Clinical Trial Summary

This is a parallel design, double-blind, placebo-controlled, multi-center, 38-week treatment trial of atomoxetine in adults with attention deficit hyperactivity disorder (ADHD) who are currently living in a family situation with at least one child. The primary objective of the study is to demonstrate the efficacy of atomoxetine compared to placebo in the reduction of ADHD symptoms over 12 and 24 weeks of blinded treatment.

Description:

The initial study was 34 weeks long; however, the protocol was amended to extend the open-label period of the study from 8 weeks to 12 weeks (38 weeks total).

Separate scales measure state (20 items) and trait (20 items) anxiety. The participant reports how they feel "right now at this moment" for state anxiety and how they "generally" feel for trait anxiety. The "state" items are scored as: 1 (not at all), 2 (somewhat true), 3 (moderately true), 4 (very true). The "trait" items are scored as: 1 (almost never), 2 (sometimes), 3 (often), 4 (almost always). Scores range from 4-80 for each scale. Higher scores indicate more impaired participants.	Baseline, 12 weeks, 24 weeks	No
Secondary	Change From Baseline to 1 Week of Titration in the CAARS-Inv:SV Total Attention Deficit Hyperactivity Disorder (ADHD) Symptoms and Subscale Scores	30-item scale containing 3 subscales: inattention (9 items), hyperactivity/ impulsivity (9 items), and ADHD Index (12 items). Each item is scored 0-3 (0=not at all/never; 1=just a little/once in a while; 2=pretty much/often; 3=very much/very frequently). Total ADHD symptoms score=sum of the inattention and hyperactivity/impulsivity subscales. Total Scores range from 0-54 (range of 0-27 for the inattention and hyperactivity subscales; 0-36 for the ADHD Index) with higher scores indicating more impaired participants. The scale was administered by a physician/PhD at the investigative site.	Baseline, 1 week	No
Secondary	Change From Baseline to 2 Weeks of Titration in the CAARS-Inv:SV Total Attention Deficit Hyperactivity Disorder (ADHD) Symptoms and Subscale Scores	30-item scale containing 3 subscales: inattention (9 items), hyperactivity/ impulsivity (9 items), and ADHD Index (12 items). Each item is scored 0-3 (0=not at all/never; 1=just a little/once in a while; 2=pretty much/often; 3=very much/very frequently). Total ADHD symptoms score=sum of the inattention and hyperactivity/impulsivity subscales. Total Scores range from 0-54 (range of 0-27 for the inattention and hyperactivity subscales; 0-36 for the ADHD Index) with higher scores indicating more impaired participants. The scale was administered by a physician/PhD at the investigative site.	Baseline, 2 weeks	No
Secondary	Change From Baseline to After a 2-Week Titration Period Beginning at Week 24 and Ending at Week 26 in the CAARS-Inv:SV Total Attention Deficit Hyperactivity Disorder (ADHD) Symptoms and Subscale Scores: Dosing Titration Strategy After Placebo	30-item scale containing 3 subscales: inattention (9 items), hyperactivity/ impulsivity (9 items), and ADHD Index (12 items). Each item is scored 0-3 (0=not at all/never; 1=just a little/once in a while; 2=pretty much/often; 3=very much/very frequently). Total ADHD symptoms score=sum of the inattention and hyperactivity/impulsivity subscales. Total Scores range from 0-54 (range of 0-27 for the inattention and hyperactivity subscales; 0-36 for the ADHD Index) with higher scores indicating more impaired participants. The scale was administered by a physician/PhD at the investigative site.	Baseline, after 2-week titration period beginning at Week 24	No
