Clinical Trial Summary

Bronchopulmonary dysplasia (BPD) is a disease that affects preterm newborn patients, preventing their lungs from developing properly. Allogeneic fetal stem mesenchymal cells from umbilical cord could reduce the prevalence of BPD in this patients.

Description:

Bronchopulmonary dysplasia (BPD) is a disease that affects preterm newborn patients, preventing their lungs from developing properly, and it is a disease that is nowadays increasing due to the improvement in the survival of this patients (affecting 15-50% of them).

In the Fase I Clinical Trial, the use of allogeneic fetal stem mesenchymal cells from umbilical cord proved to be safe, with no mortality or Adverse Events reported. The Fase II Clinical Trial is based in the hypothesis that the administation of mesenchymal stem cells is not only safe but feasible and can help reducing the chance of a preterm newborn patient developing BPD.
