Inclusion Criteria:
1. The participants voluntarily signed the informed consent form.
2. The participants should be 18~75 years old.
3. Histology or cytology confirmed, stage IIIB to IV non-small cell lung cancer
(according to the eighth edition of the American Joint Committee on cancer AJCC
staging) that could not undergo radical treatment.
4. No sensitive EGFR mutation, ALK gene rearrangement and ROS1 gene rearrangement are
allowed.
5. Progressed after first-line treatment included immune checkpoint inhibitor (including
CTLA-4 monoclonal antibody, PD-1/L1 monoclonal antibody monothrapy or combination
therapy, with or without chemotherapy. If the first-line treatment is discontinued due
to adverse effects, and patients received no other treatment before disease
progression.
6. For patients who have previously received neoadjuvant and/or adjuvant immune
checkpoint inhibitor treatment (with or without chemotherapy or radiotherapy) for the
purpose of radical treatment of non-metastatic disease, if first-line treatment
contained immune checkpoint inhibitors (the same or different immune checkpoint
inhibitors with neoadjuvant or adjuvant settings), they can also be included.
7. At least one measurable lesion according to RECIST criteria v1.1. If patients received
radiotherapy, they can be included only when disease progression of the previously
irradiated lesion is observed, and the previously irradiated lesion is not the only
lesions.
8. ECOG PS score: 0-1.
9. The estimated survival time is more than 3 months.
10. Laboratory test results showed sufficient hematology and end organ functions.
11. Patients with asymptomatic central nervous system (CNS) metastases can be enrolled.
Patients with symptomatic CNS metastases should received local treatment and meet the
following conditions before enrollment: a) stable for at least 14 days before
enrollment with or without receiving steroids and anticonvulsant drugs; b) Complete
radiotherapy at least 14 days before enrollment; c) From the end of radiotherapy to
the screening phase, no CNS progression was found. If local CNS treatment is performed
before enrollment, there should be at least one extracranial measurable lesion
according to RECIST criteria v1.1.
12. Women of childbearing age should agree to use contraceptives (such as intrauterine
devices, contraceptives or condoms) during the study period and within 6 months after
the end of the study; Within 7 days before the study, the serum or urine pregnancy
test was negative; Non-lactating patients; Men should agree to use contraceptives
during the study period and within 6 months after the end of the study period.
13. Ability to follow research and follow-up procedures.
Exclusion Criteria:
1. Histologically mixed with small cell or squamous lung cancer.
2. Previously received anti-angiogenic drugs (including bevacizumab, arotinib, apatinib,
etc.) and/or paclitaxel (including paclitaxel, paclitaxel liposomes, and
nab-paclitaxel). If paclitaxel is used in the adjuvant treatment setting, patients who
progressed after 6 months from the last dose of paclitaxel can be included.
3. Patients diagnosed with secondary primary malignant tumor within 5 years before
enrollment, except cured cervical carcinoma in situ, superficial bladder tumor [Ta,
Tis and T1], basal or squamous cell skin cancer, localized prostate cancer after
radical surgery and breast ductal carcinoma in situ after radical surgery.
4. Patients with leptomeningeal metastasis or untreated symptomatic or rapidly
progressing CNS metastasis.
5. Unrelieved toxic reactions of CTCAE (5.0) grade 2 or higher caused by any previous
treatments, excluding hair loss, nausea and vomiting.
6. For uncontrollable tumor-related pain, patients who need analgesic treatment must have
a stable analgesic treatment plan at enrollment. If there are symptomatic lesions
suitable for palliative radiotherapy (such as bone metastasis or metastatic nerve
invasion), the treatment should be completed before enrollment. The patient should
recover from the effects of radiation. For asymptomatic metastatic lesions, if the
investigator believes there is the possibility of dysfunction or intractable pain
(such as epidural metastasis not currently related to spinal cord compression), local
regional treatment should be considered before enrollment.
7. Major surgery other than that for the purpose of diagnosis was performed within 4
weeks before enrollment, or expected major surgery during the study period.
8. Serious infection within 4 weeks before enrollment, including but not limited to
infection, bacteremia or severe pneumonia that leads to hospitalization, or any active
infection that the investigator believes may affect the safety of patients.
9. Patients with any severe and / or uncontrolled disease, including:
(1) Patients with unsatisfactory blood pressure control (systolic blood pressure > 150 mmHg
or diastolic blood pressure > 90 mmHg), hypertensive crisis or hypertensive encephalopathy;
(2) Major cardiovascular diseases, including but not limited to: myocardial ischemia or
myocardial infarction above grade I, arrhythmia (including QTc = 440ms) and congestive
heart failure = grade 2 (NYHA classification); (3) Active or uncontrolled severe infection
(= CTCAE grade 2 infection); (4) Have a history of immunodeficiency, including HIV positive
or other acquired or congenital immunodeficiency diseases, or have a history of organ
transplantation; (5) Uncontrolled pleural effusion, pericardial effusion and peritoneal
effusion requiring repeated drainage (once a month or more frequently); (6) Poor control of
diabetes [fasting blood glucose (FBG) > 10mmol/l]; (7) Urine routine examination showed
that urine protein was =++, and the 24-hour urine protein was confirmed to be more than 1.0
G; (8) Patients who have seizures and need treatment; (9) Uncontrolled or symptomatic
hypercalcemia (ionic calcium > 1.5 mmol/l, calcium > 12 mg/dl or corrected serum calcium >
ULN).
10. Arteriovenous thrombosis events, such as cerebrovascular accident (including transient
ischemic attack), deep venous thrombosis and pulmonary embolism within 6 months before
enrollment.
11. Hemoptysis = grade 2 (defined as = 2.5 ml of bright red blood each time) within 3
months before enrollment.
12. Bleeding tendencies or coagulation disorders (i.e. without the use of therapeutic
anticoagulants).
13. Tumor infiltration or adjacency to large blood vessels. 14. A history of abdominal
fistula, gastrointestinal (GI) perforation, abdominal abscess, or active gastrointestinal
bleeding within 6 months before enrollment.
15. Aspirin (> 325 mg/d) or clopidogrel (> 75 mg/d) was used currently or recently (10 days
before starting the study treatment). The preventive use of anticoagulants is permitted.
16. Active pulmonary tuberculosis (TB) or subjects with a history of active TB infection
within = 48 weeks before enrollment, whether treated or not.
17. Have a history of idiopathic pulmonary fibrosis, organized pneumonia (such as
bronchiolitis obliterans), drug-induced pneumonia, radiation pneumonia requiring steroid
treatment or active pneumonia with clinical symptoms; Or other moderate or severe lung
diseases that seriously affect lung function.
18. Has a history of psychotropic substance abuse and is unable to quit or has mental
disorders.
19. Known history of allergic or hypersensitive to any component of carboplatin / cisplatin

20. Pregnant or lactating women. 21. According to the judgment of the investigator, there
are concomitant diseases that seriously endanger the safety of the patient or affect the
completion of the study.
