If dipstick is ≥2+ then a 24-hour urine collection can be done and the patient may enter only if urinary protein is <2 g per 24 hours；Women of childbearing potential must have a negative serum or urine pregnancy test are received within 7 days before the randomization.

The baseline systolic blood pressure readings must be ≤140, and the baseline diastolic blood pressure readings must be ≤90. Patients whose hypertension is controlled by antihypertensive therapies are eligible

5. Prior therapy with VEGFR-target TKI included anlotinib or an anti-programmed cell death (PD)-1, anti-PD-L1, anti-PD-L2, anti-tumor necrosis factor CD137, or anti-cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) antibody ,or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways. Previous treatment with anti-angiogenesis agents including thalidomide, or inhibitors of epidermoid growth factor (EGF), platelet derived growth factor (PDGF), or fibroblast growth factors (FGF) receptors.
6. Any other form of systemic or local antitumor therapy is planned for the duration of the study.
7. Immunosuppressive therapy with immunosuppressive agents or systemic or absorbable local hormones (dosage > 10 mg/day prednisone or other therapeutic hormones) is required for the purpose of immunosuppression, and is still in use for 2 weeks after the first administration.
8. Has diagnosed and/or treated additional malignancy within 5 years prior to randomization. Exceptions include cured basal cell carcinoma of skin and carcinoma in situ of cervix.

9. Has brain metastasis and cancerous meningitis during screening . Active autoimmune disease（Such as the following, but not limited to: autoimmune hepatitis interstitial pneumonia enteritis vasculitis, nephritis。Subjects with asthma requiring bronchodilators for medical intervention were not included） requiring systemic treatment（Such as the use of palliative drugs, corticosteroids, or immunosuppressants） occurred within 2 years prior to initial administration.

12. Subjects with poor blood pressure control (systolic≥ 150 mmHg or diastolic ≥100mmHg)
13. Has multiple factors affecting oral medication or malabsorption syndromes.
14. Has uncontrollable pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures.
15.

19. According to the judgement of the researchers, there are other factors that may lead to the termination of the study. For example, other serious diseases including mental disorders need to be treated together, serious laboratory abnormalities, accompanied by family or social factors, which will affect the safety of the subjects, or the collection of data and samples.
