Details and patient eligibility


This is a home-based study in adults with depression. People who have been diagnosed with Major Depressive Disorder can participate in the study. Participants can take part if they are being treated for their depression but still have symptoms. The purpose of this study is to find out whether a medicine called BI 1358894 helps people with depression. Participants are in the study for about 2 months and do not need to visit a study site during this time. All study visits are conducted at participant's home by a mobile study nurse, by videoconference, and by phone calls. Participants are put into 2 groups by chance. One group takes BI 1358894 tablets. The other group takes placebo tablets. Placebo tablets look like BI 1358894 tablets but do not contain any medicine. The participants answer questions about the symptoms of their depression. We then compare the results between the BI 1358894 and placebo groups. The doctors and nurses also regularly check the general health of the participants.
