Primary Outcome Measures
NameTimeMethod
Latency to Persistent Sleep After Middle-of-the-Night Awakening as Measured by PolysomnographyDays 1 and 2 for each treatment

Polysomnography was used to measure the time to return to persistent sleep after a middle-of-the-night (MOTN) awakening for each day of every two-day treatment period.

Secondary Outcome Measures
NameTimeMethod
Number of Treatment Responders Based on Polysomnography Latency to Persistent Sleep After Middle-of-the-Night AwakeningDays 1 and 2 for each treatment

Polysomnography was used to measure the time to return to persistent sleep after a middle-of-the-night (MOTN) awakening for each day of every two-day treatment period. A participant was considered to be a responder if the time to return to persistent sleep was less than twenty minutes.

Total Sleep Time After Scheduled Middle-of-the-Night Awakening Measured by PolysomnographyDays 1 and 2 for each treatment

Polysomnography was used to measure the time from return to persistent sleep after a middle-of-the-night (MOTN) awakening until final awakening for each day of every two-day treatment period.

Average Subjective Total Sleep Time After Scheduled Middle-of-the-Night AwakeningDays 1 and 2 for each treatment

The time from return to persistent sleep after a middle-of-the-night (MOTN) awakening until final awakening for each day of every two-day treatment period was recorded by each participant using the Treatment Morning Sleep Questionnaire.

Subjective Sleep Quality RatingDays 1 and 2 for each treatment

Sleep quality was rated by participants for each day of every two-day treatment period using the Treatment Morning Sleep Questionnaire. The percentage of participants within each rating category is reported. The rating scale was poor, fair, good and excellent.

Subjective Level of Refreshed SleepDays 1 and 2 for each treatment

Level of refreshed sleep was rated by participants for each day of every two-day treatment period using the Treatment Morning Sleep Questionnaire. The percentage of participants within each rating category is reported. The rating scale was poor, fair, good and excellent.

Subjective Ability to FunctionDays 1 and 2 for each treatment

Ability to function was rated by participants for each day of every two-day treatment period using the Treatment Morning Sleep Questionnaire. The percentage of participants within each rating category is reported. The rating scale was poor, fair, good and excellent.

Polysomnography Sleep Efficiency After Scheduled Middle-of-the-Night AwakeningDays 1 and 2 for each treatment

Sleep efficiency is a measurement of the percentage of time asleep to the total time in bed. It was measured by polysomnography for each day of every two-day treatment period.

Subjective Sleep Onset Latency After Middle-of-the-Night AwakeningDays 1 and 2 for each treatment

Participants documented the time to return to sleep after a middle-of-the-night (MOTN) awakening for each day of every two-day treatment period using the Treatment Morning Sleep Questionnaire.

Polysomnography Wake Time After Sleep Onset Following Middle-of-the-Night AwakeningDays 1 and 2 for each treatment

Amount of time awake after sleep onset following a middle-of-the-night awakening was measured by polysomnography for each day of every two-day treatment period.

Subjective Wake Time After Sleep Onset After Middle-of-the-Night AwakeningDays 1 and 2 for each treatment

Amount of time awake after sleep onset following a middle-of-the-night awakening was recorded by participants using the Treatment Morning Sleep Questionnaire for each day of every two-day treatment period.

Polysomnography Number of Awakenings After Middle-of-the-Night AwakeningDays 1 and 2 for each treatment

Number of times a participant awoke following sleep onset after the middle-of-the-night awakening, as measured by polysomnography for each day of every two-day treatment period.
