Infection and Tumour Antigen Cellular Therapy (INTACT-WT1)
Leukemia, Myelocytic, Acute
About this trial
This is an interventional prevention trial for Leukemia, Myelocytic, Acute
Eligibility Criteria
Inclusion Criteria:
- Patients undergoing myeloablative or non-myeloablative allogeneic transplantation from an HLA (A, B and DR) identical or 1-3 antigen mismatched family or unrelated donor
- Transplant performed for acute myeloid leukaemia
- Leukaemia blasts express the WT1 tumour antigen as determined by the European LeukaemiaNet standardised assay described in 16. WT1 overexpression will be defined by greater than 250 copies/104ABL copies in bone marrow samples or greater than 50 copies/104ABL copies in peripheral blood. This assay will be performed on samples collected as part of routine clinical care at diagnosis and during initial treatment prior to transplantation. Testing will be performed after consent for trial participation has been obtained and negativity for WT1 will be classified as screening failure
- Recipients of peripheral blood HSCT
- Adequate hepatic and renal function (< 3 x upper limit of normal for AST, ALT, < 2 x upper limit of normal for total bilirubin, serum creatinine)
- Estimated life expectancy of at least 12 months
- Patient (or legal representative) has given informed consent
Exclusion Criteria:
- Use of anti-lymphocyte globulin (ALG, ATG, Campath or other broad spectrum lymphocyte antibody) given in the 4 weeks immediately prior to infusion or planned within 4 weeks after infusion
- Grade II or greater graft versus host disease within 1 week prior to infusion
- Prednisone or methylprednisone at a dose of > 1 mg/kg (or equivalent in other steroid preparations) administered within 72 hours prior to cell infusion
- Prior allogeneic HSCT
- Privately insured in or outpatients (see Indemnity Issues, Section 11.4)

Arms of the Study
Arm 1
Experimental
Transplant Recipient
The T cell product administration is personalized cellular therapy product, individually prepared for each participant. Donor-derived WT1-CTL and P-CTL. It's exact make up and effect is dependent on both donor and recipient characteristics and as such variability is expected in the response. These variations will be adjusted for by multiple samplings over time and collation and analysis of response in both individuals an the group as a whole. One infusion of 2 x 107/m2 P-CTLs prophylactically on or after day 28 post-allogeneic peripheral blood haemopoietic stem cell transplant (HSCT), combined with up to four infusions of 2x107/m2 WT1-CTLs.
