Multi-Center Study of Iron Overload: Pilot Study
United States, Germany, United Kingdom20 participantsStarted 2009-11-01
Plain-language summary
The purpose of this study is to initiate pilot studies to demonstrate that a sufficient number of iron-overloaded thalassemia, SCD and DBA populations with similar duration of chronic transfusion, and age at start of transfusions would be available for a confirmatory study and to validate that proposed multicenter MRI and biochemical studies can be completed. The study will examine the hypothesis that a chronic inflammatory state in Sickle Cell Disease (SCD) leads to hepcidin- and cytokine-mediated iron withholding within the RES (reticuloendothelial system), lower plasma NTBI (non transferrin bound iron) levels, less distribution of iron to the heart in SCD.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* 10-20 years of transfusion (defined as 0.2-0.6mg Fe/kg/day exposure with annual ferritin levels greater than 2500 in at least 60% of years of chronic transfusion);
* 0 to 9 years old at the initiation of chronic transfusions; no exchange transfusions in the previous 6 months
* iron overload documented by either liver biopsy, MRI or SQUID with estimated LIC of greater than 7 mg/g dry wt in the previous 6 months or ferritin level greater than 1500mg/dl.
Exclusion Criteria:
* Patients with HbSC, HbS/β thalassemia
* Pacemaker (active or inactive) or other implanted magnetic devices, severe claustrophobia, or other contraindications to MRI; Unable to remove ferro-magnetic objects from the body in regions to be imaged (e.g., jewelry or piercing)
* Presence of any other condition which, in the opinion of the investigator, would make the patient unsuitable for enrollment;
* Any chronic inflammatory illness other than the SCD, TM or DBA;
* Any acute illness within a 14 day period prior to blood sampling;
* Patients receiving intensive chelation in the 6 months prior to enrollment including deferoxamine 24 hours per day, 7 days per week or combination treatment with 2 chelators
* Pregnancy
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.
