About the study

This study is being done to determine the safety and outcome (long-term control) of a
high-dose chemotherapy regimen followed by an infusion of CD34 selected (immune cells) stem
cells from a partially matched adult family member donor, called haploidentical stem cell
transplantation, in high-risk sickle cell disease patients.

Funding Source – FDA OOPD

participation requirements

– Homozygous Hemoglobin S Disease, or Hemoglobin S Beta0/+ thalassemia

– Patients must demonstrate one or more of the following Sickle Cell Disease

1. Clinically significant neurologic event (stroke) or any neurologic deficit
lasting >24 hours that is accompanied by an infarct on cerebral MRI

2. Minimum of two episodes of acute chest syndrome.

3. Recurrent painful events (at least 3 in the 2 years prior to enrollment).

4. Abnormal TCD study requiring starting on chronic transfusion therapy.

5. At least one silent infarct lesion on a MRI scan of the head.

– A familial haploidentical donor without homozygous sickle cell disease

– Adequate organ function (renal, liver, cardiac and pulmonary function)

– Karnofsky or Lansky (age appropriate) Performance Score ≥50%

– Liver biopsy is optional to assess for iron overload in chronically transfused

participation restrictions

– Females who are pregnant or breast-feeding

– SCD Patients with documented uncontrolled infection

– SCD patients who have an unaffected HLA matched family donor willing to proceed to

– Karnofsky/Lansky (age appropriate) Performance Score <50% (hemiplegia alone secondary to a previous stroke is not an exclusion) - Demonstrated lack of compliance with medical care. - Clinically significant fibrosis or cirrhosis of the liver - Previously received a HSCT
