About this study

Official title: Nesiritide Therapy for the Preservation of Left Ventricular Function Post Anterior Myocardial Infarction

The purpose of this study is to determine the efficacy of intravenous human beta natriuretic peptide (BNP, Nesiritide) as compared to placebo to prevent adverse post acute myocardial infarction left ventricular remodeling.

Read the detailed description

Post acute myocardial infarction (AMI) left ventricular (LV) remodeling begins within hours of the acute event with permanent consequences. Previous studies have demonstrated that LV remodeling is one of the major determinants of long-term survival post AMI. Recent studies have reported that the cardiac natriuretic peptides, atrial natriuretic peptide (ANP) and BNP have direct anti-fibrotic and anti-proliferative effects on the myocardium. More importantly, it has been reported that in the acute phase of AMI, the secretion of the cardiac natriuretic peptides may be insufficient relative to the chronic phase. Therefore, augmentation of the cardiac natriuretic peptide system, such as by exogenous administration of exogenous peptide may prevent post AMI LV remodeling because of the cardioprotective effects. The objective of this study is to to determine the efficacy of IV human BNP (Nesiritide) as compared to placebo to prevent adverse post AMI LV remodeling. This is a randomized double blinded placebo controlled study to determine efficacy of 72 hours of IV BNP at 0.006µg/Kg/min as compared to placebo in patients with anterior ST-elevation myocardial infarction and successful revascularization. The study population will include 60 patients admitted to the Cardiac Care Unit with a first anterior AMI and successful reperfusion therapy (TIMI grade 3 flow) within 24 hours of onset of chest pain documented by coronary angiography.

What is being measured

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

  1. Change in Left Ventricular End-Systolic Volume Index

    Change in Left Ventricular end-systolic volume index as determined by Multiple Gated Acquisition (MUGA) scan from baseline to 30 days. The MUGA scan is a noninvasive tool for assessing the function of the heart. The MUGA scan produces a moving image of the beating heart, and from this image several important features can be determined about the health of the cardiac ventricles (the heart's major pumping chambers). End-systolic volume (ESV) is the volume of blood in a ventricle at the end of contraction, or systole, and the beginning of filling, or diastole. ESV is the lowest volume of blood in the ventricle at any point in the cardiac cycle and can be used clinically as a measurement of the adequacy of cardiac emptying, related to systolic function.

    Measured: baseline, 30 days

Secondary outcomes (2)
  1. Change in Left Ventricular End-Systolic Diastolic Volume Index

    Change in Left Ventricular end-systolic diastolic volume index determined by Multiple Gated Acquisition (MUGA) scan from baseline to 30 days. The MUGA scan is a noninvasive tool for assessing the function of the heart. The MUGA scan produces a moving image of the beating heart, and from this image several important features can be determined about the health of the cardiac ventricles (the heart's major pumping chambers). End-systolic volume (ESV) is the volume of blood in a ventricle at the end of contraction, or systole, and the beginning of filling, or diastole. ESV is the lowest volume of blood in the ventricle at any point in the cardiac cycle and can be used clinically as a measurement of the adequacy of cardiac emptying, related to systolic function.

    Measured: baseline, 30 days

  2. Myocardial Infarct Size at 30 Days

    Myocardial infarction or acute myocardial infarction (AMI) is the medical term for an event commonly known as a heart attack. Myocardial (heart muscle) infarction is tissue death (also known as necrosis) caused by a local lack of oxygen, due to an obstruction of the tissue's blood supply. The resulting heart tissue lesion is referred to as an infarct. A larger size or area of infarct indicates a greater amount of heart tissue death. Myocardial infarct size was measured using a cardiac Magnetic Resonance Imaging (MRI) scan at 30 days and is the mass of the infarcted tissue divided by the mass of the left ventricle times 100%.

    Measured: 30 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Nesiritide in people with Acute Myocardial Infarction, run by Mayo Clinic at 2 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 1 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: finished, as of the sponsor's last update on 9 Sep 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 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?

Yes. Results are posted in the registry (first posted 9 Sep 2014). 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?

Change in Left Ventricular End-Systolic Volume Index (time frame: baseline, 30 days). 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 NCT00573144, 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 9 Sep 2014.
