Conditions
Depressive Disorder, Major
Anhedonia
Interventions
Other: Placebo
Registration Number
NCT06635135
Lead Sponsor
Janssen Research & Development, LLC
Brief Summary

The purpose of this study is to assess how well aticaprant works compared to placebo when given in addition to antidepressant therapy (selective serotonin reuptake inhibitor \[SSRI\] or serotonin-norepinephrine reuptake inhibitor \[SNRI\]) in preventing return of depression symptoms in participants with major depressive disorder who experience a loss of interest and pleasure and who achieve a stable response after treatment with adjunctive aticaprant.

Inclusion Criteria
  • Be medically stable based on physical examination (including a brief neurologic examination), medical history, vital signs (including blood pressure), and 12-lead electrocardiogram (ECG) performed at screening and OL baseline
  • Be medically stable based on clinical laboratory tests performed at screening
  • Meet DSM-5 diagnostic criteria for recurrent or single episode MDD, without psychotic features upon clinical assessment and confirmed by the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5) Axis I Disorders-Clinical Trials version (SCID-CT)
  • Have symptoms of anhedonia based on clinical assessment and confirmed by presence of anhedonia (positive response to major depressive episode (MDE) module symptom Item 2) on the SCID-CT at screening
Exclusion Criteria
  • Has had no response to 2 or more consecutive antidepressant treatments administered at adequate dose and duration in the current episode of depression including the current selective SSRI/SNRI assessed using the Massachusetts General Hospital Antidepressant Treatment Response Questionnaire (MGH ATRQ)
  • Has a history or evidence of clinically meaningful noncompliance with current antidepressant therapy
  • Has a history of moderate-to-severe substance use disorder including alcohol use disorder according to DSM-5 criteria within 6 months before screening
  • Has homicidal ideation/intent, per the investigator's clinical judgment, or has suicidal ideation with some intent to act within 3 months prior to the start of the screening phase
