Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Mesenchymal stem cells derived from adipose tissue are pluripotent to differentiate into myocytes, adipocytes or others. They have an immunosuppressive activity. Complex perianal fistula is difficult to cure and easy to relapse. Autologous adipose stem cells have shown efficacy and safety on Crohn's fistula in phase 1 study. Based on these results, the investigators would apply autologous adipose stem cells on complex perianal fistula to evaluate their efficacy and safety.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1

Low dose group

Group Type EXPERIMENTAL

Autologous cultured adipose derived stem cells(low dose group)

Intervention Type BIOLOGICAL

low dose group: 1x10e7 cells/mL At 6 weeks after first stem cell injection, fistula closing was assessed. If it is not completely closed, second injection would be applied in 2 weeks. Additional dosage would be doubled to first dosage.

Group 2

high dose group

Group Type EXPERIMENTAL

Autologous cultured adipose derived stem cells(high dose group)

Intervention Type BIOLOGICAL

high dose group: 2x10e7 cells/mL At 6 weeks after first stem cell injection, fistula closing was assessed. If it is not completely closed, second injection would be applied in 2 weeks. Additional dosage would be doubled to first dosage.
