Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
The study consisted of 4 treatment periods: 12 weeks open-label, acute-treatment (trx) phase (Study Period 2), 12 weeks double-blind maintenance phase of Study Period 3 (Study Period 3A), 25 weeks double-blind randomized withdrawal phase of Study Period 3 (Study Period 3B) and an Open-Label Extension Period (Study Period 4) lasting up to 2.3 years.

Reporting Groups
  Description
Atomoxetine (Study Period 2) 40-100 milligrams/day (mg/day) atomoxetine orally, once daily or twice daily for 12 weeks during open-label, acute-treatment phase (Study Period 2).
Atomoxetine (Study Period 3A) 40-100 milligrams/day (mg/day) atomoxetine orally, once daily or twice daily for 12 weeks during double-blind randomized withdrawal phase (Study Period 3).
Atomoxetine (Study Period 3B) 80-100 mg/day atomoxetine orally, once daily or twice daily for 25 weeks during double-blind randomized withdrawal phase of Study Period 3 (Study Period 3B).
Placebo (Study Period 3B) Placebo orally, once daily or twice daily for 25 weeks during double-blind randomized withdrawal phase of Study Period 3 (Study Period 3B).
Atomoxetine (Study Period 4) Participants who received either atomoxetine or placebo and completed the last visit of Study Period 3 who were in countries where the adult ADHD indication for atomoxetine was not approved were allowed to participant in Study Period 4 (Open-label Extension). Participants received 40 mg/day atomoxetine orally for at least 7 days after which it was increased to 80-100 mg/day atomoxetine orally for up to 2.3 years.
