Avadel Pharmaceuticals Celebrates Key Court Ruling for LUMRYZ

Avadel Pharmaceuticals Achieves Milestone in LUMRYZ Approval
DUBLIN, June 30, 2025 — Avadel Pharmaceuticals plc (Nasdaq: AVDL), a leading biopharmaceutical company committed to transforming patient care through innovative medicines, has announced that the U.S. Court of Appeals for the District of Columbia Circuit upheld the FDA's approval of LUMRYZ, a groundbreaking treatment for narcolepsy.
Impact of the Appeals Court Decision
The unanimous decision by the Appeals Court affirms a previous ruling by the District Court favoring the FDA in a legal challenge posed by Jazz Pharmaceuticals Inc. regarding the FDA’s approval of LUMRYZ™. This ruling signifies a major validation for the innovative formulation of LUMRYZ, the first and only oxybate treatment to be taken once at bedtime for individuals aged 7 and older suffering from narcolepsy.
CEO's Comments on the Decision
Greg Divis, the CEO of Avadel Pharmaceuticals, expressed his satisfaction with the ruling, emphasizing that it underscores LUMRYZ's clinical superiority and its critical role in enhancing patient care. He stated, "This decision not only affirms the FDA's approval but also highlights the distinct advantages of LUMRYZ’s dosing regimen, which is designed to improve the quality of life for those living with narcolepsy."
The Advantages of LUMRYZ
LUMRYZ is designed as a once-at-bedtime treatment option that allows patients to experience uninterrupted sleep. This innovative therapy could change the landscape of treatment for individuals with narcolepsy, offering them the possibility of having a consistence and effective management of their condition. With over thousands currently benefiting from LUMRYZ, Avadel aims to extend this life-enhancing treatment to even more patients.
Historical Context of the Approval
Following the initial support from the District Court in late 2024, which favored the FDA's position, Jazz Pharmaceutical's appeal led to this ultimate decision by the Appeals Court. This ruling is significant as it not only maintains LUMRYZ’s market presence but also reinforces the regulatory confidence in the product's safety and efficacy.
Understanding LUMRYZ
Approved by the FDA in May 2023, LUMRYZ is vital for treating cataplexy and excessive daytime sleepiness (EDS) in pediatric and adult patients aged 7 years and above who have been diagnosed with narcolepsy. The approval was substantially backed by the REST-ON™ study, a rigorous Phase 3 trial that showcased significant benefits.
Safety and Use of LUMRYZ
As with all medications, LUMRYZ does come with safety information that patients need to be aware of. Importantly, LUMRYZ should not be combined with other central nervous system depressants, as this combination can lead to severe respiratory and cardiovascular complications.
