“Our clinical study with over 15 of the leading and largest urology centers across the United States is the last step before our commercial launch of the 4Kscore™ in the first quarter of 2014. The data we generate in this clinical study will not only be used for the required CLIA validation, but will also provide important data for securing 4Kscore™ reimbursement,” stated David Okrongly, Ph.D., President of OPKO Diagnostics.About the 4Kscore™ Test The 4Kscore™ is a convenient blood test that measures the serum levels of four different prostate-derived kallikrein proteins: total PSA, free PSA, intact PSA and hK2. Levels of these biomarkers are combined with a patient’s age and digital rectal exam (DRE) status using a proprietary algorithm to calculate the probability of a finding of aggressive prostate cancer. The information provided by the 4Kscore™ test can help facilitate the shared decision-making process between urologist and patient in determining the advisability of a prostate biopsy. About Prostate Cancer In 2013, over 238,000 new cases of prostate cancer will be identified and 29,720 men will die from the disease, according to estimates released by the National Cancer Institute, making it the second most deadly cancer in U.S. men. Prostate cancer is usually first detected by elevations in serum PSA. However, PSA level is often high for reasons unrelated to prostate cancer and, since an elevated PSA level often leads to biopsy, 75% of all prostate biopsies performed are either negative or indicate a low likelihood of aggressive cancer.
