11. ECOG score: 0 \~ 1;
12. The expected survival time is ≥12 weeks;
13. The main organ functions meet the following requirements (within 7 days before the start of the study and treatment):

14. If the patient suffers from active hepatitis B virus (HBV) infection, the HBV- deoxyribonucleic acid (DNA) must be less than 500 IU/mL (if the research center only has a copy/mL detection unit, it must be less than 2500 copy/mL), and he must receive anti-HBV treatment (according to local standard treatment, such as entecavir) for at least 14 days before the start of the research treatment, and he is willing to take the whole course during the research period.
