结局指标
主要结局
Number of Participants With 28-Day All-cause Mortality
时间窗: 28 days
28-Day All-cause Mortality
Number of Participants With On-Treatment Serious Major Bleeding Events
时间窗: Through Study Day 28
On-treatment Serious Major Bleeding Events collected as Serious Adverse Events and defined as: any intracranial hemorrhage, any life-threatening bleeding, any bleeding event classified as serious by the Investigator (e.g., resulting in permanent morbidity), or any bleeding that required the administration of 1440 ml (typically 6 units) of packed red cells over two consecutive days. (Investigator assessment for seriousness criteria.)
次要结局
- Follow up All-cause Mortality at 3 Months(3 months)
- Number of Event Free and Alive Days to Measure Resolution of Organ Dysfunction(28 days)
- Number of Participants With Anti-drug Antibodies(18 months)
