Arm Label
[18]F-PSMA-1007 PET/CT or PET/MRI
Arm Description
All participants will undergo a single [18]F-PSMA-1007 PET/CT or PET/MRI scan. Intravenous bolus injection of 4 MBq/kg +/- 10% of [18]F-PSMA-1007, up to a maximum of 400 MBq.
Outcomes
Primary Outcome Measures
Questionnaire based assessment of the impact of [18]F-PSMA-1007 PET/CT or PET/MRI on patient management plans
There is sparsity of evidence regarding the impact of the results of [18]F-PSMA-1007 PET/CT or PET/MRI on patient management. With this analysis we will study whether the treatment plan is modified with the findings of the [18]F-PSMA-1007 PET/CT or PET/MRI, by asking the referring physician to complete a questionnaire on paper or electronically (via REDCap). Questions will include the patient's clinical TNM stage, treatment intent (curative vs palliative), planned treatment modalities, and clinical confidence in their treatment plan, both before and after [18]F-PSMA-1007 imaging.
Secondary Outcome Measures
To confirm the diagnostic effectiveness of [18]F-PSMA-1007 PET/CT or PET/MRI in participants with known or suspected metastatic prostate cancer compared to standard of care cross-sectional imaging (CT chest, abdomen, pelvis)
A Nuclear Medicine physician will correlate the [18]F-PSMA-1007 PET/CT or PET/MRI findings with CT findings and comment on whether [18]F-PSMA-1007 avid lesions are visualized on standard of care imaging. The [18]F-PSMA-1007 PET/CT or PET/MRI scan findings will be compared globally to standard of care imaging to document if more or fewer lesions are seen on [18]F-PSMA-1007 PET/CT or PET/MRI than conventional imaging.
A reader confidence score will be used to assess reader certainty in finding characterization. The findings will be considered metastatic for scores 4 and 5.

A Nuclear Medicine physician will correlate the [18]F-PSMA-1007 PET/CT or PET/MRI findings with bone scan findings and comment on whether [18]F-PSMA-1007 avid lesions are visualized on standard of care imaging. The [18]F-PSMA-1007 PET/CT or PET/MRI scan findings will be compared globally to standard of care imaging to document if more or fewer lesions are seen on [18]F-PSMA-1007 PET/CT or PET/MRI than conventional imaging.
A reader confidence score will be used to assess reader certainty in finding characterization. The findings will be considered metastatic for scores 4 and 5.
The [18]F-PSMA-1007 level of avidity will be assessed in selected lesions and compared to background activity and cancer biologic markers (PSA value)
We will explore whether there is a correlation between [18]F-PSMA-1007 uptake and PSA values. The intensity of tumor uptake of [18]F-PSMA-1007 will be assessed by an experienced Nuclear Medicine physician using visual interpretation and computer-assisted techniques in up to five (5) lesions. The maximum Standardized Uptake Value (SUVmax) will be determined for the tumor site(s), the liver, blood pool and parotid using the standard algorithm available on the PET scanners.

5. Study Description
Brief Summary
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.
Detailed Description
This is a Phase II, diagnostic imaging, controlled, open-label, single site study in four cohorts of patients with known or suspected metastatic prostate cancer. All participants will be imaged with [18]F-PSMA-1007 PET/CT; [18]F-PSMA-1007 PET/MRI may be performed instead of a PET/CT, if PET/MRI is available.
The patients will be assessed for AEs after administration of [18]F-PSMA-1007, during their visit to the Nuclear Medicine Department. The assessment of impact on patient management will be performed using a questionnaire both before and after the [18]F-PSMA-1007 PET/CT or PET/MRI scan. The efficacy evaluation will consist of [18]F-PSMA-1007 PET/CT or PET/MRI clinical accuracy compared to standard of care CT and bone scan. Standard gadolinium-based contrast enhanced PET/MRI imaging may be performed if clinically indicated and if there are no contraindications. If a PET/MRI is performed, the clinical accuracy of the MRI component of the PET/MRI will be compared to the baseline CT. [18]F-PSMA-1007 uptake (SUVmax, Uptake Score) will be assessed in a selection of lesions and compared to PSA values collected on the day of the scan and Gleason score collected from the participant's medical history.
