Ex-vivo Investigation of Beta Probe for Prostate Cancer Resection and Evaluation of PSMA-PET for Diagnosis of Intraprostatic Lesions

NCT03213951

Description:

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.

Purpose

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.

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.

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.

    Eligibility Criteria

            Inclusion Criteria
    
            To be considered eligible to participate in this study, a patient must meet all the
            inclusion criteria listed below:

              2. Must provide written informed consent
    
              3. Presence of high grade prostate cancer (Gleason grade group 1-5) on prostate biopsy or
                 prostate cancer recurrence.
    
              4. Scheduled for prostate cancer removal
    
              5. Willing and able to lie still for approximately 30 minutes in an enclosed space for
                 the 68Ga-PSMA-11 PET CT or MRI
    
            Exclusion Criteria
    
              1. Participation in another investigational trial involving research exposure to ionizing
                 radiation concurrently or within 30 days.
    
              2. 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.
