OPKO Presents Additional Data on RAYALDEE® at ENDO 2016

MIAMI--(BUSINESS WIRE)-- OPKO Health, Inc. (NYSE:OPK), announced that additional data on RAYALDEE as a treatment for secondary hyperparathyroidism (SHPT) will be highlighted later today in a poster presentation at the Endocrine Society's 98th Annual Meeting, underway in Boston, MA. The data showed that mean plasma levels of intact parathyroid hormone (iPTH) and other markers of elevated bone metabolism gradually fell with RAYALDEE treatment as serum total 25-hydroxyvitamin D (25D) rose above 30 ng/mL, a level considered sufficient for chronic kidney disease (CKD) patients in published clinical practice guidelines. No association was apparent between serum calcium or phosphorus and 25D levels rising to > 80 ng/mL. These data suggest that patients with stage 3 or 4 CKD require higher levels of serum 25D than previously thought in order to reach vitamin D sufficiency and to optimally control elevated iPTH, and that such levels are well tolerated.

OPKO's poster presentation entitled "Treatment Effects of Modified-Release Calcifediol on Bone Markers Suggest Higher 25-Hydroxyvitamin D Levels Are Needed for Adequacy in Patients with Stage 3 or 4 CKD," will be presented by lead author Stuart M. Sprague, DO, Chief, Division of Nephrology and Hypertension, NorthShore University Health System - University of Chicago, Pritzker School of Medicine.

About RAYALDEE

RAYALDEE (calcifediol) extended-release capsules are pending approval by the U.S. Food and Drug Administration (FDA) for the treatment of SHPT in adult patients with stage 3 or 4 CKD and vitamin D insufficiency. RAYALDEE has a proprietary formulation designed to raise serum total 25-hydroxyvitamin D (prohormone) concentrations to targeted levels (at least 30 ng/mL) and to reduce elevated iPTH. RAYALDEE is expected to be launched in the U.S. by OPKO's dedicated sales force in 2H 2016.

About Chronic Kidney Disease

CKD is a condition characterized by a progressive decline in kidney function. The kidney is normally responsible for excreting waste and excess water from the body, and for regulating various hormones. CKD is classified in five stages — mild (stage 1) to severe (stage 5) disease — as measured by the kidney's glomerular filtration rate. According to the National Kidney Foundation, CKD afflicts over 26 million people in the U.S., including more than 20 million patients with moderate (stages 3 or 4) and severe (stage 5) forms of CKD. In stage 5 CKD, kidney function is minimal to absent and patients require regular dialysis or a kidney transplant for survival.

About Vitamin D Insufficiency

Vitamin D insufficiency is a condition in which the body has low vitamin D stores, characterized by inadequate blood levels of vitamin D prohormone, known as 25D. An estimated 70-90% of CKD patients have vitamin D insufficiency, which can lead to SHPT and resultant debilitating bone diseases. Vitamin D insufficiency has been associated with increased mortality in CKD.

About Secondary Hyperparathyroidism (SHPT)

SHPT is a condition commonly associated with CKD in which the parathyroid glands secrete excessive amounts of parathyroid hormone (PTH). SHPT arises as a result of vitamin D insufficiency or impaired kidney function that prevents sufficient production of vitamin D hormone to properly regulate calcium and phosphorus metabolism, and PTH secretion. Prolonged elevation of blood PTH causes excessive calcium and phosphorus to be released from bone, leading to elevated serum calcium and phosphorus, softening of the bones (osteomalacia) and calcification of vascular and renal tissues. SHPT affects 40-60% of patients with moderate CKD and approximately 90% of patients with severe CKD.
