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
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 This study
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 Results may not be published yet.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.

Summary

This study tested two types of cameras—a newer CZT camera and a standard Anger camera—to see how well they measure heart nerve function in people with heart failure. Forty-five patients received a special tracer injection (I-123-MIBG) and were scanned with both cameras. The goal was to validate whether the newer camera gives equally reliable results, which could help doctors better assess heart failure severity.

What this could mean

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

Active substance
I-123-MIBG
What this could lead to
If successful, this could help doctors choose the best camera for evaluating heart failure patients, potentially improving risk assessment.
What could go wrong
This is a small, completed imaging comparison study, not a treatment trial. It does not test any new therapy or directly improve patient outcomes.

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

45 people

The number who actually took part.

Start date

Oct 2012

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

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

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.
