Trial Outcomes & Findings for Comparison of Atomoxetine Versus Placebo in Children With Attention-Deficit/Hyperactivity Disorder (ADHD) (NCT NCT00546910)

NCT ID: NCT00546910

Last Updated: 2010-08-10

Results Overview

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.

PRIMARY outcome

Timeframe: Baseline, 8 weeks

Population: Full analysis population (N=125) including all randomized participants taking at least one dose of study medication.

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.

PRIMARY outcome

Timeframe: Baseline, 8 weeks

Population: Full analysis population (N=125) including all randomized participants taking at least one dose of study medication.

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.

Population: Full analysis population (N=125) including all randomized participants taking at least one dose of study medication.

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).

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).
