A history or complication of malignant tumor, lymphoma, leukemia, or lymphoproliferative disorder, a clinically significant disease requiring treatments within 8 weeks before the investigational product treatment, or a history of a clinically significant infection within 4 weeks before the investigational product treatment 3. With a psychiatric, digestive, hepatic, renal, respiratory, endocrine, hematologic, neural, or cardiovascular disease within 4 weeks before the investigational product treatment, a congenital metabolic abnormality, or otherwise a disease that may affect the drug assessments 4. With a surgical history (e.g., resection of the liver, kidney, or digestive tract, etc.) at screening that may affect the pharmacokinetics of the investigational product 5. Suspicion of having a clinically abnormal symptom or an organ impairment that requires treatments based on the history/complications at screening or physical findings, vital signs, electrocardiogram findings, or laboratory values at screening or baseline 6. Testing positive for human immunodeficiency virus (HIV) at screening 7. A positive response to a qualitative test for hepatitis B virus surface antigen (HBs antigen), hepatitis B virus core antigen (HBc) antibody, hepatitis C virus (HCV) antibody, or syphilis 8.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Volume of Distribution (Vd) of E3112 | Day 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. |
| Serum Concentrations of E3112 | Day 1: 0-24 hours; Day 8: 0-24 hours | — |
| Change from Baseline in Serum Concentration of E3112 | Day 1: 0-24 hours; Day 8: 0-24 hours | — |
| Peak Concentration (Cmax) of E3112 | Day 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 E3112 | Day 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 E3112 | Day 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 E3112 | Day 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 E3112 | Day 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 E3112 | Day 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. |
