About this study
The investigators are imaging patients with prostate cancer using a new PET imaging agent (Ga-68-PSMA-11) in order to evaluate it's ability to detection prostate cancer in patients with high risk disease prior to prostatectomy.
Read the detailed description
Imaging and staging of prostate cancer is critical for surgical and treatment planning. Patients with suspected metastatic prostate cancer will be imaged using Gallium-68 labeled PSMA-11 in order to demonstrate its utility. The investigators plan to utilize this data to obtain further approvals of the Ga-68-PSMA-11 compound, so that this agent will become available for clinical imaging in prostate cancer patients. In the pre-prostatectomy population, the primary objective is to determine the sensitivity and specificity for detection on nodal metastasis.
This compound has been shown to be superior to choline based PET agents for the staging of prostate cancer, both Carbon-11 and Fluorine-18 compounds. But this compound was not patented and therefore no company or private entity will make the investment required to bring Ga-68-PSMA-11 to market. In the vacuum of availability, academic groups must take the lead in order to collect the necessary data for future FDA approval.

What is being measured
The primary outcome is the main question the study is designed to answer.
Sensitivity of PSMA PET for the Detection of Regional Nodal Metastases Compared to Pathology at Radical Prostatectomy
Sensitivity is defined as the ratio of the proportion of the patients who have the condition of interest and whose test results are positive over the number who have the disease. Patients who have a positive node on imaging and on pathology will be considered a true-positive. Patients who have no nodes on imaging and pathology will be considered true-negatives. Patients with positive nodes on imaging and negative on pathology will be considered false positives and those with positive nodes on pathology but negative on imaging will be considered false negatives. Follow-up scans for up to one year can be used in analysis
Measured: Up to 1 year
Specificity of of PSMA PET for the Detection of Regional Nodal Metastases Compared to Pathology at Radical Prostatectomy
Specificity is defined as the number of non-diseased participants correctly classified divided by all non-diseased individuals. Patients who have a positive node on imaging and on pathology will be considered a true-positive. Patients who have no nodes on imaging and pathology will be considered true-negatives. Patients with positive nodes on imaging and negative on pathology will be considered false positives and those with positive nodes on pathology but negative on imaging will be considered false negatives. Follow-up scans for up to one year can be used in analysis
Measured: Up to 1 year
Positive Predictive Value (PPV) of of PSMA PET for the Detection of Regional Nodal Metastases Compared to Pathology at Radical Prostatectomy
PPV is the proportion of patients with positive test who actually have the disease. Patients who have a positive node on imaging and on pathology will be considered a true-positive. Patients who have no nodes on imaging and pathology will be considered true-negatives. Patients with positive nodes on imaging and negative on pathology will be considered false positives and those with positive nodes on pathology but negative on imaging will be considered false negatives. Follow-up scans for up to one year can be used in analysis
Measured: Up to 1 year
Negative Predictive Value (NPV) of PSMA PET for the Detection of Regional Nodal Metastases Compared to Pathology at Radical Prostatectomy
NPV is the ratio of participants truly diagnosed as negative to all those who had negative test results. Patients who have a positive node on imaging and on pathology will be considered a true-positive. Patients who have no nodes on imaging and pathology will be considered true- negatives. Patients with positive nodes on imaging and negative on pathology will be considered false positives and those with positive nodes on pathology but negative on imaging will be considered false negatives. Follow-up scans for obtained up to one year after study scan be used in analysis.
Measured: Up to 1 year
Secondary outcomes (13)
Number of Participants With Grade 3 Treatment-related Adverse Events
All grade 3 and above adverse events were recorded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v4.0. The Investigator assigns grade, attribution of the possible association of the event with use of the investigational drug. The safety parameters include spontaneous reports of adverse events reported to the investigator by patients

Sensitivity of PSMA PET for the Detection of Extra-pelvic Nodal Metastases
Gallium 68 labeled PSMA-11 (68Ga-PSMA-11) positive lymph nodes will be considered for detection of extra-pelvic nodal metastases and assessed by change in size. Participants who if on follow-up imaging within 3-12 months, have lymph nodes which decrease by more than 30% or increase by more than 20% in short axis diameter (with a minimum of 3 mm in change in size) or with solitary lymph node regions show a decrease of Prostate-specific antigen (PSA) by >50% after targeted treatment and the lymph nodes do not change in size (less than 30% decrease or less than 20% increase in short axis diameter) will be counted as true positives. If on follow-up imaging, sites of initial 68Ga-PSMA-11 positive lymph node lesions < 30% without systemic therapy or focal therapy at this site or if 68Ga-PSMA-11 positive lymph node lesions that do not meet criteria for above false positive or true positive will be counted as false positives.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Ga-68 labeled PSMA-11 PET in people with Prostate Cancer, run by University of California, San Francisco at 1 site in United States.
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 7 inclusion and 4 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 10 Dec 2020. 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 United States. 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 combined 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.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 10 Dec 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Sensitivity of PSMA PET for the Detection of Regional Nodal Metastases Compared to Pathology at Radical Prostatectomy (time frame: Up to 1 year). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02919111, which also lists 2 linked publications.
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 10 Dec 2020.
