Phase 2a: Proportion of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), and AEs Leading to Discontinuation During the Core Period
時間枠:Up to 16 weeks

An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. An SAE is any AE or suspected adverse reaction that results in death, is immediately life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, results in congenital anomaly/birth defect, or is considered an important medical event.

Up to 16 weeks
Phase 2a: Proportion of Participants With Hb 1.0+ Response
時間枠:Baseline, Week 8 through Week 16

Hb 1.0+ response is defined as a ≥1.0-g/dL increase from baseline in the average Hb concentration from Week 8 through Week 16

Baseline, Week 8 through Week 16
Phase 2b: Proportion of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), and AEs Leading to Discontinuation During the Core Period
時間枠:Up to 24 weeks

An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. An SAE is any AE or suspected adverse reaction that results in death, is immediately life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, results in congenital anomaly/birth defect, or is considered an important medical event.

Up to 24 weeks
Phase 2b: Duration of Transfusion Independence (TI)
時間枠:Baseline up to 24 weeks

The duration of TI will be calculated as the number of days in the longest transfusion-free period starting on or after the start of study treatment through the end of the Core Period.

Baseline up to 24 weeks
