Active clinical trials for "Disorders of Excessive Somnolence"

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.

The primary objective of the study is to determine whether armodafinil treatment is more effective than placebo treatment in patients with excessive sleepiness associated with shift work disorder (SWD) by measuring improved clinical condition late in the shift, including the commute home.

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. The causes of most of these central 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 clarithromycin (an antibiotic approved by the FDA for the treatment of infections) would reverse the GABA abnormality. In a test tube model of this disease, clarithromycin does in fact return the function of the GABA system to normal. The investigators have treated a few patients with clarithromycin and most have felt that their hypersomnia symptoms improved with this treatment. To determine whether clarithromycin is truly beneficial for central hypersomnia, this study will compare clarithromycin to an inactive pill (the placebo). All subjects will receive both clarithromycin 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. If this study shows that clarithromycin is more effective than placebo in the treatment of hypersomnia, it will identify a potential new therapy for this difficult-to-treat disorder.

Multicenter randomized double blind study versus placebo during 12 weeks with at first, an escalating dose period followed by stable dose period at the selected dose. This double-blind period can be followed by a 9 months open-label period if the patient wishes to continue with the study product.

The purpose of this study is to determine whether a compound known as EVT 201 is effective in treating elderly patients diagnosed with primary insomnia who also have moderate daytime sleepiness.

Many patients with Parkinson's disease (PD) have sleep problems, including excessive sleepiness during the day. This is probably due to degeneration of sleep-regulating areas in the brain. At present, the only treatment for sleepiness in PD is modafinil, which is expensive and only partially effective. There is another potential treatment for sleepiness that is used worldwide, is inexpensive, well tolerated and safe - namely, caffeine. There have also been suggestions that caffeine may slow the progression of degeneration in PD, since coffee non-drinkers are at higher risk of developing PD. PD patients, even with severe sleepiness often do not use caffeine. It is unclear whether this is because their PD makes their sleepiness unresponsive to caffeine, because they cannot tolerate it, or whether this reflects their lifelong habit of non-use. This proposal outlines a trial in which patients with excessive sleepiness will be given caffeine or placebo (no therapy) in a blinded fashion. In this way, the effect of caffeine on sleepiness and motor symptoms can be directly analyzed. In addition, these findings can be used to test the tolerability of caffeine, to help plan a larger-scale study testing whether caffeine can slow the progression of PD

This is a study of the efficacy and safety of JZP-258, an oxybate mixed-salts oral solution being developed as a low sodium alternative product for Xyrem.

The purpose of this study is to evaluate the safety and tolerability of administering a single intravenous (IV) infusion dose of TAK-925 to adults with obstructive sleep apnea (OSA) who are experiencing excessive daytime sleepiness (EDS) despite adequate use of CPAP as the primary OSA therapy.

The purpose of study JZP110-401 is to evaluate solriamfetol pharmacokinetics (PK) in the breast milk and plasma of healthy postpartum women following the administration of the drug. The study also aims to estimate the potential daily solriamfetol dose received by the infant from the breast milk of the nursing mother. The safety and tolerability of single oral doses of solriamfetol will also be assessed.

The aim of this study was to analyze the effects of strength training on sleep quality and daytime sleepiness in institutionalized adolescents (14 to 19 years of age). Thirty-one adolescents were randomly assigned in two sample groups: intervention group (IG, n = 19) and control group (CG, n = 12). Anthropometric measures were performed (height and body mass) and BMI was determined. Sleep quality and daytime sleepiness were assessed using the questionnaires, Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESE), and total sleep time by accelerometer. Physical training (2x / week) was performed for 12 weeks. The OMNI Perceived Exertion Scale for Resistance Exercise (OMNI-RES) scale was used to control the effort intensity and the exercises followed an alternate pre-follow-up.
