PSMA-directed EndoRadiotherapy of Castration-resISTant prostate cancer (PERCIST). IND # 133661


This is a targeted radionuclide therapy for metastatic Castration resistant (Hormone refractory) prostate cancer.  This treatment is offered for the first time in U.S.

I would highly appreciate if you can inform the patients regarding the availability of this treatment at our center. The treatment appears to be very promising. Attached, please find a recently published peer reviewed manuscript regarding this treatment. Following is one example of patients benefited from this therapy:
