Narcolepsy

Data supported a positive causal association between narcolepsy and schizophrenia and a reverse causal relationship between narcolepsy and major depressive disorder.

A recent open-label study focused on vagus nerve stimulation therapy's effects on patients with narcolepsy revealed a specific and notable improvement in daytime sleepiness.

A new study revealed daytime continuous polysomnography as a reliable and easily accessible diagnostic tool for identifying narcolepsy type 1 among pediatric patients.

Subgroups of narcolepsy types 1 and 2 had significant reductions in a number of secondary outcomes, including number of sleep stage transitions, number of nocturnal arousals, and improvements in sleep quality.

Pitolisant demonstrated a dose-dependent improvement in excessive daytime sleepiness and fatigue, with a safety profile that was consistent with previous studies. Additional data to be shared in early 2024.

The findings further supported the idea that prevention and assessment of cardiovascular risk in patients with narcolepsy is critical to ongoing care.

Brendon Yee, PhD, a respiratory and sleep physician at the Woolcock Institute of Medical Research, discussed findings from a recent phase 1 trial presented at World Sleep Congress 2023 in which ALKS 2680 demonstrated improvements in wakefulness among patients with narcolepsy type 1.

Preliminary data from a phase 1 study suggest that ALKS 2680, an investigational orexin 2 receptor agonist, is safe and improves sleep latency in narcolepsy patients, leading to plans for a phase 2 study.

Modius Sleep is designed to send a safe electrical pulse into the vestibular nerve, influencing the areas of the hypothalamus and brain stem that control circadian rhythm and sleep patterns.

Presented at the 2023 World Sleep Congress, preclinical findings highlighted ORX750's potential as a novel treatment not only for narcolepsy type 1 but also for broader sleep-wake disorders, including narcolepsy type 2 and idiopathic hypersomnia.

A recent study assessing TAK-861, an orexin-type 2 receptor agonist, high and lose doses of the therapy demonstrated improvements in wakefulness compared with the placebo in healthy adult men.

A group of sleep experts discuss the importance of timely and accurate diagnosis, recent approvals, and available treatment options for managing a chronic disorder and its symptoms.

Nancy Foldvary-Schaefer, DO, FAAN, director of the Sleep Disorders Center and staff in the Epilepsy Center at Cleveland Clinic, discussed the recent advancements in narcolepsy treatments and the importance of incorporating a holistic care approach for patients.

During the open-label treatment period, 83% of patients with idiopathic hypersomnia who completed treatment saw a significant reduction in sleepiness, with an average Epworth Sleepiness Scale change of -9.4 points.

Mark I. Boulos, MD, BSc, FRCP, CSCN, MSc, associate professor of medicine, division of neurology, Institute of Medical Science, University of Toronto, talked about a comprehensive meta-analysis aimed to determine normal mean sleep latency values to accurately help clinicians with interpreting sleep test results.

The associate professor, department of medicine, division of neurology, Institute of Medical Science, University of Toronto, talked about the importance of establishing normal values for sleep studies, particularly the multiple sleep latency test, to help with effectively diagnosing sleep disorders.

Michael Grandner, PhD, associate professor of psychiatry at the University of Arizona College of Medicine, discussed Sleep Reset, an app-based, personalized sleep program that uses sleep coaches to help guide patients in the care of their sleep disorders.

Elena Koundourakis, PhD, head of orexin franchise development at Takeda, talked about the phase 2 trial investigating TAK-994 in patients with narcolepsy type 1, which showed significant improvements in wakefulness, despite discontinuation because of hepatotoxicity.

The phase 3 SYMPHONY trial assessing AXS-12, a selective norepinephrine reuptake inhibitor for narcolepsy, was initially expected in the third quarter of 2023.

In a large cohort of 848 pediatric participants with challenge-proven food allergy, investigators identified narcolepsy-like sleepiness as a symptom impacting more than 1 in 10 patients with food allergies.

In a recent multisite analysis of 361 patients with REM sleep behavior disorder, 84% had neurological abnormalities in at least one domain observed.
