Deferoxamine for the Treatment of Hemochromatosis

United States151 participantsStarted 1985-04-22

Plain-language summary

When patients receive repeated blood transfusions the level of iron in the patient s blood can rise. When iron is processed in the body a protein known as hemosiderin can begin collecting in the organs. If too much hemosiderin collects in the organs they can begin to malfunction. This condition is called transfusional hemochromatosis. An organ of particular importance in transfusional hemochromatosis is the heart. Patients born with diseases requiring blood transfusions at birth begin to develop heart problems in their teens. These patients typically only live for 17 years. Adults that require transfusions can begin experiencing heart problems after 100-200 units of backed red blood cells. Deferoxamine (Desferal) is a drug that binds to iron and allows it to be excreted from the body. It is the only effective way to remove iron from patients who have been overloaded with iron because of multiple transfusions. Previous studies have lead researchers to believe that deferoxamine, when given as an injection under the skin (subcutaneous), can be delay or prevent heart complications. Researchers plan to continue studying patients receiving deferoxamine as treatment for the prevention of heart complications associated with repeated blood transfusions. In this study researchers will attempt; 1. To determine if deferoxamine, given regularly, can indefinitely prevent the heart, liver, and endocrine complications associated with transfusional hemochromatosis 2. To determine whether heart disease caused by transfusional hemochromatosis can be reversed by intensive treatment with deferoxamine.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

* INCLUSION CRITERIA Patients studied under this protocol will be at risk for or have evidence of significant excess tissue iron. Most patients will be on regular blood transfusion secondary to either congenital or acquired anemia. The majority of patients have homozygous beta thalassemia. Patients with sickle cell anemia will be included only when there is an absolute indication for regular blood transfusions (e.g., a history of stroke). Twenty to thirty adults with acquired anemia and good long-term prognosis will be accepted for study if chelation can be initiated early in their transfusion history (less than 30-50 units). EXCLUSION CRITERIA Such patients will be excluded from study if they have diabetes or cardiac disease due to another cause (coronary artery or valvular heart disease).

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.
