Primary Outcome Measures
NameTimeMethod
Area under the curve (AUC)Days 1 to 4, 8, 14, and 28

AUC is the area under the curve in a plot of concentration of drug in blood plasma against time. AUC represents the total drug exposure over a defined period of time.

Half-life of elimination (t1/2) of E3112Days 1 to 4, 8, 14, and 28

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

Clearance of E3112Days 1 to 4, 8, 14, and 28

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

Peak concentration (Cmax) of E3112Days 1 to 4, 8, 14, and 28

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 E3112Days 1 to 4, 8, 14, and 28

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.

Volume of distribution (Vd) of E3112Days 1 to 4, 8, 14, and 28

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.

Secondary Outcome Measures
NameTimeMethod
Number of participants with an abnormal, clinically significant vital sign measurementBaseline; Days 1 to 28

Clinical significance will be determined by the investigator.

Number of participants with an abnormal, clinically significant physical examination measurementBaseline; Days 1 to 28

Clinical significance will be determined by the investigator.

Number of participants with an abnormal, clinically significant hematology parameter valueDays 1 to 28

Clinical significance will be determined by the investigator.

Number of participants with any serious adverse event and any non-serious adverse eventDays 1 to 28

An adverse event is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. A serious adverse event is defined as any adverse event occurring at any dose that results in any of the following outcomes: results in death; is life threatening; results in inpatient hospitalization or prolongation of existing hospitalization; results in a persistent or significant incapacity or substantial disruption of the ability to conduct normal life function; results in a congenital anomaly/birth defect; or can be defined as any other important medical event.

Number of participants with an abnormal, clinically significant blood chemistry parameter valueDays 1 to 28

Clinical significance will be determined by the investigator.

Number of participants with an abnormal, clinically significant urine valueDays 1 to 28

Clinical significance will be determined by the investigator.

Number of participants with an abnormal, clinically significant electrocardiogram (ECG) measurementBaseline; Days 1 to 28

Clinical significance will be determined by the investigator.
