Eligibility Criteria

Inclusion Criteria

1. Sign a written Informed Consent Form (ICF) and be able to comply with the visit and related procedures specified in the protocol.

2. Age ≥ 18 years old.

3. Primary non-small cell lung cancer (including adenocarcinoma and squamous cell carcinoma) diagnosed by cytology or histology.

4. According to the International Association for the Study of Lung Cancer and the Joint Committee on Cancer Classification 8th edition (AJCC8) TNM staging classification of lung cancer, the clinical staging is IIB (primary tumor>4cm), IIIA, or IIIB (resectable N2 only) stage. Resectable N2 refers to non bulk (defined as a short diameter less than 3cm), discrete, or single site N2 involvement. If clinically suspected as N2 or N3, pathological confirmation is required.

5. Non squamous NSCLC subjects need to undergo genetic testing to confirm the absence of EGFR sensitive mutations and ALK rearrangements. Squamous NSCLC subjects are not required to undergo genetic testing, but subjects with known EGFR sensitive mutations and ALK rearrangements should not be included in the study.

6. Considered suitable for radical resection surgery.

7. The lung function meets the criteria for planned lung resection (FEV1 ≥ 50% predicted value, MVV ≥ 50% predicted value), and there are no surgical contraindications.

8. Can provide sufficient tissue specimens that meet the requirements for PD-L1 testing during the screening period.

According to RECIST V1.1, there is at least one measurable lesion. 10. The Eastern Cooperative Oncology Group Performance Status (ECOG PS) score is 0 or 1.

11. Have not received any systemic anti-tumor therapy or local radiotherapy for NSCLC in the past.

12. Possess sufficient organ and bone marrow function, with laboratory test values meeting the following requirements within 7 days prior to enrollment (no blood components, cell growth factors, albumin, or other intravenous or subcutaneous drugs for correcting hematological or liver and kidney dysfunction are allowed within 14 days prior to obtaining laboratory tests), as follows: Hematological function is sufficient, defined as absolute neutrophil count ≥ 1.5 × 109/L, platelet count ≥ 100 × 109/L, hemoglobin ≥ 100g/L;

• Adequate liver function, defined as total bilirubin levels ≤ 1.5 × upper limit of normal (ULN) and levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × ULN, albumin (ALB) ≥ 35g/L;
• Adequate renal function, serum creatinine (Scr) ≤ 1.5 × ULN, creatinine clearance rate (CrCl) ≥ 60mL/min (calculated using the Cockcroft/Gault formula), and urine routine test results showing urinary protein (UPRO)<2+or 24-hour urine protein dose<1g; Within 7 days prior to treatment, the international normalized ratio (INR) is ≤ 1.5 × ULN, and the prothrombin time (PT) or activated partial thromboplastin time (APTT) is ≤ 1.5 × ULN.

13. For female subjects of childbearing age, urine or serum pregnancy tests were negative within 7 days prior to receiving the first study drug administration. 14.If the urine pregnancy test result is positive, a blood pregnancy test is required.

15.If there is a risk of conception, male and female patients should use highly effective contraception (i.e. methods with an annual failure rate of less than 1%) and continue for at least 180 days after stopping the trial treatment. Note: If abstinence is the subject's usual lifestyle and preferred contraceptive method, then abstinence is acceptable as a contraceptive method.

HBsAg (+) subjects should receive anti HBV therapy throughout the entire study drug treatment period to avoid viral activation.

For subjects with anti HBc (+), HBsAg (-), anti HBs (-), and HBV viral load (-), prophylactic anti HBV treatment is not necessary, but close monitoring of virus reactivation is necessary.

26. Active hepatitis C (HCV antibody positive and HCV-RNA level above the detection limit).

27. Malignant tumors other than diagnosed NSCLC within the first 5 years of randomization, excluding fully treated cervical carcinoma in situ, basal cell or squamous cell carcinoma of the skin, local prostate cancer after radical surgery, ductal carcinoma in situ after radical surgery, and papillary thyroid carcinoma after radical surgery.

28. It is known that there is an allergic reaction to the active ingredients and/or any excipients of the selected chemotherapy regimen (non squamous NSCLC: pemetrexed plus cisplatin or carboplatin; squamous NSCLC: gemcitabine, docetaxel, paclitaxel or albumin paclitaxel plus cisplatin or carboplatin).

29. Pregnant or lactating women or women preparing to become pregnant or breastfeed during the study period.

30. It is known that there are mental illnesses or drug abuse situations that may affect compliance with experimental requirements, and there is a history of alcohol abuse.

31. There may be medical history, diseases, treatments, or laboratory abnormalities that could interfere with the trial results, hinder the full participation of the subjects in the study, or the researcher believes that participating in the study is not in the best interests of the subjects. Local or systemic diseases caused by non malignant tumors, or secondary reactions to cancer, can lead to higher medical risks and/or uncertainty in survival evaluation.
