Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Iron deficiency is common and when oral treatment is not sufficient intravenous application is indicated. Hypersensitivity to intravenous iron nanomedicines is rare but does occur and little is known about the underlying mechanism but complement activation has been suggested.

This is a purely exploratory study as it is not yet known whether in vitro complement activation can be stimulated by titration with iron preparations. These data will provide first empirical evidence of whether and to what extent complement activation occurs in this population.
