This clinical trial is a Phase 2/3 study that will evaluate the efficacy and safety of etavopivat and test how well etavopivat works compared to placebo to improve the amount of hemoglobin in the blood and to reduce the number of vaso-occlusive crises (times when the blood vessels become blocked and cause pain).
