Periodontal Intervention for Cardiac Events: A Pilot Trial

The purpose of this study is to determine if treating periodontal infections (gum problems) will lead to fewer heart problems in patients at high risk for cardiovascular disease.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

There is growing evidence of a strong association between infection and atherosclerosis as well as a specific link between periodontal infection (gum problems) and heart disease. Previous studies have established possible effective treatments of periodontal disease. These treatments may lead to fewer heart events in persons at high risk for cardiovascular disease. In contrast to previous heart disease studies, the primary treatment in this project is directed toward infectious agents at periodontal sites. This project is a pilot randomized clinical trial to test the feasibility of selecting and refining a periodontal infection treatment and examining the effect of that treatment on future heart events. It is a multi-center planning and pilot study involving five investigational centers at the University at Buffalo (lead and overall coordinating center), University of North Carolina, Boston University, Kaiser Permanente/Oregon Health Science University, University of Maryland, and a data coordinating center at the University of North Carolina. Central microbiology and cytokine laboratories and a biologic specimen bank are also included. A team of cardiologists, periodontists, epidemiologists, infectious disease specialists, biostatisticians, research nurses in periodontics and cardiology, and data managers has been assembled to accomplish the research with a careful, cost-effective approach. The ultimate goal is to develop a definitive randomized clinical trial that will include about 4,000 participants from approximately 15 centers across the United States

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

No older than 75 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers
