5. Is considered incurable by local therapies;
6. Have measurable disease based on RECIST1.1. tumor lesions, situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesion after 3 months of radiotherapy;
7. Have provided tissue for PD-L1 biomarker analysis
8. The estimated survival period is ≥ 3 months;

9. Laboratory inspection:

   Blood routine: neutrophils ≥1.5×l09/L, platelets≥75×109/L, hemoglobin≥80g/L; Liver function: alanine aminotransferase (ALT) and aspartate aminotransferase (AST), ALT and AST ≤ upper limit of normal value × 3 for liver metastasis, ALT and AST ≤ upper limit of normal value for liver metastases × 5; total bilirubin ( TBIL) ≤ upper limit of normal value × 1.5; Renal function: creatinine (Cr) ≤ normal upper limit × 1.5; Coagulation: Activated Partial Thromboplastin Time (aPTT), International Normalized Ratio (INR), Prothrombin Time (PT) ≤1.5xULN Echocardiogram: LVEF≥50%

10. Subjects should agree to use an adequate method of contraception starting with the first dose of study medication through 6 months after the last dose of study therapy.
