Trial summary

The purpose of this study was to test the hypothesis that the long-term use of highly (>98%) purified EPA, in addition to HMG-CoA reductase inhibitor (statin), would be more effective than statin alone in preventing cardiovascular events in Japanese patients with hypercholesterolemia.

Who may be able to join

  • Eligible participants had a total cholesterol level of ≧250mg/dL(6.5m mol/L) at baseline.
  • Hyperlipidemic patients with serum total cholesterol of 250mg/dL or more. (Measurement of serum total cholesterol)

About this study

Official title: Effect of Eicosapentaenoic Acid (EPA) on Major Cardiovascular Events in Hypercholesterolemic Patients: the Japan EPA Lipid Intervention Study (JELIS)

The purpose of this study was to test the hypothesis that the long-term use of highly (>98%) purified EPA, in addition to HMG-CoA reductase inhibitor (statin), would be more effective than statin alone in preventing cardiovascular events in Japanese patients with hypercholesterolemia.

Read the detailed description

Epidemiological studies from many countries including Finland, Italy, Japan, and The Netherlands have suggested that an increased intake of dietary fish or fish oil rich in the long-chain polyunsaturated n-3 fatty acids (PUFAs), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), is inversely related to the risk of atherothrombotic diseases, in particular coronary artery disease (CAD).

Results of many prospective observational cohort studies have found that diets rich in marine PUFAs may be protective against major cardiovascular events, including mortality from CAD, total cardiovascular death, all-cause mortality, and nonfatal myocardial infarction. To date, only a few studies have examined the effects of purified n-3 PUFA preparations in human subjects for short observation periods. The principle aim of the current study is to test the hypothesis that the long-term use of highly purified EPA(eicosapentaenoic acid: 1800mg/day), in addition to HMG-CoA reductase inhibitor, is effective in preventing cardiovascular events in Japanese patients with hypercholesterolemia.

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 15 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 20 Nov 2015. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Major coronary events (sudden cardiac death, fatal and nonfatal myocardial infarction, unstable angina pectoris including hospitalization for ischemic episodes,events of angioplasty/ stenting or coronary artery bypass grafting). 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 NCT00231738, which also lists 8 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 20 Nov 2015.
