Primary Outcome Measures :
  1. Number of participants with any serious adverse event and number of participants with any non-serious adverse event [ Time Frame: up to Day 35 (Termination/Visit 5) ]
    An adverse event is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. A serious adverse event is defined as any adverse event occurring at any dose that results in any of the following outcomes: results in death; is life threatening; results in inpatient hospitalization or prolongation of existing hospitalization; results in a persistent or significant incapacity or substantial disruption of the ability to conduct normal life function; results in a congenital anomaly/birth defect; or can be defined as any other important medical event.

  2. Number of participants with an abnormal, clinically significant laboratory test value [ Time Frame: Screening; Baseline; Days 4, 8, 11, 14, 20 (Out-Patient Follow-up), and 35 (Termination/Visit 5); up to Day 62 (unscheduled Follow-up visits) ]
    Laboratory test values will be assigned a low/normal/high (LNH) classification according to whether the value was below (L), within (N), or above (H) the laboratory parameter's reference range. Clinical significance will be determined by the Investigator.

  3. Number of participants with an abnormal, clinically significant vital sign value [ Time Frame: Screening; Baseline; up to Day 62 ]
    Vital sign measurements (ie, systolic and diastolic blood pressure [BP] [millimeters of mercury (mmHg)], heart rate [beats per minute], respiratory rate [breaths per minute], body temperature [centigrade]) will be obtained in the supine position by a validated method. Clinical significance will be determined by the Investigator.

  4. Number of participants with an abnormal, clinically significant electrocardiogram (ECG) finding [ Time Frame: Screening; Baseline; up to Day 62 ]
    Twelve-lead standard ECGs will be recorded in triplicate. ECGs will be recorded after the participant has been in the supine position for at least 10 minutes before and during the reading. In addition, all ECGs will be obtained before blood draws. Clinical significance will be determined by the Investigator.

  5. Clinical assessment of suicidality per the suicidality rating scale [ Time Frame: Baseline (Day -1), 24 hours after dosing (Day 2), Day 15, Day 20, Day 35 (Termination/Visit 5), up to Day 62 (unscheduled Follow-up visits) ]
    The suicidality rating scale will rate a participant's degree of suicidal ideation on a scale, ranging from "wish to be dead" to "active suicidal ideation with specific plan and intent." The decision to classify an isolated suicidality rating scale response as an adverse event will be exercised through medical and scientific judgment.

  6. Mean quality of sleep score per the Waketime Questionnaire, if necessary [ Time Frame: up to Day 62 ]
    Participants reporting adverse events (AEs) relating to abnormal dreams, nightmares, or sleep terrors will be questioned using the Waketime Questionnaire which is comprised of 5 individual questions. A participant is asked to rate the quality of their sleep as: 1, Very sound or restful; 2, Sound or restful; 3, Average quality; 4, Restless; or 5, Very restless.


Secondary Outcome Measures :
  1. Mean maximum observed concentration (Cmax) of E2609 and metabolites on Day 1 and Day 14 [ Time Frame: Days 1 and 14: predose; 1, 2, 3, 4, 6, and 10 hours postdose ]
    Cmax is defined as the maximum observed concentration that a drug achieves in a specified compartment or test area of the body after the drug has been administered. Using non-compartmental analysis, plasma concentrations of E2609 and metabolites will be analyzed to determine Cmax. Cmax will be summarized as the mean and standard deviation for all participants.

  2. Mean minimum observed concentration (Cmin) of E2609 and metabolites on Day 1 and Day 14 [ Time Frame: Days 1 and 14: predose; 1, 2, 3, 4, 6, and 10 hours postdose ]
    Cmin is defined as the minimum observed concentration that a drug achieves in a specified compartment or test area of the body after the drug has been administered. Using non-compartmental analysis, plasma concentrations of E2609 and metabolites will be analyzed to determine Cmin. Cmin will be summarized as the mean and standard deviation for all participants.

  3. Median time from dosing to reach Cmax (tmax) of E2609 and metabolites on Day 1 and Day 14 [ Time Frame: Days 1 and 14: predose; 1, 2, 3, 4, 6, and 10 hours postdose ]
    Tmax is defined as the time from dosing to reach the maximum observed concentration a drug achieves in a specified compartment or test area of the body after the drug has been administered. Using non-compartmental analysis, plasma concentrations of E2609 and metabolites will be analyzed to determine Tmax. Tmax will be summarized as the median for all participants.

  4. Mean area under the concentration-time curve (AUC) from time 0 to 24 hours for E2609 and metabolites on Day 1 and Day 14 [ Time Frame: Days 1 and 14: 1, 2, 3, 4, 6, 10, and 24 hours postdose ]
    AUC represents the total drug exposure over a defined period of time. Plasma concentrations of E2609 and its metabolites will be analyzed using a non-compartmental analysis approach to determine individual participant estimates of AUC(0-24h). AUC(0-24h) will be summarized as the mean and standard deviation for all participants and will be expressed in nanograms x hour per milliliter (ng*hr/mL).

  5. Mean terminal elimination half-life (t1/2) following the last day of dosing (Day 14) of E2609 and metabolites [ Time Frame: Day 14: 1, 2, 3, 4, 6, 10, 24, 48, 72, 96, and 144 hours postdose ]
    Terminal half-life is the time it takes for a substance to lose half of its pharmacologic, physiologic, or radiologic activity. Plasma concentrations of E2609 and its metabolites will be analyzed using a non-compartmental analysis approach to determine t1/2. t1/2 will be summarized as the mean and standard deviation for all participants and will be expressed in hours.

  6. Mean average concentration calculated as AUCss/tau (Css,av), where tau is the dosing interval, of E2609 and metabolites on Day 1 and Day 14 [ Time Frame: Days 1 and 14: 1, 2, 3, 4, 6, 10, and 24 hours postdose ]
    Css,av is the average steady-state concentration of a drug. Steady state will be achieved when the rate of E2609 administration and the rate of E2609 elimination are equal. Plasma concentrations of E2609 and its metabolites will be analyzed using a non-compartmental analysis approach to determine the Css,av.

  7. Mean accumulation ratio for AUC, Cmax, and Cmin (Rac) for E2609 and metabolites on Day 1 and Day 14 [ Time Frame: Days 1 and 14: 1, 2, 3, 4, 6, 10, and 24 hours postdose ]
    Rac is equal to the ratio of the AUC during a dosage interval at steady state to the AUC of a dosage interval after the first dose. Plasma concentrations of E2609 and its metabolites will be analyzed using a non-compartmental analysis approach to determine Rac. Rac will be summarized as the mean and standard deviation for all participants

  8. Apparent clearance at steady state (CLss/F) of E2609 on Day 14 [ Time Frame: Day 14: 1, 2, 3, 4, 6, 10, 24, 48, 72, 96, and 144 hours postdose ]
    CLss/F is the rate and extent of absorption and clearance of E2609 from the plasma. Plasma concentrations of E2609 and metabolites will be analyzed using a non-compartmental analysis approach to determine CLss/F.

  9. Number of participants with polymorphisms of N-acetyltransferase 2 (NAT2) [ Time Frame: Day 1 ]
    NAT2 genotyping will be conducted, and the predicted phenotype (eg, slow, intermediate, or rapid acetylators) will be used in the statistical analysis to evaluate the relative impact of NAT2 polymorphisms on plasma concentrations of E2609 and/or its metabolites.
