April 24, 2025 updated by: Janssen Research & Development, LLC

A Multicenter, Randomized, Placebo-Controlled, Double-Blind Study to Investigate the Safety, Tolerability, and Clinical Efficacy of Seltorexant (JNJ-42847922) on Behavioral and Psychological Symptoms of Dementia in Patients With Probable Alzheimer's Disease

The purpose of this study is to investigate the effect of seltorexant versus placebo on the sum of Agitation and Aggression domain scores (A plus A) of the Neuropsychiatric Inventory-Clinician rating (NPI-C) in participants with probable Alzheimer's Disease (AD) with clinically significant agitation/aggression.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

55 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Neuropsychiatric Inventory Clinician Version (NPI-C) Sum of Agitation and Aggression Domain Scores (NPI-C A+A) at Day 43: Analyzed Under Estimand 1
Time Frame: Baseline (Day 1) and Day 43
The NPI-12, measure of psychobehavioral disturbances assessed frequency and severity of disturbances in 12 domains, based on a caregiver interview. Frequency for each domain was rated on a 4-point scale (from 1=rarely to 4=very often) and severity on a 3-point scale (from 1=mild to 3=severe), with the score for each domain being product of frequency and severity scores, such that each domain was scored from 1 to 12. The NPI-12 total score was the sum of 12 domain scores, ranging from 0 (best) to 144 (worst), higher score represented greater frequency and worst severity of the symptoms. NPI-C was an instrument developed on basis of original NPI that gives a score based on product of frequency and severity ratings of 12 symptom domains that were summed to a total score. NPI-C domains: agitation and aggression NPI-C A+A were scored based on both caregiver and participant interviews and score ranged from 0 (does not occur) to 63 (severe). Higher scores indicated more severity.
Baseline (Day 1) and Day 43
Change From Baseline in NPI-C A+A at Day 43: Analyzed Under Estimand 2
Time Frame: Baseline (Day 1) and Day 43
The NPI-12, measure of psychobehavioral disturbances assessed frequency and severity of disturbances in 12 domains, based on a caregiver interview. Frequency for each domain was rated on a 4-point scale (from 1=rarely to 4=very often) and severity on a 3-point scale (from 1=mild to 3=severe), with the score for each domain being product of frequency and severity scores, such that each domain was scored from 1 to 12. The NPI-12 total score was the sum of 12 domain scores, ranging from 0 (best) to 144 (worst), higher score represented greater frequency and worst severity of the symptoms. NPI-C was an instrument developed on the basis of original NPI that gives a score based on product of frequency and severity ratings of 12 symptom domains that were summed to a total score. NPI-C domains: agitation and aggression NPI-C A+A were scored based on both caregiver and participant interviews and score ranged from 0 (does not occur) to 63 (severe). Higher scores indicated more severity.
Baseline (Day 1) and Day 43

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Cohen-Mansfield Agitation Inventory- Community Version (CMAI-C) Total Score at Day 43
Time Frame: Baseline (Day 1) and Day 43
The CMAI-C, 37-item scale, measured the ability of a drug to reduce overall frequency of agitation symptoms, including aggressive behaviors. Individual items were rated by the clinician on a scale of 1 (never) to 7 (several times per hour) in which higher score represented the most frequent for each item assessed. CMAI-C total score was a sum of all categories that ranged from 37 (never) to 259 (several times), where higher score indicated greater severity.
Baseline (Day 1) and Day 43
Change From Baseline in Sleep Disorder Inventory (SDI) Average Total Score at Day 43
Time Frame: Baseline and Day 43
SDI: based on caregiver (CG) interview and expanded version of item 11 (night-time behavioral disturbances) of NPI-12. It described frequency, severity and CG burden of sleep-disturbed behaviors for period prior to its administration. It consisted of 7 sub-questions from NPI-12 sleep disturbance item. Each sub-question was made into separate questions with frequency, severity, and CG distress rated with respect to participant. SDI score derived after CG rated frequency, severity of each of 7 separate sleep disturbance symptoms. CG distress ratings were not part of SDI total score, but distress was measured. Frequency scored on scale of 0 (not present) to 4 (once or more per day), severity scored on scale of 0 (not present) to 3 (occurrence of nighttime behaviors) and CG distress rated on scale of 0 (not at all) to 5 (extremely). SDI average total score=average frequency of item 1 to 7 multiplied with average severity of items 1 to 7; ranged from 0 to 12; higher score=greater severity.
Baseline and Day 43
Observed Plasma Concentrations of Seltorexant and Its Metabolite (M12)
Time Frame: Either Day 15 (8 and 14 hours post dose on night of Day 14) or Day 43 (8 and 14 hours post dose on night of Day 42)
The pharmacokinetic (PK) sample collection was done based on the availability of the participants either on Day 15 or 43 and thus collected data were analyzed and summary data were reported in this outcome measure. Plasma samples were analyzed using liquid chromatography/mass spectrometry/mass spectrometry (LC-MS/MS) method.
Either Day 15 (8 and 14 hours post dose on night of Day 14) or Day 43 (8 and 14 hours post dose on night of Day 42)
