OPK - New Clinical Data on OPKO Health's RAYALDEE® (ER Calcifediol) Presented at Kidney Week 2023 | Benzinga
MIAMI, Nov. 02, 2023 (GLOBE NEWSWIRE) -- OPKO Health, Inc. (NASDAQ:OPK) presented late-breaking clinical data on RAYALDEE® extended-release calcifediol (ERC) at the American Society of Nephrology (ASN) Kidney Week in Philadelphia today. These data, presented in a poster titled "Control of Secondary Hyperparathyroidism with Extended-release Calcifediol is Associated with Slower CKD Progression" (#TH-PO1152), indicate that early, sustained and effective treatment of secondary hyperparathyroidism (SHPT) with RAYALDEE is associated with significantly slower progression of chronic kidney disease (CKD) in pre-dialysis patients.
The poster is available on OPKO's website here.
Progressive changes in estimated glomerular filtration rate (eGFR) were examined post-hoc in 166 patients with vitamin D insufficiency, SHPT and stage 3 or 4 CKD during one year of treatment with RAYALDEE in pivotal trials. The average eGFR decline was 7.7% per year but differed significantly and proportionately with the achieved duration of intact parathyroid hormone (iPTH) control, defined as ?100 pg/mL, being greatest (16.4%) in patients who never achieved control and least (1.7%) in those achieving consistent control. The number of patients experiencing an increase in eGFR by the end of treatment rose from 3.6% to 10.8% as the duration of iPTH control increased. Treatment with RAYALDEE was not associated with clinically meaningful increases in serum calcium or phosphorus.
