Trial summary
Cardiopulmonary bypass and arrest of the heart during cardiac surgery are necessary to allow the surgeon to perform heart operations. However, these processes can cause injury to the heart which may worsen post-operative outcomes. Read more about this study

About this study
Cardiopulmonary bypass and arrest of the heart during cardiac surgery are necessary to allow the surgeon to perform heart operations. However, these processes can cause injury to the heart which may worsen post-operative outcomes. In fact, the effects of these injuries may continue after surgery, and lead to a long-term decrease in heart function. Neonates and young infants are at particular risk for this occurrence.
While much research has been done in adults looking for medicines that might protect the heart during surgery, few studies have been conducted in neonates and young infants. The investigators are testing Dexrazoxane, which has proven to be cardio-protective in pediatric cancer patients, in the hope that it may lessen cardiac injury during and after congenital heart surgery, and thereby improve outcomes in the neonatal and young infant population.

In order to accomplish this, the investigators must first determine how Dexrazoxane can be safely administered to young children with congenital heart disease. Therefore, the investigators are performing a pilot study of 12 children to assess:
- how Dexrazoxane at 3 different doses is metabolized in the body of a child age 0-6 months during and after congenital heart surgery, and
- the safety of Dexrazoxane use in the neonatal and young infant population undergoing cardiac surgery.
Read the detailed description
Neonates and infants undergoing heart surgery with cardioplegic arrest experience both inflammation and myocardial ischemia-reperfusion [IR] injury. These processes provoke myocardial apoptosis and oxygen free radical formation which result in cardiac injury and dysfunction. Dexrazoxane is a derivative of EDTA that is approved for prevention of anthracycline-related cardiotoxicity. It provides cardioprotection through reduction of toxic reactive oxygen species [ROS], and suppression of apoptosis.
The deleterious effects of cardiopulmonary bypass [CPB] with cardioplegic arrest of the heart during congenital heart operations greatly influence postoperative morbidity and mortality. Neonates and infants undergoing cardiac surgery experience both a systemic inflammatory response, and myocardial IR injury as cardioplegic arrest is reversed. These processes provoke elaboration of cytokines and activation of the complement cascade, as well as oxygen free radical formation and induction of myocardial apoptosis (1, 2, 3). Frequently, myocardial injury and cardiac dysfunction ensue, leading to low cardiac output syndrome and multi-system organ failure. The irreversible component of these injuries, in addition to the abnormal workloads imposed on the myocardium from the anatomic defects themselves, may have consequences for long-term cardiac function, and may in part explain contractile dysfunction observed late after congenital heart
The investigators propose a pilot pharmacokinetic/safety trial of dexrazoxane in children 0-6 months of age, followed by a randomized, double-blind, clinical trial of dexrazoxane vs placebo during congenital heart surgery. The investigators will evaluate postoperative time to resolution of organ failure, development of low cardiac output syndrome, length of cardiac ICU and hospital stays, and echocardiographic indices of cardiac dysfunction. Results could establish the safety and clinical utility of dexrazoxane in ameliorating ischemia-reperfusion injury during congenital heart surgery.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Dexrazoxane in people with Heart Defects, Congenital, run by Medical City Children's Hospital 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 3 inclusion and 5 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 26 Jul 2018. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 was stopped early (reason given: PI no longer at this facility). Results are not available in the source record.
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?
Resolution of organ failure (time frame: 60 days postoperative). 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 NCT02519335, which also lists 36 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 26 Jul 2018.
