Study Arms:
- MK-6096 2.5 mg/Placebo (Type: 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.
- Placebo/MK-6096 2.5 mg (Type: 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 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, on which days they receive placebo 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.
