• Complains of dissatisfaction with nighttime sleep despite adequate opportunity for sleep, with complaint being one or more of the following: difficulty getting to sleep, difficulty staying asleep, or awakening earlier in the morning than desired.
• Frequency of complaint greater than or equal to 3 times per week.
• Duration of complaint greater than or equal to 3 months.
• Associated with complaint of daytime impairment.
• Insomnia Severity Index score greater than or equal to 15 at Screening.
• Regular time in bed between 7 and 9 hours as reported at Screening.
• Regular bedtime, defined as the time the participant attempts to fall asleep, between 21:00 and 24:00 and regular wake time between 05:00 and 09:00 as reported at Screening.
• Confirmation of current insomnia symptoms as determined from responses on the Sleep Diary completed for 7 nights during Screening, such that participant Sleep Onset Latency (sSOL) greater than or equal to 30 minutes on at least 3 nights and subjective Wake After Sleep Onset (sWASO) greater than or equal to 60 minutes on at least 3 nights.

You may not qualify if…

• Excessive morning sleepiness at Baseline as determined by average SOL at Baseline less than 10 minutes.
• Females must not be lactating or pregnant at Screening or Baseline (documented by a negative beta-human chorionic gonadotropin [beta-hCG] or human chorionic gonadotropin [hCG] test with a minimum sensitivity of 25 IU/L or equivalent units of beta-hCG or hCG). (Note: A negative urine pregnancy test is required at check-in before each dose of study drug and flurazepam).
• If females of childbearing potential:
• Had unprotected sexual intercourse within 30 days before study entry and do not agree to use a highly effective method of contraception (eg, total abstinence, an intrauterine device, a double-barrier method [such as condom plus diaphragm with spermicide], a contraceptive implant, an oral contraceptive, or have a vasectomized partner with confirmed azoospermia) throughout the entire study period or for 28 days after study drug discontinuation.
• Are currently abstinent, and do not agree to use a double barrier method (as described above) or refrain from sexual activity during the study period or for 28 days after study drug discontinuation.
• Are using hormonal contraceptives but are not on a stable dose of the same hormonal contraceptive product for at least 4 weeks before dosing and do not agree to use the same contraceptive during the study or for 28 days after study drug discontinuation.
• NOTE: All females will be considered to be of childbearing potential unless they are postmenopausal (amenorrheic for at least 12 consecutive months, in the appropriate age group, and without other known or suspected cause) or have been sterilized surgically (ie, bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month before dosing).
• A current diagnosis of sleep-related breathing disorder, periodic limb movement disorder, restless legs syndrome, circadian rhythm sleep disorder, or narcolepsy, or an exclusionary score on screening instruments to rule out individuals with symptoms of certain sleep disorders other than insomnia.
• Reports experiencing within the past year confusional arousals, symptoms of REM Behavior Disorder, or sleep-related violent behavior on Munich Parasomnia Scale (MUPS), or a history of aberrant nocturnal behaviors including sleep-driving or sleep-eating.
• Habitually naps more than 3 times per week.
• History of drug or alcohol dependency or abuse within approximately the last 2 years.
• Has a positive drug screen at Screening.
• A prolonged QT/QTc interval (QTc greater than 450 ms) as demonstrated by a repeated ECG at Screening (repeated only if initial ECG indicates a QTc interval greater than 450 ms).
• Any suicidal ideation with intent with or without a plan at Screening or within 6 months of Screening or any lifetime suicidal behavior.
• Evidence of clinically significant disease (eg, cardiac, respiratory, gastrointestinal, renal, psychiatric or neurological disease, or chronic pain) that in the opinion of the investigator(s) could affect the participant's safety or interfere with the study assessments.
• Used any prohibited prescription or over-the-counter concomitant medications within 2 weeks prior to Screening, or between Screening and Randomization.
• Used any modality of treatment for insomnia, including cognitive behavioral therapy or marijuana within 2 weeks prior to Screening, or between Screening and Randomization.
• Scheduled for surgery during the study.
• Transmeridian travel across more than 3 time zones in the 2 weeks before Screening, or between Screening and Baseline, or plans to travel more than 3 times zones during the study.
• Hypersensitivity to flurazepam, the study drug, or any of the excipients.
• Currently enrolled in another clinical trial or used any investigational drug or device within 28 days or 5 x the half-life, whichever is longer preceding informed consent.
