5. History of significant allergy or intolerance to any drug, food, or other substance.
6. History of any clinically significant disease in the neurological, cardiovascular, digestive, respiratory, urinary, endocrine, hematological, immune systems, or any other disease or condition that the investigator believes may affect the trial results.
7. History of surgery that may affect drug absorption, distribution, metabolism, or excretion, or plans for surgery or other reasons requiring hospitalization during the expected study period.
8. Uncontrolled bacterial, viral, parasitic, or fungal infection requiring treatment at the time of screening (except Hepatitis B), or history of severe active infection within 1 month prior to screening.

11. Use of traditional Chinese medicine (herbal medicines, proprietary Chinese medicines), dietary supplements, or vitamins within 14 days prior to study drug administration.
12. Systemic use of moderate or potent CYP3A4 inhibitors (e.g., itraconazole, fluconazole) or moderate or potent CYP3A4 inducers within 14 days prior to study drug administration.
13. Positive urine drug screen or alcohol breath test at screening.
