Outcome Measures

Primary Outcomes (2)

  • Incidence of dose limiting toxicity (DLT) following CD19+CD22 CAR T-cell infusion

    The incidence of dose limiting toxicity (DLT) occurring within 28 days of CD19+CD22CAR T-cell infusion.

    28 days

  • Molecular remission

    Efficacy will be assessed by determining Minimal Residual Disease in the bone marrow aspirate using immunoglobulin heavy chain (IgH) quantitative polymerase chain reaction (qPCR) and/or Next Generation Sequencing in all patients. The proportion of patients achieving molecular remission at 28 days post CD19+CD22CAR T-cell infusion will be determined.

    28 days

Secondary Outcomes (10)

  • Feasibility of Generation of CD19+CD22 CAR T-cells

    Day 28

  • Molecular Remission

    3 months

  • Long-Term Molecular Remission

    2 years

  • Duration of Response

    15 years

  • Safety and Tolerability of the CAR T-cells

    15 years

  • +5 more secondary outcomes

Study Arms (1)

CD19+CD22 CAR T-cells

EXPERIMENTAL

Patients meeting the eligibility criteria will have leukapheresis to isolate the blood immune cells used to manufacture the CD19+CD22CAR T-cells. Patients will receive lymphodepletion with low dose total body irradiation, fludarabine and cyclophosphamide prior to infusion of the CD19+CD22CAR T-cells.

Procedure: LeukapheresisRadiation: Total Body Irradiation (TBI)Drug: Lymphodepletion with FludarabineDrug: Lymphodepletion with CyclophosphamideBiological: CD19+CD22 CAR T-cells

Interventions

LeukapheresisPROCEDURE

Patients will undergo an unstimulated leukapheresis to isolate the required immune cells to produce the CD19+CD22 CAR T-cells

CD19+CD22 CAR T-cells

Participants will receive total body irradiation delivered as a single fraction (2Gy) on day -7 prior to CD19+CD22CAR T-cell infusion.

CD19+CD22 CAR T-cells

Patients will receive lymphodepleting chemotherapy with iv fludarabine 30 mg/m2 on days -6 to -3 prior to CD19+CD22CAR T-cell infusion.

CD19+CD22 CAR T-cells

Patients will receive lymphodepleting chemotherapy with iv cyclophosphamide 0.5 g/m2 on days -6 to -5 prior to CD19+CD22CAR T-cell infusion.

CD19+CD22 CAR T-cells

Dose level 1: 2 doses of 4 x 10\^5 CD19+CD22 CAR T-cells/kg Dose level 2: 2 doses of 1 x 10\^6 CD19+CD22 CAR T-cells/kg given as a split dose as an intravenous injection through a Hickman line or PICC line (peripherally inserted central catheter) on day 0 and day 14.
