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 Results may not be published yet.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

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.

Summary

This study tests a new PET scan technique to better track heart damage in people with a condition called ATTR-CM, a progressive heart muscle disease. Researchers will scan 140 participants to see if the imaging can show how well treatments are working. The goal is to improve monitoring and help doctors choose the best therapies for each patient.

What this could mean

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

Active substance
18F-fluoride PET scan (imaging tracer)
What this could lead to
If successful, this imaging technique could help doctors see how well treatments are working for ATTR-CM heart disease, leading to more personalized and cost-effective care.
What could go wrong
This is an early-stage imaging study, not a treatment trial. The new scan method may not prove accurate enough to replace current monitoring, and results may not apply to all patients.
