Description
Inclusion Criteria:
Diagnosis of acute myeloid leukemia (AML) and meets one of the following disease criteria:
Primary induction failure:
- De novo AML - no CR after 2 or more chemotherapy induction attempts
- Secondary AML (from MDS or treatment related): no CR after 1 or more chemotherapy induction attempts
Relapse after chemotherapy: not in CR after 1, 2, or 3 re-induction attempts
- Patients > 60 years of age, the 1 cycle of chemotherapy is not required
Relapse after hematopoietic stem cell transplant:
- Relapse must have occurred > 18 months after transplant
- No re-induction required and no more than 1 re-induction attempt is allowed
Notes:
- For hypomethylating agents (i.e. decitabine, azacitidine) to count as an induction/re-induction attempt, the patient must have completed a minimum of 3 monthly cycles
- For targeting agents (i.e. sorafenib) to count as an induction/re-induction attempt, the patient must have completed a minimum of 1 month without attaining CR
- 7+3 followed by 5+2 counts as TWO induction attempts
- Use of hydroxyurea is permitted to control blasts until Day -3 per Section 8.7
- A history of AML related CNS involvement is allowed if CSF analysis is negative on 2 test dates at least 2 weeks apart prior to study treatment. The use of ongoing CNS maintenance therapy is allowed while on study.
- HLA-haploidentical related donor (aged 12 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 (at least 2/4 class I allele)
- Karnofsky Performance Status ≥ 60%
Adequate organ function within 14 days of study registration (28 days for pulmonary and cardiac) defined as:
- Creatinine: ≤ 2.0 mg/dL
- Hepatic: AST and ALT < 3 x upper limit of institutional normal
- Pulmonary Function: oxygen saturation ≥ 90% on room air; PFT's required only if symptomatic or prior known impairment - must have pulmonary function >50% corrected DLCO and FEV1.
- Cardiac Function: LVEF ≥ 40% by echocardiography, MUGA or cardiac MRI, no uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities.
- Able to be off prednisone or other systemic immunosuppressive medications for at least 3 days prior to NK cell infusion (excluding preparative regimen pre-medications) .
- Sexually active females of child bearing potential and males with partners of child bearing potential must agree to use effective contraception during therapy and for 4 months after completion of therapy .
- Voluntary written consent prior to the performance of any research related procedures.
Exclusion Criteria:
- Acute leukemias of ambiguous lineage
- Pregnant or breastfeeding - The agents used in this study include those that fall under Pregnancy Category D - have known teratogenic potential. Women of child bearing potential must have a negative pregnancy test at screening
- Active autoimmune disease requiring systemic immunosuppressive therapy
- History of severe asthma and currently on systemic chronic medications (mild asthma requiring inhaled steroids only is eligible)
- New or progressive pulmonary infiltrates on screening chest X-ray or chest CT scan unless cleared for study by Pulmonary. Infiltrates attributed to infection must be stable/improving (with associated clinical improvement) after 1 week of appropriate therapy (4 weeks for presumed or documented fungal infections).
- Uncontrolled bacterial, fungal or viral infections including HIV-1/2 or active hepatitis C/B - chronic asymptomatic viral hepatitis is allowed
- Received any investigational agent within the 14 days before the start of study treatment (1st dose of fludarabine)
- Prior ALT-803

---|---|
Experimental: Cy, FLU, Haplo NK and ALT-803
Preparative Regimen of Fludarabine and Cyclophosphamide ALT-803 Activation of Donor NK Cells ALT-803 to Facilitate NK Cell Survival and Expansion |
Preparative Regimen: Fludarabine 25 mg/m2 x 5 days start day -6 Cyclophosphamide 60 mg/kg x 2 days on day -5 and -4 ALT-803 Stimulated Donor NK Cells: The apheresis product (collected day -1) will be enriched for NK cells with the large-scale CliniMacs® device (Miltenyi) by depletion of CD3+ cells to remove T-lymphocytes and depletion of CD19+ cells to remove B-lymphocytes. The NK cell enriched product will be stimulated by overnight incubation with 36.1 ng/mL ALT-803 under GMP conditions and infused on day 0. ALT-803 to Facilitate NK Cell Survival and Expansion: ALT-803 at 10 mcg/kg subcutaneously (SC) with the 1st dose administered on day 0 (no sooner than 4 hours post NK cells), day +5 and day +10 for 3 doses total |
