Brief Summary
LYDO is a multi-center study that will enroll approximately 1925 adult outpatients with Attention Deficit/Hyperactivity Disorder (ADHD). Patients will receive, under open label conditions, atomoxetine up to 100 mg/day during the acute, open-label part of the study. Those patients that meet the response criteria will continue the blind phase of the study up to a year. During that period, patients that respond to atomoxetine will be randomized to continue the treatment with atomoxetine or with placebo (neither the patients nor investigators know if patients receive atomoxetine or placebo).

Outcome Measures
Primary Outcomes (1)
Percentage of Participants Who Maintain a Satisfactory Response During the Double-Blind Maintenance/Randomized Withdrawal Period
Conners' Adult ADHD Rating Scale-Investigator Rated:Screening Version (CAARS-Inv:SV); 30-item scale (3 subscales): inattention, hyperactivity/impulsivity (9 items each), ADHD Index (12 items). Each item is scored 0 (not at all/never) to 3 (very much/very frequently). Total ADHD symptoms score (SS)=inattention+hyperactivity/impulsivity (range:0-54). Higher score=more impairment. Clinical Global Impressions-ADHD-Severity (CGI-ADHD-S) measures participant's overall severity of ADHD symptoms and scores range from 1 (normal, not at all ill) to 7 (among the most extremely ill participants). Maintenance of response during the randomized withdrawal phase was a reduction of ≥30% in the baseline CAARS-Inv:SV Total ADHD SS and a CGI-ADHD-S score ≤3. Participants had to continuously meet the response criteria, except for 1 excursion after assessment at Week 24 through Week 37 and 1 other excursion after assessment at Week 37 through Week 49. Excursions were not permitted at 2 consecutive visits.
