RecruitingPhase 1Biological interventionPreemptive CIML NK Cell Therapy After Hematopoietic Stem Cell TransplantationThe purpose of this research study is to test the safety and efficacy of cytokine induced memory-like (CIML) natural killer (NK) cells expanded with Interleukin-2 (IL-2) at preventing relapse in acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), or MDS and myeloproliferative neoplasm (MPN) overlap syndrome after a standard-of-care stem cell transplant. Names of the study therapies involved in this study are: * CIML NK cells intravenous infusion (cellular therapy) * Subcutaneous Interleukin-2 (recombinant, human glycoprotein)
