NCT01021852

Brief Summary

This was a cross-over, polysomnography (PSG) study to test the safety, tolerability and effectiveness of different doses of MK-6096 in the treatment of participants with primary insomnia. The primary efficacy hypothesis was that at least one dose of MK-6096 is superior to placebo in improving sleep efficiency (SE) as measured by PSG on Night 1 and at the end of 4 weeks of treatment (Week 4).

Outcome Measures

Primary Outcomes (3)

  • Sleep Efficiency (SE) on Night 1 and After 4 Weeks of Treatment

    SE was measured using a polysomnogram (PSG), which consisted of an electroencephalogram (EEG) for registration of brain activity during sleep, an electro-oculogram (EOG) for registration of the eye movements during sleep, and an electromyogram (EMG) for recording chin muscle activity during sleep. Sleep stage scoring was performed visually in 30-second epochs according to Rechtschaffen and Kales (R\&K) criteria and PSG data were read by a Central Reader. SE was defined as total sleep time (TST) in minutes divided by time in bed (measured from lights off to lights on; fixed at 8 hours on each PSG night) in minutes, multiplied by 100, where TST is defined as the total time (minutes) in Stages 1, 2, 3, 4 and Rapid Eye Movement (REM). SE= (total sleep time/time in bed) x 100. Least squares (LS) mean SE was reported for each treatment arm.

    Night 1 and end of Week 4

  • Percentage of Participants With at Least One Adverse Event (AE) During Treatment Periods 1 and 2

    An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the SPONSOR's product, was also an AE. The percentage of participants with AEs are presented for the first day of randomized treatment dosing (Day 1) through the last day of randomized treatment dosing (Day 29) in Treatment Periods 1 and 2.

    Day 1 through Day 29 in Treatment Periods 1 and 2 (58 days total)

  • Percentage of Participants That Discontinued Study Medication Due to an AE During Treatment Periods 1 and 2

    An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the SPONSOR's product, was also an AE. The percentage of participants that discontinued study medication due to AEs are presented for the first day of randomized treatment dosing (Day 1) through the last day of randomized treatment dosing (Day 29) in Treatment Periods 1 and 2.

    Day 1 through Day 29 in Treatment Periods 1 and 2 (58 days total)

Secondary Outcomes (2)

  • Wake After Persistent Sleep Onset (WASO) on Night 1 and After 4 Weeks of Treatment

    Night 1 and end of Week 4

  • Latency to the Onset of Persistent Sleep (LPS) on Night 1 and After 4 Weeks of Treatment

    Night 1 and end of Week 4

Study Arms (8)

MK-6096 2.5 mg/Placebo

EXPERIMENTAL

Prior to Treatment Period 1, participants undergo a 3 week screening period and receive single-blind placebo for the last 2 weeks if screening criteria are met. During Treatment Period 1, participants receive MK-6096 2.5 mg daily for 4 weeks at 5-10 minutes before bedtime and return to the sleep laboratory on Days 1 and 29 for overnight polysomnography (PSG) recordings, on which days they receive MK-6096 30 minutes before bedtime. Treatment Period 1 is followed by a 2-week washout period during which the participant receives single-blind placebo for the first 3 days and no treatment for the remaining 11 days. During Treatment Period 2, participants receive dose-matched placebo to MK-6096 daily for 4 weeks at 5-10 minutes before bedtime and return to the sleep laboratory for 2 overnight PSG recordings on Days 1 and 29 (Study Days 44 and 72), on which days they receive placebo 30 minutes before bedtime.
