ABSTRACT
Objective: To assess the broader efficacy (i.e., improvements in quality of life/functional outcomes) of atomoxetine compared with standard current therapy (SCT) in UK paediatric patients with ADHD and to explore clinician/parent/child perceptions of ADHD.
Research design and methods: A total of 201 patients with ADHD were randomised into this multi-centre, open-label study to receive atomoxetine (n = 104) or SCT (n = 97) for 10 weeks. Broader efficacy was assessed using the parent-rated Child Health and Illness Profile-Child Edition (CHIP‑CE) total (global) t-score. Secondary outcome measures included the five CHIP‑CE domains; parent-rated Family Burden of Illness Module (FBIM); investigator-rated ADHD‑Rating Scale; investigator-rated Clinical Global Impression (CGI)-Severity/Improvement scales; and child-rated Harter Self-Perception Profile (HSPP).
Results: Quality of life of children/adolescents with ADHD was extremely compromised at baseline (CHIP‑CE total t-scores: atomoxetine, 23.2 ± 12.2; SCT, 23.9 ± 11.0), and improved during the 10-week study for both groups; the CHIP‑CE score was statistically significantly higher for patients treated with atomoxetine (38.4 ± 1.3) compared with SCT (30.8 ± 1.3) at week 10 ( p < 0.001). ADHD‑RS, CGI-Severity, and CGI-Improvement scores were significantly different between the groups in favour of atomoxetine ( p < 0.001). There was a statistically significant difference between the groups in the HSPP Social Acceptance domain in favour of atomoxetine, but not in the five other HSPP domains or FBIM total score. Atomoxetine was well-tolerated.
Conclusions: Results from this open-label trial show that atomoxetine is superior to SCT in addressing broader efficacy and functional outcomes in UK children/adolescents with ADHD. This study contributes to the understanding of broader efficacy in children with ADHD, and is timely in light of recent NICE guidance.
