Longboard Pharmaceuticals’ Presence at American Epilepsy Society (AES) Annual Meeting Reinforces Ongoing Commitment to the Rare Epilepsy Community

Longboard Pharmaceuticals, Inc. (Nasdaq: LBPH), a clinical-stage biopharmaceutical company focused on developing novel, transformative medicines for neurological diseases, today announced that it will present data for LP352, a novel, highly selective investigational treatment in development for seizures associated with a range of Developmental and Epileptic Encephalopathies (DEEs), in poster sessions at the 2023 AES Annual Meeting. Longboard will also host a scientific exhibit with members of its leadership team to highlight details of the ongoing PACIFIC study, and to discuss LP352 as a potential best-in-class therapy for people living with rare seizure disorders.

“We believe that LP352 has the promise to be a best-in-class therapy for a broad range of DEEs, and we remain committed to moving the space forward. The AES annual meeting gives us the opportunity to collaborate live with the top thought leaders, as we approach PACIFIC topline data in January 2024 and plan for our Phase 3 program for LP352. We look forward to presenting new posters and hosting a scientific exhibit to highlight the differentiating qualities of LP352 and our unique development plan. I am also pleased to continue our work with key advocacy organizations, including participation in the Rare Epilepsy Network’s panel: Clustering Rare Epilepsies for Research, Trials & Care,” stated Dr. Randall Kaye, Longboard’s Chief Medical Officer.
