Clinical Trial Summary

This is a phase I study to evaluate the safety of ALLO-ASC-CD for the treatment of crohn' disease. ALLO-ASC-CD is intravenous infusion containing allogenic adipose-derived mesenchymal stem cells.

Description:

Adipose-derived stem cells are directed to injured tissue, and reduce inflammation. Furthermore, their immunomodulatory effects are significant for treating immune-related diseases, such as crohn's disease. Finally, ALLO-ASC-CD may provide a new option in treating a crohn's disease.
