11. History or evidence of drug addict or investigation with urine sample shows a positive
test for drug of abuse (morphine, marijuana or methamphetamine).
12. Have sitting systolic blood pressure of less than 90 mmHg or more than 139 mmHg and
diastolic blood pressure of less than 60 mmHg or more than 89 mmHg on screening day
and on the check-in day. If abnormal blood pressure detects, the measurement should be
repeated two more times after taking a rest for at least 5 minutes each. The last
measurement value should be used to determine the subject's eligibility.
13. Investigation of vital signs shows pulse rate less than 60 or more than 100 beats per

measurement should be repeated two more times after taking a rest for at least 5
minutes each. The last measurement value should be used to determine the subject's
eligibility.
14. 12-lead ECG demonstrating QTc >450 msec, a QRS interval >120 msec or with an
abnormality considered clinically significant at screening. If QTc exceeds 450 msec,
or QRS exceeds 120 msec, the ECG will be repeated two more times and the average of
the three QTc or QRS values will be used to determine the subject's eligibility.

16. Abnormal liver function, =1.5 times of upper normal limit of reference range for ALT,
AST or bilirubin levels at screening laboratory test.
17. Have eGFR (CKD-EPI) < 30 mL/min/1.73 m2 based on serum creatinine results, at the

19. History or evidence of alcoholism or harmful use of alcohol (less than 2 years) i.e.,

abstain for at least 48 hours prior to check-in in Period 1 and continued for entire
duration of the study or alcohol breath test shows positive result. In case of alcohol
breath test result represents the alcohol concentration range of 1 - 10 mg% BAC and
the physician carefully considers that the value came from other reasons, not from the
alcohol drinking behavior of subjects, the test will be repeated two times separately,
not more than 10 minutes. The result of the last time should be used for subject's
eligibility which must be 0 mg%BAC.
21. History or evidence of habitual consume of tea, coffee, xanthine or caffeine
