Study summary

The purpose of this pilot study is to evaluate the feasibility of using Fetoscopic Endoluminal Tracheal Occlusion (FETO) in 10 pregnant individuals carrying fetuses with severe congenital diaphragmatic hernia (CDH). FETO surgery will be performed at 27 weeks - 29 weeks and 6 days of gestation, and the fetoscopic removal of the balloon will be performed at 34 weeks - 34 weeks and 6 days of gestation. The primary endpoint is successful placement and removal of the balloon.

Inclusion criteria

  1. Provision of a signed and dated form
  2. Pregnant individuals age 18 years and older
  3. Singleton pregnancy
  4. A normal karyotype with confirmation by culture results, CMA with non-pathologic variants, whole exome or genome sequencing (WES or WGS).
  5. Isolated left CDH with severe pulmonary hypoplasia with o/e LHR less than 25% with liver up (measured at 18 weeks 0 days to 29 weeks 5 days of gestation)
  6. Isolated right CDH with severe pulmonary hypoplasia with o/e LHR equal or less than 30% with liver up (measured at 18 weeks 0 days to 29 weeks 5 days of gestation)
  7. Gestational age at FETO procedure 27 weeks 0 days to 29 weeks 6 days as determined by clinical information (LMP) and evaluation of first ultrasound
  8. Stated willingness to comply with all study procedures and lifestyle considerations and availability for the duration of the study
  9. Willing to reside within a 30-minute distance of the NYULH in the time period between the FETO placement procedure and the balloon retrieval procedure, and ability to maintain follow-up appointments
  10. The subject has a support person (e.g., spouse, partner, friend, parent) who is available to stay with her for the duration of the pregnancy near NYULH.
  11. Willing to comply with restrictions of daily living, including inability to exercise, have intercourse, or return to work
  12. Meets psychosocial criteria

Exclusion criteria

Exclusion Criteria:

  1. Natural rubber latex allergy
  2. Additional fetal anomaly and chromosomal abnormalities, associated anomalies recognized to alter survival prognosis (i.e., congenital heart disease) or presence of an underlying genetic syndrome (i.e., Fryns) by ultrasound, MRI or echocardiogram at the fetal treatment center.
  3. Signs of preterm labor, cervix shortened to ≤20 mm at enrollment or at 24 hours prior to FETO balloon insertion procedure) or a uterine anomaly strongly predisposing to preterm labor.
  4. Maternal to fetoscopic surgery or severe maternal medical condition in pregnancy
  5. History of incompetent cervix with or without cerclage
  6. Placental abnormalities (previa, abruption, accreta, chorioangioma) known at time of enrollment
  7. Maternal-fetal Rh isoimmunization, Kell sensitization or neonatal alloimmune thrombocytopenia affecting the current pregnancy
  8. 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
  9. Uterine anomaly such as large or multiple fibroids or mullerian duct abnormality
  10. There is no safe or technically feasible fetoscopic approach to balloon placement
  11. Participation in another intervention study that influences maternal and fetal morbidity and mortality
  12. Any other condition which, in the opinion of the investigator, would compromise safety, feasibility or impede compliance.
  13. Bilateral CDH, isolated left sided CDH with o/e LHR >/= 25% and isolated right sided CDH >30%
  14. No intrathoracic liver herniation
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.

    Congenital diaphragmatic hernia (CDH)

    FETO surgery will be performed at 27 weeks - 29 weeks and 6 days of gestation, and the fetoscopic removal of the balloon will be performed at 34 weeks - 34weeks and 6 days of gestation.

    Device: Goldballoon Detachable Balloon (GOLDBAL2)

What researchers measure

Primary outcomes

  1. Number of successful balloon placements at age 27w0d - 29w6d and removal at 34 weeks of gestation

    Time frame: Up to 35 weeks

Secondary outcomes

  1. Difference between the relative lung volume (o/e LHR and o/e TLV)

    Fetal lung growth will be calculated by the difference between the relative lung volume (observed-to-expected (o/e) lung-to-head ratio (LHR) and o/e total lung volume (TLV)) measured before and after FETO

    Time frame: Baseline, removal of balloon (up to 35 weeks)

Individual participant data

Plan to share: Yes — The de-identified participant data from the final research dataset will be shared upon reasonable request beginning 9 to 36 months after publication or as required by a condition of awards or supporting agreements, provided the requesting investigator executes a data use agreement with NYU Langone Health. This instance of data sharing will also require separate IRB review as well as review from NYU Langone's Data Sharing Strategy Board (DSSB). Requests should be directed to: jose.peiro@nyulangone.org. Besides the study publications, by FDA regulation, the data will be shared with the NAFTNet FETO registry, which will involve all of the individual participant data collected during the trial, after deidentification. The protocol and statistical analysis plan will be posted on Clinicaltrials.gov only as required by federal regulation or supporting awards and agreements.

Supporting information: Study protocol, Statistical analysis plan

Time frame: Beginning 9 months and ending 36 months following article publication or as required by a condition of awards and agreements supporting the research.

Access criteria: The investigator who proposed to use the data will be granted access upon reasonable request. Requests should be directed to jose.peiro@nyulangone.org. To gain access, data requestors will need to sign a data access agreement. This instance of data sharing will also require separate IRB review as well as review from NYU Langone's DSSB.

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

Start is estimated for Sep 2026; primary completion for Sep 2029, 36 months later.

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 36 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 Aug 17, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
