NameTimeMethod
Number of Participants With Treatment-emergent Adverse Events (TEAEs)Day 1 up to a maximum of 749 days

An adverse event (AE) was any untoward medical occurrence in a patient or clinical study participant administered a pharmaceutical product that does not necessarily have to have a causal relationship with this treatment. A TEAE was defined as any AE that begins on or after the date of first dose of study drug up to the date of last dose of study drug plus the number of days in the follow-up period.

Clinically significant abnormalities in physical and neurological examinations, vital signs, resting 12-lead electrocardiograms, and clinical laboratory evaluations, in addition to incidence of fall, suicidal ideation, and suicidal behavior, were reported as AEs.
