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 Results may not be published yet.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

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 a non-invasive brain stimulation method called continuous theta burst stimulation (cTBS) can reduce anxiety in people with generalized anxiety disorder (GAD). Forty participants will be randomly assigned to receive either real or sham (placebo) stimulation over seven days, guided by their own MRI scans. Researchers will measure changes in anxiety symptoms and brain activity before and after treatment, with a follow-up two weeks later.

What this could mean

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

Active substance
Navigated continuous theta burst stimulation (cTBS) using a MagStim Rapid2 stimulator
What this could lead to
If it works, this could point toward a new, non-drug treatment option for generalized anxiety disorder that targets specific brain areas.
What could go wrong
This is a small, early-phase trial with only 40 participants, so results may not apply to everyone. The sham group helps control for placebo effects, but the treatment may still fail to show meaningful benefit.
