• Status: Recruiting
• Trial end date: 2027-02-28
• Target enrollment: 0
• Participant gender: All

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.
