结局指标
主要结局
Percentage of Participants With Treatment-emergent AEs or Serious Adverse Events (SAEs)
时间窗: 24 months
An AE was any untoward, undesired, or unplanned clinical event in the form of signs, symptoms, disease, or laboratory or physiologic observations occurring in a person given study drug or in a sponsor's clinical study. The event did not need to be causally related to the study drug or the clinical studies. A treatment emergent AE was defined as an event that emerged during the treatment period that was absent before treatment, or worsened during the treatment period relative to the pretreatment state. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
