New Generation Drug Eluting Stent for In-stent Restenosis of Drug Eluting Stent( RESTENT-ISR Trial ) (Restenosis)

June 2, 2011 updated by: Korea University Anam Hospital

Prospective, Single-blinded, Randomized Comparison of the Clinical and Angiographic Results With Intravascular Analysis of EverolimuS-Eluting Versus ZoTarolimus-Eluting steNTs for In-Stent Restenosis(ISR) Lesions: Volumetric Analysis With Intravascular Ultrasound(IVUS) : Phase IV Multicenter Trial ( RESTENT-ISR Trial )

The purpose of this study is to evaluate the feasibility, safety, and effectiveness of EndeavorTM ResoluteTM and Xience VTM stent implantation in patients with restenosis following drug-eluting stent (DES) implantation. The investigators will evaluate clinical, angiographic and intravascular ultrasound (IVUS) assessment of 9-month efficacy of EndeavorTM ResoluteTM or Xience VTM implantation in DES restenosis and assess the vascular changes of re-treatment with DES for DES restenosis using follow-up IVUS analysis. In addition, the investigators will evaluate the effectiveness of retreatment with EndeavorTM ResoluteTM or Xience VTM stent implantation in patients with restenosis after DES

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.

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

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.

Time Frame: 9 months on IVUS
9 months on IVUS

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
Measure Description
Time Frame
Major adverse cardiovascular events
