• Brain metastases must have been asymptomatic or treated and stabilized after discontinuation of steroids and anticonvulsants for at least 1 month prior to study treatment;

• Patients of childbearing age (including female and female partners of male patients) must take effective birth control measures;

• Good compliance is expected, and the efficacy and adverse reactions can be followed up according to the protocol requirements.

Exclusion Criteria:

• Small cell lung cancer with other pathological types of tumors;

• Previously received anti-angiogenic drugs, including bevacizumab, sovanitinib, sunitinib, sorafenib, anlotinib, apatinib, etc.

• Receive the following treatments within the first 4 weeks of treatment, including but not limited to surgery, chemotherapy, radical radiotherapy, biotargeted therapy, immunotherapy, and other investigational drugs;

• Pregnant or lactating women;

• With pleural effusion or ascites, respiratory syndrome (≥CTC AE grade 2 dyspnea);

• Symptomatic brain or meningeal metastases (except those who have undergone local radiotherapy or surgery for brain metastases for more than 6 months and have stable disease control);

• Severe infection (e.g., intravenous infusion of antibiotics, antifungals, or antivirals) within 4 weeks prior to treatment, or unexplained fever > 38.5 ° C during screening/initial administration;

• Hypertension that is not well controlled with antihypertensive medication (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg)

• The urine routine indicated urinary protein ≥2+, and 24-hour urinary protein quantity >1.0g;

• Obvious clinical bleeding symptoms or obvious bleeding tendency within 3 months before treatment (bleeding > 30 mL within 3 months, hematemesis, melanism, blood in stool), hemoptysis (fresh blood > 5 mL within 4 weeks), etc. Or treatment for a venous/venous thrombotic event in the previous 6 months, such as a cerebrovascular accident (including transient ischemic attack, cerebral hemorrhage, cerebral infarction), deep vein thrombosis, and pulmonary embolism; Long-term anticoagulant therapy with warfarin or heparin or long-term antiplatelet therapy (aspirin ≥300 mg/day or clopidogrel ≥75 mg/day) is required;

• Active heart disease, including myocardial infarction and severe/unstable angina, developed 6 months before treatment. Echocardiography showed left ventricular ejection fraction < 50% and poor arrhythmia control (including QTcF interval, > 450 ms in men and > 470 ms in women).

• The patient had had other malignancies (except cured basal cell carcinoma of the skin and carcinoma in situ of the cervix) within the previous 3 years or at the same time.

• Known allergy to the study drug or any of its excipients;

• Active or uncontrolled severe infections;

2. A known history of clinically significant liver disease, including viral hepatitis [known hepatitis B virus (HBV) carriers must exclude active HBV infection, i.e., HBV DNA positivity (>1×104 copies /mL or >2000 IU/ mL);

3. Known hepatitis C virus infection (HCV) and HCV RNA positive (>1×103 copies /mL), or other hepatitis, liver cirrhosis];

• Any other disease, with clinical significance of metabolic abnormalities, abnormal physical examination or laboratory abnormalities, according to researchers, there is reason to suspect the patient has not suitable for the use of study drugs of a disease or condition (such as have a seizure and require treatment), or will affect the interpretation of results, or to make patients in high-risk situations;

• Other conditions deemed inappropriate for inclusion by the investigator.
