Epicardial Mitral Repair Trial - ENRAPT-MR (ENRAPT-MR)

January 17, 2023 updated by: Mitre Medical Corp.

ENRAPT-MR Trial: Epicardial Mitral Repair

Mitral Touch System

This device is designed to epicardially reshape the mitral valve annulus without the need for cardiopulmonary bypass (CPB) and open heart access (atriotomy), in patients with left ventricular dilation and ischemic or functional MR (mitral regurgitation (MR)).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

Mitre Medical has developed an epicardial mitral annuloplasty device that can be implanted concomitant during planned coronary artery bypass surgery to help treat the MR patients. The Mitral Touch is designed to restore the S-L dimension and has the advantage of being placed without stopping the heart and placing the patient on a bypass pump.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  • Patient is willing and able to sign informed consent form

Exclusion Criteria:

  • History of endocarditis or current endocarditis
  • Structural abnormalities of the leaflets and papillary muscles*
  • Dysfunctional chordae*

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Treatment
Treatment with the Mitral Touch Implant for Epicardial Annuloplasty.
Device: Mitral Touch Implant
The study population for this study will be comprised of patients who are to undergo cardiac surgery with a sternotomy (e.g. CABG) and who present moderate to severe ischemic or functional MR. In order to be considered eligible for the study, each patient must meet the conditions listed in the inclusion and none of the exclusion criteria.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety - 30 - Day Major Adverse Event Rate
Time Frame: 30-Days
30 - Day Major Adverse Event Rate All-cause mortality Stroke Life-threatening bleeding (MVARC scale) Major vascular complications Major cardiac structural complications Stage 2 or 3 acute kidney injury (includes new dialysis) Severe hypotension, worsening of heart failure, or respiratory failure requiring intravenous pressors or invasive or mechanical heart failure treatments such as ultrafiltration or hemodynamic assist devices, including intra-aortic balloon pumps or left ventricular or biventricular assist devices, or prolonged intubation for >48 h Emergency surgery or re-intervention related to the device or access procedure
30-Days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
