Primary Outcome Measures
NameTimeMethod
Serum Concentrations of E3112Day 1: 0-24 hours; Day 8: 0-24 hours
Change from Baseline in Serum Concentration of E3112Day 1: 0-24 hours; Day 8: 0-24 hours
Peak Concentration (Cmax) of E3112Day 1: 0-24 hours; Day 8: 0-24 hours

Cmax is the maximum observed concentration that a drug achieves in a specified compartment or test area of the body after the drug has been administered.

Time to Peak Concentration (Tmax) of E3112Day 1: 0-24 hours; Day 8: 0-24 hours

Tmax is the time from dosing to reach the maximum observed concentration a drug achieves in a specified compartment or test area of the body after the drug has been administered.

Area Under the Concentration-time Curve (AUC 0-t) of E3112Day 1: 0-24 hours; Day 8: 0-24 hours

AUC 0-t is area under the concentration-time curve from time 0 to time of last quantifiable concentration for E3112.

Area Under the Concentration-time Curve (AUC∞) of E3112Day 1: 0-24 hours; Day 8: 0-24 hours

AUC∞ is area under the concentration-time curve from time 0 to infinity of E3112.

Half-life of Elimination (t1/2) of E3112Day 1: 0-24 hours; Day 8: 0-24 hours

t1/2 is the time required for the concentration of the drug to reach half of its original value.

Clearance (CL) of E3112Day 1: 0-24 hours; Day 8: 0-24 hours

CL is defined as the rate of drug elimination divided by the plasma concentration of the drug.

Volume of Distribution (Vd) of E3112Day 1: 0-24 hours; Day 8: 0-24 hours

Vd is the theoretical volume that would be necessary to contain the total amount of an administered drug at the same concentration that it is observed in the blood plasma.
