Brief Summary:
This study aims to evaluate the safety, efficacy and duration of response of CD19/22 Chimeric Antigen Receptor (CAR) redirected autologous T-cells in children with high risk, relapsed CD19+ and/ or CD22+ haematological malignancies.

Condition or disease Intervention/treatment Phase
Acute Lymphoblastic Leukemia Burkitt Lymphoma Procedure: Leukapheresis Drug: Lymphodepletion with fludarabine Drug: Lymphodepletion with cyclophosphamide Biological: CD19/22 CAR T-cells Phase 1

Detailed Description:
This is a multi-centre, non-randomised, open label Phase I clinical trial of an Advanced Therapy Investigational Medicinal Product named CD19/22 Chimeric Antigen Receptor (CAR) T-cells (CD19/22 CAR T-cells) in children and young adults (age <24 years) with high risk, relapsed CD19+ and/or CD1922+ haematological malignancies (Acute Lymphoblastic Leukemia and Burkitt's lymphoma). Following informed consent and registration to the trial, patients will undergo an unstimulated leukapheresis for the generation of the CD19/22 CAR T-cells. Patients will receive the CD19/22CAR T-cells following lymphodepleting chemotherapy. The study will evaluate the safety, efficacy and duration of response of the CD19/22 CAR T-cells in children with high risk relapsed CD19+ and or CD22+ malignancies.

Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Immunotherapy With CD19/22 CAR Redirected T-cells for High Risk, Relapsed Paediatric CD19+ and/or CD22+ Acute Lymphoblastic Leukaemia and Other Haematological Malignancies
Actual Study Start Date : April 2016
Estimated Primary Completion Date : December 31, 2028
Estimated Study Completion Date : December 31, 2036


Arm Intervention/treatment
Experimental: CD19/22 CAR T-cells
Patients meeting the eligibility criteria will have leukapheresis to isolate the blood immune cells used to manufacture the CD19/22CAR T-cells. Patients will receive lymphodepletion with fludarabine and cyclophosphamide prior to infusion of the CD19/22CAR T-cells.
Procedure: Leukapheresis
Patients will undergo an unstimulated leukapheresis to isolate the required immune cells to produce the CD19/22 CAR T-cells

Drug: Lymphodepletion with fludarabine
Patients will receive lymphodepleting chemotherapy with iv fludarabine 30 mg/m2 on days -7 to -3 prior to CD19/22CAR T-cell infusion.

Drug: Lymphodepletion with cyclophosphamide
Patients will receive lymphodepleting chemotherapy with iv cyclophosphamide 0.5 g/m2 on days -4 to -2 prior to CD19/22CAR T-cell infusion.

Biological: CD19/22 CAR T-cells
A single dose of 1 x 10^6/kg CD19/22CAR transduced T-cells will be given as an intravenous injection through a Hickman line or PICC line(peripherally inserted central catheter) on day 0.




Primary Outcome Measures :
  1. Toxicity evaluation following CD19/22CAR T-cell infusion [ Time Frame: 1 month ]
    The incidence of grade 3-5 toxicity occurring within 60 days of CD19/22CAR T-cell infusion. In particular, the incidence of Severe Cytokine Release Syndrome and Grade 3-5 neurotoxicity occurring within 30 days of CD19/22CAR T-cell infusion.

  2. Molecular remission [ Time Frame: 1 month ]
    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 1 month post CD19/22CAR T-cell infusion will be determined.


Secondary Outcome Measures :
  1. Long term molecular remission [ Time Frame: 2 years ]
    Number of patients in molecular remission without further therapy at 2 years

  2. Frequency of circulating CD19/22 CAR T-cells [ Time Frame: 2 years ]
    Persistence and frequency of circulating CD19/22CAR T-cells in the peripheral blood by flow cytometry and qPCR analyses.

  3. Incidence of hypogammaglobulinaemia [ Time Frame: 2 years ]
    Incidence and duration of hypogammaglobulinaemia

  4. Relapse rate [ Time Frame: 10 years ]
    Relapse rate monitored during interventional phase and long term follow up for a total of10 years post cell infusion. Number of patients who relapsed can be summarized as a percentage or rate(for all patients registered to the trial, and also only for those who received the cell infusion).

  5. Overall Survival [ Time Frame: 10 years ]
    Overall survival is monitored during interventional phase and long term follow up for 10 years post-CD19/22 CAR T-cell infusion. Number of patients alive can be summarized as a percentage (for all patients registered to the trial, and also only for those who received the cell infusion).
