Study Endpoints

Primary Endpoints

Change From Baseline in Attention Deficit Hyperactivity Disorder Rating Scale, Version 5 (ADHD-RS-5) Total Score
Baseline to Visit 8 (Week 6)

The ADHD-RS-5 is comprised of 18 frequency items and 12 impairment items. Each frequency item was scored on a scale from 0 = "Never or rarely" to 3 = "Very often". The ADHD-RS-5 total score was calculated as the sum of the 18 frequency item scores. The total score ranges from 0 to 54. Higher scores indicate greater symptom severity. Change from baseline value were calculated as the assessment value minus the baseline value.

Clinical Global Impression - Global Improvement (CGI -I) Response
Visit 3 to Visit 8 (Week 6)

The CGI-I item is rated on a 7-point scale from 1 = "Very much improved", 2 = "Much improved", 3 = "Minimally improved", 4 = "No change", 5 = "Minimally worse", 6 = "Much worse", 7 = "Very much worse". Response is defined as achieving a CGI-I score of 1 or 2, scores of 3 to 7 or missing are defined as Non Response
