Brief Summary:

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.

Primary Outcome Measures :
  1. Change from baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) total score [ Time Frame: At week 6 ]
    The MADRS consists of 10 items: apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thought, suicidal thoughts. MADRS items are rated on a 0-6 continuum (0=no abnormality, 6=severe). The possible total score could range from 0 to 60 (from normal with absence of symptoms to severe depression).

Secondary Outcome Measures :
  1. Response defined as ≥ 50% MADRS reduction from baseline [ Time Frame: At week 6 ]
  2. Change from baseline in State-Trait Anxiety Inventory (STAI) State and Trait version scores [ Time Frame: At week 6 ]
    The S-Anxiety scale (STAI Form Y-1) consists of twenty statements that evaluate how respondents feel "right now, at this moment." The T-Anxiety scale (STAI Form Y-2) consists of twenty statements that assess how people generally feel. Each STAI item is given a weighted score of 1 to 4. A rating of 4 indicates the presence of a high level of anxiety for ten S-Anxiety items and eleven T-Anxiety items (e.g., "I feel frightened," "I feel upset"). A high rating indicates the absence of anxiety for the remaining ten S-Anxiety items and nine T-Anxiety items (e.g., "I feel calm," "I feel relaxed").Scores for both the S-Anxiety and the T-Anxiety scales can vary from a minimum of 20 to a maximum of 80. Higher scores indicate greater anxiety.

  3. Change from baseline in Clinical Global Impression Severity Scale (CGI-S) score [ Time Frame: At week 6 ]
    The CGI-S evaluates the severity of psychopathology on a scale of 1 to 7. Considering total clinical experience with the depression population, a participant is assessed on severity of illness at the time of rating according to: 1=normal (not at all ill); 2=borderline ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill participants. Higher scores indicate worsening.

  4. Change from baseline in Symptoms of Major Depressive Disorder Scale (SMDDS) total score [ Time Frame: At week 6 ]
    The different categories and associated 16 items are: Negative Emotions/Mood: sadness, hopeless/helpless, irritability, anhedonia; Anxiety: feeling overwhelmed, worry; Low Energy: tiredness; Cognition: intrusive thoughts, poor concentration; Sleep Disturbances: general sleep adequacy; Self Harm/Suicide: life not worth living; Low Motivation: lack of drive, no interest in activities; Sense of Self: self-blame; Eating Behavior: poor appetite, overeating. The SMDDS uses a recall of "over the past 7 days" and participants respond to each question using a rating scale between 0 ("Not at all" or "Never") to 4 ("Extremely" or "Always"). The total score ranges from 0 to 60 with a higher score indicating more severe depressive symptomatology.
