What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Attention-Deficit/Hyperactivity Disorder Rating Scale, Fourth Edition (ADHD-RS-IV) Total Score at Week 6
The ADHD-RS-IV was developed to measure the behaviors of children with ADHD and is commonly used in clinical studies of ADHD. The ADHD-RS-IV consisted of 18 items designed to reflect current symptomatology of ADHD based on Diagnostic and Statistical Manual of Mental Disorders, 4th Edition-Text Revision (DSM-IV-TR) criteria. Each item was scored on a 4-point scale ranging from 0 (reflecting no symptoms) to 3 (reflecting severe symptoms) with total scores ranging from 0-54, Higher score = more severe symptoms.
Measured: Baseline, Week 6
Secondary outcomes (1)
Percentage of Participants With an Improvement on Clinical Global Impression - Global Improvement (CGI-I) at Week 6
The Clinical Global Impressions Scale permits a global evaluation of the participant's severity of illness and improvement over time. The scale included a severity of illness item and a global improvement item. The investigator performed the CGI-I to rate the improvement of a participant's ADHD symptoms based on a 7-point scale (1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; or 7=very much worse.). Percentage of participants with an improved measurement (response of very much improved and much improved) is reported.
Measured: Week 6

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 Mar 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

What does the primary outcome measure?
Change From Baseline in Attention-Deficit/Hyperactivity Disorder Rating Scale, Fourth Edition (ADHD-RS-IV) Total Score at Week 6 (time frame: Baseline, Week 6). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01552902, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
