About

The primary objective of this research is to study the efficacy and safety of Stereotactic EEG (SEEG) guided radio-frequency thermocoagulation (RF-TC) of Subiculum as adjunctive therapy for reducing the frequency of seizures in drug-resistant temporal lobe epilepsy with Mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS).

Full description

Mesial temporal lobe epilepsy (mTLE) is the most classical subtype of temporal lobe epilepsy, which is the indication of surgical intervention after evaluation. This project aims to include 20 participants, and evaluate the effectiveness and safety of Stereotactic EEG (SEEG) guided radio-frequency thermocoagulation (RF-TC) of Subiculum in patients with mesial temporal lobe epilepsy with hippocampal sclerosis through A prospective, interventional, unblinded, single-arm clinical trial. It is expected to provide new therapeutic options for patients with mTLE-HS with alternative treatment options.

Inclusion criteria

Participants are between the ages of 14 -65 years of age
Refractory to anti-seizure medications (ASMs).
Persistence of disabling seizures at least 2 times per month during the Baseline Phase，with no more than 30 days between seizures during the Baseline Phase.
Hippocampal atrophy on MRI T1 imaging with increased ipsilateral mesial signal on T2 imaging
Interictal EEG shows focal or lateralized spikes on temporal, frontal zone, or sphenoid electrode
Ictal EEG onset is focal or lateralized on the ipsilateral side
Ipsilateral temporal focal hypometabolism on PET
Must be agreed by a consensus of ipsilateral mesial temporal origin by a multidisciplinary discussion

Exclusion criteria

Diagnosed with generalized or hereditary epilepsy with ion channel gene mutations;
Psychogenic non-epileptic seizures within 12 months;
Presence of implanted electrical stimulation medical device anywhere in the body (e.g., pacemaker, spinal cord stimulator, responsive neurostimulation) or any metallic implants in the head (e.g., aneurysm clips, cochlear implants). Note: Vagal nerve stimulators are allowed if the parameter remains stable for at least 3 months prior to the screening visit;
Risk factors that would put the participant at risk for intraoperative or postoperative bleeding. (e.g., coagulation abnormalities, etc.) or the need for chronic anticoagulation or antiplatelet aggregation medications;
IQ < 55 or severe cognitive dysfunction, unable to complete the study;
Diagnosed with a progressive neurological disorder (including progressive Rasmussen's encephalitis, etc.);
Diagnosed with a severe neuropsychiatric disorder such as dementia, major depression (admission to a psychiatric specialty/hospital within 5 years or any suicidal or self-injurious tendencies), schizophrenia, or neurodegenerative disorders;
Diagnosed with other serious physical disorders, internal diseases or severe abnormalities in liver or kidney function;
Pregnant, or planning to pregnant within 2 years;
Participation in another clinical study within 3 months;
Not suitable for enrollment as assessed by the multidisciplinary team of the center.
