Study Description

Brief Summary:

The clinical study with UMC119-01 is designed to investigate the safety in patients with bronchopulmonary dysplasia ("BPD"). This will be a dose escalation, open-label, single-center study in infants at high risk for BPD.

Criteria

Inclusion Criteria:

Neonatal infants who fulfil all of the following criteria will be enrolled:

1. Subjects of postnatal age between 3 to 30 days.
2. Are male and female infants born at GA between 23 weeks to 29 weeks. The postmenstrual age of subject received UMC119-01 should be no more than PMA36 weeks.
3. Subjects with birth weight between 501g to 1249 g.
4. Have endotracheal tube in place as part of SoC for preterm infants with BPD at screening and on treatment visit (Day 0), and that they will have not been intubated for the purposes of this study.
5. A subject who is intubated and receiving mechanical ventilation with a fraction of inspired oxygen (FiO2) of 0.25 or greater at Screening.
6. A subject who has had either a deterioration or no change in the setting of mechanical ventilation within the 24 hours before trial enrollment.
7. Written informed consent has been provided by the subject's parents, legal guardians, or a legal representative, who agree to comply with all of the study procedures, including those in the long-term safety surveillance period.

Exclusion Criteria:

Neonatal infants who meet any of the following criteria will be excluded:
