4. Allow radiation therapy outside the chest (ie, bone metastases) for the purpose of palliative care;
5. Etoposide + platinum (cisplatin or carboplatin) received major surgery within 28 days before the first dose (defined by the investigator). Note: For the purpose of palliative care, local surgery on isolated lesions is acceptable;
6. Patients with symptomatic brain metastases;
7. People with hypertension who cannot be well controlled by a single antihypertensive drug (systolic blood pressure>140 mmHg, diastolic blood pressure>90 mmHg);

Patients who have previously had HBV infection or have been cured (defined as the presence of hepatitis B core IgG antibodies and the absence of HBsAg) are eligible. Hepatitis C virus (HCV) antibody-positive patients are only eligible if the HCV RNA polymerase chain reaction is negative;

14. Those who have received live vaccination within 4 weeks before the start of treatment;
15. Patients requiring renal dialysis;
16. Those who had suffered from tumors other than small cell lung cancer within 5 years before being enrolled in this study. Except: cervical carcinoma in situ, cured basal cell carcinoma, cured bladder epithelial tumor;
17. Arteriovenous thrombosis events occurred within one year before screening, such as cerebrovascular accidents (including temporary ischemic attacks), deep vein thrombosis and pulmonary embolism, etc.;
18. Pulmonary hemorrhage ≥ CTCAE grade 2 occurred within 4 weeks before the first use of the study drug;
