Brief Summary:
Our primary objective is to determine if it is feasible for previously untreated severe aplastic anemia (SAA) patients to be transplanted using non-myeloablative conditioning and post transplantation cyclophosphamide.

Condition or disease Intervention/treatment Phase
Severe Aplastic Anemia Aplastic Anemia Bone Marrow Failure Immunosuppression Drug: Thymoglobulin Drug: Fludarabine Drug: Cyclophosphamide Radiation: Total body irradiation Drug: Tacrolimus Drug: Mycophenolate mofetil Phase 2

Detailed Description:
This is a clinical trial of upfront bone marrow transplantation for patients with SAA who do not have a fully human leukocyte antigen (HLA) matched donor. The trial uses a conditioning regimen which has been successful in the refractory and relapsed setting to maximize engraftment and post transplant therapy to minimize graft versus host disease (GVHD). This would be used here in patients who have not yet undergone immunosuppressive therapy for their SAA or are thought to be unlikely to respond to immunosuppressive therapy for SAA.

Ages Eligible for Study:   Child, Adult, Older Adult
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Confirmed diagnosis of inherited or acquired severe aplastic anemia (SAA)
  • One of the following available donors:

    1. HLA-haploidentical relative
    2. If recipient is >= 40 years old, may use HLA-matched related donor
    3. For recipients with inherited bone marrow failure syndromes (IBMFS) with clear evidence of same disorder in potential related donors, may use 10/10 matched unrelated donor
  • Recipient and/or legal guardian must sign protocol informed consent
  • Donor must be willing to donate bone marrow
  • Left ventricular ejection fraction (LVEF) >= 40%. For recipients < 13 years old, shortening fraction >= 26% may be used instead.
