About this study
To evaluate the effects (up to one year of age) of indomethacin on the clinical course of patent ductus arteriosus (PDA) in premature infants (24 hours old or less) and to assess the relative merits of indomethacin and surgery in infants with persistent respiratory distress who were not treated early with indomethacin. Two concurrent trials were performed.
Read the detailed description
BACKGROUND:
The incidence of patent ductus arteriosus is higher in premature infants than in full-term infants and is highest in premature infants who have respiratory distress syndrome. It is generally agreed that intervention in an asymptomatic infant with a small left-to-right shunt is unnecessary, since the patent ductus almost invariably closes spontaneously and thus does not require surgery. A few infants will demonstrate signs of a large shunt during the course of respiratory distress syndrome. Many of these infants will improve with medical management of congestive heart failure, but others require surgical closure. A third group of babies with respiratory distress have severe progressive pulmonary disease requiring ventilatory support. There was disagreement as to whether elimination of the patent ductus in these infants resulted in decreased mortality. A variety of therapeutic approaches was being used, and there was no convincing evidence of the superiority of one treatment over another.
DESIGN NARRATIVE:
Trial A was a randomized, double-blind trial in which indomethacin plus usual medical therapy was compared with a placebo plus medical therapy. Where this regimen was unsuccessful, the code was broken, and infants who received indomethacin were treated surgically. Infants who had received placebo in Trial A were entered, if there were no contraindications to indomethacin, into Trial B. In Trial B, infants were randomized to surgery or indomethacin therapy. Those in whom indomethacin treatment was unsuccessful were treated surgically. The Recruitment and Intervention Phase began in April 1979. All patients were enrolled by March 31, 1981, and followed for one year after enrollment.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
To evaluate the effects (up to one year of age) of indomethacin on the clinical course of patent ductus arteriosus (PDA) in premature infants (24 hours old or less) and to assess the relative merits of indomethacin and surgery in infants with persistent respiratory distress who were not treated early with indomethacin. Two concurrent trials were performed.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing indomethacin and surgery, cardiovascular in people with Cardiovascular Diseases and Defect, Congenital Heart, run by National Heart, Lung, and Blood Institute (NHLBI).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 13 Dec 2013. Status can change between updates, so confirm with the study contact before making plans.
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 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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00000494, which also lists 3 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 13 Dec 2013.
