About this study
Official title: Rosiglitazone and Plaque Study: A 12 Month Randomised, Double-blind, Placebo-controlled, Magnetic Resonance Imaging Study to Evaluate the Effect of Rosiglitazone on the Structure and Composition of Carotid Atherosclerotic Plaques in Subjects With Type 2 Diabetes Mellitus and Coexisting Vascular Disease or Hypertension
This is a phase IIIb, randomised, double blind, placebo controlled, study in patients with type 2 diabetes mellitus and coexisting vascular disease or hypertension. The total duration of the study will be approximately 60 weeks. The aim of this study is to examine the potential beneficial effects of rosiglitazone on carotid atheroma in patients with type 2 diabetes mellitus and coexisting vascular disease or hypertension. It is hypothesised that treatment with rosiglitazone will lead to an decrease in plaque size. In addition, it is hoped that rosiglitazone will have a positive effect on plaque composition and stability.

What is being measured
The primary outcome is the main question the study is designed to answer.
The effect of 52 wks oral treatment with rosiglitazone in comparison to placebo on change from baseline of the plaque total wall volume in the carotid artery, in patients with type 2 dm and vascular disease/hypertension, using cardiac mri.
Measured: 52 Weeks
Secondary outcomes (1)
These include magnetic resonance endpoints related to plaque lipid content, volume, plaque size and fibrous cap thickness. Colour duplex measurements, laboratory assays for glycaemia and lipids.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing rosiglitazone in people with Non-insulin-dependent Diabetes Mellitus, run by GlaxoSmithKline at 1 site in United Kingdom.
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 4 inclusion and 7 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 23 Jan 2017. 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 Kingdom. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
The effect of 52 wks oral treatment with rosiglitazone in comparison to placebo on change from baseline of the plaque total wall volume in the carotid artery, in patients with type 2 dm and vascular disease/hypertension, using cardiac mri. (time frame: 52 Weeks). 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 23 Jan 2017.
