Hidradenitis Suppurativa
Conditions
Brief summary
Multicenter Phase I/II Clinical Trial to Evaluate Safety and Efficiency of Allogenic Adult Mesenchymal Stem Cell from Adipose Tissue in Patients With Hidradenitis Suppurativa
Interventions
Cell therapy treatment will be administered in a single dose at the beginning of the study. The treatment consists of the administration of a single dose of allogeneic adult mesenchymal stem cells from adipose tissue. The dose is 120 million cells (drug volume: 20 ml, concentrated at 6 million cels/ml).
The placebo consists of the administration of the excipient of the suspension without cells. The excipient is a mixture of 50% hyaluronic acid, 49% DMEM without phenol red and 1% L-Alanine-L Glutamine.
