Phase III Study to Investigate the Safety and Efficacy of Fermagate and Lanthanum Carbonate

2014-08-27 03:24:26 | BioPortfolio

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.

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 blood-vessel disease.

Current guidelines indicate that blood phosphorous levels should be maintained between 1.13 to 1.78 mmol/L in patients who receive hemodialysis.

This is a 2-stage re-randomization design where Stage 1 is a randomized, open label comparison between fermagate and lanthanum carbonate (in a non-inferiority design) and Stage 2 is a randomized double blind comparison between fermagate and placebo (in a superiority design).

Objectives at Stage 1:

Primary Objective:

The primary objective is to establish the efficacy of fermagate by demonstrating the noninferiority (with possible assessment of superiority) of fermagate to lanthanum carbonate in lowering serum phosphate in hemodialysis patients.

Secondary objectives:

The secondary objectives are to:

1. Determine the safety of fermagate in hemodialysis patients.

2. Compare the effects of fermagate and lanthanum carbonate on measures of mineral metabolism, albumin, pre-albumin and iron status.

Objectives at Stage 2:

Stage 2 will use patients who complete the 3-month maintenance period of Stage 1 and who were originally randomized to fermagate.

Primary Objective:

The primary objective is to establish efficacy of fermagate by demonstrating the superiority of fermagate over placebo in lowering serum phosphate in hemodialysis patients.

Secondary objectives:

The secondary objectives are to:

1. Determine the safety of fermagate in hemodialysis patients.

2. Compare the effects of fermagate and placebo on measures of mineral metabolism, albumin, pre-albumin and iron status.

Medical and Biotech [MESH] Definitions

Lanthanum. The prototypical element in the rare earth family of metals. It has the atomic symbol La, atomic number 57, and atomic weight 138.91. Lanthanide ion is used in experimental biology as a calcium antagonist; lanthanum oxide improves the optical properties of glass.

The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.

A group of iron-binding proteins that tightly bind two ferrate ions along with two carbonate ions. They are found in the bodily fluids of vertebrates where they act as transport and storage molecules for iron.

Conditions in which the KIDNEYS perform below the normal level for more than three months. Chronic kidney insufficiency is classified by five stages according to the decline in GLOMERULAR FILTRATION RATE and the degree of kidney damage (as measured by the level of PROTEINURIA). The most severe form is the end-stage renal disease (CHRONIC KIDNEY FAILURE). (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002)

An excessive accumulation of iron in the body due to a greater than normal absorption of iron from the gastrointestinal tract or from parenteral injection. This may arise from idiopathic hemochromatosis, excessive iron intake, chronic alcoholism, certain types of refractory anemia, or transfusional hemosiderosis. (From Churchill's Illustrated Medical Dictionary, 1989)
