Study start date: September 15, 2020
Actual date on which the first participant was enrolled.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.

Criteria
8 inclusion criteria required to participate
Meet diagnostic and statistical manual of mental disorders-5th edition (DSM-5) diagnostic criteria for major depressive disorder (MDD), without psychotic features, based upon clinical assessment and confirmed by the structured clinical interview for DSM-5 Axis I disorders-clinical trials version (SCID-CT) diagnosed with first depressive episode prior to age 60. The duration of the current depressive episode must be less than or equal to (<=) 24 months
Have had an inadequate response to at least 1 but no more than 2 antidepressants, administered at an adequate dose and duration in the current episode of depression. The current antidepressant cannot be the first antidepressant treatment for the first lifetime episode of depression. An inadequate response is defined as less than (<) 50 percent (%) reduction but with some improvement (that is, improvement greater than [>] 0%) in depressive symptom severity with residual symptoms other than insomnia present, and overall good tolerability, as assessed by the MGH-ATRQ
Is receiving and tolerating well any one of the following selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI) for depressive symptoms at screening, in any formulation and available in the participating country: citalopram, duloxetine, escitalopram, fluvoxamine, fluoxetine, milnacipran, levomilnacipran, paroxetine, sertraline, venlafaxine, desvenlafaxine, vilazodone, or vortioxetine at a stable dose (at therapeutic dose level) for at least 6 weeks, and for no greater than 18 months in the current episode
Have a hamilton depression rating scale (HDRS)-17 total score greater than or equal to (>=) 20 at the first screening interview, must not demonstrate a clinically significant improvement (that is [ie], an improvement of > 20 % on their HDRS-17 total score) from the first to the second independent HDRS-17 rating, and must have a HDRS-17 total score >= 18 at the second screening interview
Show More Criteria
6 exclusion criteria prevent from participating
Has a recent (last 3 months) history of, or current signs and symptoms of, severe renal insufficiency (creatinine clearance [CrCl] < 30 milliliter per minute [mL/min]); clinically significant or unstable cardiovascular, respiratory, gastrointestinal, neurologic, hematologic, rheumatologic, immunologic or endocrine disorders and uncontrolled Type 1 or Type 2 diabetes mellitus
Has clinically significant hepatic disease as defined by >=2*Upper Limit of Normal (ULN) increase of aspartate aminotransferase (AST) or alanine aminotransferase (ALT) at screening
Has a history of treatment-resistant MDD, defined as a lack of response to 2 or more adequate antidepressant treatments in the current episode, as indicated by no or minimal (< 25% improvement in symptoms) when treated with an antidepressant of adequate dose (per massachusetts general hospital-antidepressant treatment response questionnaire [MGH-ATRQ]) and duration (at least 6 weeks).
Has history or current diagnosis of a psychotic disorder, bipolar disorder, intellectual disability, autism spectrum disorder, borderline personality disorder, or somatoform disorders
