“…Another post-hoc analysis from the VISION trial examined the correlation between several endpoints and the eventual survival endpoint. 22 There was a moderate-to-strong correlation between rPFS and OS, suggesting that rPFS may be relevant as an early endpoint for regulatory approval and clinical trial design in mCRPC patients undergoing radioligand therapy. The RALU study demonstrated that 177 Lu-PSMA therapy in patients previously treated with radium-223 (Ra223) had an acceptable safety profile and effectiveness in terms of OS and rPFS, and was similar to other findings with 177 Lu-PSMA, indicating no cross-resistance.…”
