Design outcomes

Primary

MeasureTime frame
Main Objective: Primary objective is to evaluate 18F-FDHTPET/CT as an early treatment response marker in patients with metastasized CRPC to be treated with enzalutamide. ;Secondary Objective: Secondary objective is to collect biopsies of prostate cancer bone and/or lymph node metastases, blood and urine specimens for future research. ;Primary end point(s): Association of 18F-FDHT PET/CT prior to start of enzalutamide (study week 1) with treatment response. Association of delta (study week 1 and 5) 18F-FDHT PET/CT with treatment response. ;Timepoint(s) of evaluation of this end point: See above E.5.1.

Secondary

MeasureTime frame
Secondary end point(s): Collection and storage of biomaterial for future research.;Timepoint(s) of evaluation of this end point: Prior to start of enzalutamide (study week 1) and after 12 weeks of treatment (study week 13)
