Which is Better, 177Lu-PSMA-617 (Pluvicto) or Xofigo (Radium-223)

Several men have asked us if they are better off having 177Lu-PSMA-617 (Pluvicto) or Xofigo, a radiopharmaceutical drug that treats bone metastases. There is no simple answer, and the answer is not the same for each of us. Making a sound decision can be helped by understanding the mode of action and the limits of each treatment.

The trial showed that the LuPSMA treatment delayed prostate cancer progression versus Jevtana, with a comparable benefit observed in radiographic progression-free survival and PSA progression-free survival.

The Efficacy of PSMA Scans and Therapy

In this first study to analyze PSMA-targeted radionuclide therapy response via imaging expression, the results demonstrated that the PSMA expression level is associated with response likelihood. However, negative imaging does not exclude all men who may benefit from PSMA therapy.

Evaluating PSMA-Targeted Radionuclide Therapy

This study did demonstrate that the level of PSMA expression of a man’s prostate cancer, the stronger the association with the likelihood of their having a PSA response. 

177Lu-PSMA-617 Clinical Trials

Endocyte, Inc. announced that it has enrolled the first man into its phase 3 VISION study of 177Lu-PSMA-617 as a clinical therapy.  Cancer ABCs has had a number of men asking about the trial.

VISION is an open-label, randomized trial assessing the addition of radiolabeled prostate-specific membrane antigen to standard therapy for PSMA-positive, previously treated metastatic castration-resistant prostate cancer (mCRPC). The study will enroll 750 men in total, with the primary endpoint being overall survival.

Currently, there are six different trials evaluating 177Lu-PSMA-617 actively recruiting men worldwide.  In the United States they are at Weill Cornell Medical Center in New York, UCLA in Los Angles, and one site in Houston Texas.  There are also trials in multiple locations in the UK, in Italy and in Australia.  For additional trial information and locations go to
