An Efficacy and Safety Study for JNS001 in Adults With Attention-Deficit Hyperactivity Disorder

June 27, 2013 updated by: Janssen Pharmaceutical K.K.

A Double-blind, Placebo-controlled, Parallel-Group Study to Evaluate the Efficacy and Safety of JNS001 in Adults With Attention-Deficit/Hyperactivity Disorder at Doses of 18 mg, 36 mg, 54 mg, or 72 mg Per Day

The main purpose of this study is to evaluate the efficacy of JNS001 titrated to daily doses of 18 to 72 mg in adults with attention-deficit hyperactivity disorder (ADHD) relative to placebo.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a randomized (the study drug is assigned by chance), double-blind (DB, neither physician nor patient knows the name of the assigned drug), multicenter, placebo-controlled, parallel group (each group of patients will be treated at the same time), dose-titration study. This study consists of a screening period, a DB phase (titration period and efficacy assessment period), and post-study phase. The study includes a 1 to 2-week screening period for wash-out of prohibited drugs, and screening for eligibility. Eligible patients will be randomly assigned to receive JNS001 or placebo in a ratio of 1:1. The study also includes a 4-week titration period. Patients will be titrated from a starting dose of 18 mg/day or matching placebo for 7 days (+/- 2 days), and continue with a weekly (+/- 2 days) increment of 18 mg until an individualized dose is achieved. Once an individualized dose is achieved, patients will remain on that dose for the rest of the titration period as far as tolerable. Doses can be tapered down only once during the titration period in the study, and their dose cannot be up-titrated again for the rest of the period. The 4-week titration period will be followed by the 4-week efficacy assessment period. The post-study phase for collection of additional safety data will be scheduled for 1 week after a patient's final study treatment. The study drug will be administered with water once daily in the morning at doses of 18 mg, 36 mg, 54 mg, 72 mg per day or the matching placebo. The study treatment period is 8 weeks (titration period of 4 weeks and efficacy assessment period of 4 weeks).

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

18 years to 64 years (ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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 to Endpoint in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) Total Attention Deficit-Hyperactivity Disorder (ADHD) Symptoms Scores of Conners' Adult ADHD Rating Scale - Observer Screening Version (CAARS-O: SV)
Time Frame: Baseline (Day 0) to Endpoint (Week 8)
CAARS-O: SV evaluates DSM-IV-oriented inattention, impulsivity and hyperactivity as well as measures of self-concept. The CAARS-O:SV comprises 30 items to measure symptoms for ADHD in adults. Each item is scored from 0 (not at all, never) to 3 (very much, very frequently) with higher scores corresponding to worse symptoms. The total score can range from 0 (best) to 90 (worst). Lower score indicates improvement in ADHD symptoms.
Baseline (Day 0) to Endpoint (Week 8)

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
Mean Change From Baseline to Endpoint in the Conners' Adult ADHD Rating Scale - Observer Screening Version (CAARS-O: SV) Total Score Other Than Total Attention Deficit-Hyperactivity Disorder (ADHD) Symptoms Score
Time Frame: Baseline (Day 0) to Endpoint (Week 8)
CAARS-O: SV evaluates DSM-IV-oriented inattention, impulsivity and hyperactivity as well as measures of self-concept. The CAARS-O: SV comprises 30 items to measure symptoms for ADHD in adults. Each item is scored from 0 (not at all, never) to 3 (very much, very frequently) with higher scores corresponding to worse symptoms. The total score can range from 0 (best) to 90 (worst). Lower score indicates improvement in ADHD symptoms.
Baseline (Day 0) to Endpoint (Week 8)
Change From Baseline to Endpoint in Clinical Global Impression - Severity (CGI-S) Scores
Time Frame: Baseline (Day 0) to Endpoint (Week 8)
The CGI-S rating scale is used to rate the severity of a patient's psychotic condition on a 7-point scale. It is rated as follows: 1=Normal, not at all ill, 2=Borderline mentally ill, 3=Mildly ill, 4=Moderately ill, 5=Markedly ill, 6=Severely ill, and 7=Among the most extremely ill. Higher scores indicate worsening.
Baseline (Day 0) to Endpoint (Week 8)
Clinical Global Impression of Change (CGI-C) Scores
Time Frame: Endpoint (Week 8)
The CGI-C is a assessment of change in global clinical status, defined as a sense of well-being and ability to function in daily activities. CGI-C scores range from 1 (very much improved) through to 7 (very much worse). Higher scores indicate worsening.
Endpoint (Week 8)
Mean Change From Baseline to Endpoint in the Conners' Adult Attention Deficit-Hyperactivity Disorder (ADHD) Rating Scales-Self Report: Screening Version (CAARS-S:SV) Score
Time Frame: Baseline (Day 0) to Endpoint (Week 8)
CAARS-S:SV evaluates DSM-IV-oriented inattention, impulsivity and hyperactivity as well as measures of self-concept. The CAARS-S:SV comprises 30 items to measure symptoms for ADHD in adults. Each item is scored from 0 (not at all, never) to 3 (very much, very frequently) with higher scores corresponding to worse symptoms. The total score can range from 0 (best) to 90 (worst). Lower score indicates improvement in ADHD symptoms.
Baseline (Day 0) to Endpoint (Week 8)
Mean Change From Baseline to Endpoint in Quality of Life Enjoyment and Satisfaction Questionnaire - Short Form (Q-LES-Q-SF) Total Scores
Time Frame: Baseline (Day 0) to Endpoint (Week 8)
Q-LES-Q-SF is a 16-item questionnaire in which each question is rated on a 5-point scale with scores ranging from "1 = very poor" to "5 = very good". The total raw score is calculated by summing up the scores for the 16 items. The raw total score is transformed into a percentage maximum possible score using the following formula:(raw total score -minimum score) / (maximum possible raw score -minimum score). The minimum raw score on the Q-LES-Q-SF is 16 (worst), and the maximum score is 80 (best). A higher score indicates a better quality of life.
