This research is being done to figure out whether treatment for sleep apnea, in people who have had a stroke or TIA, improves recovery from stroke, and helps prevent future stroke, heart problems, and death.
The intervention being tested is called continuous positive airway pressure (CPAP). The U.S. Food and Drug Administration (FDA) has approved CPAP for the treatment of obstructive sleep apnea.
A total of 15,010 patients are expected to enroll in this study and be screened for sleep apnea across about 110 sites in the United States. About 3,000 are expected to participate in the second part of the study, in which sleep apnea treatment is tested. Participation in this study is approximately 6 months.
The study is designed to look at the usefulness and safety of an oxybate mixed-salts oral solution or placebo for treatment of Idiopathic Hypersomnia. Idiopathic Hypersomnia (IH) is a sleep disorder in which a person is excessively sleepy during the day and has great difficulty being awakened from sleep. Study staff nor participants will know if they are receiving study drug or placebo. Participants will be male or female subjects 18-70 years old with a diagnosis of Idiopathic Hypersomnia (IH) within the last five years, and not due to other medical conditions such as Narcolepsy, restless leg syndrome, and uncontrolled hypothyroidism. A minimum of 140 study subjects will be randomized across all sites with 72 randomized to the study drug and 72 to the placebo drug. The study treatment period from screening to follow-up will last approximately 42 weeks, requiring nine visits. An overnight stay might be required to confirm the diagnosis of IH.
The study is designed to assess the efficiency and safety of a once nightly formulation of sodium oxybate for extended-release oral suspension or a placebo for the treatment of excessive daytime sleepiness and cataplexy, sudden and uncontrollable muscle weakness or paralysis, in subjects with narcolepsy. Study staff nor participants will know if they are receiving study drug or placebo. Participants will be male or female subjects 18 years of age or older. A total of 264 study subjects will be randomized across all sites with 132 randomized to the study drug and 132 to the placebo drug. The study treatment period from screening to follow-up will last approximately 17 weeks. Requiring 9 visits with 4 overnight stays.
Sleep disturbance, particularly insomnia, is a common problem for cancer survivors. Insomnia can be described as excessive daytime napping, difficulty falling asleep, difficulty staying asleep, or waking up earlier than you would like. Insomnia can increase fatigue, impair physical function, impair immune function, cause circadian rhythms (known as your biological clock) to be disrupted and decrease quality of life. Because there is no ideal standard of care for effectively treating sleep problems in cancer survivors, the purpose of this study is to compare the effectiveness of three different treatments for improving sleep problems and determine which is best. The three treatments are yoga, survivorship health education, and cognitive behavioral therapy.
The Sleep Research Data Repository (SRDR) aimed to systematically collect, analyze and store for future research sleep and sleep disorders related biological and psychological information. It will include sleep physiological measurements and the results of interviews, questionnaires, and laboratory tests. The SRDR will contain sleep related information obtained from healthy subjects and patients with psychiatric, substance abuse, neurological disorders, or any medical conditions associated with sleep disturbances. SRDR data will be made available to current and future IRB-approved investigators associated with this protocol.
