Evaluating fast-ripples in managing drug-refractory epilepsy

Contribution of Fast-ripples to the Improvement of the Neurosurgical Management of Drug-refractory Epilepsy

Not applicable Interventional University Hospital, Toulouse · NCT06105645

This study is testing whether using special electrodes to track fast-ripples in the brain can help doctors make better surgery decisions for people with epilepsy that doesn't respond to medication.

What this trial studies

This study aims to assess how fast-ripple information can enhance the neurosurgical management of patients with drug-refractory epilepsy using Stereo-ElectroEncephaloGraphy (SEEG). It involves two groups of patients: one receiving hybrid micro-macro electrodes that allow for fast-ripple assessment, and a control group receiving standard electrodes without this capability. The study will analyze the impact of fast-ripples on surgical decisions and patient outcomes, specifically focusing on seizure freedom one year post-surgery. A total of 440 patients will be involved across multiple centers, with data collected and analyzed by a team of experts.

Who should consider this trial

Good fit: Ideal candidates are patients suffering from drug-resistant focal epilepsy who are undergoing SEEG and have consented to participate.

Not a fit: Patients with conditions such as cardiac defibrillators or those under judicial protection may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved surgical outcomes and better seizure control for patients with drug-refractory epilepsy.

How similar studies have performed: While the use of fast-ripples in epilepsy management is a novel approach, similar studies have shown promising results in enhancing surgical decision-making.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Patient suffering from drug-resistant focal epilepsy (DRFE), as defined by the International League Against Epilepsy, undergoing SEEG, the indication of which was selected during a multidisciplinary epilepsy meeting
* Patient who has given written informed consent to allow the study data collection procedures
* Patient covered by the French healthcare system.

Exclusion Criteria:

* Patients under juridical protection (authorship, curators or safeguarding of justice).
* Patient deprived of liberty by a judicial or administrative decision
* Patient with a cardiac defibrillator
* Thermocoagulation planned on one of the potential hybrid electrodes .
* Patient in exclusion period of another study.
* No other non-inclusion criteria since the study will only be proposed to patients who already meet the criteria for a SEEG
