About this study

Official title: Immediate Myocardial Metabolic Enhancement During Initial Assessment and Treatment in Emergency Care Trial

The purpose of this study is to test the impact of pharmacological myocardial metabolic support, in the form of intravenous (IV) glucose, insulin and potassium (GIK), for the treatment of patients with threatened or established acute myocardial infarction (AMI).

Read the detailed description

BACKGROUND:

Basic and clinical research suggests intravenous GIK metabolic myocardial support reduces ischemia-induced arrhythmias, progression from unstable angina pectoris (UAP) to acute myocardial infarction (AMI), myocardial infarction (MI) size, and mortality. Also, for ST elevation MI (STEMI), GIK may prolong time of benefit of coronary reperfusion. These effects should reduce short- and long-term mortality from ACS, including AMI and UAP, and the propensity for heart failure (HF). These benefits are related to the earliness of ACS, when both risk and opportunity to save lives are highest.

DESIGN NARRATIVE:

This is a randomized, placebo-controlled, double-blinded, multicenter clinical trial of IMMEDIATE GIK as early as possible in ACS in the prehospital emergency medical service (EMS) setting. Distinct from prior and ongoing GIK trials, this will test GIK for all ACS rather than only for AMI or STEMI in prehospital EMS. The primary hypothesis is that early GIK will prevent or reduce the size of acute myocardial infarction. Major secondary hypotheses posit GIK will reduce mortality (30 days and 1 year), reduce pre- or in-hospital cardiac arrest and the propensity for heart failure. Other hypotheses address mechanisms of these effects.

What is being measured

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

  1. Progression of Acute Coronary Syndrome to Myocardial Infarction

    Outcome for all participants during the first 24 hours of hospitalization; evidence of myocardial infarction is determined by ECG and biomarker results.

    Measured: 24 hours

Secondary outcomes (4)

  1. Cardiac Arrest

    Outcome for all participants who had a cardiac arrest from initial contact in the prehospital setting through their subsequent hospitalization.

    Measured: 1 to 18 hours (From prehospital setting through hospitalization.)

  2. Heart Failure or Death

    Outcome for all participants (composite of re-hospitalization for heart failure or death within 30 days)

    Measured: 30 days

  3. Mortality

    Outcome for all participants (mortality at 30 days).

    Measured: 30 days

  4. Cardiac Arrest or Acute Mortality

    Outcome for all participants (composite of cardiac arrest or acute mortality)

    Measured: Prehospital setting through hospitalization

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing GIK in people with Angina, Unstable and Cardiovascular Diseases, run by Tufts Medical Center at 13 sites in United States.

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 5 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 2 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States. 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 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?

Yes. Results are posted in the registry (first posted 30 Jan 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Progression of Acute Coronary Syndrome to Myocardial Infarction (time frame: 24 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 NCT00091507, which also lists 10 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 2 Mar 2016.
