Perianal Fistula Due to Crohn's Disease Fistula in Ano | Biological: Human umbilical cord mesenchymal stem cells (UC-MSCs) | Phase 1 |
Design and Investigation:
Dosage and mode of administration
-
First Dosage
- 125 million cells UC-MSCs to be injected
- Procedure: Patients will undergo surgical localization, curettage of the fistulous tract and closure of the internal opening, with intralesional injection of an indicated dose of UC-MSCs
-
Second dosage
- 150 million cells UC-MSCs to be injected
- Procedure: Patients will undergo surgical localization, curettage of the fistulous tract and closure of the internal opening, with intralesional injection of an indicated dose of UC-MSCs
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 7 participants |
Allocation: | N/A |
Intervention Model: | Sequential Assignment |
Intervention Model Description: | First dose is125 million cells and only proceed to second dose of 150 million cells for patients clinically not recovered after 24 weeks from first dose. |
Masking: | None (Open Label) |
Primary Purpose: | Treatment |
Official Title: | A Phase I Study of the Safety of Allogeneic Human Umbilical Cord Mesenchymal Stem Cells (UC-MSCs) for Perianal Fistulas in Patients With Crohn's Disease |
Actual Study Start Date : | March 1, 2022 |
Estimated Primary Completion Date : | December 31, 2024 |
Estimated Study Completion Date : | December 31, 2024 |

Arm | Intervention/treatment |
---|---|
Experimental: Human umbilical cord mesenchymal stem cells (UC-MSCs)
All patients to receive allogeneic UC-MSCs via intralesional injection
|
Biological: Human umbilical cord mesenchymal stem cells (UC-MSCs)
All patients to receive 1st dose of 125 million UC-MSCs and the 2nd dose of 150 million UC-MSCs only if patients have no clinical improvement post 24 weeks after 1st dose |
- Incidence of any treatment-emergent adverse events (TE-AEs) [ Time Frame: 24 weeks ]Any composite of perianal sepsis, persistence of the fistula and allergic reaction.
- Clinical healing [ Time Frame: 24 and/or 48 weeks ]Mainly on re-epithelialization of external opening
