Brief Summary:

Hypothesis:Anti-[18F]FACBC PET-CT will adequately detect local and extraprostatic recurrence, and lead to better characterization of disease status in restaging patients.

This is a study that will test a compound (chemical substance) that has a small amount of radioactivity attached to it. This substance has a natural tendency to go to prostate tissue. The substance is called [18]FACBC and it is given in the form of an injection into a vein. After the substance reaches the prostate, scans called PET or Positron Emission Tomography, are done. This is similar to having CAT scans or x-rays. Usually a compound called [18]FDG is used for PET scans but this substance is eliminated by the kidneys and cannot reach the prostate. This substance called [18]FACBC is not eliminated by the kidneys and may allow tumors in the prostate to be seen better. It is sometimes difficult to tell if a growth on the prostate is cancer with scans or x-rays that are usually done.

Anti-[18F]FACBC PET-CT will be compared to ProstaScint (In-capromab pendetide) which is the conventional imaging for prostate cancer. Investigators will be blinded of the intervention.

This study will look at how the [18]FACBC goes into the prostate tissue and determine its ability to detect recurrent prostate cancer.

Arm

Intervention/treatment

FACBC PET-CT and ProstaScint CT; Participants diagnosed with localized prostate carcinoma with subsequent definitive therapy or suspicion of recurrent cancer will undergo an FACBC PET-CT scan and the ProstaScinct CT.

Drug: FACBC; Anti-3-[18F]FACBC is an investigational positron emission tomography (PET) radiotracer being studies given intravenously prior to PET scan; Other Name: Fluciclovine Other: ProstaScinct; ProstaScint (In-Capromab Pendetide) is used to image the extent of prostate cancer in standard practice. Capromab is a mouse monoclonal antibody which recognizes prostate specific membrane antigen from prostate cancer cells and normal prostate tissue. It is given intravenously prior to undergoing CT imaging.; Other Name: In-Capromab Pendetide
