Eligibility Criteria
You may qualify if:
- The following criteria are established to identify subjects with sickle cell disease (SCD) who have a high predicted morbidity and are at risk for early mortality. Subjects with S/S disease, S/C disease, Hemoglobin H disease, Alpha Thalassemia Major, Thalassemia Major (also known as Cooley's anemia) or S/B\* thalassemia and one or more of the following medical complications will be eligible:
- History of impaired neurological function and/or findings on Magnetic Resonance Image (MRI)/Magnetic Resonance Angiogram (MRA) that are associated with sickle cell disease
- More than 1 episode of acute chest syndrome with stage I or II pulmonary disease
- Osteonecrosis involving ≥ 2 joints
- Sickle cell nephropathy as evidenced by a glomerular filtration rate of 30% - 50% of the predicted normal
- Alloimmunization that is sufficient to interfere with the efficacy of chronic transfusion therapy
- Chronic or recurrent priapism
- Major visual impairment in one or both eyes with bilateral proliferative retinopathy
- Persistent disabling pain (≥ 2 episodes per year) despite trials of chronic transfusion and/or hydroxyurea at recommended doses for at least 6 months duration
- Additional General Criteria:
- Subjects must have a related donor (identical or mismatched for 1, 2 or 3 HLA- A, HLA-B or HLA-DR loci).
- Subjects must have adequate cardiopulmonary function as documented by a left ventricular ejection fraction ≥ 50% (or within normal limits per Institutional criteria) or a left ventricular shortening fraction Within normal limits (WNL) per Institutional criteria, without inotropic support. If Ejection fraction is 40-50%, the patient may be considered for participation if cleared by a Cardiologist.
- Subjects must have adequate pulmonary function as documented by Diffusing capacity of the lung for carbon monoxide (DLCO) and Forced expiratory volume in 1 second (FEV1)
- % predicted for age and size. If DLCO and FEV1 are between 40-50%, patient may be considered for participation if cleared by a Pulmonologist.
- Subjects must have adequate hepatic function as demonstrated by a serum albumin ≥ 3.0 mg/dL, and serum glutamic pyruvic transaminase (SGPT) or serum glutamic oxaloacetic transaminase (SGOT) ≤ 2.5 times the upper limit of normal.
- +3 more criteria
You may not qualify if:
- Uncontrolled infection or severe concomitant diseases, which in the judgment of the Principal Investigator, could not tolerate transplantation.
- Severe impairment of functional performance as evidenced by a Karnofsky (patients ≥16 years old) or Lansky (children \<16 years old) score \<70%
- Stage III or IV sickle cell pulmonary disease
- Renal insufficiency (GFR \< 25% of predicted normal for age)
- Subjects with a positive human immunodeficiency virus (HIV) antibody test result
- Subjects who are pregnant, as indicated by a positive serum human chorionic gonadotrophin (HCG) test
- Subjects of childbearing potential who are not practicing adequate contraception as defined by the investigator at the site
- Subjects must not have had previous radiation therapy that would preclude total body irradiation (as determined by a radiation oncologist).
