Official Title: “A Phase 3b, Randomized, Open-Label Assessment of Response to Various Doses of Atomoxetine Hydrochloride in Korean Pediatric Outpatients With Attention-Deficit/Hyperactivity Disorder”

The purpose of this study is to provide information regarding the relative effectiveness of three different atomoxetine doses in the treatment of Korean children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD)

Study Type: Interventional

Study Design: Treatment, Randomized, Open Label, Dose Comparison, Parallel Assignment, Safety/Efficacy Study

Study Primary Completion Date: November 2008

Intervention(s) in this Clinical Trial

• Drug: Atomoxetine Hydrochloride
  • Patients in Arm 1 receive 0.2 mg/kg/day atomoxetine administered orally in two divided doses for the duration of the 6-week acute treatment period
• Drug: Atomoxetine hydrochloride
  • Patients in Arm 2 receive 0.5 mg/kg/day atomoxetine administered orally in two divided doses for the duration of the 6-week acute treatment period
• Drug: Atomoxetine hydrochloride
  • Patients in Arm 3 will initially receive atomoxetine 0.5 mg/kg/day administered orally in two divided doses for approximately 7 days. Patients will then receive atomoxetine 0.8 mg/kg/day administered orally in two divided doses for approximately 7 days. Patients will receive atomoxetine 1.2 mg/kg/day administered orally in two divided doses for the remainder of the study, lasting approximately 28 days

Arms, Groups and Cohorts in this Clinical Trial

• Active Comparator: 1
• Active Comparator: 2
• Active Comparator: 3

Primary Measures

• To assess graphically dose-response with atomoxetine, as measured by change from baseline to endpoint in Attention-Deficit/Hyperactivity Disorder Rating Scale-IV-Parent Version: Investigator Administered and Scored (ADHDRS-IV-Parent:Inv) total score
  • Time Frame: Change to baseline, 6 weeks
    Safety Issue?: No

Secondary Measures

  • Time Frame: Change to baseline, 6 weeks
    Safety Issue?: No
• To assess the efficacy of each dose in reducing the severity of ADHD symptoms, as measured by Clinical Global Impression-ADHD- Improvement (CGI-ADHD-I) score at endpoint
  • Time Frame: Change to baseline, 6 weeks
    Safety Issue?: No
• To assess the safety and tolerability of atomoxetine at each dosage
  • Time Frame: Each study visit
    Safety Issue?: Yes
