About this study

Official title: Secondary Prevention With HMG-CoA Reductase Inhibitor Against Stroke

Although hyperlipidemia is not always the risk factor of stroke, inhibition of 3-hydroxy-3-methylglutaryl-coenzyme A(HMG-CoA) reductase can decrease the incidence of stroke in the patient with ischemic heart disease. The neuroprotective mechanism beyond cholesterol lowering should be expected to attenuate inflammation and atherosclerosis. The present study hypothesizes if pravastatin prevents recurrent stroke in the ischemic stroke patients with safety.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Pravastatin in people with Ischemic Stroke, run by Translational Research Center for Medical Innovation, Kobe, Hyogo, Japan at 1 site 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 8 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 Jan 2018. 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 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?

Yes. Results are posted in the registry (first posted 25 Jan 2018). 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?

Incidence Rate of Stroke and TIA (time frame: up to 5 years). 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 NCT00221104, 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 Jan 2018.
