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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is testing whether a high-resolution EEG (HR-EEG) can better predict which children with drug-resistant focal epilepsy will have successful surgery. About 120 children will have a painless HR-EEG recording before surgery. Researchers will compare the pattern of brain signals to see if a tight cluster of signals predicts better outcomes. The goal is to help more children get this underused treatment.

What this could mean

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

Active substance
High-resolution EEG (HR-EEG) recording
What this could lead to
If successful, this could help doctors better identify children who will benefit from epilepsy surgery, leading to more successful surgeries and fewer seizures.
What could go wrong
This is an observational study, not a treatment trial. The test may not improve prediction accuracy as hoped, and results may not apply to all children with epilepsy.

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 120 people

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

Started

May 2024

Expected to finish

Nov 2026

An estimate. End dates often move.

Lead sponsor

A government agency

The lead sponsor is a government body.

Who can take part

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

Ages

2 to 17 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: 1. Age≥2 and \<17 years; 2. Drug-resistant focal epilepsy (failure of at least 2 well-conducted drug trials); 3. Phase 1 pre-op evaluation with scalp video-EEG recording, MRI and PET-FDG suggesting that the patient could be a good candidate for epilepsy surgery; 4. Recent scalp EEG record (within 12 months) showing the presence of interictal spikes; 5. High-quality and recent (within 6 months) structural MRI with 3D-T1 sequences covering the whole brain and the scalp available. Exclusion Criteria: 1. Behavioral deficits making recording of scalp EEG impossible without sedation; 2. Informed consent form not signed by the parents; 3. Patient not affiliated to a social security system
