4. objective imaging progression (RECIST v1.1 assessment) after subjects have received a first-line regimen containing immune checkpoint inhibitor therapy.

5. the immune checkpoint inhibitor-containing therapy PFS of ≥ 6 months on first- line therapy.

6. imaging evaluation (CT or MRI) with at least one measurable target lesion (according to RECIST v1.1) within 4 weeks prior to enrollment.

7. an ECOG PS score of 0-1 within 4 weeks prior to enrollment.

8. an expected survival of ≥ 12 weeks.

9. Adequate function of vital organs

10. Non-surgical sterilization or female patients of childbearing age must have a negative serum pregnancy test within 7 days prior to the first dose and must be non-lactating. Female patients of childbearing age or male patients whose partners are women of childbearing age must agree to use highly effective methods of contraception during the study period and for 6 months after the last administration of the study drug.

Exclusion Criteria:

1. patients with other pathological tissue types of non-small cell lung cancer (including squamous cell carcinoma, mixed non-small cell and small cell lung cancer, and predominantly squamous adenosquamous carcinoma of the lung)

2. patients with known EGFR-sensitive mutations (19Exon del/21Exon L858R), positive ALK/ROS1 fusion.

3. patients with imaging showing signs of tumor invasion into the great vessels, where the tumor has completely approached, encircled, or invaded the lumen of a great vessel (e.g., pulmonary artery or superior vena cava)

4. patients with hypertension whose blood pressure is not satisfactorily controlled by antihypertensive medication (sitting systolic blood pressure > 150 mmHg, or diastolic blood pressure > 100 mmHg), previous hypertensive crisis or hypertensive encephalopathy.

5. those with a known hereditary bleeding tendency or coagulation disorders; those who have received full-dose anticoagulant or thrombolytic therapy within 10 days prior to enrollment, or those who have taken non-steroidal anti-inflammatory drugs with platelet inhibitory effects within 10 days prior to enrollment (except for prophylactic use of low-dose aspirin (≤325 mg/day)).

6. had a hemoptysis of 2nd degree or greater with a single hemoptysis of ≥1/2 teaspoon (2.5 ml) within 3 months prior to enrollment thrombosis in the 6 months

7. prior to enrollment and an arterial/venous thrombotic event within 1 year prior to screening, such as cerebrovascular accident (including transient ischemic attack), deep vein thrombosis, and pulmonary embolism.

8. those with severe vascular lesions (including aneurysms or arterial thrombosis requiring surgical treatment) within 6 months prior to enrollment

9. late first-line treatment with anti-angiogenic agents, including but not limited to bevacizumab, apatinib, anlotinib, ramucirumab, lenvatinib, etc.; treatment with docetaxel.
