About this study
Official title: Exenatide for Myocardial Protection During Reperfusion Study: A Double-blind, Placebo-controlled Trial
This study aims to assess the effect of exenatide on myocardial injury in patients undergoing emergent percutaneous coronary intervention (PCI) for ST segment elevation myocardial infarction or heart attack (STEMI).
Read the detailed description
This is a Phase II randomized, double-blind, placebo-controlled study of patients with STEMI. Those who agree to participate will be immediately randomized to one of two groups: a 24-h infusion of exenatide; or a 24 h infusion of placebo. We will assess the ability of exenatide to reduce ischemic injury. This study will serve as safety evaluation study as well as a pilot for a larger multicentre trial powered for clinical outcomes.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ExenatideDrug
Also called Byetta
Intravenous bolus and 24-hour infusion of exenatide
PlaceboDrug
Intravenous bolus and 24-hour infusion of placebo
| Study group | Role | What they receive |
|---|---|---|
| Exenatide | Experimental | o Exenatide at a dose of 1.5 µg IV over 30 min followed by 1.2 µg/hr IV for 1.5 h (Rate1), followed by 1.9 µg/hr IV* for 22 h (Rate 2)
*Once the creatinine clearance is available, if the value is <60 mL/min, the rate at 2 hours will be maintained at Rate 1 for the duration of the infusion. If the value becomes available after the 2-hour point, and the rate has already been changed to Rate 2, the infusion will be titrated back down to Rate 1 if the creatinine clearance is <60 mL/min.
If the creatinine clearance is <30 mL/min, the infusion will be discontinued and the patient will otherwise continue with all study procedures.
A bolus administration of study medication is initiated preferably prior to reperfusion, or, if not possible, up to 30 minutes after the start of reperfusion to avoid delays in door-to-door balloon times. Receives: Drug: Exenatide |
| Placebo | Placebo comparator | o Placebo bolus over 30 min followed by placebo infusion at 'Rate 1' for 1.5 h, followed by 'Rate 2' for 22 hours*. Receives: Drug: Placebo |

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Exenatide in people with Myocardial Infarction, run by University Health Network, Toronto at 10 sites in Canada.
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 16 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: status not confirmed, as of the sponsor's last update on 5 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 10 sites in Canada. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Val Panzov, MD (416-864-6060 ext. 7125, panzovV@smh.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Ratio of final infarct size at 3 months over area at risk at 72 hours post randomization (using cMRI) (time frame: 3 months). 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 5 Aug 2016.
