What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Non-invasive NAVAProcedure or surgery
Initiate respiratory assist with NIV-NAVA within 48 hours. The setting of respiratory support will be adjusted based on clinical conditions of each subject. NIV-NAVA could be switched to nasal continuous airway pressure or high flow nasal cannula, and it also could be stopped after initial stabilization.
In cases of respiratory distress syndrome, lung surfactant will be administered via the less invasive surfactant administration (LISA) method and avoid endotracheal intubation whenever possible. For who intubated in the delivery room, extubation with NIV-NAVA should be considered as soon as possible. Endotracheal intubation with invasive ventilation could be applied when clinical deteriorations happens.
| Study group | Role | What they receive |
|---|---|---|
| NIV-NAVA application | Preterm infants born between 27 weeks 0 days to 31 weeks 6 days of gestation requiring respiratory support within 48 hours after birth Receives: Procedure: Non-invasive NAVA |

Questions about this trial
What is this clinical trial studying?
An observational study of Preterm Infant, run by Korea University Anam Hospital at 2 sites in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 5 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in South Korea. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Juyoung Lee, Professor (+82-2-920-5647, juyounglee@korea.ac.kr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Rate of Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) failure (time frame: through the study completion, during the hospital stay in neonatal intensive care unit up to 3 months). 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 NCT06786039, which also lists 1 linked publication.
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 5 Aug 2026.
