Summary

This is a study in people between 16 and 30 years of age who have a specific type of mental illness called attenuated psychosis syndrome (APS). The purpose of this study is to find out whether BI 409306 helps reduce the symptoms of APS.

Participants are in the study for 1 year and 2 months. During this time, they visit the study site about 15 times and get about 10 phone calls. Participants are put into 2 groups by chance. They get either BI 409306 or placebo. Placebo tablets look like BI 409306 tablets but do not contain any medicine. Participants take a BI 409306 or placebo tablet two times a day.

During the study, participants answer questions in interviews and complete questionnaires so the doctors can check whether the APS symptoms change. The doctors also check the general health of the participants.
