This is a randomized, open-label multicenter pilot study comparing two dose numbers of abatacept. The study is assessing the tolerability of 4 and 6 doses of abatacept when combined with cyclosporine and mycophenolate mofetil as graft versus host disease prophylaxis in children undergoing unrelated hematopoietic stem cell transplant for serious non-malignant diseases.

Detailed Description:

Allogeneic hematopoietic stem cell transplantation (HSCT) represents the only viable cure for children who suffer from a wide variety of rare, serious non-malignant diseases, such as Fanconi Anemia, Hurler syndrome, and hemophagocytic lymphohistiocytosis. A major obstacle to the success of HSCT is morbidity and mortality from graft versus host disease (GVHD), driven by donor T cells recognizing and reacting against disparate host antigens. This trial is being conducted as a step toward testing the long-term hypothesis that the costimulation blockade agent abatacept can be added to a standard post-transplant GVHD prophylaxis regimen, cyclosporine and mycophenolate mofetil, to improve disease-free survival after unrelated hematopoietic stem cell transplantation (HSCT) using low dose total body irradiation based conditioning for children with non-malignant diseases. This study will have the following Specific Aims.

Specific Aim #1: To conduct a randomized, open-label multicenter pilot, assessing the tolerability of two dose numbers of abatacept (n=20). Patients will be randomly assigned to receive four doses (arm A;10 mg/kg IV on days -1, +5, +14 and +28), a schedule well tolerated by adolescents and adults with hematologic malignancies in a previous pilot, or six doses (arm B;10 mg/kg IV on days -1, +5, +14, +28, +56 and +84). Abatacept will be combined with cyclosporine and mycophenolate mofetil.

Specific Aim #2: to compare the immunological effects of four and six doses.


Ages Eligible for Study:   up to 21 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Must be between the ages of 0-21 years at the time of admission for transplant.
  • Must have one of the following diseases:

    1. Glanzmann thrombasthenia
    2. Wiskott-Aldrich syndrome or other combined immune deficiency
    3. Chronic-granulomatous disease
    4. Severe congenital neutropenia
    5. Leukocyte adhesion deficiency
    6. Shwachman-Diamond syndrome
    7. Diamond-Blackfan anemia (transfusion dependent)
    8. Thalassemia major
    9. Fanconi anemia
    10. Hemophagocytic lymphohistiocytosis
    11. Dyskeratosis-congenita
    12. Hurler Syndrome
    13. Chediak-Higashi syndrome
    14. Acquired (immune; non-inherited, non-congenital) severe aplastic anemia
    15. Other inherited or congenital marrow failure syndromes complicated by severe aplastic anemia
    16. Other inherited or congenital red blood cell disorders requiring monthly chronic transfusion therapy.
    17. Congenital platelet disorders requiring frequent platelet transfusions (patient must have received at least 10 transfusions in the last 3 years).
    18. Other inherited or congenital granulocyte disorders resulting in at least three inpatient hospitalizations in the past three years for infection.
  • Must have an unrelated adult donor (marrow or PBSC) who is matched at least seven of eight HLA alleles (A, B, C, DRB1; the mismatch can be at an allele or antigen level)* or an unrelated cord blood unit that is matched at least seven of eight loci (A, B and C antigen level-DRB1 allele level) and provides a minimum pre-cryopreservation TNC dose of 7.5 x 107 TNC/kg recipient weight. Mismatches at the DRB1 locus may be at an antigen or allele level.

Exclusion Criteria:

  • Human leukocyte antigen (HLA) matched related donor
  • Severe combined immune deficiency.
  • Sickle cell disease.
  • Biopsy proven cirrhosis.
  • Pulmonary: Diffusing capacity of lung for carbon monoxide (corrected for hemoglobin), forced expiratory volume at one second or forced vital capacity < 40% of predicted. In child unable to perform pulmonary function testing, a chronic need for supplemental oxygen will serve as the exclusionary criterion.
  • Severe renal dysfunction defined as estimated glomerular filtration rate of <30 ml/min.
  • Severe cardiac dysfunction defined as shortening fraction < 25%.
  • Karnofsky or Lansky functional performance score < 50%
  • HIV infection.
  • Uncontrolled viral, bacterial, fungal or protozoal infection at the time of study enrollment.
  • Patient with unspecified chronic toxicity serious enough to detrimentally affect the patient's capacity to tolerate bone marrow transplantation.
  • Patient or patient's guardian(s) unable to understand the nature and risks inherent in the blood and marrow transplant process.
  • History of lack of compliance with medical care that would jeopardize transplant course.
  • Patient is pregnant or lactating
  • Patients HLA antibody testing (see below) demonstrates an antibody directed against a disparate HLA molecule.
