7. Life expectancy ≥ 6 months
8. Laboratory results:
1. Adequate hematologic function, defined as absolute neutrophil count ≥1.5×10^9 /L,
platelet count ≥100 ×10^9 /L, hemoglobin ≥90g/L;
2. Adequate liver function, defined as total bilirubin levels ≤ 1.5 times normal
upper limit (ULN), and aspartate aminotransferase (AST) and alanine
aminotransferase (ALT) levels ≤ 2.5 times ULN, or AST and ALT levels ≤ 5 times
ULN for patients with hepatic metastasis;
3. Adequate renal function, defined as serum creatinine ≤ 1.5 times ULN or
creatinine clearance ≥ 50 ml / min (Cockcroft-Gault formula) and proteinuria <
2+;
4. Coagulation function is adequate, defined as international normalized ratio (INR)
or prothrombin time (PT) ≤ 1.5 times normal upper limit (ULN), PTT or aPTT ≤ 1.5
times ULN;
9. Expected protocol compliance
10. Patients of childbearing potential must agree to use effective contraceptive measures
during study treatment and for 6 months after receiving last study treatment (e.g.
abstinence, sterilization surgery, oral contraceptives, contraception by progesterone
injection or subcutaneous).
Exclusion Criteria:
1. Prior chemotherapy or target therapy with another systemic anti-cancer agent (e.g.,
monoclonal antibody, tyrosine kinase inhibitor) for the treatment of the patient's
current stage of disease (Stage IIIB not amenable for combined modality treatment,
stage IV or recurrent disease). Prior surgery and irradiation is permitted, provided
that the criteria outlined in the protocol for both treatments are met. Disease
progressed within 6 months after adjuvant therapy must be excluded.
2. Mixed non-small cell and small cell carcinoma, or mixed adenosquamous carcinomas with
predominant squamous cell
3. Histologically or cytologically confirmed EGFR sensitive mutation type, unknown EGFR
status for any reason is allowed in this study.
4. Known hemoptysis within 3 months prior to screening with blood volume more than 2.5 mL
each time
5. Evidence of tumor invading major blood vessels on imaging. The investigator or the
local radiologist must exclude evidence of tumor that is fully contiguous with,
surrounding, or extending into the lumen of a major blood vessel (e.g., pulmonary
artery or superior vena cava)
6. Evidence of brain metastasis, spinal cord compression or carcinomatous meningitis
history with clinical symptoms. For stable patients with no symptom, could be admitted
if fulfill all below criteria: measurable lesion(s) out of CNS, no metastasis at
mesocephalon, annular protuberance, medulla oblongata and spinal cord; no history of
intracranial bleeding.
7. Radical radiotherapy to the thorax with curative intent within 28 days prior to
enrollment; palliative radiotherapy for bone lesions outside the thoracic region
within 2 weeks prior to first dose of study treatment.
8. Serious, non-healing wound, active ulcer, or untreated bone fracture, or major
surgical procedure within 28 days prior to randomization or anticipation of need for
major surgery during the course of the study.
9. Minor surgery (Including insertion of an indwelling catheter) within 48 hours prior to
first dose of study treatment
10. Recent or current (within 10 days prior to first dose of study treatment) receive
treatment of Aspirin (> 325 mg/day) or other non-steroidal anti-inflammatory drugs
(NSAID) known to inhibit platelet function (within 10 days prior to first dose of
study treatment)
11. Recent or current receive treatment of oral all doses of oral or parenteral
anticoagulants or thrombolytic agent. Prophylactic use of anticoagulants is permitted.
12. History or evidence of inherited bleeding diathesis or coagulopathy or thrombus
13. Uncontrolled hypertension (SBP>140 mmHg and/or diastolic blood pressure>90 mmHg),
prior history of hypertensive crisis and hypertensive encephalopathy
14. Clinically significant cardiovascular disease but not limited to active infections;
unstable angina; stroke or transient cerebral ischemia (within 6 months prior to
screening); myocardial infarction (within 6 months prior to screening) ; congestive
heart-failure (New York Heart Association (NYHA) class≥ II) ; serious cardiac
arrhythmia, hepatic, renal or metabolic disease requiring medication during the study.
15. History of peptic ulcer, gastrointestinal perforation, erosive esophagitis, erosive
gastritis, inflammatory bowel disease or diverticulitis, abdominal fistula or
intra-abdominal abscess within 6 months prior to screening
16. Patient diagnosed with a tracheo-esophageal fistula
17. Clinically significant third space effusion (e.g., uncontrolled ascites or pleural
effusion by extraction or other treatment)
18. Pulmonary fibrosis or active pneumonia showed by CT at baseline
19. Active malignancy other than non-small cell lung cancer (NSCLC), treated carcinoma in
situ of the cervix, superficial basal cell or squamous cell carcinoma, radical surgery
of localized prostate cancer, radical surgery of ductal carcinoma in situ within 5
years prior to randomization
20. Known autoimmune disease
21. Known positive HbsAg and hepatitis B virus (HBV)-DNA drop test in peripheral blood ≥ 1
x 10^3 copy number/L or 200 IU/mL; If HBsAg positive and HBV-DNA drop test in
peripheral blood < 1 x 10^3 copy number/L or 200 IU/mL, patient is considered to be
eligible by investigator only when chronic hepatitis B in the plateau and do not
increase the risk
22. Known positive HIV or hepatitis C virus (HCV) or syphilis
23. Known allergic disease or allergic physique
