Outline of Research at the Start

放射性同位元素(RI)を用いて診断治療を一体化して展開するラジオセラノスティクスは、個別化医療を実現している治療法であるが、診断・治療用RIの組み合わせは限定される。一方、核医学治療と他の局所治療法との併用はほとんど報告がないが、局所療法は相補的に機能すると考えた。そこで、本研究では、ラジオセラノスティクスを発展させるべく、通常の手法では組み合わせ不可能な核種を組み合わせたラジオセラノスティクス用プローブ開発を行い、次いで、局所療法とを組み合わせた新規プローブ開発を行い、有用性を評価する。

Outline of Final Research Achievements

In this study, we further advanced the concept of 'radio-theranostics,' which integrates diagnosis and therapy, and successfully developed novel hybrid agents combining the alpha-emitting radionuclide astatine-211 (At-211) with radiometals. The development of compounds for theranostics that combine anticancer drugs with nuclear medicine imaging, and the development of compounds for theranostics that combine nuclear medicine imaging with other local treatments, such as photodynamic therapy and BNCT were successfully achieved, and some good results were obtained.

Academic Significance and Societal Importance of the Research Achievements

本研究では、アルファ線放出核種であるAt-211と放射性金属を組み合わせたハイブリッド型の新規薬剤の開発に成功した。また、がん指向性Pt抗がん剤、PDT、BNCTと核医学イメージングを組み合わせたセラノスティクスへの応用展開により、がんの診断精度向上と治療効果の最大化を目指した新たな治療戦略を提案した点に独自性がある。これらの成果は、既存の治療法では効果が限定的であった難治性がんへの対応策として、個別化医療の実現を後押しするとともに、医療資源の効率的な活用を促進し、将来的な臨床応用に向けた技術的・実践的基盤の構築にも大きく貢献するものである。
