About this trial
The primary purpose of this study is to assess potential drug-drug interactions of E2086 when coadministered orally with Itraconazole, Carbamazepine, Midazolam, Dextromethorphan, Bupropion, or Combined Oral Contraceptives in Healthy Participants
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Body Mass Index (BMI) greater than or equal to (≥) 18 and less than (<) 30 kilograms per square meter (kg/m2) at Screening
Non-smoking and non-vaping, healthy male or female, age ≥18 years and ≤55 years old at the time of informed consent (only Parts A and B).
Non-smoking and non-vaping, healthy female, age ≥18 years and ≤55 years old at the time of informed consent (only Part C).
Disqualifiers
Females who are breastfeeding or pregnant at Screening or Baseline (as documented by a positive beta-human chorionic gonadotropin [ß-hCG] or human chorionic gonadotropin [hCG] test with a minimum sensitivity of 25 international units per liter (IU/L) or equivalent units of ß-hCG or hCG). 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
