Outcome Measures

Primary Outcomes (3)

  • Change From Baseline in Total Sleep Time (TST)

    TST was defined as the time recorded for sleep diary question 6 "how much time did you actually spend sleeping" as reported by the participants using a LogPad (hand-held electronic data capture device). Baseline was defined as the TST from the last week of the base study. Daily diary data were converted to weekly averages. For each treatment week the non-missing diary data of that week were taken into account; if a treatment week had three non-missing morning diaries or less, the data of the previous week were taken into account, weighing the data of both weeks, using the number of observed diaries as weights (weighted mean); if no diary data were available for a treatment week the data were considered as missing and were not imputed.

    Baseline and Week 26

  • Number of Participants Experiencing Adverse Events (AEs)

    An adverse event is any unfavorable and unintended change in the structure, function, or chemistry of the body whether or not considered related to the study treatment.

    Up to 30 weeks

  • Number of Participants Discontinuing Due to AEs

    An adverse event is any unfavorable and unintended change in the structure, function, or chemistry of the body whether or not considered related to the study treatment.

    Up to 26 weeks
