Stem Cell Transplantation After Reduced-Dose Chemotherapy for Patients With Sickle Cell Disease or Thalassemia
Study Details
Study Description
Brief Summary
The purpose of this study is to find out if using a lower dose of chemotherapy before stem cell transplantation can cure patients of sickle cell anemia or thalassemia while causing fewer severe side effects than conventional high dose chemotherapy with transplantation.

Detailed Description
Hemoglobinopathies, such as sickle cell disease and thalassemia major, are genetic diseases associated with significant morbidity and premature death. Allogeneic bone marrow transplantation (BMT) is the only potential cure for severe hemoglobinopathies. Typical regimens have used high doses of chemotherapy or chemo-radiotherapy to ablate recipient hematopoiesis and to prevent graft rejection. The widespread use of this treatment has been limited by toxicity, risk of end-organ damage, and donor availability. This study will use a nonmyeloablative regimen of fludarabine and busulfan to attempt to generate consistent engraftment with donor hematopoietic stem cells in patients with severe hemoglobinopathy.
G-CSF mobilization of the donor's peripheral blood white blood cells will precede donor apheresis. A nonmyeloablative conditioning regimen of fludarabine and busulfan will be administered to patients prior to allogeneic peripheral blood stem cell infusions. FK506 and prednisone will be administered for graft versus host disease (GVHD) prophylaxis. Patients will be evaluated for engraftment, donor: host hematopoietic chimerism, toxicity, and hemoglobinopathy.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Allogeneic stem cell transplantation Participants will receive a nonmyeloablative conditioning regimen of fludarabine and busulfan prior to allogeneic peripheral blood stem cell (CD34+) infusions. FK506 and prednisone will be administered for graft versus host disease (GVHD) prophylaxis. |
Drug: Busulfan
0.8 mg/kg/d administered as a single intravenous infusion over 3 hours for 4 days. All infusions are anticipated to be given in the outpatient clinic.
Other Names:
Drug: Fludarabine
30 mg/m^2/d administered as a bolus infusion over 30 minutes for 4 days. All infusions are anticipated to be given in the outpatient clinic.
Other Names:
Drug: FK506
0.15 mg/kg taken orally daily for 12 to 14 weeks
Other Names:
Drug: Prednisone
0.5 mg/kg taken orally four times daily on Day 7 and increase to 1 mg/kg taken orally four times daily on Day 14. Participants will continue regimen until Day 30 before a 20-25% taper per week.
