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 Results may not be published yet.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.

Summary

This study tests whether low-frequency magnetic stimulation to a brain area linked to pain can reduce chronic visceral pain in people with irritable bowel syndrome with diarrhea (IBS-D). 42 adults will receive either real or sham stimulation daily for two weeks. The goal is to see if this non-invasive treatment can safely ease symptoms.

What this could mean

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

Active substance
repetitive transcranial magnetic stimulation (rTMS)
What this could lead to
If it works, this could offer a non-drug option to reduce chronic abdominal pain in people with IBS-D.
What could go wrong
This is a small, early-stage trial with only 42 participants. The sham group mimics the experience, so the real effect may be modest or not last long.

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 42 people

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