Safety and Efficacy of MSC-EVs in the Prevention of BPD in Extremely Preterm Infants

Phase I Single Arm, Dose Escalating and Phase II Double Blind, Randomized, Placebo-controlled, Dose Finding Clinical Trial Assessing Safety and Efficacy of Intratracheal Administration of Allogeneic Umbilical Cord Mesenchymal Cells-derived Extracellular Vesicles in Preventing Bronchopulmonary Dysplasia in Extremely Preterm Newborns

Study Type

INTERVENTIONAL

Conditions

Bronchopulmonary Dysplasia

Summary

The phase 1/2 trial aims to evaluate the safety and efficacy of EXOB-001 consisting of extracellular vesicles derived from umbilical cord mesenchymal stromal cells in the prevention of bronchopulmonary dysplasia (BPD) in extremely premature neonates. The study population includes babies born between 23 and 28 (27 + 6 days) weeks of gestational age and body weight between 500g and 1,500 g. Thirty-six subjects will receive one or three administrations of the three doses of EXOB-001 via the endotracheal route in phase 1. In phase 2, two dosages based on the results of phase 1 will be selected and a total of 203 subjects will be randomised to receive either EXOB-001 or placebo (saline solution). Infants will be followed up to 2 years of corrected age (end of study).

Interventions

BIOLOGICALEndotracheopulmonary Instillation, Suspension

The endotracheal administration can be either by endotracheal tube instillation using a 5 French end-hole catheter or by endotracheal tube instillation using the secondary lumen of a dual lumen endotracheal tube. The dose is adjusted to body weight and the endotracheal administration will be performed in an already intubated newborn infant.
