Spots Global Cancer Trial Database for Phase II Trial: Low-Dose Radiation + SBRT + Sintilimab + Chemotherapy vs. Sintilimab + Chemotherapy in Advanced Squamous Cell Lung Cancer

Study Description

Brief Summary: This is a randomized, controlled, open-label, multicenter phase II clinical trial comparing the efficacy and safety of low-dose radiation therapy and stereotactic body radiation therapy combined with PD-1 inhibitor (sintilimab) and standard platinum-based doublet chemotherapy versus PD-1 inhibitor (sintilimab) combined with standard platinum-based doublet chemotherapy as first-line treatment in patients with advanced squamous cell lung cancer. There will be 57 subjects in the experimental group and 57 subjects in the control group, with a total of 114 subjects.

Detailed Description: This is a randomized, controlled, open-label, multicenter phase II clinical trial comparing the efficacy and safety of low-dose radiation therapy and stereotactic body radiation therapy combined with PD-1 inhibitor (sintilimab) and standard platinum-based doublet chemotherapy versus PD-1 inhibitor (sintilimab) combined with standard platinum-based doublet chemotherapy as first-line treatment in patients with advanced squamous cell lung cancer. Patients with previously untreated, advanced or metastatic (stage IV) squamous cell lung cancer who have signed informed consent will be screened for eligibility. Qualified subjects who meet the inclusion criteria will be randomly assigned at a 1:1 ratio to the experimental group (radiation therapy plus sintilimab and chemotherapy) or the control group (sintilimab plus chemotherapy). Based on sample size estimation according to statistical hypotheses, there will be 57 subjects in the experimental group and 57 subjects in the control group, with a total of 114 subjects. Subjects in the experimental group will receive radiation therapy. Within 1 week after radiation therapy, they will receive treatment with sintilimab combined with standard platinum-based doublet chemotherapy. Chemotherapy combined with immunotherapy will consist of a total of 4 cycles. Patients will subsequently receive maintenance therapy with sintilimab. Subjects in the control group will receive treatment with sintilimab combined with standard platinum-based doublet chemotherapy, consisting of a total of 4 cycles. Patients will subsequently receive maintenance therapy with sintilimab. The primary efficacy endpoint of this study is objective response rate (ORR), as assessed by investigators according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1).
