FDA Approves new Blood Test for detection of High-Grade Prostate Cancer
The FDA has approved Cleveland Diagnostics’ IsoPSA, a blood-based test designed to help identify high-grade prostate tumors and guide biopsy decisions.
“FDA approval of our IsoPSA kit marks a significant milestone in Cleveland Diagnostics’ mission to help physicians and patients detect cancer early when it is most treatable and survivable,” shared Arnon Chait, PhD, company president and CEO. “We remain focused on executing our commercial strategy and expanding access to IsoPSA, to the benefit of patients nationwide.”
FDA approval of the IsoPSA test was based on clinical evidence from a large-scale, prospective study conducted at 14 sites across the U.S. and data from supporting analytical validation studies.
Prostate cancer is the second most common cancer in American men, with 1 in 8 diagnosed during their lifetime. In the U.S., greater than 1 million men undergo prostate biopsies each year, yet up to 75% of those follow-up tests are negative for high-grade disease. This diagnostic gap subjects millions to invasive, costly procedures that can produce physical risks, emotional stress, and significant healthcare costs. IsoPSA helps close this gap, giving clinicians and patients a more accurate risk assessment and greater confidence in biopsy decision-making.
“As a practicing urologist, I see firsthand how the limitations of current PSA testing can lead to unnecessary procedures and anxiety for patients and appreciate the critical need for early and accurate risk assessment and testing,” added Dr. Aaron Berger, Chief Medical Officer and Director of Clinical Research at Associated Urological Specialists in Chicago. “IsoPSA represents a meaningful advancement, giving physicians a tool that improves risk assessment and helps us make more informed biopsy decisions with greater confidence.”
“FDA approval underscores the value and clinical utility of IsoPSA in distinguishing benign elevations of PSA from those due to high grade cancer,” said Dr. Eric Klein, Emeritus Chair of the Glickman Urological & Kidney Institute at Cleveland Clinic and Distinguished Scientist at GRAIL, Inc.* “I’m very pleased to see this milestone achieved; it represents the culmination of extensive study and test development over the past decade.”
The IsoPSA IVD kit leverages Cleveland Diagnostics’ IsoClear™ platform. This proprietary technology investigates protein biomarkers at a structural level in the blood to provide clinically relevant insights into disease state.
