NCT07502443
The purpose of this study is to measure decreases in daytime sleepiness, and disease symptoms in participants with Narcolepsy Type 2 (NT2) when taking ALKS 2680 tablets compared with placebo tablets.
NCT07299097
The main purpose of this study is to find out how many people in Spain have been diagnosed with narcolepsy type 1 and type 2, and how many new participants are diagnosed each year. Narcolepsy is a rare sleep disorder that causes excessive daytime sleepiness. The researchers will look at medical records from hospitals across Spain to count participants with these conditions and understand patterns in diagnosis over time.
NCT06251063
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.
NCT06767683
The purpose of this study is to continue to measure the safety, tolerability, and durability of treatment effect in subjects with Narcolepsy Type 1 (NT1), Narcolepsy Type 2 (NT2), or Idiopathic Hypersomnia (IH) when taking ALKS 2680 tablets.
NCT06555783
The purpose of this study is to measure the safety and decrease in sleepiness in subjects with narcolepsy type 2 (NT2) when taking ALKS 2680 tablets compared to placebo tablets.
NCT06952699
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.
NCT05687916
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.
NCT04096560
The main aims of the study are: * To check for side effects from TAK-994 and check what dose of TAK-994 participants can tolerate. * To check what dose range provides adequate relief of narcolepsy symptoms. * To check how much TAK-994 stays in the blood of participants, over time. The study will have 4 parts. Participants can only join 1 of the parts. A. Participants with type 1 narcolepsy will take either TAK-994 or placebo tablets for 28 days. A placebo looks just like TAK-994 but will not have any medicine in it. B. Participants with type 1 narcolepsy will take 1 of 3 doses of TAK-994 or placebo tablets for 56 days. C. Participants with type 1 narcolepsy in China only will take TAK-994 or placebo tablets for 56 days. D. Participants with type 2 narcolepsy will take either TAK-994 or placebo tablets for 28 days.
