Clinical Trial Summary

This study is to evaluate the efficacy and safety of PNEUMOSTEM® for the Prevention and Treatment of Severe Bronchopulmonary Dysplasia (Severe BPD) in Premature Infants. Half of subjects will receive PNEUMOSTEM, while the other half will receive a placebo.

Description:

Bronchopulmonary dysplasia (BPD) is a chronic lung disease in which premature infants and it results in significant morbidity and mortality. PNEUMOSTEM is intended to prevent and treat BPD by modulating inflammation and repairing damaged lung tissue in premature infants through paracrine effects.
