FIH ITA Study - Vesalius TMVr System for Symptomatic Degenerative Mitral Regurgitation

August 17, 2026 updated by: Vesalius Cardiovascular Inc.

A First-in-Human Investigational Testing Authorization Study Evaluating the Safety and Performance of the Vesalius Transcatheter Mitral Valve Repair System in Patients With Severe, Symptomatic Degenerative Mitral Regurgitation

This first-in-human study evaluates the safety and performance of the Vesalius Transcatheter Mitral Valve Repair (TMVr) System in patients with degenerative mitral regurgitation. The study will enroll patients who are at high or prohibitive risk for conventional surgical repair or replacement of the mitral valve. Participants will receive implantation of the Vesalius TMVr System and will be followed to assess clinical outcomes, device performance, and any adverse events.

Detailed Description

This first-in-human study is designed to evaluate the safety and performance of the Vesalius Transcatheter Mitral Valve Repair (TMVr) System in patients with symptomatic, severe or moderate-to-severe degenerative mitral regurgitation who are at elevated surgical risk. The study will enroll up to five patients in Canada to assess procedural feasibility, technical performance, and short-term clinical outcomes following device implantation. Endpoints are based on Mitral Valve Academic Research Consortium (MVARC) definitions, including measures of procedural and device success, freedom from major adverse events, and technical achievement of device deployment. Safety, functional, and hemodynamic parameters will be monitored at predefined intervals, and follow-up will include assessment of valve function, adverse events, and device performance. This study will provide preliminary data to support the further development and evaluation of the Vesalius TMVr System.

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

  • Adult
  • Older Adult

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: Vesalius TMVr System
Participants in this arm will undergo implantation with the Vesalius Transcatheter Mitral Valve Repair (TMVr) System according to the study protocol. All procedures will be performed by trained interventional cardiologists, and participants will be followed for safety, device performance, and clinical outcomes at predefined intervals.
Device: Transcatheter Mitral Valve Repair
The Vesalius Transcatheter Mitral Valve Repair (TMVr) System is a novel transcatheter device designed to percutaneously deliver an implant to repair the native mitral valve in patients with degenerative mitral regurgitation. The system uses an adjustable ePTFE net to reduce or eliminate mitral regurgitation. The device is delivered via a minimally invasive transcatheter approach, allowing precise positioning and deployment in high-risk patients not suitable for conventional surgery.

Time Frame: 30 Days
Number of participants experiencing all-cause mortality post-implant, prior to discharge, and through the 30-day follow-up period.

Time Frame: Measured at Day 0 (Procedure Exit)
Number of participants achieving successful delivery and positioning of the device, absence of procedural mortality, and freedom from emergency cardiovascular surgery or reintervention related to the device through procedure exit.

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.
Outcome Measure
Measure Description
Time Frame
Number of Participants by Mitral Regurgitation (MR) Severity Grade
