Children's Adaptive Deep Brain Stimulation for Epilepsy Trial (CADET): Pilot

Not Applicable
Recruiting
Conditions
Epilepsy
Lennox-Gastaut Syndrome, Intractable
Interventions
Device: Deep brain stimulation
Registration Number
NCT05437393
Lead Sponsor
University College, London
Brief Summary

The CADET Pilot will investigate the safety and feasibility of deep brain stimulation (DBS) to treat children with Lennox-Gastaut syndrome using a novel DBS device (Picostim DyNeuMo-1).

Following a 30-day preoperative/baseline assessment phase, all children will have a neurosurgical procedure to implant the device. Implantation will be followed by a 30-day phase of no stimulation (the device is off / inactive) and then a six-month phase of active stimulation (the device is on / active).

Detailed Description

The CADET pilot will be a single-arm, multi-site, interventional clinical trial. This design has been chosen since this is a feasibility and safety trial in a small number of patients and thus does not primarily aim to determine efficacy.

In this pilot clinical trial, four children with drug-resistant LGS will undergo bilateral CMN DBS.

Following the DBS insertion, all children will undergo one month of inactive ('off') DBS in order to allow the lesioning effect of electrode implantation to dissipate. Thereafter, children will receive active ('on') DBS therapy with standard stimulation parameters for six-months. Following the 'on' phase of the trial, the child will then transition into continuing clinical care and will have their stimulation parameters altered according to clinical evaluation.

Primary Outcome Measures
NameTimeMethod
Ability of the participant/parent(s)/guardian(s) to re-charge and maintain the deviceFollowing 6-months of active stimulation

Device recharging is measured using the Picostim event logs

Adverse evensFollowing 6-months of active stimulation

Measured according to pre-determined device-related AEs and SAEs, as well as generic AEs and SAEs.

Willingness of the participants/parents/guardians for the participant to be recruited into the study and to undergo the interventionFollowing 6-months of active stimulation

Consent at baseline

Participant completion of the studyFollowing 6-months of active stimulation

Completion of all study activities at study exit

Secondary Outcome Measures
NameTimeMethod
Relative change in electrographic-recorded seizure frequencyFollowing 6-months of active stimulation (compared to baseline)

Measured using serial electroencephalography (EEG)

Relative change in quality of lifeFollowing 6-months of active stimulation (compared to baseline)

Measured on the Impact of Pediatric Epilepsy Scale (IPES) questionnaires. The minimum score is 0 and the maximum score is 100, with improving quality of life with ascending values.

Relative change in parent-reported seizure frequencyFollowing 6-months of active stimulation (compared to baseline)

Measured using parent-reported diaries

Relative change in seizure severityFollowing 6-months of active stimulation (compared to baseline)

Measured using the Hague Seizure Severity Scoring questionnaire. Minimum score = 13; maximum score = 52; with higher seizure severity with ascending values.
