Clinical Trial Summary

The purpose of this study is to evaluate the efficacy and safety of QL1706 combined with platinum-based chemotherapy versus placebo combined with platinum-based chemotherapy in adjuvant treatment of stage II-IIIB NSCLC without EGFR-sensitizing mutations and ALK fusions after complete surgical resection.The subjects were randomly divided into two groups according to 1:1, with about 316 subjects in the experimental group and the control group.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Disease-free Survival (DFS) in the PD-L1 =1% Population, Assessed by Investigator.	DFS was defined as the time from randomization to first recurrence of NSCLC, appearance of new primary NSCLC, or death from any cause, whichever occurred first. Tumor recurrence includes local recurrence and distant metastasis.	Up to approximately 84 months
Primary	Disease-free Survival (DFS) in the ITT Population, Assessed by Investigator.		Up to approximately 84 months
Secondary	Overall Survival (OS)	OS is defined as the time from random to death from any cause. OS will be measured in the PD-L1 subpopulation and in the ITT population.	Up to approximately 108 months
Secondary	Percentage of Participants Who are Survival at Year 4	OS rates will be measured in the PD-L1 subpopulation and in the ITT population.	Year 4
Secondary	Percentage of Participants Who are Disease-Free at Year 3	DFS rates will be measured in the PD-L1 subpopulation and in the ITT population.	Year 3
Secondary	Percentage of Participants Who are Disease-Free at Year 5	DFS rates will be measured in the PD-L1 subpopulation and in the ITT population.	Year 5
Secondary	DFS Within Selected Populations	Assessed by Investigator	Up to approximately 108 months
Secondary	Percentage of Participants with Adverse Events and Serious Adverse Events		Up to approximately 108 months
