Pharmacokinetics/Pharmacodynamics of NOX-H94 in the Human Endotoxemia Model

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.

Primary Outcome Measures:
  • serum iron [ Time Frame: 9 hours ]
    Change versus baseline; comparison of subjects treated with NOX-H94 versus placebo

Secondary Outcome Measures:
  • Pharmacodynamics: Effects of NOX-H94 on Iron homeostasis [ Time Frame: up to 2 Weeks ]

    Change from baseline and group comparison (NOX-H94 vs. placebo) of:

    serum iron, transferrin saturation, ferritin

  • Pharmacokinetic profile of NOX-H94 [ Time Frame: 12 time points over 2 Weeks ]
    plasma concentration-time profile T0 to 2 weeks

  • Safety and tolerability [ Time Frame: up to 2 Weeks ]
    Safety and tolerability parameters will be evaluated along the entire study duration consisting of spontaneously reported adverse events, physical examination and vital signs, hematology and clinical chemistry laboratory examinations.

  • Effects of NOX-H94 on innate immune response [ Time Frame: up to 2 weeks ]
    To assess the effect of a single dose administration of NOX H94 on the innate immune response during experimental endotoxemia: TNF-α, IL-6, IL-1RA, IL-10

  • Pharmacokinetics: Cmax of NOX-H94 [ Time Frame: Day 1 ]
  • Pharmacokinetics: AUC of NOX-H94 [ Time Frame: 0-2 weeks ]
  • Pharmacokinetics: Clearance of NOX-H94 [ Time Frame: 0-2 weeks ]
  • Pharmacodynamics: effect of NOX-H94 on Red blood cell parameters [ Time Frame: 0- 2 weeks ]
    Change versus baseline and group comparison: reticulocyte hemoglobin content, hemoglobin, mean cell volume, mean cell hemoglobin
