Primary Outcome Measures :
  1. Maximum Observed Plasma Concentration (Cmax) of Lemborexant [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
  2. Area Under the Plasma Concentration-Time Curve From Time Zero to 72 Hours Post Dose (AUC[0-72h]) of Lemborexant [ Time Frame: Day 1: predose, 0.5 up to 72 hours postdose ]
  3. Area Under the Plasma Concentration-Time Curve From Time Zero to the Time of the Last Quantifiable Concentration (AUC[0-t]) of Lemborexant [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
  4. Area Under the Plasma Concentration-Time Curve Extrapolated to Infinity (AUC[0-inf]) of Lemborexant [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]

Secondary Outcome Measures :
  1. Maximum Observed Plasma Concentration (Cmax) of Metabolites of Lemborexant (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
  2. Time to Reach Maximum Plasma Concentration (Tmax) of Lemborexant and Its Metabolites (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
  3. Area Under the Plasma Concentration-Time Curve From Time Zero to 8 Hours Post Dose (AUC[0-8h]) of Lemborexant and Its Metabolites (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 8 hours postdose ]
  4. Area Under the Plasma Concentration-Time Curve From Time Zero to 72 Hours Post Dose (AUC[0-72h]) of Metabolites of Lemborexant (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 72 hours postdose ]
  5. Area Under the Plasma Concentration-Time Curve From Time Zero to the Time of the Last Quantifiable Concentration (AUC[0-t]) of Metabolites of Lemborexant (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
  6. Area Under the Plasma Concentration-Time Curve Extrapolated to Infinity (AUC[0-inf]) of Metabolites of Lemborexant (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
  7. Area Under the Plasma Concentration-Time Curve Adjusted by Unbound Fraction of Plasma (AUCu) of Lemborexant and Its Metabolites (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
    AUCu was defined as the AUC(0-inf) adjusted by unbound fraction in plasma, and calculated by multiplying the value of AUC(0-inf) with Plasma protein unbound fraction (fu).

  8. Percentage of AUC(0-inf) Based on Extrapolation (AUCex) of Lemborexant and Its Metabolites (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
    AUCex was calculated by dividing the difference of (AUC(0-inf) and AUC(0-t)) by value of AUC(0-inf) and then multiplying the value by 100.

  9. Observed Terminal Elimination Half-life (t1/2) of Lemborexant and Its Metabolites (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
    Terminal plasma half-life is the time required for plasma/blood concentration to decrease by 50%. This is not the time required to eliminate half the administered dose.

  10. Observed Elimination Rate Constant (LambdaZ) of Lemborexant and Its Metabolites (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
    Estimated by linear regression through at least three data points (not including tmax) in the terminal phase of the log concentration-time profile.

  11. Apparent Body Clearance (CL/F) of Lemborexant [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
    CL/F is the clearance for parent Lemborexant only and was calculated as Dose/[AUC0-inf]. Blood samples were analyzed for the amount of Lemborexant in the plasma.

  12. Apparent Volume of Distribution (Vz/F) Based on the Terminal Phase of Lemborexant [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
    The apparent volume of distribution gives information about the amount of Lemborexant distributed in body tissue rather than the blood/plasma. Vz/F for parent Lemborexant only was calculated as Dose /([ λz]*[AUC0-inf]).

  13. Metabolite-to-Parent Ratio of AUC(0-inf), Corrected for Molecular Weights (MPR AUC[0-inf]) of Metabolites of Lemborexant (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
    The AUC metabolite to parent ratio (MPR) is the ratio of AUC(0-inf) of the individual metabolite to AUC(0-inf) of lemborexant, corrected for molecular weights.

  14. Plasma Protein Unbound Fraction (Fu) of Lemborexant and Its Metabolites (M4, M9, and M10) [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
    Unbound fraction of drug in plasma was calculated as 100% minus (-) mean percent of Lemborexant and Its Metabolites M4. M9. M10 bound to plasma protein for each participant.

  15. Apparent Clearance Relative to the Unbound Plasma Concentration (CLu/F) Based on AUCu of Lemborexant [ Time Frame: Day 1: predose, 0.5 up to 240 hours postdose ]
    Unbound fraction of drug in plasma was calculated as 100% - mean percent of Lemborexant bound to plasma protein for each participant.

  16. Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) [ Time Frame: Up to Day 11 ]
  17. Number of Participants With Clinically Significant Laboratory Abnormalities [ Time Frame: Up to Day 11 ]
  18. Number of Participants With Clinically Significant Abnormal Vital Sign Values [ Time Frame: Up to Day 11 ]
  19. Number of Participants With Clinically Significant Abnormal Electrocardiogram (ECG) Parameter Values [ Time Frame: Up to Day 11 ]

Inclusion Criteria:

Inclusion Criteria for All Participants:

  • Male or female participants, ages 18 to 79 years, inclusive, at the time of informed consent.
  • Body Mass Index between 18 and 40 kilograms per meters squared (kg/m^2), inclusive, at Screening.
  • Voluntary agreement to provide written informed consent, and the willingness and ability to comply with all aspects of the protocol.
  • Nonsmokers or smokers who smoke 20 cigarettes or less per day.
  • Participants with normal liver function.

Additional Inclusion Criteria for Healthy Participants:

  • Estimated glomerular filtration rate (eGFR) is ≥ 90 mL/min/1.73 m^2, as determined by the Modification of Diet in Renal Disease (MDRD) formula.

Additional Inclusion Criteria for Participants with Renal Impairment:

- Diagnosis of severe renal impairment (eGFR is 15 to 29 mL/min/1.73 m^2, as determined by the MDRD formula) that has been stable (without any change in disease status) for 60 days prior to study Screening and is confirmed on Day -1, as determined by the investigator by MDRD formula. If the renal function classification for the participant changed from screening to Day -1, eGFR should be repeated once within 24 to 48 hours. If eGFR variability across these scheduled and repeat time points indicates the participant does not consistently meet the criteria for one renal category group, participant enrollment into a renal category group will be at the discretion of the medical monitor and investigator, in consultation with the Sponsor.

Exclusion Criteria:

Exclusion Criteria for All Participants:

  • Females who are breastfeeding or pregnant at Screening or Baseline.
  • Females of childbearing potential who did not use a highly effective method of contraception within 28 days before study entry, or who did not agree to use an approved method of contraception from 28 days before study entry, throughout the entire study period, and for 28 days after study drug discontinuation.

Additional Exclusion Criteria for Participants With Renal Impairment:

  • Any history of renal transplant.
  • Any known significant bleeding diathesis (e.g., history of recent bleeding from esophageal varices), which could preclude multiple venipuncture or deep intramuscular injections.
  • New significant illness that onset within 2 weeks prior to study drug administration.
  • Current clinically relevant disease other than the renal impairment (e.g., cardiac, hepatic, gastrointestinal disorder, or a condition which may impact drug absorption), as determined by the investigator. Participants with a history of Type I or Type II diabetes may be eligible, providing that, in the investigator's opinion, the disease has been stable.
