Development of a [177Lu]BPAMD Labeling Kit and an Automated Synthesis Module for Routine Bone Targeted Endoradiotherapy

Painful bone lesions, both benign and metastatic, are often managed using conventional analgesics. However, the treatment response is not immediate and is often associated with side-effects. Radionuclide therapy is used for pain palliation in bone metastases as well as some benign neoplasms. Endoradiotherapy has direct impact on the pain-producing bone elements, and hence, response is significant, with minimal or no side-effects. A new potential compound for endoradiotherapy is [(177)Lu]BPAMD. It combines a highly affine bisphosphonate, covalently bridged with DOTA through an amide bond, with the low-energy β(-) emitting therapeutic radiolanthanide (177)Lu. For routine chemical application,…
