OPKO Health Submits De Novo Request to the U.S. FDA for the 4Kscore® Test

MIAMI, June 20, 2019 (GLOBE NEWSWIRE) -- OPKO Health, Inc. (NASDAQ: OPK) announces that the Company has submitted a de novo request to the U.S. Food and Drug Administration (FDA) seeking regulatory clearance for the 4Kscore® test. The 4Kscore® test is a blood test used by health care professionals to assess a patient’s risk of having aggressive prostate cancer after an abnormal prostate specific antigen (PSA) test result, and before a decision is made to perform a biopsy.

The de novo pathway for approval is available to medical devices of low-to-moderate risk that do not have an approved predicate device.  Per FDA guidelines, the Company expects to receive a response to this request within approximately 180 days.

“We are happy to report the submission of our regulatory filing to the FDA for the 4Kscore® test.  In multiple prospective controlled clinical studies, the 4Kscore® test has shown consistent high sensitivity and high predictive values to identify men at higher risk of aggressive prostate cancer and who will benefit from a prostate biopsy, while  helping to avoid biopsies in men who are at low risk,” said Phillip Frost, M.D., OPKO's Chairman and Chief Executive Officer.  “We believe FDA clearance for the 4Kscore® test will help to maximize its market availability and reimbursement.”

The four biomarkers included in the 4Kscore® test are the result of more than a decade of research by scientists in Europe and the U.S., including scientists from the University of Turku and Memorial Sloan Kettering Cancer Center.  Through extensive research and multiple prospective controlled clinical validation studies, including large long-term outcome studies, the 4Kscore® test with its algorithm in place for the last several years, has been shown to stratify subjects into low- and high-risk groups for future prostate cancer metastasis and mortality.  The 4Kscore® test has been included in the National Comprehensive Cancer Network Guidelines® (NCCN) and American Urological Association guidelines since 2015, and the European Association of Urology Prostate Cancer Guidelines since 2016.

OPKO has offered the 4Kscore® test since 2014 in the U.S. and Europe.
