Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum plasma concentration (Cmax) of Lacosamide (LCM) | Blood samples will be taken at indicated time points to determine maximum Lacosamide (LCM) plasma concentration. | Blood samples are collected at predose and 0.25, 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, 48, and 72 hours after dosing | 
| Area under the LCM plasma concentration-time curve from time zero up to the time of last quantifiable concentration (AUC[0-t]) | Area under the LCM plasma concentration-time curve from time zero up to the last quantifiable concentration data point, computed using the log-linear trapezoidal rule. | Blood samples are collected at predose and 0.25, 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, 48, and 72 hours after dosing | 
| Area under the LCM plasma concentration-time curve extrapolated to infinity (AUC) | Area under the LCM plasma concentration-time curve extrapolated to infinity calculated as AUC(0-t) + t/z, where t is the estimated plasma concentration at time t and z the terminal elimination rate constant. | Blood samples are collected at predose and 0.25, 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, 48, and 72 hours after dosing | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Terminal plasma elimination half-life (t1/2) of LCM | Terminal elimination half-life of LCM, reported in hours, as determined via simple linear regression(slope=-z) of natural log (ln) concentration vs time for data points in the terminal phase of the concentration-time curve. t½ is calculated as ln(2)/z. | Blood samples are collected at predose and 0.25, 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, 48, and 72 hours after dosing | 
| Time of observed Cmax (tmax) of LCM | Time of observed Cmax will be obtained directly from the plasma concentration-time curves. | Blood samples are collected at predose and 0.25, 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, 48, and 72 hours after dosing | 
| Apparent plasma clearance (CL/F) of LCM | Apparent plasma clearance calculated as CL/F=Dose/AUC. | Blood samples are collected at predose and 0.25, 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, 48, and 72 hours after dosing | 
| Apparent volume of distribution (Vz/F) of LCM | Apparent volume of distribution, calculated as Vz/F=(CL/F)/z. | Blood samples are collected at predose and 0.25, 0.5, 1.0, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, 48, and 72 hours after dosing |
