Filter by:The purpose of the study is to learn more about how treatment with vitamin D can affect iron metabolism and blood levels of two hormones that control iron levels, hepcidin and hemojuvelin in people with chronic kidney disease (CKD). Iron is an essential mineral which is a major component of proteins that carry oxygen in the blood. Problems with iron metabolism can lead to low blood levels (anemia), which can commonly happen in people with CKD. New research over the last decade has uncovered a new hormone called `hepcidin', which is made in the liver and released into the blood. Hepcidin controls how much iron is in the blood by preventing the absorption of iron from food. Blood levels of hepcidin C are found to be high in people with CKD, and a recent small study in people with normal kidney function showed that treatment with vitamin D decreased hepcidin levels. Another protein, known as `hemojuvelin', has been recently discovered and is also thought to control the amount of iron in the blood. The relationship between vitamin D and hemojuvelin has never been studied before. In this study, investigators would like to examine the effects of vitamin D on iron metabolism and blood levels of hepcidin C and hemojuvelin in individuals with CKD.
This study is conducted to determine the safety, tolerability, and efficacy of NOX-H94 in patients with anemia of chronic disease (ACD). Furthermore, this study is intended to provide data needed to correlate plasma concentrations of NOX-H94 with its efficacy and to choose the appropriate dose and dose schedule of subsequent efficacy studies. Some chronic diseases, e.g. tumors, inflammation, renal disease, are associated with high hepcidin concentrations in the blood. These hepcidin concentrations cause a reduction in iron concentrations in the blood and subsequently impair formation of red blood cells. Treatment with NOX-H94 is expected to inhibit this patho-mechanism by binding and inactivating hepcidin.
The purpose of this study is to assess the effect of the anti-hepcidin Spiegelmer NOX-H94 on iron homeostasis during systemic inflammation induced by endotoxin. In the human endotoxemia model, intravenously administered lipopolysaccharide elicits an inflammatory response with release of pro-inflammatory cytokines, such as IL-6 and TNF-alfa, with subsequent induction of hepcidin. As a consequence of hepcidin induction, serum iron concentrations decrease. This study in healthy subjects investigates the capacity of NOX-H94 to inactivate hepcidin and to prevent serum iron decrease in a pathophysiological model prior to studying the efficacy of NOX-H94 in patients with anemia of chronic disease.
