NCT01385423

Brief Summary

This is a single center, "modified standard design" dose escalation study designed to determine the maximum tolerated, minimum efficacious dose (MTD/MED) of IL-15 (Intravenous Recombinant Human IL-15) and incidence of donor natural killer (NK) cell expansion by day +14 when given after haploidentical donor NK cells in patients with relapse or refractory acute myelogenous leukemia (AML).

Outcome Measures

Primary Outcomes (1)

  • Maximum Tolerated/Minimum Efficacious Dose

    Determine the maximum tolerated, minimum efficacious dose (MTD/MED) of recombinant human IL-15; dose limiting toxicity (DLT) occurring during the first 42 days after the NK cell infusion; MED = if 2 of 3 patients or 4 of 6 patients has an in vivo NK cell count \>2500, then dose escalation with cease as it will be in the range of a biologic dose which may achieve the goal of in vivo expansion without pushing IL-15 doses higher to toxicity.

    Day 42

Secondary Outcomes (3)

  • Incidence of Expansion of Natural Killer Cells

    Day 14 after Infusion

  • Treatment Related Mortality (TRM)

    Day 1 of Treatment until Day of Death

  • Rate of CRp

    Day 28-42

Study Arms (1)

IL-15 Patients with AML

EXPERIMENTAL

Adults with Refractory or Relapsed Acute Myelogenous Leukemia (AML) treated with preparative regimen and Intravenous Recombinant Human IL-15 (rhIL-15)

Drug: Preparative RegimenBiological: Intravenous Recombinant Human IL-15 (rhIL-15)

Interventions

Fludarabine 25 mg/m\^2 x 5 days start day -6, Cyclophosphamide 60 mg/kg x 2 days on day -5 and -4 (\*if \< 4 months from prior transplant, omit day -4 dose)

Also known as: Fludara, Cytoxan
IL-15 Patients with AML

IL-15 at assigned dose (0.25, 0.5, 0.75 1, 2 and 3 mcg/kg for 3 to 6 patients) intravenously (IV) over 30 minutes once a day beginning day +1 and continuing for 12 doses

Also known as: IL-15

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • ≥ 18 years of age
  • Meets one of the following disease criteria:
  • Primary acute myelogenous leukemia (AML) induction failure: no complete response (CR )after 2 or more induction attempts
  • Relapsed AML or Secondary AML (from MDS or treatment-related): not in CR after 1 or more cycles of standard induction therapy. For patients \> 60 years of age the 1 cycle of standard chemotherapy is not required if either of the following is met:
  • relapse within 6 months of last chemotherapy
  • blast count \<30% within 10 days of starting protocol
  • AML relapsed \> 2 months after transplant who do not have the option of donor lymphocyte infusions (e.g. recipients of autologous or umbilical cord blood \[UCB\] transplants)
  • Patients with prior central nervous system (CNS) involvement are eligible provided that it has been treated and cerebrospinal fluid (CSF) is clear for at least 2 weeks prior to enrollment. CNS therapy (chemotherapy or radiation) should continue as medically indicated during the study treatment.
  • Available related HLA-haploidentical donor (3-5 of 6 HLA-A, B and C)
  • Karnofsky Performance Status \> 50%
  • Adequate organ function defined as:
  • Creatinine: ≤ 2.0 mg/dL
  • Hepatic: Liver function tests (LFT's) \< 5 times upper limit of institutional normal (ULN)
  • Pulmonary Function: oxygen saturation ≥ 90% on room air and pulmonary function \>50% corrected DLCO and FEV1 Testing required only if symptomatic or prior known impairment.
  • Cardiac Function: Ejection fraction (EF) ≥ 40%, no uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities
  • +3 more criteria

You may not qualify if:

  • Bi-phenotypic acute leukemia
  • Transplant \< 60 days prior to study enrollment
  • 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 within 14 days of study treatment start
  • Active autoimmune disease
  • History of severe asthma, presently on chronic medications (a history of mild asthma not requiring therapy is eligible)
  • New or progressive pulmonary infiltrates on screening chest x-ray or chest CT scan that has not been evaluated with bronchoscopy, if feasible. 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). Surgical resection waives any waiting requirements.
  • Uncontrolled bacterial or viral infections - chronic asymptomatic viral hepatitis is allowed
  • Pleural effusion large enough to be detectable on chest x-ray
  • Known hypersensitivity to any of the study agents used
  • Received investigational drugs within the 14 days before enrollment
  • Known active CNS involvement
  • Criteria For Initial Donor Selection:
  • Related donors (sibling, parent, offspring, parent or offspring of an HLA identical sibling)
  • years of age
  • At least 40 kilogram body weight
  • +6 more criteria
