A Follow-up Study to Evaluate the Safety of ALLO-ASC-CD in ALLO-ASC-CD-101 Clinical Trial

ALLO-ASC-CD is intravenous infusion containing allogenic adipose-derived mesenchymal stem cells. Adipose-derived stem cells are directed to injured tissue, and reduce inflammation. Furthermore their immunomodulatory effects are significant for treating immune-related disease. Finally, ALLO-ASC-CD may provide a new option in treating a crohn's disease. This study is a follow-up study without intervention.
