Prostate Carcinoma
Conditions
Brief summary
This clinical trial tests how well a urine prostate cancer screening test, My Prostate Score 2 (MPS2), integrated with magnetic resonance imaging (MRI) works for early detection of prostate cancer. MPS2 is an investigational urine-based test designed to help identify the likelihood of having aggressive prostate cancer. MPS2 testing works by measuring specific early detection biomarkers that include genetic information. This next-generation test aims to address a major challenge in prostate cancer care-detecting only the cancers that truly need treatment. Results may lead to paradigm shifts in early detection algorithms and reduce reliance on MRI and biopsy.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinically significant prostate cancer (csPCa), defined as Gleason Grade (GG) Group 2-5 | Up to 120 days | Will compare the proportions of patients with detected csPCa in the intervention and control arms (p1 and p2, respectively) using the OBrien Fleming stopping boundaries which control the overall one-sided Type I error rate to be less than .10. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of biopsies performed | Up to 120 days | Will be compared between arms using Farrington-Manning (score) tests for the difference in two independent proportions. |
| Detection of GG1 cancers | Up to 120 days | Will be compared between arms using Farrington-Manning (score) tests for the difference in two independent proportions. |
| Number of multiparametric magnetic resonance imaging performed | Up to 120 days | Will be compared between arms using Farrington-Manning (score) tests for the difference in two independent proportions. |
| Adherence to the management recommendations in the biomarker-based arm | Up to 120 days | — |
| My Prostate Score 2 (MPS2) performance for detecting csPCa | Up to 120 days | The sensitivity and specificity of MPS2 will be calculated using the established threshold both for a population of all patients (assuming patients without a biopsy do not have csPCa) and separately for patients with Prostate Imaging Reporting and Data System 3-5 who undergo a biopsy. |
| Cost | Up to 120 days | Will be compared between arms using Wilcoxon Rank Sum Tests due to expected skewed distributions. These analyses will be conducted as a 2-sided .05 alpha level. |
