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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers at Mayo Clinic are testing whether a device called MAVEN can record brain signals as well as the standard Alpha Omega system during deep brain stimulation surgery. The trial enrolls 30 patients with essential tremor, Parkinson's disease, or dystonia who are already scheduled for DBS. During surgery, surgeons use both devices at the same time and compare the recordings. The goal is to see how often the two devices agree.

What this could mean

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

Active substance
MAVEN, a device that records brain electrical activity and neurotransmitter signals during deep brain stimulation surgery
What this could lead to
If MAVEN records the same brain signals as the standard device, it could offer surgeons another tool for guiding deep brain stimulation electrode placement.
What could go wrong
The trial is small and only compares recordings during surgery, so it cannot show whether MAVEN improves patient outcomes. The device may not match the standard recordings well enough to be useful.
