New combo therapy aims to shrink lung tumors before surgery

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Voluntarily participates in the study and provides written informed consent; 2. Aged 18-75 years, with no restriction on sex; 3. Histologically or cytologically confirmed diagnosis of non-small-cell lung cancer (NSCLC); 4. Has not received prior systemic therapy and is willing to undergo neoadjuvant treatment for stage cⅡ-Ⅲ (N2a) disease, according to the 9th edition of the AJCC staging system (Appendix 1); 5. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 (see Appendix 2 for scoring criteria); 6. Considered by the thoracic surgeon to have adequate pulmonary reserve to tolerate the planned lung resection; 7. Availability of tumor tissue prior to enrollment for pathological confirmation of EGFR/ALK wild-type status and PD-L1 expression assessment; 8. No significant hematologic, cardiac, pulmonary, hepatic, renal, or immunologic dysfunction, with the following laboratory parameters meeting the specified criteria: * Bone marrow function: absolute neutrophil count (ANC) ≥1.5×10⁹/L; platelet count ≥80×10⁹/L; hemoglobin ≥9 g/dL; * Liver function: total bilirubin ≤1.5× upper limit of normal (ULN); alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤1.5× ULN; * Renal function: serum creatinine ≤1.5× ULN or creatinine clearance ≥60 mL/min; blood urea nitrogen ≤200 mg/L; 9. Women of childbearing potential must have a negative serum pregnancy test within 3 days before the first dose of study treatment. Exclusion Criteria: * 1\. Presence of locally advanced unresectable or metastatic disease. Unresectable disease is defined according to the 2019 Multidisciplinary Consensus on Stage III Non-Small-Cell Lung Cancer (NSCLC), including certain stage IIIA and IIIB cases and all stage IIIC cases. Typically, this includes N2 disease with a single mediastinal lymph node ≥3 cm in short axis or multiple fused lymph nodes (≥2 cm in short axis on CT), as well as T4 lesions invading the esophagus, heart, aorta, or pulmonary veins, and all N3 disease. 2\. Superior sulcus (Pancoast) NSCLC, large-cell neuroendocrine carcinoma (LCNEC), or sarcomatoid carcinoma. 3\. Known EGFR-sensitive mutations or ALK rearrangements (non-squamous participants must have confirmed EGFR and ALK mutation status). 4\. Prior systemic anticancer therapy for early-stage NSCLC, including investigational agents. 5\. Active infection, or unexplained fever \>38.5 °C within 2 weeks prior to screening (participants with tumor-related fever, as judged by the investigator, may be enrolled). 6\. Male or female participants of reproductive potential who are unwilling to use effective contraception during the study; pregnant or breastfeeding women. 7\. Any condition that, in the opinion of the investigator, could interfere with study participation or completion, including severe comorbidities (including psychiatric disorders) requiring concurrent treatment, or family or social factors that may compromise participant safety or data integrity.
