Active clinical trials for "Narcolepsy"

The main aim of this study is to see how TAK-861 works on symptoms of narcolepsy, including excessive daytime sleepiness and cataplexy. Approximately 100 participants will take part in the study across North America, Europe and Asia Pacific. The treatment (TAK-861 or placebo) will be administered for 8 or 12 weeks. After this treatment period the participant will have the option to participate in a separate, long- term extension study during which all participants will be treated with TAK-861.

The main aim is to evaluate the effect of TAK-861 on symptoms of narcolepsy, including excessive daytime sleepiness (EDS) as measured by sleep latency from the Maintenance of Wakefulness Test (MWT). The study will enroll approximately 60 participants and they will be randomly assigned to 3 groups (20 per group) to take one of two different doses of TAK-861 or a placebo. All the participants will receive the treatment for 8 weeks. Participants will be asked to complete some questionnaires during the study. This trial will be conducted in North America, Europe, and Asia Pacific.

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 is a multi-center, double-blind, placebo-controlled, randomized Phase 3 trial to assess the safety and efficacy of AXS-12 in narcoleptic subjects with cataplexy and excessive daytime sleepiness (EDS).

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 goal of this clinical trial is to test two behavioral treatments for nightmares in adults with narcolepsy. The main questions it aims to answer are: Is imagery rehearsal therapy (IRT) effective for narcolepsy-related nightmares? Does adding targeted dream control (TDC) to IRT make it more effective? Participants will be randomized to one of two treatment groups and will be asked to: Complete a daily log of sleep symptoms for up to 13 weeks. Attend 7 sessions of treatment. Complete questionnaires before and after treatment. Go to the research lab in Evanston, IL to complete a sleep study during a daytime nap (Chicago area residents only).

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).

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.

This study will evaluate the long-term efficacy and safety of AXS-12 in narcoleptic subjects with cataplexy and excessive daytime sleepiness (EDS).

The purpose of this study is to evaluate a medication called clarithromycin for treating sleepiness in narcolepsy and idiopathic hypersomnia. Studies have shown that clarithromycin can reduce sleepiness, but researchers do not know how clarithromycin does this. This study will look at brain activity (on magnetic resonance imaging [MRI]), inflammation, bacteria living in the gut, and cerebrospinal fluid, to better understand how clarithromycin can reduce sleepiness. This study will recruit 92 participants who will be randomized to receive clarithromycin or a placebo for 14 days.
