Bioavailability and Food Effect Study of Cenobamate as an Oral Suspension and Tablet
Study Details
Study Description
Brief Summary
This study is designed to evaluate the relative bioavailability, or the degree and rate at which the drug is absorbed by the body of two cenobamate formulations (200 mg Oral Suspension and a 200 mg Oral Tablet) and to assess the effect of food on the oral bioavailability of the 200 mg Oral Suspension. This study will also look at the safety and tolerability of the oral suspension and the oral tablet under both fasted and fed conditions.

| Phase 1 |
Detailed Description
This study is an open-label, randomized, single-dose, single-center, three-period, six-sequence, balanced crossover study in healthy male and female subjects to assess the relative bioavailability of 200 mg of cenobamate given as an oral tablet or oral suspension and to evaluate the effect of food on the bioavailability of a 200 mg dose of cenobamate given as an oral suspension in fasting and fed conditions.
The study consists of a 28-day screening period, followed by single dose administration of cenobamate (tablet or suspension) on Day 1, Day 22, and Day 43, an assessment period of 62 days and a follow-up visit on Day 69. All subjects will be confined to the clinical site from Day -1 (the day before period 1 dosing) until the morning of Day 4, Day 20 (the day of the last PK sampling for period 1) until the morning of Day 25, and Day 41 (the day of the last PK sampling for period 2) until the morning of Day 46. Outpatient visits will be performed regularly until the 456-hour PK sampling for each period. The follow-up visit will occur on Day 69 (±1 day).

Outcome Measures
Primary Outcome Measures
- Cmax [69 days]
Maximum observed plasma concentration of cenobamate
- tmax [69 days]
Time to reach Maximum observed plasma concentration of cenobamate
- Area Under the Concentration Curve to last measurable concentration [up to 69 days]
AUC from the time of dosing to the time of the last measurable concentration of cenobamate
- Area Under the Concentration Curve from 0 to infinity [up to 69 days]
AUC from time 0 extrapolated to infinity
Secondary Outcome Measures
- Incidence of Treatment-Emergent Adverse Events [Up to 69 days]
To evaluate the safety and tolerability of each cenobamate formulation administered under either fed (Oral Dose of cenobamate administered at a single 200 mg/20 mL suspension ) or fasted (Both tablet and oral suspension formulations) incidence of treatment-emergent adverse events will be monitored.
- Risk of Suicidality [Up to 69 days]
Subjects will be assessed on the risk for suicidality via the Columbia Suicide Severity Rating Scale
