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 This study
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 Results may not be published yet.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 tests two types of theta burst stimulation, a non-invasive brain stimulation technique, to relieve chronic nerve pain caused by chemotherapy in breast cancer survivors. Forty participants will receive both types of stimulation at different times, with brain scans used to guide treatment. The goal is to find which method works best and understand how it changes pain-related brain networks.

What this could mean

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

Active substance
theta burst stimulation (TBS)
What this could lead to
If successful, this could offer a non-drug, brain-based treatment option for chronic nerve pain caused by chemotherapy in breast cancer survivors.
What could go wrong
This is a small, early-stage trial with only 40 participants, so results may not apply to everyone. The effects may be temporary or not work for all patients.
