A Study of Seltorexant as Adjunctive Therapy to Antidepressants in Adult and Elderly Participants With Major Depressive Disorder With Insomnia Symptoms Who Have Responded Inadequately to Antidepressant and Long-term Safety Extension Treatment With Seltorexant

Janssen Research & Development, LLC588 enrolled

Overview

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 an selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI) in double-blind treatment phase and to assess the long-term safety and tolerability of seltorexant as adjunctive therapy to an antidepressant in participants with major depressive disorder (MDD) in open-label treatment phase.

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 adjunctive treatment of major depressive disorder with insomnia symptoms (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 4 phases: a screening phase (up to 30 days), a double-blind (DB) treatment phase (43 days), open label (OL) treatment phase (1-year), and a post treatment follow-up phase (7 to 14 days after end of treatment). The total study duration for each participant will be up to 64 weeks. Efficacy, safety, pharmacokinetics, and biomarkers will be assessed at specified time points during this study.

Outcomes

Primary Outcomes

Double-blind (DB) Treatment Phase: Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score

MADRS is a clinician-administered scale designed to measure depression severity and detects changes due to antidepressant treatment. The MADRS evaluates the following 10 items: apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. Each item is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total possible score of 60. Higher scores represent a more severe condition.

Time frame: Baseline, Day 43

Open-Label (OL) Treatment Phase: Number of Participants with Adverse Events (AEs) including AEs of Special Interest (AESI) as a Measure of Safety and Tolerability

Number of participants with AE including AE of special interest as a measure of safety and tolerability will be reported. An AE is any untoward medical occurrence in a clinical study participant administered a investigational or non-investigational medicinal product. An AE does not necessarily have a causal relationship with the treatment. AESI will comprise of cataplexy, sleep paralysis, complex, sleep-related behaviors/parasomnias, sleep terrors, bruxism, sleep sex, sleep related eating disorder, catathrenia, fall and motor vehicle accident.

Time frame: 1 year

OL Treatment Phase: Change From Baseline in Suicidality Assessment Using the Columbia Suicide Severity Rating Scale (C-SSRS)

Change from baseline in suicidality assessment using C-SSRS will be reported. C-SSRS is a clinician rated assessment of suicidal behavior and/or intent. Scale consists of 28 items in 4 sections: suicide behavior, actual attempts, suicidal ideation, and intensity of ideation. Suicidal ideation consists of 5 'yes/no' items: wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with any methods (not plan) without intention to act, active suicidal ideation with some intent to act without specific plan, active suicidal ideation with specific plan and intent. Only items with yes responses are listed. Worsening of suicidal ideation indicates an increase in severity of suicidal ideation from baseline. Suicidal behavior consists of 5 'yes/no' items: preparatory acts or behavior, aborted attempt, actual attempt, completed suicide.

Time frame: Baseline (Day 43), up to 1 year

OL Treatment Phase: Physician Withdrawal Checklist (PWC-20) Scores

Withdrawal symptoms assessment using the PWC-20 will be reported. The PWC-20 is a simple and accurate method used to assess potential withdrawal symptoms following cessation of treatment. The PWC-20 is a reliable and sensitive instrument for the assessment of discontinuation symptoms. Each individual item score ranges from 0 (not present) to 3 (severe), where higher scores = more affected condition.

Time frame: End of Treatment/Early withdrawal to end of the Follow-up visit (up to 14 days)

The ASEX is a patient-reported 5-item rating scale that quantifies sex drive, arousal, vaginal lubrication/penile erection, ability to reach orgasm, and satisfaction from orgasm. The total scores range from 5 to 30, with the higher scores indicating more sexual dysfunction.

Time frame: Up to 1 year

Secondary Outcomes

DB Treatment Phase: Change From Baseline in the MADRS Without Sleep Item (MADRS-WOSI) Total Score

Change from Baseline in MADRS-WOSI will be reported. MADRS-WOSI is defined as the full MADRS without the sleep item. The total score ranges from 0 to 54, with higher scores corresponding to greater symptom severity.

Time frame: Baseline and Day 43

DB Treatment Phase: Change From Baseline in Sleep Disturbance Using the Patient Reported Outcome Measurement Information System-Sleep Disturbance (PROMIS-SD) Short Form 8a T-score

The PROMIS-SD is used to assess self-reported perceptions of sleep quality, sleep depth and restoration associated with sleep. The full PROMIS-SD includes 27 items with each item based on a 7-day recall period and assessed on a 5 level Likert-type scale. The 8-item short form will be used in this study, in which responses are scored 1 to 5 for each item. A higher score on 5 of the 8 items reflects a worse outcome, whereas a higher score on 3 items reflects an improved outcome; therefore, the directionality of the 8 item scores are first synchronized prior to calculation of the total raw score. To find the total raw score for a short form with all questions answered, sum the values of the response to each question. For example, for the adult 8-item form, the lowest possible raw score is 8; the highest possible raw score is 40. Higher overall score indicates more sleep disturbance.

Time frame: Baseline and Day 43

DB Treatment Phase: Change From Baseline in the MADRS-6 Total Score

The MADRS-6 scale is a clinician-administered questionnaire used to measure the severity of MDD symptoms. The MADRS-6 scale is a subset of the MADRS-10 scale, comprises of the following individual questionnaire items: Apparent Sadness, Reported Sadness, Inner Tension, Lassitude, Inability to Feel, and Pessimistic Thoughts. Scores range from 0 (no apparent symptoms) to 36 (most severe symptoms).

Time frame: Baseline and Day 43

DB Treatment Phase: Percentage of Participants with Response on Depressive Symptoms Scale Based on Montgomery-Asberg Depression Rating Scale (MADRS)

Percentage of participants with response on depressive symptoms scale based on MADRS will be reported. Responders are defined as percentage of participants with greater than or equal to (\>=) 50 percent (%) improvement in the MADRS total score from baseline to Day 43.
