What is being measured

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

  1. Simulated Driver Safety (DS) Score averaged over 3 driving assessments at one interim and one final visit.

    Measured: Interim visit = Week 3; Final visit = Week 7.

Secondary outcomes (3)
  1. Interim & final visits: Attention-Deficit Hyperactivity Disorder Rating Scale - 4th Edition (ADHD-RS-IV)

    Measured: Interim visit = Week 3; Final visit = Week 7.

  2. Interim & final visits: Clinical Global Impressions of Improvement (CGI-I)

    Measured: Interim visit = Week 3; Final visit = Week 7.

  3. Interim & final visits: Self-Rating of Simulated Driver Safety (DS) Performance Questionnaire

    Measured: Post DS Testing - Interim visit = Week 3; Post DS Testing - Final visit = Week 7.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing SPD465 in people with Attention Deficit Hyperactivity Disorder, run by Shire at 1 site 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 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: withdrawn, as of the sponsor's last update on 6 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Simulated Driver Safety (DS) Score averaged over 3 driving assessments at one interim and one final visit. (time frame: Interim visit = Week 3; Final visit = Week 7.). 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 6 Jul 2021.
