About this study

Official title: Red Yeast Rice vs. Pravastatin: A Double-Blind Randomized Comparative Study of Myopathic Symptoms

This study will examine the effect of red yeast rice extract compared to pravastatin on muscle related complaints in individuals with high cholesterol who have previously been unable to tolerate statin medications due to muscle pain. The study will determine whether red yeast is associated with a lower level of muscle related complaints compared to pravastatin.

Read the detailed description

20 million Americans are actively treated with statins at an annual cost of 16 billion dollars. Statins are effective therapeutic agents for reducing LDL cholesterol and have documented effectiveness. However, a significant subset of patients (5-18%), cannot tolerate lipid lowering statin therapy due to intolerable muscle-related symptoms characterized by muscle pain and/or weakness. These symptoms affect quality of life and lead to poor adherence.

Patients may seek alternative therapies to manage hypercholesterolemia if they have been intolerant of statin therapy. One commonly used alternative treatment option is the Chinese herb red yeast rice extract. Several small studies performed in China, have suggested this treatment is efficacious and well tolerated. In the U.S. red yeast rice is sold over the counter a dietary supplement.

The objective of this study is to critically examine the safety and efficacy of the Chinese herb red yeast rice as an alternative lipid lowering therapy, in a statin intolerant population.

This objective will be operationalized by a double-blind randomized trial, comparing the effect of red yeast rice extract, to that of pravastatin on the level of myalgia in subjects with a prior history of statin-induced myalgias.

The specific aims include:

  1. Determine the relative rates of withdrawal from treatment in subjects receiving red yeast rice compared to pravastatin.
  2. Determine if red yeast rice is associated with a lower level of muscle pain (myalgia) symptoms compared to pravastatin as measured by the Brief Pain Inventory, a validated pain questionnaire.
  3. Determine if red yeast rice is associated with a lower level of muscle weakness compared to pravastatin as measured by a dynamometry, a validated muscle strength testing method.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Red Yeast Rice, Pravastatin and Lifestyle modification program in people with Hypercholesterolemia and Statin-Associated Myopathy, run by University of Pennsylvania at 1 site in United States.

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 3 inclusion and 7 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 18 Jan 2010. 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 United States. 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?

Yes. Results are posted in the registry (first posted 18 Jan 2010). 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?

Withdrawal of Therapy Due to Muscle Symptoms That Are Either Intolerable and/or Associated With a Creatine Kinase(CK) >500 (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 Jan 2010.
