Hepcidin deficiency in hereditary hemochromatosis (HH) leads to increased absorption of dietary iron and thus iron overload. Rusfertide is a hepcidin mimetic peptide that has shown efficacy at reducing the need for therapeutic maintenance phlebotomy in patients with HH. Researchers aimed to evaluate the benefits of cotreatment with a hepcidin mimetic peptide plus the rusfertide analogue PN-23114 (Protagonist Therapeutics Inc.) at 7.5 mg/kg t.i.w. and phlebotomy in a murine model of HH.
