Summary

AML patients with de-novo or secondary disease with age greater than 18 years not eligible for stem cell transplantation for medical contraindications, lack of donor or lack of stem cells,are eligible. Leukemias other than AML and M3 FAB subtype will be excluded from the study. Immunosuppressive chemotherapy prior to NK cell infusion will include: fludarabine and cyclophosphamide 4g/m2 (Flu/Cy). The therapy will be administered over 6 days on inpatient basis. Haploidentical NK cells will be selected from a steady-state large volume leukapheresis product from a suitable KIR ligand incompatible donor. Donor-recipients pairs will be selected on the basis of known KIR ligands. In particular, haploidentical donors will be included if present at least one allele mismatch at a class I locus among the following ones: HLA-C alleles with Asn77-Lys80, HLA-C alleles with Ser77-Asn80, HLA-Bw4 alleles. Immunomagnetic enrichment of NK cells will follow two subsequent steps: 1) depletion of CD3+ T cells followed by 2) positive selection of CD56+ NK cells. Contaminating CD3+ T cells will be carefully evaluated.
