To assess the response rate to DLI by the combination with azacytidine in the population of patients with relapsed AML and MDS after allo-SCT. |
|
E.2.2 | Secondary objectives of the trial |
- To evaluate disease-free survival at 2 years.
- To evaluate overall survival at 2 years.
- To assess the toxicity profile (hematological and non-hematological).
- To assess the incidence and severity of GvHD.
- To assess the incidence and severity of infections.
- To compare the study cohort to an historical group of patients with similar characteristics. |

E.3 | Principal inclusion criteria |
Patients :
-Age ≥ 18 years.
-Be able to understand and sign informed consent.
-Fertile patients must use a reliable contraception method.
Disease status at transplantation :
-Acute myelogenous leukemia (AML) in first or subsequent complete remission (< 5% marrow blasts).
-Myelodysplastic syndrome (MDS) with less than 10% marrow blasts at the time of transplantation.
Transplantation :
-Allogeneic transplantation using a sibling or unrelated donor with matching in 10/10 alleles (HLA-A, B, C, DRB1, DQB1) or maximum of one allele or one antigen or 1 antigen + 1 allele or 1 antigen + 1 DQB1 antigen or 2 alleles mismatches.
-Standard or reduced-intensity conditioning.
-Second transplantation is allowed.
-Donor is willing to donate lymphocytes.
Clinical situation:
-Cytologic relapse after allo-stem cell transplantation defined as the recurrence of more than 5% blasts on bone marrow aspiration (AML) or evidence of MDS
-Immunophenotypic relapse defined as the recurrence of an abnormal phenotype on flow cytometry in bone marrow aspirate.
-Cytogenetic or molecular relapse defined as the persistence or recurrence of a cytogenetic abnormality or molecular marker in bone marrow aspiration or peripheral blood. WT1 expression is not considered as reliable marker for relapse in this protocol but FLT3-ITD, NPM1, CEBPA, or translocation-specific markers (such as MLL-PTD, AML-ETO, CBFB-MYH11) are.
Immunosuppressive therapy should have been stopped before inclusion.
|
|
E.4 | Principal exclusion criteria |
-More than 30% marrow blasts at the time of inclusion.
-Extramedullary relapse including central nervous involvement.
-ECOG Performance status > 2.
-Active acute grade II-IV GvHD at the time of inclusion.
-Active chronic GvHD requiring systemic therapy at the time of inclusion.
-Uncontrolled infection.
-HIV positive.
-Acute or chronic heart failure (NYHA class III or IV) or symptomatic ischemic heart disease or
ejection fraction < 35% or uncontrolled arrhythmia.
-Severe liver failure (total bilirubin > 3 mg/dL, SGPT > 4 X upper normal limit).
-Severe pulmonary failure (corrected DLCo < 35%).
-Terminal renal failure requiring dialysis.
-Severe neurological or psychiatric disorders.
-Concurrent investigational drug.
-Other treatment for relapse, except for hydroxyurea but it should be stopped before inclusion in the study.
-Female who is pregnant or breastfeeding.
