United States, Australia, Austria84 participantsStarted 2026-01-22
Plain-language summary
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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult (≥ 18 years) and has provided written informed consent.
* Confirmed diagnosis of HFE-HH in medical history.
* Evidence of iron overload as shown by:
* TSAT \> 45% (confirmed at 2 visits, at least 14 days apart) at Screening; and
* Serum ferritin ≥ 200 nanogram per milliliter (ng/mL) and \< 5000 ng/mL (confirmed at 2 visits, at least 14 days apart) at Screening; and
* MRI-based LIC between 3 and 16 mg/g (53.7 and 286.5 millimol per kilogram \[mmol/kg\]) dry weight (dw) at Screening.
* Body mass index between 18.5 and 32 kilograms per meter squared (kg/m\^2).
Exclusion Criteria:
* Clinically relevant laboratory abnormalities, 12-lead electrocardiogram (ECG) findings, or medical history.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
