The ADHDRS-IV consists of 18 items designed to reflect symptoms of ADHD. Each item is scored on a scale of 0 (Never or rarely) to 3 (Very Often). The subscales of the ADHDRS-IV included the Inattention and the hyperactivity/Impulsivity subscales (total possible score range, 0-54). The Inattention subscale consists of the sum of 9 items: 1, 3, 5, 7, 9, 11, 13, 15, and 17. The Hyperactivity/Impulsivity subscale consists of the sum of 9 items: 2, 4, 6, 8, 10, 12, 14, 16, and 18

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing CLONICEL (Clonidine HCl sustained release) in people with Attention Deficit Hyperactivity Disorder, run by Shionogi at 27 sites in United States.

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 6 inclusion and 6 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 18 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 27 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 27 Feb 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety Assessment in Terms of Adverse Events (Treatment-emergent [TEAEs] and Serious [SAEs]) (time frame: 1 year). The study lists 9 primary outcomes in all. 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 NCT00723190.

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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Apr 2018.
