Study Endpoints

Primary Endpoints

Number of Participants With Serious Treatment-emergent Adverse Events (TEAEs)
From start of study drug administration up to 14 days after end of treatment (EOT) [up to Week 54]

An adverse event (AE) was any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product and that did not necessarily have a causal relationship with this investigational product (IP) or medicinal product. Serious AE was any untoward medical occurrence (whether considered to be related to investigational product or not) that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital abnormality/birth defect, and was an important medical event. A TEAE was defined as any event emerging at or after the initiation of treatment with an IP or any existing event that worsened in either intensity or frequency following exposure to the IP until the end of the safety follow-up period.
