   • In the case of > 1.5 times the upper limit of Total bilirubin normal range in the blood
   • Estimated Global Film Rate (eGFR) <60 mL/min/1.73 m2 using the Modification of Diet in Regular Disease (MDRD) formula
   • Serum test (hepatitis B test, hepatitis C test, human immunodeficiency virus (HIV) test, syphilis test) result are positive factors
   • QTcF > 480 msec on electrocardiogram
   • After resting for at least 5 minutes, those who showed a value corresponding to systolic blood pressure>150 mmHg or <90 mmHg, diastolic blood pressure>100 mmHg or <50 mmHg in the vital signs measured at the seat

5. A person who shows suspected symptoms of acute illness (chilliness, fever, diarrhea, stomatitis, redness, infectious symptoms, etc.) at the time of screening tests.

6. A person who has a history of drug abuse or has tested positive in a urine drug screening test within one year of screening.
