This phase I trial studies the side effects and best dose of FATE-NK100 donor natural killer (NK) cells when given together with aldesleukin and combination chemotherapy in treating patients with acute myeloid leukemia that does not respond to treatment or has come back. The FATE-NK100 NK cell product is made from white blood cells collected from a related donor who is has been exposed to cytomegalovirus (CMV). These “adaptive” NK cells may have more potent anti-cancer killing. Aldesleukin may help FATE-NK100 cells expand and survive in the blood and bone marrow. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving FATE-NK100 donor natural killer cells together with aldesleukin and combination chemotherapy may work better treating patients with acute myeloid leukemia.

PRIMARY OBJECTIVES:
I. To assess the safety and determine the maximum tolerated dose (MTD) or maximum feasible dose (MFD) of allogeneic CD3- CD19- CD57+ NKG2C+ NK cells FATE-NK100 (FATE-NK100) administered intravenously (IV) in patients with refractory or relapsed acute myeloid leukemia (AML).
SECONDARY OBJECTIVES:
I. To assess clinical activity by complete remission/complete remission with incomplete platelet recovery (CR/CRp) at 42 days where CR is defined as =< 5% blasts in the bone marrow (BM), recovery of neutrophils and platelets, and the absence of extramedullary disease and CRp is defined as leukemia clearance (=< 5% marrow blasts and no circulating peripheral blasts) and neutrophil recovery but with incomplete platelet recovery.
II. To determine the incidence of in vivo expansion (>= 100 donor derived NK cells per uL blood) of NK cells by day +7 and day +14.
III. To evaluate the safety of FATE-NK100 as measured by rate of treatment related mortality (TRM) at 6 months.
IV. To evaluate the rate of minimal residual disease (MRD) clearance.
V. To measure leukemia free survival (LFS) and overall survival (OS) at 1 year.
CORRELATIVE OBJECTIVES:
I. To measure function of in vivo expanded adoptively transferred FATE-NK100.
II. To correlate CR/CRp with in vivo expansion of FATE-NK100.
OUTLINE: This is a dose-escalation study of FATE-NK100.
Patients receive fludarabine phosphate intravenously (IV) over 1 hour on days -6 to -2 and cyclophosphamide IV over 2 hours on days -5 and -4. Patients then receive FATE-NK100 IV over 15 minutes to 1 hour on day 0 and aldesleukin subcutaneously (SC) every other day (QOD) on days 0-10.
After completion of study treatment, patients are followed up at 2, 3, 6, and 12 months.
