RAD-VACCINE Trial Summary

This trial is testing a new way to treat bladder cancer by combining an immunotherapy drug with radiation.

Who is the study for?
This trial is for adults with muscle-invasive bladder cancer who can't have cisplatin chemotherapy. They need good bone marrow and kidney function, no severe infections or heart issues recently, and no history of certain autoimmune diseases or other cancers in the last 2 years. Participants must be willing to use effective contraception.Check my eligibility
What is being tested?
The study tests Sasanlimab (an immune checkpoint inhibitor) combined with stereotactic body radiation therapy before surgery for bladder cancer. It's a phase II trial where all participants receive this combination as a potential 'in-situ vaccine' to boost their immune response against the cancer.See study design
What are the potential side effects?
Sasanlimab may cause immune-related side effects like inflammation in various organs, skin reactions, hormone gland problems, and infusion reactions. Radiation therapy might lead to localized skin irritation, fatigue, and discomfort.
