Protocol Summary
Population - Target population is 10 adults (18 to 75 years of age) with a diagnosis of treatment-resistant epilepsy with at least 20 seizures per year, and whose seizure onset recorded from scalp EEG is localized to a brain region accessible by the subcutaneous EEG electrodes
Number of sites - Three sites; King's College Hospital NHS Foundation Trust, University College London Hospital NHS Foundation Trust, St George's University Hospital NHS Foundation Trust
Study design - This study is an observational, non-randomised, non-interventional study. It is not intended as a device trial. It is not intended to assess the device performance, rather the usefulness of bio-signals in seizure prediction and in detecting seizure-associated phenomena. There will be no change to usual care as a result of taking part.
A subcutaneous EEG device will be implanted under local anaesthesia to record continuous EEG and a non-invasive wrist-worn sensor will be used to acquire non-EEG bio-signals (eg. heart activity and rate, movements, muscle activity, electrodermal activity, body temperature)
Objectives - The association will be investigated between non-invasive measurable variables related to stress and sleep, semi-invasive subcutaneous EEG phenomena, and the occurrence of seizures. The predictive value of change in non-invasive variables semi-invasive subcutaneous EEG phenomena for the occurrence of seizures will be assessed.
Study Duration - Up to one year for each patient. Participants may be approached during or after this study to participate in related studies.
Funding - This study receives funding from the Epilepsy Foundation of America, Innovative Medicines Institute (IMI) and UNEEG medical A/S.

- Subjects known with or suspected abuse of alcohol (defined as consumption of > 250g alcohol per week or abuse of any other neuro-active substances
- Subjects involved in therapies with medical devices that deliver electrical energy into the area around the implant.
- Subjects at high risk of surgical complications, such as active systemic infection and hemorrhagic disease.
- Subjects who are allergic to the local anesthetics used during implantation.
- Subjects whose safety blood measurements (full blood count, U&E, clotting) are significantly out of range in the judgement of the CI.

- Subjects who have an infection at the site of device implantation.
- Subjects who operate MRI scanners or are planned to have an MRI scan within the next year.
- Subjects with profession/hobby that includes activity imposing extreme pressure variations (e.g. diving or parachute jumping). NB: diving/snorkeling is allowed to 5 meters of depth.
- Subjects with profession/hobby that includes activity imposing an unacceptable risk for trauma against the device or the site of implantation (e.g. martial art or boxing).
