Effects of Ergocalciferol on Erythropoetin Stimulating Agent Dose (EASY)

This study has been terminated.
(Strong enrollment efforts resulted in few eligible subjects and high screen failures due to CKD patients with higher vitamin D levels than anticipated.)

Information provided by (Responsible Party):
Kaiser Permanente
  Purpose
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.

Condition Intervention
Chronic Kidney Disease Stages 3-5 Drug: Ergocalciferol supplementation

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Effects of Ergocalciferol on Erythropoetin Stimulating Agent Dose

Primary Outcome Measures:
  • Evaluate if Ergocalciferol Supplementation to Achieve 25-hydroxy Vitamin D Levels > 40ng/ml Will Decrease Erythropoietin Requirements [ Time Frame: 24 Weeks ]

Secondary Outcome Measures:
  • Change in Inflammatory Markers [ Time Frame: 24 Weeks ]
  • Change in Calcium, Phosphorous,Calcium x Phosphorous Product, and Parathyroid Hormone Levels [ Time Frame: 24 Weeks ]
  • Change in Iron Supplementation [ Time Frame: 24 Weeks ]
  • Change in Erythropoietin Adjusted for Change in Inflammatory Markers, Vitamin D Levels and Clinical and Demographic Confounders [ Time Frame: 24 Weeks ]

Enrollment: 6
Study Start Date: August 2010
Study Completion Date: September 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ergocalciferol supplementation Drug: Ergocalciferol 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.
