Is this trial a fit for you?

Likely a good fit

Ideal candidates are extremely preterm infants aged 0 to 10 days, born between 23 and 28 weeks of gestation, and requiring mechanical ventilation.

Probably not a fit

Patients with congenital heart defects or serious lung malformations may not benefit from this treatment.

What this trial studies

This phase 1/2 trial evaluates the safety and efficacy of EXOB-001, which consists of extracellular vesicles derived from umbilical cord mesenchymal stromal cells, in preventing bronchopulmonary dysplasia (BPD) in extremely premature infants. The study will involve infants born between 23 and 28 weeks of gestational age and weighing between 500g and 1,500g. Participants will receive one to three doses of EXOB-001 via endotracheal administration, with follow-up extending to two years of corrected age. The trial aims to determine the optimal dosage based on initial safety and efficacy results.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the incidence of bronchopulmonary dysplasia in extremely preterm infants, improving their long-term respiratory health.

How similar studies have gone: While the use of extracellular vesicles in this context is relatively novel, preliminary evidence suggests potential efficacy in similar approaches.

Exclusion Criteria:

* Surfactant administration less than 24 hours prior to (first) IMP administration.
* Has a congenital heart defect, except for patent ductus arteriosus (PDA), atrial septal defect or a small/moderate, restrictive ventricular septal defect.
* Has a serious malformation of the lung, such as pulmonary hypoplasia/aplasia, congenital diaphragmatic hernia, or any other congenital lung anomaly.
* Being treated with inhaled nitric oxide.
* Has a known chromosomal abnormality (e.g., Trisomy 18, Trisomy 13, or Trisomy 21) or a severe congenital malformation (e.g., hydrocephalus and encephalocele, trachea-oesophageal fistula, abdominal wall defects, and major renal anomalies).
* Has had a known severe congenital infectious disease (i.e., herpes, toxoplasmosis rubella, syphilis, human immunodeficiency virus, cytomegalovirus, etc.).
* Active systemic infection, severe sepsis, or septic shock at Screening up to baseline (phase I) or randomization (phase II).
* Underwent a surgical procedure (requiring admission to an operating room) within 72 hours before baseline (phase I)/randomization (phase II) or who is anticipated to have a surgical procedure (requiring admission to an operating room) within 72 hours before or following baseline (phase I)/randomization (phase II).
* Has had a Grade 3 or 4 intraventricular haemorrhage (IVH).
* Has active pulmonary haemorrhage.
* Has periventricular leukomalacia (PVL).
* The subject is currently participating in any other interventional clinical study.
* The subject is, in the opinion of the Investigator, so ill that death is inevitable, or is considered inappropriate for the study such as an infant that received thoracic compressions and/or adrenaline administration during stabilization in the delivery room and for any reason(s) other than those listed above.
