RNS® System Epilepsy Post-Approval Study

NeuroPace, Inc. is sponsoring a post-approval study (PAS) of the RNS System device. The RNS System is the first FDA-approved closed loop responsive neurostimulator designed to reduce the frequency of seizures in individuals with partial onset seizures. The RNS System Epilepsy PAS is a 5 year, non-randomized, open-label, multi-center prospective observational study. Data regarding safety and efficacy are collected at enrollment and periodically throughout the 5-year study. The study is designed to assess the long-term safety and effectiveness of the RNS System as an adjunctive therapy in reducing the frequency of seizures in individuals 18 years of age or older with partial onset seizures who have undergone diagnostic testing that localized no more than 2 epileptogenic foci, are refractory to two or more antiepileptic medications, and currently have frequent and disabling seizures (motor partial seizures, complex partial seizures and/or secondarily generalized seizures). Data from the RNS System Epilepsy PAS will be used to calculate long-term SAE rates, median percent change in seizure frequency (from pre-implant retrospective data), as well as other safety and effectiveness endpoints.
