Lundbeck's Promising Results for Bexicaserin in Patients with Severe Epileptic Disorders

Lundbeck Reports Positive Results from PACIFIC Trial Extension

H. Lundbeck A/S, the renowned biopharmaceutical company committed to brain health, has announced promising results from the 12-month open-label extension of the Phase 1b/2a PACIFIC trial. Bexicaserin, a novel treatment for individuals aged 12 to 65 with Developmental and Epileptic Encephalopathies (DEEs), demonstrated a notable median seizure reduction of 59.3% for countable motor seizures during the trial.

Overview of the PACIFIC Trial

The PACIFIC trial, which initially assessed the efficacy and safety of bexicaserin, included participants diagnosed with varied forms of DEEs such as Dravet syndrome and Lennox-Gastaut syndrome. Patients underwent a rigorous screening followed by a dose titration period to determine the highest tolerated dose. This was followed by a maintenance phase, after which participants had the opportunity to enroll in the ongoing open-label extension (OLE) study.

With 100% of PACIFIC trial completers opting to continue into the OLE, the results indicate a strong interest and trust in bexicaserin. During the 12 months of treatment, a vast majority of participants—approximately 92.7%—successfully maintained their treatment regimen. This achievement underscores the medication's promising safety and tolerability profile.

Efficacy and Safety Results

In terms of lifelong implications, the PACIFIC OLE study appears monumental, with investigators noting that the median change in seizure frequency reflected a substantial decline when comparing initial seizure counts to those observed after one year of treatment. Specifically, participants who were previously on placebo saw a decrease of 58.2%, while those originally on bexicaserin experienced a 60.4% reduction.

Though some participants reported treatment emergent adverse events, including upper respiratory tract infections and mild gastrointestinal issues, these incidents were consistent with prior findings and manageable overall, demonstrating that the benefits of long-term treatment outweigh the risks.

Lundbeck's Vision for Bexicaserin

Lundbeck's acquisition of Longboard Pharmaceuticals, which initially developed bexicaserin, signifies a bold venture into tackling complex neurological disorders with innovatively targeted therapies. Johan Luthman, Lundbeck's EVP, noted that these encouraging results solidify their commitment to long-term brain health solutions for patients battling DEEs. The favorable safety data observed in these trials bolsters confidence in bexicaserin as a potential best-in-class medication, addressing a critical need for effective treatment options in this underserved demographic.

As research and development in the realm of neuroscience continues to evolve, Lundbeck’s steadfast dedication to enhancing brain health shows promise not only for patients but also for the field of neuropharmaceuticals overall. The expectation is that full study results will be shared at an upcoming medical conference in 2025, where more detailed analyses will provide insights into bexicaserin's potential for widespread clinical use.

Conclusion

In conclusion, Lundbeck's advancements through the PACIFIC trial indicate a significant stride towards developing effective treatments for those suffering from high-impact neurological disorders. Bexicaserin stands out not just for its efficacy but as a hopeful avenue for patients seeking relief from debilitating conditions. As we head towards a future filled with possibilities in neurological therapies, Lundbeck's innovative work remains a beacon of hope for thousands affected by DEEs worldwide.
