NBTXR3, Radiation, and Immunotherapy for Advanced Solid Tumors

This study is looking at how safe and effective a combination treatment is for advanced solid tumors that have spread to the lung or liver. The treatment involves NBTXR3 (Hafnium Oxide-containing Nanoparticles) given directly into the tumor, along with radiation therapy and immunotherapy (Anti-PD-1/L-1, like nivolumab). NBTXR3 may help make tumor cells more sensitive to radiation, while immunotherapy aims to help your body's immune system fight the cancer. The study will measure side effects and how many patients respond to the treatment. You may be able to join if you have metastatic disease in the lung and/or liver, or soft tissue, from any primary cancer that cannot be cured by local treatments. You may have also received one prior anti-PD-1/L1 therapy. The study is currently enrolling about 40 participants.

Study design
This is a Phase I/II interventional study that will enroll about 40 participants. Participants will be randomly assigned to one of two groups to receive different types of radiation therapy.
What's involved
You would receive NBTXR3 directly into your tumor, followed by Anti-PD-1/L-1 intravenously, and then radiation therapy over 1-2 weeks. Immunotherapy cycles may repeat every 3-6 weeks for up to 2 years.
Compensation
Not stated in the trial record.
Follow-up
The study will track side effects for up to 4 weeks after radiation therapy and measure how well the treatment works for up to 12 weeks after radiation therapy.
