Efficacy and Safety of Vamifeport in Adult Participants With Homeostatic Iron Regulator Gene (HFE)-Related Hereditary Hemochromatosis

Purpose

This is a phase 2, multicenter, randomized, placebo-controlled, double-blind, parallel-group, proof-of-concept study to assess vamifeport in adult participants with homeostatic iron regulator gene-related hereditary hemochromatosis (HFE-HH). The primary objective of the study is to assess the effect of vamifeport treatment on magnetic resonance imaging (MRI)-based liver iron concentration (LIC) in adult participants with HFE-HH.
