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 Results may not be published yet.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

Summary

This study is testing a new method to measure how well the gallbladder contracts, using protein bars and olive oil instead of a fatty meal. Researchers will compare this to the standard fried-egg test in 120 healthy volunteers. The goal is to find the best time to take ultrasound measurements after eating, to make gallbladder function testing more reliable and consistent.

What this could mean

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

Active substance
oral protein bars + 50ml olive oil
What this could lead to
If successful, this could provide a simpler, standardized way to assess gallbladder function, potentially improving diagnosis of gallbladder disorders.
What could go wrong
This is an early-stage study in healthy volunteers, so results may not apply to people with gallbladder disease. The method may not be reliable or comfortable for all patients.

Expected to finish

Dec 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.
