68Ga-PSMA PET/CT in Prostate Cancer

Sir Mortimer B. Davis - Jewish General Hospital540 enrolled

Overview

The objectives of this study are to replicate the safety and efficacy of 68Ga-PSMA PET/CT and as a diagnostic and decision making tool in the management prostate cancer patients.The primary endpoints of the study are the incidence of adverse events (AE) in the study population up to 7 days following the scan, and the sensitivity and specificity of 68Ga-PSMA PET/CT vs CT on a per-patient and per-lesion basis.

Positron emission tomography / computer tomography (PET/CT) is a nuclear medicine diagnostic imaging procedure based on the measurement of positron emission from radiolabeled tracer molecules in vivo. A radiotracer in use today is 68Ga-HBED-CC-PSMA (DKFZ-11) - hereinafter abbreviated 68Ga-PSMA - which is a radiolabeled urea-based ligand for prostate specific membrane antigen (PSMA) PET/CT. Imaging with 68Ga-PSMA PET is used to characterize and localize prostate cancer in humans in vivo. There is extensive data in the literature showing the value of 68Ga-PSMA PET/CT imaging in accurately staging and restaging prostate cancer. The objectives of this study are to replicate the safety and efficacy of 68Ga-PSMA PET/CT and to establish our ability to reproduce results from the literature using 68Ga-PSMA PET/CT as a diagnostic and decision making tool in the management prostate cancer patients. During the study eligible prostate cancer patients will undergo one 68Ga-PSMA PET/CT. The primary endpoints of the study are the incidence of adverse events (AE) in the study population up to 7 days following the scan, and the sensitivity and specificity of 68Ga-PSMA PET/CT vs CT on a per-patient and per-lesion basis.
