Targeted Radionuclide Therapy

  • Targeted radionuclide therapy (TRT) is an evolving class of precision therapy for various tumors, whereby highly specific targeting moieties facilitate the delivery of a radioactive payload1,2

  • Bayer’s TRT portfolio includes novel targeting approaches combining alpha radionuclides with antibodies, small molecules, and peptide-based molecules. We are exploring targeted alpha therapy (TAT) for a range of solid tumors3-7

  • Alpha emitters deliver highly ionizing radiation to tumor cells and the tumor microenvironment, inducing DNA damage, cell cycle arrest, and cell death8-10

    • Properties of alpha particles include high linear energy transfer with short-range penetration, leading to anti-tumor activity while limiting exposure to surrounding normal tissue8,9

    • Compounds currently under development utilize actinium-225, an alpha particle–emitting radionuclide with a 10-day half-life10


The ongoing clinical trials listed on this website represent a comprehensive overview of Bayer's clinical pipeline in Oncology, including Bayer-sponsored research and collaborative research with academic centers, cooperative groups, and other global institutions.
