Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), Discontinuations Due to AEs, and Treatment-related AEs and Who Died During Treatment PeriodBaseline (Day 1) up to 24 weeks (treatment period)

AE was defined as any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that does not has a causal relationship with treatment. SAE was defined as a medical event that at any dose resulted in death, persistent or significant disability/incapacity, or drug dependency/abuse; was life-threatening, an important medical event, or a congenital anomaly/birth defect; or required or prolonged hospitalization. Treatment-related AE was defined as an AE that had certain, probable, possible, or unknown relationship to study drug. Mild (Grade 1): awareness of event but easily tolerated; Moderate (Grade 2): discomfort enough to cause some interference with usual activity; Severe (Grade 3): inability to carry out usual activity; Very severe (Grade 4): debilitating, significantly incapacitates participant despite symptomatic therapy. Only Grade 2-4 treatment-related AEs were reported.
