- Subjects on concomitant hydroxyurea must be on a stable dose (mg/kg) for ≥3 months prior to screening Visit V1
- Female subjects of childbearing potential, must have negative pregnancy, must have stopped breastfeeding as of first dose, and must either commit to true abstinence from heterosexual contact or must be willing to use adequate contraceptive precautions.
- Male subjects must practice true abstinence or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential
Exclusion
- Hb level \<6.0 g/dl or \>10.4 g/dl for female participants and \>11.0 g/dl for male participants, at screening Visit V1
- Having received red blood cell (RBC) transfusion therapy within 4 weeks prior to screening, or ongoing or planned RBC transfusion therapy during the course of the study
- Low levels of Ferritin or transferrin saturation or total iron-binding capacity at screening
- Subjects being hospitalized for SCD-related events within 14 days before the screening visit

- Any history or clinically important finding of cardiac or pulmonary disorders
- Family history of long-QT syndrome or sudden death without a preceding diagnosis of a condition that could be causative of sudden death
