MeasureTime frameDescription
Number of Participants Who Experienced Treatment-emergent Serious Adverse Events (TESAEs)From first dose of trial intervention to end of trial; median (min, max) duration was 52.1 (2.0, 70.1) weeksAn adverse event (AE) was any untoward medical occurrence in a clinical trial participant irrespective of a causal relationship with the study treatment. A SAE was defined as any untoward medical occurrence that meets at least 1 of the following serious criteria: resulted in death (fatal), was immediately life-threatening, required in-patient hospitalization or prolonged existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or other medically important serious event.
