About this study

Official title: Clinical Investigation of the Caisson Transcatheter Mitral Valve Replacement (TMVR) System for Percutaneous Mitral Valve Replacement in Patients With Symptomatic Mitral Regurgitation

The purpose of this study is to assess the safety and performance of Transcatheter Mitral Valve Replacement (TMVR) system for the treatment of severe, symptomatic mitral regurgitation (MR).

Read the detailed description

The treatment guidelines for valvular heart disease indicate that surgical correction of primary mitral valve regurgitation (MR) is a Class I recommendation. Recent evidence indicates that valve replacement is at least as effective as repair in both primary and secondary MR patients. However, many patients are not referred for surgery as they are considered to be too high of a risk to undergo on-pump, open-heart procedures. Percutaneous aortic valve replacement has made treatment of stenosed aortic valves available to high-risk surgical patients who would have otherwise been medically managed. Percutaneous mitral valve (MV) replacement offers similar advantages. The feasibility of percutaneous MV replacement has been demonstrated in early feasibility studies. To meet this medical need, Caisson Interventional has developed a percutaneous delivery system for a bioprosthetic mitral valve. As with patients with aortic valve (AV) deficiencies, this device can be used to provide needed therapy to patients who might not otherwise receive treatment beyond medical therapy. This study will provide information on the safety and performance of this system.

What is being measured

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

  1. Number of patients without Major Adverse Events (MAEs)

    Freedom from major adverse events including death, stroke, myocardial infarction and surgical reintervention through 30 days

    Measured: 30 days

Secondary outcomes (2)
  1. Number of patients with successful delivery and implantation of the prosthetic valve (technical success)

    Successful delivery and retrieval of the transcatheter mitral valve delivery system; deployment and correct positioning (via intraoperative imaging) in the appropriate anatomic location of prosthetic valve with no requirement for additional surgery

    Measured: Intra-operative

  2. Number of living, stroke-free patients with prosthetic valve in place (device success)

    Patient is alive, stroke-free, original intended device in place (echo), no mitral valve surgical re-intervention required

    Measured: 30 days

Questions about this trial

What is this clinical trial studying?

A study testing Transcatheter Mitral Valve Replacement in people with Mitral Regurgitation and Mitral Valve Disease, run by Caisson Interventional LLC at 1 site 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 3 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 28 Jan 2020. 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 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. 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?

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?

Number of patients without Major Adverse Events (MAEs) (time frame: 30 days). 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 28 Jan 2020.
