Phase I/II Study of Immune Therapy After Allograft in Patients With Myeloid Hemopathy (ALLO-WT1)
Etude Phase I/II d'immunothérapie Par protéine recWT1-A10+AS01B après Greffe allogénique de Cellules Souches
Patients with acute or chronic myeloid leukemia, or myelodysplastic syndrome, underwent allogeneic stem cell transplantation from HLA-identical donor (related or unrelated) after reduced-intensity conditioning regimen.
If WT1 expression is detectable on tumor cells, they will receive an immune therapy 60 days after allograft.
6 administrations every 2 weeks of the protein recwt1-A10+AS01B will be administrated.
The safety and immunological efficacy of this immune therapy after hematopoietic stem cells transplantation with reduced intensity conditioning will be evaluated.

Description
Inclusion Criteria:
- Patients older than 18 and younger than 65 years.
- Karnofsky ≥ 70 %.
- Patients with acute or chronic myeloid leukemia, or myelodysplastic syndrome, who underwent allogeneic stem cell transplantation from HLA-identical donor (related or unrelated) after reduced-intensity conditioning regimen.
- Patients in morphologic complete remission at the time of transplantation.
- WT1 expression detectable on tumor cells.
- Expected life duration more than 6 months.
- Creatinine clearance ≥ 50 ml/min
- Bilirubinemia < 1.5N and ASAT < 2.5N.
- Women of childbearing age: negative pregnancy test and effective contraception for at least 30 days before vaccinal immunotherapy (the same contraceptive method must be continued at least 2 months after the last vaccine infusion).
- Membership of a social security scheme or beneficiary of such a regime.
- Signed inform consent.
Exclusion Criteria:
- Patients with severe and uncontrolled affections, especially active graft-versus-host disease requiring steroid treatment (>0.3 mg/kg/j) and/or Mycophenolate mofetil.
- Pregnant or lactating women.
- HIV seropositive patients.
- Autoimmune disease (Lupus, multiple sclerosis, Chron disease…)
- Previous history of allergic state which could be potentially compound by a component of the vaccinal immunotherapy.
- Patients who received (or are planned to receive) another experimental treatment within 30 days following the first infusion of the experimental drug of this protocol.
- Previous history of another cancer, except if considered as probably cured by the investigator.
- Patients deprived of liberty, or under guardianship.
