About this study

Official title: A Randomized, Multicenter, Double-Blind, Study to Evaluate the Efficacy of Tirofiban HCl Versus Placebo in the Setting of Standard Therapies Among Subjects Undergoing Percutaneous Coronary Intervention

The purpose of this study is to determine whether the efficacy of tirofiban (a 25mcg/kg i.v. bolus followed by a 0.15mcg/kg/min i.v. infusion during a percutaneous coronary intervention (PCI) plus two hours after the procedure) is more effective than placebo in the setting of standard therapies (e.g. aspirin, a thienopyridine, and unfractionated heparin or bivalirudin) among patients undergoing PCI, as assessed by the incidence of adverse cardiac ischemic events defined as death, myocardial infarction (MI), and urgent target vessel revascularization (uTVR) within 48 hours following study drug initiation.

A secondary objective of this study is to assess whether tirofiban (a 25mcg/kg i.v. bolus followed by a 0.15mcg/kg/min i.v. infusion during a PCI plus two hours after the procedure) is safe compared to placebo in the setting of standard therapies (e.g. aspirin, a thienopyridine, and unfractionated heparin or bivalirudin) among patients undergoing PCI, as assessed by the incidence of non-CABG-related TIMI major bleeding within 48 hours following study drug initiation.

Patient enrollment is pending.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Tirofiban (Aggrastat)Drug

    Tirofiban (Aggrastat) will be dosed as a 25mcg/kg i.v. bolus followed by a 0.15mcg/kg/min i.v. infusion during a percutaneous coronary intervention plus two hours after the procedure.

    Patients will receive tirofiban (Aggrastat) on a background of oral anti-platelet agent(s) and either unfractionated heparin (50U/kg and repeat dosing guided per guidelines) or bivalirudin as per local practice and physician discretion.

  • PlaceboDrug

    Placebo will be dosed as an i.v. bolus followed by an i.v. infusion during a percutaneous coronary intervention plus two hours after the procedure.

    Patients will receive placebo on a background of oral anti-platelet agent(s) and either unfractionated heparin (50U/kg and repeat dosing guided per guidelines) or bivalirudin as per local practice and physician discretion.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Tirofiban (Aggrastat) in people with Myocardial Infarction and Acute Coronary Syndromes, run by Medicure.

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 3 inclusion and 6 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: withdrawn, as of the sponsor's last update on 13 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.

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 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 withdrawn before enrolling participants, so there are no results.

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?

A composite incidence of death, myocardial infarction and urgent target vessel revascularization. (time frame: 48 hours). 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 NCT01245725, which also lists 6 linked publications.

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 13 Mar 2018.
