简要总结

Orofacial manifestations and microstomia are a frequent complication in systemic sclerosis (SSc) with a major impact on oral hygiene, dental care and quality of life. Peri-oral injection of allogeneic cultured adipose-derived stromal cells constitutes a promising approach to treat scleroderma-induced mouth fibrosis where no alternative therapy is validated. The aim of this phase 2 study is to compare efficacy and safety of perioral injection of allogeneic cultured adipose-derived stromal cells (AdMSC) versus placebo to improve oro-facial fibrosis in patients with systemic sclerosis.
