Patients are treated with donor natural killer cells, fludarabine, cyclophosphamide, Denileukin diftitox, Donor lymphapheresis and IL-2.

Given by infusion on Day 0. The product is T cell-depleted (CD3-) and B cell-depleted (CD19). Target dose for infusion is \< or = 8 x 10\^7 nucleated cells/kilogram.

Natural Killer Cells

Administered as a 1 hour intravenous infusion once a day for 5 doses beginning on day -6.

Administered as a 2 hour intravenous infusion with high volume fluid flush and mesna per institutional guidelines on day -5 and -4 one hour after fludarabine infusion. (Day -4 administration may be omitted if patient has had a transplant in the previous 4 months.)

12 ug/kg/day will be administered on day -1 and day -2 intravenously.

Day -1 before planned NK cell infusion, the donor will undergo lymphapheresis (Removal of lymphocytes from donated blood, with the remainder of the blood retransfused into the donor).

Donor lymphapheresis

Administered after NK cell infusion, 10 million units every other day for a total of 6 doses. (Patients weighing less than 45 kilograms will receive a dose of 5 million units/m\^2 every other day for 6 doses).

IL-2

Jeffrey S. Miller, M.D.

This is a phase II therapeutic study of related donor HLA-haploidentical NK-cell based therapy after a high dose of fludarabine/cyclophosphamide with denileukin diftitox preparative regimen for the treatment of poor prognosis acute myelogenous leukemia (AML).

Patients achieving a complete remission and neutrophil recovery (ANC \> 500) for at least 4 weeks will be considered for allogeneic transplant to prolong remission (independent of this study).

All patients, including those who go on to transplant, will be followed to determine disease free survival, treatment related mortality, and time to relapse.

Haploidentical Natural Killer Cells to Treat Refractory or Relapsed Acute Myelogenous Leukemia (AML)

Adoptive Transfer of Haploidentical Natural Killer Cells to Treat Refractory or Relapsed AML MT2010-02

The primary objective of this study was to estimate the incidence of in vivo expansion of natural killer (NK) cells 14 days after infusion of an allogeneic donor product enriched for NK progenitors. Successful in vivo donor NK cell expansion was defined by measuring an absolute circulating donor-derived NK cell count of \>100 cells/ul in the patient's peripheral blood 14 days after infusion.

Disease response was defined as complete remission (disease response) by morphologic criteria including \<5% blasts in a moderately cellular or cellular marrow. Complete remission was also correlated with NK cell expansion in vivo, IL-15 levels and donor/recipient KIR B genotyping, and Treg depletion.

Number of patients alive and disease free at 6 months. The length of time after treatment ends that a patient survives without any signs or symptoms of that cancer or any other type of cancer. In a clinical trial, measuring the disease-free survival is one way to see how well a new treatment works.

Number of patients who have had a relapse(the return of disease after its apparent recovery/cessation) after obtaining a complete remission of their disease.

Number of patients who died within the first 100 days of treatment due to toxicity.

Association between in vivo natural killer (NK) cell expansion and complete response without platelet recovery (CRp) with donor killer immunoglobulin-like (KIR) genotype and Treg depletion. In vivo donor NK cell expansion was correlated with regulatory T-cell (Treg) depletion as detected on flow cytometry.

Due to chemotherapy as prep for the NK cell infusion, it is expected that all patients will experience severe depression of their blood counts and other related toxicities. Adverse event (AE) collection will focus on targeted AEs and unexpected AEs at specific time points in relation to the NK cell infusion and IL-2 injections.

Patients with acute myeloid leukemia (AML) are treated with donor natural killer cells, fludarabine, cyclophosphamide, Denileukin diftitox, Donor lymphapheresis and IL-2.
