  • Ages Any age
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult, Older adult

Study population: Physicians: Radiation oncologists targeted for recruitment into the study must meet the following criteria: * Practicing, board-certified radiation oncologists. * Perform consultations on at least 80 patients with prostate cancer annually. Patients: Patients diagnosed with localized prostate cancer that received radical prostatectomy as the first line treatment. De-identified patient cases were selected from an independent clinical validation study of patients with adverse pathology features treated between 2000 and 2006. (Karnes et al., 2013)

Case Inclusion Criteria:

Patient cases eligible for this study were treated with radical prostatectomy and have one or more adverse pathological features present defined as:

Pathological Gleason score ≥ 8 or Gleason score 7 with primary pattern 4; Pathological stage T3a (= Extracapsular extension) or T3b (=Seminal vesicle invasion); Positive surgical margins Gleason grade upgrade from biopsy to surgery Detectable PSA, defined as failure of PSA to fall to undetectable, or PSA detectable and rising on 2 or more subsequent determinations

Case Exclusion Criteria:

Metastatic disease (M+) prior to surgery Received any neo-adjuvant prostate cancer treatment prior to radical prostatectomy (radiation, hormone, chemotherapy)

About this study

Official title: GenomeDx Decipher Test for Metastatic Disease Prognosis in Prostate Cancer for Patients With Adverse Pathology Post Radical Prostatectomy: Does it Impact Radiation Oncologist' Treatment Recommendations?

This clinical utility study is based on a review of real but de-identified and randomized patient cases and aims to evaluate radiation oncologist's treatment recommendations before and after reviewing the results provided by the Decipher test. The primary intent is to help guide development and design of future clinical utility studies for Decipher.

Read the detailed description

Patient cases were selected using existing data generated from patient specimens collected in a separate IRB approved protocol, in which pathological specimens were tested to generate a test result for comparison to outcomes. Those test results are presented in this study, but not the individual patient outcomes. Physicians participating in this current study did not provide care for any of the subjects in the previous study. Cases are presented to physicians in a randomized order and in a form that prevents the patients from being identified, directly or indirectly.

High risk patient cases were selected to reflect a range of clinicopathological variables and were further stratified based on the Decipher predicted probability of developing metastasis 5 years after RP and 3 years after BCR (as shown in the table below). High (low) Decipher (GC) risk was defined as a 5- or 3-year predicted probability of metastasis greater (less) than 6% for the adjuvant setting and greater (less) than 18% for the salvage setting.

What participants receive

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

  • Decipher QuestionnaireOther

    Pathological data from 12 de-identified patient cases will be reviewed by at least 25 Radiation Oncologists before and after exposure to the Decipher test results. Given the number of patient cases, reviewed by each participant, this allows for assessment of decision making based on 300 patient case reviews at each time point, immediately following RP and at the time of PSA rise.

Questions about this trial

What is this clinical trial studying?

An observational study of Prostate Cancer, run by GenomeDx Biosciences Corp at 1 site in United States.

The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Feb 2016. 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?

Change in treatment recommendation (time frame: 12 months). 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 NCT02034812, which also lists 13 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 29 Feb 2016.
