Efficacy and Safety of Lanthanum Carbonate in Reducing Serum Phosphorus Levels in Subjects With Stage 3 and 4 Chronic Kidney Disease - Full Text View

Sponsor:	Shire Pharmaceutical Development
Information provided by:	Shire Pharmaceutical Development
ClinicalTrials.gov Identifier:	NCT00234702

Purpose

Chronic kidney disease (CKD) can result in a loss of ability to filter and excrete phosphate. The body's attempt to adjust to an increased level of phosphate in the blood can result in elevated levels of hormones and minerals resulting in serious clinical consequences. This study is being conducted to evaluate the safety and efficacy of lanthanum carbonate in lowering high levels of phosphorus in the blood in subjects with CKD Stages 3 and 4 compared to placebo.

Study Type:	Interventional
Study Design:	Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Placebo Control, Parallel Assignment, Safety/Efficacy Study
Official Title:	A Phase II, Double-Blind, Randomized, Placebo-Controlled Study to Assess the Efficacy and Safety of Lanthanum Carbonate for the Reduction of Serum Phosphorus in Subjects With Stage 3 and 4 Chronic Kidney Disease Who Have Elevated Serum Phosphorus Levels
