Exosome Diagnostics, Inc., a developer of revolutionary, biofluid-based molecular diagnostics, today announced positive data from a large clinical validation study of its novel prostate cancer liquid biopsy test. The study met its primary endpoint demonstrating that the urine-based liquid biopsy test when added to the current prognostic standard of care (SOC) significantly improved the ability to accurately predict high-grade prostate cancer in men presenting for an initial biopsy. James McKiernan, M.D., John K. Lattimer Professor and Chair, Department of Urology at New York-Presbyterian Hospital/Columbia University Medical Center and principal investigator of the study, presented the data today in a late-breaking plenary session at the American Urological Association (AUA) Annual Meeting in New Orleans, La.
