Before entering the study, subject must have completed radiotherapy or CNS tumor metastasis surgery for more than fourteen days, neurological function must be in a stable state with no new neurological defects found in the clinical examination and no new problems found in the CNS imaging examination. If necessity arises for subjects to use steroids for CNS metastases treatment, said steroid treatment dose must have reached stable treatment for ≥ 3 months at least two weeks before entering the study. 6. Current uncontrollable third cavity effusion, such as a large amount of pleural effusion or ascites. 7. Unmeet the inclusion criteria of sub scheme. 8. Major surgical operations or incomplete healing of injury within 28 days prior to study treatment's first administration and chest radiotherapy of \> 30 Gy within 6 months. 9. History of receiving other investigational drugs within 14 days or 5 half-lives (whichever is longer) prior to the first administration. 10. History of receiving live vaccine within 30 days prior to the first administration. Seasonal influenza vaccines that do not contain live viruses are allowed. 11. History of hypersensitivity to the active ingredients or non-active excipients of the study drug, hypersensitivity to drugs with chemical structure similar to the study drug or hypersensitivity to similar drugs of the study drug. 12. Current active infection requiring systemic treatment (antibiotics); or any of the following: 1. HIV positive or known history of acquired immunodeficiency syndrome; 2. Hepatitis B virus (HBV) or hepatitis C virus (HCV) infection is defined as HBsAg positive and the number of HBV DNA copies exceeds the upper limit of normal value, or HCV AB positive; 3. Active tuberculosis (with exposure history or positive tuberculosis test; with clinical and / or imaging manifestations); 4. Positive antibody of Treponema Pallidum. 13. Current evidenced uncontrollable systemic diseases (such as severe mental, neurological, epilepsy or dementia, unstable or uncompensated respiratory, cardiovascular, liver or kidney diseases, uncontrolled hypertension \[i.e., still greater than or equal to CTCAE Grade 3 hypertension after drug treatment\]). 14. History of myocardial infarction, coronary artery / peripheral artery bypass or cerebrovascular accident within 3 months. 15. Diagnosed with a second type of malignant tumor within 5 years before the first diagnosis of a rare solid tumor (excluding completely resected basal cell carcinoma, bladder carcinoma in situ, cervical carcinoma in situ). 16. History of receiving of any organ transplantation, including allogeneic stem cell transplantation. Transplantation without immunosuppression (corneal transplantation, hair transplantation) is excluded. 17. Cardiovascular disease or symptom includes any of the following: 1. History of Congestive Heart Failure requiring treatment and of New York Heart Association class III / IV CHF (see Appendix 3) ; 2. Current ventricular arrhythmia requiring antiarrhythmic drugs treatment, or uncontrollable or unstable arrhythmia; 3. Severe conduction disorder (such as grade II or III AV block); 4. Angina requiring treatment; 5. QT interval (QTC) of 12 lead ECG is ≥ 450 ms in male and ≥ 470 MS in female; 6.

Platelet count \< 100 × 109 / L (transfusion dependent patients should be excluded from this study); 3. Hemoglobin \< 90g / L; 4. ALT is \> 2.5 x Upper Limit of Normal (ULN) If there is no clear liver metastases, ALT \> 5 x ULN if there is liver metastases; 5.
