February 11, 2014 updated by: Seung-Jea Tahk, Ajou University School of Medicine

Fractional Flow Reserve- And Intra-vascular Ultrasound-Guided Percutaneous Coronary Intervention With Drug-Eluting Stents in Intermediate Coronary Artery Lesion (FAVOR Study)

This study is a prospective, randomized, multi-center, open label trial to compare the clinical outcomes and effectiveness of Intravascular ultrasound (IVUS) versus Fractional Flow Reserve (FFR) guided Percutaneous coronary intervention (PCI) with intermediate coronary artery lesion.

Study Overview

Status

Status

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

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 trial is a prospective, randomized, open label, two arm designed multi-center trial. When diagnostic coronary angiogram shows that the target lesion is intermediate stenosis, IVUS and/or FFR will be performed in order to decide PCI or defer by 1:1 randomization. The patients would be followed up to 2 years clinically.

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.

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.
