Metabolic Response by Fluciclovine F18 (18F-fluciclovine) Positron Emission Tomography (PET) With Standardized Uptake Values (SUV)" Primary · Up to 2 years

Will evaluate metabolic response by 18F-fluciclovine PET qualitatively and semi-quantitatively with SUV and correlate the findings with size changes as defined by conventional imaging prostate specific antigen (PSA) response. The percentage of change in the 18F-fluciclovine maximum standardized uptake value (SUVmax) after therapy will be calculated as follows (\[pretreatment corrected SUVmax - posttreatment corrected SUVmax\]/pretreatment corrected SUVmax) x 100. Similar calculations will be performed for mean SUV, metabolic tumor volume, and total volume activity. An analysis of the quantita

18F-fluciclovine PET Imaging Response - SUVMean Secondary · Up to 2 years

Will evaluate 18F-fluciclovine PET imaging response and its correlation with progression free survival defined by Prostate Cancer Working Group 2 criteria. SUVmean represents the average SUV value across a defined region of interest (ROI) in the tumor. The Measure Type is a number, that is dimensionless, because it is the average ratio of tissue activity concentration to the injected dose normalized by the patient's weight.

Sponsor's own description

This phase IV trial studies how well an investigational scan (18F-fluciclovine PET-CT) works for the measurement of therapeutic response in patients with prostate cancer that has spread to other places in the body (metastatic). 18F-fluciclovine is a radioactive substance that is used in this study with PET-CT imaging scans that may help doctors learn about response to standard therapy in patients with prostate cancer.
