About this study

Official title: Randomized, Double-blind, Parallel-group, Placebo-controlled Study of Melatonin as an Adjunct in Patients With Acute myocaRdial Infarction Undergoing Primary Angioplasty

Background: Experimental studies have documented the beneficial effects of the endogenously produced antioxidant, melatonin, in reducing tissue damage and limiting cardiac pathophysiology in models of experimental ischemia-reperfusion. Melatonin confers cardioprotection against ischemia-reperfusion injury most likely through its direct free radical scavenging activities and its indirect actions in stimulating antioxidant enzymes. These actions of melatonin permit it to reduce molecular damage and limit infarct size in experimental models of transient ischemia and subsequent reperfusion.

Study design: The Melatonin Adjunct in the acute myocaRdial Infarction treated with Angioplasty (MARIA) trial is a prospective, randomized, double-blind, placebo-controlled, phase 2 study of the intravenous administration of melatonin. The primary efficacy end point of this study is to determine whether melatonin treatment reduces infarct size determined by cardiac magnetic resonance 5-7 days post-reperfusion. Other secondary end points will be the clinical events occurring within the first year: death, sustained ventricular arrhythmias, resuscitation from cardiac arrest, cardiogenic shock, heart failure, major bleedings , stroke, need for revascularization, recurrent ischemia, re-infarctions and rehospitalization; and changes in left ventricular ejection fraction from baseline to 4 months of follow-up.

Implications: The MARIA trial tests a novel pharmacologic agent, melatonin, in patients with acute myocardial infarction and the hypothesis that it will confer cardioprotection against ischemia-reperfusion injury. If successful, the finding would support the use of melatonin in therapy of ischemic-reperfusion injury of the heart.

What participants receive

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

  • melatoninDrug

    Also called 5-methoxy-tryptamine

    Patients will receive a total intravenous melatonin dose of 12 mg + intracoronary melatonin dose of 2 mg. The intravenous dose will be distributed in a volume of 50 ml of a isotonic and sterile solution and administered by intravenous infusion during 60 minutes. The intracoronary dose will be distributed in a volume of 10 ml of a isotonic and sterile solution and administered as a bolus.

What is being measured

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

  1. Infarct size

    The primary efficacy end point in this study is to determine whether melatonin treatment reduces infarct size (percentage of total myocardial necrotic mass) by cardiac magnetic resonance

    Measured: 5-7 days post-reperfusion

Secondary outcomes (2)
  1. Major cardiac events: Death, sustained ventricular arrhythmias, resuscitation from cardiac arrest, cardiogenic shock, heart failure, major bleedings, stroke, need for revascularization, recurrent ischemia, re-infarctions and re-hospitalization.

    Measured: within the first year

  2. Changes in left ventricular ejection fraction evaluated by cardiac magnetic resonance

    Measured: 4 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing melatonin in people with Acute Myocardial Infarction, run by Alberto Domínguez Rodríguez at 3 sites in Spain.

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 11 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 22 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Spain. 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?

The study was stopped early. 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?

Infarct size (time frame: 5-7 days post-reperfusion). 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 NCT00640094, 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 22 Jul 2020.
