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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 people with gastroparesis (slow stomach emptying) who have a gastric electrical stimulator (GES) implanted. Researchers will turn off the device for up to four hours to see how it changes insulin and other hormone levels. The goal is to understand the device's effect on the body, not to treat a condition. Participants must be at least 18, have had the device for three months, and not use insulin for diabetes.

What this could mean

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

Active substance
Gastric Electrical Stimulator (device)
What this could lead to
If successful, this could clarify how gastric stimulation affects insulin and blood sugar, potentially guiding future treatments for gastroparesis.
What could go wrong
This is a small, early observational study with only 32 participants, so results may not apply widely. It does not test a new treatment or cure.

This is an AI summary of the original study and may miss details. Read our disclaimer.
