Allogeneic Adipose Tissue-derived Mesenchymal Stem Cells for the Induction of Remission in Ulcerative Colitis

• Status: Unknown status
• Trial end date: 2013-12-01
• Target enrollment: 0
• Participant gender: All

Summary

The aims of our study are to evaluate the feasibility and safety of endoscopic injection of adipose tissue-derived mesenchymal stem cells in human subjects with moderate active ulcerative colitis, assessing the absence of adverse events associated to the investigational drug, and to evaluate the efficacy of the treatment to induce remission of moderate active ulcerative colitis, by improvements in disease activity index, quality of life index, and endoscopic index.
