4. Provide written informed consent
5. Willing and able to comply with all aspects of the protocol

Exclusion Criteria

1. Participated in a 14C research study within the 6 months prior to Day -2. The total radiation exposure to radiolabelled compounds from this study and any previous studies must be within the recommended levels considered safe (per US 21 CFR 361.1)
2. Exposure to clinically significant radiation (greater than 100 milliseiverts) within 12 months prior to Day -2
3. Any history of cerebrovascular disease (stroke or transient ischemic attack)
4. A prolonged QT/QTc interval (QTc greater than 450 msec) as demonstrated upon confirmatory ECG if first ECG indicates prolonged QT/QTc interval
5. History of prolonged QT/QTc interval
6. 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
7. Heart rate less than 40 or greater than 100 beats/min at Screening or Baseline
8. History of ischemic heart disease (e.g., acute coronary syndromes, stable angina), syncope or cardiac arrhythmias
9. Systolic blood pressure greater than 140 mmHg or less than 90 mmHg or diastolic blood pressure greater than 90 mmHg or less than 60 mmHg at Screening or Baseline
10. Hemoglobin less than 12.5 g/dL or hemotocrit less than or equal to 38% at Baseline check-in
11. Evidence of clinically significant disease (e.g., psychiatric disorders, disorders of the gastrointestinal tract, liver, kidney, respiratory system, endocrine system, hematological system, neurological system, or cardiovascular system) that in the opinion of the investigator(s) could affect the subject's safety or interfere with the study assessments
12. Any laboratory abnormalities considered clinically significant by the investigator
13. Clinically significant illness which required medical treatment within 8 weeks of dosing or a clinically significant infection within 4 weeks of dosing
14. Any history of gastrointestinal surgery (e.g., hepatectomy, nephrotomy, digestive organ resection) that may affect PK profiles of study drugs
15. Hypersensitivity to the study drug or any of its excipients
16. Known to be human immunodeficiency virus (HIV) positive or positive on viral screen for HIV or viral hepatitis B or hepatitis C
17. History of drug or alcohol dependency or abuse within approximately the last 2 years or who have a positive urine drug test or breath alcohol test at Screening or Baseline
18. Do not meet the restrictions on concomitant medications, food and beverages (see below)
19. Use of illegal (or legalized) recreational drugs in the past year
20. Engagement in strenuous exercise within 2 weeks prior to dosing (e.g., marathon runners, weight lifters)

21. Currently enrolled in another clinical trial or used any investigational drug or device within 30 days preceding informed consent

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pharmacokinetics: Excretion of E2006: urine/feces concentration	Total radioactivity derived from [14C]E2006-related material and E2006 will be analyzed in urine and feces. [14C]E2006 radiolabeled material will be quantified in urine and feces for total radioactivity using a scintillation counting method and/or an accelerator mass spectrometry.	Up to 35 days
Pharmacokinetics: Plasma concentration of E2006/metabolite	Total radioactivity derived from [14C]E2006-related material, E2006, and metabolites will be analyzed in whole blood, plasma, and red blood cells. [14C]E2006 radiolabeled material will be quantified in whole blood, plasma, red blood cells for total radioactivity using a scintillation counting method and/or accelerator mass spectrometry.	Up to 816 hours postdose

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pharmacokinetics: Metabolic profile of E2006: plasma/urine/feces concentration	Metabolite profiling in plasma, urine, and feces will be performed by radio-high performance liquid chromatography (radio-HPLC) methods. Metabolites will be identified on the radiochromatograms, and the amount of the each metabolite will be quantified based on the peak areas on the chromatograms. For metabolites detected on the radiochromatograms, LC/MS/MS analysis will be performed to estimate and identify their chemical structures.	Urine/Feces: Up to 35 days; Plasma: Up to 816 hours postdose
