Primary Outcome Measures
NameTimeMethod
Main Objective: The primary aim of this first line 177Lu-PSMA RLT study is to evaluate the clinical efficacy in castration resistant metastatic prostate cancer. Secondary aims are to assess the progression free survival (radiographic, clinical or PSA progression free survival), the response to 177Lu-177 PSMA RLT (RECIST 1.1, metabolic, biomarkers), the safety and tolerability, the health-related quality of life assessment and pain assessment, and the overall survival.;Secondary Objective: Not applicable;Primary end point(s): The primary endpoint is the therapy response defined as decline of PSA value of > 50%. ;Timepoint(s) of evaluation of this end point: 24 months after last radioligand therapy.
