Brief Summary:
This is a Phase I open-label dose escalation study of a single infusion of FATE-NK100 and a short course of subcutaneous interleukin-2 (IL-2) administered after lymphodepleting chemotherapy (CY/FLU) in subjects with refractory or relapsed acute myelogenous leukemia (AML). FATE-NK100 is a natural killer (NK) cell product that is enriched for NK cells with an "adaptive", or human cytomegalovirus (CMV)-induced, phenotype. The NK cell product is comprised of peripheral blood (PB) leukocytes sourced from a related donor (HLA-haploidentical or better but not fully HLA-matched) that is seropositive for cytomegalovirus (CMV+), and enriched for adaptive NK cells by depletion of CD3+ (T-lymphocytes) and CD19+ (B-lymphocytes) cells followed by ex-vivo culture expansion.

  3. In vivo expansion of NK cells [ Time Frame: Day +14 ]
    Incidence of in vivo expansion (≥ 100 donor derived NK cells per uL blood) of NK cells

  4. Treatment Related Mortality (TRM) [ Time Frame: 6 months ]

  6. Minimal residual disease (MRD) by flow cytometry [ Time Frame: up to Day 28 ]
    Incidence of minimal residual disease (MRD) clearance by flow cytometry after NK Cell infusion

  7. Leukemia free survival (LFS) [ Time Frame: 1 year ]
    Incidence of Leukemia free survival (LFS)

  8. Overall survival (OS) [ Time Frame: 1 year ]
    Incidence of overall survival (OS)

Criteria

Inclusion Criteria:

- ≥18 but ≤ 70 years of age

  • Diagnosis of acute myeloid leukemia (AML) and meets one of the following disease criteria:

    * Primary induction failure:

    ** De Novo AML: no CR after 2, 3 or 4 induction attempts with high dose chemotherapy

    • Secondary AML (from MDS or treatment related): no CR after 1, 2 or 3 cycles of high dose chemotherapy

      • Relapsed:
    • Not in CR after 1 or 2 cycles of standard re-induction therapy
    • Relapse diagnosed at the time of the 6 months post-HCT standard of care follow-up or later (i.e. based on bone marrow biopsy performed Day +170 or later) and without evidence of graft versus host disease (GVHD)

      • For patients > 60 years of age, the minimum of 1 cycle of standard chemotherapy is not required.
  • Available HLA-matched or better but not fully HLA-matched (2/4 or 3/4 antigens) related donor (aged 18 to 75 years) with donor/recipient match based on a minimum of intermediate resolution DNA based Class I typing of the A and B locus who is CMV seropositive.
  • Karnofsky Performance Status ≥ 60%
