Medical conditions in swallowing, malabsorption, or other chronic gastrointestinal disease that may hamper compliance and/or absorption of the investigational agent. 5. During the study period, drugs that may prolong the QT (such as anti arrhythmic drugs) could not be interrupted. 6. Evidence of central nervous system involvement of the malignancy, including invasion of brain parenchyma and meninges, or spinal cord compression. 7. Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy(such as pneumonia). 8. Active infection with hepatitis B and C virus ( Volunteers with HBsAg or HBcAb positive and HBV-DNA greater than or equal to 1000 coRpies/ml or 200IU/ml; HCV antibody and HCV-RNA positive ). 9. History of immune deficiency ( acquired or congenital ), or history of organ transplantation, or allogeneic bone marrow or hematopoietic stem cell transplantation. 10. Presence of severe or uncontrolled cardiovascular disease. 11. The baseline pregnancy test was positive in pregnant women, lactating women or fertile women. 12. According to the judgement of the investigator, there are concomitant diseases that seriously endanger the safety of patients or affect the completion of the study (such as severe hypertension, diabetes, thyroid diseases, etc.). 13. Medical history of other primary malignant tumors in the past 5 years except for the following: clinically cured cervical in situ, local basal cell carcinoma of the skin.
