“Radiation is one of the most effective tools we have to treat cancer. The challenge is harnessing that power to target tumors more precisely without harming the patient and to make it more widely available. That’s what we're doing.”
18 million cancer patients are diagnosed each year worldwide, with the majority suffering from advanced metastatic disease. About 90% of patients living with metastatic cancer will die of it.

Our technology combines 211-Astatine, the most druggable alpha-emitting radioisotope, with multivalent single-domain antibodies to deliver potent alpha radiation that breaks DNA strands and kills the tumor cells while leaving normal cells unaffected.
