A Phase 3 Study to Evaluate the Efficacy and Safety of Samelisant in Patients With Narcolepsy (AWAKE)

The primary objective of this study is to evaluate the effect of Samelisant on excessive daytime sleepiness (EDS) after 12 weeks of treatment. In addition, the study aims to assess its effectiveness in influencing the weekly frequency of cataplexy episodes (sudden bouts of muscle weakness) that occur while the individual remains conscious. Other objectives include examining the impact of Samelisant on attention and alertness, overall quality of life, the spectrum of narcolepsy symptoms, and daily functioning, as well as evaluating its safety profile.

Evaluation of Social Cognition in Patient With Type 1 or Type 2 Narcolepsy Versus Patients With Idiopathic Hypersomnia

Narcolepsy is a chronic disabling neurologic disorder mainly characterised by excessive daytime sleepiness. Type 1 narcolepsy is associated with a deficit of hypocretin in the cerebrospinal fluid responsible for the cataplexy symptom while type 2 shows a normal hypocretin level and no cataplexy. While the development of narcolepsy is independent of parental social level, narcolepsy has a significant influence on educational level, grading, social outcome, and welfare consequences. Several studies assessed global cognition efficiency, mood, and attention in narcoleptic patients but only a few specifically measured social cognition and mostly without a control group. In a population of narcoleptics children, a severe impairment in social cognition is described for 20% of the group, contrary to 2 % for the control group. The literature also depicts some impairments in decision making, somatic and cognitive emotions responses but the emotion recognition seems to be preserved. A better understanding of the social and cognitive aspects of narcolepsy could lead to a better treatment of the disease in its entirety, including if relevant specific cognitive behavioural therapy. The protocol consists in a psychometric evaluation including several questionnaires in order to assess social cognition. It will be proposed to patients with type 1 or type 2 narcolepsy and patients with idiopathic hypersomnia.

Proteomics and Metabolomics of Body Fluid in Patients With Narcolepsy

Narcolepsy (NRL) is a rare chronic central nervous system dysfunction disease, which is more common in children and adolescents, and less common in adults. Its typical clinical features include excessive daytime sleep, paroxysmal cataplexy, sleep paralysis and sleep hallucination. In addition to the above typical manifestations, patients with narcolepsy can also manifest as hyperappetite, weight gain, multiple dreams, sleep fragmentation, anxiety and depression and other emotional disorders. In particular, in narcolepsy type 1 with cataplexy, cataplexy episodes can be confused with falls caused by seizures, transient ischemic attacks or neuromuscular disorders, or even mental conversion disorders. Due to its diverse clinical symptoms, it is easy to be missed and misdiagnosed. At present, the pathogenesis of narcolepsy is still unclear, and its pathogenesis may be related to immune, genetic, environmental, infection, central nervous system degeneration and other factors. This study aims to investigate the changes of body fluid proteomics and metabolomics in patients with narcolepsy, and to provide an important basis for the pathogenesis of narcolepsy.

Decreasing Nightmares in Adults With Narcolepsy

The purpose of this clinical trial is learn whether a behavioral (non-medication) treatment can reduce nightmares in adults with narcolepsy. All participants will receive the treatment and will complete three assessments. Half of the participants will receive the treatment after the first assessment, and half will receive it after the second assessment. Romantic partners of participants with narcolepsy will also be eligible to enroll in the study. Partners will complete three assessments but will not participate in the treatment.

Unhide® Project: A Digital Health Platform to Collect Lifestyle Data for Brain Inflammation Research

The unhide® Project is a non-interventional, longitudinal research study designed to establish a secure data repository of demographic, health, and lifestyle information from individuals with brain inflammation and related neuroinflammatory conditions. Participants in the United States aged 2 years and older will provide self-reported health data, biometrics, and symptom diaries through the MyDataHelps™ app (branded as unhide® for this study). The goal is to create comprehensive longitudinal profiles to facilitate research into disease subtypes, causes, diagnostics, and potential treatments, as well as to identify potential participants for future optional studies. "Healthy" individuals without brain inflammation are also eligible to participate. The digital health research platform used in this study was originally developed and designed by Solve M.E and was called SolveTogether. The Brain Inflammation Collaborative (BIC) expanded upon Solve M.E.'s work to include related diagnoses, pediatric participants, enhance symptom tracking, and more. BIC and Solve M.E. combined Solve Together and unhide®, to create The unhide® Solve Together Unified Platform in 2025.

Genetic and Clinical Characterization of Type 1 and 2 Narcolepsy in Adult and Pediatric Black and North African Populations

Narcolepsy type 1 (NT1) is a neurological disorder characterized by excessive daytime sleepiness, cataplexy, sleep paralysis, and hallucinations while awake. It results from the loss of orexin-producing neurons in the hypothalamus, leading to a deficiency of the neuropeptide orexin/hypocretin. Studies show differences in the clinical presentation of NT1 between Caucasian and African American populations, highlighting the importance of research into genetic and clinical characteristics specific to Black and North African populations. A genetic study in these populations could identify novel genes associated with NT1 and NT2, providing crucial information for personalized diagnosis and treatment. This would fill a knowledge gap and promote more effective interventions for individuals of African descent, contributing to a better understanding of narcolepsy globally.
