This study is for people aged 60 and older with head and neck cancer (HNSCC) who can't use platinum-based chemo. The study looks at a new treatment, JNJ-90301900 (NBTXR3), combined with radiation therapy (RT) and possibly cetuximab, compared to just RT and possibly cetuximab. **JNJ-90301900** is injected directly into the tumor and then activated by RT. **Cetuximab** is a drug that helps RT work better against cancer cells.
People joining the study will have a check-up before starting to see if they can participate. If eligible, they will be randomly assigned to one of the two groups: one group will receive JNJ-90301900 with RT, and the other just RT. Both groups will have RT for 7 weeks. After treatment, check-ups will occur every 12 weeks for 2 years, then every 24 weeks.
Key Points:
- Participation lasts for a minimum of 2 years with regular follow-up visits.
- This study involves new treatment methods that could improve outcomes for older patients.
- Participants must meet specific health criteria and cannot have certain other cancers or infections.
