A Study in Attention Deficit Hyperactivity Disorder in Children and Adolescents (EMD)

Assessing the Effect of Missing Doses (Off-Days) of Daily Medication in Patients Stable on Pharmacotherapy for ADHD Receiving Atomoxetine or OROS Methylphenidate: A Parallel Matched Group Clinical Study (On/Off Study)

The main purpose of the study is to help to understand the effect on children and adolescents who are stable on treatment with atomoxetine or osmotic-release oral system (OROS) methylphenidate for attention-deficit/hyperactivity disorder (ADHD) of not taking the medication for a maximum of 6 days over a 28-day study treatment period.

Study Overview

• Status: Terminated
• Conditions: Attention Deficit Hyperactivity Disorder
• Intervention / Treatment: Drug: Atomoxetine; Drug: Placebo; Drug: Osmotic-release oral system methylphenidate

Detailed Description

The present study is designed to assess the effect of missed doses of daily medication (off-days). On the off-days the patient will take a placebo (sugar pill). Over the 4 weeks of the actual study there will be 6 random off-days of study medicine and neither the caregiver, patient nor study doctor will know which days are the missing days.

To cover all aspects of the patients' lives and notably their school time, aside from investigator's assessments, evaluations will also be performed on a daily basis by those involved in their day-to-day life: parents, teachers (on school days) and the patients themselves, using an electronic diary.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Daily Parent Report of Evening and Morning Behavior-Revised (DPREMB-R) Scale Mean Total Score (On-Days Versus Off-Days) During the 4-Week Treatment Period	Parent-completed 11-item questionnaire; measures difficulty level of and 8 common evening behaviors (such as, sit through dinner) and 3 common morning behaviors (such as, get out of bed). Each item is scored on a 4-point Likert scale ranging from 0 (no difficulty) to 3 (a lot of difficulty). Total score (evening+morning) range is 0 to 33. Higher scores indicate greater difficulty in evening and morning behavior. DPREMB-R total score between days without missing doses (on-days) and days with missing doses (off-days) was not analyzed due to the insufficient sample size.	Baseline through 4 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Global Impression of Perceived Difficulties (GIPD) Scale-Patient Version Total Score and Individual Items (On-Days Versus Off-Days) During the 4-Week Treatment Period	Assesses attention-deficit/hyperactivity disorder (ADHD)-related difficulties (overall difficulties perceived in morning, during school, during homework, in evening, over entire day and night). Participant rates difficulties during past week on 7-point scale (1=normal, not difficult at all; 7=extremely difficult) for each of 5 items. Total score=sum of all subscores (items); range: 5 to 35. Higher scores=greater impairment. GIPD-Pat total score and item scores between days without missing doses (on-days) and days with missing doses (off-days) were not analyzed due to insufficient sample size.	Baseline through 4 weeks
Conners' Global Index-Teacher Rating Scale Total Score (On-Days Versus Off-Days) During the 4-Week Treatment Period	The teacher version of Conners' Global Index consists of 10 items with each item being scored on a 4-point scale ranging from 0 (not true at all, or never/seldom) to 3 (very much true, or very often/very frequent). The total score ranges from 0 to 30. Higher scores indicate greater impairment. The Conner's Global Index-Teacher Rating Scale total score between days without missing doses (on-days) and days with missing doses (off-days) was not analyzed due to the insufficient sample size.	Baseline through 4 weeks
Global Impression of Perceived Difficulties Scale-Patient Version (GIPD-Pat) Scale Total Score and Individual Items During the 4-Week Treatment Period	Assesses attention-deficit/hyperactivity disorder (ADHD)-related difficulties (overall difficulties perceived in morning, during school, during homework, in evening, over entire day and night). Difficulties during past week are rated by participant on a 7-point scale (1=normal, not difficult at all; 7=extremely difficult) for each of 5 items. Total score=sum of all subscores (items); range: 5 to 35. Higher scores=greater impairment. Mean GIPD-Pat total score and individual item scores for days with missing doses (off-days) between both groups were not analyzed due to insufficient sample size.	Baseline through 4 weeks
Attention-Deficit/Hyperactivity Disorder Rating Scale-Parent Version: Investigator Administered and Scored (ADHD-RS-IV Parent:Inv) Total Score and Subscores at Weeks 2, 3, and 4	Assesses 18 Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, Text Revision (DSM-IV-TR) ADHD diagnosis symptoms/severity in past week. Each item: 0 (none/never, rarely) to 3 (severe/very often). Total score ranges from 0 to 54. Higher total scores indicate greater illness severity. This outcome measure was not analyzed due to the insufficient sample size.	Weeks 2, 3, and 4
