Cleveland Diagnostics Announces Publication of Multicenter IsoPSA Clinical Validation Study Demonstrating Improved Accuracy Over Prostate-Specific Antigen Test

The study, led by Eric Klein, M.D., chairman of Cleveland Clinic’s Glickman Urological & Kidney Institute, involved leading researchers from Cleveland Clinic, Johns Hopkins, University of Texas Southwestern, Kaiser Permanente Northwest, Rabin Medical Center (Israel), and other academic and community clinical sites.

“We now have extensive clinical evidence that supports our technology and the ability of IsoPSA to meaningfully change the current clinical paradigm in prostate cancer diagnosis,” said Arnon Chait, Ph.D., CEO of Cleveland Diagnostics. “We continue to work towards the appropriate regulatory approvals to get IsoPSA into the hands of physicians as soon as possible.”

The multicenter study compared the diagnostic accuracy of Cleveland Diagnostics’ IsoPSA technology to that of PSA, the current standard of care in prostate cancer, in men scheduled for prostate biopsy. The results echoed those from a preliminary study, demonstrating that IsoPSA has much greater diagnostic performance than PSA in identifying which patients have high-grade disease.

“The superior clinical performance stems from the underlying technology, which effectively classifies proteins based on cancer-specific changes to their structure, rather than overall concentration in blood – which is not cancer-specific. This first-in-class scientific approach can be extended to a number of cancers and neurodegenerative diseases, which we are currently exploring,” said Chait. The results of the study show that IsoPSA could reduce unnecessary biopsies by at least 45 percent, saving men from unneeded invasive and expensive procedures that can sometimes lead to serious and lasting side effects. Future indications for IsoPSA could also include active surveillance and direct replacement of PSA for screening in the primary care environment, while still maintaining a similar cost structure.

Cleveland Diagnostics has several clinical collaborations around the world, including underserved areas in Africa and India. “A unique advantage of IsoPSA is that it does not require highly specialized or expensive equipment or reagents to run samples,” said Aimee Kestranek, Vice President of Operations at Cleveland Diagnostics. “We have set up clinical sites in a matter of hours due to the ease-of-use of the IsoPSA technology.”

Dr. Klein has no personal financial interest in the company.
