About

This study is open to adults with depression (major depressive disorder) for whom standard treatment with antidepressants alone does not work sufficiently. The purpose of the trial is to find out whether a medicine called BI 1358894 helps to improve symptoms of depression. Four different doses of BI 1358894 are tested in the study. Participants continue their standard antidepressant therapy throughout the study. Participants are put into 6 groups by chance. Participants in 4 of the 6 groups take different doses of BI 1358894, and placebo. Participants in the fifth group take quetiapine, a medicine already used to treat depression, and placebo. Participants in the sixth group take placebo only.

Participants take BI 1358894, quetiapine, or placebo as tablets. Placebo tablets look like BI 1358894 or quetiapine tablets but do not contain any medicine. Each participant takes tablets twice a day. Participants are in the study for about 3 months. During this time, they visit the study site about 8 times and get about 2 phone calls. At the visits, doctors ask participants about their symptoms.

The results between the BI 1358894 groups, the quetiapine group, and the placebo group are then compared. The doctors also regularly check the general health of the participants.

5 mg BI 1358894

Experimental group

Description:

Participants with an established diagnosis of MDD administered one 5 milligram (mg) dose of BI 1358894 in the morning as film-coated tablet, and one dose of placebo matching quetiapine in the evening as tablets. Each administration was performed orally once daily, for 6 weeks. During the trial, participants also continued treatment with their OAD.

Drug: BI 1358894

Placebo

Placebo Comparator group

Description:

Participants with an established diagnosis of Major Depressive Disorder (MDD) administered one dose of placebo matching BI 1358894 in the morning as film-coated tablets, and one dose of placebo matching quetiapine in the evening as tablets. Each administration was performed orally once daily, for 6 weeks. During the trial, participants also continued treatment with their Ongoing Antidepressants (OAD).

Treatment:

Drug: Placebo

Quetiapine

Active Comparator group

Description:

Participants with an established diagnosis of MDD administered one dose of placebo matching BI 1358894 in the morning as film-coated tablets, and one 150 or 300 mg dose of quetiapine in the evening as tablets. Each administration was performed orally once daily, for 6 weeks. The daily active dose at the start of therapy was 50 mg on Day 1, 100 mg at Day 2 and 150 mg on Day 3 and 4. Beginning with Day 5, the recommended daily dose of 300 mg was taken. If not tolerated by a participant, the dose was reduced to 150 mg in Week 1. Thereafter, this finally chosen dose had to be stable until end of treatment at Week 6. During the trial, participants also continued treatment with their OAD.
