The VISION clinical trial

A landmark for nuclear theranostics as prostate cancer treatment

For nuclear medicine specialists, 2021 may be heralded as a banner year validating the use of theranostic technology to treat cancer. Long-awaited results from an international phase 3 clinical trial showed that the addition of targeted radioligand therapy 177Lu-PSMA-617 to standard-of-care treatment in patients with metastatic castration-resistant prostate cancer significantly improved their overall and progression- free survival. “The success of the VISION trial is perhaps the most significant event of the past few decades and a major advance in the management of metastatic prostate cancer,” write nuclear medicine specialists Professor Wolfgang P. Fendler, M.D., and Professor Ken Herrmann, M.D., of the University of Duisburg Essen and German Cancer Consortium, and Matthias J. Eiber,…
