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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 pilot study tests whether a non-invasive device that gently stimulates the vagus nerve through the ear can improve letter learning in 100 adolescents with dyslexia. Participants will learn new letter-sound relationships during six 30-minute sessions while receiving either active or sham stimulation. The study also uses brain scans to see if the stimulation changes how the brain responds to letters. However, the trial is currently suspended, and the main goal is to see if the approach is feasible and tolerable.

What this could mean

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

Active substance
transcutaneous auricular vagus nerve stimulation (taVNS) device
What this could lead to
If it works, this could point toward a new way to help children with dyslexia learn letters more easily.
What could go wrong
This is a very early pilot study focused on feasibility, not proof of effectiveness. The trial is currently suspended, and results may not show clear benefits.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

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 100 people

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

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

Sep 2029

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.

Ages

10 to 12 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.
