Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older with perianal fistulas related to Crohn's disease that have not responded to conventional medical therapies.

Probably not a fit

Patients who are pregnant, breastfeeding, or have active infections or certain co-morbidities may not benefit from this study.

What this trial studies

This clinical trial aims to evaluate the safety of allogeneic human umbilical cord mesenchymal stem cells (UC-MSCs) administered via injection for treating complex perianal fistulas in patients suffering from Crohn's disease. The study will involve five participants who will receive a total of 60 million UC-MSCs injected around the fistula tract over five visits, with intervals of 6 to 12 weeks between injections. The primary objective is to demonstrate safety, while secondary objectives include assessing the efficacy of the treatment in improving fistula complications and promoting healing. Regular follow-up examinations will be conducted to monitor patient progress throughout the study.

Why it matters

Potential benefit: If successful, this treatment could provide a novel and effective option for patients with complex perianal fistulas associated with Crohn's disease.

How similar studies have gone: While the use of UC-MSCs in treating perianal fistulas is a relatively novel approach, similar studies involving stem cell therapies have shown promising results in other conditions.
