Brief Summary:
The RNS System Pivotal study is designed to assess safety and demonstrate that the RNS System is effective as an adjunctive add-on therapy in reducing the frequency of seizures in individuals 18 years of age or older with partial onset seizures from no more than two foci two areas of the brain that are refractory drug-resistant or hard-to-treat to two or more antiepileptic medications Patients continue to receive their epilepsy medications while participating in the study
Detailed Description:
NeuroPace Inc is sponsoring an investigational device study of the RNS System the first closed loop responsive brain stimulator designed to treat refractory epilepsy The RNS System Pivotal study is a multi-center randomized double-blinded sham-stimulation controlled investigation being conducted at 32 epilepsy centers throughout the United States The study is designed to assess safety and demonstrate that the RNS System is effective in reducing the frequency of medically uncontrolled and disabling partial onset seizures that start from one or two areas of the brain
The RNS Neurostimulator a pacemaker-like device and NeuroPace Leads tiny wires with electrodes are implanted in the head The Neurostimulator is a battery powered microprocessor controlled device that detects and stores records of electrographic patterns such as epileptiform or seizure-like activity from the Leads within the brain When the device detects an electrographic pattern it responds by sending electrical stimulation through the Leads to a small part of the patients brain to interrupt the electrographic pattern This type of treatment is called responsive stimulation but it is not yet known if it will work for the treatment of epilepsy Direct brain stimulation therapy has already received approval in the United States Europe Canada and Australia for the treatment of Essential Tremor and Parkinsons disease Direct brain stimulation is not approved for the treatment of epilepsy
Subjects participating in the RNS System Pivotal study must met inclusion criteria including localization of epileptogenic regions prior to enrolling in the study Throughout the entire study subjects or their caregivers must keep a seizure diary Seizure frequency seizure severity and antiepileptic medications as well as physical and emotional health will be monitored and recorded throughout the study
Upon demonstrating the required seizure frequency and stable antiepileptic medications over 3 consecutive months of the Baseline pre-implant Period subjects will qualify for RNS System implantation Antiepileptic medications should continue to remain stable until 6 months post-implant The surgical procedure will be performed within one month of qualification
The RNS Neurostimulator is cranially implanted and connected to one or two NeuroPace Leads implanted in the brain The investigational team will determine the placement of the Leads based on prior localization of the epileptogenic region according to standard localization procedures Detection of epileptiform activity will be enabled for all subjects during the 1 month Post-Operative Stabilization Period Subjects will be randomized 11 to either the Treatment or Sham group prior to starting the 1 month Stimulation Optimization Period During this period subjects are seen on a weekly basis by the Treatment Protocol investigator Responsive stimulation will be enabled and optimized for subjects randomized to the Treatment group Subjects randomized to the Sham group will be seen for simulated stimulation programming in order to maintain the treatment blind
The Blinded Evaluation Period is comprised of months 3 4 and 5 post-implant Subjects in the Treatment group will receive responsive stimulation and subjects in the Sham group will not Subjects will not know whether responsive stimulation is being delivered or not At the end of the 5th month all subjects transition into the Open Label Evaluation Period during which all subjects may receive responsive stimulation and antiepileptic medications may be adjusted as medically required
Subjects will be followed for 2 years post-implant Throughout study participation both effectiveness and safety data will be monitored continuously and reviewed and documented by the study investigator at study appointments scheduled every month for the first year post-implant then every 3 months