Clinical Global Impression-Attention Deficit/Hyperactivity Disorder-Severity Scale (CGI-ADHD-S) at Weeks 2, 3, and 4	This instrument is a single-item expert rating of the severity of the participant's attention-deficit/hyperactivity disorder (ADHD) symptoms in relation to the assessor's total experience of participants with ADHD. Severity is rated on a 7-point scale (1=normal, not ill at all; 7=among the most extremely ill participants). Higher scores represent greater illness severity. This outcome measure was not analyzed due to the insufficient sample size.	Weeks 2, 3, and 4
Emotion Expression Scale for Children (EESC)-Parent Rated Total Score up to Week 5	29-item parent-reported measure used to monitor effect of attention-deficit/hyperactivity disorder (ADHD) medication; examines 3 aspects of emotion expression: positive emotions, emotional flatness, and emotional lability. Each item rated on 5-point Likert scale (1="not at all true" to 5="very much true"). Positive emotional subscale items reversed scored (6-raw score). Total score=transformed positive emotion + emotional flatness+ emotional lability subscales. Total scores range: 29 to 145. Higher scores=emotional impairment. This outcome measure not analyzed due to insufficient sample size.	Up to Week 5
Daily Parent Report of Evening and Morning Behavior-Revised (DPREMB-R) Scale Subscores (On-Days Versus Off-Days) During the 4-Week Treatment Period	Parent-completed 11-item questionnaire; measures difficulty level of 8 common evening behaviors (such as, sit through dinner) and 3 common morning behaviors (such as, get out of bed) from 0 (no difficulty) to 3 (a lot of difficulty). Evening behavior total score range is 0 to 24. Morning behavior total score range is 0 to 9. Higher scores indicate greater difficulty in evening and morning behavior. DPREMB-R subscores between days without missing doses (on-days) and days with missing doses (off-days) not analyzed due to insufficient sample size.	Baseline through 4 weeks
Patient Outcomes Questions (On-Days Versus Off-Days) During the 4-Week Treatment Period	6-item questionnaire from attention-deficit/hyperactivity disorder (ADHD) advocacy group evaluates treatment outcomes ADHD participant's perspective. Parent completed on each day of on/off period. Each item ranged from 1 ("I totally agree") to 5 ("I totally disagree"). Items 1 and 2 pertain to sleeping and eating; high scores=better outcome. Items 3-6 pertain to behavior; high scores=worse outcome. The mean scores for analysis would have been created for each question across the days of each of the on and off phases; however, mean scores were not analyzed due to insufficient sample size.	Baseline through 4 weeks
Daily Parent Report of Evening and Morning Behavior-Revised (DPREMB-R) Scale Total Score and Subscores During the 4-Week Treatment Period	Parent-completed 11-item questionnaire; measures difficulty level of 3 common morning behaviors (such as, get out of bed) and 8 common evening behaviors (such as, sit through dinner) from 0 (no difficulty) to 3 (a lot of difficulty). Evening behavior total score range is 0 to 24. Morning behavior total score range is 0 to 9. Total score (evening+morning) range is 0 to 33. Higher scores indicate greater difficulty in evening and morning behavior. Mean DPREMB-R total score and subscores for days with missing doses (off-days) between both groups were not analyzed due to insufficient sample size.	Baseline through 4 weeks
Conners' Global Index-Teacher Rating Scale Total Score During the 4-Week Treatment Period	The teacher version of Conners' Global Index consists of 10 items with each item being scored on a 4-point scale ranging from 0 (not true at all, or never/seldom) to 3 (very much true, or very often/very frequent). The total score ranges from 0 to 30. Higher scores indicate greater impairment. The Conners' Global Index-Teacher Rating Scale total score for days with missing doses (off-days) between both groups were not analyzed due to insufficient sample size.	Baseline through 4 weeks
Global Impression of Perceived Difficulties Investigator Version (GIPD-Inv) Total Score and Subscores At Weeks 2, 3, and 4	Assesses attention-deficit/hyperactivity disorder (ADHD)-related difficulties (overall difficulties perceived in morning, during school, during homework, in evening, and over entire day and night). Difficulties during past week are rated by investigator on a 7-point scale (1=normal, not difficult at all; 7=extremely difficult) for each of 5 items. Total score=sum of all subscores (items) and ranges from 5 to 35. Higher scores indicate greater impairment. This outcome measure was not analyzed due to the insufficient sample size.
