CD22 CAR T cells) followed by a phase II study.

Patients receive standard of care cyclophosphamide intravenously (IV) over 30 minutes and fludarabine IV over 30 minutes on days -5, -4, and -3, and then receive CD19-CD22 CAR T cells IV on day 0. Patients with relapsed or persistent disease after a protocol assessment may receive a second infusion of CD19-CD22 CAR T cells.

After completion of study treatment, patients are followed up at 1, 2, 3, 6, and 12 months.

Acceptable forms of birth control for male patients include condom with spermicide. If female participant becomes pregnant during the study, she will be taken off this study. If male participant fathers a child while on study, he must immediately notify his doctor
