Sleep Initiation and Maintenance Disorders
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Crossover Assignment
Primary Purpose: Treatment
||A Randomized, Double-blind, Placebo-controlled, Cross-over Study to Evaluate the Effects of GW679769 on Polysomnographic Sleep Recordings, Subjective Sleep Assessment, and Daytime Cognitive Function in Elderly and Non-elderly Subjects With Primary Insomnia
Primary Outcome Measures:
- Comparison of GW679769 and placebo on the average time needed to fall asleep after bedtime dosing on two consecutive nights, as assessed by electroencephalography and other physiological changes during sleep. [ Time Frame: 48 Hours ]
Secondary Outcome Measures:
- Comparison of GW679769 and placebo on sleep maintenance and duration after bedtime dosing on two consecutive nights, as assessed by electroencephalography and subject diaries, and on next-day memory, alertness and physical coordination. [ Time Frame: 48 Hours ]
