- Primary Outcome Measures
Name Time Method Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs): Week 1 to Week 4 Week 1 to Week 4 An AE was any untoward medical occurrence in a participant who received study treatment without regard to possibility of causal relationship. SAE was 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 or incapacity, congenital anomaly. A treatment emergent AE was defined as an event that emerged during the treatment period that was absent before treatment, or worsened during the treatment period relative to the pretreatment state. AEs included both serious and non-serious adverse events.
