A Study in Attention Deficit Hyperactivity Disorder in Children and Adolescents

Phase 4TerminatedNCT01127646

Eli Lilly and Company23 enrolled

Overview

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.

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.

Outcomes

Primary Outcomes

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.

Time frame: Baseline through 4 weeks

Secondary Outcomes

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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.
