A Phase II Trial of Non-Myeloablative Conditioning and Transplantation of Haploidentical Related, Partially HLA-Mismatched, or Matched Unrelated Bone Marrow for Newly Diagnosed Patients With Severe Aplastic Anemia
Medical College of Wisconsin
Summary
BMT CTN 2207 will investigate the use of marrow transplantation for treatment of severe aplastic anemia that has not previously been treated.
Description
This study is a prospective, multicenter Phase II study of hematopoietic stem cell transplantation for previously untreated patients with severe aplastic anemia (SAA). Severe Aplastic Anemia (SAA) is a rare condition in which the body stops producing enough new blood cells. Patients with aplastic anemia have low white blood cells (cells which fight infection), low red blood cells (cells that carry oxygen throughout the body), and low platelets (cells that help form clots and prevent bleeding). Treatments for SAA seeks to repair this abnormal immune system attack and allow the bone marrow to ma…

Interventions
- DrugHaploidentical donor bone marrow transplant
Drugs: 1. Antithymocyte Globulin (ATG) dose will be 0.5 mg/kg IV on Day -9 over 6 hours and 2 mg/kg IV on Days -8 and -7 over 4 hours. 2. Fludarabine dose will be 30 mg/m\^2 IV daily for 5 days from Day -6 to Day -2. 3. Cyclophosphamide dose will be 14.5 mg/kg IV daily for 2 days (Day -6 to Day -5) prior to transplantation and 50 mg/kg IV daily for 2 days (Day +3 to Day +4) after transplantation. 4. Tacrolimus should be started on Day +5 and administered to maintain a level of 10-15 ng/mL. 5. Mycophenolate mofetil (MMF) dose will be 15 mg/kg PO three times a day (TID) up to 1 gm TID (or IV equivalent) starting on Day +5 through Day +35. 6. G-CSF will be given IV or SQ starting on Day +5 at 5 mcg/kg/day until ANC is \> 1500 for 3 days. Radiation: 1\. Total Body Irradiation (TBI): will be given as a single dose of 400 cGy on Day -1. Procedure: 1\. HSCT: Eligible patients will receive a haploidentical donor bone marrow transplant.
