SAN DIEGO–(BUSINESS WIRE)–$LBPH #Epilepsy—Longboard Pharmaceuticals, Inc. (Nasdaq: LBPH), a clinical-stage biopharmaceutical company focused on developing novel, transformative medicines for neurological diseases, today provided a corporate update and reported financial results for the full year 2022.

“I am very proud of the team for the progress that we made in 2022, including the strong engagement and excitement we have generated around the PACIFIC Study, which remains on track to deliver topline data in the second half of this year. We continue to think strategically on ways to truly differentiate LP352 in the clinic as a potential best-in-class treatment option for individuals living with DEEs. For LP659, we plan to initiate our first in-human study in the coming months, and anticipate topline SAD data in the second half of the year,” stated Kevin R. Lind, Longboard’s President and Chief Executive Officer.

2022 PROGRAM HIGHLIGHTS AND ANTICIPATED 2023 MILESTONES

LP352 Highlights:

LP352 is an oral, highly selective, centrally acting 5-hydroxytryptamine 2C receptor subtype (5-HT2C) superagonist. LP352 is the only 5-HT2C receptor agonist being dose optimized for developmental and epileptic encephalopathies (DEEs). We believe LP352 could be a treatment for individuals with DEEs where no options are available and a potentially safer, more efficacious, easy to add-on treatment option for individuals with syndromes where current therapies are inadequate.

The PACIFIC Study

The PACIFIC Study is an ongoing Phase 1b/2a basket clinical trial of LP352. We plan to evaluate 50 participants ages 12 to 65 years old with DEEs. We are utilizing approximately 30 study sites across the United States and Australia in the trial.

• Full enrollment expected in the first half of 2023
• Topline data expected in the second half of 2023
• PACIFIC Study data is expected to inform the design and characteristics of our Phase 3 program

The 102 Phase 1 Central Nervous System (CNS) Pharmacokinetics (PK) and Pharmacodynamics (PD) Study

In December 2022, we reported positive topline data from cohorts 1 and 2 of an ongoing Phase 1 clinical study evaluating the CNS PK and PD of LP352 in healthy volunteers.

• LP352 exhibited a strong correlation between plasma and cerebrospinal fluid PK concentration, which increased in a dose-dependent and consistent manner
• LP352 demonstrated early quantitative electroencephalogram (qEEG) changes, and sustained effects on qEEG activity after continuous dosing in a dose-dependent manner indicating receptor engagement
• Favorable safety and tolerability results were observed, with adverse events generally consistent with previous clinical studies

Presented and hosted a Scientific Exhibit at the American Epilepsy Society (AES) Annual Meeting

• New posters included the following:
  • Searching for Safer and More Effective Medications in the Management of Seizure Disorders: A 5-HT2C Superagonist
  • Evaluation of Prolactin as a Useful Pharmacodynamic Tool to Assess Engagement of Central 5-HT2C Receptors by LP352, a Potent and Selective 5-HT2C Agonist

• Presentation materials from AES and other medical meetings can be found on the “Our Approach” section of our website here

LP659 Highlights:

LP659 is a centrally acting, S1P1,5 receptor modulator. LP659 was designed for optimized pharmacology, PK and engagement of S1P1,5, which may lead to improved efficacy and safety. We believe LP659 could have potential in a number of inflammatory neurological conditions.

Initiating First In-Human (FIH) Clinical Trial of LP659 in Healthy Volunteers

• Expect to initiate clinical trial in the first half of 2023
• Phase 1 topline SAD data expected in the second half of 2023

CORPORATE AND FINANCIAL UPDATES

Continued to add key expertise across the company with the goal of cultivating a world-class neuroscience team to advance our programs in a strategic manner

• Expanded our team from 22 to 33 employees during 2022
• Added key leaders to our team with extensive experience in the epilepsy space, including commercial strategy, clinical development and medical affairs

Completed a $23.0 million public offering of common shares

• We further strengthened our institutional shareholder base by completing a follow-on public offering of 5,750,000 shares of our voting common stock in February 2023. Gross proceeds were $23.0 million.
