- Sign the informed consent form before the trial and be able to complete the study as required by the trial protocol.
You may not qualify if…

- Presence of gastrointestinal impairment or gastrointestinal disease that may affect the absorption of oral medication in the judgment of the investigator, such as severe gastrointestinal diseases (peptic ulcer, erosive or atrophic gastritis), partial gastrectomy, Grade > 2 gastrointestinal symptoms at screening (e.g., nausea, vomiting, or diarrhea), etc.;
- Concurrent severe diseases of the circulatory, respiratory, urinary, hematologic, metabolic, immune, psychiatric, neurological, renal, or other systems, rendering the subject unsuitable for participating in the study as determined by the investigator.
