The purpose of this study is to determine whether acadesine is effective in reducing the cardiovascular and cerebrovascular adverse events in high-risk participants undergoing CABG surgery.

Being tested
Acadesine, Normal Saline
Medical subject headings
Myocardial Infarction, Ventricular Dysfunction, Left, Stroke

What participants receive

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

  • AcadesineDrug

    Also called SCH 900395

    Acadesine 42 mg/kg diluted in normal saline to a total of 500 mL, delivered as an IV infusion over approximately 7 hours commencing within approximately 30 minutes before induction of anesthesia at a rate of 0.1 mg/kg/min (translating into 1.2 mL/min for a 500 mL solution). In addition, a 5 µg/mL cardioplegia solution of acadesine will be administered, and acadesine will be added to the priming solution (5 µg/mL) in the heart lung machine during CPB.

  • Normal SalineDrug

    Normal saline, 500 mL delivered as an IV infusion over approximately 7 hours commencing within approximately 30 minutes before induction of anesthesia at a rate of 1.2 mL/min for a 500 mL solution. In addition, standard cardioplegia solution with added normal saline will be administered, and placebo (normal saline) will also be added to the heart lung machine priming solution.

What is being measured

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

  1. Incidence of All-cause Death, Non-fatal Stroke, and Need for Mechanical Support for Severe Left Ventricular Dysfunction (SLVD) (Intent-to-Treat Population)

    Incidence of all-cause death, non-fatal stroke, or need for mechanical support for SLVD (any component and composite) through post-operative Day 28 during and following CABG and administration of acadesine or placebo. Components defined as follows: All-cause death: Death from any cause, Non-fatal Stoke: occurrence of a stoke that was confirmed and adjudicated by Clinical Endpoints Committee that did not result in death, and Mechanical Support for SLVD: New use of any mechanical support for ≥1 hour for treatment of low cardiac output.

    Measured: Up to Post-Operative Day 28

Secondary outcomes (1)
  1. Incidence of Cardiovascular Death, Non-fatal Stroke, and Need for Mechanical Support for SLVD (Intent-to-Treat Population)

    Incidence of cardiovascular death, non-fatal stroke, and need for mechanical support for SLVD (any component and composite) through post-operative Day 28 during and following CABG and administration of acadesine or placebo. Components defined as follows: Cardiovascular death: Death due to cardiovascular causes, Non-fatal Stroke: occurrence of a stroke that was confirmed and adjudicated by Clinical Endpoints Committee that did not result in death, and Mechanical Support for SLVD: New use of any mechanical support for ≥1 hour for treatment of low cardiac output.

    Measured: Up to Post-Operative Day 28

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Acadesine and Normal Saline in people with Coronary Artery Bypass and Myocardial Infarction, run by Merck Sharp & Dohme LLC.

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 10 inclusion and 13 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 29 Oct 2015. 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?

Yes. Results are posted in the registry (first posted 20 Dec 2012). 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?

Incidence of All-cause Death, Non-fatal Stroke, and Need for Mechanical Support for Severe Left Ventricular Dysfunction (SLVD) (Intent-to-Treat Population) (time frame: Up to Post-Operative Day 28). 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 NCT00872001, which also lists 2 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 29 Oct 2015.
