Active clinical trials for "Narcolepsy"

A significant weight gain and obesity are observed for most patients with narcolepsy, mainly at the beginning of the disease and narcolepsy in young children. There is no specific study on the population and the consequences of overweight in the lives of these long-term patients. Narcoleptic patients gain weight significantly at the onset of their illness. It is also known that weight gain is not related to the treatment of narcolepsy. The etiology of obesity in narcoleptic patients is not established. Several assumptions were made (physical activity, leptin diet, metabolism). The reason and the pathophysiology of overweight and obesity in this population therefore remain unclear. In this study, potential change in the total metabolism (24h) for narcoleptic children that could explain their tendency to obesity will be assessed ?

15 patients with narcolepsy and 15 healthy controls will be included in the study. According to a randomized, double-blind protocol they will receive intranasally at night first Orexine A and approximately two weeks later placebo or vice versa. Thereafter sleep will be recorded, the cytokine-system and neurocognition characterized.

Type 1 narcolepsy (NT1) is a chronic sleep disorder caused by the selective and irreversible loss of neurons from the hypothalamus, which synthesizes a neurotransmitter: hypocretin (Hcrt) / orexin. The exact cause of this destruction is still unknown, but the autoimmune hypothesis is strongly favored, involving the interaction of genetic and environmental factors. The treatment of NT1 is currently only symptomatic, targeting hypersomnolence and cataplexy. To prevent the destruction of Hcrt neurons, immunomodulatory agents have been tested, with varying efficacy, probably due to varying degrees of hypothalamic impairment and stages of disease progression. During microglial activation, a condition associated with neuroinflammation in the brain, there is an increase in the mitochondrial translocation protein (TSPO), which can be quantified in vivo by specific tracers, such as the [18F] DPA- 714, in positron emission tomography (PET), a very sensitive nuclear imaging technique. The aim here is to study microglial activation in PET [18F] DPA-714 in NT1 patients with recent evolution in comparison with controls; then analyze the effect of age, and the severity of symptoms on this PET imaging biomarker. The hypothesis is that microglial activation, especially of the hypothalamic region, is greater in NT1 than controls.

The overall aim of the study is to investigate the effect of a new, non-pharmacological method that may alleviate the symptoms of narcolepsy and thereby lead to a reduction in the use of medications with potentially serious side effects in patients with this disease.

Nexus is a collaboration between academic institutions, advocacy and industry to answer important questions about narcolepsy. It is a web-based observational study of patient-reported outcomes in adult patients with narcolepsy, with follow-up every six months. Nexus website: www.narcolepsyregistry.com

The rationale for the patient-centric, prospective, observational, non-interventional study design of JZP258-402 is to evaluate the transition experience of participants with narcolepsy treated with oxybate and to examine the impact of transitioning from Xyrem to Xywav in a real-world setting.

The aim of this study is to describe and compare the anaesthesia history and possible problems encountered in 3 groups of patients with 3 chronic sleep diseases: narcolepsy, idiopathic hypersomnia, and restless legs syndrome followed at the Montpellier Sleep Unit. For each participant, existing data from the medical record will be used, with their consent. All participants will complete a standardized questionnaire, concerning their history of anaesthesia, the course and possible complications, and questions about their treatment for their sleep disorder.

Up to 50% of Narcolepsy-cataplexy (NC) patients suffer from REM sleep behavior disorder (RBD), a parasomnia. A strong link was found between RBD and impulse control disorders (ICD) in Parkinson disease (PD) patients. ICD are thought to be related to a dysfunction of meso-cortico-limbic pathways which belong to the so called ''reward system''. A recent study in IRMf shows that RBD is associated with impaired reward system. A strong link was found between these two disorders and therefore we believe that RBD is associated with impaired reward system in NC The main objective of this study is to evaluate differences in brain activation between NC patients with and without RBD. The investigators hypothesize that NC patients with RBD have a more severe dysfunction of the reward system (hypoactivation of the meso-cortico-limbic pathway) than patients without RBD.

Narcolepsy is a chronic, disabling, and rare sleep disorder (prevalence 1/2500) characterized by excessive daytime sleepiness and, in some patients, falls in muscle tone related to emotions (cataplexies). It often begins in childhood or in young adults. Symptoms of narcolepsy are responsible for an important handicap in everyday life, and are often misunderstood by the family and professional environment. In addition, many comorbidities are associated with narcolepsy, such as depression, anxiety, or obesity. Few studies have investigated the impact of narcolepsy on patients' academic background, socio-professional integration, and quality of life. Narcoleptic patients may experience more difficulties in their academic and professional path than non-narcoleptic people. These difficulties would be multifactorial (related to the disease itself, comorbidities, external factors ...). As a better understanding of these determinants could help to inform patients and guide them in their choices, this study propose to establish a comprehensive inventory of educational and professional trajectories of narcoleptic patients in France in order assess the specificity of the difficulties encountered by the people concerned in their life course and to appreciate the attitude of the academic and professional circle with respect to the disease. This category 3 study (according to the French law "Loi Jardé") is based on the case-control model and will be conducted in all National Reference and Competence Centers for Narcolepsy and Hypersomnia. It will include a population of adult and paediatric patients. It will answer questions about work and schooling in these patients.

Autonomic nervous system dysfunction has been described in narcolepsy with cataplexy affecting the sympathetic function. In this study the investigators analyzed whether altered diurnal and nocturnal cardiovascular control is present in idiopathic hypersomnia. Drug-free patients diagnosed with idiopathic hypersomnia and age-matched controls were included. Clinical data, 24-h polysomnography, heart rate variability and the heart rate response to spontaneous arousal are analyzed.
