What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety Assessment in Terms of Adverse Events (Treatment-emergent [TEAEs] and Serious [SAEs])

    Safety assessments were performed at each study visit according to the time and events schedule. All safety analyses were based on safety population

    Measured: 1 year

  2. Safety Assessment in Terms of Adverse Events (Treatment-emergent [TEAEs] and Serious [SAEs])

    Safety assessments were performed at each study visit according to the time and events schedule. All safety analysis were based on safety population

    Measured: 1 year

  3. Change From Baseline in 12-lead Electrocardiogram in Terms of QT, QTc Fridericia (QTcF), and QTc Bazett's (QTcB) at Week 4

    Measured: At baseline and at Week 4

  4. Change From Baseline in Body Weight at Weeks 1, 2, 3, 4, and Months 2, 3, 4, 5, 6, 9, and 12

    Measured: At baseline and at weeks 1, 2, 3, 4, and months 2, 3, 4, 5, 6, 9, and 12

  5. Change From Baseline in Diastolic Blood Pressure at Week 4

    Blood pressure was measured with the subject in a sitting position and resting for at least 2 minutes prior to taking the measurement. The dominant arm was used for the measurement

    Measured: At baseline and at Week 4

  6. Change From Baseline in Systolic Blood Pressure at Week 4

    Blood pressure was measured with the subject in a sitting position and resting for at least 2 minutes prior to taking the measurement. The dominant arm was used for the measurement

    Measured: At baseline and at Week 4

  7. Change From Baseline in Body Temperature at Week 4

    Temperature was measured with the subject in a sitting position and resting for at least 2 minutes prior to taking the measurement

    Measured: At baseline and at Week 4

  8. Change From Baseline in Heart Rate at Week 4

    Heart rate was measured with the subject in a sitting position and resting for at least 2 minutes prior to taking the measurement

    Measured: At baseline and at Week 4

  9. Change From Baseline in 12-lead Electrocardiogram in Terms of Heart Rate at Week 4

    Measured: At baseline and at Week 4

Secondary outcomes (3)
  1. Change From Baseline in Attention Deficit Hyperactivity Disorder Rating Scale-fourth Edition (ADHDRS-IV Scale) (18 Items Scored, 0 [Never/Rarely] to 3 [Very Often]; Total Possible Score Range, 0-54) at Months 1, 2, 3, 4, 6, 9, and 12

    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

    Measured: At baseline, months 1, 2, 3, 4, 6, 9, and 12

  2. Change From Baseline in Clinical Global Impressions-Severity (CGI-S) at Months 1, 2, 3, 4, 6, 9, and 12

    CGI-S scale:

    1 = Normal, not ill at all; 2 = Borderline ill; 3 = Mildly ill; 4 = Moderately ill; 5 = Markedly ill; 6 = Severely ill; 7 = Among the most extremely ill patients

    Measured: At baseline, months 1, 2, 3, 4, 6, 9, and 12

  3. Change From Baseline in Clinical Global Impressions-Improvement (CGI-I) at Months 1, 2, 3, 4, 6, 9, and 12

    CGI-I scale:

    1 = Very much improved; 2 = Much improved; 3 = Minimally improved; 4 = No change; 5 = Minimally worse; 6 = Much worse; 7 = Very much worse

    Measured: At baseline, months 1, 2, 3, 4, 6, 9, and 12

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?
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.
