NCT ID NCT06700239

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a new device called the MIA-T system, which is inserted through a catheter to repair the tricuspid valve in people with severe leakage. The trial will enroll 600 patients who are too high-risk for traditional surgery. The goal is to see if the device safely improves symptoms, reduces hospitalizations, and lowers the risk of death.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
MIA-T device (a catheter-based implant to repair the tricuspid valve)
What this could lead to
If successful, this could offer a safer, less invasive option for people with severe tricuspid regurgitation who cannot have open-heart surgery, potentially reducing hospitalizations and improving survival.
What could go wrong
This is a large but early-stage pivotal trial; the device may not work as well as hoped, and risks include heart-related complications, kidney failure, or infection. Long-term benefits are not yet proven.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 600 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Dec 2025

An estimate. Start dates often move.

Expected to finish

Dec 2032

An estimate. End dates often move.

Lead sponsor

A company

The lead sponsor is a pharmaceutical, biotech, or medical-device company.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Subject has severe functional TR (≥ 3). Note: If any cardiac procedure(s) occur after eligibility was determined, TR severity will need to be re-assessed 30 days after any cardiac procedure(s) * In the judgment of the site's local heart team patient is at intermediate or greater risk for morbidity \& mortality with tricuspid valve surgery, and has been adequately treated per applicable standards with optimized medical therapy for the treatment of TR (e.g. diuretics) and stable for at least 30 days prior to enrollment. * New York Heart Association (NYHA) Functional Class II, III or ambulatory class IV Exclusion Criteria: * Systolic pulmonary artery pressure (sPAP) \> 70 mmHg or \> 5 wood units (WU) despite vasodilator therapy * Severe uncontrolled hypertension Systolic Blood Pressure (SBP) ≥ 180 mmHg and/or Diastolic Blood Pressure (DBP) ≥ 110 mm Hg * Previous tricuspid valve repair or replacement (transcatheter or surgical approach) * Subjects with concomitant left-sided valve disease will have the option of receiving a left-sided intervention (e.g. TMVR or TAVR) and waiting 60 days prior to being reassessed for the study * Myocardial infarction (MI), known unstable angina, symptomatic coronary artery disease (CAD) where revascularization is possible within 60 days prior to enrollment * Anatomy that precludes safe placement of anchors around the annulus * Hemodynamic instability defined as systolic pressure \< 90 mmHg requiring pressor support within the last 30 days Echo Criteria - * Subject has severe functional TR (determined by the ICL). Note: If any cardiac procedure(s) occur after eligibility was determined, TR severity will need to be re-assessed 30 days after any cardiac procedure(s) * No presence of Cardiac Implantable Electronic Devices (CIED) leads causing the TR * No significant annular calcification * Left Ventricular Ejection Fraction (LVEF) ≥ 20%
