- Conditions
- Faecal Incontinence
- Interventions
- Drug: Infusion of mesenchymal stem cells from adipose tissueOther: Infusion of placebo
- Registration Number
- NCT02292628
- Lead Sponsor
- Andalusian Initiative for Advanced Therapies - Fundación Pública Andaluza Progreso y Salud
- Brief Summary
This is a clinical trial phase I/II, double blind, randomized to compare in two groups of patients to evaluate the safety and efficacy of the autologous mesenchymal stem cells from the adipose tissue (CMMAd) in the treatment of the faecal incontinence.
- Detailed Description
In the phase of recruitment, of 20 months of duration, there will be included 16 participants who will be randomized to one of the groups of intervention (8 patients group CMMAd / 8 patients group placebo). The phase of follow-up of every patient will be 12 months, though, provided that these patients are seen regularly in the study sites of the study, once concluded his follow-up will be continued to be able to obtain safety information and efficacy to 24 months.
