Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

3. Written informed consent given.
4. On a stable hemodialysis regimen (at least 3x per week) for =12 weeks prior to screening.
5. (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) Subjects (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 hyperphosphatemia.
6. 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.

Specifically, for randomization and inclusion into the treatment period, one of the following criteria must be fulfilled:
8. (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.

Key exclusion criteria
Exclusion:

Subjects will not be considered eligible for entry in the study if they meet one or more of the following criteria.

13. Current hypophosphatemia at screening (last 2 consecutive phosphate values of <2.2 mg/dL [<0.7 mmol/L]).
14. Known history of colorectal malignancy, familial polyposis coli and/or strong family history (in 2 or more first degree relatives) of these terms

20. Subjects with inflammatory bowel disease that, in the investigator's opinion, is poorly controlled.
21. Subjects placed under guardianship or tutelage.
22. Subjects previously withdrawn from the study.

The above inclusion and exclusion criteria would be the same for all countries except the exclusion criteria of the QTc interval would be different for Germany (QTc interval of >470ms at screen).

Summary
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.
