Safety and Efficacy of FETO in CDH: A Phase III Trial
United States80 participantsStarted 2025-04-07
Plain-language summary
Congenital diaphragmatic hernia (CDH) is a birth defect characterized by the development of a hole in the diaphragm, the breathing muscle that separates the chest from the abdomen. As a result, organs in the abdomen can move into the chest and press on the developing lungs. This prevents the lungs from growing and developing normally.
In severe cases, CDH can lead to serious disease and death at birth. For these babies, treatment before birth may allow the lungs to grow enough before birth so these children are capable of surviving and thriving.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Pregnant women age 18 years and older
. Singleton pregnancy
. Normal fetal karyotype with confirmation by culture results, whole exome sequencing (WES), whole genome sequencing (WGS), or chromosomal microarray with non-pathologic variants. Results by fluorescence in situ hybridization (FISH) will be acceptable if the patient is greater than 26 weeks.
. Gestational age at enrollment is prior to 29 weeks 6 days
. Liver is intrathoracic
. Isolated left congenital diaphragmatic hernia (CDH) with observed/expected lung to head ratio (O/E LHR) of less than 30% at enrollment (18\^0 to 29\^5 weeks), or:
. Isolated right CDH with O/E LHR equal to or less than 45% at enrollment (18\^0 to 29\^5 weeks).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Successful placement and removal of the FETO Device
Timeframe: 24 months
2
Comparison of neonatal survival rates of LCDH cases between intervention and control groups
Timeframe: 24 months
3
Comparison of neonatal survival rates of RCDH cases between intervention and control groups
Timeframe: 24 months
4
Assessment of complications associated with the FETO intervention
. Cervical length by transvaginal ultrasound equal to or greater than 20 mm within 24 hours of fetoscopic endoluminal tracheal occlusion (FETO) procedure
Exclusion criteria
. Patient is less than 18 years of age
. Multi-fetal pregnancy
. History of natural rubber latex allergy
. Preterm labor, cervix shortened (less than 20 mm at enrollment or within 24 hours of FETO balloon insertion procedure) or uterine anomaly strongly predisposing to preterm labor, placenta previa
. Psychosocial ineligibility, precluding consent:
. Bilateral CDH, isolated left sided CDH with O/E LHR greater than or equal to 30% (measured at 18\^0 to 29\^5 weeks), isolated right sided CDH with O/E LHR greater than 45% (measured at 180 to 295 weeks), as determined by ultrasound
. No Liver herniation into thoracic cavity.
. Additional fetal anomaly by ultrasound, magnetic resonance imaging (MRI), or echocardiogram at the fetal treatment center. Exclude chromosomal abnormalities, associated anomalies recognized to alter survival prognosis (ie. CDH and congenital heart disease) or presence of an underlying genetic syndrome (ie. Fryns).
