Outline of Final Research Achievements

Targeted radionuclide therapy using α particle emitters is a promising anticancer therapy. We established a reliable method for the production of At-211, an α particle emitter that is a promising radionuclide for targeted radionuclide cancer therapy. We further demonstrated that At-211-labeled anti-HER2 antibody showed an effective killing of HER2-positive gastric cancer cells and tumor suppression in a xenograft mouse model. These data suggest that radioimmunotherapy using At-211 is a promising anticancer therapy to HER2-overexpressing tumors.
