RATIONALE: A bone marrow or umbilical cord blood transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. Giving combination chemotherapy before a donor stem cell transplant may make the transplant more likely to work. This may be an effective treatment for patients with high risk Fanconi's anemia.
PURPOSE: This clinical trial is studying how well combination chemotherapy works in treating high risk patients who are undergoing a donor stem cell transplant for Fanconi's anemia.
|Condition or disease||Intervention/treatment||Phase|
|Fanconi Anemia||Biological: anti-thymocyte globulin Biological: filgrastim Drug: busulfan Drug: cyclophosphamide Drug: fludarabine phosphate Drug: methylprednisolone Biological: Hematopoietic stem cell transplantation||Phase 2|
- Determine whether the incidence of neutrophil engraftment is acceptable in high-risk patients with Fanconi's anemia treated with busulfan, cyclophosphamide, fludarabine, and antithymocyte globulin followed by allogeneic hematopoietic stem cell transplantation.
- Determine the tolerability of mycophenolate mofetil in these patients.
- Determine the incidence of acute and chronic graft-vs-host disease in patients treated with this regimen.
- Determine the incidence of major infections in patients with a history of major infections treated with this regimen.
- Determine the incidence of relapse in patients with refractory anemia with excess blasts, refractory anemia with excess blasts in transformation, or acute myeloid leukemia treated with this regimen
- Determine the probability of 1-year survival of patients treated with this regimen.
OUTLINE: Patients are stratified according to donor/recipient HLA type (identical vs other).
- Cytoreductive combination chemotherapy: Patients receive busulfan intravenously (IV) over 2 hours twice daily on days -7 and -6 and cyclophosphamide IV over 2 hours and fludarabine IV over 30 minutes once daily on days -5 to -2.
- Graft failure prophylaxis: Patients receive methylprednisolone IV twice daily on days -5 to 30 and anti-thymocyte globulin IV over 4-6 hours twice daily on days -5 to -1.
- Graft-vs-host disease prophylaxis: Patients receive cyclosporine IV over 2 hours twice daily on days -3 to 100 (if patient has a matched sibling donor) or days -3 to 180 (if patient has another donor type). Patients also receive mycophenolate mofetil orally or IV twice daily on days -3 to 45.
- Allogeneic hematopoietic stem cell transplantation (HSCT): Patients undergo allogeneic HSCT (using bone marrow or umbilical cord blood) on day 0. Patients receive filgrastim (G-CSF) subcutaneously beginning on day 1 and continuing until blood counts recover.
After completion of study treatment, patients are followed periodically for 3 years.
