NCT01220843

Brief Summary

The purpose of this study is to evaluate in Chronic Kidney Disease (CKD) patients not on dialysis and who have an Fibroblast growth factor 23 (FGF23) serum levels elevated, the effect of non calcic phosphate binder: sevelamer carbonate. This treatment could lead to a diminution of FGF23 serum levels due to the diminution of intestinal absorption of dietary phosphate. In addition, the investigators will describe the impact of the FGF23 level monitoring on the main phosphocalcium metabolism markers as phosphatemia, intact parathyroid hormone (iPTH), serum calcitriol and phosphaturia.

Outcome Measures

Primary Outcomes (1)

  • Measurement of the serum levels of C terminal segment of fibroblast growth factor 23 (FGF23) and evaluation of sevelamer carbonate effect on this levels in comparison with placebo

    Indeed the sevelamer carbonate could lead to a diminution of FGF23 serum levels due to the diminution of intestinal absorption of dietary phosphate.

    12 weeks after the beginning of treatment

Secondary Outcomes (8)

  • Evaluation of sevelamer carbonate effect on the serum levels of iPTH

    12 weeks after the beginning of treatment

  • Evaluation of sevelamer carbonate effect on the serum levels of calcitriol (1 25(OH)2D3)

    12 weeks after the beginning of treatment

  • Evaluation of sevelamer carbonate effect on the serum levels of others mineral metabolism parameters (phosphore, calcium, intact FGF-23 , 25(OH)D3, bone specific alkaline phosphatases, osteocalcin, collagen crosslink, C reactive protein)

    12 weeks after the beginning of treatment

  • Evaluation of sevelamer carbonate effect on the urinary levels of phosphate

    12 weeks after the beginning of treatment

  • Evaluation of sevelamer carbonate effect on the urinary levels of calcium

    12 weeks after the beginning of treatment

  • +3 more secondary outcomes
