Design outcomes

Primary

MeasureTime frame
Main Objective: -Response evaluation of patients treated with 223RaCl2 (Xofigo®, Bayer) using 68Ga-PSMA imaging PET; - Evaluate if PSMA-PET response can be used as a biomarker to predict survival in patients treated with 223RaCl2 (Xofigo®, Bayer).;Secondary Objective: - Comparison of PSMA-PET results with a validated imaging (bone scintigraphy); -Correlation of PSA and ALP changes with results of PSMA-PET; -Correlation of PSMA-PET response with time to first symptomatic skeletal event (SSE). ;Primary end point(s): Response evaluation of patients treated with 223RaCl2 (Xofigo®, Bayer) using 68Ga-PSMA imaging PET;;Timepoint(s) of evaluation of this end point: 20 months

Secondary

MeasureTime frame
