Trial summary

Background: Percutaneous coronary intervention (PCI) is a highly effective therapy for acute ST-elevation myocardial infarction (STEMI). Adjunctive therapy with glycoprotein (GP) IIb/IIIa inhibitor can result in increased patency and improved outcomes in STEMI patients, with thrombus, undergoing PCI. Read more about this study

About this study

Official title: IntraCoronary Abciximab With the ClearWay Catheter To Improve Outcomes With Lysis

Background: Percutaneous coronary intervention (PCI) is a highly effective therapy for acute ST-elevation myocardial infarction (STEMI). Adjunctive therapy with glycoprotein (GP) IIb/IIIa inhibitor can result in increased patency and improved outcomes in STEMI patients, with thrombus, undergoing PCI. The investigation of novel dosing and delivery strategies of this therapy may help to further improve outcomes.

Study design: Intracoronary Abciximab With Clearway Catheter trial is a randomized, open-label, multicenter, trial to evaluate the effect of an intracoronary (IC) bolus dose of abciximab delivered using the ClearWay™RX catheter versus an intravenous bolus (IV) of abciximab for STEMI with angiographically visible thrombus (Thrombus Grade > 2). All patients in both arms will receive intravenous abciximab infusion following the PCI for 12 hours per standard practice. A total of 150 patients will be randomized 1:1 to treatment of the culprit artery with IC abciximab (75 subjects) or IV abciximab (75 subjects) in addition to an infusion regimen of abciximab administered intravenously and initiated following PCI. The primary endpoint chosen to evaluate this hypothesis is infarct size as assessed on Cardiac Magnetic Resonance (CMR). Clinical outcomes will be assessed for each subject through hospital discharge and at 30 day follow-up.

Sample size: The number of patients included in this study was based on the estimation of the sample size needed to identify a statistically significant difference of the primary end-points between the two groups. The investigators estimated that 75 patients would be required in each study group to have a power of 80% to detect an absolute difference in the infarct size resolution of 15% with a two-sided alpha value of 0.05.

Conclusion: The purpose of this study is to demonstrate that an IC bolus of abciximab delivered with the ClearWay™RX catheter added to a post-PCI intravenous infusion regimen of abciximab will result in significant additional clot resolution in vivo when compared with an IV bolus of abciximab when added to a post PCI intravenous infusion regimen of abciximab. The primary endpoint chosen to evaluate this hypothesis is infarct size as assessed on CMR.

What is being measured

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

  1. Reduction in infarct size for the IC infusion group compared to the control as measured with cardiac MRI imaging

    Measured: 24 months

Secondary outcomes (1)
  1. Angiographic outcomes of lesion, flow, and myocardial perfusion using established and validated Quantitative Coronary Angiographic Methodology

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Intracoronary bolus wtih ClearWay™RX catheter and IV abciximab in people with Acute Myocardial Infarction, run by Gennaro Sardella at 2 sites 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 7 inclusion and 12 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 4 Jan 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 because the sample size was very difficult to achieve.). 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?

Reduction in infarct size for the IC infusion group compared to the control as measured with cardiac MRI imaging (time frame: 24 months). 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 NCT00894023, 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 4 Jan 2013.
