You may be eligible if
1. Male or female, age greater than or equal to (\>=) 18 years at the time of informed consent
2. Diagnosis of NT1 defined by the following criteria:
* History of daily periods of the irrepressible need to sleep, or daytime lapses into sleep, occurring for at least 3 months
* History of cataplexy (which must be confirmed during the Screening Period by Sleep/Cataplexy Diary)
* At least one of the following:
* On Screening multiple sleep latency test (MSLT): MSL of less than or equal to (\<=) 8 minutes and 2 or more sleep onset rapid eye movement periods (SOREMPs) on an MSLT performed according to standard techniques
* On Screening nocturnal polysomnography (PSG): One or more SOREMPs within 15 minutes of sleep onset
3. Epworth Sleepiness Scale score \>=10
4. Reports regular bedtime, defined as the time that the participant attempts to sleep, between 22:00 and midnight (based on data from the Screening Sleep/Cataplexy Diary)
5. Reports regular waketime, defined at the time the participant gets out of bed for the day, between 05:00 and 10:00 (based on data from the Screening Sleep/Cataplexy Diary)
6. Reports being in bed between 7 and 9 hours per night (based on data from the Screening Sleep/Cataplexy Diary)
7. Body mass index (BMI) \>=18 to less than (\<) 40 kilograms per meter square (kg/m\^2), at Screening
You may not be if
1. 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 \[or hCG\]), and females who are breastfeeding or pregnant during the Treatment Period. A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the 1st dose of study drug
2. Females of childbearing potential who:
* Within 28 days before study entry, did not use a highly effective method of contraception, which includes any of the following:
* total abstinence (if it is their preferred and usual lifestyle)
* a nonhormonal intrauterine device (example, "coil") or a progesterone-only intrauterine hormone-releasing system
* a nonsteroidal oral contraceptive (participant must have been on a stable dose of the same nonsteroidal oral contraceptive product for at least 28 days before dosing and must agree to stay on the same dose of the oral contraceptive throughout the study and for 28 days after study drug discontinuation.)
* depot medroxyprogesterone acetate or depot norethisterone enantate.
* have a vasectomized partner with confirmed azoospermia.
* Do not agree to use a highly effective method of contraception (as described above) throughout the entire study period and for 30 days after study drug administration.
* Participants on an oral contraceptive must use an additional barrier method throughout the study and for 30 days after study drug administration.
NOTE: All females will be considered to be of childbearing potential unless they are postmenopausal (amenorrheic for at least 12 consecutive months, in the appropriate age group, and without other known or suspected cause) or have been sterilized surgically (that are, bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month before dosing).

8. Hypersensitivity to excipients of the study drug (E2086), or to active comparator or any of its excipients
9. Any suicidal ideation with intent with or without a plan at Screening or within 6 months of Screening (that is, answering "Yes" to questions 4 or 5 on the Suicidal Ideation section of the CSSRS)

14. Psychotic disorder(s) or unstable recurrent affective disorder(s) evident by use of antipsychotics within 2 years before Screening

16. Any clinically abnormal symptom or organ impairment found by medical history, physical examinations, vital signs, ECG finding, or laboratory test results that require medical treatment at Screening or Baseline
17. Any history of or concomitant medical condition that in the opinion of the investigator(s) would compromise the participant's ability to safely complete the study.
18. History of drug or alcohol dependency or abuse within 2 years before Screening
19. Use of illegal recreational drugs at Screening and throughout the study
20. Intake of herbal preparations containing St. John's Wort within 4 weeks before dosing
