Purpose

A 2-night polysomnography / 5-way cross-over study to evaluate the effect, safety and tolerability of oral administration of almorexant (ACT 078573) in elderly subjects with primary insomnia.

Primary Outcome Measures:

Mean Wake Time After Sleep Onset (WASO) [ Time Frame: 2 treatment nights ] [ Designated as safety issue: No ]
WASO was the time in minutes scored as wake between the onset of persistent sleep and lights on, where the onset of persistent sleep was the beginning of the first continuous 20 epochs (10 min) scored as non-wake.

Mean values were calculated based on 2 treatment PSG nights. PSG nights identified as non-evaluable due to protocol violation were excluded. If a mean value could not be calculated because the value for 1 PSG night was missing or non-evaluable, the valid value for the other PSG night was used. If during a double-blind treatment period a valid PSG was performed but the WASO was missing (e.g., persistent sleep did not occur), the missing value was substituted with the highest value recorded for the subject during the study (single-blind period included).

Secondary Outcome Measures:

Mean Total Sleep Time (TST) [ Time Frame: 2 treatment nights ] [ Designated as safety issue: No ]
TST was the amount of actual sleep time measured in minutes scored as non-wake (i.e., sleep stage 1, 2, slow-wave sleep, or rapid eye movement (sleep)).

Mean values were calculated based on 2 treatment PSG nights. PSG nights identified as non-evaluable by protocol violation were excluded. If a mean value could not be calculated because the value for 1 PSG night was missing or non-evaluable, the valid value for the other PSG night was used. If during a double-blind treatment period a valid PSG was performed but the TST was missing (e.g., the subject did not sleep or persistent sleep did not occur), the missing value was substituted with the worst value recorded for the subject during the study (single-blind period included).
