NCT02039089

Brief Summary

This study will be a single-center, multiple-dose, randomized, double-blind, placebo-controlled, parallel-group study in healthy male and female subjects. The study will consist of 2 parts: Part A (3 cohorts of healthy Japanese subjects dosed in the evening) and Part B (one cohort of healthy white subjects dosed in the evening). The cohorts will be conducted sequentially. Part A will be started first with the 2.5-mg dose cohort, followed by the 10-mg dose cohort and then the 25-mg dose cohort. Part B will be conducted in parallel with the 10-mg cohort of Part A, with the possibility of overlap.

Outcome Measures

Primary Outcomes (7)

  • Pharmacokinetic (PK) profiles of E2006

    The primary PK parameters are Cmax, tmax, AUC(0-T), AUC(0-24h), and t1/2, derived by non-compartmental analyses using the plasma concentration of E2006 and metabolites (as data permit).

    Up to 49 days

  • Pharmacodynamic (PD) profile of E2006

    acute effects of E2006 on sleepiness in the hour before bedtime as well as next-day residual sleepiness throughout the daytime hours subsequent to each dose using the KSS and PVT. Effects of E2006 on nighttime sleep will be evaluated using PSG. High-precision QT analyses (HPQT) will be performed using data from 24-hour Holter recordings. The time points of Holter readings will be corresponding to the PK time points.

    Up to 49 days

  • Adverse events (AEs ) as a measure of safety and tolerability

    Up to 49 days

  • Suicidality as a measure of safety and tolerability

    Measured by the columbia suicide severity rating scale (C-SSRS)

    Up to 49 days

  • Vital signs as a measure of safety and tolerability

    Vital sign measurements will include systolic and diastolic blood pressure (BP) and pulse rate

    Up to 49 days

  • Electrocardiogram (ECG) as a measure of safety and tolerability

    Twelve-lead ECGs will be obtained as a measure of safety and tolerability

    Up to 49 days

  • Laboratory assessments as a measure of safety and tolerability

    Up to 49 days

EXPERIMENTAL

Part A: dose escalation of E2006 in Japanese subjects from 2.5 mg (1 x 2.5-mg tablet) up to 10 mg (1 x 10-mg tablet) then to 25 mg (2 x 10-mg tablet, 1 x 5-mg tablet).

  • Who report typical sleep latency of less than or equal to 30 minutes.
  • With typical total sleep time greater than or equal to 420 minutes.
  • Body mass index (BMI) greater than or equal to 18 and less than or equal to 28 kg/m2 at Screening.

You may not qualify if:

  • Subjects who meet any of the following criteria will be excluded from this study:
