About this study
Official title: Rho Kinase in Patients With Atherosclerosis: Effects of Statins - A Double Blind, Randomized Clinical Trial Comparing Rosuvastatin and Atorvastatin
The purpose of the study is to investigate the effects of atorvastatin (Lipitor) and rosuvastatin (Crestor), United States Food and Drug Administration (FDA) approved drugs commonly prescribed by doctors to lower cholesterol, on certain functions of platelets (cells that cause blood clots), white blood cells (cells that are responsible for inflammation), and blood flow regulation by arteries. This is important because we are looking at ways to more effectively prevent atherosclerosis (plaque buildup in blood vessels) and heart disease. Many studies have demonstrated that these drugs are effective at reducing inflammation and stabilizing plaques. We are interested in better understanding the effects of these medicines on inflammation (pain and swelling) and the mechanism by which they act.
Hypothesis: Atorvastatin (40mg) will reduce inflammatory markers and activity more than Rosuvastatin (10mg) in spite of equal LDL-C reduction.
Read the detailed description
A double-blind controlled trial with two arms will be conducted at Brigham and Women's Hospital (BWH). We will screen subjects with stable atherosclerosis to complete enrollment of 40 subjects in the study (see inclusion and exclusion criteria section below). A central pharmacist at BWH will randomize the patients to 40mg of atorvastatin (n=20) or 10mg of rosuvastatin (n=20) for 28 days. If the patient is already on a statin a two-week washout period will be required prior to trial initiation. Our subjects, clinicians, data collectors, outcomes assessors and statisticians will be blind with regards to the patient allocation. There are a total of 3 visits for each patient: a short screening visit, an initial visit for baseline data (90 min.) and a final visit after 28 days. Our participants will be asked to take the medication every day at the same time between 9pm and 10pm. Each visit will take place between 7am and 9am. Patients will be instructed to fast overnight for a minimum of 8hrs. They will also be advised not to make any other changes to their current medications and lifestyle for 28 days while in the study and to record in a diary any side effects, missed doses, or changes in concomitant medication.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Atorvastatin and Rosuvastatin in people with Atherosclerosis, run by Brigham and Women's Hospital 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 5 inclusion and 8 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 Apr 2007. 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 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.
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 24 Apr 2007.
