6Adipose-derived stem cells have properties of differentiation to various types of cells, immunomodulatory effects. adipose-derived stem cells (ASCs) show also low immunogenicity.
Anterogen has developed ANTG-ASC(Autologous ASC) which has shown good efficacy and safety in Phase I and II study on the patients with Crohn's fistula.
However, Crohn's patients are sometimes not fat enough to extract fat tissue for culturing ASCs. Therefore the investigators have planned to study allogenic ASCs for safety and efficacy in patients with Crohn's fistula.
ALLO-ASC 1xE7 cells/mL is injected once along the fistula. If there is no safety issue for 4 weeks, 3 more people could be enrolled who are subject to ALLO-ASC 3xE7 cells/mL.
For ALLO-ASC 1xE7 cells/ml,3 patients are to be enrolled. If there is no safety issue, 3 more patients will be enrolled to be treated with ALLO-ASC 3xE7 cells/ml.
Inclusion Criteria: Diagnosed with Crohn's disease Crohn's fistula which has been lasted at least for 3 months Negative for beta-HCG pregnancy test Exclusion Criteria: Medical history with Variant Creutzfeldt Jacobs Disease Allergic to anesthetics or bovine protein or fibrin glue autoimmune disease other than Crohn's disease Infectious disease Sepsis or active tuberculosis pregnant or breast feeding woman Inflammatory Bowel disease other than Crohn's disease active crohn's disease with CDAI score > 200 malignant tumor fistula's diameter > 2 cm
