Ppar-Gamma EliminAtes Restenosis Longevity Study: PEARLS

May 21, 2008 updated by: Medstar Health Research Institute

The primary objective of this clinical trial is to assess the efficacy of rosiglitazone on bare metal stent (BMS) in-stent restenosis measured as late lumen loss in patients with metabolic syndrome.

The secondary parameter for evaluation of efficacy is binary restenosis.

The tertiary objective will be to assess the effect of rosiglitazone on major cardiac events (MACE; death, MI, CABG, and target vessel revascularization). The occurrence of in-stent restenosis for patients with metabolic syndrome who receive a DES in a non-target lesion will be assessed angiographically at 9 months.

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.

Detailed Description

This is a prospective, multicenter, double blind, randomized clinical trial of patients who present to the catheterization laboratory for PCI (elective or setting of ACS) and receive at least one bare metal stent.

Patients will be randomized on a 1:1 basis to receive either rosiglitazone or placebo for 9 months. Patients will be followed for 9 months post procedure. All patients will be required to have a repeat angiogram with optional IVUS analysis at 9 months.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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
The primary objective is to assess the efficacy of rosiglitazone on bare metal stent (BMS) in-stent restenosis measured as late lumen loss in patients with metabolic syndrome.

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
The secondary parameter for evaluation of efficacy is binary restenosis.
The tertiary objective is to assess the effect of rosiglitazone on major cardiac events and target vessel revascularization).
