Overview
Brief Summary
This study will be conducted to evaluate the effects on cognitive performance (Power of Attention domain) and postural stability of lemborexant in combination with alcohol versus lemborexant alone and versus alcohol alone in healthy participants. This study will also assess the safety and tolerability of a single oral dose of lemborexant when administered alone or in combination with alcohol in healthy participants.

Eligibility Criteria
Inclusion Criteria
- •Participants must meet all of the following criteria to be included in this study:
- •Healthy male or female, 19 to 55 years of age, inclusive, at the time of informed consent.

- •Current alcohol users who are occasional or regular drinkers, operationally defined as consuming at least 2 alcoholic beverages per week but not more than 2 alcoholic beverages per day in an average week, in the 6 months before Screening. This would result in consumption of 2 to 14 standard drinks per week, on average; 1 standard drink is equivalent to 43 mL (1.5 ounce \[oz.\]) of spirits (≥20% alcohol by volume), 142 mL (5 oz.) of wine, or 341 mL (12 oz.) of beer.
- •Able to speak, read, and understand English sufficiently to allow completion of all study assessments.
- •Provide written informed consent.
Exclusion Criteria
- •Participants who meet any of the following criteria will be excluded from this study:
- •Females who are breastfeeding or pregnant.
- •Females of childbearing potential. 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 (i.e., bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month before dosing).

- •≥7 on Narcolepsy subscale.
- •Current or prior diagnosis of any condition for which alcohol consumption is contraindicated (e.g., hypertriglyceridemia, pancreatitis, liver disease, porphyria, or congestive heart failure, judged as clinically relevant by the investigator).
- •Evidence of disease that may influence the outcome of the study within 4 weeks prior to the first dose of study drug (e.g., congenital abnormality in metabolism, psychiatric disorders, and disorders of the gastrointestinal tract, liver, kidney, respiratory system, endocrine system, hematological system, neurological system, or cardiovascular system).
- •Has been diagnosed with cancer within the 5 years before Screening (excluding squamous or basal cell carcinoma of the skin), or has an active malignancy of any type (including squamous or basal cell carcinoma of the skin).

Outcomes
Primary Outcomes
Change from baseline in body sway, as assessed by an ataxia meter measuring directional trunk movements, for lemborexant plus alcohol compared to lemborexant alone
Time Frame: Baseline; Up to approximately 12 weeks postdose in each single-dose treatment period
Body sway will be detected through a cable around the participant's waist by the ataxia meter. Body sway will be measured in units of 1/3° of the angle of arc. For ease in reporting, these will be called arbitrary units, with a higher number indicating more body sway (less postural stability).

Change from baseline in Power of Attention, per the PAB, for lemborexant plus alcohol compared to alcohol alone
Time Frame: Baseline; Up to approximately 12 weeks postdose in each single-dose treatment period
The PAB comprises 9 tasks: Simple Reaction Time; Choice Reaction Time; Digit Vigilance; Immediate Word Recall; Delayed Word Recall; Numerical Working Memory; Spatial Working Memory; Word Recognition; Picture Recognition. Four composite domain factor scores will be calculated by combining outcome variables from the various tests. The 4 domains are Power of Attention, Continuity of Attention, Quality of Memory, and Speed of Memory Retrieval. The Power of Attention score is a composite score from the speed scores of 3 tests of attention (Simple Reaction Time, Choice Reaction Time, Digit Vigilance) and reflects the ability to focus attention and process information. A higher score indicates better performance.
