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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested a new, noninvasive technique called magnetogastrogram (MGG) to measure the stomach's electrical activity without radiation. Researchers studied 22 people, including those with diabetes, gastroparesis, and other stomach conditions, to see if the test can tell normal from abnormal stomach function. The goal is to develop a safe, repeatable diagnostic tool for common stomach disorders.

What this could mean

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

What this could lead to
If successful, this could lead to a simple, radiation-free test to diagnose stomach problems like gastroparesis and chronic nausea.
What could go wrong
This is a very early, small study (22 people) focused on measuring electrical activity, not treating disease. The test may not prove accurate enough for routine use.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Participants between ages 12-80 * Diabetic patients with gastroparesis, diabetic patients without gastroparesis and who are willing to have a gastric emptying test if they have not had one in the last 6 months and an IV inserted. * Patients with idiopathic gastroparesis * Total or partial gastrectomy patients * Children (ages 12-17) with functional dyspepsia * Children (ages 12-17) with chronic nausea Exclusion Criteria: * Those with claustrophobia who cannot lie still under the SQUID for the length of time required. * Normal participants with known intestinal complications * Pregnant females (females who are able to have children will be given a pregnancy test). * Morbid obesity (these patients are presumably unable to lie under the current generation of SQUID devices). * Patients with a history of cardiac arrhythmias, taking anticoagulants, or greater than 80 years of age will be excluded.
