About this study

Official title: Single-center Study for Biopsy Guidance Using Gallium-68 Labeled Prostate-specific Membrane Antigen (PSMA) PET/MRI in Patients With Elevated PSA Eligible for Prostate Biopsy in Comparison to Multiparametric MRI.

In 22% of patients with elevated Prostate-specific antigen (PSA) MRI guided biopsy will not detect significant prostate cancer (PCA) (defined as either: Gleason score (GS) ≥ 3+4 or tertiary pattern 5, or final stage ≥ pT3a and/or pN1). Therefore this study evaluates the ability of [68Ga]PSMA PET/MRI to detect and localize significant primary PCA to accurately direct prostate needle biopsy using the Gleason score from the histology of the core biopsies as standard of truth.

Read the detailed description

In this open label, single center, non-randomized, diagnostic study we plan to include 40 men with elevated PSA (ages 30-50 PSA >2.5 ng/mL; ages 50-80 PSA > 4ng/mL), which are assigned to a MRI guided biopsy.

These patients will undergo one additional PET/MRI scan with [68Ga]PSMA within two to three weeks before the biopsy (Arm A), or in case of an unclear/negative MRI scan but positive biopsy two to three weeks after biopsy (Arm B). In Arm A a radiologist will delineate the suspected areas on (A) multiparametric magnetic resonance image (mpMRI) and a nuclear medicine physician will delineate and color code the suspicious areas on the PET/MRI: (B) [68Ga]PSMA. The images will be loaded into the BiopSee® system. Lesions positive on both modalities will be labeled as "AB". Every suspicious lesion will be targeted with 3 cores. A maximum of 3 targets will be selected per patient.

For arm B: PET/MRI results will be correlated with the template biopsy results.

The data analysis of Arm A and Arm B will be identical. For the analysis the Gleason score from the histology of the core biopsies will serve as standard of truth.

After completion of the PET/MR study part - an amendment for PET/CT was submitted to the local ethics commity and acknowledged to include 10 more participants with PSMA PET/CT to investigate the use of PET/CT guided biopsy and intraoperative verivication of the target with a gamma counter.

What participants receive

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

  • [68Ga]PSMA-11Drug

    Also called PSMA PET/MRI

    PET/MRI with [68Ga]PSMA will be compared to mpMRI for biopsy guidance.

  • [18F]PSMA-1007Drug

    Also called PSMA PET/CT

    18F-PSMA-1007 PET/CT for biopsy guidance and intraoperative target verification.

PET/MRI before biopsyExperimentalPatients with suspected areas on mpMRI will undergo additional [68Ga]PSMA-11 PET/MRI scan with subsequent mpMRI and PET/MRI guided biopsy.
Receives: Drug: [68Ga]PSMA-11; Drug: [18F]PSMA-1007
PET/MRI after biopsyExperimentalPatients with unclear areas or a negative finding in the mpMRI for MRI guided biopsy but positive biopsy, which will undergo the additional [68Ga]PSMA-11 PET/MRI scan with [68Ga]PSMA.

What is being measured

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

  1. Rate of positive histopathology for [68Ga]PSMA-11 positive lesions

    PCA detection of PET/MRI versus mpMRI based on histopathology per patient and per prostate section.

    Measured: 7 months

Secondary outcomes (1)
  1. Correlation of [68Ga]PSMA-11 with tumor aggressiveness

    Correlation of stanadized uptake value (SUV) on [68Ga]PSMA-11 with Gleason Score on histopathology.

    Measured: 7 months

Questions about this trial

What is this clinical trial studying?

A study testing [68Ga]PSMA-11 and [18F]PSMA-1007 in people with Prostate Cancer, run by Irene Burger at 1 site in Switzerland.

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 5 inclusion and 8 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 2 Sep 2021. 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 Switzerland. 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.

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?

Rate of positive histopathology for [68Ga]PSMA-11 positive lesions (time frame: 7 months). 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 NCT03187990, 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 2 Sep 2021.
