Decision Impact Study to Measure the Influence of DECIPHER on Treatment Recommendations (DECIDE)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02020876
Recruitment Status : Completed
First Posted : December 25, 2013
Last Update Posted : December 25, 2013
Information provided by (Responsible Party):
GenomeDx Biosciences Corp

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

Condition or disease Intervention/treatment
Prostate Cancer Other: DECIPHER Questionnaire

Detailed Description:
The primary and secondary objectives will be assessed in retrospectively selected prostate cancer patients treated with radical prostatectomy with one or more adverse pathological features (APFs)

Group/Cohort Intervention/treatment
Practicing urologic surgeons
Performing at least 60 radical prostate surgeries annually
Other: DECIPHER Questionnaire
Participants are asked to complete a questionnaire to assess the impact of Decipher on physicians' treatment recommendation. All participants use the same data collection instrument. Each participant opinion is collected based on a random selection of cases.

Primary Outcome Measures :
  1. Change in treatment recommendation [ Time Frame: 1.5 years ]

    To determine the extent to which the use of the Decipher test influences treatment recommendations by physicians post radical prostatectomy (RP).

    This decision impact study aims to evaluate Urologists' treatment recommendations before and after reviewing the results provided by the Decipher test.

Secondary Outcome Measures :
  1. Urologist's perception regarding the utility of the Decipher [ Time Frame: 1.5 years ]
    • Changes in Urologists expressed level of confidence in the treatment recommendation as measured by the response to item 4a in the eCRF survey.
    • Urologist's perception regarding the utility of the Decipher test as measured by the responses to question 4b and 38b and 38c in the eCRF survey.
    • Agreement in treatment recommendation
