Measurable lesions based on the response evaluation criteria in solid tumors version 1.1; 5. Tumor tissue specimens available for pathological diagnosis, detection of PD-L1 expression and biomarkers prior to randomization (the tumor tissue specimens must be freshly obtained or archived samples within 3 months prior to enrollment; tumor tissue specimens must be the samples of histological category, including but not limited to the tissue punctured by core needle and hollow needle, tissue acquired by bronchoscopic clamp, surgically resected samples; the samples acquired by fine needle puncture and bronchial brushing are not acceptable); 6. ECOG score 0-1; 7. Good organ function: 8. Being willing and able to comply with the visits, treatment plan, laboratory examinations and other study procedures scheduled in the study; 9. pulmonary function test being able to withstand the planned pneumonectomy evaluated by surgeons; Women of childbearing potential must undergo serum pregnancy test within 3 hours prior to the first dose and the result must be negative. Female subjects of childbearing potential and male subjects whose partners are women of childbearing potential must agree to use highly effective contraceptive methods during the study period and within 180 days after the last dose of study drug. 10. Women of childbearing potential must undergo serum pregnancy test within 3 days prior to the first dose and the result must be negative. Female subjects of childbearing potential and male subjects whose partners are women of childbearing potential must agree to use highly effective contraceptive methods during the study period and within 180 days after the last dose of study drug
Exclusion Criteria
Exclusion criteria： 1. Presence of locally advanced, unresectable or metastatic disease; unresectable includes the unresectable defined in the Chinese expert consensus on the multidisciplinary diagnosis and treatment for stage III non-small cell lung cancer (2019), including partial stage IIIA and IIIB and all the stage IIIC; N2: single station mediastinal lymph node metastasis with short diameter ≥3cm; N2: multiple station mediastinal lymph node metastasis with lymph node fusion and the short diameter of lymph node ≥2cm on CT; ALL the N3; T4: invading esophagus, heart, aorta; 2. NSCLC involving superior sulcus, large cell neuroendocrine carcinoma (LCNEC), sarcomatoid tumor; 3. Participants with known EGFR sensitive mutations or ALK translocation, EGFR and ALK mutation status needs to be identified for the subjects with non-squamous cell carcinoma; 4. Previous treatment with systemic antitumor therapy for early NSCLC, including investigational product; 5. History of (non-infectious) pneumonitis/interstitial lung disease requiring steroid treatment, or ongoing pneumonitis/interstitial lung disease requiring steroid treatment; 6. Active tuberculosis; 7. Active infection requiring systemic treatment; 8. Subjects with any known or suspected autoimmune disorder or immunodeficiency, with the following exceptions: hypothyroidism, hormone therapy is not needed, or well controlled at physiological dose; controlled type I diabetes; 9. Uncontrolled active hepatitis B (defined as positive hepatitis B surface antigen [HBsAg] in screening period with HBV-DNA detected higher than the upper limit of normal at the clinical laboratory of the study center); (the subjects with HBV-DNA assay <500 IU/mL within 28 days prior to randomization who have received local standard antiviral therapy for at least 14 days and are willing to receive antiviral therapy continuously during the study can be enrolled); active hepatitis C (defined as positive hepatitis C surface antibody [HCsAb] in screening period and positive HCV-RNA); 10. Known human immunodeficiency virus (HIV) infection (known positive HIV antibody); 11. Vaccination of live vaccine within 30 days prior to the first dose. Including but not limited to the following: parotitis, rubella, measles, varicella/ herpes zoster (varicella), yellow fever, Rabies, Bacille Calmette-Guérin (BCG) and typhoid vaccine (inactivated virus vaccine allowed); 12. ≥ Grade 2 peripheral neuropathy; 13. Previous use of PD-1/PD-L1 agent or the drug acting on another targeted T cell receptor (e.g., CTLA-4, OX-40); 14. Severe allergic reaction to other monoclonal antibodies; 15. History of serious allergy to Pemetrexed, paclitaxel or docetaxel, cisplatin, carboplatin or its preventive medications; 16. Known serious or uncontrolled pre-existing diseases; including but not limited to cardiovascular events with hemodynamic instability, symptomatic cerebrovascular events, and hepatic cirrhosis above Child-Pugh A within 6 months; 17. History or current evidence of any disease, therapy or abnormal laboratory examination that may confuse the study results, interfere with subject's participation in the full course of the study or not meet the best interest of subject's participation in the study, as judged by investigators; 18. Other malignant tumors within 5 years prior to the first dose, except non-small cell lung cancer. The malignant tumors with negligible risk of metastasis or death (e.g., expected disease-free survival > 5 years) and expected to achieve radical outcomes after treatment (e.g., sufficiently treated carcinoma in situ of cervix, basal or squamous cell skin cancer, ductal carcinoma in situ treated for radical surgery) can be excluded.
