Carotid Intima-media Thickness in Japan Statin Treatment Against Recurrent Stroke(J-STARS Echo)
A Phase 3 study testing Statin in people with Ischemic Stroke, run by Translational Research Center for Medical Innovation, Kobe, Hyogo, Japan at 2 sites in Japan.
Trial summary
Carotid ultrasound can reveal the intima-media complex thickness(IMT), that has been reported to be a marker of atherosclerosis as well as a risk of cardiovascular events, and to be attenuated by 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) .

About this study
Official title: Effect of 3-hydroxy-3-methylglutaryl-coenzyme A(HMG-CoA) Reductase Inhibitor Upon Carotid Intima-media Complex Thickness in the Post-ischemic Patients With Hyperlipidemia During the Prospective Study of J-STARS.
Carotid ultrasound can reveal the intima-media complex thickness(IMT), that has been reported to be a marker of atherosclerosis as well as a risk of cardiovascular events, and to be attenuated by 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) . This substudy of J-STARS will observe the temporal profile of carotid IMT prospectively in the patients with prescription of pravastatin and the control.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Statin in people with Ischemic Stroke, run by Translational Research Center for Medical Innovation, Kobe, Hyogo, Japan at 2 sites in Japan.
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 12 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 25 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Japan. 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?
Intima-media complex thickness (IMT) of the common carotid artery (CCA) (time frame: until the last day of the next February after 5-year follow-up survey). 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 NCT00361530, 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 25 Apr 2016.
