Inclusion Criteria: 1. Able to fully understand and voluntarily sign the informed consent form, and willing and able to comply with the clinical study procedures and follow-up visits. 2. Aged 18 to 75 years old (inclusive of both upper and lower limits), male and female subjects are eligible. 3. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) score of 0-1. 4. Expected survival ≥ 12 weeks. 5. Histologically or cytologically confirmed locally advanced (Stage IIIB/IIIC) or metastatic (Stage IV) non-squamous non-small cell lung cancer (NSCLC) (confirmed per the 9th Edition of the TNM Staging System for Lung Cancer by the Union for International Cancer Control \[UICC\] and the American Joint Committee on Cancer \[AJCC\]), which is inoperable for radical resection and ineligible for radical concurrent/sequential chemoradiotherapy as well as immunotherapy as consolidation treatment. Note: For subjects with locally advanced (Stage IIIB/IIIC) non-squamous NSCLC who are inoperable for radical resection and ineligible for radical concurrent/sequential chemoradiotherapy as well as immunotherapy as consolidation treatment, assessment by relevant specialist physicians and provision of written documentation are required for confirmation. 6. No prior systemic antineoplastic treatment for the study disease (including systemic chemotherapy, targeted therapy, and immunotherapy). Note: Subjects who previously received neoadjuvant, adjuvant, or radical concurrent/sequential chemoradiotherapy for non-metastatic disease with curative intent are eligible if disease progression occurs \> 180 days after the last dose of prior treatment. 7. Subjects must provide tumor tissue samples (archived or freshly obtained) collected at or after the diagnosis of locally advanced or metastatic tumor for central laboratory testing of PD-L1 expression. Note: The following samples are not accepted: fine-needle aspiration samples (without intact tissue structure, only cell suspensions or smears), brush cytology samples, cell smears from centrifuged pleural effusion drainage, bronchoalveolar lavage fluid samples, and bone lesions without soft tissue components or decalcified bone tumor samples. Tumor lesions used for fresh tissue biopsy should not be designated as RECIST v1.1 target lesions, unless the lesion is the only measurable lesion. For archived samples, they must be collected after the last systemic treatment, and the collection site must not have received radiotherapy. If a subject's archived samples do not meet the above requirements and the investigator judges that a biopsy is not in the subject's best interest, the use of archived samples may be permitted after discussion with the sponsor. 8. No sensitive EGFR mutations or ALK gene rearrangements. Prior tissue-based test reports for EGFR and ALK status must be provided. If the test reports do not meet the study requirements or are unavailable, tumor tissue samples must be provided for assessment of EGFR and ALK status (tested by a local laboratory recognized by the study site or the central laboratory) before enrollment. Note: For subjects with squamous NSCLC (excluding mixed-type NSCLC, e.g., adenosquamous carcinoma) who have a smoking history or are current smokers, if the prior EGFR and ALK status is unknown, testing for these markers is not required before enrollment, and they will be deemed negative. 9. Per RECIST v1.1 criteria (see Appendix 2), the subject must have at least one measurable (non-brain metastatic) lesion suitable for repeated and accurate measurement. Tumor lesions previously treated with radiotherapy or other local therapies must not be designated as target lesions, unless: The lesion is the only measurable lesion, and the investigator can provide imaging evidence (both pre- and post-local treatment) confirming clear disease progression of the lesion following local therapy; The lesion used for fresh tissue biopsy must not be designated as a target lesion, unless it is the only measurable lesion and the biopsy date is more than 4 weeks prior to the first dose of study treatment. 10. Confirmed adequate organ function, with mandatory compliance with the following laboratory parameters: Hematology (no receipt of any blood component transfusion or hematopoietic growth factor support therapy within 14 days prior to screening tests): 1.

Urine protein \< 2+; if urine protein ≥ 2+, 24-hour urine protein excretion must be \< 1 g; Hepatic function: 1. Serum Total Bilirubin (TBiL) ≤ 1.5 × ULN; for subjects with liver metastasis or confirmed Gilbert's syndrome, TBiL ≤ 3 × ULN; 2. Serum Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT) ≤ 2.5 × ULN; for subjects with liver metastasis, ALT and AST ≤ 5 × ULN; 3. Serum Albumin (ALB) ≥ 30 g/L; Coagulation function: Activated Partial Thromboplastin Time (APTT) and International Normalized Ratio (INR) ≤ 1.5 × ULN (for subjects receiving anticoagulant therapy, the investigator must confirm that both INR and APTT are within the safe and effective therapeutic range); Cardiac function: Left Ventricular Ejection Fraction (LVEF) ≥ 50%. 11. Female and male subjects of childbearing potential must agree to use effective contraceptive measures from the screening period until 90 days after the last dose of study treatment. Discussion with the investigator is required to determine whether contraception can be discontinued after this period. Female subjects must not be breastfeeding. Female subjects of childbearing potential must have a negative serum pregnancy test result within 7 days before randomization. Exclusion Criteria: 1. Histologically confirmed presence of any small cell carcinoma, neuroendocrine carcinoma, or sarcoma components \[mixed-type NSCLC (e.g., adenosquamous carcinoma) is permitted for enrollment\]. 2. Known presence of driver gene alterations with approved first-line therapeutic options, such as sensitive EGFR mutations, ALK fusion, ROS1 fusion, BRAF V600 mutation, NTRK fusion, MET exon 14 skipping mutation, or RET fusion. 3.

Symptomatic central nervous system (CNS) metastasis. For subjects with asymptomatic CNS metastasis or those with symptomatically stable CNS metastasis for ≥ 4 weeks prior to randomization, enrollment is permitted only if all the following criteria are met: * No metastasis to the meninges, midbrain, pons, medulla oblongata, spinal cord, or spinal cord compression; ② No increase in lesion size or new lesions after treatment; * No history of intracranial hemorrhage; * Discontinuation of corticosteroid therapy for ≥ 2 weeks prior to randomization; ⑤ No significant perilesional edema surrounding brain metastases; ⑥ The longest diameter of brain metastases ≤ 1.5 cm. 5.

Additionally, for subjects who previously received PD-(L)1 inhibitors in the neoadjuvant/adjuvant setting or as consolidation therapy after definitive chemoradiotherapy, enrollment may be permitted (with sponsor approval) if the interval between the end of the last treatment and the occurrence of disease progression is more than 12 months. Note: For subjects with prior PD-(L)1 inhibitor exposure: Enrollment is prohibited if the subject experienced ≥ Grade 3 immune-related adverse events (irAEs) caused by prior immunotherapy (excluding endocrine-related irAEs), irAEs leading to permanent treatment discontinuation, ≥ Grade 2 immune-related cardiotoxicity, or immune-related neurological or ophthalmic irAEs of any grade; Screening is prohibited if all adverse events caused by prior immunotherapy have not been fully resolved or resolved to Grade 1 before study screening.
