Official Title
An Open-label, Long-term, Safety and Efficacy Study of Aticaprant as Adjunctive Therapy in Adult and Elderly Participants With Major Depressive Disorder (MDD)
Primary Outcomes
Outcome Description
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 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.
Outcome Measure
Number of Participants with Adverse Events (AEs)
Outcome Time Frame
Up to Week 54
Outcome Description
AEs considered to be of special interest are as Pruritus and Diarrhea.

C-SSRS is semi structured clinician-administered questionnaire designed to solicit the occurrence, severity, and frequency of suicide-related ideation and behaviors. The maximum score assigned for each participant will also be summarized into one of three categories: no suicidal ideation or behavior (0), suicidal ideation (1-5), suicidal behavior (6-10). Total score ranges from 1 to 10. Higher scores indicate greater severity.
Outcome Measure

Outcome Description
Withdrawal symptoms are assessed using the PWC-20. 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.
Outcome Measure
Withdrawal Symptoms Assessment Using the Physician Withdrawal Checklist (PWC-20)
Outcome Time Frame
Up to Week 54
Outcome Description
The ASEX is a participant-reported five-item rating scale that quantifies sex drive, arousal, vaginal lubrication/penile erection, ability to reach orgasm, and satisfaction from orgasm. Each of the 5 items is rated on a 6-point scale, ranging from 1 to 6. Total score ranges from 5 to 30, with the higher scores indicating more sexual dysfunction.

Secondary Outcomes
Outcome Description
Change from baseline in MADRS total score over time will be reported. The MADRS is a clinician-rated scale designed to measure depression severity and detects changes due to antidepressant treatment. The scale consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total score of 60. Higher scores represent a more severe condition.
Outcome Time Frame
Baseline up to Week 54
Outcome Measure
Change from Baseline in the Montgomery-asberg Depression Rating Scale (MADRS) Total Score Over Time
Outcome Description
Change from baseline in PHQ-9 total score over time will be reported. The 9-item PHQ-9 scale scores each of the 9 symptom domains of the Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5) diagnostic criteria for recurrent or single episode major depressive disorder (MDD) criteria and used both as a screening tool and a measure of response to treatment for depression. Each item is rated on a 4-point scale (0=not at all, 1=several days, 2=more than half the days, and 3=nearly every day). The participant's item responses are summed to provide a total score (range of 0 to 27), with higher scores indicating greater severity of depressive symptoms.
Outcome Time Frame
Baseline up to Week 54
Outcome Measure
Change from Baseline in the Participant Health Questionnaire, 9-Item (PHQ-9) Total Score over Time
Outcome Description
Change from baseline in DARS total score over time will be reported. The DARS is a 17-item self-report questionnaire that is designed to assess anhedonia in MDD, and particularly to increase scale generalizability while maintaining specificity. Respondents provide their own examples of rewarding experiences across the domains of hobbies, social activities, food/drink, and sensory experience. Participants answer a set of standardized questions about desire, motivation, effort and consummatory pleasure with a recall period of "right now" for the examples provided. The instrument is scored as a total sum of all items (range 0-68) with higher scores reflecting increased motivation, effort and pleasure (that is, less anhedonia).
Outcome Time Frame
Baseline up to Week 54
Outcome Measure
Change from Baseline in Dimensional Anhedonia Rating Scale (DARS) Total Score Over Time
Outcome Description
Change from baseline in the CGI-S total score over time will be reported. The CGI-S evaluates the severity of psychopathology on a scale of 0 to 7. Considering total clinical experience, a participant is assessed on severity of mental illness at the time of rating according to: 0=not assessed; 1=normal (not at all ill); 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill participants. The CGI-S permits a global evaluation of the participant's condition at a given time.
Outcome Time Frame
Baseline up to Week 54
Outcome Measure
Change from Baseline in the Clinical Global Impression-Severity (CGI-S) Total Score Over Time
Outcome Description
Percentage of participants with \>=50% reduction from baseline in the MADRS total score over time will be reported. The MADRS is a clinician-rated scale designed to measure depression severity and detects changes due to antidepressant treatment. The scale consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total score of 60. Higher scores represent a more severe condition.
Outcome Time Frame
Week 54
Outcome Measure
Percentage of Participants with Greater than or Equal to (>=) 50 percent (%) Reduction from Baseline in the MADRS Total Score Over Time
Outcome Description
Percentage of participants with remission of depressive symptoms over time, defined as a MADRS total score less than or equal to (\<=) 10 will be reported. The MADRS is a clinician-rated scale designed to measure depression severity and detects changes due to antidepressant treatment. The scale consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total score of 60. Higher scores represent a more severe condition.
