March 11, 2013 updated by: Makoto Ayaori, National Defense Medical College, Japan

Effect of Atorvastatin on Inflammatory Atherosclerotic Plaques Assessed by FDG-PET Imaging

The purpose of this study is to determine whether HMG-CoA reductase inhibitor, atorvastatin attenuates inflammation in atherosclerotic plaques detected by 18F-fluorodeoxyglucose(FDG) PET.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
30

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
ACTIVE_COMPARATOR: Atorvastatin
Drug: Atorvastatin
Subjects are advised to keep dietary habits according to the National Cholesterol Education Program (NCEP) from the run-in period throughout the study. The subjects are administered with 10mg/day for 3 months, if LDL-cholesterol levels does not decrease less than 80mg/dl, the dose is increased up to 20mg/day. If LDL-cholesterol levels decrease less than 60mg/dl, the dose is decreased down to 5mg/day or less.
Other Names:
  • Lipitor
PLACEBO_COMPARATOR: Lifestyle counseling
Subjects are advised to keep dietary habits according to the National Cholesterol Education Program (NCEP) from the run-in period throughout the study.
Behavioral: Lifestyle counseling
Subjects are advised to keep dietary habits according to the National Cholesterol Education Program (NCEP) from the run-in period throughout the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Standardized uptake value (SUV) of 18-FDG detected in carotid/aortic atherosclerotic plaques
Time Frame: Baseline and 3 months after intervention
Baseline and 3 months after intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Flow-mediated vasodilation of brachial artery determined by ultrasonography
Time Frame: Baseline and 3 months after intervention
Baseline and 3 months after intervention
Serum markers for inflammation such as high-sensitive CRP, IL-6 or soluble ICAM-1
Time Frame: Baseline and 3 months after intervention
Baseline and 3 months after intervention
Serum and urine markers for anti- or pro-oxidant stress such as oxidized LDL or 8-Hydroxydeoxyguanosine
Time Frame: Baseline and 3 months after intervention
Baseline and 3 months after intervention
Max-intima-media thickness (Max-IMT), Mean-IMT and plaque score determined by carotid artery ultrasonography
Time Frame: Baseline and 3 months after intervention
Baseline and 3 months after intervention
Serum lipids such as total cholesterol, LDL-cholesterol, HDL-cholesterol, RLP-cholesterol and triglycerides
Time Frame: Baseline and 3 months after intervention

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
