Clinical Trial to Evaluate Safety and Efficiency of Mesenchymal Stem Cell in Patients With Hidradenitis Suppurativa

A Multicenter Phase I/II Clinical Trial, Randomized, Double Blind, Controlled With Placebo to Evaluate Safety and Efficiency of Allogenic Adult Mesenchymal Stem Cells From Adipose Tissue in the Treatment of Draining Fistulas in Patients With Hidradenitis Suppurativa
