Summary

This trial is studying the effectiveness of radiation therapy combined with immunotherapy using the drug Avelumab to treat squamous cell carcinoma.

Who is the study for?
This trial is for adults with a type of skin cancer called unresectable cutaneous squamous cell carcinoma (cuSCC) that can't be removed by surgery. Participants must have measurable disease, be able to follow the study plan, and use effective birth control if they can have children. People with immune deficiencies, certain infections or recent vaccinations, severe allergies to monoclonal antibodies, or other serious health issues cannot join.
What is being tested?
The UNSCARRed Study is testing how well Avelumab combined with radiation therapy works against cuSCC. Patients will receive daily radiation treatments and Avelumab infusions every two weeks to see if this approach is more effective than previous treatments.
What are the potential side effects?
Possible side effects include typical reactions from immune therapies such as fatigue, infusion-related reactions like fever or chills, potential inflammation in various organs including the lungs (pneumonitis), and an increased risk of infection due to immune system activation.
