• Male and female subjects, 18-45 years of age at the time of consent meeting diagnostic criteria of Attention Deficit Hyperactivity Disorder (ADHD) per Diagnostic and Statistical Manual of Mental Disorders (DSM-5) at screening visit and currently undergoing diagnostic assessment and/or treatment for ADHD
• Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the trial
• A diagnosis of the moderate symptoms of ADHD confirmed with combined score of 4 or higher in Clinical Global Impression-ADHD-Severity (CGI-ADHD-S) at Screening; Hyperactivity/Impulsivity subscale min 8 (at least moderate for impulsivity measure with ADHD checklist)
• Able and willing to discontinue the use of any psychotropic medications for treatment of ADHD symptoms, as well as of all relevant co-medication for comorbid conditions during the study
• Women of childbearing potential (WOCBP) [1] must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria and instructions on the duration of their use is provided in the patient information; A woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. Tubal ligation is NOT a method of permanent sterilisation
