Primary outcomes

  1. Change From Baseline of Wakefulness After Sleep Onset (WASO) Measured by Polysomnography (PSG)

    Time frame: Baseline, Nights 1 / 2, Nights 20 / 21

    Wakefulness After Sleep Onset, as measured by PSG, was defined as wake time after persistent sleep (wake time during sleep plus wake time after sleep, expressed in minutes). Nights 1 / 2 is the average of the PSG measurements taken during the first two nights of study drug exposure. Nights 20 / 21 is the average of the PSG measurements taken during nights 20 and 21 of study drug exposure.

Secondary outcomes

  1. Change From Baseline in Mean Sleep Efficiency (SE)

    Time frame: Baseline, Nights 1 / 2, Nights 20 / 21

    Sleep efficiency, as measured by PSG, is defined as Total Sleep Time (TST), divided by total recording time, multiplied by 100.

    Nights 1 / 2 is the average of the PSG measurements taken during the first two nights of study drug exposure. Nights 20 / 21 is the average of the PSG measurements taken during nights 20 and 21 of study drug exposure.

  2. Change From Baseline in Mean Latency to Persistent Sleep (LPS)

    Latency to onset of persistent sleep (LPS), as measured by PSG, is defined as time from lights-off to the first of 20 consecutive periods of non-wake sleep stages. Latency to persistent sleep is reported in minutes.

    Nights 1 / 2 is the average of the PSG measurements taken during the first two nights of study drug exposure. Nights 20 / 21 is the average of the PSG measurements taken during nights 20 and 21 of study drug exposure.

  3. Change From Baseline in Mean Total Sleep Time (TST)

    Time frame: Baseline, Nights 1 / 2, Nights 20 / 21

    Total sleep time, as measured by PSG, is the duration of rapid eye movement (REM) plus NREM (stages N1 + N2 + N3) during time in bed.

  5. Change From Baseline in Subjective Sleep Quality (sSleep)

    Time frame: Baseline, Nights 1 / 2, Nights 20 / 21

    Self-reported sleep outcome measured by subject diary data. Scores have a range of 1 to 5, with 1 being equal to "Very Poor" and 5 being equal to "'Very Good."

  7. Change From Baseline in Subjective Wakefulness After Sleep Onset (sWASO)

    Time frame: Baseline, Nights 1 / 2, Nights 20 / 21

  12. Proportion of Responders to V117957 1 mg and 2 mg Compared to Placebo

    Time frame: Nights 1 / 2, Nights 20 / 21

    The proportion of responders is based on subjects meeting or exceeding WASO (wakefulness after sleep onset) 15 minute threshold as derived from polysomnography (PSG).

    Nights 1 / 2 is the average of the measurements taken during the first two nights of study drug exposure. Nights 20 / 21 is the average of the measurements taken during nights 20 and 21 of study drug exposure.

  13. Occurrence of Rebound Insomnia During the Washout/Follow-up Period

    Time frame: Baseline Compared to Washout/Follow-up Period (Nights 22 / 23)

    Rebound insomnia is defined as a worsening of sleep compared with pretreatment. The comparison is based on the Wakefulness After Sleep Onset (WASO) measured by PSG of the Washout/Follow-up Period versus Baseline. If the LS means for WASO for the Washout/Follow-up Period is lower than Baseline, then no rebound insomnia was suggested. Nights 22 / 23 is the average of the measurements taken during nights 22 and 23 (Washout Period).

  14. Next Day Residual Effects as Determined by Digit Symbol Substitution Test (DSST).

    Time frame: Baseline, Night 2, Night 21

    The DSST explores attention and psychomotor speed by measuring total correct responses. The maximum score is 165. Higher scores represent better outcome/improvement.

  15. Next Day Residual Effects as Determined by Karolinska Sleepiness Scale (KSS)

    Time frame: Baseline, Night 2 (9- and 10-hours postdose), Night 21 (9- and 10-hours postdose)

    The KSS is a 9-point Likert scale (range: 1 = "extremely alert" to 9 = "very sleepy") that measures level of sleepiness.

  16. Next Day Residual Effects as Determined by Profile of Mood States (POMS) - Brief

    Time frame: Baseline, Night 2, Night 21

    The POMS-Brief contains 30 questions that assess mood states. Scores for each question range 0 = not at all to 4 = extremely. Total mood disturbance assessment is the total of the subject's subscales scores on anger/hostility, confusion/bewilderment, depression/dejection, fatigue/inertia, tension/anxiety, and vigor/activity. Total scores range from 0-120 and a higher total score indicates more mood disturbance.
