application of pablizumab combined with apatinib and chemotherapy in resectable non-small cell lung cancer： a prospective, single arm, single center phase ii clinical study of neoadjuvant therapy

Conditions: Non-small Cell Lung Cancer

Summary: this is a prospective, single arm, single center clinical study to determine the efficacy and safety of pablizumab combined with apatinib and neoadjuvant chemotherapy in patients with stage iia-iiia non-small cell lung cancer. no egfr mutation or alk gene translocation was found in the untreated patients with nsclc stage iia-iiib diagnosed by imaging, histopathology or cytology. after informed consent is signed by the patients. the patients were treated according to the protocols. the patients were followed up from adjuvant treatment and follow-up to relapse free survival until disease progression, withdrawal of informed consent, loss of follow-up or death.

2. the tumor has invaded important blood vessels or the tumor is in the treatment stage according to the judgment of the researcher there is a high possibility of invading important blood vessels and causing massive hemorrhage; 3. known egfr mutation or alk gene translocation; 4. there are locally advanced unresectable diseases and metastatic diseases; 5. she had been suffering from the need to use corticosteroids (prednisolone) in 14 days before randomization daily dose of nisone or equivalent (10 mg) or other immunosuppressive drugs any disease requiring systemic treatment. local replacement steroids are permitted (daily dose ≤ 10 mg of prednisone or equivalent) and prescription corticosteroids short term (≤ 7 days) prophylactic use of alcohol or for the treatment of non autoimmune. any active autoimmune disease or history of autoimmunity; 6. active autoimmune diseases or autoimmune diseases that may recur history. admission of well controlled type i diabetes and hormone replacement therapy are allowed. hypothyroidism, well controlled celiac disease, and no need for complete treatment skin diseases (such as vitiligo, psoriasis or alopecia) treated by the body or not due to the absence of recurrence of the disease is not expected. 7. interstitial lung disease, non infectious pneumonia or poorly controlled diseases (including pulmonary fibrosis) history of vitamin c, acute lung disease, etc. 8. active hepatitis b (defined as screening hepatitis b virus surface antigen \[hbsag\]) the results were positive and hbv-dna was detected. the detection value was higher than that in the study upper limit of normal value of cardiology laboratory) or hepatitis c (defined as screening hepatitis c virus table) the subjects with positive results of hcsab and hcv-rna; 9. known human immunodeficiency virus (hiv) infection (known hiv antibody positive); 10. inoculate live vaccine within 30 days before the first administration. including but not limited to the following: mumps, rubella, measles, varicella / herpes zoster (varicella), yellow fever rabies, bcg and typhoid vaccine (inactivated virus vaccine allowed);

15. according to the judgment of the researcher, the subjects may confuse the test results and interfere it is not in the best interests of the subjects to participate in the whole trial a history or current evidence of any disease, treatment, or laboratory abnormality it's a good idea. 16. active bleeding. exclusion criterion: 1. ever received any treatment including chemotherapy or radiotherapy in the past; 2. the tumor has invaded important blood vessels. there is a high possibility of invading important blood vessels and causing massive hemorrhage if the tumor is in the treatment stage process according to the judgment of the researcher;
