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 Results may not be published yet.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

Summary

This study tests whether a noninvasive device that stimulates the vagus nerve can reduce pain and other symptoms in women with fibromyalgia. Participants will receive either the nerve stimulation, standard medical treatment, or both, to see which approach works best. The goal is to find a new way to ease the widespread pain, fatigue, and emotional distress that come with fibromyalgia.

What this could mean

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

Active substance
Noninvasive vagus nerve stimulation (electrical stimulation of the vagus nerve) compared to and combined with standard medical treatment
What this could lead to
If effective, this could offer a drug-free option or add-on to help manage fibromyalgia pain and related symptoms like anxiety and depression.
What could go wrong
This is a relatively small study, and results may not apply to all fibromyalgia patients. The treatment may not prove more effective than standard care, and individual responses can vary.
