Trial summary

The purpose of this study is to determine the effects of transfusion of fresh and stored blood on patients. The investigators hope to test: whether a similar effect (older stored blood is associated with worse outcomes) is seen in chronically transfused patients with hemoglobinopathies.

About this study

Official title: Harmful Effects of Transfusion of Older Stored Red Cells: Iron and Inflammation

The purpose of this study is to determine the effects of transfusion of fresh and stored blood on patients.

The investigators hope to test:

  • whether a similar effect (older stored blood is associated with worse outcomes) is seen in chronically transfused patients with hemoglobinopathies. This patient population will also allow the investigators to test whether iron- chelation therapy is beneficial in this setting.
  • whether washing or cryopreserving the red blood cells has any effect on this outcome.

These findings may explain the immunomodulatory effects of older stored blood in patients and will help us develop safer transfusion products for patients.

Read the detailed description

Epidemiologic studies suggest that older stored blood is associated with worse outcomes in certain hospitalized patients. Storage of red cells is associated with a storage lesion and the survival of transfused red cells decreases with increasing storage time, thus older blood is associated with an increased acute delivery of hemoglobin-iron to the reticuloendothelial system. The investigators have preliminary data in healthy human volunteers suggesting that delivery of a significant iron load to the reticuloendothelial system from aged red cells leads to the elaboration of a potentially toxic form of iron known as non-transferrin-bound iron.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TransfusionProcedure or surgery

    Also called RBC transfusion

    A routine medical procedure to transfuse packed red blood cells.

  • BloodBiological

    Also called RBC product, Reb Blood Cells

    Processing of RBC for transfusion include the following:

    • Fresh
    • Stored
    • Washed
    • Frozen (Cryopreserved)
  • Chelation therapyProcedure or surgery

    (non-experimental) A medical procedure that involves the administration of chelating agents to remove heavy metals from the body.

Questions about this trial

What is this clinical trial studying?

A study testing Transfusion, Blood and Chelation therapy in people with Sickle Cell Disease and Thalassemia, run by Columbia University at 1 site in United States.

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 11 inclusion and 9 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: stopped early, as of the sponsor's last update on 5 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 United States. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Oct 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Non-transferrin-bound Iron Level (time frame: 2 hours after transfusion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 5 Oct 2016.
