About half of all cancer patients will get radiation therapy (RT) as part of their treatment. But some cancers are naturally resistant to RT, and others become resistant over time. One idea to fight this resistance is to combine RT with treatments that boost the body’s immune response. In this project, we will test if a particular type of immunotherapy can overcome resistance to radiation and make RT work better. To check this idea, we’ll start by using lab mice to figure out the best way to do this treatment. These mouse tests will show us when to give the immunotherapy with RT for the best results. Once we know this, we’ll start a clinical trial with pet dogs that have cancer. The goals of this trial are to (1) prove that combining localized immunotherapy with standard RT is safe, and (2) show that this mix works better than just RT alone. The specific immunotherapy we’re looking at is called XCSgel-IL12. It’s a new type of treatment we made. It gets injected straight into the tumor, and it can be made in large amounts for a low cost. It looks very promising for beating radioresistance in many cancer types. This study will focus on soft tissue sarcoma. If it works well, we can start trials in humans with this type of cancer. It could also spark more research on combining RT with XCSgel-IL12 in other cancers in the future.
