Trial Outcomes & Findings for A Study to Explore the Efficacy of JNJ-67953964 in the Treatment of Depression (NCT NCT03559192)

NCT ID: NCT03559192

Last Updated: 2025-04-29

Results Overview

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), summed for a total possible score of 60. Higher scores represent a more severe condition. The MADRS evaluates apparent sadness, reported sadness, inner tension, sleep appetite, concentration, lassitude, inability to feel (interest level), pessimistic thoughts, and suicidal thoughts. Negative change from baseline indicates improvement.

Lead in Period: Placebo
Participants who successfully completed the baseline examination visit at the clinical site/unit, were treated with placebo for the entire duration of the lead-in period (up to 3 weeks).
Double-blind Treatment + Withdrawal Period: Placebo
Participants who were responders (30 percent \[%\]) or more improvement on the Montgomery-Asberg Depression Rating Scale (MADRS) total score during the placebo run-in) or non-responders to lead-in placebo group were re-randomized to receive placebo matching to JNJ-67953964 capsules (2 placebo capsules) once daily during double-blind treatment period (up to 6 weeks after lead-in period) in addition to Selective serotonin reuptake inhibitors /Serotonin and norepinephrine reuptake inhibitors (SSRI/SNRI) treatment. Participants who completed the double-blind treatment period prior to the end of Week 11 entered the withdrawal period where they were treated with placebo for 2 weeks.

Participants who were responders (30% or more improvement on the MADRS total score during the placebo run-in were responders) or non-responders to lead-in placebo group were re-randomized to receive 10 mg JNJ-67953964 capsules (2\*5 mg JNJ-67953964 capsules) once daily during double-blind treatment period (up to 6 weeks after lead-in period) in addition to SSRI/SNRI treatment.

PRIMARY outcome

Timeframe: Treatment Baseline up to Week 6 of DB-treatment period

Population: The enriched intent-to-treat (eITT) analysis set included all enrolled lead-in placebo non-responders who were randomized into a treatment period, received at least 1 dose of study medication, and had at least 1 post-baseline MADRS assessment during the treatment period. Here 'N' (number of participants analyzed) refers to the number of participants evaluable for this outcome measure.

An AE can 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 were AEs with onset during the treatment period that has worsened since baseline.

The SHAPS is a self-reported 14-item, instrument, developed for the assessment of hedonic capacity. Participants scored whether they experienced pleasure in performing a list of activities or experiences. Participants rated the answers as 1-4 where 1 indicates "Definitely agree", 2 indicates "Agree", 3 indicates "Disagree" and 4 indicates "Definitely disagree". The participant's item responses were summed to provide a total score ranging from 14 to 56. A higher total SHAPS score indicated higher levels of current anhedonia. Negative change from baseline indicated improvement.

CGI-S provides an overall clinician-determined summary measure of severity of participant's illness that considers all available information, including knowledge of participant's history, psychosocial circumstances, symptoms, behavior, and impact of symptoms on participant's ability to function. CGI-S evaluates severity of psychopathology on scale of 0 to 7. Participant is assessed on severity of mental illness at 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 most extremely ill participants. Negative change in score indicates improvement.

The SMDDS is a 16-item patient reported outcome (PRO) measure. Each item was rated by the participant according to a 5-point Likert scale. Participants respond to each question using a rating scale between 0 ("Not at all" or "Never") to 4 ("Extremely" or "Always"). Before summing the items to create a total score, item 11 ("how often did you have a poor appetite") and item 12 ("how often did you over eat") were combined into a single score by selecting the highest severity on either item. The total score was then created by summing the responses on the 15 items. The total score ranged from 0 to 60. The SMDDS uses a 7-day recall period and verbal rating scales. Higher score indicates more severe depressive symptomatology. Negative change from baseline indicates improvement.

SATE questionnaire is a 3-item self-reported scale designed to provide additional information regarding participant's subjective experience while taking treatment. This was internal Janssen questionnaire and questions were asked to participant weekly by the Q1.6-app. For rating overall depression: participant selected one option out of Improved, not changed or got worse; for depression improvement: participant selected one option out of slightly improved, much improved or very much improved; and for depression worsen: participant selected slightly worse, much worse or very much worse.

HAM-A scale assesses severity of different anxiety-related symptoms with a score range of 0 to 52. Higher score indicated severity in anxiety symptoms. Each of the 14 items is rated by clinician on a 5-point scale ranging from 0 (not present) to 4 (maximum degree). HAM-A6 is a uni-dimensional, 6-item subscale derived from HAM-A. HAM-A6 comprises of five psychic anxiety symptoms: anxious mood, psychic tension, fears, intellectual disturbances, and anxious behaviour observed at the interview, as well as one somatic item, muscular tension. HAM-A6 subscale score ranges from 0 to 24, with higher scores indicating greater severity of core symptoms.
