Prospective Clinical Utility Study to Assess the Impact of Decipher on Treatment Decisions After Surgery

Not Applicable
Completed
Conditions
Prostate Cancer
Interventions
Other: Decipher
Registration Number
NCT02080689
Lead Sponsor
GenomeDx Biosciences Corp
Brief Summary

The influence of Decipher test on urologist and patient treatment plan choices immediately post RP and at the time of PSA rise or BCR

Detailed Description

This prospectively decision impact study will evaluate physicians and patient treatment plan choices before and after reviewing Decipher results for eligible patient cases. The clinical utility of Decipher will be evaluated for patients meeting the inclusion criteria at two time-points post-RP:

1. In the adjuvant setting: within 12 months after surgery (in the absence of detectable PSA rise of BCR)

2. In the salvage setting: post-RP with evidence of PSA rise or BCR (defined as PSA detectable and rising on 2 or more subsequent determinations)

A total of 150 patient cases, in each arm, will be prospectively selected from clinical sites. The study as a whole will enroll 300 patient cases.

As a condition of participation in the study, each clinical site must agree to provide a minimum of 10 patient cases.

Primary Outcome Measures
NameTimeMethod
Number of participants for which the Decipher test changes the urologist's and patient's treatment plan choices3 months
Secondary Outcome Measures
NameTimeMethod
Frequency of follow visits as a measure of reproducibility12 months

The extent to which the Decipher test results influence urologist recommendations on frequency of follow-up for patients

Measure the urologist's and patient's Level of confidence in their selected treatment plan through the use of a share decision making tool3 months
The number of different treatment plans most influenced by Decipher as a measure of clinical utility12 months
Measure the number of participants for which treatment was Increased or decreased in the intensity.3 months

This outcome will compare recommended treatment pre-Decipher to recommended treatment post-Decipher

Account for the number of specific treatment assignments that correlated with a change in treatment recommendation12 months
Assess the number of physicians that assigned the same treatment treatment recommendations for patient of the same pathological profile as a measure of concordance12 months
Evaluate number of participants which show coherence to treatment decisions12 months

For how many cases was the original selected treatment for a patient actually executed upon

Comparison of type of treatment plans between high risk and low risk patients6 months

How many treatment plans are similar for those considered at high versus low risk by Decipher test

A measure of the patient's quality of life (QOL) as a measure of Decipher's clinical utility for patients12 months

The extent to which the Decipher test results affect patient comfort level with treatment decisions as based on QOL and treatment regret tools
