E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary: functional Magnetic Resonance Imaging (fMRI): To assess the effect of atomoxetine given orally once daily (QD) for approximately 16 weeks versus (vs) placebo in children and adolescents with Dyslexia alone, ADHD+D, or ADHD alone on brain activation patterns during fMRI patients perform the tasks of pseudoword rhyming and semantic-category tasks and the Stroop attention task. The primary efficacy measures are:
- To assess the effect of atomoxetine vs placebo on Word Attack as measured by the Woodcock Johnson III Tests of Achievement (WJ III) in children and adolescents with Dyslexia alone for
approximately 16 weeks
- To assess the effect of atomoxetine vs placebo on the treatment of ADHD as measured by the ADHD Rating Scale IV (ADHDRS-IV) in children and adolescents with ADHD+D or ADHD
alone for approximately 16 weeks |
|
E.2.2 | Secondary objectives of the trial |
1.To assess the effect of atomoxetine vs placebo in patients with Dyslexia alone for approximately 16 weeks on basic reading and vocabulary.
2.To assess the effect of atomoxetine vs placebo in patients with ADHD+D or ADHD alone for approximately 16 weeks on 1) Executive Functioning as measured by the Brown Attention Deficit Disorder Scale-Adolescents (BADD-A)
3.The secondary objectives of the study at 16 weeks in the Dyslexia-alone group, ADHD+D and ADHD-alone groups to evaluate the effects of atomoxetine vs placebo in children and adolescents on measures of WJ III, the Comprehensive Test of Phonological Processing(CTOPP), the Gray Oral Reading Test-4(GORT-4), the Test of Word Reading Efficiency(TOWRE), the Working Memory Test Battery for Children(WMTB-C), the BADD-A, and the ADHD Rating Scale IV-Parent Version: Investigator Administered and Rated
4.To assess safety and tolerability.
5.Assessment of atomoxetine on brain activation patterns during fMRI from baseline to endpoint.
