You may be eligible if
1. Be ≥ 5-30 years of age.
2. Have a diagnosis of SCD, with either βS/βS, βS/β0, βS/β+ or βS/βC genotype and followed at a center of excellence for SCD with at least 2 years of detailed past medical records available.
3. Have severe disease i.e. have experienced one or more of the following SCD related events, in spite of appropriate supportive care measures (e.g. pain management, penicillin prophylaxis):
1. Recurrent severe vaso-occlusive crisis (VOC) (≥2 episodes/year in the prior 2 years): an episode of pain lasting \>2 hours severe enough to require care at a medical facility. Note that priapism that lasts \>2 hours and requires care at a medical facility is also considered a VOC. To meet this criterion, subjects must have either experienced hydroxyurea failure at any point in the past (defined as \>1 VOC or ≥1 acute chest syndrome (ACS) after taking hydroxyurea for ≥3 months) or must have intolerance to hydroxyurea (defined as inability to be maintained on an adequate dose of hydroxyurea due to marrow suppression or severe drug-induced toxicity \[e.g. gastrointestinal distress, fatigue\]).
2. ACS (≥2 total episodes in the prior 2 years, with at least one episode in the past year), defined as an acute event with pneumonia-like symptoms, hypoxemia and the presence of a new pulmonary infiltrate. To meet this criterion, subjects must have either experienced hydroxyurea failure or have intolerance to hydroxyurea, as defined above.
3. History of an overt stroke, defined as a sudden onset neurologic deficit lasting more than 24 hours that is accompanied by cerebral MRI changes.
4. patients on chronic transfusions are eligible, provided medical records documenting any of the above severity criteria are available prior to starting the transfusion program.
4. Availability of 1 CB unit ≥ 6/8 HLA match (when A, B, C and DRB1 are performed at the allelic level resolution) with of at least CD34+ cell count 1.5 x 105/kg and total nucleated cells (TNC) 1.5 x 107/kg (pre-freeze)
5. Have adequate organ function to undergo a myeloablative (reduced toxicity conditioning) HSCT.
6. Have a Lansky/Karnofsky performance status of ≥ 80.
7. An appropriate and willing HLA-matched sibling donor is not available.
You may not be if
1. Prior HSCT or gene-therapy.
2. Positive for presence of HIV-1 or HIV-2, hepatitis B virus (HBV), or hepatitis C virus (HCV). (Note that patients who have been vaccinated against hepatitis B \[hepatitis B surface antibody (HBsAb)-positive\] or patients with positive hepatitis B core and/or hepatitis B-e antibodies are also eligible provided viral load is negative by quantitative polymerase chain reaction (qPCR). Patients who are positive for anti-hepatitis C antibody are eligible as long as they have a negative HCV viral load by qPCR). Positive serology for human T-lymphotropic virus-1 (HTLV-1), syphilis (rapid plasma reagin (RPR)), toxoplasmosis.
3. Clinically significant and active bacterial, viral, fungal, or parasitic infection as determined by PI.
4. A white blood cell count \<2 × 10e9/L, and/or platelet count \<50 × 10e9/L.
5. Any prior or current malignancy or myeloproliferative or a significant coagulation or immunodeficiency disorder.
6. Advanced liver disease, defined as:
1. Persistent aspartate transaminase, alanine transaminase, or direct bilirubin value \>5 times the upper limit of normal (ULN); or
2. Cirrhosis or bridging fibrosis; or
3. Baseline prothrombin time or partial thromboplastin time \> 1.5 x ULN; or
4. in chronically transfused patients a liver iron concentration (LIC) of ≥ 15 mg/g on T2\* Magnetic Resonance Imaging \[MRI\] of liver.
7. Left ventricular ejection fraction (LVEF) \<45% and for patients on chronic transfusions a cardiac T2\* \< 10 ms by MRI.
9. Baseline oxygen saturation \< 85% without supplemental oxygen (excluding periods of SCD crisis or infection).
10. Diffusion capacity of carbon monoxide (DLCO) \<50% of predicted (corrected for hemoglobin and/or alveolar volume).
11. Any contraindication to general anaesthesia.
12. Participation in another clinical study with an investigational drug within 30 days of Screening.
13. Diagnosis of a significant psychiatric disorder as deemed as the PI that could seriously impede the subject's ability to participate in the study.
14. Pregnancy or breastfeeding in a postpartum female or absence of adequate contraception for fertile patients. Females of child bearing potential are required to use effective contraception from enrollment through at least 6 months after drug product infusion. Male patients are required to use effective contraception from enrollment through at least 6 months after drug product infusion.
15. An assessment by the PI that the subject would not comply with the study procedures outlined in the protocol.
16. Any abnormal condition or laboratory result that is considered by the PI capable of altering patient condition or study outcome.
