27 Clinical Trials for Various Conditions
This study is of an investigational drug called SUVN-G3031 (Samelisant) as a possible treatment for narcolepsy with cataplexy or narcolepsy without cataplexy. The main purpose of this study is to learn how well the study drug works and how safe the study drug is compared to placebo.
Narcolepsy
CONCERT (Clinical Outcomes in Narcolepsy and Cataplexy: An Evaluation of Reboxetine Treatment) is a Phase 2, double-blind, randomized, placebo-controlled, crossover, multicenter trial of AXS-12 in patients with narcolepsy. Subjects meeting the entry criteria will be randomized in a 1:1 ratio either to placebo for three weeks followed by AXS-12 (up to 10 mg daily) for three weeks, or to AXS-12 (up to 10 mg daily) for three weeks followed by placebo for three weeks. Efficacy assessments will include the frequency of cataplexy attacks, and measures of other symptoms of narcolepsy.
Narcolepsy, Cataplexy Narcolepsy, Excessive Sleepiness
The purpose of this study is to determine whether once-nightly FT218 is safe and effective for the treatment of excessive daytime sleepiness and cataplexy in subjects with narcolepsy.
Excessive Daytime Sleepiness, Cataplexy, Narcolepsy
Narcolepsy without cataplexy or Narcolepsy Type 2 (NT2) is a lifelong condition that makes people very sleepy during the day, regardless of how much sleep they get at night. People with NT2 may fall asleep suddenly, have trouble staying awake during the day, or may not be able to sleep well at night. They may have difficulty thinking clearly, paying attention, or remembering things, during the day. These symptoms can make daily activities like driving, working, or caring for their families challenging, impacting their quality of life. Orexin is a chemical made in the brain that helps keep a person awake and alert. TAK-360 acts like orexin. Previous studies have shown that medicines that act like orexin may keep people awake. The main aim of this study is to learn how safe TAK-360 is and how well adults with NT2 tolerate it. Researchers also want to find out if TAK-360 can help people with NT2 stay awake and determine the right dosage needed to do that. Participants will be randomly (by chance, like drawing names from a hat) assigned to get either TAK-360 or placebo in the treatment period. The placebo is a pill that looks just like TAK-360 but does not have any medicine in it. Using a placebo helps researchers learn about the real effect of the treatment.
Narcolepsy Type 2
This is a study to determine the effect of multiple doses of an investigational drug, taken by mouth, in people with Narcolepsy-cataplexy.
Narcolepsy
This EAP will be open to provide access to treatment with pitolisant while a U.S. New Drug Application (NDA) is being prepared and submitted for review for marketing approval.

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.

Narcolepsy, Excessive Daytime Sleepiness, Cataplexy 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.
Idiopathic Hypersomnia, Narcolepsy Without Cataplexy
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).
Idiopathic Hypersomnia, Narcolepsy Without Cataplexy
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.

The initial portion of the protocol involves discontinuing any medications for cataplexy that the patient may be taking. Subsequently, the patient is prescribed a dose of oral solution of study drug or placebo over a 10-11 week period. During the trial, narcolepsy symptoms will be evaluated. Participants are allowed to continue using stimulant medications at constant doses during the study. A total of 1 to 3 daytime visits in addition to 4 overnight visits to the sleep center will be required to complete the study.
