  Purpose

The goal of this study is to see if there is a benefit to giving chemotherapy and then natural killer (NK) cells. The NK cells must come from a family member who shares half of the patients HLA proteins. NK cells are a type of white blood cell. They can recognize and kill abnormal cells in the body.

Patients whose blood cancer is not cured with a stem cell transplant do not have standard treatment options. Studies have shown that NK cells from a donor can be given safely and can be helpful in treating some blood diseases. These NK cells are collected from the patients donor and purified using a separation system called CliniMACS that has been used safely in previous studies and is used in this study with the approval of the Federal Food and Drug Administration. The researchers want to find out what effects the NK cells will have on blood cancer and bone marrow function and how to maximize its benefits in treating blood cancers. The researchers hope that giving chemotherapy and then NK cells will be a better treatment for the disease than the current available treatment options.

Arms Assigned Interventions
Experimental: natural killer (NK) cells with salvage chemotherapy
This is a Phase II study, designed to determine the efficacy of natural killer (NK) cells isolated from HLA-haploidentical related donors when infused following a salvage chemotherapy regimen into patients who have relapsed or persistent leukemia following an allogeneic HLA-compatible HSCT and who are ineligible for a second HSCT.
Biological: natural killer cell therapy
The patient must be admitted by Day -8 to the Bone Marrow Transplant Service. On Day 0, patients will receive a single dose of allogeneic NK cells isolated from a HLA-haploidentical related donor and will be monitored for hematopoietic recovery.
Drug: cyclophosphamide
Day -6 cyclophosphamide 60mg/kg infused over 1 hour (dose adjusted for body weight) for 2 days
Drug: fludarabine
Day -5 fludarabine 25mg/m2 CIV for 5 days

Detailed Description:

OBJECTIVES:

Primary

  • Determine the anti-leukemic efficacy of allogeneic HLA-haploidentical related natural killer (NK) cell infusion following a cytoreductive regimen with cyclophosphamide and fludarabine in patients with acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), or blastic CML who have relapsed following allogeneic hematopoietic stem cell transplant, where efficacy is defined as the achievement of complete or partial remission at one year following NK cell infusion.

Secondary

  • To assess treatment efficacy, as defined by achievement of complete or partial remission, at 3 and 6 months following HLA-haploidentical related NK cell infusion.
  • To assess the effects of an HLA-haploidentical related NK cell infusion on the sustained engraftment and recovery of an HLA-matched stem cell allograft.
  • To assess the risk of inducing graft-vs-host disease (GVHD) or altering its severity.
  • To provide preliminary evidence that specific donor KIR-recipient HLA ligand combinations relating to missing self-MHC class I ligand or missing class I ligand are associated with higher NK alloreactivity and improved outcome.
  • To monitor the extent and duration of NK cell donor chimerism.
  • To monitor NK cell reconstitution through NK receptor cell surface phenotyping (CD94/NKG2A, ILT-2, KIR expression) and function (intracellular IFN-γ, cytotoxicity) on day 15, 30, 60, 100, and 200 following the NK infusion and to correlate with outcome.
  • To correlate the magnitude of NK effect with disease and known survival risk factors (time from allogeneic HSCT to relapse; < 6 months vs > 6 months).

Criteria

Subject Inclusion Criteria:

Diagnosis and Status

  • Patients with a pathologically confirmed diagnosis of relapsed or persistent resistant AML, MDS, or blastic CML following HSCT and who have been deemed ineligible for second HSCT after consideration of adequacy of their physical function, extent of disease, and prior treatment-related toxicities.

Eligible patients have evidence of disease with ≥5% bone marrow involvement detected by morphology or abnormal cytogenetics (by karyotype or FISH). Patients with molecular detection of markers characteristic of the patient's disease from two consecutive bone marrow biopsies are also eligible. Following diagnosis of relapsed disease, treatment to reduce leukemic burden is allowed prior to protocol therapy without the need for additional disease documentation prior to cyclophosphamide and fludarabine.

  • Patients with extramedullary relapse are eligible except for those with CNS involvement.
  • Patients must have received an allogeneic HSCT.
  • Patient must not be pregnant and must be using adequate form of birth control.
  • Patients must have a Karnofsky (adult) or Lansky (pediatric) Performance Status ≥ 60%.
  • Hospitalization does not preclude enrollment, as long as the patient's performance status is ≥ 60% according to the KPS grading scale.
  • Patients must have adequate physical function measured by :

Cardiac: asymptomatic and LVEF at rest must be > 50%. Hepatic: < 2x ULN ALT and < 1.5 total serum bilirubin, unless liver is involved with disease, there is congenital benign hyperbilirubinemia, or other reversible causes of hepatic abnormalities are documented.

Renal: serum creatinine <1.5 mg/dl or if serum creatinine is outside the normal range, then CrCl > 50 ml/min Pulmonary: Patient cannot be oxygen-dependent.

  • Patients with documented GVHD are not excluded from this trial, but either must not have used systemic immunosuppression for two weeks, or during immunosuppression taper have documented two subtherapeutic levels at least one week apart. Immunosuppressive agents include but are not limited to systemic steroids, calcineurin inhibitors, MTOR-inhibitors, Budesonide, anti-thymocyte globulin. The maximal allowable dose of corticosteroids is the equivalent of 10 mg/day prednisone.
  • Patients with grade I/II acute GVHD or limited chronic GVHD and receiving localized GVHD therapy (e.g. topical steroids) are not excluded from this trial.
  • Patients having received previous adoptive cellular therapy such as donor lymphocyte infusion (DLI) are not excluded from this trial as long as their disease has been documented to progress within two months of receiving DLI or if the patient has not received DLI within two months of NK cell infusion.
  • Patients who have received cytoreductive therapy following documentation of relapse and prior to enrollment are not excluded from this trial. The interval between standard reinduction chemotherapy and start of protocol chemotherapy should be a minimum of 2 weeks, and all induction chemotherapy-related toxicities should be documented to be completely resolved. For patients receiving nonintensive chemotherapies such as hydroxyurea or low-dose cytarabine, nonintensive chemotherapies should be discontinued upon initiation of protocol chemotherapy.
  • Each patient must be willing to participate as a research subject and must sign an informed consent form. Parents or legal guardians of patients who are minors may sign the informed consent form
  • Patients must have an eligible NK donor.
  • There are no age restrictions to this protocol.

NK Cell Donor Eligibility
