Primary Outcome Measures:
  • Latency to Persistent Sleep After Middle-of-the-Night Awakening as Measured by Polysomnography [ Time Frame: Days 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:
  • Number of Treatment Responders Based on Polysomnography Latency to Persistent Sleep After Middle-of-the-Night Awakening [ Time Frame: Days 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 Polysomnography [ Time Frame: Days 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 Awakening [ Time Frame: Days 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 Rating [ Time Frame: Days 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 Sleep [ Time Frame: Days 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 Function [ Time Frame: Days 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 Awakening [ Time Frame: Days 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 Awakening [ Time Frame: Days 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 Awakening [ Time Frame: Days 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 Awakening [ Time Frame: Days 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 Awakening [ Time Frame: Days 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.
