Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of this study is to test the hypothesis that atomoxetine given orally once daily for approximately 16 weeks will provide superior efficacy compared to placebo for the treatment of ADHD in children and adolescents with ADHD and comorbid Dyslexia (ADHD+D) as measured by the Attention-Deficit/Hyperactivity Disorder Rating Scale-IV-Parent Version: Investigator-Administered and Scored (ADHDRS-IV-Parent:Inv).;Secondary Objective: 1) To assess the effect of atomoxetine versus placebo for approximately 16 weeks on the secondary measures (see section E.5.2) 2) To assess the safety and tolerability of atomoxetine over approximately 16 and 32 weeks in the ADHD alone group, ADHD+D group, and dyslexia alone group as assessed by laboratory, vitals, and ECG measures and adverse events elicited during open-ended questioning.;Primary end point(s): Change From Baseline in Attention-Deficit/Hyperactivity Disorder Rating Scale (ADHDRS) Total Score - Parent Version at Week 16 Endpoint ;Timepoint(s) of evaluation of this end point: Baseline, 16 weeks
