Next-Generation Radionuclide for Precision Oncology

Non-Carrier added (NCA) lanthanide Terbium-161(Tb-161) is is produced by neutron activation of Gadolinium-160 and offers a unique decay profile, setting new standards for targeted radioligand therapy (RLT).

Radioligand Therapy

Using PSMA and SST analogues, Terbium-161 has shown excellent bioequivalence presenting a biodistribution comparable to the currently used radiolanthanides. Additionally, the 16-fold increase in Auger and conversion electrons is expected to improve the cellular absorbed dose up to 3-fold compared to currently used radiolanthanides, while allowing for treatment of both primary and undetectable (micro) metastasis, improving the overall disease control. 

Imaging Optimized

Allowing optimization of the SPECT reconstruction parameters, Terbium-161 may provide for higher spatial resolution SPECT imaging, leading to the detection of smaller lesions that provides input for a further optimized treatment plan.

Radiation Safety

Terbium-161 provides for an immediate decrease in dose rate allowing for a significant improvement in general radiation safety. This optimization of radiation safety may extend current treatment room capacity for Radioligand Therapy. The non-carrier added (NCA) product allows optimal control of radioactive waste flow with reduced decay time in local storage.
