- Hemoglobin response rate at Week 24 (increase of > 1 g/dL [> 10 g/L] from baseline) during the blinded treatment period [ Time Frame: 24 Weeks ]
- Annualized vaso-occlusive crisis rate during the 52-week blinded treatment period based on adjudicated vaso-occlusive crisis review [ Time Frame: 52 Weeks ]
- Change from baseline in hemoglobin at Week 24 during the blinded treatment period [ Time Frame: 24 Weeks ]
- Change in Sickle Cell Disease related clinical laboratory measurements from baseline at Week 24 during the blinded treatment period [ Time Frame: 24 Weeks ]
- % reticulocytes,
- Unconjugated bilirubin
- Lactate dehydrogenase (LDH)
- Time to first vaso-occlusive during the blinded treatment period [ Time Frame: 52 Weeks ]
- Change from baseline in Patient-Reported Outcome Measurement Information System (PROMIS) Fatigue Scale at Week 24 during the blinded treatment period [ Time Frame: 24 Weeks ]Adult patients (ages 18 to 65) will complete the PROMIS® Item Bank v.1.0 - Fatigue - Short Form 7a. Adolescent patients (ages 12 to 17) will complete the PROMIS® Item Bank v2.0 - Fatigue - Short Form 10a. Responses are graded on a score of 1 to 5 with a higher score indicating a worse outcome.
