This is an interventional treatment trial for Acute Myeloid Leukemia focused on measuring Acute Myeloid Leukemia, High Risk Relapse, Complete Remission, Allogeneic Natural Killer Cells Read More

Inclusion Criteria:

1. The patient has pathologically documented AML and is in CR1 at the time of the screening visit
2. The patient achieved CR1 within 10 weeks of the screening visit; the patient may have received post-remission consolidation therapy (except for transplant) prior to the screening visit
3. A bone marrow aspiration performed within 21 days prior to the start of pre-infusion preparative therapy confirms the patient is in CR1

4. The patient has either refused or is not considered an appropriate immediate candidate for transplantation and is considered to be at high risk for recurrence by having at least one of the following prognostic factors:

   • High risk cytogenetics (-5, -7, del(5q), abnormal 3q, 11q23 translocations, complex cytogenetics) or if cytogenetics are normal the presence of a FLT3 mutation without a NPM1 mutation
   • Age > 60 years
   • Antecedent hematological disorder (AHD)
   • AML that is considered to be therapy-related
   • FAB subtype M0 (minimally differentiated acute myeloblastic leukemia), M6 (acute erythroid leukemias, including erythroleukemia (M6a) and pure erythroid leukemia (M6b)), or M7 (acute megakaryoblastic leukemia)
5. The patient is male or female, age 18 years or older
6. The patient has an ECOG performance status of 0, 1, or 2
7. The patient has an available NK cell donor who is a HLA haploidentical first-degree (parent, child, or sibling) or second-degree (child of a sibling) relative; minimum testing will be for HLA-A, HLA-B, and HLA-DR with donors matched for 3/6, 4/6 or 5/6 antigens
8. The patient has an absence of coexisting medical problems that would significantly increase the risk of the chemotherapy procedure (e.g. poor left ventricular ejection fraction [LVEF<40%])
9. The patient has recovered from reversible toxicity from prior therapy. Permanent and stable side effects or changes are acceptable if ≤ Grade 1 (CTCAE, v4.03)
10. The patient has serum creatinine <2×ULN and not rising for at least 2-4 weeks before chemotherapy. If elevated, the 24-hour creatinine clearance must be >50 mL/min
11. The patient has serum total bilirubin < 2 g/dL (unless the patient has a diagnosis of Gilbert's disease), SGOT (ALT) <3.5×ULN, and SGPT (AST) <3.5×ULN
12. The patient has an absolute neutrophil count (ANC) ≥1000/µL, platelets ≥100,000/µL and is not transfusion dependent for platelets and/or red cells
13. The patient has LVEF ≥40% by ECHO or MUGA scan and no clinically significant abnormalities in 12-lead ECG
14. The patient has a PT (or INR) and PTT up to 1.25×ULN
15. The patient must not be dependent on supplemental oxygen
16. The patient is using an effective contraceptive (per the institutional standard), if procreative potential exists
17. The patient must be willing and able to comply with all study protocol requirements. The patient or a legally authorized representative must fully understand all elements of the informed consent and have signed the informed consent according to institutional and federal regulatory requirements
18. The patient has not received an investigational chemotherapy within the last 28 days prior to the screening visit and has never received investigational immunotherapy. In addition, the patient must not receive treatment for AML (including treatment with IL-2 or IFNγ) in the interval of time between the screening visit and initiation of pre-infusion preparative therapy

Exclusion Criteria:

1. The patient had a previous bone marrow or stem cell transplant
2. The patient is seropositive for HIV 1, HIV 2, HBV, or HCV
3. The patient has a psychiatric, addictive, neurological or other disorder that compromises the ability to give informed consent or comply with study requirements
4. The patient is pregnant (confirmed by urine or serum pregnancy test) or lactating
5. The patient has a recently diagnosed active malignancy requiring therapy
6. The patient has an uncontrolled infection, or is receiving anti-fungal treatment for an ongoing infection
7. The patient has known hypersensitivity to bovine proteins
8. The patient has any condition that will place the patient at undue risk or discomfort as a result of adherence to study procedures
9. The patient requires treatment with corticosteroids at a dose > 0.1 mg/kg/day or has a known allergy to DSMO
