Study Overview
Brief Summary
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.
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 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
OL Treatment Phase: Change From Baseline in Pulse Rate
Time Frame: Baseline (Day 43), up to 1 year
Change from baseline in pulse rate will be reported.
OL Treatment Phase: Change From Baseline in Weight
Time Frame: Baseline (Day 43), up to 1 year
Change from baseline in weight as a part of physical examination will be reported.
Double-blind (DB) Treatment Phase: Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score
Time Frame: Baseline, Day 43
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.
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
Time Frame: 1 year
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.
OL Treatment Phase: Change From Baseline in Blood Pressure
Time Frame: Baseline (Day 43), up to 1 year
Change from baseline in blood pressure will be reported.
OL Treatment Phase: Change From Baseline in Body Mass Index (BMI)
Time Frame: Baseline (Day 43), up to 1 year
Change from baseline in BMI as a part of physical examination will be reported.
OL Treatment Phase: Change from Baseline in PR Interval
Time Frame: Baseline (Day 43), up to 1 year
Change from baseline in PR interval will be measured by ECG.
OL Treatment Phase: Participant-reported Sexual Functioning Using Arizona Sexual Experiences Scale (ASEX) Score
Time Frame: Up to 1 year
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.
OL Treatment Phase: Change From Baseline in Suicidality Assessment Using the Columbia Suicide Severity Rating Scale (C-SSRS)
Time Frame: Baseline (Day 43), up to 1 year
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.
OL Treatment Phase: Number of Participants with Laboratory Abnormalities
Time Frame: Up to 1 year
Number of participants with laboratory abnormalities related to hematology, serum chemistry, coagulation, liver function tests and urinalysis will be reported.
OL Treatment Phase: Physician Withdrawal Checklist (PWC-20) Scores
Time Frame: End of Treatment/Early withdrawal to end of the Follow-up visit (up to 14 days)
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.

OL Treatment Phase: Change From Baseline in QT Interval
Time Frame: Baseline (Day 43), up to 1 year
Change from baseline in QT interval will be measured by ECG.
