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 40 to 85 years
  • Men only
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: ConfirmMDx assay will be utilized to blindly test the needle biopsy cores of the index negative prostate biopsy (all cores) of men about to undergo repeat prostate biopsy. It is postulated that the test may aid in improved patient risk stratification for repeat biopsy, discriminating patients with no cancer/low grade prostate cancer (GS6) who are at sufficiently low risk to avoid repeat biopsy, while also identifying patients at increased risk for clinical significant disease (≥ GS7) who may benefit from early intervention. In this current study, SelectMDx will be used to blindly test urine samples obtained preceding a repeat prostate biopsy to validate the test's ability to predict risk for high-grade disease. The intent is to demonstrate the test's ability to non-invasively stratify those patients at risk for aggressive disease, who require a repeat prostate biopsy, versus those at sufficiently low risk who may avoid unnecessary repeat biopsy.

Who may be able to join

  • Males, aged 40 years to 85, who underwent a previous cancer-negative prostate biopsy within 30 months of being scheduled for a repeat biopsy.
  • The initial TRUS guided negative prostate biopsy must have collected a minimum of 10 tissue cores and sections from all prostate biopsy cores collected by the physician must be submitted to MDxHealth in order to allow for full comprehensive testing/evaluation of all the sections of the patient's prostate prior to the scheduled repeat biopsy.
  • Minimum tissue volume criteria of 20 microns of prostate biopsy core tissue is available (40 microns preferable).
  • Previous biopsy histology may include the presence of high-grade prostatic intraepithelial neoplasia (HGPIN), proliferative inflammatory atrophy (PIA), glandular inflammation, atypical small acinar proliferation (ASAP) or atypical cells.
  • Tissue was extracted using standard TRUS guided biopsy core extraction (and not transurethral resection of the prostate (TURP).
  • Pre-DRE serum sample, pre-DRE plasma sample, and Post-DRE urine sample to be collected in advance of the repeat biopsy. Samples can be collected within three months of the scheduled repeat biopsy, up until the day of, but prior to, the procedure.

Who cannot join

  • Patient who has undergone previously testing by ConfirmMDx from the same biopsy
  • Patients with prior diagnosis of prostate cancer in any previous biopsy.
  • Patients with a limited life expectancy and generally not considered for a repeat Tissue extracted using transurethral resection of the prostate (TURP) procedures
  • Patients with a history of cancer (except basal cell carcinoma)

About this study

Official title: Prospective Validation of Prostate Biomarkers for Repeat Biopsy: The PRIORITY Study

Target enrollment is 1000 prospectively enrolled subjects with an initial negative biopsy scheduled for repeat biopsy.

Subjects must have had their negative index prostate biopsy procedure within 30 months of being scheduled for their repeat biopsy.

All enrolled subjects will have all core tissues from the initial negative biopsy blinded and tested with the assay.

All subjects will have serum and plasma samples obtained prior to DRE, and a urine sample collected immediately following DRE but in advance of the repeat biopsy; samples will be blinded and sent to MDxHealth for evaluation.

What participants receive

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

  • ConfirmMDxDiagnostic test

    ConfirmMDx is a molecular diagnostic assay which utilizes DNA isolated from biopsy tissues to determine if aberrant DNA methylation is occurring in three genes: GSTP1, RASSF1 and APC. ConfirmMDx is currently available to clinicians for use in cancer-negative extended-core biopsies to determine if occult cancer is present in the prostate.

  • SelectMDxDiagnostic test

    SelectMDx for Prostate Cancer is a reverse-transcription PCR (RT-PCR) assay performed on post-DRE, first-void urine specimens from patients with clinical risk factors for prostate cancer, who are being considered for biopsy. The test measures the mRNA levels of the DLX1 and HOXC6 biomarkers, using KLK3 as internal reference gene, to aid in patient selection for prostate biopsy.

What is being measured

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

  1. Validate ConfirmMDx for Prostate Cancer to predict the outcome of repeat biopsy

    The primary objectives of this prospective, multi-center study are twofold:

    • Validate use of the ConfirmMDx for Prostate Cancer to predict the outcome of a repeat biopsy in men with a previous negative prostate biopsy using tissue.
    • Validate use of the SelectMDx for Prostate Cancer to predict the outcome of a repeat biopsy in men with a previous negative prostate biopsy using urine.

    Measured: 1 year

Secondary outcomes (1)
  1. Comparison between clinical and pathological outcomes

    Subset analyses conducted in appropriate groups, such as patients with available data from radical prostatectomy, and correlate this data with the ConfirmMDx and SelectMDx results.

    • Evaluate rate of cancer detection on repeat biopsy and associated complications.
    • Evaluate the findings of MRI fusion biopsy with standard 12 core TRUS guided biopsy (if available).

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Prostate Cancer, run by MDx Health 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 6 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 17 Aug 2018. 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?

Results are not available in the source record.

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?

Validate ConfirmMDx for Prostate Cancer to predict the outcome of repeat biopsy (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 17 Aug 2018.
