A 177Lu-Labeled Circular Bivalent Aptamer for PTK7-Targeting Radionuclide Therapy in Ovarian Cancer and Orthotopic Hepatoblastoma.
Targeted radionuclide therapy (TRT) is a promising strategy for precision oncology but is limited by the lack of high-performance targeting ligands. Here, we report a lutetium-177 (177Lu)-labeled PTK7-targeted cyclized bivalent aptamer (CBSgc8) for treating an orthotopic hepatoblastoma. The cyclized multivalent design...
