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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 early study at Mayo Clinic tests a new implantable device called the Brain Interchange System in up to 8 people with drug-resistant epilepsy. The device records high-speed brain signals and can deliver targeted electrical stimulation to prevent seizures. Unlike current systems that react after a seizure starts, this one aims to detect warning signals and stop seizures before they happen. For now, the study only checks if the device works as intended, not whether it actually controls seizures.

What this could mean

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

Active substance
CorTec Brain Interchange System (implantable device for sensing and stimulation)
What this could lead to
If successful, this could pave the way for a future implant that stops seizures before they start, improving seizure control for people with drug-resistant epilepsy.
What could go wrong
This is a very early feasibility study with only 8 participants. It tests whether the device can detect and respond to brain signals, not whether it actually stops seizures. Many technical hurdles remain.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 8 people

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

Expected to start

Nov 2026

An estimate. Start dates often move.

Expected to finish

Aug 2029

An estimate. End dates often move.

Lead sponsor

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.

Ages

3 to 70 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with medically refractory epilepsy, who have been deemed appropriate candidates for intracranial EEG monitoring * Adult men and women (18≤ age \<70 years) * Children (3≤ age \<18 years) * Includes women and minorities Exclusion Criteria: • Subjects will be excluded if their condition makes them unable to continue with recordings.
