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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a special electrode that can record the activity of individual brain cells during epileptic seizures. Thirty adults with drug-resistant epilepsy who already need brain monitoring for surgery will have these electrodes implanted for a few weeks. The main goal is to see if the device is safe and can capture clear signals from single neurons.

What this could mean

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

Active substance
micro-macro electrode implantation
What this could lead to
If successful, this could help researchers better understand how seizures start and spread in the brain, potentially guiding future treatments.
What could go wrong
This is a small, early-stage safety study with only 30 participants. The device may cause side effects or fail to record enough neurons, and the findings may not lead to direct patient benefits.

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 30 people

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

Started

Mar 2023

Expected to finish

Sep 2027

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

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

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

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

Inclusion Criteria: * Patient 18 years old or older suffering from drug-resistant focal epilepsy. * Candidate for epilepsy surgery. * Requires evaluation with intracranial stereo-EEG electrodes. * Able and willing to provide informed consent. Exclusion Criteria: * Any acute infection (e.g. fever, throat infection). * Skin or scalp infection over the implantation site. * Thin or fragile skull bones, which would prevent stereo-EEG electrodes from being anchored safely. * Increased risk of infections, either from a medical condition or from immunosuppressant medication. * Increased risk of bleeding, either from a medical condition or from antiplatelet or anticoagulant medication. * Severe concomitant medical disease (including, but not limited to, cardiovascular, respiratory, renal or hepatic disease). * Severe concomitant psychiatric disease or major psychological distress. * Women who are pregnant or breastfeeding during the study. * Patients who have an implanted stimulation device (e.g. pacemaker, defibrillator, neurostimulator).
