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 ...
Detailed Description
High levels of phosphate in the blood are linked with serious effects, due to calcium imbalances (high levels of parathyroid hormone (PTH), bone disease, formation of calcium deposites in the body and...
Eligibility Criteria
Inclusion
- Subjects will be considered eligible for entry in the study if they meet all of the following criteria.
- Male or female, aged \> 18 years.
- Able to comply with the study procedures and medication.
- Written informed consent given.

- (a) Subject receiving phosphate binder medication(s) at screening, must have been on a stable regimen (dose and medication) for at least 1 month prior to screening and will remain on this regimen until entry into the washout period OR (b)Subject (i) is not currently receiving any phosphate binding medication at screening (or medication likely to act as a phosphate binder) and (ii) must not have done so for at least one month and (iii) has sustained hyperphosphataemia.
- Willing to abstain from taking any phosphate binder or oral magnesium-, oral aluminium- 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.
- Specifically, for randomisation and inclusion into the treatment period, the following criterion must be fulfilled:
- Has a serum phosphate value of ≥1.94 mmol/L (≥6.0 mg/dL) within the 2 to 4 week washout period or above 3.0 mmol/L (9.3 mg/dL) at any time during washout.
Exclusion
- Subjects will not be considered eligible for entry in the study if they meet one or more of the following criteria.

- Previous experience of fermagate treatment.
- A significant history of alcohol, drug or solvent abuse in the opinion of the investigator.
- Any disease or condition, physical or psychological that, in the opinion of the investigator, would compromise the safety of the subject or the likelihood of achieving reliable results or increase the likelihood of the subject being withdrawn.

- A screen serum magnesium concentration of \>1.25 mmol/L (\>3.0 mg/dL).
- A known history of haemochromatosis.
- Subjects receiving either tetracycline or lithium treatment.
- A serum ferritin level of ≥1000 ng/mL.
- Non-elective hospitalisation in the 4 weeks prior to screening.
- Female subjects who are of childbearing potential and who are neither surgically sterilised nor using reliable contraceptive methods (hormonal, barrier methods or intrauterine device) or who are lactating or pregnant.
- Current hypophosphataemia at screening (last 2 consecutive phosphate values of \<0.7 mmol/L \[\<2.2 mg/dL\]).
- Known history of colorectal malignancy, familial polyposis coli and/or strong family history (in 2 or more first degree relatives) of these terms.
- A QTcF interval of \>560 ms at screen.
- Known persistent (\>1 month) non compliance (\<70%) with prescribed medication regimens at screen.
- Current clinically significant intestinal motility disorder.
- Bowel obstruction with current or previous use of sevelamer HCl.
- Known intolerance to sevelamer HCl or any excipients of fermagate or Renagel medication.
- Subjects with inflammatory bowel disease that, in the investigator's opinion, is poorly controlled.
