Etarfolatide (EC20) is a conjugate of folic acid and peptidic metal-chelating moiety. Technetium Tc99m radiolabeled etarfolatide is a folate-targeted molecular imaging agent that is being developed to non-invasively identify tumors that express folate receptors and that may respond to folate-targeted therapy. It is being co-developed as the companion imaging agent to Vynfinit® (vintafolide) and EC1456 (folate-tubulysin).
