Intervention

Biological:
ASC
Injection of ASC(Autologous Adipose-derived Mesenchymal Stem Cells) to Crohn's Fistula. The ASC injection dose is about 1x10^7 cells of ASC per 1cm^2 of the surface area of the fistula, and the additional injection dose is 1.5 times the initial injection dose. and up to 30% of the ASC injection dose is administered in combination with Fibringlu.
Drug:
Fibringlue
Injection of Fibringlue to Crohn's Fistula. The Fibringlu injection dose is given the size of the fistula that is fill the entire fistula, and the additional injection dose is the same.

Outcome

Type Measure Description Time frame Safety issue
Primary Proportion of subjects who are completely blocked fistula complete blockage In the 8th week after 1st injection
Secondary Proportion of subjects who are completely blocked fistula complete blockage During 12 months after injection
Secondary Proportion of subjects who are more than 50% blocked fistula 50% blockage During 12 months after injection
Secondary Score of evaluation about Investigator satisfaction using questionnaire Score of evaluation about Investigator satisfaction range from 1 to 5. The lower this score, it means that the higher investigator's satisfaction with treatment effect of investigational product. In the 8th week, 6th month and 12th month after final injection
Secondary Proportion of subjects who are confirmed maintenance of fistula blockage by radiology test Radiology test is performed to subjects who are completely blocked fistula. Between 6th month and 12th month after final injection
Secondary Visual improvement effect of perianal fistula wound through photography of it Visual improvement effect of perianal fistula wound is evaluated by photograph of perianal fistula wound before and after the injection(intervention). Immediately before and after the injection(intervention) and during 12 months after injection(intervention)
