Haploidentical Stem Cell Transplant With or Without NK Cell Infusion in AML and MDS (Bigeminy)
Haploidentical Stem Cell Transplantation With or Without NK Cell Infusion in Refractory/Relapsed Acute Myeloid Leukemia and Myelodysplastic Syndrome:The BigEMINy Study
Relapse after an allogeneic hematopoietic stem cell transplantation (HSCT) is high in patients with advanced AML, in the 50% range. NK cells have been shown to possess significant anti-leukemic activity and may be used to reduce the incidence of relapse in patients with advanced AML.
Investigators hypothesize that the administration of a purified boost of NK cells on day +7 post HSCT, will reduce the incidence of relapse from the current 50% to 25%. In a phase III multicenter clinical study, 116 patients will be randomized to receive or not a boost of donor NK cells on day +7 post-HSCT. The first 10 patients in the experimental arm will be analyzed for toxicity. The stopping rule will be a transplant related mortality of more than 50% in the first 20 patients who received NK cells.

Experimental: Haplo-stem cell transplant followed by NK infusion
Haplo stem cell transplant (from bone marrow or apheresis) is followed by a haplo-NK cell infusion (target dose ≥1*106/kg b.w.) at day 7. Unstimulated haplo-NK cells are collected through apheresis Mononuclear cells are then subjected to a preliminary negative selection of CD3+ cells and to a subsequent positive selection of CD56+ cells. CD3 negative/CD56 positive cells are infused |
Patients in this arm receive haplo-SCT followed by one boost of NK cells one/two weeks after the transplant.
Lymphocyte are collected by apheresis from the donor one-two weeks after BM harvest.
CD3 negative/CD56 positive cells are selected by immunomagnetic columns (other lymphocytes are stored to be used as DLI)

Active Comparator: Haplo-stem cell transplant
Patients in this arm receive standard haplo stem cell transplant (from bone marrow or apheresis) transplant without subsequent NK cell infusion.
|
Patients in this arm receive a standard haplo-SCT.
All administerd therapies are the same as in other arm, except for the NK cell boost..
