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 Results may not be published yet.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 at the University of Pennsylvania is testing whether personalized brain stimulation can reduce negative emotions in people with depression and anxiety. Researchers will use brain scans to map each participant's negative emotion patterns, then apply different types of transcranial magnetic stimulation (TMS) to find the best frequency for disrupting those patterns. The goal is to see if the optimal stimulation can improve symptoms like rumination over two 3-day sessions.

What this could mean

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

Active substance
Transcranial Magnetic Stimulation (TMS)
What this could lead to
If successful, this could lead to a personalized brain stimulation treatment that reduces rumination and negative emotions in people with depression or anxiety.
What could go wrong
This is an early-stage study with only 40 participants, so results may not apply to everyone. The optimal stimulation frequency may not work better than the least optimal one.

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.
