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

Summary

This study will collect real-world data from 100 people with drug-resistant epilepsy who receive or are considered for a procedure using the OneRF Ablation System. The system uses radiofrequency energy to target and destroy small areas of brain tissue causing seizures. Researchers will track seizure control, medication changes, and device safety over time.

What this could mean

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

What this could lead to
If successful, this registry could provide real-world evidence on how well the OneRF Ablation System controls seizures in people with drug-resistant epilepsy.
What could go wrong
This is an observational registry, not a controlled trial, so results may be influenced by patient selection or other treatments. It is not designed to prove the device works better than alternatives.

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

Inclusion Criteria: 1. Patients diagnosed with drug resistant epilepsy (DRE) 2. Patients who have received or will receive EVO® sEEG-RF implants 3. Patients who have undergone or may undergo an RF ablation procedure using the OneRF Ablation System. 4. Patient, or legal guardian, understands study procedures and voluntarily signs informed consent in accordance with institutional policies. In the event that the patient is under the age of 18, the patient may also be required (per IRB) to sign an assent affirming their agreement to participate. Exclusion Criteria: 1\.
