Summary

This trial is testing if cemiplimab monotherapy is better than cemiplimab in combination with RP1 for patients with locally advanced or metastatic CSCC.

Who is the study for?
This trial is for adults with advanced squamous skin cancer who can't have or don't want surgery/radiotherapy. They should be relatively active (ECOG ≤1), expected to live more than 12 weeks, and able to provide a tumor sample. Not allowed if they've had certain previous treatments, active brain metastases, lung inflammation in the last 5 years, recent vaccines, herpes complications, need anti-herpetic drugs regularly, significant autoimmune disease treated with immunosuppressants within 5 years, or have hepatitis B/C or HIV.
What is being tested?
The study compares two approaches: Cemiplimab alone versus combined with RP1 in patients with locally advanced or metastatic cutaneous squamous cell carcinoma (CSCC). The main focus is on how well these treatments shrink tumors according to independent reviews.
What are the potential side effects?
Possible side effects include immune-related reactions that could affect various organs like the lungs and liver; infusion reactions; fatigue; skin issues; potential worsening of infections including herpes due to immune system changes.
