About this study

Official title: A RANDOMIZED TRIAL COMPARING EPTIFIBATIDE AND PLACEBO IN PATIENTS WITH DIFFUSE CORONARY DISEASE UNDERGOING DRUG-ELUTING STENTING

Patients with stable coronary artery disease, undergoing PCI by means of implantation of >33 mm of DES, will be randomized single-blinded to eptifibatide plus unfractioned heparin according to the ESPRIT protocol vs placebo plus unfractioned heparin.

Read the detailed description

BACKGROUND: Despite the availability of several potent antithrombotic agents, the optimal antiplatelet regimen in elective patients undergoing complex percutaneous coronary interventions is still debated. Aim of the INtegrilin plus STenting to Avoid myocardial Necrosis Trial (INSTANT) will be to assess the safety and efficacy of routine usage of the glycoprotein IIb/IIIa inhibitor eptifibatide in subjects already treated with aspirin and clopidogrel, and undergoing implantation of at least 2 drug-eluting stents in the same lesion, thus identifying a clinically stable but anatomically complex patient subset.

DESIGN: This will be a single-blind, placebo-controlled multicenter randomized trial METHODS: Patients with stable coronary artery disease, undergoing percutaneous coronary intervention (PCI) by means of implantation of >33 mm of DES (eg with two 23-mm DES, or one 32-mm and one 12-mm DES), will be randomized, after administration of aspirin and clopidogrel (600 mg loading dose recommended), to eptifibatide and unfractioned heparin according to the ESPRIT protocol vs placebo and unfractioned heparin. Blood draws for CK-MB mass, total CK and cardiac troponin levels will be taken at baseline, 6 and 12 hours post-procedurally. Patients will be followed for clinical events by direct visit or phone contact up to 6 months. The primary end-point of the study will be the rate of abnormal post-PCI CK-MB mass values. Secondary end-points will be: the composite of cardiac death, non-fatal myocardial infarction (MI), urgent target vessel revascularization (TVR), and thrombotic bailout GpIIb/IIIa inhibitor therapy within 180 days, and in-hospital, 1-month and 6-month major adverse cardiovascular events (MACE), defined as the composite of cardiac death, non-fatal MI, or urgent TVR.

IMPLICATIONS: The INSTANT Study will test for the first time the beneficial impact of routine GpIIb/IIIa inhibition on top of double oral antiplatelet treatment in clinically stable yet anatomically complex patients undergoing DES-implantation. Results of this single-blind randomized trial will provide important insights to improve the management strategy of patients and outcomes in the current DES era.

What is being measured

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

  1. Abnormal CK-MB level post-PCI

    The primary end point will be the rate of elevated post-procedural peak CK-MB mass ratio values (ie above the upper limit of normal [ULN], eg 1.01*ULN, according to each participating hospital laboratory).

    Measured: 2 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Eptifibatide in people with Coronary Artery Disease, run by University of Turin, Italy at 1 site in Italy.

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 17 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: stopped early, as of the sponsor's last update on 19 Oct 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. 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. Some participants in this study may receive a placebo. 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 was stopped early (reason given: The study was stopped prematurely due to slow enrolment without code breaking.). Results are not available in the source record.

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?

Abnormal CK-MB level post-PCI (time frame: 2 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01454440, which also lists 1 linked publication.

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 19 Oct 2011.
