Study Endpoints

Primary Endpoints

Percentage of Participants with Adverse Events
Up to approximately 40 weeks
Change From Baseline in Columbia-Suicide Severity Rating Scale (C-SSRS) Scores
Up to approximately 40 weeks

C-SSRS measures 4 constructs as follows: severity of ideation, intensity of ideation, behavior, and lethality of actual suicide attempts. Binary (yes/no) data are collected for 10 categories. Numeric ratings are provided for intensity of ideation (if present), from 1 to 5, with 1 being the least severe and 5 being the most severe.
