   * 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.
7. If the tester determines that the following drugs, excluding topical drugs without significant systemic absorption, may affect this test or affect the safety of the test subject within the relevant period.
