This study is a long-term follow-up for people with narcolepsy or idiopathic hypersomnia who previously took the experimental drug ORX750. Researchers want to see if the drug remains safe and effective over time. About 90 participants will take ORX750 orally and be monitored for …

This study tests an experimental drug called cleminorexton in 222 adults with narcolepsy type 1 or 2. The drug mimics a natural brain protein that helps keep people awake. The goal is to see if it safely reduces daytime sleepiness and improves daily functioning. Participants must…

This study tests a drug called samelisant in 240 people with narcolepsy (with or without cataplexy). The goal is to see if it reduces excessive daytime sleepiness and sudden muscle weakness episodes over 12 weeks. Participants will take the drug or a placebo and report their slee…

This phase 3 trial tests whether a daily tablet called ALKS 2680 can reduce daytime sleepiness and cataplexy (sudden muscle weakness) in 150 adults with narcolepsy type 1. Participants will take the drug or a placebo for 12 weeks, and researchers will measure changes in sleep tes…

This Phase 3 study tests whether expanded dosing regimens of Xywav can safely reduce excessive daytime sleepiness in adults with narcolepsy or idiopathic hypersomnia. About 108 participants will receive either Xywav or a placebo in a randomized withdrawal design. The main goal is…

This early-stage trial is testing a new drug called Lu AH69593 to see if it is safe and how the body handles it. The study includes healthy volunteers and people with narcolepsy. Researchers will monitor side effects and measure drug levels in the blood, including how food affect…

This study is testing the long-term safety and how well ALKS 2680 works over time in people with narcolepsy type 1, type 2, or idiopathic hypersomnia. Participants take a once-daily tablet at different doses. The goal is to see if the drug remains safe and effective for staying a…

This study tests a non-medication therapy called Imagery Rehearsal Therapy to see if it can reduce nightmares in adults with narcolepsy. About 80 participants will receive the therapy and complete three assessments, with half starting right away and half later. The goal is to imp…

This study tests a new drug, TAK-360, for adults with narcolepsy type 1, a condition causing severe daytime sleepiness and sudden muscle weakness (cataplexy). About 92 participants will receive either TAK-360 or a placebo to see if the drug is safe and well-tolerated. Participant…

This study tests whether E2086, an oral tablet, can reduce excessive daytime sleepiness in adults with narcolepsy. About 64 participants will receive either the drug or a placebo for 4 weeks. Researchers will measure how long people can stay awake using a standard test, and also …

This study tests a new extended-release version of sodium oxybate taken as a single dose at bedtime for children with narcolepsy type 1. Researchers want to see if kids prefer it over current twice-nightly options and if it is safe and convenient. About 36 children from Stanford …

This study tracks pregnant women with narcolepsy who take pitolisant (Wakix) or other narcolepsy medications, as well as pregnant women without narcolepsy who take pitolisant. Researchers compare pregnancy outcomes, including birth defects, to see if the drug poses risks. The goa…

This study looks at how narcolepsy (types 1 and 2) and idiopathic hypersomnia affect social cognition—skills like recognizing emotions and making decisions. Researchers will give 75 adults several questionnaires to measure attention, impulse control, empathy, and emotion recognit…

This study looks at proteins and metabolites in the body fluids of 60 people with narcolepsy, a rare sleep disorder. The goal is to find biological markers that could explain what causes the condition and help doctors diagnose it more accurately. Participants provide samples for …

This research study collects health information from 10,000 people with brain inflammation conditions like Long COVID, ME/CFS, and autoimmune diseases. Participants use a smartphone app to share symptoms, health history, and wearable data. The goal is to find disease subtypes and…
