• Males who have not had a successful vasectomy (confirmed azoospermia) or they and their female partners do not meet the criteria above (i.e., not of childbearing potential or practicing highly effective contraception throughout the study period or for 28 days after study drug discontinuation). No sperm donation is allowed during the study period or for 28 days after study drug discontinuation.
• Evidence of disease that may influence the outcome of the study within 4 weeks prior to the first dose (e.g., psychiatric disorders and disorders of the gastrointestinal tract, liver, kidney, respiratory system, endocrine system, hematological system, neurological system, or cardiovascular system, or participants who have a congenital abnormality in metabolism)
• Any history of abdominal surgery that may affect pharmacokinetic profiles of E2027 (e.g., hepatectomy, nephrectomy, digestive organ resection). Participants with a history cholecystectomy or appendectomy are not excluded.
• Any other clinically abnormal symptom or organ impairment found by medical history, physical examinations, vital signs, electrocardiogram (ECG) finding (including a PR greater than 210 milliseconds (msec), a QRS greater than 110 msec), or laboratory test results that requires medical treatment at Screening or Baseline as determined by the Principal Investigator or designee
• A prolonged QT/QTc interval (QTc greater than 450 msec) demonstrated on ECG at Screening or Baseline (based on average of triplicate ECGs). A history of risk factors for torsade de pointes (e.g., heart failure, hypokalemia, family history of long QT Syndrome) or the use of concomitant medications that prolonged the QT/QTc interval
• Left bundle branch block at Screening or Baseline
• Persistent systolic blood pressure (BP) greater than 160 or less than 100 millimeters of mercury (mmHg) or diastolic BP greater than 100 or less than 50 mmHg at Screening or Baseline
• Persistent pulse rate less than 50 beats/minute (min) or more than 90 beats/min at Screening or Baseline
• History of myocardial infarction, ischemic heart disease, or cardiac failure at Screening
• History of clinically significant arrhythmia or uncontrolled arrhythmia
