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