Trial summary

68Ga-PSMA is a radiopharmaceutical used with PET imaging for the detection of prostate cancer under a compassionate IND in patients who have presented with biochemical failure. In this study, the use of 68Ga-PSMA-11 will be extended to newly diagnosed patients with high risk prostate cancer. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: This patient population will have Prostate cancer with planned surgical resection (GG2-5) of prostate cancer as part of routine clinical care or active surveillance/HIFU (GG1-3).

Who may be able to join

  • To be considered eligible to participate in this study, a patient must meet all the inclusion criteria listed below:
  • ≥ 18 years of age
  • Must provide written informed consent
  • Presence of high grade prostate cancer (Gleason grade group 1-5) on prostate biopsy or prostate cancer recurrence.
  • Scheduled for prostate cancer removal
  • Willing and able to lie still for approximately 30 minutes in an enclosed space for the 68Ga-PSMA-11 PET CT or MRI

Who cannot join

  • Participation in another investigational trial involving research exposure to ionizing radiation concurrently or within 30 days.
  • Significant acute or chronic medical, neurologic, or psychiatric illness in the subject that, in the judgment of the Principal Investigator, could compromise subject safety, limit the subject's ability to complete the study, and/or compromise the objectives of the study.

About this study

Official title: Pilot Ex-Vivo Investigation of an Experimental Beta Probe for Assessment and Guidance of Prostate Cancer Resection

68Ga-PSMA is a radiopharmaceutical used with PET imaging for the detection of prostate cancer under a compassionate IND in patients who have presented with biochemical failure. In this study, the use of 68Ga-PSMA-11 will be extended to newly diagnosed patients with high risk prostate cancer. Patients enrolled to this study will undergo a 68Ga-PSMA-11 PET/CT or PET/MRI scan for research purposes (in addition to the routine CT or MRI that is routinely done for staging), and a second 68Ga-PSMA-11 administration just prior to surgery for experimental ex-vivo beta probe testing of resected tissue. Immediately following resection of the prostate, the intact tissue will be scanned using a PET camera designed for animal research in order to record the 68Ga-PSMA-11 distribution in the isolated tissue at higher resolution than can be attained using whole-body PET imaging. The experimental beta probe will then be use to measure 68Ga-PSMA-11 counts of the resected tissue.

Read the detailed description

Primary Objective To assess beta ray detection of prostate cancer ex-vivo using experimental beta probe immediately after prostate cancer removal as determined by pathologist.

Secondary Objectives

  • Compare preoperative standard of care staging via CT or MRI to 68Ga-PSMA-11 PET (CT or MRI) findings.
  • Compare preoperative 68Ga-PSMA-11 PET (CT or MRI) lesion measurements with postoperative high-resolution PET of ex-vivo tissue.
  • To compare the findings of each of the 68Ga-PSMA-11 detection methods to the surgical observations and the clinical tissue histopathology findings.

Exploratory Objective Correlation of beta probe measurements with preoperative 68Ga-PSMA-11 PET (CT or MRI) lesion measurements, postoperative PET/CT ex-vivo images, surgical observations, and pathology findings.

What participants receive

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

  • Experimental beta probeOther

    3mCi (or similar) dose of 68Ga-PSMA-11 will be given prior to resection of cancer. Experimental beta probe designed to detect 68Ga-PSMA-11 will be used on prostate tissue after it has been surgically removed.

  • PSMA-PETDiagnostic test

    PSMA-PET imaging done prior to surgery and compared to whole mount imaging.

What is being measured

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

  1. Proportion of patients where prostate cancer was detected using the beta probe on excised prostate tissue

    Measured: 1 day

Secondary outcomes (4)
  1. Proportion of patients who had cancer detected by both the standard of care imaging (CT or MRI) and the 68Ga-PSMA-11 PET (CT or MRI) imaging

    Measured: 1 day

  2. Proportion of patients who had cancer detected by the beta probe on excised prostate tissue compared with surgical observations

    Measured: 1 day

  3. Proportion of patients who had cancer detected by the beta probe on excised prostate tissue compared with clinical tissue histopathology observations

    Measured: 1 day

  4. Comparison of pre-operative 68Ga-PSMA-11 (CT or MRI) lesions measurements with post-operative ex-vivo PET of prostate tissue

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

An observational study of Prostate Cancer, run by Indiana University at 2 sites 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 6 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 28 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

Proportion of patients where prostate cancer was detected using the beta probe on excised prostate tissue (time frame: 1 day). 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 NCT03213951, 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 28 Mar 2023.
