    Participants will be asked to self-administer one atorvastatin 10 mg or 80 mg tablet at approximately the same time each day.

  • placeboDrug

    Participants will be asked to self-administer one tablet of placebo to atorvastatin 10 mg or 80 mg at approximately the same time each day.

What is being measured

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

  1. Percent Reduction From Baseline in TBRmeanmax of the Qualifying Segment

    Vascular plaque inflammation was measured by 18FDG-PET imaging. Uptake of FDG by the carotid and thoracic aorta is expressed as the target, vessel wall to background, lumen ratio (TBR). TBRmax of an axial cross section of a vessel (a slice) is defined as the maximum TBR within a slice and TBRmeanmax is the mean of TBRmax for all slices in the qualifying segment. The qualifying segment is the left or right carotid or thoracic aorta with the greatest FDG uptake value at Baseline.

    Measured: Baseline and Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing atorvastatin in people with Atherosclerotic Vascular Disease, run by Merck Sharp & Dohme LLC.

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 2 inclusion and 4 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 9 Oct 2015. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 30 Nov 2011). 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?

Percent Reduction From Baseline in TBRmeanmax of the Qualifying Segment (time frame: Baseline and Week 12). 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 NCT00703261, which also lists 3 linked publications.

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 9 Oct 2015.
