Filter by:The purpose of this research study is to assess the safety and efficacy of ALKS 2680 compared to placebo, including whether participants taking ALKS 2680 experience a greater decrease in sleepiness and a decrease in cataplexy ("sudden loss of muscle control"), compared to participants taking placebo alone.
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.
The goal of this study is to test a web-based psychoeducational resource for adolescents with central disorders of hypersomnolence and their families. The investigators hope to assess the website's usability, acceptability, and feasibility, as well as its potential effect on social relationship health. Participants will be asked to review the content of the psychoeducational websites. The participants will then provide feedback on the website, as well as the adolescent's social relationships and social health before and after reviewing the website through online surveys.
The purpose of this study is to evaluate the safety, efficacy, pharmacokinetics (PK), and pharmacodynamics (PD) of MK-6552 in participants with Narcolepsy Type 1 (NT1). Part 1 will evaluate safety, tolerability, and PK of MK-6552 after administration of ascending doses in a single day to support a dose level decision for Part 2. Part 2 will investigate the PD of MK-6552 after single-day and multiple-day administration. Participants who complete Part 1 and demonstrate that they are able to tolerate at least one dose level of MK-6552 will participate in Part 2.
This study is part of the research on type 1 narcolepsy, a neurological pathology affecting mostly young subjects. The only biomarker currently available is the hypocretin assay, which shows a level below 110 pg/mL. However, the interpretation of this biomarker has limitations: the test is not widely available and it is rarely performed by practitioners. Even when performed, the interpretation of the level may not be consistent with the phenotype compatible with type 1 narcolepsy. This study therefore aims to develop new tools to reduce the diagnostic delay. This would be the first study with 7T MRI that could achieve a level of spatial resolution sufficient to highlight volume changes in small brain structures such as the lateral hypothalamus whose narcolepsy-induced changes are not detected by lower resolution MRI.
Narcolepsy is a chronic brain disorder. The mechanism is the impairment of brain controlling of sleep and wakefulness. The cause of this disease is still unclear, but common symptoms include excessive day time sleepiness, cataplexy, hypnogogic hallucination, sleep paralysis, and sleep disturbance. Because these symptoms are easily confused together in many situations, it is difficult for doctors to make the diagnosis. Therefore, medical treatment for patients is always delayed. According to previous research report, narcoleptic patients are often delay diagnosis for 10 to 15 years after the onset of the disease. Clearly, to make the diagnosis of narcolepsy is very difficult. Another cause for the delay is the method for diagnosing narcolepsy, which mainly rely on sleep examination instruments and the testing of hypocretin concentration in the cerebrospinal fluid. However, these tests are difficult to carry out in many areas, and diagnosing narcolepsy is still difficult in many countries. To the patients and their families, developing a fast and accurate method or tool for diagnosing narcolepsy is of the utmost importance.
This study will assess the safety and efficacy of JZP258 (XYWAV) on sleepiness, polysomnography, and functional outcomes in patients with idiopathic hypersomnia (IH) or narcolepsy.
The aim of this study is to quantify the change in blood pressure when participants with narcolepsy treated with high-sodium oxybate are transitioned to XYWAV, a low-sodium oxybate. The results of this study may provide health care providers (HCPs), patients, and payers with important new information regarding BP changes related to differences in sodium content between available oxybates for the treatment of narcolepsy.
The main aim is to evaluate the safety and tolerability of TAK-861 on participants with type 1 and type 2 narcolepsy from previous parent studies, TAK-861-2001 (NCT05687903) and TAK-861-2002 (NCT05687916).
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.
