An adverse event (AEs) was any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE was considered a TEAE if the event started during the effective duration of treatment. All events that start on or after the first dose of study intervention, but before the end of the study were flagged as TEAEs. Serious AE (SAE) was defined as any untoward medical occurrence that, at any dose, meets one or more of the criteria: death, life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, congenital anomaly or birth defect. AEs included SAEs and non-SAEs.
