About this study

Official title: 68Ga-PSMA-11 PET/CT for Staging of Intermediate and High Risk Prostate Cancer Prior to Radical Prostatectomy

This clinical trial studies how well 68Ga-PSMA-11 positron emission tomography (PET)/computed tomography (CT) works in imaging patients with intermediate or high risk prostate cancer before surgery. Diagnostic procedures, such as PET/CT scans, may help find and diagnose prostate cancer and find out how far the disease has spread.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To assess the sensitivity and specificity of gallium Ga 68 gozetotide (68Ga-PSMA-11) PET for the detection of regional nodal metastases compared to pathology at radical prostatectomy on a per patient basis, and on a per patient basis using nodal regional correlation.

SECONDARY OBJECTIVES:

  1. To assess the positive and negative predictive value of 68Ga-PSMA-11 PET for the detection of regional nodal metastases compared to pathology at radical prostatectomy on a per patient basis, and on a per patient basis using nodal regional correlation.

II. To assess sensitivity, specificity, positive and negative predictive value of 68Ga- PSMA-11 PET for the detection of extra-pelvic nodal metastases, visceral metastases and osseous metastases compared to biopsy and imaging follow-up.

OUTLINE:

Patients receive 68Ga-PSMA-11 intravenously (IV) and undergo PET/CT scan over 20-50 minutes on day 1.

After completion of study, patients are followed up at 2-4 days, then at 12 months.

Questions about this trial

What is this clinical trial studying?

A study testing Computed Tomography, Gallium Ga 68 Gozetotide and Positron Emission Tomography in people with Prostate Adenocarcinoma and Stage IIB Prostate Cancer AJCC v7, run by Jonsson Comprehensive 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 5 inclusion and 2 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 12 Apr 2023. 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.

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?

Sensitivity of 68Ga-PSMA-11 positron emission tomography for the detection of regional nodal metastases compared to pathology at radical prostatectomy on a per patient basis and using nodal regional correlation (time frame: Up to 12 months). 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 NCT03368547, which also lists 5 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 12 Apr 2023.
