New study aims to spot heart transplant rejection without a biopsy

NCT ID NCT06774365

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at 683 heart transplant patients to see if advanced heart scans (CMR) and blood tests can detect antibody-mediated rejection, a common complication. Participants must be stable and at least one year post-transplant. The goal is to find non-invasive ways to diagnose rejection earlier and more accurately.

What this could mean

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

What this could lead to
If successful, this could lead to better, non-invasive ways to detect rejection in heart transplant patients, reducing the need for biopsies.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly improve outcomes. Results may not change current practices if imaging or biomarkers prove unreliable.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Clinically stable adult heart transplanted patients will be consecutively enrolled during the routinely outpatient evaluation in the participating centers after IRB approval. Heart Failure and Transplant Unit of IRCCS AOUBO will be the project leader and coordinate the overall study. The investigators plan a one year period for the enrollment and eight months for the follow-up. Patients will be treated and followed according to the routinary clinical practice of each participating center.
