Eligibility
Key inclusion criteria
1. Subject has disabling partial seizures and/or secondarily generalized partial seizures. Disabling refers to seizures that are severe enough to cause injuries or to significantly impair areas of function such as employment, psychological or social wellbeing, or mobility.
2. Subject has failed treatment with a minimum of two AED's used in typical therapeutic dosages.
3. For three months prior to enrollment, subject's anti-epileptic medication dosages have been stable and subject has had at least two disabling seizures per month, on average, with a seizure-free interval not to exceed 45 days. Seizures must be separated by a minimum of eight hours not to be considered part of a cluster. A cluster, for the purpose of this criterion, shall be considered a single seizure.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. For three months prior to enrollment, subject's anti-epileptic medication dosages have not been stable, or subject has had more than 12 disabling seizures per month, on average, or there was a seizure-free interval longer than 45 days. Clinical seizures must be separated by a minimum of eight hours to not be considered part of a cluster. A cluster, for the purpose of this criterion, shall be considered a single seizure.
2. Subject is implanted with pacemaker, implantable cardiac defibrillator, cardiac management product, or a medical device that interferes with the SAS or with which the SAS interferes. This includes, but is not limited to, direct brain neurostimulators, spinal cord stimulators, vagus nerve stimulators (VNS), and cochlear implants. Patients with a vagus nerve stimulator implanted but turned off through the duration of the study may be enrolled, provided their clinical status has been stable for at least one month with VNS turned off.
3. Subject has been diagnosed with primary generalized seizures.
