About this study

Official title: A Double-Blind, Randomized Study to Evaluate the Efficacy and Safety of Lapaquistat Acetate 50 mg, 100 mg or Placebo When Coadministered With Rosuvastatin 10 mg or 20 mg in Subjects With Primary Hypercholesterolemia

The purpose of this study is to evaluate lapaquistat acetate, once daily (QD), taken alone or with rosuvastatin on cholesterol levels in treating patients with elevated cholesterol.

Read the detailed description

Elevated plasma cholesterol (hypercholesterolemia) and various other plasma lipid imbalances (dyslipidemias) are major risk factors for coronary heart disease. Patients with hypercholesterolemia have elevated low-density lipoprotein cholesterol, which leads to atherosclerotic deposition of cholesterol in the arterial walls. As identified by the National Cholesterol Education Program Adult Treatment Panel III, lowering the low-density lipoprotein cholesterol plasma concentration effectively reduces cardiovascular morbidity and mortality and is essential for the prevention and management of coronary heart disease.

Currently, 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors (statins) are the first-line monotherapies prescribed to reduce low-density lipoprotein cholesterol, after diet and therapeutic lifestyle change. However, low doses of statins often fail to produce the ATP III-recommended levels of low-density lipoprotein cholesterol reduction, making it necessary to increase the dose or add an additional treatment. Dose increases of statins in turn may result in decreased tolerability and potential safety concerns which contribute to the high discontinuation rates of statins and their prescription at low, and often ineffective, doses.

The purpose of this study is to determine whether administration of lapaquistat acetate co-administered with rosuvastatin will be more efficacious in lowering low-density lipoprotein cholesterol, compared to lapaquistat or rosuvastatin alone. Total participation time in this study is anticipated to be 24 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lapaquistat acetate and rosuvastatin and Rosuvastatin in people with Hypercholesterolemia, run by Takeda at 92 sites in 2 countries.

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 5 inclusion and 19 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 24 May 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 92 sites in United States, Canada. 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?

Change from Baseline in Low Density Lipoprotein cholesterol (time frame: Week 24 or Final Visit). 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 NCT00249912, which also lists 1 linked publication.

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 24 May 2012.
