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
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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.

Summary

This study tested whether a new type of brain stimulation, called controlled transcranial magnetic stimulation (cTMS), can reduce pain and improve daily function in people with painful diabetic neuropathy. Twenty adults with the condition received either real or sham cTMS over five days. The goal was to see if this non-invasive, painless procedure could offer relief where other treatments have fallen short.

What this could mean

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

Active substance
controlled transcranial magnetic stimulation (cTMS) device
What this could lead to
If it works, this could offer a new, non-drug option for managing chronic nerve pain in people with diabetes.
What could go wrong
This was a very small, early study (20 people) and previous TMS research only helped about half of patients. The results may not apply to everyone.

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.
