Study of Safety and Efficacy of Doxercalciferol in Patients With Chronic Kidney Disease, Stage 3 or 4, and Secondary Hyperparathyroidism - Full Text View

Sponsor:	Genzyme
Information provided by:	Genzyme
ClinicalTrials.gov Identifier:	NCT00123461

Purpose

The purpose of this study is to demonstrate the safety and effectiveness of Hectorol® (doxercalciferol) capsules in treating patients with Stage 3 or Stage 4 chronic kidney disease (CKD) with secondary hyperparathyroidism who have vitamin D levels in the normal range. Previous studies with doxercalciferol were conducted in patients who had low levels of vitamin D.

Condition	Intervention	Phase
Secondary Hyperparathyroidism Renal Failure Chronic Renal Insufficiency	Drug: Hectorol (doxercalciferol capsules), 0.5mcg	Phase IV

Study Type:	Interventional
Study Design:	Treatment, Randomized, Double-Blind, Placebo Control, Parallel Assignment, Safety/Efficacy Study
Official Title:	A Phase 4, Multi-center, Randomized, Double-blind, Placebo-controlled, Parallel Study to Assess the Efficacy and Safety of Doxercalciferol Capsules in Vitamin D-replete Subjects With Chronic Kidney Disease (CKD) Stages 3 or 4 With Secondary Hyperparathyroidism (SHPT).
