Experimental: INCB059872 0.5 mg
INCB059872 0.5 mg tablet administered orally every other day (QOD) for 28 days on an empty stomach. If dose was well tolerated, once daily (QD) administration was evaluated independently and in parallel with QOD administration.

- Safety and tolerability of INCB059872 assessed by monitoring frequency, duration, and severity of adverse events [ Time Frame: Screening through 35 days after end of treatment, up to approximately 3 months per participant. ]An adverse event is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurs after a participant provides informed consent.
- Change in fetal hemoglobin (HbF) from baseline [ Time Frame: Baseline through 2 weeks after end of treatment, up to approximately 2.5 months per participant. ]Pharmacodynamic activity assessed by measuring changes of HbF from baseline and their correlation to INCB059872 treatment. The HbF (F cells) in human whole blood will be characterized using flow cytometry.
- Cmax of INCB059872 [ Time Frame: Baseline to Day 28. ]Defined as maximum observed plasma concentration.
- AUC0-t of INCB059872 [ Time Frame: Baseline to Day 28. ]Defined as area under the single-dose plasma concentration-time curve from Hour 0 to the last quantifiable measurable plasma concentration.
