Rho Kinase in Patients With Atherosclerosis

Status Completed

Clinical Trial Summary

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.

Clinical Trial 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
