A 9-Week, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Dose-Finding Study to Evaluate the Efficacy and Safety of Modafinil as Treatment for Adults With ADHD
Journal of Attention Disorders, 05/24/2012
Arnold VK et al. – Modafinil was reasonably tolerated but did not demonstrate a benefit on ADHD symptoms in adults.Methods
- Adult patients with ADHD were randomized in 1:1:1:1:1 fashion to double-blind treatment with modafinil 255, 340, 425, or 510 mg daily or placebo for 9 weeks.
- The primary efficacy outcome was the change from baseline at final visit in the Adult ADHD Investigator Symptom Rating Scale (AISRS) total score.
- A total of 338 patients were enrolled, of whom 330 received at least 1 dose of study medication (modafinil or placebo).
- No statistically significant difference in the AISRS total score was observed at final visit between any modafinil group and placebo; however, some observations among patients who completed the trial may warrant further investigation.
