About this study
The purpose of this study is to determine whether children and adolescents 8-18 years of age with HLHS and related lesions who have undergone stage I palliation during infancy using an allograft patch demonstrate continued evidence of HLA antibody formation.
Read the detailed description
This study will be of a prospective cross-sectional design, consisting of three groups. The first two groups (study groups) will consist of (1) subjects with HLHS and other related lesions who have undergone stage I palliation using an allograft patch during infancy and (2) subjects with "single ventricle" lesions who have undergone stage II palliation using allograft without antecedent stage I palliation. The third group (control group) will consist of subjects who have undergone corrective or palliative surgery for CHD during infancy in which an allograft patch was not used, and in which there have been no further exposures to allograft. We have chosen to study both (1) subjects who have undergone stage I and II palliation and (2)subjects who have undergone stage II palliation only in an attempt to distinguish between sensitization that may occur from allograft exposure during stage I palliation and that which may occur during stage II palliation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Study group I | Study group I will include children who have undergone stage I palliation employing allograft material for left ventricular outflow tract reconstruction at CHOP during infancy (<1 year of age). Stage I palliation is defined as an operation in which augmentation of the native ascending aorta and aortic arch is performed to bypass atresia or critical obstruction of the left heart structures. | |
| Study Group II | Study group II who have undergone stage II palliation in which allograft material is used, but have not undergone antecedent stage I palliation. Stage II palliation is defined as a superior cavopulmonary anastomosis in which the superior vena cava is anastomosed to the ipsilateral pulmonary artery via either the bidirectional Glenn or hemi-Fontan procedures. | |
| Control Group | The control group who have undergone palliative or corrective surgery for congenital heart disease during infancy (<1 year of age) not requiring allograft material. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Primary and Secondary Endpoints
The primary objective is to determine PRA in a cross-sectional analysis of children and adolescents who have undergone stage I palliation for HLHS and related lesions during infancy, and comparing PRA measurements in a similarly aged group of children and adolescents who have undergone congenital heart surgery during infancy without use of allograft.
Measured: 2 years

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 6 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: finished, as of the sponsor's last update on 2 Aug 2017. 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 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?
Primary and Secondary Endpoints (time frame: 2 years). 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 2 Aug 2017.
