Jazz Pharmaceuticals to present latest findings on sleep disorders and epilepsy at AAN 2025
Jazz Pharmaceuticals plc announced that seven abstracts from across its neuroscience portfolio will be featured at the 77th Annual American Academy of Neurology Meeting (AAN) being held April 5-9, 2025, in San Diego.
Data presented at the meeting includes an updated presentation of top-line results of the open-label, single-arm, Phase 4 DUET (Develop hypersomnia Understanding by Evaluating low-sodium oxybate Treatment) trial, evaluating the effectiveness and safety of low-sodium oxybate, Xywav® (calcium, magnesium, potassium, and sodium oxybates) oral solution, on key sleep outcomes and daytime symptoms, including excessive daytime sleepiness (EDS), in adults with narcolepsy or idiopathic hypersomnia (IH). Notably, the results from DUET demonstrated statistically significant improvements from baseline to end of treatment in Epworth Sleepiness Scale (ESS) scores, reduced sleep stage shifts, increased deep sleep and reduced number of awakenings among adults with narcolepsy treated with Xywav. In adults with IH, Xywav treatment also showed improvements in ESS and Idiopathic Hypersomnia Severity Scale scores. Further, new patient-reported data from DUET demonstrated the association of Xywav treatment with improvements in daytime symptoms and functional impacts, including cognitive complaints, among adults with narcolepsy or IH. Xywav is indicated for the treatment of EDS or cataplexy in patients 7 years of age and older with narcolepsy and for adults with idiopathic hypersomnia.
“This year’s presentations at the AAN Annual Meeting reinforce our ongoing commitment to addressing debilitating neurological disorders, with limited or no treatment options including narcolepsy, idiopathic hypersomnia and epilepsy,” said Sarah Akerman, MD, head of neuroscience global medical and scientific affairs of Jazz Pharmaceuticals. “We continually strive to expand our understanding, research and capabilities in neuroscience through ongoing data generation for Xywav and Epidiolex to ensure patients’ lived experiences and needs are reflected holistically. By listening to our patients, their care teams and leading industry experts, we aim to better address the unmet needs of those living with these difficult-to-treat conditions and ultimately help redefine possibilities for their lives.”
Highlights at the 2025 AAN Annual Meeting include:
- Two presentations showcasing updated results from the open-label, single-arm, Phase 4 DUET trial of adults with narcolepsy or IH, which evaluated the effectiveness and safety of Xywav on key sleep outcomes, daytime symptoms, and functional impacts, including cognitive complaints, work productivity, and daily activities.
- Novel analysis of real-world Epidiolex® (cannabidiol) treatment patterns from U.S. specialty pharmacy data found the overall probability of persistence at one year was nearly 70% (69.9%) among new patients and underscores the importance of dose optimization. The analysis shows how healthcare providers optimize dosing over time, with half (52%) of patients taking dosages >15 mg/kg/day at 12 months and those taking an average of >20 mg/kg/day having the lowest likelihood of discontinuation. This real-world data demonstrates the importance of dose optimization for long-term persistence, which could lead to improved seizure control and tolerability.
