About this study

Official title: Japan Assessment of Pitavastatin and Atorvastatin in Acute Coronary Syndrome

The purpose of this study is to compare the effects of pitavastatin and atorvastatin on coronary plaque volume in patients with acute coronary syndrome and to clarify the relationship between coronary plaque volume, serum lipids, and inflammation markers in order to determine the significance of intensive lipid lowering therapy in patients with acute coronary syndrome in Japan.

Read the detailed description

Previous mega trials have demonstrated that lipid lowering therapy with HMG-CoA reductase inhibitors (statins) reduces the incidence of major cardiovascular events by one-third, thus, the benefit of lipid lowering therapy has been substantiated. Such a benefit is significant especially for patients with coronary heart disease (CHD). The third report of the National Cholesterol Education Program Adult Treatment Panel (NCEP ATP-III) has suggested the advantage of more intensive lipid lowering therapy with a goal of reducing LDL-C below 70 mg/dL for such patients categorized as very high risk. In Japan, Japan Atherosclerosis Society (JAS) Guidelines for Diagnosis and Treatment of Atherosclerotic Cardiovascular Diseases 2002 have recommended that an LDL-C goal for patients with coronary heart disease should be below 100 mg/dL. However, there is no satisfactory evidence yet for the need to lower LDL-C level less than the goal prescribed in Japan.

Recently, research on diagnosis of coronary plaque has shown significant advances. The REVERSAL study in patients with a history of CHD, by diagnosis with intravascular ultrasound, suggested that intensive lipid lowering therapy with atorvastatin (80 mg/day) was associated with no growth of plaque (-0.4% compared to baseline), versus therapy with pravastatin (40 mg/day) which showed a slight increase (2.7%) in plaque volume over 18 months. In Japan, the ESTABLISH study, a single center study, indicated that early intensive lipid lowering therapy with atorvastatin (20 mg/day) could induce a significant reduction in plaque volume in patients with acute coronary syndrome. However, this benefit has not been verified in multicenter trials in Japan. Further, no comparative investigation into the effect of various concomitant drugs on coronary plaque has been done.

Pitavastatin is a chemically synthesized statin in Japan which has been marketed since late 2003. Pitavastatin has an LDL-C lowering effect as strong as atorvastatin and also has a superior HDL-C elevating effect; meanwhile, the effect of pitavastatin on coronary plaque has not been reported.

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 9 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 4 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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 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?

plaque volume (time frame: one year). 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 NCT00242944, which also lists 6 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 4 Oct 2023.
