OPKO Health to Present New Clinical Data on Rayaldee (ER Calcifediol) at Kidney Week 2023

MIAMI, Oct. 25, 2023 (GLOBE NEWSWIRE) -- OPKO Health, Inc. (NASDAQ: OPK) will present late-breaking clinical data on RAYALDEE® extended-release calcifediol (ERC) at the American Society of Nephrology (ASN) Kidney Week in Philadelphia on Thursday, November 2, 2023. These data will be presented in a poster, “Control of Secondary Hyperparathyroidism with Extended-release Calcifediol is Associated with Slower CKD Progression” (#TH-PO1152) at 10:00 a.m. Eastern time in Exhibit Halls B-D by authors Charles W. Bishop Ph.D., Stephen A. Strugnell Ph.D. and Akhtar Ashfaq, M.D., FACP, FASN.

OPKO Health will present two other posters at ASN Kidney Week summarizing additional new clinical data on RAYALDEE. One poster, “Extended-release Calcifediol Overcomes Impact of Low eGFR on Vitamin D Metabolism” (#FR-PO319), will be presented in the “Bone and Mineral Metabolism: Basic” session at 10:00 a.m. Eastern time on Friday, November 3, 2023, in Exhibit Halls B-D. The data demonstrate that RAYALDEE effectively and reliably raises serum levels of 25-hydroxyvitamin D (25D) and 1,25-dihydroxyvitamin D in non-dialysis patients with secondary hyperparathyroidism (SHPT), making it an attractive alternative to vitamin D hormone therapies (i.e., calcitriol, paricalcitol and doxercalciferol).

The other poster, “Extended-Release Calcifediol: A Data Journey from Phase 3 Studies to Real-World Evidence Highlights the Importance of Early Treatment of Secondary Hyperparathyroidism” (#FR-PO972), will be presented in the “CKD Interventions: Trials and Quality Improvement” session at 10:00 a.m. Eastern time on Friday, November 3, 2023 in Exhibit Halls B-D. The data demonstrate that effective control of SHPT has been achieved with RAYALDEE treatment in both randomized clinical trials and in a real-world clinical experience trial. Data from these trials support early initiation of SHPT treatment with RAYALDEE in order to delay disease progression.
