NECTIN4 and urothelial carcinoma: Furthermore, during the course of our work, Duan et al. were the first to report on a radiolabeled bicyclicpeptide targeting nectin-4 ([68Ga]­Ga–N188, denoted as 68Ga–N188 in the original publication), including preclinical and clinicalresults for imaging of urothelial carcinoma, which was later alsoexpanded to other tumor entities. Thedesign of [68Ga]­Ga–N188 corresponds to our approach; however, compared to the parent nectin-4-targetingpeptide BCY8126, the original homoarginine in position5 and 1-naphthylalanine in position 2 were substituted by arginineand 2-naphthylalanine, respectively.
