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 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 Results may not be published yet.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

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.

Summary

This study tests whether combining two types of stimulation—one that targets a nerve in the ear (or a surgically implanted neck device) and another that uses magnetic pulses on the scalp—can better relieve symptoms of treatment-resistant depression. Participants attend six treatment sessions, receiving each type alone or both together, to see which combination works best. The goal is to find a more effective option for people whose depression hasn't improved with standard treatments.

What this could mean

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

Active substance
Vagus nerve stimulation (VNS) and transcranial magnetic stimulation (TMS)
What this could lead to
If it works, this combined approach could offer a new treatment option for people with depression that hasn't responded to standard therapies.
What could go wrong
This is a small, early-phase study with only 24 participants, so results may not apply broadly. The treatment may cause side effects or not improve symptoms significantly.
