modafinil and Sleep Disorders, Circadian Rhythm

modafinil has been researched along with Sleep Disorders, Circadian Rhythm in 36 studies

Modafinil: A benzhydryl acetamide compound, central nervous system stimulant, and CYP3A4 inducing agent that is used in the treatment of NARCOLEPSY and SLEEP WAKE DISORDERS.
modafinil : A racemate comprising equimolar amounts of armodafinil and (S)-modafinil. A central nervous system stimulant, it is used for the treatment of sleeping disorders such as narcolepsy, obstructive sleep apnoea, and shift-work sleep disorder. The optical enantiomers of modafinil have similar pharmacological actions in animals.
2-[(diphenylmethyl)sulfinyl]acetamide : A sulfoxide that is dimethylsulfoxide in which two hydrogens attached to one of the methyl groups are replaced by phenyl groups, while one hydrogen attached to the other methyl group is replaced by a carbamoyl (aminocarbonyl) group.

Sleep Disorders, Circadian Rhythm: Dyssomnias associated with disruption of the normal 24 hour sleep wake cycle secondary to travel (e.g., JET LAG SYNDROME), shift work, or other causes.

Trial Overview

Trial Outcomes

Clinical Global Impression of Change (CGI-C)

Number of participants who had at least minimal improvement in CGI-C ratings at Week 12 or last post-baseline visit. The CGI-C uses the following categories and scoring assignments: 1=Very much improved; 2=Much improved; 3=Minimally improved; 4=No change; 5=Minimally worse; 6=Much worse; and 7=Very much worse. Severity of illness was assessed at baseline by the CGI-S, which consists of the following categories: 1=Normal (shows no signs of illness); 2=Borderline ill; 3=Mildly (Slightly) ill; 4=Moderately ill; 5=Markedly ill; 6=Severely ill; and 7=Among the most extremely ill patients. (NCT00080288)
Timeframe: up to 12 weeks

Multiple Sleep Latency Test (MSLT)

The Multiple Sleep Latency Test (MSLT) is an objective assessment of sleepiness that measures the ability of a subject to remain awake. Long latencies to sleep are indicative of a patient's ability to remain awake. Mean sleep latency from MSLT was measured for five 20-minute (maximum) MSLT naps performed at scheduled visits (2400 [midnight], 0200, 0400, 0600, and 0800).The MSLT was administered at weeks 4, 8, and 12. The primary efficacy variable was the mean change from the baseline assessment in MSLT sleep latency as assessed at week 12 (or last postbaseline visit). (NCT00080288)
Timeframe: up to 12 weeks

Change From Baseline to Endpoint in Global Assessment of Function (GAF) Score

The Global Assessment of Functioning (GAF) is a numeric scale (0 through 100) used by the clinician to rate the social, occupational, and psychological functioning of the patient. A higher score indicates superior functioning and fewer symptoms. The data presented here represents the mean change from baseline to endpoint in the GAF scores of each group. (NCT01080807)
Timeframe: Baseline and week 6 (or last observation after baseline)

Change From Baseline to Endpoint in the Functional Outcomes of Sleep Questionnaire (FOSQ-10) Activity Level Score

FOSQ-10 consists of 10 questions rated on a scale of 1 to 4 (1=extreme difficulty and 4=no difficulty), and is used to measure the impact of daytime sleepiness on activities of daily living and quality of life. A total score and 5 subscale (vigilance, general productivity, social outcome, intimacy, and activity level) scores are calculated from the responses. Worst subscale score is 1 (maximum difficulty) and the best score is 4 (no difficulty). This score represents the CHANGE from Baseline in the Activity level subscale. Positive change scores represent improvement (possible range -3 to +3). (NCT01080807)
Timeframe: Baseline and week 6 (or last observation after baseline)

Change From Baseline to Endpoint in the Functional Outcomes of Sleep Questionnaire (FOSQ-10) Total Score

FOSQ-10 consists of 10 questions, on a scale of 1-4(1=extreme difficulty 4=no difficulty), measures impact of sleepiness on activities of daily living. Lower score = more difficulty with activity due to lack of sleep. Total score = MEAN of subscale scores (vigilance, productivity, social outcome, intimacy, activity) multiplied by 5. Worst total score is 5 (maximum difficulty) the best is 20 (no difficulty). This data reports CHANGE in total score from baseline to endpoint, with higher (positive) values representing improvement. Worst possible CHANGE value would be -15 best would be +15. (NCT01080807)
