Decitabine and Vorinostat Conditioning Followed by CD3-/CD19- NK Cells Infusion for High Risk Myelodysplastic Syndromes

This study is ongoing, but not recruiting participants.

Last updated: January 22, 2016
Last verified: January 2016
This is a Phase II therapeutic trial combining Decitabine days 1-5 with oral Vorinostat twice daily days 6-15 followed by a single infusion of CD3-/CD19- enriched donor natural killer (NK) cells on day 17 and a short course of Interleukin-2 (IL-2) to facilitate NK cell survival and expansion. Two courses of treatment will be given separated by 6-8 weeks. The intent is to administer all treatment in the outpatient setting.

Primary Outcome Measures:
  • Objective Response Rate [ Time Frame: After 2 Courses of Treatment (Approx. 3 months) ]
    Defined as Complete response (CR) + partial response (PR) + hematologic improvement (HI).

Secondary Outcome Measures:
  • Safety and Tolerability [ Time Frame: Day 1 through Month 3 ]
    Assess the safety and tolerability of Decitabine and Vorinostat followed by an infusion of CD3-/CD19-donor natural killer (NK) cells and a short course of IL-2 when given in the outpatient setting in patients with high risk myelodysplastic syndrome (MDS).

  • Number of Patients Who Became Transfusion Independent [ Time Frame: 4-6 Months Post Start of Cycle 1 ]
  • Natural Killer Cell Expansion [ Time Frame: After Cycle 2 (approx. 3 months) ]
    Defined as patients with in vivo expansion.

  • Overall Survival [ Time Frame: 1 Year ]
    Patients alive at 1 year.

Enrollment: 9

Arms Assigned Interventions
Experimental: Patients With High Risk MDS
Patients who received treatment for high risk myelodysplastic syndromes (MDS). Treatment Received: Decitabine 10 mg/m^2/day intravenous (IV) over 1 hour days 1-5; Vorinostat 200 mg by mouth (PO) twice a day days 6-15; Il-2 activated donor natural killer cells (NK) infusion IV over 15 to 60 minutes day 17; Interleukin-2 6 million units subcutaneous (SQ) 3 times a week for 3 doses beginning day 17. Repeat treatment course 6 to 8 weeks after cycle 1 start date.
Drug: Decitabine
administered intravenous (IV), 10 mg/m^2/day over 1 hour on days 1-5.
Other Name: Dacogen
Drug: Vorinostat
200 mg by mouth (PO) twice a day on days 6-15
Other Name: Zolinza
Biological: Interleukin-2
6 million Units subcutaneous (SQ) 3 times a week for 3 doses beginning day 17
Other Name: IL-2
Other: Natural killer (NK) cells
infusion intravenously (IV) over 15 to 60 minutes day 17

Detailed Description:

A single donor apheresis will be collected on day 15 of cycle 1, enriched for NK cells with the large scale CliniMacs device (Miltenyi) and activated by overnight incubation with IL-2. After washing, the final NK cell product will be divided in two, with half given fresh on day 17 of course #1 and half stored frozen until day 17 of course #2.

Clinical response will be formally assessed 4-6 weeks after the start of 2nd course based on International Working Group (IWG) criteria; however, bone marrow evaluations will be completed to assess for any sign of significant disease progression between cycle 1 and 2.


Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of high risk myelodysplastic (MDS) that meets one of the following disease classifications and is requiring treatment:

    • International Prognostic Scoring System (IPSS) Category: INT-2 or High Risk
    • WHO Classification: RAEB-1 or RAEB-2
    • High risk cytogenetic abnormality as defined by presence of Monosomy 7, complex karytope, or monosomal karyotype
    • WHO Based Prognostic Scoring System (WPSS): High or Very High Risk
  • Patients may be untreated or have had a maximum of 2 cycles of hypomethylating agents (azacitidine or decitabine) without evidence of treatment failure as defined by progression to more advanced MDS Who classification or AML. Patients must not have received treatment for their MDS within 4 weeks of beginning the trial. Treatments allowed prior to that time include azacitidine or decitabine and hematopoietic growth factors. No prior AML-like induction therapy allowed.
  • Age ≥ 18 years of age
  • Eastern Cooperative Oncology Group (ECOG) Performance Status 0-2
  • Available related HLA-haploidentical NK cell donor by at least Class I serologic typing at the A&B locus

  • Ability to be off prednisone and other immunosuppressive drugs for at least 3 days prior to the natural killer (NK) cell infusion
  • Women of child bearing potential must agree to use effective methods of contraception
  • Voluntary written consent

  • New progressive pulmonary infiltrates on screening chest x-ray or chest computed tomography (CT) scan that has not been evaluated with bronchoscopy (when feasible)
  • Uncontrolled bacterial or viral infections - chronic asymptomatic viral hepatitis is allowed
  • Pleural effusion moderate to large in size that are detectable on chest xray
  • Known hypersensitivity to one or more of the study agents
