AI Summary
Jazz Pharmaceuticals plc announced that nine company-sponsored Epidiolex® (cannabidiol) posters will be presented at the American Epilepsy Society (AES) 2024 Annual Meeting in Los Angeles from December 6-10, 2024. These presentations include new insights into Epidiolex’s benefits for patients with rare epilepsies, with a special focus on data from the EpiCom trial—the first prospective study evaluating the impact of adjunctive Epidiolex on tuberous sclerosis complex (TSC)-associated neuropsychiatric disorders. The EpiCom data revealed improvements in the severity of behavioral symptoms following treatment initiation. Additionally, real-world outcomes from the BECOME surveys (BECOME-TSC and BECOME-LTC) highlight both seizure and non-seizure improvements, as reported by caregivers and nurses, affirming the broad benefits of Epidiolex. These findings are anticipated to enhance the understanding of Epidiolex’s impact beyond seizure control, addressing significant unmet needs in epilepsy treatment.

Announcement
Jazz Pharmaceuticals plc announced that the Company will present eight abstracts at the 15th European Epilepsy Congress (EEC), including a subgroup analysis of the BECOME (BEhavior, COgnition and More with Epidyolex®) Caregiver Survey, a survey of caregivers of patients with Lennox-Gastaut syndrome (LGS) or Dravet syndrome (DS) reporting outcomes in patients receiving Epidiolex/Epidyolex (cannabidiol, 100mg/mL oral solution) and concomitant clobazam.
AI Summary
Jazz Pharmaceuticals plc announced it will present eight abstracts at the 15th European Epilepsy Congress (EEC). One key presentation is a subgroup analysis of the BECOME Caregiver Survey. This survey gathered real-world insights from caregivers of patients with Lennox-Gastaut syndrome (LGS) or Dravet syndrome (DS) who were treated with Epidiolex/Epidyolex (a 100mg/mL cannabidiol oral solution) combined with clobazam. The findings demonstrate that most caregivers reported improvements in both seizure-related outcomes and non-seizure measures such as alertness, cognition, and language. These results underline Epidyolex’s potential for enhancing the overall well-being of patients beyond just seizure control. Additional analyses from pivotal trials further support the clinical benefits associated with reduced drop seizures, reinforcing the holistic impact of Epidyolex for patients and their families.

Announcement
Jazz Pharmaceuticals plc announced top-line results from the Phase 3 open-label, single-arm trial in Japan evaluating the safety and efficacy of cannabidiol oral solution (marketed as Epidiolex®/Epidyolex® globally) as an adjunctive treatment for seizures associated with Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS) or tuberous sclerosis complex (TSC).
AI Summary
Jazz Pharmaceuticals announced top-line results from its Phase 3, open-label, single-arm trial in Japan, which evaluated the safety and efficacy of its cannabidiol oral solution (marketed as Epidiolex®/Epidyolex®) as an add-on treatment for seizures linked to Lennox-Gastaut syndrome, Dravet syndrome, and tuberous sclerosis complex in pediatric patients. Although the trial did not meet its primary efficacy endpoint of a pre-specified change in seizure frequency over a 16-week period compared to baseline, the study did observe numeric improvements in both the primary and several secondary endpoints.
No new safety issues were identified during the trial. Building on Epidyolex’s established clinical profile from five global Phase 3 studies involving over 900 patients, Jazz Pharmaceuticals plans to continue collecting data in Japan and to consult with regulatory authorities about a potential new drug application, addressing the significant unmet needs in pediatric rare epilepsies.
