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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 whether placing a lead apron on a patient's lower belly and pelvis during heart procedures can reduce radiation exposure for the doctor. The trial involves 500 adults undergoing heart catheterization through the wrist. Researchers will measure the doctor's radiation dose with and without the extra shielding to see if this simple, low-cost method improves safety.

What this could mean

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

Active substance
Patient-applied pelvic lead shielding (lead apron)
What this could lead to
If effective, this simple, low-cost method could become a standard practice to protect cardiologists from radiation during common heart procedures.
What could go wrong
This is a single-center trial testing a technique that may not reduce radiation as much as hoped, or may be impractical in real-world settings. Results may not apply to all hospitals or procedure types.

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 500 people

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

Started

Expected to finish

Jun 2026

An estimate. End dates often move.

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.
