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 Results may not be published yet.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.
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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study explores whether temporarily opening the blood-brain barrier using a special electrical field during spine surgery can release brain-specific markers into the blood. Researchers will compare these blood markers to those found in spinal fluid from the same patient. If it works, it could pave the way for a simple blood test to diagnose brain and spinal cord diseases without a spinal tap.

What this could mean

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

Active substance
Barrier disrupting fields (BDF) procedure
What this could lead to
If successful, this could lead to a less invasive way to detect brain and spinal cord conditions using a simple blood test instead of a spinal tap.
What could go wrong
This is a very early feasibility study with only 20 participants. The procedure is done under anesthesia during surgery, so results may not apply to awake patients or other settings.
