A Phase 4 interventional study of cinacalcet in Chronic Kidney Disease, End Stage Renal Disease and Coronary Artery Calcification, sponsored by Amgen. Completed. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2014-07-23.
Sponsored by Amgen · Phase 4, Interventional, and Treatment
The purpose of this study is to evaluate whether cinacalcet + low dose vitamin D attenuates the progression of vascular calcification over one year, compared with a treatment regimen that includes flexible vitamin D dosing in the absence of cinacalcet, in subjects with chronic kidney disease receiving hemodialysis
