About this study

Official title: Randomized Trial of Fetoscopic Endoluminal Tracheal Occlusion (FETO) Versus Expectant Management During Pregnancy in Fetuses With Left Sided and Isolated Congenital Diaphragmatic Hernia and Moderate Pulmonary Hypoplasia.

Isolated Congenital Diaphragmatic Hernia (CDH) can be diagnosed in the prenatal period, and remains associated with a 30 % chance of perinatal death and morbidity mainly because of pulmonary hypoplasia and pulmonary hypertension. In addition, in the survivors there is a high rate of morbidity with evidence of bronchopulmonary dysplasia in more than 70% of cases. The risk for these can be predicted prenatally by the ultrasonographic measurement of the observed/expected lung area to head circumference ratio (O/E LHR) which is a measure of pulmonary hypoplasia. Also position of the liver is predictive of outcome.

The proposing consortium has developed a prenatal therapeutic approach, which consists of percutaneous fetoscopic endoluminal tracheal occlusion (FETO) with subsequent removal of the balloon. Both procedures are performed percutaneously, there is now experience with more than 150 cases and it has been shown to be safe for the mother. We have witnessed an improvement of survival in fetuses with a predicted chance of survival of less than 30% (referred to as fetuses with severe pulmonary hypoplasia; O/E LHR <25% and liver herniation) to 55% on average. Also there is an apparent reduction in morbidity with the rate of bronchopulmonary dysplasia decreasing from the estimated rate of more than 70% to less than 40% in the same severity group.

Further we have shown that results of FETO are predicted by LHR measurement prior to the procedure, so that better results can be expected in fetuses with larger lung size. Therefore we now aim to offer FETO to fetuses with moderate CDH (=O/E LHR 25-34.9%, irrespective of the liver position as well as O/E LHR 35-44.9% with intrathoracic herniation of the liver). When managed expectantly the estimated rate of postnatal survival is 55%.

This trial will test whether temporary fetoscopic tracheal occlusion rather than expectant management during pregnancy, both followed by standardized postnatal management increases survival or decrease oxygen dependency at 6 months of age. The balloon will be placed between 30 and 31+6 weeks, and will be removed between 34 and 34+6 weeks.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 7 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 3 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States, France, Italy, Australia, Belgium and 5 more countries. 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?

Survival at discharge (time frame: at the time of discharge from NICU, approximately 2 months). The study lists 2 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 NCT00763737, which also lists 19 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 3 Dec 2020.
