About this study

Official title: Triostat in Children During CardioPulmonary Bypass (CPB)

This is a study to determine the safety and efficacy of liothyronine sodium/triiodothyronine (Triostat), a synthetic thyroid hormone, when given to infants with congenital heart disease during cardiopulmonary bypass surgery.

Read the detailed description

Patients will be randomized to receive study drug or placebo and randomization will occur stratified to each diagnostic category. All patients undergo preoperative echocardiograms to provide preoperative cardiac function data. The study drug or placebo will be provided in the operating room as an iv bolus just prior to cardiopulmonary bypass and as a bolus delivered on release of the aortic cross-clamp. This will be followed by iv for 12 hours. Operative data will be collected including CPB time, aortic cross-clamp time, length and degree of hypothermia. These data will be extracted from the anesthesia record.

Being tested

Study groupRoleWhat they receive
Liothyronine Sodium/TriiodothyronineActive comparatorbolus administration of Liothyronine Sodium/Triiodothyronine (Triostat) immediately prior to CPB institution and after removal of aortic cross clamp, followed by repeated boluses, will be safe and will result in significant improvements in postoperative and clinical outcome parameters and cardiac contractile function.

What is being measured

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

  1. duration of mechanical ventilation after cardiopulmonary bypass.

    Reducing the length of ventilatory support minimizes other postoperative complications, which can contribute to morbidity.

    Measured: 0 to 72 hours

Secondary outcomes (1)
  1. Assess other parameters

    • Need for mechanic circulatory support, fluid balance (intake and output); urine output
    • Echocardiographic measures to include end-systolic wall stress/fractional shortening ratio
    • Myocardial performance index (Doppler derived), cardiac index (Doppler derived)
    • Heart rate, blood pressure and central venous pressure
    • Free and total T3 levels
    • Others: All medications including inotropic agents will be recorded with respect to time initiated, terminated, and dosage will be recorded for exploratory analyses.

    Measured: 0 to 72 hrs

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Liothyronine sodium/triiodothyronine and Cardiopulmonary bypass and cardiac surgery in people with Heart Defects, Congenital, run by Michael Portman 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 8 inclusion and 1 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 5 Aug 2013. 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. Some participants in this study may receive a placebo. 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?

duration of mechanical ventilation after cardiopulmonary bypass. (time frame: 0 to 72 hours). 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 NCT00027417, which also lists 1 linked publication.

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 Aug 2013.
