- Conditions
- Attention Deficit Hyperactivity Disorder (ADHD)
- Interventions
- Drug: Placebo
- Registration Number
- NCT02477748
- Lead Sponsor
- Alcobra Ltd.
- Brief Summary
This study is a multi-center, randomized, double-blind, placebo-controlled, phase 3 study of MDX (1400 mg daily) for 10 weeks compared with placebo in adults with ADHD.
The study will be comprised of Screening, Washout (if required), Treatment (total of 10 weeks) and Follow-up periods. Approximately 750 patients will be enrolled and undergo initial eligibility assessments.
- Detailed Description
* A 10-week randomized, multi-center, double-blind, placebo-controlled, phase 3 study of MDX (1400 mg daily) for 10 weeks compared with placebo in adults with ADHD.
* The study will be comprised of Screening, Washout (if required), Treatment (total of 10 weeks) and Follow-up periods. Approximately 750 patients will be enrolled and undergo initial eligibility assessments.
* Subjects requiring a washout will undergo a Washout period where ADHD medication is discontinued (21 days for atomoxetine, 14 days for other ADHD medications). These subjects will have an Interim Visit (off drug) on or about Day -10 (Day -10 to Day -3) for CAARS-Inv assessment at the end of the Washout period.
* Subjects will be randomly assigned to placebo/MDX for a total treatment duration of up to ten weeks.
There will be a one week Follow-up period after the last dose of study treatment or early termination.
