Show all 19Show fewer
  • 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).
  • Systemic (intravenous) Sirolimus use within 12 months.

  • Current known current platelet count <100,000 cells/mm3 or Hgb <10 g/dL.
  • 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).
  • Patients who are actively participating in another drug or device investigational study, which have not completed the primary endpoint follow-up period.
  • Patients with EF<30%.
  • Acute MI patients within symptom onset < 12 hours needing primary angioplasty
  • Creatinine level 3.0mg/dL or dependence on dialysis.
  • Severe hepatic dysfunction (AST and ALT 3 times upper normal reference values).
  • Patients with left main stem stenosis and left main in-stent restenosis created by DES(>50% by visual estimate)

About this study

Official title: FOcal Type In-stent Restenosis After Drug-Eluting Stent Implantation Treated by CUtting Balloon Angioplasty Versus Sirolimus-Eluting Stent

To evaluate the optimal management of focal in-stent restenosis after drug-eluting stent implantation with sirolimus-eluting implantation versus cutting balloon angioplasty

Read the detailed description

Following angiography, patients with focal DES restenosis (lesion length ≤ 10mm) with diameter stenosis >50% by visual estimation have documented myocardial ischemia or symptoms of angina, and eligible for PCI without any exclusion criteria will be randomized 1:1 to: a) Cypher stent vs. b) Cutting balloon angioplasty. All patients will be followed for 1 year. Angiographic follow-up at 9-months is mandatory.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Binary In-segment Restenosis

    Measured: At 9 months angiographic follow-up

Secondary outcomes (4)
  1. Composite end-point of death, myocardial infarction, or target vessel revascularization

    Measured: At 9-month after index procedure

  2. Stent thrombosis

    Measured: In-hospital, 30 days, 9 months, and 1year

  3. Late luminal loss

    Measured: at 8 month angiographic follow-up

  4. Procedural success defined as achievement of a final diameter stenosis of <30% by QCA using any percutaneous method, without the occurrence of death, Q wave MI, or repeat revascularization of the target lesion

    Measured: during the hospital stay

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Cutting balloon and Sirolimus-eluting stent in people with In Stent Restenosis, run by Seung-Jung Park at 15 sites in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Aug 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Binary In-segment Restenosis (time frame: At 9 months angiographic follow-up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Aug 2012.
