Trial summary

The purpose of the study is to find out whether imaging of the prostate with a new molecule called 68Ga-PSMA can find prostate cancer. 68Ga-PSMA has been shown in a large number of patients to be useful to find recurring prostate cancer following initial cancer treatment.

About this study

Official title: 68GA-PSMA Fusion PET/MRI For Image-Guided Prostate Biopsies

The purpose of the study is to find out whether imaging of the prostate with a new molecule called 68Ga-PSMA can find prostate cancer. 68Ga-PSMA has been shown in a large number of patients to be useful to find recurring prostate cancer following initial cancer treatment. This study is performed to test 68Ga-PSMA whether it can be used to find prostate cancers that would be considered in need for treatment.

Read the detailed description

In this study, two different imaging tests are being compared: a) 68Ga-PSMA Positron Emission Tomography (PET)/Computed Tomography (CT) and b) Magnetic Resonance Imaging (MRI) of the prostate gland. Participants already have received the MRI, and the results were either suspicious of or definitive for prostate cancer. Both tests (MRI and 68Ga-PSMA PET/CT) are expected to show tumor tissue when more aggressive, but one test could be more accurate than the other test.

Another important question is whether these imaging tests will perform as good or better than prostate biopsies in finding all prostate cancer lesions in need for treatment. If imaging would be comparable or better than biopsies, then imaging may be able to replace invasive biopsies for some indications in the future.

To investigate these questions, participants are asked to undergo a 68Ga-PSMA PET/CT before a planned prostate biopsy procedure. After the biopsy procedure is performed, investigators will compare the imaging results from 68Ga-PSMA with those from the MRI and determine which test is more accurate.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 68Ga-PSMADrug

    Also called Gallium-68 PSMA-HBED-CC, Gallium-68 PSMA-11

    Positron Emission Tomography/Computed Tomography (PET/CT) imaging with 68Ga-PSMA:

    68Ga-PSMA is an investigational radioactive drug that binds to receptors on prostate cancer cells. The intravenously administered drug dose will be about 5 mCi (range 3-7 mCi).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparison of Two Different Radiologic Imaging Techniques, Fusion PET/MRI and Standard MRI, With Histopathologic Reference Data From Prostate Biopsy

    Fusion PET/MRI is the combination of 68Ga-PSMA Positron Emission Tomography/Computed Tomography (PET/CT) plus Multiparametric MRI (mpMRI)-guided biopsy. Reference standard will be pathology-defined as targeted plus standard prostate biopsy, and prostatectomy, when available. The original intent was to determine the sensitivity and specificity of standard-of-care Multiparametric MRI (mpMRI) alone (using PI-RADS version 2) and fusion PET/MRI for the detection of primary Gleason ≥3+4 cancer, and to estimate the positive likelihood ratio (LR) of each. However, due to pandemic-related early closure of the study, enrollment was less than 15% of the enrolment goal necessary to achieve statistical power. Therefore, it is not possible to responsibly report the originally listed outcome measure of likelihood ratio. Instead, the results table displays the summary of collected imaging data, categorized by type of scan, in comparison to the reference standard histopathology.

    Measured: Up to ~4 weeks (after planned, standard-of-care biopsy).

Secondary outcomes (1)
  1. Adverse Events of 68Ga-PSMA Administration

    Adverse events will be determined through clinical assessment and categorized by CTCAE 4.0.

    Measured: 24 hours post injection

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 68Ga-PSMA in people with Prostate Cancer, run by University of Michigan Rogel Cancer Center 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 3 inclusion and 9 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: stopped early, as of the sponsor's last update on 5 Jan 2022. 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 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?

Yes. Results are posted in the registry (first posted 5 Jan 2022). 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?

Comparison of Two Different Radiologic Imaging Techniques, Fusion PET/MRI and Standard MRI, With Histopathologic Reference Data From Prostate Biopsy (time frame: Up to ~4 weeks (after planned, standard-of-care biopsy).). 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 NCT03689582, which also lists 1 linked publication.

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 5 Jan 2022.
