Brief Summary:
This is a multi-institutional Simon's optimal two-stage phase II trial of CD3/CD19 depleted, ALT-803 activated, haploidentical donor NK cells and subcutaneous ALT-803 given after lymphodepleting chemotherapy (CY/FLU) for the treatment of refractory or released acute myelogenous leukemia (AML).

Condition or disease Intervention/treatment Phase
Acute Myeloid Leukemia Biological: ALT-803 Phase 2

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 24 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: QUILT-3.033: Haploidentical Donor Natural Killer (NK) Cell Infusion With Subcutaneous ALT-803 in Adults With Refractory or Relapsed Acute Myelogenous Leukemia
Actual Study Start Date : May 16, 2017
Estimated Primary Completion Date : September 2020
Estimated Study Completion Date : September 2020


Arm Intervention/treatment
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

Biological: ALT-803

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





Primary Outcome Measures :
  1. Rate of complete remission with or without incomplete platelet recovery [ Time Frame: Day 42 post NK cell infusion ]
    To estimate the rate of complete remission with incomplete platelet recovery (CRp) - defined as leukemic clearance and neutrophil recovery without platelet recovery - by day 42 after the infusion of CD3/CD19 depleted, ALT-803 stimulated, donor NK cells and subcutaneous ALT-803 given after a non-myeloablative preparative regimen for the treatment of refractory or released acute myelogenous leukemia (AML)


Secondary Outcome Measures :
  1. Incidence of in vivo expansion ≥100 of donor derived NK cells per uL blood [ Time Frame: Day 14 post NK cell infusion ]
  2. ALT-803 associated toxicity assessment [ Time Frame: Day 0 ]
    Toxicity will be classified and graded according to NCI's Common Terminology Criteria for Adverse Events V 4.0 (CTCAE)

  3. ALT-803 associated toxicity assessment [ Time Frame: Day 5 ]
    Toxicity will be classified and graded according to NCI's Common Terminology Criteria for Adverse Events V 4.0 (CTCAE)

  4. ALT-803 associated toxicity assessment [ Time Frame: Day 7 ]
    Toxicity will be classified and graded according to NCI's Common Terminology Criteria for Adverse Events V 4.0 (CTCAE)

  5. ALT-803 associated toxicity assessment [ Time Frame: Day 10 ]
    Toxicity will be classified and graded according to NCI's Common Terminology Criteria for Adverse Events V 4.0 (CTCAE)

  6. Treatment related mortality [ Time Frame: 6 months post-therapy ]

Ages Eligible for Study:   18 Years to 70 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

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:

    1. For hypomethylating agents (i.e. decitabine, azacititdine) to count as an induction/re-induction attempt, the patient must have completed a minimum of 3 monthly cycles
    2. 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
    3. 7+3 followed by 5+2 counts as TWO induction attempts
    4. Use of hydroxyurea is permitted to control blasts until Day -3 per Section 8.7
    5. 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
