ClinConnect Summary

This clinical trial is studying a new treatment approach for patients with locally advanced or metastatic squamous cell lung cancer, a type of lung cancer that can be difficult to treat. Researchers want to see if combining low-dose radiation and a specific type of radiation therapy called stereotactic body radiation therapy (SBRT) with a medication called sintilimab (which helps the immune system fight cancer) and standard chemotherapy is more effective than using sintilimab and chemotherapy alone. The trial will involve 114 participants, split evenly between the two treatment groups.

To be eligible for this trial, participants need to be between 18 and 75 years old and have been diagnosed with squamous cell lung cancer that cannot be removed with surgery. They should also have measurable disease confirmed by imaging tests and not have received any prior treatments for their cancer. Participants can expect to receive close monitoring and care throughout the trial, while contributing to the understanding of how these treatments work together. It's important to note that individuals with certain types of lung cancer or specific prior treatments will not be eligible to participate.
