  • {"criterion_text":"- 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."}
  • {"criterion_text":"- 4. Hemoglobin ≥ 5.5 and < 10.5 g/dL"}
  • {"criterion_text":"- 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)."}

  • {"criterion_text":"- 7. Patients on crizanlizumab or L-glutamine treatment at the time of consent may be eligible if they:  Have been on a stable dose for ≥ 12 months at the time of consent (ie, no changes to the dose except for changes to weight or for safety reasons)  For patients on crizanlizumab, have been ≥ 80% compliant with the planned regimen during the 12 months prior to the time of consent"}
