About this study

Official title: A Double-blind, Randomized Study to Evaluate the Efficacy and Safety of TAK-475 or Placebo When Coadministered With Fenofibrate in Subjects With Combined Hyperlipidemia

The purpose of this study is to compare changes in cholesterol levels in patients with elevated blood cholesterol with administration of lapaquistat acetate, once daily (QD), and fenofibrate.

Read the detailed description

Elevated plasma cholesterol (hypercholesterolemia) and various other plasma lipid imbalances (dyslipidemias) are major risk factors for coronary heart disease. It has been established that lowering the low-density lipoprotein cholesterol plasma concentration effectively reduces cardiovascular morbidity and mortality. As a result of this finding, the National Cholesterol Education Program Adult Treatment Panel III identifies control of low-density lipoprotein cholesterol as essential in 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 Adult Treatment Panel III-recommended levels of low-density lipoprotein cholesterol reduction, making it necessary to increase the dose or add an additional treatment. This in turn may result in decreased tolerability and potential safety concerns.

At higher doses, statins are associated with various myopathies ranging from rare occurrences of rhabdomyolysis and myositis to more frequent symptoms of muscle weakness, cramps, or pain; these can occur with mild or no increases in creatine kinase. Statin use also is associated with increases in liver transaminase levels. These tolerability and safety concerns may contribute to the high discontinuation rates of statins and their prescription at low, and often ineffective, doses.

TAK-475 (lapaquistat acetate) inhibits the cholesterol synthesis pathway at a different step than statins (acting on squalene synthase rather than 3-hydroxy-3-methylglutaryl coenzyme A); it does not reduce concentrations of isoprenylated intermediates believed to be responsible for the myopathies associated with statin use.

This study was conducted to determine whether lapaquistat acetate with fenofibrate has the potential to be more effective than fenofibrate by itself in lowering low-density lipoprotein cholesterol.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lapaquistat acetate and fenofibrate and Fenofibrate in people with Hyperlipidemias, run by Takeda at 36 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 23 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 36 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Percent change from Baseline in direct fasting plasma low-density lipoprotein cholesterol. (time frame: Week 12 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 NCT00813527, 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.
