Effects of Ergocalciferol on Erythropoetin Stimulating Agent Dose

An interventional study of Ergocalciferol supplementation in Chronic Kidney Disease Stages 3-5, sponsored by Kaiser Permanente. Terminated at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2015-03-30.

Sponsored by Kaiser Permanente · Not applicable, Interventional, and Treatment

Why this study was terminated
Strong enrollment efforts resulted in few eligible subjects and high screen failures due to CKD patients with higher vitamin D levels than anticipated.

Study summary

Hypothesis: The supplementation of Ergocalciferol (Vitamin D2) to those with Vitamin D deficiency in the Chronic Kidney Disease population requiring recombinant human erythropoietin for the treatment of anemia related to kidney disease will reduce the dose of erythropoietin required to maintain a nonanemic state.

Interventions

  • DrugErgocalciferol supplementation

    Vitamin D in the form of ergocalciferol will be the drug utilized in the study. This medication is a Vitamin D analog and is normally used in the current study population to help augment those who are deficient in Vitamin D.
