Eligibility
Inclusion criteria
Inclusion criteria: Subjects must meet all of the following inclusion criteria to be eligible for enrolment into the trial: Diagnosis and main criteria for admission to screening phase of trial: The trial will recruit subjects with MDS or AML who have received hypomethylating agent therapy (at least 6 cycles of azacitidine or 4 cycles of decitabine), and are EITHER: • Relapsed, defined as failing to maintain an initial IWG response OR • Stable, defined as failing to achieve an IWG response IWG response is defined as complete remission; partial remission; marrow complete remission; cytogenetic response; stable disease with haematological improvement. Subjects who have received hypomethylating agent therapy as part of a combination regimen may be eligible after discussion with the Sponsor. 1. Subjects aged 18 years or older who have a diagnosis of, EITHER: • MDS with an IPSS of intermediate -2, or high and one of the following FAB types: o Refractory anaemia with excess blasts (RAEB) o Chronic myelomonocytic leukaemia (CMML) with at least 10% bone marrow blasts (WHO CMML II) OR • AML (diagnosed according to WHO classification 2008 revision) 2. Subjects with documented HLA-A*0201 positive serotype 3. Subjects with less than 30 per cent bone marrow blasts 4. Subjects with relapsed disease must have less than 5 per cent peripheral blasts 5. Subjects with stable disease must have less than 10 per cent peripheral blasts 6. Subjects with less than a doubling of bone marrow blast count between the start of hypomethylating agent therapy and the date of screening 7. Subjects to complete screen 1 visit within a minimum of 28 days and maximum of 90 days since completion of azacitidine or decitabine therapy. Subjects who have exceeded the 90 day window may be eligible after discussion with the Sponsor. 8. Subjects with ECOG status 0, 1 or 2 9. Subjects who have at least one cytopenia (ANC =65 years) yes F.1.3.1 Number of subjects for this age range 30

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To examine the safety and proportion of subjects achieving one or more IWG (2006) response criteria (within 12 months) following gene-modified WT1 TCR therapy ;Secondary Objective: • To examine the safety and tolerability of gene-modified WT1 TCR therapy • To evaluate the clinical efficacy of gene-modified WT1 TCR therapy • To confirm the technical feasibility of gene-modified WT1 TCR therapy in subjects with myelodysplastic syndrome (MDS) or acute myeloid leukaemia (AML) with low blast count • To determine the persistence and function of WT1 TCR-transduced T cells;Primary end point(s): Efficacy Proportion of subjects achieving one or more of the following IWG response criteria within 12 months of administration of gene-modified WT1 TCR T cell therapy: complete remission; partial remission; marrow complete remission; cytogenetic response; haematological improvement Safety Suspected Unexpected Serious Adverse reactions ;Timepoint(s) of evaluation of this end point: Efficacy Within 12 months of administration of gene-modified WT1 TCR T cell therapy Safety 12 months after each patient recieves last dose | — |
