Phlebotomy for Iron Overload
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if a test called MCV, which measures red blood cell size, is more effective than the usual ferritin test for guiding phlebotomy therapy in individuals with hemochromatosis. Hemochromatosis causes excessive iron accumulation in the body, potentially damaging organs like the liver and heart. Participants will undergo regular blood removal sessions to reduce iron levels and may contribute to blood transfusions. The study seeks individuals aged 15 and older who have been diagnosed with hemochromatosis or have very high iron levels suggesting this condition. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that phlebotomy is safe for patients with hemochromatosis?
Research has shown that drawing blood, known as phlebotomy, safely and effectively manages high iron levels in people with hemochromatosis. Studies have found that regular blood draws lower the amount of iron in the body. This is crucial because excess iron can damage organs like the liver, heart, and pancreas.
Phlebotomy is also safe and practical for treating iron overload from other conditions. Patients generally tolerate the treatment well, and it can prevent problems caused by excess iron. Starting regular phlebotomy early in hereditary hemochromatosis can even restore normal life expectancy.
Overall, while the process involves frequent blood draws, the benefits of reducing iron levels make it a well-tolerated and effective treatment for managing iron overload.12345Why are researchers excited about this trial?
Phlebotomy is unique because it directly removes excess iron from the body by drawing blood, which is a straightforward and natural way to manage iron overload in conditions like hereditary hemochromatosis (HH). Unlike other treatments that may involve medication to bind and eliminate iron, phlebotomy works by reducing the iron stores more directly and naturally. Researchers are excited about this treatment because it is a non-invasive procedure that can effectively lower iron levels without the need for additional drugs, minimizing potential side effects.
What evidence suggests that this trial's treatments could be effective for hemochromatosis?
Research has shown that drawing blood, known as phlebotomy, effectively treats hemochromatosis. This condition causes excessive iron accumulation in the body, and phlebotomy helps by removing the extra iron from the blood. Studies have found that phlebotomy can correct iron overload and prevent damage to organs like the liver and heart if performed before the damage becomes permanent. In one study, almost all patients successfully reduced their iron levels, demonstrating the treatment's effectiveness. Another study found that other treatments, such as medicines that bind to iron, were less effective than phlebotomy.45678

Are You a Good Fit for This Trial?
This trial is for individuals aged 15 or older with diagnosed hemochromatosis, a condition where too much iron is absorbed by the body. It's also open to those with high iron levels suggesting hemochromatosis, and family members being screened for it. People can't join if they're under 15, need phlebotomy for other conditions like polycythemia vera, have certain illnesses that increase risk, are pregnant, or have iron overload not caused by hemochromatosis.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Initial Phlebotomy Treatment
Participants undergo weekly phlebotomy treatments to deplete iron stores, requiring 10 to 50 treatments
Maintenance Phlebotomy
Blood is drawn every 8 to 12 weeks to prevent re-build up of iron
Follow-up
Participants are monitored for safety and effectiveness after treatment, including evaluation of liver and arthritis symptoms
What Are the Treatments Tested in This Trial?
Interventions
- Phlebotomy
Trial Overview
The study tests whether MCV (a measure of red blood cell size) can guide phlebotomy therapy as effectively as the ferritin test in patients with hemochromatosis. Participants will undergo regular blood drawing sessions to manage their iron levels and may contribute blood for transfusions. Some may be evaluated further for liver disease or arthritis linked to their condition.
