Safety and Efficacy Study of Umbilical Cord-Derived Mesenchymal Stem Cells for Rheumatoid Arthritis

Clinical Trial of Umbilical Cord-Derived Mesenchymal Stem Cells Transplantation for Rheumatoid Arthritis-Phase I/II

Rheumatoid arthritis is a chronic systemic disease, which is characterized by chronic inflammation in the synovial tissue. Rheumatoid arthritis will eventually result in the destruction of cartilage, bone and ligaments and joint deformity. The underlying hypothesis is that umbilical cord-derived mesenchymal stem cell (UC-MSCs) has anti-inflammatory effects and thus potentially alleviates the progression of rheumatoid arthritis. The study is to explore the safety and efficacy of UC-MSCs transplantation in treatment of rheumatoid arthritis.

This study was supported by the National Natural Science Foundation of China (30872618)，The Shanxi Province Social Development Public Relations Project (2012K13-02-35), and The Military Medicine and Public Health Plan (CLZ120GA23)

• Women of reproductive potential may not participate unless they have agreed to use an effective contraceptive method while on this trial. Women of child-bearing potential must have a pregnancy test performed within 72 hours prior to initiation of treatment.

Exclusion Criteria:

• Any history of ongoing, significant or recurring infections.
• Any active inflammatory diseases other than RA.
