E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Sensitivity and specificity of [18F]-FCH PET/CT for systemic disease (i.e., lymph node metastases and/or organ metastases and/or bone metastases) on a body region basis. |
|
E.2.2 | Secondary objectives of the trial |
• Sensitivity and specificity of [18F]-FCH PET/CT for lymph node metastases using histopathology as the SOR and CT as a comparator (per lymph node area; only lymph nodes area with histopathological analysis).
• Agreement rate between [18F]-FCH PET/CT and CT for organ metastases on a region basis. Discrepant cases will be documented by MRI. For lung metastases, discrepant results will be documented by a chest CT performed within 6 monthsafter [18F]-FCH PET/CT.
• Agreement rate between [18F]-FCH PET/CT and bone scintigraphy with regard to bone metastases (on a body region basis). Discrepant cases will be documented by MRI.
• Sensitivity and specificity of [18F]-FCH PET/CT for systemic disease (i.e., lymph node metastases and/or organ metastases and/or bone metastases) on a patient basis.
• Agreement between [18F]-FCH PET/CT and pelvic MRI for the primary tumor.
• Modification of tumor primary staging and patient management.
• Safety of [18F]-FCH

E.5 End points |
E.5.1 | Primary end point(s) |
Sensitivity and specificity of [18F]-FCH PET/CT for primary staging of prostate cancer |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
End of the study through a blinded central read |
|
E.5.2 | Secondary end point(s) |
•Sensitivity and specificity of [18F]-FCH PET/CT for lymph node metastases using histopathology as the SOR and CT as a comparator (per lymph node area; only lymph nodes area with histopathological analysis). Quantification using SUV (quantitative uptake in lymph nodes) will be used.
•Agreement rate between [18F]-FCH PET/CT and CT for organ metastases on a region basis. Discrepant cases will be documented by MRI (except for lung metastases). For lung metastases, discrepant results will be documented by a chest CT performed within 6 months after [18F]-FCH PET/CT.
•Agreement rate between [18F]-FCH PET/CT and bone scintigraphy with regard to bone metastases (on a body region basis). Discrepant cases will be documented by MRI.
•Sensitivity and specificity of [18F]-FCH PET/CT for systemic disease (i.e., lymph node metastases and/or organ metastases and/or bone metastases) on a patient basis.
•Agreement rate between [18F]-FCH PET/CT and pelvic MRI (if available) for the primary tumor.
•Modification of tumor primary staging and patient management.
•Safety of [18F]-FCH

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
The end of the trial will take place when the last patient undergoing the trial will have finished the follow up period. The follow up period may contain additional imaging tests (MRI or chest CT) which have to be done within 6 months after injection of the study product. The additional imaging tests concern patients with
discrepant results between [18F]-FCH and CT or bone scintigraphy. |
