Filter by: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).
This is a multicenter, open-label extension of the clinical study NLS-1021, evaluating long-term safety, tolerability, pharmacokinetics (PK), and therapeutic response to treatment with NLS-2 in adult subjects with narcolepsy.
The overall goal of this research is to test the effectiveness of a mindfulness-based intervention (MBI) for improving health-related quality of life as a complementary practice to standard care for narcolepsy. This study is a feasibility trial in which 60 adults with narcolepsy will be randomized to receive either a 4-week (brief), 8-week (standard), or 12-week (extended) MBI. Each MBI will be delivered in small groups using a live videoconferencing platform and teaches mindfulness practices to help cope with narcolepsy symptoms. By developing a scalable mind-body intervention, this project can addresses a major research gap on improving psychosocial functioning in people with narcolepsy.
For diseases that cause excessive daytime sleepiness (such as narcolepsy and idiopathic hypersomnia), there are several medications that can be used to treat sleepiness. However, it can be difficult to decide which medication to use for a particular individual for several reasons: 1) there are very few studies that directly compare two medications to see which works best; 2) there are very few studies that include people with a disorder of sleepiness called idiopathic hypersomnia. To address this gap in knowledge, the researchers propose a randomized clinical trial comparing modafinil and amphetamine salts in patients with narcolepsy type 2 or idiopathic hypersomnia. All participants will either receive modafinil or amphetamine salts - no participant will receive placebo. This study will evaluate which medication works better to improve sleepiness. The researchers will also see which medication is better for other symptoms including difficulty waking up and difficulty thinking, as well as seeing which medication causes fewer side effects. Finally, this study will see if any information about patients (such as age or sleep study features) predicts responding better to one medication or the other.
This is a randomized, placebo-controlled, double-blind, multiple cohort, fixed-dose multiple crossover, dose-finding study of oral BTD-001 in adult patients with IH or Narcolepsy without cataplexy (Type 2).
The term 'hypersomnia' describes a group of symptoms that includes severe daytime sleepiness and sleeping long periods of time (more than 10 hours per night). Sometimes, hypersomnia is caused by a problem with the quality of sleep occurring at night, for instance when nighttime sleep is disrupted by frequent breathing pauses. In other cases, however, hypersomnia occurs even when nighttime sleep is of good quality. These cases of hypersomnia are presumed to be a symptom of brain dysfunction, and so are referred to as hypersomnias of central (i.e., brain) origin, or primary hypersomnias. The causes of most of these primary hypersomnias are not known. However, our group has recently identified a problem with the major brain chemical responsible for sedation, known as GABA. In a subset of our hypersomnia patients, there is a naturally-occurring substance that causes the GABA receptor to be hyperactive. In essence, it is as though these patients are chronically medicated with Valium (or Xanax or alcohol, all substances that act through the GABA system), even though they do not take these medications. Current treatment of central hypersomnias is limited. For the fraction of cases with narcolepsy, there are FDA-approved, available treatments. However, for the remainder of patients, there are no treatments approved by the FDA. They are usually treated with medications approved for narcolepsy, but sleep experts agree that these medications are often not effective for this group of patients. Based on our understanding of the GABA abnormality in these patients, we evaluated whether flumazenil (an medication approved by the FDA for the treatment of overdose of GABA medications or the reversal of GABA-based anesthesia) would reverse the GABA abnormality in our patients. In a test tube model of this disease, flumazenil does in fact return the function of the GABA system to normal. The investigators have treated a few patients with flumazenil and most have felt that their hypersomnia symptoms improved with this treatment. To determine whether flumazenil is truly beneficial for primary hypersomnia, this study will compare flumazenil to an inactive pill (the placebo). All subjects will receive both flumazenil and the placebo at different times, and their reaction times and symptoms will be compared on these two treatments to determine if one is superior. Currently, flumazenil can only be given through an injection into a vein (i.e., intravenously). This study will evaluate this intravenous dosing as well as a new form of flumazenil, which is taken as a lozenge to be dissolved under the tongue. If this study shows that flumazenil is more effective than placebo in the treatment of hypersomnia, it will identify a potential new therapy for this difficult-to-treat disorder.
