结局指标
主要结局
Percentage of Participants With Chronic ITP With a Sustained Platelet Count Response Defined as Achieving Platelet Counts of at Least 50×10^9/L for at Least 4 of the 6 Visits Between Week 19 and 24 of the Trial.
时间窗: From Week 19 up to Week 24
Percentage of participants with chronic ITP with a sustained platelet count response was defined as achieving platelet counts of at least 50 × 10\^9/L for at least 4 of the 6 visits between Week 19 and 24 of the study.
次要结局
- Extent of Disease Control Defined as the Number of Cumulative Weeks Over the Planned 24-week Treatment Period With Platelet Counts of ≥50×10^9/L in the Chronic ITP Population(From Week 1 up to Week 24)
- Percentage of Participants With a Sustained Platelet Count Response for at Least 4 of the 6 Visits Between Week 19 and 24 of the Study(From Week 19 up to Week 24)
- Incidence and Severity of the WHO-classified Bleeding Events(From Week 1 to Week 24)
- Percentage of Participants in the Overall Population Achieving Platelet Counts of at Least 50×10^9/L for at Least 6 of the 8 Visits Between Week 17 and Week 24(From Week 17 up to Week 24)
