Evaluation of Safety and Efficacy of the BACE™ Device in the Treatment of Functional Mitral Valve Regurgitation [FMR (BACE)

September 14, 2020 updated by: Phoenix Cardiac Devices, Inc.

Evaluation of Safety and Efficacy of the Basal Annuloplasty of the Cardia Externally (BACE™) [Basal Annuloplasty of the Cardia Externally] Device in the Treatment of Functional Mitral Valve Regurgitation [FMR]

The preclinical and clinical evidence of safety and efficacy with the BACE device (concept and feasibility) paved the way for the evaluation of the BACE device in this prospective, multi-center, single-arm, self-controlled study for safety and efficacy in the treatment of functional MR in a maximum of 60 adult subjects.

The primary efficacy endpoint will be reduction of MR grade to 1+ or less from the baseline MR grade through the 6 month study period. Primary safety endpoint will be freedom from major device and surgery-related adverse events for the duration of the 6 month follow up period. Patients will be followed up to two years.

Study Overview

Status

Status

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

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

The primary objective of this study is to assess the safety and efficacy of the BACE device for the treatment of FMR.

Secondary objective is to assess the ease of deployment of the BACE device Study Population: Since this study is to assess the safety and efficacy of a new device, with no control arm or comparator, the number of subjects enrolled will be a maximum of 60.

Approximately 8-10 sites are expected to be included in the study. The subject population is adults of 18 to 80 years of age, either gender, with FMR as specified in the inclusion and exclusion criteria.

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

14 years to 76 years (Adult, Older Adult)
