An Exploratory Study of Tislelizumab in Combination with Chemotherapy in Immuno-experienced Patients with EGFR/ALK/ROS1-negative Advanced NSCLC in the Second-line Setting

The goal of this clinical trial is to explore the efficacy and safety of denosumab in combination with tislelizumab and chemotherapy in the second-line treatment of immuno-experienced patients with EGFR/ALK/ROS1-negative advanced NSCLC. Primary endpoint: progression-free survival (PFS) assessed by investigators according to RECIST 1.1; Secondary endpoint: 1. Overall survival (OS) assessed by investigators according to RECIST 1.1; 2. Objective response rate (ORR) assessed by investigators according to RECIST 1.1; 3. Disease control rate (DCR) assessed by investigators according to RECIST 1.1; 4. Duration of response (DOR) assessed by investigators according to RECIST 1.1; Exploratory endpoint: bone metastasis-free survival. Participants will receive denosumab combined with tislelizumab and docetaxel.
