Cytokine induced memory-like natural killer (CIML NK) cells combined with IL-2 in adult patients (18 years of age or older) with Acute Myeloid Leukemia (AML), Myelodysplastic Syndrome (MDS) and Myeloproliferative Neoplasms (MPN) who relapse after haploidentical hematopoietic cell transplantation (haplo-HCT) or HLA matched stem cells. This evidence concerns the gene IL2 and myeloproliferative disorder.
