Comparison of Atomoxetine Versus Placebo in Children With Attention-Deficit/Hyperactivity Disorder (ADHD)

Phase 4

Completed

Conditions: Attention Deficit Hyperactivity Disorder

Interventions: Drug: Placebo
Drug: Atomoxetine

Registration Number: NCT00546910

Lead Sponsor: Eli Lilly and Company

Brief Summary: This is a two-arm, parallel, randomized, double-blind, placebo-controlled Phase 4 multicenter trial to compare the whole day efficacy of atomoxetine versus placebo in children aged 6 through 12 years with Attention-Deficit/Hyperactivity Disorder (ADHD) treated in an inpatient, day-patient and outpatient setting in Germany. Core symptoms will be measured during once or bi-weekly visits, three times per visit-day, by a computer based Continuous Performance Test. Following an initial 3-28-day screening and washout phase, patients will be assigned to double-blind treatment with atomoxetine or placebo. In the verum arm, a one-week atomoxetine treatment period with the 0.5 mg/kg per day lead-in dose will be succeeded by a 7 week period at the target dose of 1.2 mg/kg per day.

Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	Placebo matched to 1 week lead-in and 7 week standard target dose of atomoxetine
Atomoxetine	Atomoxetine	0.5 milligram per kilogram (mg/kg) per day lead-in dose for 1 weeks followed by 7 weeks at 1.2 mg/kg per day dose.

Primary Outcome Measures

Name	Time	Method
Change From Baseline Computer-based Continuous Performance Test (cb- CPT; Qbtech AB, Sweden), Variable: Hyperactivity (Includes Time Active [TA], Distance [DIS], Area [AR], Microevents [ME], Motion Simplicity [MS]) Q-scores At Week 8	Baseline, 8 weeks (W8)	Infra-red camera tracks movement of head reflector on patient performing computer test. Hyperactivity test variables: TA=percent time patient moved\>1 centimeter (cm)/second; DIS=path of movement (m); AR=total area (cm2) of movements; ME=number of position changes\>1 mm; MS=degree (percent) of directional changes. Results are converted to Q-scores (age and sex-adjusted normalized scores with a mean=0 and standard deviation (SD)=1 in general population, expressing the probability determined by the Gamma function in terms of SD of Gaussian density). Higher scores reflect more severe symptoms.
Change From Baseline cb CPT Variable: Impulsivity (Includes Commission Error [CE], Anticipatory Response [AR]) Q-scores At Week 8	Baseline, 8 weeks	Computer test. Patient is to press button if target appears, but not at non-target. Impulsivity variables during test: CE=percent of response to non-target; ANT=percent of responses prior to target presentation. Results are converted to Q-scores (age and sex-adjusted normalized scores with a mean=0 and standard deviation=1 in the general population, expressing the probability determined by the Gamma function in terms of standard deviation of Gaussian density). Higher scores reflect more severe symptoms.
Change From Baseline cb CPT Variable: Inattention (Includes Reaction Time Variation[RTV], Omission Error [OR], Mean Reaction Time [mRT], Normalized Variation Of Reaction Time [nVRT]) Q-scores At Week 8	Baseline, 8 weeks	Computer test. Patient is to press button if target appears, but not at non-target. Inattention test variables: mRT=average time (ms) from target presentation to response; RTV=standard deviation of mRT; nVRT=RTV expressed in terms of RT (variation as a percent of mean value); OE= percent of omitted targets. Results are converted to Q-scores (age and sex-adjusted normalized scores with a mean=0 and SD=1 in the general population, expressing the probability determined by the Gamma function in terms of SD of Gaussian density). Higher scores reflect more severe symptoms.
Change From Baseline cb CPT Variable: Other (Includes Error Rate [ER] and Multi Response [MR]) Q-scores At Week 8	Baseline, 8 weeks	Computer test. Patient is to press button if target appears, but not at non-target. Other variables during test: ER=percent of overall incorrect responses (CE and OE); MR=percent of multiple responses per presentation of target (patient responds more than once to target). Results are converted to Q-scores (age and sex-adjusted normalized scores with a mean=0 and standard deviation=1 in the general population, expressing the probability determined by the Gamma function in terms of standard deviation of Gaussian density). Higher scores reflect more severe symptoms.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline Attention-Deficit/Hyperactivity Disorder Rating Scale-IV-Parent Version: Investigator-Administered And Scored (ADHDRS-IV-Parent:Inv) Total Score At Week 8	Baseline, 8 weeks	Measures the 18 symptoms contained in the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, Text Revision (DSM-IV-TR) diagnosis of Attention-Deficit/Hyperactivity Disorder. Individual item scores range from 0 (none/never or rarely) to 3 (severe/very often). Total scores range from 0 to 54.
Change From Baseline Clinical Global Impressions-Severity of ADHD (CGI-S-ADHD) Score at Week 8	Baseline, 8 weeks	CGI-S-ADHD measures severity of the patient's overall severity of ADHD symptoms (1=normal, not at all ill; 7=among the most extremely ill patients).
Change From Baseline Weekly Rating Of Evening and Morning Behavior-Revised-Investigator Rated, Total and Subscores at Week 8	Baseline, 8 weeks	Weekly Rating Of Evening \& Morning Behavior-Revised-Investigator Rated (WREMB-R-Inv) measures the level of difficulty of 11 common morning or evening behaviors (e.g. getting out of bed, doing homework, sitting through dinner). Possible scores for each item range from 0 (no difficulty) to 3 (a lot of difficulty) with a Total score (maximum score=33), Morning subscore (maximum score=9), Evening subscore (maximum score=24), and Item 11 score which pertains to degree of difficulty falling asleep (maximum score=3).
