A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the first dose of study drug.
• Males who have not had a successful vasectomy (confirmed azoospermia) or they and their female partners do not meet the criteria (i.e., not of childbearing potential or practicing highly effective contraception throughout the study period or for 5 times the half-life of the study drug plus 90 days after study drug discontinuation). No sperm donation is allowed during the study period and for 5 times the half-life of the study drug plus 90 days after study drug discontinuation.
• Participants with history of seizures, including those experienced in childhood
• Any history of gastrointestinal surgery that may affect pharmacokinetic profiles of E2730, e.g., hepatectomy, nephrectomy, and digestive organ resection
• A prolonged QT/QTc interval (QTcF >450 milliseconds) demonstrated by a repeated 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
• Persistent systolic blood pressure (BP) >139 or <90 millimeters of mercury (mmHg) or diastolic BP >89 or <50 mmHg at Screening or Baseline

• History of drug or alcohol dependency or abuse, or those who have a positive drug test at Screening or Baseline
• Currently enrolled in another clinical study or used any investigational drug or device within 28 days or 5 half-lives, whichever is longer, preceding informed consent
• Participants who undergo blood transfusion within 12 weeks, or who donate 400 milliliters (mL) or more of whole blood within 12 weeks or 200 mL or more of whole blood within 4 weeks, or who make a component donation within 2 weeks prior to dosing
