NCT00841126

Brief Summary

Magnesium iron hydroxycarbonate is a phosphate binder that absorbs phosphate from food, reducing the amount that the body can absorb. The purpose of this study is to assess the efficacy of magnesium iron hydroxycarbonate in subjects requiring hemodialysis, compared with a marketed phosphate binder, lanthanum carbonate and placebo.

  • Willing to abstain from taking any phosphate binder or oral magnesium-, oral aluminum- or oral iron-containing products and preparations other than the study medication.
  • If required to take \>6000 mg/day of fermagate, the subject will be willing to have at least three meals per day.
  • (a) Is not receiving phosphate binding medication at screen and has a screen serum phosphate value above 3.0 mmol/L (9.3 mg/dL)OR(b) Has a serum phosphate value of ≥1.94 mmol/L (≥6.0 mg/dL) at Washout Visit 2 to 4 or above 3.0 mmol/L (9.3 mg/dL) at visit 1 during washout.
