Who can take part
You may be able to join if
- 1. Patient’s parent, legal guardian, or legal representative has provided documented informed consent and patients have provided age-appropriate assent
- 2. Age > 6 months and < 18 years of age at time of enrollment, according to the enrolling cohort: Cohort 1: age 12 to < 18 years (adolescents) Cohort 2: age 6 to < 12 years Cohort 3: age 2 to < 6 years Cohort 4: age 6 months to < 2 years
- 3. Patient has confirmed diagnosis of SCD Documentation of SCD genotype (HbSS, HbSβ0-thalassemia or other sickle cell syndrome variants) based on prior history of laboratory testing. Molecular genotyping is not required. SCD genotype may be determined from the results of Hb electrophoresis, high-performance liquid chromatography (HPLC), or similar testing. Note that Hb electrophoresis or HPLC is performed by the local laboratory at Screening.
- 4. Hemoglobin ≥ 5.5 and < 10.5 g/dL
- 5. Pediatric patients with severe SCD, as defined by at least 1 of the following: 2-15 episodes of documented VOC (defined in Section 8.4.2) within the 12 months prior to screening. Documentation must exist in the patient’s medical record prior to screening. Events based solely on patient recall without supporting documentation should not be counted towards eligibility. Hospitalization for any SCD-related complication in the last 12 months prior to starting study treatment Proteinuria, defined as an albumin:creatinine ratio (ACR) > 100 mg/g on 2 measures (separated by ≥ 1 month) as an indicator of early renal disease History of a conditional TCD in the last 12 months prior to starting study treatment, but not currently being treated with chronic transfusion therapy (applicable to participants > 2 years of age). Conditional TCD is defined as a TAMMV of 170-199 cm/s by TCD or 155-184 cm/s by imaging TCD (TCDi).
- 6. For participants taking HU, the dose of HU (mg/kg) must be stable (no more than a 20% change in dosing) for at least 90 days prior to start of study treatment with no anticipated need for dose adjustments during the study, in the opinion of the investigator
You likely can't join if
- 1. Female who is breastfeeding or pregnant
- 10. Receipt of prior cellular based therapy (e.g., hematopoietic cell transplant, gene modification therapy)
- 2. More than 15 VOCs (as defined in Section 8.4.2) within the 12 months prior to starting study treatment that required a hospital, emergency room (ER), or clinic visit
- 3. Hospitalized for sickle cell crisis or other vaso-occlusive event occurring in the 14 days prior to starting study treatment
- 4. Abnormal TCD in the 12 months prior to starting study treatment
- 5. Patients receiving regularly scheduled blood (RBC) transfusion therapy (also termed chronic, prophylactic, or preventive transfusion)
