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 Results may not be published yet.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.
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

Summary

This pilot study tests a procedure called TEMMA, where doctors insert small coils into an artery in the lining of the brain to treat migraine. The study will enroll 25 adults aged 18-60 who have migraine at least 8 days per month and have not gotten relief from at least two preventive medications. Researchers will track changes in headache days, pain intensity, and medication use over 12 months to see if the procedure is safe and provides lasting benefit.

What this could mean

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

Active substance
middle meningeal artery coil embolization (TEMMA procedure using FDA-cleared coils)
What this could lead to
If it works, this could offer a new, lasting treatment option for people with hard-to-treat migraine who haven't responded to medications.
What could go wrong
This is a very early, small pilot study with only 25 people and no control group. The procedure involves risks from angiography and embolization, and it may not reduce migraines for everyone.

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Mar 2026

An estimate. Start dates often move.

Expected to finish

Mar 2028

An estimate. End dates often move.

Lead sponsor

A company

The lead sponsor is a pharmaceutical, biotech, or medical-device company.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
