SAN DIEGO, Aug. 04, 2022 (GLOBE NEWSWIRE) -- 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 second quarter ended June 30, 2022.

“I am pleased with the progress our team has made this quarter. We remain on track to complete the PACIFIC Study in the second half of 2023 by focusing our efforts on site activation and recruitment, including the planned expansion into Australia and the Australian Epilepsy Clinical Trial Network. We have also aligned with regulators to expand the age range of patients to include adolescents, and we have added an open-label extension study which will allow us to offer long-term access of LP352 to eligible study participants. Importantly, the addition of younger patients in the PACIFIC Study will provide the opportunity to evaluate the potential impact of LP352 earlier in the treatment journey. We are encouraged by our interactions with the highly engaged and enthusiastic refractory epilepsy community," stated Kevin R. Lind, Longboard’s President and Chief Executive Officer. "We also continue to make progress on IND-enabling activities for LP659 and we look forward to updating our stakeholders as we advance our promising pipeline.”

Program Overview:

• LP352, an oral, highly selective, centrally acting 5-hydroxytryptamine 2C receptor subtype (5-HT2C) superagonist:
  • The PACIFIC Study, a Phase 1b/2a basket trial, evaluating approximately 50 participants ages 12 to 65 years old with developmental and epileptic encephalopathies or DEEs, such as Dravet syndrome, Lennox-Gastaut syndrome, tuberous sclerosis complex, CDKL5 deficiency disorder, SCN2A-related disorders, among others, is ongoing with expected completion in the second half of 2023.
  • Multiple clinical and preclinical studies are in process to further elucidate the intrinsic PD/PK properties and support clinical development in a broad range of refractory epilepsies.
    

• LP659, an oral, selective, centrally acting S1P receptor modulator targeting multiple neurological diseases, is currently in IND-enabling studies with IND application submission to the FDA expected in the fourth quarter of 2022.

Balance Sheet Highlights

At June 30, 2022, Longboard’s cash, cash equivalents and short-term investments were approximately $87.4 million. Our cash position is expected to support operations into 2024 based on our current business plan.  

Operating Results

Research and development (R&D) expenses were $8.9 million for the three months ended June 30, 2022, an increase of $4.0 million, or 82%, compared to $4.9 million for the three months ended June 30, 2021. The net increase of $4.0 million is primarily related to increases of $1.7 million in clinical and preclinical trial expenses related to LP352, $1.1 million in personnel-related expenses, and $0.9 million in preclinical expenses related to LP659 and LP143.

General and administrative (G&A) expenses were $2.6 million for the three months ended June 30, 2022, an increase of $0.5 million, or 28%, compared to $2.1 million for the three months ended June 30, 2021. The net increase of $0.5 million is primarily related to an increase in personnel-related costs.

Net loss was $11.4 million, or $0.67 per share, for the three months ended June 30, 2022 compared to $7.0 million, or $0.41 per share, for the three months ended June 30, 2021.
