Clinical Trial Summary

This study will evaluate atomoxetine's efficacy in treating attention-deficit/hyperactivity disorder (ADHD) symptoms and atomoxetine's effect on functional outcomes in young adults.

A gatekeeper strategy will be employed for sequentially testing the secondary objectives.

This study also has an observational community sample arm in which patients will complete all the efficacy measurements via web-based self reporting.

Secondary	Mean Change From Baseline to 12-Week Endpoint on the Epworth Sleepiness Scale (ESS)	Used to determine the level of daytime sleepiness. The ESS is a self-rated questionnaire with 8 items that describe normative daily situations known to vary in their soporific qualities. Subjects rate the likelihood of dozing off or falling asleep in each of these situations. Each item is rated on a 4-point scale from 0 (would never doze) to 3 (high chance of dozing). The item scores are summed to produce a total score (range of 0-24). Score >10 (95th percentile) are considered to be suggestive of significant daytime sleepiness.	Baseline, 12 weeks	No
Secondary	Responders by Baseline Smoking Status	Baseline smoking status was recorded and associations to response to treatment were determined. Response was defined as 25% or greater decrease in ADHD symptoms as measured by the CAARS-Inv:SV total ADHD symptom score. The 18-item total CAARS-Inv:SV ADHD symptom score is the sum of the Inattention and Hyperactivity-Impulsivity subscales. Each item is scored on a 0 to 3 scale (0=not at all, never; 1=just a little, once in a while; 2=pretty much, often; 3=very much, very frequently). The scale assesses symptom severity over the past week. The total score ranges from 0 to 54.	12 weeks	No
Secondary	Strong Responders by Baseline Smoking Status	Baseline smoking status was recorded and associations to response to treatment were determined. Strong response was defined as 40% or greater decrease in ADHD symptoms as measured by the CAARS-Inv:SV total ADHD symptom score. The 18-item total CAARS-Inv:SV ADHD symptom score is the sum of the Inattention and Hyperactivity-Impulsivity subscales. Each item is scored on a 0 to 3 scale (0=not at all, never; 1=just a little, once in a while; 2=pretty much, often; 3=very much, very frequently). The scale assesses symptom severity over the past week. The total score ranges from 0 to 54.	12 weeks	No
