NeuroPace Announces Data From a Long-Term Post-Approval Study of the RNS System in Focal Epilepsy at the 2025 AAN Annual Meeting

Three-year data from the largest FDA-reviewed prospective neuromodulation study of safety and effectiveness in drug-resistant focal epilepsy1Long-term seizure reduction with a median reduction of 82% at 3 years.Seizure freedom with 42% of patients remaining seizure free for 6+ months.i MOUNTAIN VIEW, Calif., April 08, 2025 (GLOBE NEWSWIRE) -- NeuroPace, Inc. (Nasdaq: NPCE), a medical device company focused on transforming the lives of people living with epilepsy, today announced three-year effectiveness data from the Post-Approval Study (PAS) of the RNS® System, which showed an 82% median reduction in seizures in adults treated with brain-responsive stimulation for drug-resistant focal epilepsy (DRE).1 The data were presented in an oral presentation at the American Academy of Neurology (AAN) Annual Meeting, taking place in San Diego from April 5-9, 2025. “Drug-resistant epilepsy is a significant unmet medical need, accounting for up to 30-40% of all epilepsy diagnoses and affecting approximately 1.2 million people in the U.S.,” said Martha Morrell, M.D., NeuroPace’s Chief Medical Officer. “Our ongoing clinical programs aim to expand on the long-term clinical evidence of the safety and effectiveness of the RNS System, which is the only FDA-approved epilepsy device that provides brain-responsive neurostimulation. These results presented at AAN add to the growing body of evidence that demonstrates consistency in the power of combining neurostimulation with long-term direct brain data to provide seizure control for people who live with DRE.” The PAS enrolled 324 patients from 32 centers making it the largest-ever, FDA-reviewed, prospectively enrolled trial in the field of neuromodulation for drug-resistant focal epilepsy.1,2,3 ii Data from the prespecified three-year effectiveness analysis presented at the AAN Annual Meeting showed continued evidence of substantial seizure reductions with the RNS System for all types of DRE focal epilepsy. Most notably, the data showed1: Long-term seizure reduction with a median reduction of 82% at 3 years.Rapid seizure reduction with a median reduction of 62% at 6 months.Seizure freedom with 42% of patients remaining seizure free for 6+ months.1 in 3 patients did not require intracranial EEG monitoring. Focal epilepsy is the most common form of DRE and often results in a lifetime of debilitating seizures from the time of childhood or adolescence and, if uncontrolled, can result in poor cognitive outcomes, depression, decreased social interaction, increased seizure frequency, and sudden unexplained death in epilepsy (SUDEP). The RNS System delivers greater seizure reduction than other neuromodulation therapies1,4 ,5 ,ii and is the first and only neuromodulation platform that delivers personalized, real-time seizure treatment. “We are committed to helping people with drug-resistant epilepsy attain seizure freedom and a better standard of care,” said Joel Becker, NeuroPace’s Chief Executive Officer. “The substantial seizure reduction data reported in this study thus far – the largest FDA-reviewed prospective study in neuromodulation history for focal DRE – furthers our goal of getting physicians the data they need to confidently select and provide ongoing treatment for their patients.”The three-year safety and effectiveness data of the RNS System in adults with drug-resistant focal epilepsy from the PAS were submitted to the FDA in November 2024, and the study will continue to five years as part of its initial FDA approval. Abstract program number S20.009 was presented at the AAN 2025 Annual Meeting on Monday, April 7, 2025.
