6. History or presence of hepatic, renal, cardiovascular, neurological, psychiatric, psychological or immunological disorders.

7. Clinically significant abnormalities in physical examination, vital signs, laboratory tests, or 12-lead ECG at screening, and investigators consider that these abnormalities may affect participant's safety or study results. ECG abnormalities including but not limited to: second- or third-degree atrioventricular block; long QT syndrome or QTcF > 450 ms (males) or > 470 ms (females). (If the QTcF > 450 ms (males) or > 470 ms (females), two additional ECG measurements should be repeated, and the mean of the three values should be used to determine the participant's eligibility.); left bundle branch block;Wolff-Parkinson-White syndrome; Or other clinically significant 12-lead ECG abnormalities requiring treatment.

8. Use of any prescription or over-the-counter (OTC) medications, traditional Chinese medicine within 12 months prior to screening that may confound PK, PD, or safety assessments.

16. Major surgery within 4 weeks prior to screening, or planned major surgery during the study.

17. Participant with systolic blood pressure (SBP) < 90 mmHg or > 140 mmHg, or diastolic blood pressure (DBP) < 50 mmHg or > 90 mmHg after resting in a sitting position, or heart rate (HR) < 50 beats per minute (BPM) or > 100 bpm at rest in sitting position at the screening.

18. Any other factors that may affect participation in this study at the discretion of the investigator.
