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
Trial Parameters
Brief Summary
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.
Eligibility Criteria
Inclusion Criteria: 1. Age≥ 18 years old; 2. Patients with histologically or cytologically confirmed non-bone metastases stage IV NSCLC; 3. EGFR, ALK, and ROS1 are all wild-type (for other driver genes, if there is no first-line approval for corresponding targeted therapy or if the patient refuses targeted therapy, these patients are allowed to be enrolled); 4. first-line treatment with immune checkpoint inhibitors and clinical benefit (PFS ≥ 3 months); 5. Have measurable lesions (according to RECIST 1.1 criteria, the long diameter of CT scan of tumor lesions is ≥10mm, the short diameter of CT scan of lymph node lesions is ≥15mm, and the thickness of the scanning layer is not more than 5mm, and the measurable lesions have not received local treatment such as radiotherapy and cryotherapy); 6. ECOG PS: 0-2 points; 7. Estimated survival time≥ 3 months; 8. Adequate hematologic function, defined as absolute neutrophil count ≥1.5×109/L, platelet count ≥ 80×109/L, hemoglobin ≥ 90g/L (no histo
