Active clinical trials for "Disorders of Excessive Somnolence"

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.

The purpose of this study is to determine whether methylphenidate is effective in the treatment of excessive daytime sleepiness due to myotonic dystrophy type 1 (DM1).

This is a multicentric International Phase III,Long term open label study(12 months)assessing the long-term safety and efficacy of BF2.649 (Pitolisant)in the treatment of Excessive Daytime Sleepiness (EDS) in narcoleptic patients with or without cataplexy.

Prospective, multicenter, double-blind, phase II, randomized, dose-response study in 5 parallel groups (dose-range).

The purpose of this study is to test the effect of modafinil on the negative symptoms, such as blunted affect and social withdrawal, of schizophrenic patients and to determine modafinil's effect on excessive daytime sleepiness. A secondary purpose of the study is to examine the effect of modafinil on cognitive functioning of schizophrenic patients.

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).

A 12 Month, Open-Label, Flexible Dosage Extension Study of the Safety and Efficacy of Armodafinil (CEP-10953) in the Treatment of Patients with Excessive Sleepiness Associated with Narcolepsy, Obstructive Sleep Apnea/Hypopnea Syndrome, or Chronic Shift Work Sleep Disorder

3. RATIONALE FOR BF2.649 IN NARCOLEPSY Narcolepsy is a disabling syndrome affecting the generation and organizations of sleep and wakefulness, first described by Westphal and Gelineau in 19th century. Excessive Daytime Sleepiness (EDS) and cataplexy are two main symptoms of narcolepsy. Other symptoms referred to as auxiliary symptoms are hypnagogic and hypnopompic hallucinations, sleep paralysis, dyssomnia and automatic behaviour. The prevalence of narcolepsy is estimated around 25 per 100 000 in Causasian population. It is often extremely incapacitating, interfering with every aspect of life, in work and social settings. Several breakthroughs in the understanding of physiopathology of narcolepsy have recently shown that most narcoleptic patients display a strongly decreased CSF level of orexins, a group of hypothalamic peptides with wake-promoting activity. It was also found that sporadic narcolepsy in dogs, mice and humans may also be related to a deficiency in the production of orexin ligands. Narcolepsy may be a neurodegenerative or autoimmune disorder resulting in a loss of hypothalamic neurons containing the orexin [Baumann CR & Bassetti CL Lancet Neurol. 2005 ; Dauvilliers Y et al, Clin Neurophysiol. 2003 ]. In accordance with guidelines published by the European task force [Billiard M et al, Eur J Neurol. 2006] , management of narcolepsy with or without cataplexy relies on several classes of drugs, namely stimulants for EDS, antidepressants for cataplexy and hypnosedative drugs for disturbed nocturnal sleep. The first line pharmacological treatment of EDS and irresistible episodes of sleep rely on Modafinil, 100-400 mg/day, given in two doses, one in the morning and one early in the afternoon, the need for amphetamines and amphetamine-like stimulants (e.g. methylphenidate) has been decreased. Sodium oxybate and antidepressants are main drug therapies of cataplexy. BF2.649, an H3R inverse agonist promotes significantly vigilance in mice knock out for the orexin gene, a reliable model of narcolepsy, whereas the animals remain calm, a difference with treatment by amphetamine-like drugs which induce psychomotor excitation. In addition, BF2.649 shows a significant inhibitory effect on the occurrence of narcolepsy episodes during the dark period. These narcolepsy episodes are to be compared to cataplexy episodes in human [Chemelli et al., Cell 1999] 11. In agreement, Modafinil, in humans, does not show any effects on cataplexy, even if it improves wakefulness by an ill-defined mechanism. Thus anticataplectic drugs, such as antidepressants, are given in addition to Modafinil to narcoleptic patients. Taken together, the preclinical and clinical results provide a compelling rationale for this study to verify and confirm, under randomized double-blind and placebo-controlled conditions, the safety and efficacy of escalating dose of BF2.649 in the treatment of EDS and cataplexy in narcolepsy. It is on the basis of preclinical studies, and on the observation of the first included patients, that the doses to be administered were determined.

Obstructive sleep-disordered breathing (SDB) affects 2-3% of children and may lead to problems with nighttime sleep and daytime behavior, learning, sleepiness, and mood. Adenotonsillectomy (AT) is the second most common surgical procedure in children. It is now performed more often for suspected SDB than for any other indication. However, recent studies indicate that many if not most children still have SDB after AT, and many still have learning or behavioral problems associated with SDB. The goals of this study are: (1) to assess the extent that behavior, cognition, and sleepiness in children can improve with Continuous positive airway pressure (CPAP) treatment after AT, and (2) to identify which patients stand to gain most from post-operative assessment and treatment.

Double blind, randomized, parallel groups study of Pitolisant versus placebo, in narcoleptic patients experiencing EDS, and cataplexy (minimum of 3 complete or partial cataplexy attacks per week). The patients will be treated during 7 weeks with Pitolisant or placebo.
