158: Bexicaserin, the PACIFIC Trial, and Treating Developmental Epileptic Encephalopathies

Welcome to the NeurologyLive ® Mind Moments® podcast. Tune in to hear leaders in neurology sound off on topics that impact your clinical practice. In this episode, "Bexicaserin, the PACIFIC Trial, and Treating Developmental Epileptic Encephalopathies," Johannes Streffer, MD, PhD, discusses phase 1/2 findings from the PACIFIC trial evaluating bexicaserin in developmental epileptic encephalopathies, presented at the American Epilepsy Society 2025 Annual Meeting. Streffer, senior vice president of clinical development at Lundbeck, outlines the scientific and clinical rationale for studying DEEs as a unified population, emphasizing the unmet need and complexity of trial design in this highly vulnerable group. He reviews key efficacy outcomes, including sustained reductions in countable motor seizures and strong patient retention through long-term open-label extension and expanded access follow-up. The discussion also explores safety and tolerability considerations in patients receiving multiple concomitant antiseizure medications, the highly selective mechanism of action of bexicaserin, and how Lundbeck’s broader strategy in rare neurological disorders aims to de-risk development early while addressing populations with limited therapeutic options.
