Drug: Aticaprant
Other: Placebo
Registration Number
NCT05550532
Lead Sponsor
Janssen Research & Development, LLC
Brief Summary

The purpose of this study is to evaluate the efficacy of aticaprant compared with placebo as adjunctive therapy to an antidepressant in improving depressive symptoms in adult participants with major depressive disorder (MDD) with moderate to severe anhedonia (ANH+) who have had an inadequate response to current antidepressant therapy with a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI).

Detailed Description

Depression is a common and serious psychiatric disorder which is a leading cause of disability worldwide and is associated with elevated mortality and suicide risk. Aticaprant (JNJ-67953964) is a once daily, highly selective kappa opioid receptor (KOR) antagonist, with demonstrated selectivity over mu opioid receptor (MOR) and delta opioid receptor (DOR) being developed for adjunctive treatment of MDD with ANH+. The total duration of the study will be up to 87 days. Safety evaluation including adverse events, physical examinations, urine drug test, alcohol breath tests and clinical laboratory tests will be assessed at specific time points during this study.

Primary Outcome Measures
NameTimeMethod
Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score to Day 43Baseline to Day 43

Change from baseline in MADRS total score to Day 43 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 possible score of 60. Higher scores represent a more severe condition.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline in MADRS Total Score over TimeBaseline up to Day 57

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 possible score of 60. Higher scores represent a more severe condition.

Change From Baseline in Dimensional Anhedonia Rating Scale (DARS) Total Score to Day 43Baseline to Day 43

Change from baseline in DARS total score to Day 43 will be reported. DARS is a 17-item self-report questionnaire that is designed to assess anhedonia in major depressive disorder (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 on 0 (not at all) to 4 (very much) and the total score is calculated as a sum of all items (range 0-68) with higher scores reflecting increased motivation, effort and pleasure (that is, less anhedonia).

Percentage of Responders on Depressive Symptoms Scale from Baseline to Day 43 as Assessed by MADRS Total ScoreBaseline to Day 43

Percentage of responders on depressive symptoms scale, defined as a greater than or equal to (\>=) 50 percent (%) improvement in MADRS total score from baseline to Day 43 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 possible score of 60. Higher scores represent a more severe condition.

Change From Baseline in Patient Health Questionnaire, 9-item (PHQ-9) Total Score to Day 43Baseline to Day 43

Change from baseline in PHQ-9 total score to Day 43 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) MDD criteria and it is 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.

Change From Baseline in DARS Total Score Over TimeBaseline up to Day 57

Change from baseline in DARS total score over time will be reported. DARS is a 17-item self-report questionnaire that was 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 on 0 (not at all) to 4 (very much) and the total score is calculated as a sum of all items (range 0-68) with higher scores reflecting increased motivation, effort and pleasure (that is, less anhedonia).

Change from Baseline in the PHQ-9 Anhedonia-specific Item (PHQ-9, Item 1) Over TimeBaseline up to Day 57

Change from baseline in the PHQ-9 Anhedonia-specific item (PHQ-9, Item 1) over time will be reported. The 9-item PHQ-9 scale scores each of the 9 symptom domains of the DSM-5 MDD criteria and it is 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.

Percentage of Participants With a Score Less than (<) 2 in the PHQ-9 Anhedonia-specific Item (PHQ-9, Item 1) at Day 43Day 43

Percentage of participants with a score \< 2 in the PHQ-9 Anhedonia-specific Item (PHQ-9, Item 1) at Day 43 will be reported. The 9-item PHQ-9 scale scores each of the 9 symptom domains of the DSM-5 MDD criteria and it is 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.

Change From Baseline Over Time in the Patient-Reported Outcomes Measurement Information System (PROMIS) Short Form - Ability to Participate in Social Roles and Activities 8a (PROMIS-APS 8a)Baseline up to Day 57

The PROMIS-APS 8a includes items selected from the PROMIS item bank to provide an assessment of the current degree of involvement in one's usual social roles, activities, and responsibilities, including work, family, friends, and leisure. The 8-item short form will be used in this study, and responses to every item are in a 5-point ordinal scale ranging from 1 = "Always" to 5 = "Never," with higher scores indicating better social functioning. The total scores of PROMIS-APS 8a are scaled on a T-score metric with a mean of 50 and a standard deviation (SD) of 10.

Percentage of Participants With Remission of Depressive Symptoms at Day 43 as Assessed by MADRS Total ScoreDay 43

Percentage of participants with remission of depressive symptoms, defined as a MADRS total score of less than or equal to (\<=) 10 at Day 43 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 possible score of 60. Higher scores represent a more severe condition.
