Coadministration of Malignancy and Infection specific T cells after allogeneic stem cell Transplant for Acute Leukaemia with CD34+ selected stem cells


Sponsor

Enrollment

20 participants

Start Date

Oct 12, 2018

Study Type

Conditions

Summary

The study will analyse the safety and biological efficacy of administering the investigational products (donor-derived T cells stimulated with WT1 or engineered to express a CD19 chimeric antigen receptor, together with donor derived T cells stimulated with viral and fungal antigens) for the prevention of relapse and viral/fungal illnesses in patients undergoing transplantation for acute leukaemia in first complete remission. Who is it for? You may be eligible for this study if you are 69 years or younger and are undergoing an allogeneic transplant for the treatment of either acute myeloid leukaemia or acute lymphoblastic leukaemia. Study details Participants will receive a bone marrow transplant. 21 days following the transplant, participants may receive an infusion of T cells made from their donor’s cells that is anticipated will help fight off infections. Following this, participants may be eligible to receive up to 4 Tcell infusions that is anticipated to help fight cancer. Patients will then be followed up for 12 months (for AML patients) or 15 years (for ALL patients). Over this time you will be asked to donate extra blood for clinical trial use which will mostly be collected at blood tests that are required for normal transplant follow up. It is hoped that this research will provide safer and more effective blood or marrow transplants for those suffering from leukaemia.

Plain Language Summary

Simplified for easier understanding

Leukaemia is a cancer of the blood and bone marrow. For some patients with acute leukaemia (AML or ALL) in remission, a bone marrow transplant from a donor (allogeneic transplant) offers the best chance of long-term cure — but relapse and serious infections after the transplant remain major risks. This study is testing a specialised approach where, after the transplant, patients receive infusions of donor immune cells specifically trained to recognise and attack either the leukaemia or dangerous viruses and fungi. Participants will receive their transplant first, then approximately 21 days later may receive an infusion of virus- and fungus-fighting T cells, followed by up to four infusions of cancer-fighting T cells targeting the specific markers on their leukaemia. Patients will then be followed for up to 15 years. You may be eligible if you are aged 1 to 69 and are undergoing a first myeloablative or non-myeloablative allogeneic bone marrow transplant for AML or ALL in first complete remission. A matched family or unrelated donor must be available, and your leukaemia cells must express the required target markers.

Interventions

The study treatment will consist of an infusion of CD34 selected donor stem cells on day 0 of the fully-matched related allogeneic bone marrow transplant. A minimum of 21 days following the transplant

The study treatment will consist of an infusion of CD34 selected donor stem cells on day 0 of the fully-matched related allogeneic bone marrow transplant. A minimum of 21 days following the transplant, one intravenous infusion of 2 x 107/m2 of pathogen specific T cells will be given over 1 minute to all patients following myeloid engraftment. In addition, up to a total of four intravenous infusions of 2x107/m2 either WT1 specific T cells for patients with AML or CAR19 T cells for patients with ALL will be given to the patient no less than 28 days apart unless contraindicated. Such contraindications are fever, hypotension, tachycardia, hypoxemia, graft versus host disease greater than or equal to grade II in the week prior to infusion, abnormal liver function >3x upper limit normal. The pathogen specific and malignancy specific cells can be given and monitored as an outpatient (eg: the Cancer Day Suite) by study investigators or other staff as delegated by the investigator's (eg: BMT Fellow, Clinical Nurse Specialists, Nurse Practitioners). The patients will be followed up at 3 months post transplant and 6 months post transplant. ALL patients will be followed up at additional time points of 12months and yearly for 15 years for the detection of long term adverse event outcomes. The bone marrow transplant will occur and delivered as an inpatient as per standard of care.
