Treatment of Hemochromatosis
NCT00007150 · View on ClinicalTrials.gov ↗
Study Summary
This study will evaluate the effectiveness of a test called MCV in guiding phlebotomy (blood drawing) therapy in patients with hemochromatosis an inherited disorder that causes too much iron to be absorbed by the intestine. The excess damages body tissues, most severely in the liver, heart, pancreas and joints. Because iron is carried in the hemoglobin of red blood cells, removing blood can effectively lower the body s iron stores. Patients with hemochromatosis undergo weekly phlebotomy treatments (1 pint per session) to deplete iron stores. This usually requires 10 to 50 treatments, after which blood is drawn every 8 to 12 weeks to prevent a re-build up of iron. A test that measures ferritin a protein involved in storing iron is commonly used to guide phlebotomy therapy in hemochromatosis patients. This study will compare the usefulness of the ferritin test with that of MCV, which measures red blood cell size, in guiding phlebotomy therapy. In addition, the study will 1) examine whether keeping iron levels low during maintenance therapy can help heal severe liver disease and improve arthritis in affected patients, and 2) design a system for making blood collected from hemochromatosis donors available for transfusion into other patients. Patients 15 years and older with diagnosed hemochromatosis or very high iron levels suggesting possible hemochromatosis may be eligible for this study. Candidates will have a history, physical evaluation, review of medical records and blood tests, and complete a symptoms questionnaire. Participants will have the following procedures: * Phlebotomy therapy every 1 to 2 weeks, depending on iron levels * Blood sample collection for blood cell counts and iron studies at every phlebotomy session * Blood sample collection (about 2 tablespoons) every 1 to 2 weeks after iron stores have been depleted * Phlebotomy every 8 to 12 weeks after iron stores are used up to prevent re-build up of excess iron With each blood donation that will be

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00007150
The ClinicalTrials.gov registry entry for NCT00007150 describes a study currently listed as active not recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 622 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institutes of Health Clinical Center (CC), which has 209 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Hemochromatosis appearing as the primary indexed condition, and to 1 intervention — of which Phlebotomy is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00007150 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
