Brief Summary:
This pilot study aims to investigate the diagnostic utility of 18F-DCFPyL, a novel low-molecular weight PSMA PET/CT imaging agent, in men with an elevated PSA following radical prostatectomy.

Condition or disease Intervention/treatment Phase
Adenocarcinoma of the Prostate Drug: 18F-DCFPyL Not Applicable

Detailed Description:
18F-DCFPyL is a novel low-molecular weight PSMA imaging agent. A recent study of patients with metastatic prostate cancer found that PSMA PET/CT identified more sites of disease than conventional imaging with CT, MRI and bone scan. In this study we aim to investigate 18F-DCFPyL PET/CT in patients with an elevated PSA following radical prostatectomy. During the course of this study, patients will undergo two 18F-DCPyL PET/CT scans. The first scan will take place within 45 days of staging imaging and the second will take place following six months of standard of care therapy.

Primary Outcome Measures :
  1. Number of Putative Sites of Metastatic Disease as Determined by 18F-DCFPyL PET/CT [ Time Frame: 6 months ]
    Number of sites with 18F-DCFPyL uptake consistent with prostate cancer.

  2. Location of Putative Sites of Metastatic Disease as Determined by 18F-DCFPyL PET/CT [ Time Frame: 6 months ]
    Location of uptake of 18F-DCFPyL consistent with prostate cancer.


Secondary Outcome Measures :
  1. Correlation of 18F-DCFPyL PET/CT Findings With Prostate Specific Antigen (PSA) Levels [ Time Frame: 6 months ]
    Number of participants with PSA 0.2-1.0ng/mL OR PSA >1.0ng/mL with at least 1 site of uptake of 18F-DCFPyL consistent with prostate cancer.

  2. Correlation of Findings on 18FDCFPyL PET/CT With Those Found on Conventional Imaging (Bone Scan and Cross-sectional Imaging) [ Time Frame: 6 months ]
    Number of sites with uptake on 18F-DCFPyL PET/CT and corresponding lesions identified on conventional imaging.

  3. Correlation of Findings on 18F-DCFPyL PET/CT With Tissue Histology and PSMA Expression of Biopsied/Resected Pathology Specimens [ Time Frame: 6 months ]
    Number of sites with 18F-DCFPyL uptake from which biopsy specimens show PSMA expression.


Other Outcome Measures:
  1. Correlation of 18F-DCFPyL PET/CT Findings With Time to Disease Progression [ Time Frame: 6 months ]
  2. Assessment of Treatment Response by 18F-DCFPyL PET/CT [ Time Frame: 6 months ]
