  Purpose

The aim of the study is to assess the effects of the drug lanthanum carbonate (a phosphorus binder drug) on c-terminal and on FGF23 levels in patients with Chronic Kidney Disease (CKD).

Targeting FGF23 measurement in CKD patients may impact both the progression of kidney disease and patient mortality.

Detailed Description:

This is a double blind randomized placebo controlled pilot study. Subjects with Chronic Kidney Disease ( CKD) stages 3-5 who are not undergoing renal replacement therapy and have not been started on phosphate binders will be randomized to either lanthanum carbonate 1500 mg daily or placebo for a 60 day treatment period. Patient doses will be increased up to a maximum dose of 3000 mg if the serum phosphate is greater than 5.5 mg/dL.
