Study summary

This is a single site pilot trial to study the feasibility of Fetoscopic Endoluminal Tracheal Occlusion (FETO) therapy in the most severe group of fetuses with congenital diaphragmatic hernia (CDH) at Ann \& Robert H. Lurie Children's Hospital of Chicago (Lurie Children's). This procedure aims to increase fetal lung volume before birth and improve survival after birth. This study will enroll 10 pregnant women who meet study criteria.

Read the detailed description

A Goldballoon Detachable Balloon (GOLDBAL2) will be inserted into the fetal trachea and deployed with the Delivery Microcatheter (BALTACCI-BDPE100) between 27 weeks 0 days and 29 weeks and 6 days of gestation. The fetal tracheal balloon will be removed between 34 weeks 0 days and 34 weeks 6 days of gestation or earlier as indicated.

After balloon insertion, participants will be followed weekly and must reside within 30 minutes of Lurie Children's until balloon removal. Additionally, participants will have restrictions from return to work, exercise, or intercourse. The children's health status will be followed until two years of age.

    • Subject has a support person (e.g., spouse, partner, friend, parent) that is available to stay with her for the duration of the pregnancy near Lurie Children's
    • Willingness to comply with study restrictions on work, exercise, and intercourse
  • Meets psychosocial criteria

Exclusion criteria

Exclusion Criteria:

  • Rubber latex allergy
  • Presence of chromosomal abnormalities or anatomic anomalies that are known to significantly alter survival prognosis (i.e., CDH and congenital heart disease). No cases will be removed post hoc if abnormalities are discovered during post-operative monitoring
  • History of preterm labor, cervix shortened to ≤20 mm at enrollment or at 24 hours prior to FETO balloon insertion procedure) or uterine anomaly strongly predisposing to preterm labor or placenta previa
  • Maternal to fetoscopic surgery or severe maternal medical condition in pregnancy
  • History of incompetent cervix with or without cerclage
  • Placental abnormalities (previa, abruption, accreta, chorioangioma) known at time of enrollment
  • Maternal-fetal Rh isoimmunization, Kell sensitization or neonatal alloimmune thrombocytopenia affecting the current pregnancy
  • Maternal , Hepatitis-B, Hepatitis-C status positive because of the increased risk of transmission to the fetus during maternal-fetal surgery. If the patient's HIV or Hepatitis status is unknown, the patient must be tested and found to have negative results before enrollment
  • Uterine anomaly such as large or multiple fibroids or mullerian duct abnormality
  • There is no safe or technically feasible fetoscopic approach to balloon placement
  • Participation in another intervention study that influences maternal and fetal morbidity and mortality
  • Any other condition which, in the opinion of the investigator, would compromise safety, feasibility or impede compliance
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

What researchers measure

Primary outcomes

  1. Number of successful placements of Goldballoon Detachable Balloon at gestational age 27 weeks 0 days (27w0d) to 29 weeks 6 days (29w6d)

    Successful completion of balloon insertion in fetuses with severe CDH defined as direct visualization of balloon above the carina at the time of FETO procedure.

    Time frame: 27 weeks zero days to 29 weeks 6 days

  2. Number of successful removals of balloon

    Removal of the balloon will ideally be done at 34th week of gestation or prior to delivery.

    Time frame: Removal prior to delivery, ideally at 34 weeks gestation

Secondary outcomes

  1. Change in fetal lung growth

    Prenatal ultrasound will measure the observed-to-expected lung to head ratio (o/e LHR) at weekly visits while the balloon is in place and after balloon removal. Fetal lung growth will be calculated as the difference between the o/e LHR pre-balloon placement and the o/e LHR after balloon removal.

    Time frame: Baseline (before balloon placement) to first ultrasound after balloon removal

  2. Gestational age at delivery

    Gestational age at delivery will be recorded.

    Time frame: At the time of delivery

  3. Infant survival

    Infant survival will be measured from delivery to discharge, at 6, 12, and 24 months of age.

    Time frame: Birth to 24 months

  4. Number of infants requiring extra corporeal membrane oxygenation (ECMO) support

    Use of ECMO will be collected from medical chart review.

    Time frame: Birth to 6 months

  5. Number of infants with sepsis

    Sepsis occurrences will be collected from medical chart review.

    Time frame: Birth to six months

  6. Number of infants with intraventricular hemorrhage (IVH)

    Intraventricular hemorrhage data will be collected from medical chart review.

    Time frame: Birth to six months

  7. Length of hospital stay

    Hospital length of stay will be calculated from medical chart review.

    Time frame: Birth to one year

  8. Number of infants requiring supplemental oxygen

    Supplemental oxygen requirement at time of discharge will be collected from medical chart review.

    Time frame: Birth to 24 months

  9. Number of maternal complications

    Complications during pregnancy, delivery, and first post-partum visit to include: preterm labor, premature rupture of membranes (PROM), preterm premature rupture of membranes (PPROM), oligohydramnios, polyhydramnios, placental abruption, chorioamnionitis, and other infection.

    Time frame: Up to 4-6 weeks post-partum

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Sep 2022 (actual). Primary completion is estimated for Sep 2030, 96 months after the start.

Of 40 interventional studies with no phase under Hernias, Diaphragmatic, Congenital, half reached primary completion within 108 months of starting (the median), counting those still running; a quarter within 33 and three quarters within 133. This study's planned 96 months is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 28, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
