A Study of [18]F-PSMA-1007 in Patients With Known or Suspected Metastatic Prostate Cancer

A \[18\]F-PSMA-1007 PET/CT or PET/MRI scan are nuclear medicine tests used to create pictures of the whole body that may show where cells that express Prostate-Specific Membrane Antigen (PSMA) are found. PSMA is a transmembrane protein that is overexpressed in the majority of prostate cancers. PSMA imaging utilizes this overexpression, by binding on the transmembrane receptor and internalization in the cancer cells. The internalized isotope can then be imaged with the use of a PET/CT or PET/MRI scanner and show where cancer cells may be present in the body. This imaging modality has been shown to be superior to conventional imaging, such as bone scan and CT, in the detection of prostate cancer tumors. The purpose of this study is to: 1) assess the clinical impact of a \[18\]F-PSMA-1007 scan on patient management plans; 2) assess the diagnostic effectiveness of a \[18\]F-PSMA-1007 scan in participants with known or suspected metastatic prostate cancer, as compared to standard of care CT chest, abdomen, pelvis and bone scan; 3) evaluate the safety of \[18\]F-PSMA-1007; and 4) assess potential correlations of PSMA level of uptake in certain tumors with cancer biologic markers such as PSA and Gleason score.
