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 reduced intensity conditioning for children with non-malignant diseases (NMD). This study will have the following Specific Aims:
Specific Aim #1: To conduct a multicenter pilot assessing the tolerability of abatacept (n=10). Patients will receive four doses (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. Abatacept will be combined with cyclosporine and mycophenolate mofetil.
Specific Aim #2: To examine the immunological effects of abatacept in this setting.
Three reduced intensity conditioning regimens that have been shown to be effective in achieving sustained engraftment in patients with non-malignant diseases are available for use, depending on the patient's disease:
- Patients with Fanconi anemia will receive fludarabine, low dose cyclophosphamide, and anti-thymocyte globulin.
- Patients with severe aplastic anemia will receive low dose total body irradiation, fludarabine, cyclophosphamide, and anti-thymocyte globulin.
- Patients with other NMD will receive either the low dose total body irradiation regimen or an alemtuzumab, fludarabine, thiotepa, and melphalan regimen.

Tolerability of Abatacept
Time Frame: 1 year post-transplant

The primary endpoint for this trial will be tolerability, defined in terms of the success in administering all prescribed doses of abatacept. Abatacept will be deemed to be poorly tolerated if any of the following conditions are met:
If less than 4 patients (of at least 18 evaluable patients) tolerate abatacept poorly, abatacept will be deemed tolerable. If there are fewer than 18 evaluable patients, if 3 of the first 10 patients treated tolerate abatacept poorly, abatacept will be deemed tolerable. |
