Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with urge fecal incontinence due to external anal sphincter dysfunction who have not responded adequately to conservative treatments.

Probably not a fit

Patients whose fecal incontinence is caused by factors other than external anal sphincter dysfunction may not benefit from this treatment.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the safety and effectiveness of autologous skeletal muscle-derived cells for patients suffering from urge fecal incontinence due to dysfunction of the external anal sphincter. Participants will receive either the muscle cell treatment or a placebo, and their outcomes will be assessed over time. The study focuses on individuals who have not found relief from conservative treatments and have specific measurable impairments in anal sphincter function. The goal is to determine if this innovative approach can significantly improve symptoms and quality of life for affected patients.

Why it matters

Potential benefit: If successful, this treatment could provide a new, effective option for patients suffering from fecal incontinence, improving their daily functioning and quality of life.

How similar studies have gone: While this approach is innovative, similar studies using muscle-derived cells for other conditions have shown promise, indicating potential for success in this area.
