Detailed Description
The use of HLA matched sibling donor (MSD) hematopoietic stem cell transplantation (HSCT) for sickle cell disease (SCD) is evolving. Because of the low risk for graft versus host disease (GVHD) associated with younger age, HSCT is increasingly being performed prior to adolescence. The use of less gonadotoxic reduced intensity regimens (RIC) are more commonly be utilized to lessen the risk for infertility. Finally, with the recognition that most children, even those who have asymptomatic to relatively mild courses, will develop debilitating morbidities as adults and ultimately suffer an early death, HSCT is being offered to children across a wider spectrum of SCD severity. Long reserved for severely affected children, HSCT is being performed for a growing number of less severely affected children, as well as children without disease manifestation.
This trial is designed to prospectively assess HSCT under these conditions. Eligibility will be limited to children less than 13 years of age who have an HLA MSD. A RIC regimen - fludarabine, alemtuzumab and melphalan (FAM) - will be employed. Finally, SCD severity criteria will be broadened to include less severely affected children as well as those who are severely affected.
This study has the following two specific aims:
Specific Aim #1: To prospectively assess the safety and efficacy of HSCT using FAM conditioning in children with SCD of varying severity who are under 13 years of age.
Specific Aim #2: To address current gaps in our understanding of the long-term effects of HSCT in children with SCD, by longitudinally assessing sickle cell related cerebrovascular disease, sickle cell related nephropathy and health related quality of life.

Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: Reduced Intensity Conditioning with FAM
Children with SCD will received reduced intensity conditioning with fludarabine, alemtuzumab and melphalan (FAM) during HSCT with a HLA matched sibling donor
|
Fludarabine will be administered at 30 mg/m^2 IV daily for five days (Days -7 to -3).
Other Names:
Melphalan will be administered at 140 mg/m^2 IV on Day -3 following fludarabine administration.
Other Names:
Alemtuzumab will be administered by either subcutaneous (SQ) injection or IV.
A test dose of alemtuzumab, 3 mg, is administered on the first day.
If the test dose is tolerated, administration of three treatment doses will begin within 24 hours.
The three treatment doses will be administered on consecutive days.
On the first day, 10 mg/m2 will be given, 15 mg/m^2 the second and 20 mg/m^2 the third.
Alemtuzumab will be started between Days -22 and -20, but all doses (test dose and three treatment doses) should be completed by Day -18.
