Study Endpoints

Primary Endpoints

Incidence and severity of Adverse Events (AEs) and Serious Adverse Events (SAEs)
at month 36

Month 36 is assumed to be study end. Incidence and severity of AEs and SAEs by treatment group, including changes in vital signs, electrocardiograms (ECGs) and laboratory results qualifying and reported as AEs.
