Purpose of this Study
In this study, people will take capsules that contain either the study drug, called vamifeport, or a placebo, which looks the same but has no medicine. The study lasts about fourteen months and has around fifteen in person visits. At these visits, people will have blood tests, heart tests called ECGs, MRI scans, and questionnaires.
If someone gets vamifeport, they will take it twice a day in one of two dose groups. One group takes 90 milligrams twice a day, which is one capsule in the morning and one in the evening. The other group takes 270 milligrams twice a day, which is three capsules in the morning and three in the evening. If someone gets a placebo, they will also take either one capsule twice a day or three capsules twice a day, depending on their group.

What is Involved?
Description
This study is being done to find out if a pill called vamifeport is safe and helps people who have hereditary hemochromatosis. This condition causes the body to absorb too much iron. The study will compare vamifeport to a placebo, which looks like the medicine but has no drug in it, to see which works better.
