Outcome Measures

Primary Outcomes (1)

  • Average Total Sleep Time (TST) as Recorded Daily in the Sleep Diary During the 14-day In-treatment Period

    TST was defined as the total amount of time (measured in minutes) that was actually spent sleeping the previous night as recorded daily in the participant's sleep diary. TST values over the 14-day active treatment period were averaged for each participant, and average TST was then reported by treatment arm. For participants with missing data, the average of the nights for which TST data were present was used in the analysis.

    Day 1 to Day 15

Secondary Outcomes (3)

  • Average Sleep Latency (SL) as Recorded Daily in the Sleep Diary During the 14-day In-treatment Period

    Day 1 to Day 15

  • Number of Participants Experiencing an Adverse Event (AE) During the 14-day In-treatment Period

    Day 1 to Day 15

  • Number of Participants Who Discontinued From Study Treatment Due to an AE During the 14-day In-Treatment Period

    Day 1 to Day 15
