Darvadstrocel for Crohn's Fistula in the Realworld

Background Perianal fistula may affect 15-50% of patients with Crohn's disease (CD). Treatment is complex, requiring a multidisciplinary approach. Darvadstrocel (allogeneic mesenchymal cells obtained from lipoaspirates) was approved in 2018 by the European Medicines Agency and Spanish Agency of Medicines and Medical Products as a treatment for fistulas in CD. Recent European Crohn's and Colitis Organisation (ECCO) andSpanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) guidelines state that darvadstrocel is effective with a favourable safety profile,with a strong level of evidence (level 2).With this study we want to see the real efficacy of darvadstrocel in a Spanish population after 6 months of follow-up.
