Design outcomes

Primary

MeasureTime frame
Main Objective: Per-patient detection rate of 18F-DCFPyL PET/CT versus that of 18F-FCH PET/CT;Secondary Objective: Impact on patient treatment/management. Per-region detection rate of 18F-DCFPyL PET/CT versus that of 18F-FCH PET/CT. Sensitivity and specificity of 18F-DCFPyL PET/CT versus that of 18F-FCH PET/CT on a per-patient and per-region basis, using a composite SOR. Concordance rate between 18F-DCFPyL PET/CT and 18F-FCH PET/CT for regions using a composite SOR. Safety of 18F-DCFPyL versus that of 18F-FCH ;Primary end point(s): Per-patient detection rate of 18F-DCFPyL PET/CT and 18F-FCH PET/CT for recurrence (either local, regional or distant), based on the independent central reading. The detection rate is defined as the ratio between the number of patients defined as positive at patient level by at least 2 independent readers, and the total number of assessed patients.;Timepoint(s) of evaluation of this end point: Last patient last tracer injection

Secondary

MeasureTime frame
Timepoint(s) of evaluation of this end point: 10 months of follow-up after last patient last tracer injection.;Secondary end point(s): • Impact on patient treatment/management. • Per-region detection rate of 18F-DCFPyL PET/CT versus that of 18F-FCH PET/CT. • Sensitivity and specificity of 18F-DCFPyL PET/CT versus that of 18F-FCH PET/CT on a per-patient and per-region basis, using composite SOR. • Concordance rate between 18F-DCFPyL PET/CT and 18F-FCH PET/CT for regions using composite SOR. • Safety of 18F-DCFPyL versus that of 18F-FCH. The SOR will be made of an appropriate combination of tests performed in clinical routine practice during the following 10 months after the last 18F-tracer injection including: clinical data, PSA, histopathology and follow-up imaging exams. The per-region detection rate is the ratio between the number of patients defined as positive at region level for a given region by at least 2 independent readers and the total number of assessed patients. The per-patient sensitivity is the ratio between the number of patients defined as positive at patient level by at least 2 independent readers and the total number of patients assessed as positive at patient level by the truth panel. The per-region sensitivity is the ratio between the number of patients defined as positive at region level for a given region by at least 2 independent readers and the total number of patients assessed as positive at region level for the given region by the truth panel. The per-patient specificity is the ratio between the number of patients defined as negative at patient level by at least 2 independent readers and the total number of patients assessed as negative at patient level by the truth panel. The per-region specificity is calculated for each region as the ratio between the number of patients defined as negative at region level for the considered region by at least 2 independent readers and the total number of patients assessed as negative at region level for
