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.
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.
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.
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.

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 in a subpopulation of patients with greater than 60 minutes to fall asleep after a MOTN awakening at baseline.
