Number of Subjects With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) | ||||||||||
End point description |
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE is an AE 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. Treatment-emergent were events between first dose of study drug to the end of study (Day 12), that were absent before treatment or that worsened relative to pre-treatment state. AEs include both serious and non-serious adverse events. Safety analysis set included all participants who received at least 1 dose of study drug.
