Decision Impact Trial of the ExoDx Prostate (IntelliScore)

Not Applicable

• Conditions: Cancer of the Prostate
• Interventions: Diagnostic Test: ExoDx Prostate (IntelliScore)

• Registration Number: NCT03235687
• Lead Sponsor: Exosome Diagnostics, Inc.

Brief Summary

The purpose of this research study is to investigate the utility of a validated urine test which predicts the likelihood of high grade prostate cancer on an initial prostate biopsy.

Detailed Description

Primary Objective(s)

1. Evaluate performance of the ExoDx Prostate(IntelliScore) (EPI) to reduce the number of initial prostate biopsies by greater than or equal to 15% for men with an elevated Prostate-Specific Antigen 2-10ng/mL presenting for a biopsy in consultation with their urologist.

2. Compare performance of both the ExoDx Prostate(IntelliScore) 15.6 and 20 cut-points with respect to the biopsy decision process.

3. Assess physician satisfaction with the ExoDx Prostate(IntelliScore) report including test result presentation, graphics and interpretation.

4. Assess urologist / patient satisfaction for ease of understanding test results and role on biopsy decision process.

Secondary Objectives

1. Determine the medical economic impact of the ExoDx Prostate(IntelliScore) test in the prostate biopsy decision process.

2. Correlation of the ExoDx Prostate(IntelliScore) score with the actual biopsy result by utilizing the Receiver Operating Characteristic of the Area Under Curve for discriminating high-grade (greater than or equal to Gleason Score 7, International Society of Urological Pathology 2 and 3) from low-grade (Gleason Score 6, International Society of Urological Pathology 1) and benign disease on initial prostate needle biopsy.

Arm && Interventions

Group	Intervention	Description
Cohort A	ExoDx Prostate (IntelliScore)	Patients randomized to Cohort A will receive ExoDx Prostate (IntelliScore) test results along with a post-ExoDx Prostate (IntelliScore) test result questionnaire to evaluate impact of test results in the biopsy decision process, utility, ease of understanding and work-flow implementation.
