SM-1 vs 2 Comparators and Placebo in Participants With a History of Transient Insomnia.
A Randomized, Double-Blind, Single-Dose, 4-Way Crossover Study to Assess the Efficacy and Safety of SM-1 (50-mg Diphenhydramine, 5-mg Delayed-Release Zolpidem, and 0.5-mg Delayed-Release Lorazepam) Versus 2 Comparators (50-mg Diphenhydramine and 5-mg Delayed-Release Zolpidem; 50-mg Diphenhydramine and 0.5-mg Delayed-Release Lorazepam) and Placebo in a 5-Hour Phase Advance Model of Transient Insomnia.

Brief Summary
The purpose of this study is to investigate the effectiveness, safety and tolerability of a combination drug product (SM-1) containing diphenhydramine, zolpidem and lorazepam, in adult participants who sometimes have difficulty in falling asleep or staying asleep, but who do not have chronic insomnia. Participants will receive SM-1, or a combination of diphenhydramine and zolpidem, or a combination of diphenhydramine and lorazepam, or placebo during 4 one-night stays at a sleep center.

Eligibility Criteria
You may qualify if:
- Signed written consent form.
- Experienced at least 1 prior episode of transient insomnia meeting all of the following criteria: difficulty falling asleep or staying asleep; next day impairment or distress associated with the disturbed sleep; frequency of 1 to 7 nights per week; duration of less than 1 month or more than 1 month of intermittent episodes.
- Routinely spends 6.5 - 9.5 hours in bed each night, with bed time varying no more than 2 hours over a week. Potential participants will be required to complete a paper diary for a minimum of 7 days during the screening period, with at least 5 entries completed over the 7 days.
- Body Mass Index (BMI) between 19 and 32 kg/m2.
- Good general health, as determined by a thorough medical, sleep and psychiatric history review, brief physical examination including vital sign measurements, and an assessment of screening laboratory test results.
- Female subjects of childbearing potential must be using an acceptable method of contraception during the study and for the 30 days following the last dose of study drug, and must have a negative urine pregnancy test at every study visit. Female subjects of non-childbearing potential are not required to use contraception if they have been surgically sterilized or are post-menopausal as defined by the cessation of menses for a period of at least 2 years before screening.
- Male subjects must use an acceptable method of contraception during the study and for the 30 days following the last dose of study drug.
- Willing and able to be confined to the study center for 1 night in each of 4 treatment periods, as required by the protocol.
- Refrains from the use of alcohol within 24 hours of check-in for each of 4 treatment periods involving an overnight stay at the study center.
- Refrains from napping (any sleep episode occurring outside subject's main sleep episode) on days of check-in for each of 4 treatment periods involving an overnight stay at the study center.
You may not qualify if:
- Females who are pregnant, breast-feeding, or planning a pregnancy during the study period.
- Clinically significant medical disorder or currently unstable medical condition that, in the opinion of the investigator, would confound the results of the study.
- Abnormal laboratory value at screening, judged clinically significant by the investigator.
- History or current evidence of severe hepatic (liver) impairment.
- Clinically significant psychiatric illness, or the history or presence of a major psychiatric illness in the past year.
- Clinically significant abnormal finding on physical examination, as determined by the investigator.
- Lifetime history of seizure disorder (other than childhood febrile seizures) or serious head injury.
- History of chronic insomnia or other sleep disorders, such as sleep apnea, narcolepsy, parasomnia, restless leg syndrome, or circadian rhythm disorder.
- Air travel across more than 2 time zones, an expected change in sleep schedule, or involvement in night work or shift work within 1 month before screening or during the study period.
- Reports a recent history of napping of more than once per week.
- History of alcohol or substance use disorder within the year before screening, or current evidence of alcohol or substance use disorder.
- Self-report of a usual consumption of more than 14 units of alcohol per week. One unit of alcohol is equivalent to 12 ounces of beer, 4 ounces of wine, or 1 ounce of liquor.
- Regular consumption of more than 500 mg of caffeine per day.
- History of routinely smoking during sleep period.
