A Single Dose of 225Ac-RPS-074 Induces a Complete Tumor Response in an LNCaP Xenograft Model

Conclusion: A single dose of 148 kBq of 225Ac-RPS-074 induced a complete response in 86% of tumors, with tumor–to–normal-tissue ratios that predict an improved therapeutic index. The use of the macropa chelator enabled quantitative radiolabeling and may facilitate the clinical translation of this promising targeted α-therapeutic.
