OPKO to Discuss Draft Coverage Determinations for 4Kscore® Test at 2016 Jefferies Healthcare Conference

OPKO Health, Inc. (NYSE: OPK) today announced that senior management will discuss recent draft local coverage determinations by certain Medicare Administrative Contractors for OPKO’s 4Kscore® test at the Jefferies Healthcare Conference in New York City on Thursday, June 9, 2016 at 11:30 AM (EDT). OPKO previously announced that Novitas Solutions issued a positive draft local coverage determination proposing to establish reimbursement coverage for patients with PSA levels > 3 ng/mL who have not yet had a biopsy, or patients with a PSA level of > 3 ng/mL who have had at least one prior negative biopsy and are considered to be at higher risk. The draft coverage determination was subsequently retired by Novitas due to a potential conflict with another Medicare Administrative Contractor. Palmetto GBA had issued a draft non-coverage determination on May 27th for the 4Kscore test.

The 4Kscore test, extensively studied in over 22,000 patients with results presented in 12 peer reviewed scientific publications, improves health outcomes by avoiding unnecessary biopsies while accurately identifying men at high risk for a serious prostate cancer. The 4Kscore test has been adopted into NCCN guidelines and impacts physician and patient decisions while reducing healthcare costs. OPKO had not submitted complete dossiers to either Novitas or Palmetto in advance of their draft determinations and is providing both organizations with a complete data package including the background, extensive clinical validation and physician experience in support of the 4Kscore. OPKO believes there is more than enough scientific and clinical data to justify a positive local coverage decision by Medicare Administrative Contractors and intends to work closely with these organizations to demonstrate the value of the 4Kscore test to improve individual patient care as well as the efficiency of healthcare systems.

The Jefferies presentation will be webcast on the OPKO Investor Relations page of the corporate website at www.opko.com. To access the live webcast please log on to the OPKO site approximately fifteen minutes before the presentation to register and download any necessary audio software. The audio presentation will be available at this link for a limited time after the live presentation.

About the 4Kscore Test

4Kscore is the only blood test that accurately identifies an individual patient’s risk for aggressive prostate cancer, the lethal form of prostate cancer. The 4Kscore test uses a proprietary algorithm that incorporates the blood levels of four different prostate-derived kallikrein proteins: Total PSA, Free PSA, Intact PSA and Human Kallikrein-2 (hK2), plus the patient’s age and other clinical information to calculate the percentage risk (probability) of finding a Gleason Score 7 or higher grade of prostate cancer. The four kallikrein panel of biomarkers utilized in the 4Kscore test is based on over a decade of research conducted by scientists at Memorial Sloan-Kettering Cancer Center and leading European institutions and is included as a standard-of-care in the 2015 National Comprehensive Cancer Network’s Prostate Cancer Early Detection Guidelines. The 4Kscore Test provides individualized risk for the presence of aggressive prostate cancer and adds new information to the shared decision-making discussion between the physician and the patient.
