Main objective of the trial

The main objectives of this trial are to provide proof of concept (PoC) and dose-ranging data of BI 1358894 compared to placebo in patients with MDD to support dose selection for pivotal studies.

Protection of trial subjects

Only subjects that met all the inclusion and none of the exclusion criteria were to be entered into the study. All subjects were free to withdraw from the clinical trial at any time for any reason given. Close monitoring of all subjects was adhered to throughout the trial conduct.

Recruitment details

This was a Phase II, 6-week parallel-group multicenter, randomized, double blind, doubledummy, placebo-controlled trial with a Quetiapine arm in participants with MDD with inadequate response to ongoing treatment with a Selective Serotonin Reuptake Inhibitor or a Serotonin Norepinephrine Reuptake Inhibitor or bupropion.

Screening details

All patients were screened for eligibility prior to participation in the trial, to ensure that they met all inclusion and none of the exclusion criteria. One subject was randomized to the placebo arm but treated with 125 mg BI 1358894. One subject was randomized to the Quetiapine arm, but not treated.

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.

Montgomery-Åsberg Depression Rating Scale (MADRS) total score
The MADRS evaluates core symptoms of depression and consists of 10 items. Nine of them 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). The possible total score could range from 0 (normal with absence of symptoms) to 60 (severe depression). Baseline MADRS total score is the last non-missing value recorded prior to first dose of trial medication. Treated Set (TS).

End point title

Change from baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) total score at Week 6 ^[1]

End point description

Change from baseline in MADRS total score at Week 6 is reported. Adjusted mean and standard error (SE) were estimated by Restricted Maximum Likelihood (REML)−based Mixed effects model for repeated measures (MMRM) including the fixed categorical effects of treatment, concomitant psychotherapy use (yes vs. no), and the fixed continuous effect of baseline MADRS total score. Visit was treated as a repeated measure with an unstructured covariance matrix. The Kenward-Roger approximation was used to estimate the denominator degrees of freedom and adjust standard errors. Full analysis set (FAS): all participants in TS that have a baseline and at least one evaluable post-baseline measurement. Quetiapine arm is not included in any of the analyses using a statistical model and is therefore not reported here.

End point type

Primary

End point timeframe

MMRM included measurements from baseline (Week 0) and at Weeks 1, 2, 4 and 6 after first drug administration. MMRM estimates of change from baseline to Week 6 is reported.

Notes
[1] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
Justification: As per protocol, the endpoint applies only to placebo and BI-treated arms

End point description

Number of participants with response defined as ≥ 50% MADRS reduction from baseline at Week 6 is reported. Percent reduction from baseline was calculated as follows: [(MADRS total score at baseline - MADRS total score at week 6)/ MADRS total score at baseline] *100. Full analysis set (FAS): all participants in TS that have a baseline and at least one evaluable post-baseline measurement. Quetiapine arm is not included in any of the analyses using a statistical model and is therefore not reported here.

Change from baseline in State-Trait Anxiety Inventory (STAI) State and Trait version scores at Week 6 ^[16]

End point description

Change from baseline in STAI State and Trait version scores at Week 6 is reported. The STAI comprises separate self-report scales consisting of 20 statements for measuring state and trait anxiety. The S-Anxiety scale evaluates how respondents feel “right now, at this moment.” The T-Anxiety scale assesses how people generally feel. Each STAI item is given a score of 1 to 4. Scores for both scales can vary from 20 to 80. Higher scores indicate greater anxiety. Adjusted mean and SE were estimated by REML−based MMRM including the fixed categorical effects of treatment, concomitant psychotherapy use (yes vs. no), and the fixed continuous effect of baseline score. Visit was treated as a repeated measure with an unstructured covariance matrix. The Kenward-Roger approximation was used to estimate the denominator degrees of freedom and adjust standard errors. FAS. Quetiapine arm is not included in any of the analyses using a statistical model and is therefore not reported here.

Secondary

End point timeframe

MMRM included measurements from baseline (Week 0) and at Weeks 1, 2, 4 and 6 after first drug administration. MMRM estimates of change from baseline to Week 6 is reported.

Notes
[16] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
Justification: As per protocol, the endpoint applies only to placebo and BI-treated arms.

Change from baseline in Clinical Global Impression Severity Scale (CGI-S) score at Week 6 ^[25]

End point description

Change from baseline in CGI-S score at Week 6 is reported. The CGI-S rating scale 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. Adjusted mean and SE were estimated by REML−based MMRM including the fixed categorical effects of treatment, concomitant psychotherapy use (yes vs. no), and the fixed continuous effect of the baseline score. Visit was treated as a repeated measure with an unstructured covariance matrix. The Kenward-Roger approximation was used to estimate the denominator degrees of freedom and adjust standard errors.

Change from baseline in Symptoms of Major Depressive Disorder Scale (SMDDS) total score at Week 6 ^[30]

End point description

Change from baseline in SMDDS total score at Week 6 is reported. The SMDDS is a 16-item, patient-reported outcome 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"). The total score ranges from 0 to 60 with a higher score indicating more severe depressive symptomatology. Adjusted mean and SE were estimated by REML−based MMRM including the fixed categorical effects of treatment, concomitant psychotherapy use (yes vs. no), and the fixed continuous effect of the baseline score. Visit was treated as a repeated measure with an unstructured covariance matrix. The Kenward-Roger approximation was used to estimate the denominator degrees of freedom and adjust standard errors.
