ListOutcomeTime frameDescription
PrimaryNumber of Participants Who Experienced Treatment Emergent Adverse Events (TEAEs), Serious TEAEs and TEAEs Leading to DeathBaseline (Day 1 of current study) to end of study (Week 218)
An AE was defined as any untoward medical occurrence in a participant administered a study drug which may or may not have a causal relationship with the study drug. Treatment- emergent adverse events (TEAEs) were defined as AEs that developed or worsened or became serious during on- treatment period (time from the first dose of study drug to the last dose of study drug plus 70 days). A serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in any of the following outcomes: death, life- threatening, required initial or prolonged in-patient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or considered as medically important event. Any TEAE included participants with both serious and non-serious AEs.
