Radiation therapy, also called radiotherapy, is one of the most common methods of treatment for cancer. More than 60 percent of cancer patients undergo radiotherapy at some point during their treatment. With surgery, radiotherapy is the standard of care for local cancer treatment.

Surgery plus radiotherapy improves the prognosis for many patients. However, while radiotherapy can be an effective treatment, the efficacy of treatment may be limited for some patients because the dose required to destroy the tumor may cause too much damage to surrounding healthy tissues.

To meet this unmet need, Nanobiotix is developing NBTXR3, a first-in-class radiohancer composed of hafnium oxide nanoparticles that is designed to destroy tumors when activated by radiotherapy. Clinical data have suggested that when NBTXR3 is activated, it increases the energy absorbed from radiotherapy up to nine times and enhances the dose delivered, inducing significant tumor cell death without increasing the damage to surrounding healthy tissue.

We believe that NBTXR3 activated by radiotherapy may become a new standard of care in the treatment of cancer, potentially helping millions of patients.
