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 50 years and older

  • Adult, Older adult

Study population: Community Sample

Who may be able to join

  • Male, >50 years of age with a clinical suspicion for prostate cancer based in part on an elevated PSA (limit range: 2.0 - 20 ng/ mL), and or suspicious DRE, with or without the clinical history of a single prior negative biopsy, and who have been recommended for a repeat and or first time biopsy.
  • The subject must be able to comprehend and sign an approved informed consent form and other applicable study documents.

Who cannot join

  • Use of medications or hormones that are known to affect serum PSA levels within 3-6 months of study enrollment.
  • Clinical symptoms of urinary tract infection (including prostatitis) at the time of enrollment.
  • History of prostate cancer.
  • History of invasive treatments for benign prostatic hypertrophy (BPH) or lower urinary track symptoms within 6 months of study enrollment.
  • Medical history or concurrent illness that the investigator considers sufficiently serious to interfere with the conduct, completion or results of this trial, or constitutes an unacceptable risk to the subject.
  • Participation in pharmaceutical or treatment related clinical study within 6 months of study enrollment. Exception: Trials for non-prostate conditions may be acceptable, with approval by the investigator and Sponsor.
  • No known hepatitis (all types) and/or HIV documented in patient's medical record.
  • Patients with history of concurrent renal/bladder tumors within 6 months of study enrollment.

About this study

Validate a non-DRE exosome gene expression test, with an NPV >/= 90% certainty, will exclude the presence of high gleason grade/ score (>/=7) prostate cancer in a prostate needle biopsy.

Read the detailed description

The purpose of this multi-center clinical study is to determine the association of an Exosome Urine Test score with the presence of high Gleason grade / score (GS>/=7) prostate cancer on a prostate needle biopsy and validate the assay's performance characteristics in men presenting to their urologist with or without a previous negative biopsy, and recommended for an initial or subsequent biopsy. The results of this study are to support the use of this assay as a laboratory developed test. A secondary objective is to develop an assay that accurately predicts the presence of any Gleason grade prostate cancer in men at risk for prostate cancer.

What is being measured

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

  1. Correlate an exosome gene expression signature with the presence or absence of high grade prostate cancer in the prostate needle biopsy.

    Validate various thresholds utilizing the exosome RNA gene signature to stratify patients based on the likelihood of having any Gleason pattern 4 disease present within the biopsy (or when available the prostatectomy specimen surgical pathology report) for first time biopsy patients in the PSA gray zone of 2.0-10 ng/mL. In our earlier cohort analyses and in the literature there is an expected 20-25% of patients who will present with Gleason score >/=7 and the prevalence of a dominant Gleason 4 varies considerably dependent upon studies from 17-30%.

    Measured: one year

Questions about this trial

What is this clinical trial studying?

An observational study of Prostate Cancer, run by Exosome Diagnostics, Inc..

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 2 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 9 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

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?

Correlate an exosome gene expression signature with the presence or absence of high grade prostate cancer in the prostate needle biopsy. (time frame: one year). 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 NCT02702856, 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 9 Mar 2016; AzTrials last refreshed its copy on 8 Nov 2026.
