DUBLIN, Ireland, Nov. 12, 2024 (GLOBE NEWSWIRE) -- Avadel Pharmaceuticals plc (Nasdaq: AVDL), a biopharmaceutical company focused on transforming medicines to transform lives, today provided a corporate update and announced its financial results for the quarter ended September 30, 2024.

"Over a year ago, we set out on our mission to transform the lives of those living with narcolepsy, including expanding the oxybate market through the introduction of LUMRYZ. This quarter, we are proud to see that expansion come to fruition and continue to be encouraged by patient uptake and quarter-over-quarter growth of LUMRYZ. In parallel to our launch in adults with narcolepsy, we are expanding into additional patient populations, starting with the recent FDA approval of LUMRYZ for the treatment of cataplexy or EDS in patients 7 years and older with narcolepsy, significantly alleviating the burden on patients and their caregivers of waking up in the middle of the night to administer treatment,” stated Greg Divis, Chief Executive Officer of Avadel Pharmaceuticals. "We are also pleased with the recent court ruling affirming FDA's determination that LUMRYZ, dosed once at bedtime, demonstrates clinical superiority to twice-nightly oxybates, which mitigates an important legal and business risk for the company. With our Phase 3 pivotal trial in IH ongoing, our continued execution of the LUMRYZ launch including our expansion of LUMRYZ into pediatric narcolepsy, we are closing in our business objectives of being a leader in the sleep field and fulfilling the promise of LUMRYZ for all stakeholders.”

About LUMRYZ™ (sodium oxybate) for extended-release oral suspension

LUMRYZ is an extended-release sodium oxybate medication approved by the FDA on May 1, 2023, as the first and only once-at-bedtime treatment for cataplexy or excessive daytime sleepiness (EDS) in adults with narcolepsy. On October 16, 2024, LUMRYZ was additionally approved as a once-at-bedtime treatment for cataplexy or EDS in patients 7 years and older with narcolepsy.

The FDA approval of LUMRYZ was supported by results from REST-ON, a randomized, double-blind, placebo-controlled, pivotal Phase 3 trial in adults with narcolepsy. LUMRYZ demonstrated statistically significant and clinically meaningful improvements in the three co-primary endpoints: EDS (MWT), clinicians' overall assessment of patients' functioning (CGI-I), and cataplexy attacks, for all three evaluated doses when compared to placebo.  

With its approval in May 2023 and in October 2024, the FDA also granted 7 years of Orphan Drug Exclusivity to LUMRYZ for the treatment of cataplexy or EDS in adults with narcolepsy and pediatric patients 7 years and older with narcolepsy (respectively) due to a finding of clinical superiority of LUMRYZ relative to currently available oxybate treatments. In particular, the FDA found that LUMRYZ makes a major contribution to patient care over currently available, twice-nightly oxybate products by providing a once-nightly dosing regimen that avoids nocturnal arousal to take a second dose.

Falling asleep quickly, including while standing or while getting up from the bed, has led to falls with injuries that have required some people to be hospitalized.

LUMRYZ can cause serious side effects, including the following:

• Sleepwalking. Sleepwalking can cause injuries. Call your doctor if you or your child start sleepwalking.

The most common side effects of LUMRYZ in adults include nausea, dizziness, bedwetting, headache and vomiting. Your side effects may increase when you take higher doses of LUMRYZ. The most common side effects in children include nausea, bedwetting, vomiting, headache, decreased weight, decreased appetite, dizziness, and sleepwalking.
