About this study
Official title: A Multicenter, Double-Blind, Randomized, Parallel-Group, Placebo-Controlled, Study to Evaluate the Efficacy and Safety of Seltorexant 20 mg as Adjunctive Therapy to Antidepressants in Adult and Elderly Patients With Major Depressive Disorder With Insomnia Symptoms Who Have Responded Inadequately to Antidepressant Therapy
The purpose of this study is to assess the efficacy of Seltorexant compared with placebo as adjunctive therapy to an antidepressant in improving depressive symptoms in participants with major depressive disorder with insomnia symptoms (MDDIS) who have had an inadequate response to current antidepressant therapy with a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI).
Read the detailed description
Major depressive disorder (MDD) is a common, serious, recurrent disorder. Seltorexant (JNJ-42847922) is a potent and selective antagonist of the human orexin-2 receptor (OX2R) that is being developed for the adjunctive treatment of MDDIS. The hypothesis for this study is that adjunctive treatment with seltorexant is superior to placebo in treating depressive symptoms, as measured by change in Montgomery Asberg Depression Rating Scale (MADRS) total score from baseline to Day 43 in adult and elderly participants with MDDIS who have had an inadequate response to treatment with a SSRI/SNRI. The study will be conducted in 3 phases: a screening phase (up to 30 days), a double-blind (DB) treatment phase (43 days), and a post treatment follow-up phase (7 to 14 days after DB treatment phase). Total duration of study is up to 12 weeks. Efficacy, safety, pharmacokinetics, and biomarkers will be assessed at specified time points during this study.

| Study group | Role | What they receive |
|---|---|---|
| Seltorexant | Experimental | Participants will receive Seltorexant orally once daily from Day 1 to Day 42 (until the end of Week 6). Receives: Drug: Seltorexant |

What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline to Day 43 in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score
The MADRS was a clinician-rated scale designed to measure depression severity and detected changes due to antidepressant treatment. The scale consisted of 10 items (apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts), each of which was scored from 0 (item not present or normal) to 6 (severe or continuous presence of symptoms). MADRS total score was the sum of scores from individual question items, which ranged from 0 to 60, higher scores represented a more severe condition. Negative change in MADRS total score indicated improvement.
Measured: Baseline (Day 1), Day 43
Secondary outcomes (5)
Change From Baseline to Day 43 in the MADRS Without Sleep Item (MADRS-WOSI) Total Score
The MADRS was a clinician-rated scale designed to measure depression severity and detected changes due to antidepressant treatment. MADRS-WOSI was defined as the full MADRS without the sleep item. The MADRS-WOSI scale consisted of 9 items (apparent sadness, reported sadness, inner tension, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts), each of which was scored from 0 (item not present or normal) to 6 (severe or continuous presence of symptoms). Higher scores represented a more severe condition. MADRS-WOSI total score was the sum of scores from individual question items, which ranged from 0 to 54, higher scores represented a more severe condition. Negative change in MADRS total score indicated improvement.
Measured: Baseline (Day 1), Day 43
Change From Baseline to Day 43 in Sleep Disturbance Using the Patient Reported Outcome Measurement Information System-Sleep Disturbance (PROMIS-SD; Short Form 8a) T-score
PROMIS-SD Short Form 8a: static 8-item questionnaire, assessed self-perceptions of sleep initiation (2 items), quality of sleep (3 items), early morning feelings (2 items), worrying about sleep (1 item). Each question has 5 options ranged 1 to 5. The "direction" of responses was not same, sometimes "not at all" =more sleep disturbance; sometimes "not at all" =less sleep disturbance. Total raw score for short form with all questions answered was sum of values of response to each question, total score ranged 8 to 40. Lower scores=less sleep disturbance. Total raw score converted into T-score. T-score rescaled the raw score into standardized score with mean-50; SD-10. Negative changes in scores=improvement. Higher PROMIS T-score represents more concept measured. Negatively worded (like sleep disturbance), T-score of 60 was one SD worse than average. By comparison, T-score of 40 was one SD better than average. T-score of 50 or above was clinically significant level of sleep disturbance.
Measured: Baseline (Day 1), Day 43
Change From Baseline to Day 43 in the 6-item MADRS (MADRS-6) Total Score
The 6-item MADRS was a clinician-administered scale designed to measure the core symptoms of depression severity and detected changes due to antidepressant intervention. It is a subset of MADRS (10-item). The MADRS-6 subscale score was the sum of scores for the following MADRS items: apparent sadness, reported sadness, inner tension, lassitude, inability to feel, and pessimistic thoughts. Each item was scored from 0 (item not present or normal) to 6 (severe or continuous presence of symptoms), the overall score ranges from 0 to 36, higher scores represented a more severe condition. Negative changes in MADRS-6 total score indicate improvement.
Measured: Baseline (Day 1), Day 43
Percentage of Participants Who Achieved Response on Depressive Symptoms Scale Based on MADRS Total Score at Day 43
Percentage of participants who achieved response on depressive symptoms scale based on MADRS total score at Day 43 were reported. Responders were defined as participants with a >=50 percent (%) improvement in the MADRS total score from baseline to a given timepoint. The MADRS was a clinician-rated scale designed to measure depression severity and detected changes due to antidepressant treatment. The scale consisted of 10 items (apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts), each of which was scored from 0 (item not present or normal) to 6 (severe or continuous presence of symptoms). MADRS total score was the sum of scores from individual question items, which ranged from 0 to 60, higher scores represented a more severe condition. Negative change in MADRS total score indicated improvement.
Measured: At Day 43
Change From Baseline to Day 43 in Patient Health Questionnaire, 9-item (PHQ-9) Total Score
The PHQ-9 was a 9-item, participant reported outcome measure to assess depressive symptoms. The scale scores each of the 9 symptom domains of the Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5) major depressive disorder (MDD) criteria. Each item was rated on a 4 point scale (0=not at all, 1=several days, 2=more than half the days, and 3=nearly every day). The participant's item responses were summed to provide a total score (range of 0 to 27), with higher scores indicating greater severity of depressive symptoms. The severity of the PHQ-9 was categorized as follows: none-minimal (0-4), mild (5-9), moderate (10-14), moderately severe (15-19) and severe (20-27). Negative changes in PHQ-9 total score indicated improvement.
Measured: Baseline (Day 1), Day 43
