- •Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) <2.5 × ULN, with liver metastasis <5 × ULN
- •international normalized ratio (INR) <1.5
- •Has a life expectancy of at least 12 weeks

- •If patient has chronic hepatitis B infection and is receiving antiviral treatment, has a negative viral load at Screening.
- •Is willing and able to comply with all protocol required visits and assessments
排除标准
- •Is unable to take oral medication or malabsorption syndromes potentially interfering with medication absorption (e.g., short bowel syndrome or chronic, partial bowel obstruction)
- •Has history or presence of clinically significant abnormal 12 lead ECG results, in the investigator's opinion
- •Has current brain metastasis
