Sleep Initiation and Maintenance Disorders
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Primary Purpose: Treatment
||A 28 Day, Polysomnographic and Subjective Assessment of GW679769 for the Treatment of Primary Insomnia: A Randomized, Double-blind, Parallel-Group, Placebo-Controlled Trial.
Primary Outcome Measures:
- Comparison of GW679769 and placebo on the time needed to fall asleep at bedtime on Nights 1/2, 13/14 and 27/28 of treatment, as assessed by electroencephalography and other physiological changes during sleep. [ Time Frame: 28 Days ]
Secondary Outcome Measures:
- Comparison of GW679769 and placebo effects on sleep maintenance and duration on Nights 1/2, 13/14 and 27/28 of treatment, as assessed by electroencephalography and subject diaries, and on next-day memory, alertness and physical coordination. [ Time Frame: 28 Days ]
