Attention Deficit Hyperactivity Disorder

Brief summary

Double blinded clinical trial placebo controlled in 153 children (planned enrollment) with recent diagnosis of ADHD. Patients will be randomized to atomoxetine or placebo arm (2:1). The double blinded period will last 12 weeks and the treatment open phase will last up to 1 year, and atomoxetine treatment will be administered. A gatekeeper strategy will be employed for sequentially testing the secondary objectives.

Inclusion criteria

1. Child or adolescent patients must be at least 6 years of age, but must not yet have reached their 16th birthday prior to Visit 1, when informed consent is obtained. 2. Patients must meet the Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition Text Revision (DSM-IV-TR) diagnostic criteria for ADHD. For the purposes of this study the diagnosis of ADHD will be confirmed during Visit 1 by administering the K-SADS-PL. Patients must also have an ADHDRS-IV-Parent:Inv score at least 1.5 standard deviations above the age norm for their diagnostic subtype at both Visit 1 and Visit 2. In addition, they must have a CGI-ADHD-S score 4 at both Visit 1 and Visit 2. 3. Patients must have a newly diagnosed case of ADHD. Newly diagnosed case of ADHD means that a specialist (including pediatrician, child psychiatrist, or child neurologist) or child psychologist has diagnosed ADHD (according DSM-IV-TR or International Statistical Classification of Diseases and Related Health Problems \[World Health Organisation; 10th Revision\] \[ICD 10\] criteria) within 3 months prior to Visit 1.

Exclusion criteria

1. Patients with history of ADHD diagnosis longer than 3 months prior to Visit 1. Diagnosis of ADHD means that a specialist (including pediatrician, child psychiatrist, or child neurologist) or child psychologist has diagnosed ADHD (according DSM-IV-TR or ICD 10 criteria) and has registered it in medical records or verbally informed parents about this diagnosis. 2. Patients who weigh less than 20 kg at study entry (Visit 1). If a patient's weight changes after Visit 1 to a value outside of the stated range, the patient will still be eligible, and the weight should be rounded to the nearest value within the above range for dosing purposes.

It consists of 76 items. The majority of items assess frequency of activities or feelings using a five-point response format (for example, 'how good is your child at making friends?' 1=never, 5=always). Standard scores (t-value) were established, with all domains and subdomains having a mean score of 50 and standard deviation of 10. Standard scores are expressed in standard deviation units. T-score=\[(Score-4.2382)\*10/0.32835\]+50. Higher scores mean improvement.

Conners' Parent Rating Scale-Revised: Short Form (CPRS-R:S) Total Score Changes From Baseline to Endpoint (Week 12)

The CPRS-R:S has 27 items to be completed by the parent to assess behavioral problems related to ADHD. Individual item scores range from 0 (not at all true/never/seldom: lowest impairment) to 3 (very much true/very often/very frequent: highest impairment). The total score is calculated as the sum of all items. Total scores range from 0 to 81.
