Longboard Pharmaceuticals to Host Investor & Analyst Event in New York on October 11, 2023

LA JOLLA, Calif.--(BUSINESS WIRE)-- Longboard Pharmaceuticals, Inc. (Nasdaq: LBPH), a clinical-stage biopharmaceutical company focused on developing novel, transformative medicines for neurological diseases, today announced that it will host an Investor & Analyst Event focused on the Developmental and Epileptic Encephalopathy (DEE) landscape and LP352, a first-in-class 5-HT2C receptor superagonist in development for the potential treatment of seizures associated with DEEs.

The event will feature DEE thought leaders who will discuss the unmet medical need and current and emerging treatment landscape for people living with refractory epilepsies.

The Longboard Pharmaceuticals team will discuss the opportunity within the DEE landscape and the ongoing Phase 1b/2a PACIFIC Study evaluating LP352 as a potential treatment of seizures associated with a broad range of DEEs. The PACIFIC Study is fully enrolled, and topline data are expected around year-end 2023.

A live question and answer session will follow the formal presentations.

ABOUT LP352

LP352 is an oral, centrally acting, 5-HT2C superagonist in development for the potential treatment of seizures associated with DEEs such as Lennox-Gastaut syndrome, Dravet syndrome, SCN2A-related epilepsies, CDKL5 deficiency disorder, and other epileptic disorders. LP352 is designed to modulate GABA and, as a result, suppress the central hyperexcitability that is characteristic of seizures. LP352 has novel chemistry and attributes, and was designed to be highly specific and selective for the 5-HT2C receptor subtype, giving it the potential to reduce seizures in patients with DEEs while overcoming the known or perceived safety limitations of available drugs in the 5-HT2 class. LP352 is currently being evaluated in a Phase 1b/2a clinical trial (the PACIFIC Study) in participants with DEEs, with topline data expected around year-end 2023, as well as in additional supportive studies.

ABOUT THE PACIFIC STUDY

The PACIFIC Study is a Phase 1b/2a clinical trial evaluating participants with DEEs. The primary objectives of the study are to assess the safety and tolerability of LP352. The PACIFIC Study will also evaluate change in seizure frequency over the treatment period. The study enrolled 52 participants with a variety of treatment resistant seizures that fall into the category of DEE across approximately 30 study sites in the United States and Australia. The PACIFIC Study data are expected to inform the design and characteristics of the planned Phase 3 program for LP352. Participants who complete the PACIFIC Study are eligible to roll over into the ongoing open-label extension (OLE) trial should they choose to do so. The OLE is a Phase 2 multicenter, open-label, multiple-dose, long-term extension clinical trial designed to evaluate long-term safety of LP352 in participants with DEEs who have completed the PACIFIC Study.
