| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Cohort A | Experimental | 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. |
|
| Cohort B | No Intervention | Patients randomized to Cohort B will proceed with conventional standard of care. |

| ExoDx Prostate (IntelliScore) | Diagnostic Test | ExoDx Prostate (IntelliScore) is a non-invasive, urinary 3-gene expression validated test in which the results of the assay are adjunctive to the ordering physician's clinical judgment and work-up of the patient in the determination of whether a prostate needle biopsy is necessary. The ExoDx Prostate (IntelliScore) was clinically validated to discriminate patients with higher grade prostate cancer from those with more indolent lower grade cancer and benign disease. |
| Measure | Description | Time Frame |
|---|---|---|
| Evaluate performance of the ExoDx Prostate(IntelliScore) | Evaluate performance of the ExoDx Prostate(IntelliScore) to reduce the number of initial prostate biopsies by greater than or equal to 15% for men with an elevated prostate specific antigen between 2-10ng/mL presenting for a biopsy in consultation with their urologist. | 6 Months |

This is a prospective, randomized blinded, shared decision-impact and health-economic assessment study. 1000 appropriately screened consecutive patients seen during planning for a prostate biopsy will be enrolled. 500 patients will be randomized (blinded) to have the ExoDx Prostate (IntelliScore) test (Cohort A) and 500 (Cohort B) will proceed with conventional standard of care. At time of enrollment, neither the patient nor the urologist will be made aware of whether the patient will have an ExoDx Prostate (IntelliScore) test as part of their work-up. Cohort A EPI test results will be sent to the urologist for assessment and ultimately shared with the patient.
