This study is a randomized, controlled, double-blind, multicenter Phase III registration clinical trial, aiming to evaluate the efficacy and safety of HB0025 combined with chemotherapy (pemetrexed plus carboplatin/cisplatin) versus tislelizumab combined with chemotherapy (pemetrexed plus carboplatin/cisplatin) as a first-line treatment for unresectable locally advanced (Stage IIIB/IIIC) or metastatic (Stage IV) nonsquamous non-small cell lung cancer (NSCLC).
The study will take progression-free survival (PFS) assessed by Blinded Independent Central Review (BICR) as the primary endpoint, and plans to enroll approximately 500 subjects. After being eligible for screening, patients will be randomly assigned to the study groups at a ratio of 1:1 to receive either HB0025 combined with chemotherapy (experimental group) or tislelizumab combined with chemotherapy (control group). Both regimens will be administered once every 3 weeks (Q3W). After completing 4 cycles of treatment, patients will enter the maintenance therapy phase with HB0025 or tislelizumab plus pemetrexed (Q3W). The treatment will last until the investigator determines that there is no longer clinical benefit (based on comprehensive assessment of RECIST v1.1 imaging results and clinical symptoms), intolerable toxicity occurs, 35 cycles of study treatment are completed, or other treatment termination criteria specified in the protocol are met, whichever comes first.
