About this study

The objective of this prospective, multi-center trial is to assess the effectiveness of the CARILLON Mitral Contour System in treating patients with moderate-to-severe atrial functional mitral regurgitation (aFMR)

Read the detailed description

The AFIRE Trial is a prospective, multi-center clinical trial.

The centers will utilize pre-screening of existing medical records to identify potentially eligible subjects. Once informed consent has been obtained, the subject will undergo baseline assessments, which include: Transthoracic echocardiography, transesophageal echocardiography, and functional assessments (Six-Minute Walk Test, NYHA, and Quality of Life Questionnaires). Following final eligibility determination, eligible subjects will under the index procedure to implant the Carillon device (includes coronary sinus venogram). Subject will be discharged following one-night in-hospital stay and discharge assessments.

Subjects who have the Carillon implant procedure attempted but were not successfully implanted (Non-Implanted subjects) will be followed through discharge or resolution of safety events, whichever is longer, and then discharged from the trial.

Implanted subjects will have follow-up assessments performed at 1 month, 6 months, and 12 months post index procedure. Follow-up assessments will include transthoracic echocardiography, Six-Minute Walk Test, and Quality of Life Questionnaires.

What participants receive

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

  • Carillon Mitral Contour SystemDevice

    Also called Carillon, Carillon Device, Carillon Implant

    Eligible subjects will be implanted with the Carillon Device, utilizing the Carillon Mitral Contour System. The device is a permanent implant in the coronary sinus/great cardiac vein, designed to cinch the mitral annulus. The implant procedure is minimally invasive, conducted via catheter placement.

What is being measured

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

  1. Change in mitral regurgitant volume (mL) associated with the Carillon device at 6 months post-implant, as compared to baseline

    Measured: 6 Months

Questions about this trial

What is this clinical trial studying?

A study testing Carillon Mitral Contour System in people with Functional Mitral Regurgitation and Atrial Fibrillation, run by Cardiac Dimensions Pty Ltd at 2 sites in 2 countries.

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 9 inclusion and 31 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 17 Mar 2023. 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 Australia, Greece. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: The study was not accruing subjects as expected, due to limits in hospital resources and staff as a result of the COVID pandemic in Europe.). 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?

Change in mitral regurgitant volume (mL) associated with the Carillon device at 6 months post-implant, as compared to baseline (time frame: 6 Months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 17 Mar 2023.
