Study Design

Observational model case-only
Time perspective prospective
Low Dose Group (3 subjects): 1.0 x 10^7 cells/kg, High Dose Group (6 subjects): 2.0 x 10^7 cells/kg
pneumostem® Human umbilical cord blood-derived mesenchymal stem cells
A single intratracheal administration Low Dose Group (3 patients): 1.0 x 10^7 cells/kg, High Dose Group (6 patients): 2 x 10^7 cells/kg * The subjects were administered with Pneumostem® in the earlier part of the phase I study. No drugs/biologics are administered during this part of the study.

time frame: at corrected age of 10 months (±2 months) and 21 months (±3 months)
time frame: Corrected gestational age of 4-6months, 8-12months, 18-24months

Eligibility Criteria

Male or female participants from 4 months up to 2 years old.

Additional Information

Official title Long Term Follow-Up Study of the Safety and Exploratory Efficacy of Pneumostem® in Premature Infants With Bronchopulmonary Dysplasia
Principal investigator Won-Soon Park, MD, PhD
Description Bronchopulmonary dysplasia (BPD) is the most common cause of death for premature newborns with low birth weights. In addition, many children who recover from the disease suffer from various complications such as prolonged hospitalization, pulmonary hypertension, and failure to thrive. It has been reported that bone marrow-derived mesenchymal stem cells (BM-MSC) can differentiate into pulmonary epithelial and pulmonary endothelial cells. Some animal studies showed that BM-MSCs differentiate into bronchial cells and type 2 pneumocytes in rats with pneumonia and improve the fibrosis that occur after administration of bleomycin. Based on the findings, it is considered that mesenchymal stem cell therapy can help regenerate the damaged lung as well as BPD that cause lung inflammation, fibrosis, deficiency of type 2 pneumocytes, and so on. PNEUMOSTEM® consists of human umbilical cord blood-derived mesenchymal stem cells and is intended to treat BPD in premature infants. This is a long term follow-up study of the earlier part of the phase I clinical trial.
