Conditions

Summary

The aim of this project is to evaluate the Safety of Immune Cells for Patients with Relapsed Leukaemia or Lymphoma after Bone Marrow Transplant. Who is it for? You may be eligible to join this study if you have persistent or relapsed B-cell malignancy post related donor allogeneic stem cell transplant and a donor willing and available to donate peripheral blood for the generation of CAR19 T-cells. Study details Matched related donor derived CAR19 T-cells will be administered intravenously after lymphodepleting cyclophosphamide and fludarabine. This T-cell therapy may be administered alone or in addition to salvage chemotherapy. Three CAR19 T-cell dose levels will be assessed within each patient: 1x10^7cells/m^2, 5x10^7cells/m^2 and 1x10^8/m^2. Dose escalation will be determined 4 weeks after the last dose dependent on persistence of disease, no severe toxicity and falling CAR19 T-cell numbers. Patients will be monitored for early and long term toxicity, persistence of CAR T-cells and disease response. If successful, this treatment will enable the widespread application of CAR19 T-cells to patients with few other effective treatment options.

Plain Language Summary

Simplified for easier understanding

This study is for patients whose B-cell leukaemia or lymphoma has come back after a bone marrow transplant. It tests a type of immune cell therapy called CAR19 T-cells — specially engineered immune cells from the original bone marrow donor — to fight the returning cancer. The study primarily checks whether this therapy is safe. You may be eligible if: - You have B-cell blood cancer (leukaemia or lymphoma) that has returned or persisted after an allogeneic (donor) bone marrow transplant - You have a matched related donor who is willing and available to donate blood cells - Your overall health score (Karnofsky/Lansky) is at least 50% - Your life expectancy is at least 6 weeks You may NOT be eligible if: - You have an uncontrolled ongoing infection - You have significant graft-versus-host disease (grade II or above) - You are pregnant or breastfeeding - You have a history of seizures - You are currently on high-dose corticosteroids - You have had a recent (within 10 weeks) unmanipulated donor lymphocyte infusion Talk to your doctor about whether this trial might be right for you.

Up to 20 patients will receive allogeneic matched sibling donor derived CD19-specific chimeric antigen receptor (CAR19) T-cells for relapsed or persistent B-cell malignancy detected at any time post allogeneic stem cell transplant. Patients with active disease requiring therapy while CAR19 T-cells are being prepared will receive chemotherapy or radiotherapy as appropriate determined by the patient's usual treating physician. Matched related donor derived CAR19 T-cells will be administered intravenously after lymphodepleting cyclophosphamide 250mg/m^2 IV and fludarabine 25mg/m^2 IV daily on days -4 to -2 prior to CAR19 T-cell administration on day 0. Three CAR19 T-cell dose levels will be assessed within each patient: 1x10^7cells/m^2, 5x10^7cells/m^2 and 1x10^8/m^2. Patients will receive 1 dose only at each level. Dose escalation will be determined 4 weeks after the last dose dependent on persistence of disease, no severe toxicity and falling CAR19 T-cell numbers.
