PROSTest test in men with elevated PSA to aid prostate cancer decisions
Official title: A Single-arm, Multicenter Prospective Study to Evaluate the Diagnostic Performance of PROSTest in Men With PSA ≥ 3ng/ml Using Biopsy as the Sole Ground Truth
Run by Wren Laboratories LLC · NCT07454603 · Data updated 2026-11-12
This study tests PROSTest in men with elevated PSA to see if it can accurately detect prostate cancer using biopsy results as the reference.

Is this trial a fit for you?
✓Likely a good fit
Men with elevated PSA and/or abnormal digital rectal examination being referred for a prostate biopsy, willing to provide a blood sample before biopsy.
✕Probably not a fit
Men without elevated PSA/abnormal exams or those with prior prostate cancer diagnosis may not benefit from this diagnostic approach.

What this trial studies
This prospective, multicenter study enrolls men referred for prostate biopsy due to elevated PSA or abnormal exam, with or without pre-biopsy MRI. Blood is collected before biopsy for PROSTest analysis, and biopsy pathology serves as the ground truth. PROSTest results are analyzed blinded to pathology, and diagnostic performance metrics like sensitivity, specificity, and AUC will be reported. Additional analyses will examine how PROSTest scores relate to MRI findings and Gleason grade group, and whether PROSTest could reduce unnecessary biopsies through decision-curve analysis.
Why it matters
Potential benefit: If successful, PROSTest could improve accuracy and reduce unnecessary biopsies for men at risk of prostate cancer.
How similar studies have gone: Previous studies have explored biomarker tests alongside imaging; this study adds prospective, blinded analysis with biopsy as the reference standard.
