| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To compare the efficacy of haploidentical NK-cell based consolidation with standard cytarabine based consolidation in elderly patients suffering from AML with high risk of fatal relapse and no option for allogeneic stem cell transplantation (SCT). |  | 
| E.2.2 | Secondary objectives of the trial | 
| - To compare the time to relapse (TTR), the cumulative incidence of relapse (CIR) and relapse-free survival (RFS) between the two study groups - To investigate the yield and purity of NK cells (CD3-CD56+) after CD3 de-pletion and CD56 enrichment
 - To investigate patients NC cell recovery, NK cell chimerism, NK phenotype and functional capacity of NK cells at various time points after infusion
 - To compare tolerability and safety of the two  interventions

| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| • Newly diagnosed AML other than acute promyelocytic leukemia (APL) according to WHO criteria, i.e. bone marrow aspirate or biopsy must have contained ≥20% blasts • Clinical performance corresponding to ECOG score 0-2
 • High-risk karyotype
 • <5% myeloblasts in bone marrow ≥21 days after beginning of most recent chemotherapy
 • maximal two preceding chemotherapy cycles (either two induction cycles or one induction + one consolidation cycle)
 • Study inclusion (experimental or control intervention) latest 56 days after preceding chemotherapy
 • Reconstitution of peripheral blood leukocytes following chemotherapy (total leukocytes >1.5 GPT/l; neutrophil granulocytes >0.5 GPT/l)
 • No available HLA-matched (≥ 9 of 10 HLA-alleles) stem cell donor or unfit for allogeneic hematopoietic stem cell transplantation
 • Available haploidentical family donor, willing and fit for NK cell donation
 |  | 
| E.4 | Principal exclusion criteria | 
| • AML with favorable risk cytogenetic features, i.e. t(15;17) or PML-RAR alpha transcript or t(8;21) or RUNX1 transcript or inv(16) or CBFa transcript • AML with t(9;11)(p22;q23)
 • AML with intermediate risk cytogenetic features, i.e. no high-risk cytogenetic features as defined in inclusion criteria and no favorable cyto-genetic features as defined in exclusion criteria, FLT3-ITD ratio ≤0.8
 • Persistent aplasia following preceding chemotherapy
 • Relapsed or refractory AML
 • Available HLA-matched (≥9 of 10 HLA-alleles) stem cell donor and patient fit for allogeneic stem cell transplantation
 • Age <60 years
 • Known pre-existing autoimmune diseases
 • Any severe concomitant condition which makes it undesirable for the patient to participate in the study (e.g. end stage irreversible multi organ failure, HIV infection, uncontrolled active infections >°2 )
 • Any condition which could jeorpadize compliance of the protocol
 • Participation in another clinical trial (investigational drug therapy outside of this trial) during or within 4 weeks before study entry
