A Study of Esketamine Nasal Spray Versus Placebo Spray in Adult Participants With Treatment-resistant Depression
July 15, 2026 updated by: Janssen Research & Development, LLC
A Randomized, Double-blind, Multicenter, Placebo-controlled Study to Evaluate the Efficacy, Safety, and Tolerability of Esketamine Nasal Spray, Administered as Monotherapy, in Adult Participants With Treatment-resistant Depression
The purpose of this study is to evaluate how well each individual dose of esketamine (56 milligrams [mg] and 84 mg) works when compared with placebo in improving depressive symptoms in participants with treatment resistant depression (individuals with major depressive disorder [MDD] who have not responded to at least 2 different antidepressant treatments given at an adequate dose for an adequate duration in the current episode of depression).

DB Treatment Phase: Change From Baseline in Anhedonia Symptoms Over Time to the End of the 4-Week DB Treatment Phase As Assessed by MADRS Anhedonia Factor Score
Time Frame: Baseline up to end of the 4-Week DB treatment phase (Day 28)
|
Change from baseline in anhedonia symptoms over time to the end of the 4-week DB treatment phase as assessed by MADRS anhedonia factor score will be reported.
The MADRS anhedonia factor is a widely used 5-item subscale of the MADRS used to specifically measure the lack of pleasure (anhedonia) in depression, combining items for apparent sadness, reported sadness, concentration difficulties, lassitude (tiredness), and inability to feel.
The sum of these five items (each scored 0-6), resulting in a score from 0 to 30, with higher scores indicating more severe anhedonia.
This score helps assess treatment effectiveness for anhedonia, correlates with functional improvement, and provides a deeper look beyond the total depression score, showing significant clinical relevance in major depressive disorder (MDD) trials.

An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non-investigational) product.
An AE does not necessarily have a causal relationship with the intervention.
An AE can therefore be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non-investigational) product, whether or not related to that medicinal (investigational or non-investigational) product.
TEAEs are defined as any adverse event occurring at or after the administration of study intervention.
