Outcomes
Primary Outcomes
Number of Participants With Serious Adverse Events (SAE) and Treatment-Emergent Adverse Events (TEAE)
Time Frame: From Day 1 up to final follow-up (Day 123)
A SAE was any adverse experience occurring at any dose that resulted in any of the following outcomes: Death, Life-threatening experience, required inpatient hospitalization or prolongation of existing hospitalization. Resulted in persistent or significant disability or incapacity. Was a congenital anomaly or birth defect. Was considered to be an important medical event. An AE was considered treatment-emergent if the onset time was after administration of study drug through the Day 120 post-dose final follow-up visit or, in the event that onset time preceded study drug administration, the AE increased in severity during the 120-day post-dose follow-up period.
