Clinical Trial Summary

The purpose of this study is to test the safety and efficacy of Umbilical Cord-derived Mesenchymal Stromal Cells (UCMSC) for the treatment of Systemic Sclerosis (SSc).


Clinical Trial Description

A single-center, three-arm, randomized, double-blind, placebo-controlled trial is proposed. A total of 18 SSc patients will be enrolled in 3 successive blocks of 6 patients each. After being informed about the study and potential risks, all patients giving written informed consent will be randomized to one of two treatment arms or a placebo arm (total of 6 patients per arm). Within each block, the 6 patients will be randomized in a 2:2:2 ratio in one of the following arms: placebo, 1 infusion of UCMSC (M0), or 2 infusions of UCMSC (M0, M3). Second infusions of UCMSC will be performed only in the absence of Treatment Related Severe Adverse Events (TRSAE). Randomization into blocks 2 and 3 will be staggered, to allow the detection of TRSAE prior to inclusion of patients in a subsequent block, i.e. the second block will be randomized only in the absence of TRSAE one month after the first infusion of all 6 patients in block one, and similarly for the third block. ;
