About this study
Official title: A Phase II 6-week, Randomized, Double-blinded, Placebo Controlled, Parallel Group Decentralised Clinical Trial to Evaluate Efficacy and Safety of Oral BI 1358894 in Patients With Major Depressive Disorder With Inadequate Response to Antidepressants
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in MADRS Total Score at Week 6
The Montgomery-Åsberg Depression Rating Scale (MADRS) evaluates core symptoms of depression. Nine of the items are based upon participant reports, and one is on the rater's observation (apparent sadness) during the rating interview. MADRS items are rated on a 0-6 continuum (0=no abnormality, 6=severe). Total score is calculated by the sum of the individual items, the possible total score could range from 0 to 60 (0= normal with absence of symptoms, 60=severe depression). The adjusted mean (SE) are based on a mixed effects model for repeated measures (MMRM) with fixed effects of treatment, visit, treatment by visit interaction, baseline, and baseline by visit interaction; patient as a random effect.
Measured: Week 0 (baseline) and after 1, 2, 4 and 6 week(s) of treatment. Change from baseline at week 6 MMRM estimates are reported in the table below.
Secondary outcomes (6)
Number of Subjects With ≥ 50% MADRS Reduction From Baseline at Week 6
The Montgomery-Åsberg Depression Rating Scale (MADRS) evaluates core symptoms of depression. Nine of the items are based upon participant reports, and one is on the rater's observation (apparent sadness) during the rating interview. MADRS items are rated on a 0-6 continuum (0=no abnormality, 6=severe). Total score is calculated by the sum of the individual items, the possible total score could range from 0 to 60 (0= normal with absence of symptoms, 60=severe depression). Reported are the number of subjects with ≥ 50% MADRS reduction from baseline at Weeks 6. Percent reduction from baseline was calculated as (score at baseline - score at week 6) / score at baseline * 100.
Measured: Baseline (week 0) and after 6 weeks of treatment.
Change From Baseline in State-Trait Anxiety Inventory (STAI) Scores at Week 6
The State-Trait Anxiety Inventory (STAI) comprises separate self-report scales for measuring state and trait anxiety. The S-Anxiety scale consists of twenty statements that evaluate how respondents feel "right now, at this moment." The T-Anxiety scale consists of twenty statements that assess how people generally feel. 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.
Mixed effects model for repeated measures (MMRM) with fixed effects of treatment, visit, treatment by visit interaction, baseline, and baseline by visit interaction; patient as a random effect; unstructured covariance matrix for within-patient errors and Kenward-Roger approximation for denominator degrees of freedom.
Measured: Week 0 (baseline) and after 1, 2, 4 and 6 week(s) of treatment. Change from baseline at week 6 MMRM estimates are reported in the table below.
Change From Baseline in Clinical Global Impression Severity Scale (CGI-S) Score at Week 6
The CGI-S rating scale measures the clinician's impression of the severity of illness exhibited, taking into account all available information, including knowledge of the participant's history, psychosocial circumstances, symptoms, behavior, and the impact of the symptoms on the participant's ability to function. The CGI-S evaluates the severity of psychopathology on a scale of 1 (best) to 7 (worst). 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. MMRM with fixed effects of treatment, visit, treatment by visit interaction, baseline, and baseline by visit interaction; patient as a random effect; unstructured covariance matrix for within-patient errors and Kenward-Roger approximation for denominator degrees of freedom.
Measured: Week 0 (baseline) and after 1, 2, 4 and 6 week(s) of treatment. Change from baseline at week 6 MMRM estimates are reported in the table below.
Change From Baseline in Symptoms of Major Depressive Disorder Scale (SMDDS) Total Score at Week 6
The SMDDS is a 16-item, patient-reported outcome (PRO) measure developed to capture the core symptoms of MDD. 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"). In calculating the total score, two of the items (item 11 and 12) are first combined, with the highest score across the two items selected for use in the total score calculation. Total score is then calculated by the sum of the individual 15 items, the total score ranges from 0 to 60 with a higher score indicating more severe depressive symptomatology. Mixed effects model for repeated measures (MMRM) with fixed effects of treatment, visit, treatment by visit interaction, baseline, and baseline by visit interaction; patient as a random effect; unstructured covariance matrix for within-patient errors and Kenward-Roger approximation for denominator degrees of freedom.
Measured: Week 0 (baseline) and after 1, 2, 4 and 6 week(s) of treatment. Change from baseline at week 6 MMRM estimates are reported in the table below.
Change From Baseline in Patient Global Impression Severity Scale (PGI-S) Score at Week 6
The PGI-S was used to measure the patient's impression of the severity of their illness. It is a single item 4-point scale that asks patients to rate the severity of their illness.
The PGI-S question states "Please choose the response below that best describes the overall severity of your depression symptoms over the past week."
- None
- Mild
- Moderate
- Severe
Mixed effects model for repeated measures (MMRM) with fixed effects of treatment, visit, treatment by visit interaction, baseline, and baseline by visit interaction; patient as a random effect; unstructured covariance matrix for within-patient errors and Kenward-Roger approximation for denominator degrees of freedom.
Measured: Week 0 (baseline) and after 1, 2, 4 and 6 week(s) of treatment. Change from baseline at week 6 MMRM estimates are reported in the table below.
Patient Global Impression of Change Scale (PGI-C) Score at Week 6
The PGI-C is a one-time assessment at the end of treatment (EoT) to measure the patient's impression of the how their illness has changed over time. It is a single item 7-item scale that asks patients to rate the overall change since the start of treatment.
The PGI-C question states "Please choose the response below that best describes the overall change in your depression symptoms since you started taking the study medication."

A Phase 2 study testing BI 1358894 in people with Depressive Disorder, Major, run by Boehringer Ingelheim at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 13 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 11 May 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change From Baseline in MADRS Total Score at Week 6 (time frame: Week 0 (baseline) and after 1, 2, 4 and 6 week(s) of treatment. Change from baseline at week 6 MMRM estimates are reported in the table below.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04423757, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
