About this study

Official title: The Mesoglycan and Vascular Reactivity in the Metabolic Syndrome

The purpose of the study was to characterize the action of mesoglycan on vascular endothelium through the non-invasive assessment of vascular reactivity humeral artery by comparing effects of mesoglycan on Flow Mediated Dilatation (FMD) of the humeral artery between a group of patients with metabolic syndrome assuming placebo and a group of patient with metabolic syndrome assuming mesoglycan; firstly after administration of the drug/placebo intramuscularly, and then, in a study of medium-term after oral intake of drug/placebo. The selection of patients with metabolic syndrome is related to the fact that this syndrome is associated with alterations in endothelial function and a high incidence of cardiovascular events. So it is a condition that offers the opportunity to explore the hypothesis that the mesoglycan may have a favorable effect on early vascular alterations that precede clinical events.

Read the detailed description

The subjects were enrolled in a double blind randomized way, according to a 2: 1 ratio, to intramuscular treatment with mesoglycan or placebo. Patients performed the study of the Flow Mediated Dilation (FMD) according to the following scheme:

  • FMD baseline
  • FMD 2 hours after the administration of 2 vials of mesoglycan or placebo intramuscularly
  • FMD 6 hours after intramuscular administration.

Nextly, both patients treated with mesoglycan vials and placebo vials continued therapy for assuming mesoglycan or placebo, per os, bis in die, for 90 days. At the end of this period of oral therapy (mesoglycan or placebo in a 2: 1 ratio), all patients performed FMD again. The patients who were taking any specific therapy (eg antihypertensive drugs) the Placebo was administered in addition to their standard therapy.

The vascular reactivity evaluation adopted was the Flow Mediated Dilatation (FMD). After a period of fasting and rest for at least 6 hours, the study of FMD was performed using a high-resolution ultrasound system, equipped with a 7.5 Megahertz linear probe under ECG monitoring. After a rest period of at least 10 minutes on a bed in supine decubitus in an air-conditioned room, the sensor was placed on humeral artery, 3-5 cm above the elbow, and held the same position during the examination through an arm mechanically connected. They were performing a number of longitudinal sections and measured the internal diameter of the vessel, defined as the distance between the top edge of the echo produced by the interface between the lumen and the anterior wall of the vessel and the top edge of the echo produced by the interface between the lumen and the rear wall of the vessel. The inner diameter of the vessel was measured several times, on the R wave of the ECG, and a pc "software" calculated the average value. The flow rate was measured with the sample volume placed in the center of the vase with a 60 ° angle between the ultrasound beam and the longitudinal axis of the vessel. The post-ischemic vasodilation was induced using a sphygmomanometer placed on the forearm, distal to the elbow crease, kept inflated to 250 mmHg for 5 minutes. The flow rate, always with a correction angle of 60 °, was recorded immediately after the desufflation; the diameter of the brachial artery, it was measured several times after desufflation (for 60-90 seconds). Nextly, the FMD was calculated as the percentage difference between the maximum diameter of the post-ischemic reached and the mean diameter of the base of the vessel.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Flow Mediated Dilation and Mesoglycan in people with Metabolic Syndrome, run by Federico II University at 1 site in Italy.

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 6 inclusion and 9 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 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Improvement of FMD (time frame: 90 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 NCT02254850, which also lists 14 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 Oct 2014.
