Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)

时间窗: Baseline up to Week 58

Adverse event (AE) was defined as any untoward medical occurrence in a participant who received IMP and did not necessary have to had a causal relationship with treatment. All AEs that occurred from the first dose of the IMP administration up to 6 weeks after last dose of treatment (up to Week 58) were considered as TEAEs. SAEs were AEs resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly or a medically important event. TEAEs included both SAEs and non-SAEs.
