Summary

This study looked at the safety of a new drug called SEP-363856 for people with schizophrenia who switched from their usual antipsychotic medication. 75 participants who completed a prior study were followed for up to 25 weeks. The main goal was to track any side effects or serious health issues. This is a disease control study because schizophrenia requires ongoing management.
