Clinical Study to Evaluate the Safety and Effectiveness of MER® Stents in Carotid Revascularisation. (MER)

November 18, 2019 updated by: Balton Sp.zo.o.

Badanie Kliniczne oceniające bezpieczeństwo i skuteczność Stosowania stentów Szyjnych MER® w Rewaskularyzacji tętnic Szyjnych.

The aim of the study is to confirm, whether the MER® stent can be used, without limitations, for the endovascular carotid stenosis treatment in daily clinical practice. Eligible patients will undergo the procedure of the common or internal carotid artery stenting using MER® with proximal or distal neuroprotection.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

MER® stent will be implanted in eligible patients with common and internal carotid stenosis after an informed consent.

Potential benefit of the MER® stent implantation will be evaluated based on angiography and duplex Doppler ultrasound examination.

Follow ups are scheduled at 30 days, 6 and 12 months after index procedure. Except for clinical follow up patients will undergo carotid vessels ultrasound examination after 6 and 12 months. In case of an emergency visit, caused by the Serious Adverse Event, Patient will undergo: neurological and cardiac evaluation as well as carotid vessels USG examination and extended CT or MRI scans.

In general, all procedures in the study will follow the local standard of care. The type of devices used during the angioplasty (including the MER® stents) will not differ from the devices used in the usual clinical practice in the hospital. DAPT and other medical therapy will be consistent with the rules of the Polish and European Society of Cardiology.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
