About this study
Prostate specific membrane antigen (PSMA) is a unique membrane bound glycoprotein, which is overexpressed manifold on prostate cancer cells and is well-characterized as an imaging biomarker of prostate cancer. Positron emission tomography / computer tomography (PET/CT) is a nuclear medicine procedure based on the measurement of positron emission from radiolabeled tracer molecules. 18F-DCFPyL is a tracer for prostate cancer PET imaging which binds to PSMA. The strength of functional imaging methods is in distinguishing tissues according to metabolism rather than structure. Studies have shown that PET/CT imaging with 18F-DCFPyL can detect prostate cancer lesions with excellent contrast and a high detection rate even when the level of prostate specific antigen is low.
The objective of this study is to evaluate if the patient-wide SUVmax on 18F-DCFPyL PET/CT in locoregional and metastatic prostate cancer correlates with histopathologic Gleason score at initial biopsy. It is hypothesized that SUVmax will correlate positively with Gleason score. This is of interest because non-invasive risk stratification may be possible in the future.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing 18F-DCFPyL PET/CT in people with Prostate Cancer, run by Sir Mortimer B. Davis - Jewish General Hospital at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
SUVmax on 18F-DCFPyL PET/CT (time frame: 24 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Feb 2019; AzTrials last refreshed its copy on 2 Nov 2026.
