Trial summary

Anemia is a common disorder in infants with one working chamber of the heart that pumps blood. Anemia is when the level of healthy blood cells becomes too low. This may cause other health problems because red blood cells contain hemoglobin, which carries oxygen (needed for survival) to different parts of the body. Read more about this study

About this study

Official title: Iron Prophylaxis for Anemia in Infants With Cyanotic Congenital Heart Disease: An Open Label Trial

Anemia is a common disorder in infants with one working chamber of the heart that pumps blood. Anemia is when the level of healthy blood cells becomes too low. This may cause other health problems because red blood cells contain hemoglobin, which carries oxygen (needed for survival) to different parts of the body.

This study will look at the role of iron in preventing anemia in infants with one pumping chamber. The importance of iron therapy will be examined.

Hypothesis: Prophylactic use of iron in infants with single ventricle is effective in preventing anemia.

Read the detailed description

At the beginning of the study, subjects will be randomized to two different groups. One group will receive iron every day for the next 4 months or so (up until their Glenn surgery); the other group will not receive any iron. Those in the iron treatment arm of the study will receive iron education at discharge from their first stage surgery (Norwood or BTS surgery) and will be given vials of iron to take home. A patient will receive a set amount of iron (dose will be 3 mg/kg) once a day. Weekly follow-up phone calls will be conducted by study personnel to re-calculate dose of iron for parents (based on weight) as well as check on the status of the research subject.

Group II will not receive iron but will be a participant in the study and follow the course of the non-iron randomized patients.

Blood samples will also be drawn at the same time as standard of care labs at two time points during the course of the study for both groups of patients. Blood for iron study labs will be drawn at 72 hours prior to discharge from the first stage surgery and at the pre-Glenn screening. A reticulocyte count test will also be done at the pre-Glenn screening. These lab tests look at the number of red blood cells in the body, the type of red blood cells, their ability to carry oxygen and the iron status of the research subject. Additionally, data will be collected on the CBC count, subject's age, weight, pulse oximetry, surgical history, transfusion history, iron levels and therapy, and hematological indices (Hgb, Hct, MCV, RDW, RBC count, and reticulocyte count), as well as peripheral blood smear. Feeding history will be carefully documented. Descriptive demographic data and underlying diagnosis will be collected, along with all the above variables defined.

The hemoglobin and iron levels at the time of pre-Glenn labs will be compared to those at the start of the study. The importance of iron therapy will be examined.

Iron is a readily available medicine for both the prevention and treatment of anemia. If this simple cost-effective medicine can decrease the prevalence of anemia in these infants, it may result in more oxygen to the body's tissues and areas, less stress on the single pumping chamber of the heart and it may also improve their overall growth and development.

  1. Primary Aim - To achieve a higher hemoglobin level at time of second stage surgery (Glenn procedure).
  2. Secondary Aims - To obtain the following outcomes:
  3. Increased ferritin levels
  4. Decreased interval blood transfusions
  5. Normal MCV (red cell volume) and RDW (red cell distribution)

What participants receive

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

  • Iron (ferrous sulfate)Drug

    The subjects in the iron treatment arm of the study will receive 3 mg/kg of oral/enteral iron solution once a day beginning at the time of discharge until the pre-Glenn screening which is the endpoint of the study. The iron will be dispensed for the subjects upon discharge from the hospital. The subjects randomized to the no iron treatment arm and the patients in Group II of the study will not receive iron upon discharge. However, they may be started on iron therapy in an intent-to-treat anemia by their primary physician in which case this will serve as the endpoint of the study for these participants.

Study groups in NCT00459225
Study groupRoleWhat they receive
1Active comparatorThe parent/guardian will be educated on the iron study and provided the opportunity to ask questions. If the parent/guardian chooses to participate in the study, the parent/guardian will give informed consent for the patient to be placed in either Group I or Group II, based upon guardian/parents' choice for participation in the iron arm of the study. Group I will be randomized in a 1:1 ratio in this open label trial to either receive or not receive iron. Group II will not receive iron but will be a participant in the study and follow the course of the non-iron randomized patients.

2No interventionGroup II will not receive iron but will be a participant in the study and follow the course of the non-iron randomized patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Complete blood count, Iron study labs (ferritin, Total Iron Binding Capacity, and Iron lab) 72 hours prior to discharge following neonatal surgery

    Measured: Discharge from hospital

  2. Hemoglobin and Hematocrit at pre-Glenn catheterization

    Measured: Will be assessed at the pre-Genn catheterization

  3. Complete Blood count, Iron study labs, and Reticulocyte count at pre-glenn screening

    Measured: Will be assessed at the pre-glenn screening

Secondary outcomes (1)
  1. feeding regimen and transfusion history at 72 hours prior to discharge from neonatal surgery, at pre-Glenn catheterization, and at pre-Glenn screening

    Measured: Will be assessed at the time of discharge, pre-Glenn catheterization and screening.

The record says: withdrawn, as of the sponsor's last update on 9 Dec 2014. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Complete blood count, Iron study labs (ferritin, Total Iron Binding Capacity, and Iron lab) 72 hours prior to discharge following neonatal surgery (time frame: Discharge from hospital). The study lists 3 primary outcomes in all. 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 NCT00459225, which also lists 5 linked publications.
