About this study

Official title: High Dose Intravenous Iron in Blood Donors With Iron Deficiency: a Randomized, Controlled Trial

2-3% of the population participates in blood donation programmes. Traditionally, safety issues in transfusion medicine have been concentrating on product and recipient safety. Extensive efforts including strict donor inclusion criteria and testing for important transmissible infections have substantially improved product quality. One of the most common risks of blood donation is iatrogenic iron deficiency. It may affect up to 30% of regular blood donors because each whole blood donation causes a loss of 200 to 250 mg of iron. Although this has been known for at least 50 years, iron deficiency is not routinely assessed or treated in this population. Contributing factors include donation frequency, lower weight and female gender. Women have lower iron reserves and in premenopausal women, the daily required amount of iron is higher than in men. Besides anemia, iron deficiency may lead to fatigue and impaired cognitive and physical performance. Oral iron substitution is often associated with significant gastrointestinal side effects leading to poor compliance. Today, intravenous (iv.) iron preparations are well tolerated and allow the application of a large dose of 1000mg in one visit. Our hypothesis is that in blood donors with iron deficiency intravenous iron is feasible and preferable to oral iron because of its high efficacy and optimal compliance with a similar safety profile that has been extensively studied in other populations than blood donors.

Read the detailed description

Iron deficiency is possibly the most prevalent worldwide nutritive deficiency and it has been estimated that > 500 million people have adverse effects as a result. Total body iron amounts to 3 to 4.5 grams, the largest part being bound to hemoglobin in red cells.

One of the most common risks of blood donation is iatrogenic iron deficiency which may affect up to 30% of regular blood donors. Each whole blood donation means a whole blood loss of 450 ml ±10% for the bag and additional samples for the required tests, corresponding to a loss of 200 to 300 mg of iron. It has been estimated that 10 apheresis donations equal 1 whole blood donation. Contributing factors include donation frequency, low body weight and female gender. In Austria, the maximal annual donation frequency is 50x for plasmapheresis, 26x for plateletpheresis and 4 (women) respectively 6x (men) for whole blood donations. Although the frequent donation-induced development of iron depletion has been recognized for at least 50 years, iron deficiency is not routinely assessed or treated in this population. Recently it was reported that the presence of pica, the bizarre consumption of nonnutritive substances such as ice cubes, is associated with a high probability of iron depletion in blood donors.

Contributing factors to a poor iron status in blood donors include donation frequency, lower weight and female gender. Women also have lower iron reserves and in premenopausal women, the daily required amount of iron is higher than in men. Besides anemia, iron deficiency may lead to fatigue and impaired cognitive and physical performance. Several trials have evaluated different regimens of iron substitution in blood donors and demonstrated good treatment compliance and efficacy in improving iron status. Oral iron substitution is often associated with significant gastrointestinal side effects leading to poor compliance. Today, high-dose intravenous (iv.) iron preparations are available, well tolerated and allow for the application of a large dose of 1000mg in one visit.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing ferric carboxymaltose and oral iron in people with Iron Deficiency, run by Medical University of Graz at 1 site in Austria.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

transferrin saturation (%) at visit 1 (V1) (time frame: 8 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01787526, which also lists 12 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2016.
