Filter by:This study is to evaluate the pharmacokinetics, pharmacodynamics, and safety of single and multiple doses of armodafinil (50, 100, and 150 mg/day) in children and adolescents with excessive sleepiness associated with narcolepsy.
This is a study to evaluate the safety and effectiveness of ADX-N05 compared to placebo in the treatment of excessive daytime sleepiness in adults with narcolepsy.
Study objectives are to determine the efficacy, safety and tolerability of bright light treatment in Parkinson's Disease (PD) patients with daytime sleepiness. Thirty PD patients will be enrolled and equally randomized to bright light or dim-red light treatment. Objective (actigraphy) and subjective (sleep logs/scales) sleep measures will be collected through the baseline and intervention phases of the study. The primary outcome measure will be the change in the Epworth Sleepiness Scale (ESS) comparing the bright light treatment with dim-red light treatment. Secondary outcome measures will include the Multiple Sleep Latency Test (MSLT), global Pittsburgh Sleep Quality Index (PSQI) score, Parkinson's Disease Sleep Scale (PDSS) score, and actigraphy measures. A variety of exploratory analyses will examine the effects of bright light treatment on fatigue, depression, quality of life, cognition, and motor disability. Hypothesis: Bright light exposure will diminish daytime sleepiness and improve night-time sleep in PD patients with daytime sleepiness.
There are over 2 million breast cancer survivors today. Persistent Cancer-Related fatigue (PCRF), a state of being tired or weary, is one of the most common and distressing symptoms experienced by breast cancer (BC) survivors. Rates of significant PCRF in BC survivors range from 30% to 82% within the first 5-years of diagnosis and there are few treatment options for PCRF and these treatments require the availability of a trained practitioner, are associated with significant costs, pose a sizeable burden for the patient, or have unacceptable side-effects. Acupressure is a technique derived from acupuncture, a component of Traditional Chinese Medicine. In acupressure, physical pressure is applied to acupuncture points by the hand, elbow, or with various devices to treat disease. Pilot studies have demonstrated that self-administered acupressure can significantly decrease PCRF by as much as 70% in cancer survivors. Acupressure can also have positive effects on sleep quality in cancer patients and other chronically ill populations. Self-administered acupressure is a non-toxic and inexpensive treatment that requires minimal instruction. It also requires little effort and time on the part of the patient to successfully complete. Thus, acupressure appears to be a promising treatment for PCRF and associated symptoms. The investigators are conducting a single-blind, placebo controlled study to examine the specific effect of two opposing acupressure treatments compared to standard of care. The goal of this study is to determine the benefit of acupressure on treating persistent fatigue experience by many patients after completing their cancer treatment. Study patients will be randomized into one of three groups: two different types of acupressure or a standard of care arm. For those participants randomized to receive acupressure, the technique will be taught to them by a study nurse trained by an acupressure specialist. Participants will be asked to perform the acupressure daily over the next six weeks, during which time they will record their fatigue and be asked to wear an activity monitor to have their daily activity levels monitored.
Patients with Obstructive Sleep Apnea Syndrome (OSAS) will evidence higher levels of salivary cortisol and alpha-amylase levels prior to use of placebo and continuous positive airway pressure (CPAP) and will evidence a decrease in these levels after consistent use of continuous positive airway pressure (CPAP) therapy as compared to placebo. Their level of sleepiness will also decrease with the use of CPAP therapy and will correlate with the levels of salivary cortisol and alpha-amylase in relation to their subjective sleepiness scale, Psychomotor Vigilance Test (PVT), and pupillometry.
Sleep deprivation induces degradation of night-time driving ability via sleepiness. Because of conflicts between physiological needs and social or professional activities, it is necessary to develop affordable countermeasure to sleepiness. In real-life driving studies, nap and coffee are efficient countermeasures of sleepiness at the wheel. However the effect of caffeine is quick but brief and varies between individuals. There is a need for more knowledge in order to know what to recommend to drivers. Exposure to 460-nm monochromatic light (blue light) decreases subjective sleepiness and improves performances. One objective of this project is to investigate whether blue light exposure during driving would be useful in a real driving situation when sleepiness becomes acute. Owing to the fact that our knowledge of the effects of exercise on driving is very sparse and to the absolutely need to standardize the bouts of exercise that will be applied to the subjects. One objective of the present study will be to investigate in a simulator study the effects of a bout of moderate exercise on participants driving ability when sleepiness becomes acute. Nocturnal neurobehavioral performance varies widely between individuals and only certain subjects seem significantly affected by sleep loss. It is of interest to find biological markers for sleep drive to identify vulnerable drivers to sleep deprivation or to identify responders to sleepiness countermeasures (i.e., coffee and blue light). One objective of this study is to determine individual differences (genetic, hormonal and cognitive) in the impairment of driving skills induced by sleep loss and in the efficiency of countermeasures (blue light and coffee).
The primary objective of this study is to evaluate the safety and tolerability of long-term (12 months) armodafinil treatment in patients with excessive sleepiness associated with mild or moderate closed traumatic brain injury (TBI).
This research project consists of a three part study with five embedded sub studies. The first study phase identifies "body rhythms" of sleepiness/wakefulness and of melatonin levels for each subject (including sub-study 1). The second study phase identifies the optimum dose and timing of melatonin for regulating each individual's 24-hour sleep/waking cycle (including sub-study 2). The third study phase introduces a new independent variable, light (including sub-studies 3 and 4). Sub-study 5 is an optional longitudinal study. Sub-study 1 looks at how keeping a regular sleep schedule affects the body's natural rhythm. Sub-study 2 looks at how individuals metabolize melatonin. Sub-study 3 tests how individuals' endogenous melatonin production responds to bright outdoor light and Sub-study 4 tests a previous finding that artificial bright light exposed daily behind the knee can regulate the body clock. Sub-study 5 is an optional longitudinal study, an extension of the first study stage, for subjects whose rhythms are not clearly free-running.
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 mild or moderate closed traumatic brain injury (TBI).
This clinical trial is designed to evaluate the safety and potential efficacy of Xyrem for the treatment of excessive daytime sleepiness (EDS) and nocturnal sleep disturbance in patients with mild to moderate Parkinson's Disease (PD).
