August 6, 2012 updated by: Seung-Jung Park

Comparison Between Drug-Eluting Stents for the Treatment of the Diffuse Type In-Stent Restenosis After Drug-Eluting Stents Implantation: Sirolimus-Eluting vs. Paclitaxel-Eluting Stents

To evaluate the best therapeutic option for the treatment of diffuse type post-drug-eluting stent restenosis.

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

Despite a significant reduction of angiographic restenosis and the need for repeat revascularization after introduction of DES, post-DES restenosis still occur and the treatment for DES failure is challenging. However, there have been little data for therapeutic strategy for post-DES restenosis, especially diffuse type ISR. Therefore, we need the well-designed randomized trial to achieve the best therapeutic option for the treatment of diffuse type post-DES restenosis.

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

Inclusion Criteria:

  2. Restenosis after drug-eluting stents (>50% by visual estimate)
  3. Lesion length ≥ 10 mm (diffuse type ISR)
  4. Patients with stable (CCS class 1 to 4) or acute coronary syndromes (unstable angina pectoris Braunwald class IB, IC, IIB, IIC, IIIB, IIIC or NSTEMI) or patients with atypical chest pain or without symptoms but having documented myocardial ischemia, amenable to stent-assisted percutaneous coronary intervention

    • Heparin
    • Aspirin
    • Both Clopidogrel and TIclopidine
    • Sirolimus eluting stent
    • Stainless steel and/or
    • Contrast media (patients with documented sensitivity to contrast which can be effectively pre-medicated with steroids and diphenhydramine [e.g. rash] may be enrolled. Patients with true anaphylaxis to prior contrast media, however, should not be enrolled).
  2. Systemic (intravenous) Sirolimus use within 12 months.
  3. Female of childbearing potential, unless a recent pregnancy test is negative, who possibly plan to become pregnant any time after enrollment into this study.
  4. History of bleeding diathesis or known coagulopathy (including heparin-induced thrombocytopenia), or will refuse blood transfusions.

  7. Non-cardiac co-morbid conditions are present with life expectancy <1 year or that may result in protocol non-compliance (per site investigator's medical judgment).
  8. Patients who are actively participating in another drug or device investigational study, which have not completed the primary endpoint follow-up period.
  9. Patients with EF<30%.
  10. Acute MI patients within symptom onset < 12 hours needing primary angioplasty
